All directors attended the meeting of the Board of Directors for deliberation of this annual report. During the reporting period, there was no significant change in the risks faced by the Company. The Company has been trying to identify all kinds of risks and actively take countermeasures to avoid and reduce the risks. (1) COVID-19 risk: As COVID-19 continues to spread, the global market is facing uncertainties. The Company will pay close attention to pandemic, making responses through various online and offline channels to advertise products and provide services and try its best to reduce the impact of the pandemic. (2) Risk of technology upgrading: the video surveillance industry is a typical technology-intensive industry, which is changing extremely fast. If the Company is unable to keep up with development trends in the industry's technology, to pay full attention to customers' diversified individual needs, and to be followed by sufficient R&D investments, it will still face the risk of losing market competitiveness due to discontinuous innovation. By increasing R & D investment, the Company continues to strengthen research on core technologies in AI, video cloud, machine vision and other fields, and reserves product, technology, management and talent resources for a broader market in the future, so as to 2 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. achieve sustainable and steady development of business. (3) Risk of business model change: with the development of network communications, cloud computing, and big data, AI and other technologies, as well as the upgrades of apps in smartphones, the business model in the IoT era may have an impact on the traditional industry development. If an enterprise cannot grasp opportunities brought about by the business model transformation in a timely manner, it may face the risk that the original market structure becomes broken. The Company continues to focus on and study the major changes in global economy, industry and technology, analyze the industry development logic, and predict the evolution of global video surveillance industry and IoT industry, the continuous integration of video, information communication and digital technologies, diversification and uncertainty of customer demands. While consolidating the advantageous market, The Company actively explores and pilots new businesses and new commercial mode, and carry out business and technical layout. (4) Risk of product safety: the Company attaches great importance to and continuously strengthens resource investment to ensure safe and reliable operations of the security system so as to respond to the product security risks on the Internet. However, hackers attacks, computer viruses, physical security vulnerabilities, natural disasters, accidents, power interruptions, telecommunications failures, terrorism, and warfare events may still occur from time to time, resulting in security vulnerabilities, system failures, or service interruptions. The Company has founded a cyber security committee, and set up a professional security team to develop company-level product safety plan, ensuring product safety in whole process from requirements to design, coding, and testing process. At the same time, the Company actively carry out technical exchanges and cooperation with mainstream safety enterprises, safety evaluation agencies and corresponding industry associations to provide customers with safe products and solutions. (5) Intellectual property risk: the promotion of the company's globalizatio n and self-owned brand strategy will likely bring about intellectual property risks and patent infringement, which may cause fluctuation in business relations and public opinions, increasing lawsuits and rising costs. The Company attaches great importance to technological innovation and has established protection and management mechanism for 3 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. intangible assets such as innovation achievements, self-owned brands, trade secrets, and constantly gathers advantageous IP assets; With IP compliance risk control system, the Company continues to strengthen its ability to understand and grasp the IP laws and regulations, administrative and judicial environment of the region where the company's business is located in. (6) Exchange rate risk: The Company's export transactions are mostly settled in United States Dollars ("USD"), while overseas sales have increased continuously. Therefore, fluctuations in the foreign exchange rate have the potential to affect the profits of the Company. As US dollar is the settlement currency, the Company hedges and avoids the risk of exchange rates by centralized management of exchange capitals, purchase and payment hedging and other methods. (7) Risk of declined local fiscal capacity: At present, local fiscal debt is relatively high. If the local fiscal paying capacity is reduced, it may lead to the slowdown in the growth of industry demands, extensions of project time, longer periods for companies to withdraw capital, and customers' payment delay. The Company continues to improve our internal control system and optimize the project review methods, select local projects carefully and assess project risks systematically, prudently assess the market logic and cash flow balance logic, control the risks reasonably, make plans to deal with cash flow shortage, project delay and other risks, and reduce the risk of delayed payment. (8) Risk of international operations: The Company's products and solutions are available in more than 100 foreign countries and regions. International business may be exposed to the risks of trade protection and political turmoil (such as local wars) in the countries and regions where it is located. The Company actively guards against and responds to the risk of international operation by establishing an overseas compliance risk control system. It continuously strengthens the understanding and adaptability of the laws and regulations as well as the political and economic environment of the regions where its business is involved, and formulates differentiated business strategies based on "one country, one policy" in accordance with the changes in politics and economy of different regions to reduce operational risks. (9) Risk of the supply chain: As the prices of global commodities continue to rise and 4 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. the prices of raw materials fluctuate, through special operations, the Company has identified various potential supply risks. By making backup plans and increasing supply channels, the Company has diversified its supply sources to strengthen the continuous and secure supply of key materials and ensure the security of the supply chain.

During the reporting period, the Company won the first place in 13 competitions and evaluations related to AI, and applied for more than 600 patents related to AI. The number of AI smart devices shipments (sets) has a year-on-year growth of more than 80%. Fully Build Scenario-based AI Business Capability 2021 marks a year of acceleration of global digital transformation. The Company has been continuously building the AI scenario-based capabilities in more than 20 industries such as urban management, transportation, construction, electricity, finance, manufacturing, petroleum and chemistry, and logistics, and has added more than 10 scenarios such as steel, health, coal and emergency rescue. The Company has good understanding of clients' production management processes, and provides abundant scenario-based AI application schemes through innovating technologies and upgrading systems, so as to improve the production quality and efficiency for clients and achieve win-win results. (1) Efficiently meet the demand of scenario-based intelligent solutions of each industry and accelerate the realization of intelligent business through the business architecture featuring "dot+line+network" Dot: More than 1,000 industry-leading algorithms have been released to quickly meet various needs. Line: To meet the needs of various business scenarios, a large number of algorithms are combined according to the industry pattern to develop an algorithm scheme for the industry and improve the operating efficiency and the operation security for clients. At present, more than 200 in dustry algorithm schemes have been released, covering more than 100 industry segments. For example, the operation compliance algorithm scheme is used to identify the compliance of outfit including safety helmet, uniform, insulated gloves and safety belt. Network: Through the mesh architecture, algorithms and scenario-based algorithm solutions are quickly assembled as needed in a flexible way. All algorithms are employed in a unified manner to realize intelligent cross-business integration. Take the big data service for cities as an example: Intelligent solutions and data of various business processes, such as water level management, sand mining vessel monitoring, urban construction management and fireworks monitoring, are integrated on a unified digital intelligence empowerment platform, and various algorithms are employed flexibly according to business requirements to realize the transformation from data intelligence to business intelligence. (2) Meet the needs of scenario-based AI solutions quickly and flexibly with the three modes of "quick customization by the Company", "convenient development by users" and "general algorithm paradigm" A four-tier technical system consisting of the Genius platform, operator components, general solutions, and industry solutions has been built to provide end-to-end customization and development capabilities for efficient scenario-based solutions and to accelerate the implementation of business intelligence at the industry level. Based on the open AI platform, clients can use their own data to develop their own scenario-based algorithms to accelerate business transformation and upgrade. Based on the rich experience in traditional image algorithms and deep learning algorithms and years of research efforts in innovative algorithm integration, the Company has proposed a general algorithm paradigm. The scenario-based intelligence can be achieved only by entering scenario-based data, with no need to re-train the model, so that more clients can put AI into use faster. (3) Achieve a qualitative leap in scenario-adapted capability of intelligent products and platforms through 20 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. the system architecture of "releasing an algorithm is to release a solution" To realize business intelligence, algorithm, product and platform need to be integrated to form a complete solution. The large number of fragmented and scenario-based AI requirements pose great challenges to the delivery cycle and the development cost of complete solutions, and have become a major obstacle in the actual implementation process of empowering enterprises and industries with AI. Based on the understanding of the industry application paradigm, the Company upgrades the algorithms, systems, applications and the software architecture of platforms, so that products and platforms can adapt themselves to algorithms without any customized development. Releasing an algorithm is to release a complete solution, which greatly shortens the development cycle and reduces the development cost. Since the model of customized development at manufacturers' end has changed to the model of on-demand configuration at clients' end, clients can select business modules freely based on specific requirements. (4) Make breakthroughs in small-target detection and tracking, single-model multi-tasking, end-to-end low-bit processing, se mi-supervised learning and weak supervision learning to solve scenario-based application challenges through continuous scientific research and innovation in industrial application based on the Genius platform With the development and popularization of high-definition imaging, multi-camera splicing, remote sensing and other technologies, the image resolution is getting higher and higher.

In the field of vision, the cost of computing power is still very high, and it is very important to control and reduce the cost of computing power. The Company adopts single-model multi-tasking and low-bit processing technologies to complete reasoning faster and more efficiently, greatly reducing the application cost of algorithms. Taking the vehicle recognition task as an example, the task which was originally completed by four models of detection, attribute, key point and recognition, now can be completed by one model. Combined with the end-to-end low-bit processing technology, the required computing power is reduced by 60%. Data scale directly affects the performance of deep learning algorithms. Through weak supervision and semi-supervised learning technologies, the Company reduces data dependence, decreases lab eling workload, and greatly improves development efficiency. For example, only 15% of the data need to be labeled for target segmentation of roads to achieve the same effect. In this field, the Company won the first prize in the category of "zero-sample target object recognition" in the 2021 Zhijiang Cup Global AI Competition. (5) Focus on the research of trusted AI technology considering the increasing challenges in data security and privacy protection In terms of precautions against attacks, the Company has designed networks and models with anti-attack capability by simulating attacks, analyzing network and model vulnerabilities, and adding the generated anti-attack samples to network training. In license plate recognition, the defense rate reaches 99%. In terms of privacy protection, the Company uses "non-reversible encryption" technology to effectively protect data privacy by removing sensitive information without affecting the intended effect of the algorithms. In terms of federated learning, the Company breaks down data silos and makes data available but invisible through distributed feature extraction and encryption training.

In order to reduce labor costs, many companies in the industry have invested in the R&D of automatic machine learning (AutoML). Based on the thorough research on AutoML and AI compiler, the Company, taking into consideration of its business characteristics, developed semi-automatic machine learning (SAML). SAML allows automatically selecting the optimal network and parameters from the experience library according to the algorithms, and fine-tunning them to adapt to the scenario. The computing power requirement and time consumption of AutoML are reduced to 1/1000 of the average level in the industry to achieve the same intended affect of algorithms, and 50% of the manpower is saved. This makes developing AI by AI possible. (2) Create an asse mbly line of data-driven algorithm sche mes through a sectionalized design based on ready-to-use models The Genius platform includes thousands of AI operators and pre-training models developed by the Company for various scenarios, which allows clients to plug and play with the components. By adopting the sectionalized design and low-code development mode, developers can create algorithm schemes by simply dragging the algorithms they need on a visualized interface to realize data-driven automatic algorithm iteration and one-click delivery of solutions. This greatly reduces the difficulty in use and improves efficiency by more than 40%. (3) Empower partners with the ability to industrialize AI at scale to achieve business success and mutual growth In this trend of digital transformation, many clients from different industries use AI to improve production efficiency. As AI industrialization represents a field with considerable opportunity, the Company should work together with its partners and clients to build an AI industrial ecosystem.

Our opinion on the financial statements does not cover the other information and we do not and will not express any form of assurance conclusion thereon. In combination with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit, or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard. V. Responsibilities of Management and Those Charged with Governance for the Financial Statements The Management is responsible for preparing the financial statements in accordance with the requirements of Accounting Standards for Business Enterprises to achieve a fair presentation, and for designing, implementing and maintaining necessary internal control to ensure that the financial statements are free from material misstatements, whether due to frauds or errors. In preparing the financial statements, the Management is responsible for assessing Dahua's ability to continue operating, disclosing matters related to continuous operation (if applicable) and using the hypothesis of continuous operation unless there is a plan to liquidate, terminate operations or no other realistic options. The management is responsible for supervising the financial reporting process of Dahua. VI. CPA's Responsibilities for the Audit of the Financial Statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an audit report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the audit standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users made 199 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. on the basis of these financial statements. As part of an audit in accordance with the audit standards, we exercise professional judgment and maintain professional skepticism throughout the audit. We also: (1) Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. (2) Obtain an understanding of internal control relevant to the audit in order to design appropriate audit procedures, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control. (3) Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the Management. (4) Conclude on the appropriateness of using the going concern assumption by the Management. At the same time, draw a conclusion, based on the audit evidence obtained, on whether there is significant uncertainty in matters or situations that may cause major doubts about Dahua's ability in continuous operation. If we conclude that a material uncertainty exists, we are required to draw attention in our audit report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the information available up to the date of our audit report. However, future events or conditions may result in Dahua's inability to continue operating. (5) Evaluate the overall presentation (including the disclosures), structure and content of the financial statements, and whether the financial statements fairly reflect the relevant transactions and events. (6) Obtain sufficient and appropriate audit evidence regarding the financial information of the entities or business activities within Dahua to express an opinion on the consolidated financial statements. We are responsible for guiding, supervising and implementing the group audit, and remain solely responsible for our audit opinion. We have communicated with those charged with governance on such matters as the scope of audit as planned, the schedule and material audit findings, including the defects in the internal control that are worth paying attention to found in this audit. We have also provided those charged with governance with a statement on observing the professional ethics related to independence, and communicated with those charged with governance on all the relationships and other matters that might be reasonably deemed to affect our independence, and relevant preventative measures. From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. We describe these matters in our audit report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so 200 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. would reasonably be expected to outweigh the public interest benefits of such communication.

The other overseas operating entities take the appropriate currency as the functional currency on the basis of the currency in the major economic environment in which they operate. This financial statement is presented in RMB. 5. The accounting treatment of business combinations involving enterprises under common control and business combinations not involving enterprises under common control Business combination involving entities under common control: The assets and liabilities acquired by the merging party in business combination (including goodwill incurred in the acquisition of the merged party by ultimate controlling party) shall be measured at the book value of the assets and liabilities of the merged party in the consolidated financial statements of the ultimate controlling party on the date of combination. The difference between the book value of the net assets obtained and the book value of the consideration paid for the combination (or total nominal value of the issued shares) is adjusted to capital premium in capital reserve. Adjustments shall be made to retained earnings in the event that the share premiums in the capital reserves are not sufficient for write-down. Business combination involving entities not under common control: The cost of combination is the fair value of the assets paid, the liabilities incurred or assumed, and the equity securities issued by the acquirer to acquire the control of the acquiree on the date of acquisition. Where the cost of combination is higher than the fair value of the identifiable net assets acquired from the merging party in business combination, such difference shall be recognized as goodwill; where the cost of combination is less than the fair value of the identifiable net assets acquired from the merging party in busines s combination, such difference shall be charged to the profit or loss for the period. The identifiable assets, liabilities and contingent liabilities of the acquiree obtained in the combination that satisfy the recognition criteria shall be measured by the fair value on the date of acquisition. The fees which are directly related to the business combination shall be recognized as the profit or loss in the period when the costs are incurred; the transaction expenses of issuing equity securities or debt securities for business merger shall be initially capitalized for equity securities or debt securities. 6. Preparation method of consolidated financial statements (1) Scope of Consolidation The scope of consolidation of the consolidated financial statements is based on controlling interests and includes the Company and all the subsidiaries. Control means that the Company has the power with respect to the investee to obtain variable returns by engaging in relevant activities of the investee, and has the ability to influence the amount of its returns by applying its power with respect to the investee. (2) Procedures of Consolidation The Company will treat the enterprise group as a single accounting entity and prepare the consolidated financial statements in accordance with the unified accounting policy to reflect the Group's ov erall financial position, operating results and cash flow. The influence from the internal transactions between the Company and the subsidiaries or between different subsidiaries shall be eliminated. Internal transactions show that impairment loss of relevant assets shall be recognized as such loss in full. In preparing the consolidated financial statements, where the accounting policies and the accounting periods are inconsistent between the Company and subsidiaries, the financial statements of subsidiaries are adjusted in accordance with the accounting policies and accounting period of the Company. The owner's equity, the net profit or loss and the comprehensive income attributable to minority shareholders of a 230 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. subsidiary of the current period are presented separately under the owners' equity in the consolidated balance sheet, the net profit and the total comprehensive income in the consolidated income statement respectively. Where losses attributable to the minority shareholders of a subsidiary of the current period exceed the minority shareholders' interest entitled in the shareholders' equity of the subsidiary at the beginning of the period, the excess is allocated against the minority shareholders interest. ① Acquisition of Subsidiaries or Business For acquisition of subsidiaries or business due to business combination involving entities under common control during the reporting period, the operating results and cash flow of such subsidiaries or business from the beginning to the end of the reporting period when the merger occurs are included in the consolidated income statement; and the opening balance and comparative figures of the consolidated financial statements should be adjusted simultaneously as if the consolidated reporting entity has been in existence since the beginning of the control by the ultimate controlling party. In connection with imposing control over the investee under common control due to additional investment and other reasons, the equity investment held before gaining the control of the combined party is recognized as relevant profit or loss, other comprehensive income and changes in other net assets at the later of the date of acquisition of the original equity and the date when the combining and the combined parties are under common control, and shall be written down to the opening balance retained earnings or current profit or loss in the comparative reporting period. Additional subsidiaries or business due to business combination involving entities not under common control during t he reporting period will be included in the consolidated financial statements as of the date of acquisition on the basis of the fair value of the identifiable assets, liabilities or contingent liabilities determined on the date of acquisition. In connection with imposing control over the investee not under common control due to additional investment and other reasons, the equity of acquiree held before acquisition date shall be remeasured at the fair value of such equity on the acquisition date and the difference between fair value and book value shall be recognized as investment income in current period. Other comprehensive income that may later be reclassified into profit or loss and changes in other owner's equity accounted by equity method contained in the acquiree's equity held before the acquisition date shall be transferred to current investment gains on the date of acquisition. ② Disposal of Subsidiaries or Business a. General Treatment When losing control of the investee due to partial disposal of the equity investment, or any other reasons, the remaining equity investment is remeasured at fair value at the date in which control is lost. The sum of consideration received from disposal of equity investment and the fair value of the remaining equity investment, net of the difference between the sum of the Company's previous share of the subsidiary's net assets recorded from the acquisition date or combination date and the sum of goodwill, is recognized in investment income in the period in which control is lost. Other comprehensive income that may later be reclassified into profit or loss and changes in other owner's equity accounted by equity method in connection with the equity investment of the original subsidiaries shall be transferred to the current investment gains when the control is lost. b. Disposal of Subsidiary Achieved by Stages When the equity investment of subsidiaries is disposed of through multiple transactions until the control is lost, such multiple transactions are generally treated as a package deal if the terms, conditions and economic impact of the transactions to dispose of the subsidiary's equity investment satisfy one or more of the following conditions: ⅰ. These transactions are achieved at the same time or the mutual effects on each other are considered; ⅱ. A complete set of commercial results can be achieved with reference to the series of transactions as a whole; ⅲ. Achieving a transaction depends on at least achieving of one of the other transactions; ⅳ. One transaction recognized separately is not economical, but it is economical when considered together with other transactions. 231 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. If multiple transactions are recognized as a package deal, these transactions shall be subject to accounting treatment as a transaction to dispose of the subsidiaries and lose control. The differences between the price on each disposal and disposal of investment on the subsidiary's net assets shall be recognized in other comprehensive income in the consolidated financial statements, and included in profit or loss for the period when the control is lost. If the transactions are not a package deal, accounting treatment for partial disposal of equity investments of the subsidiary without losing control shall be applied before control is lost. When the control is lost, general accounting treatment for disposal of a subsidiary shall be used. ③ Acquisition of Minority Interest of Subsidiaries The Company shall adjust the share premium in the capital reserve of the consolidated balance sheet with respect to any difference between the long-term equity investment arising from the purchase of minority interest and the net assets attributing to the parent company continuously calculated on the basis of the newly increased share proportion as of the acquisition date or date of combination or, adjust the retained earnings if the share premium in the capital reserve is insufficient for write-down. ④ Partial Disposal of Equity Investment in Subsidiaries without Losing Control The difference between the disposal consideration and the share of net assets in the subsidiaries calculated from disposal of long-term equity investment as of the date of acquisition or combination date shall be adjusted to share premium in the capital reserve in the consolidated balance sheet. Adjustments shall be made to retained earnings in the event that the share premiums in the capital reserves are not sufficient for write-down. 7. Classification of joint venture arrangement and accounting treatment methods for joint operation Joint venture arrangement is classified into joint operation and joint venture. Joint operation means the joint venture arrangement in which the joint venture parties have the assets and assume the liabilities related to such arrangement. The Company recognizes the following items related to the share of interests in the joint operation: (1) The assets separately held by the Company and assets jointly held as recognized by the share of the Company; (2) The liabilities separately assumed by the Company and liabilities jointly assumed as recognized by the share of the Company; (3) Income from selling the share of the Company in the output of the joint operation; (4) Income from joint operation of the sold output as recognized by the share of the Company; (5) The expenses separately incurred and expenses jointly incurred as recognized by the share of the Company; The Company adopts the equity method for the investment of the joint venture. For details, refer to this section Financial Report - (V) Significant Accounting Polices and Accounting Estimates - 19. Long-term equity investment. 8. Recognition criteria of cash and cash equivalents Cash means the cash on hand and deposits that are available for payment at any time of the Company. Cash equivalents mean the investments held by the Company which are short-term, highly liquid, easy to be converted into known amounts of cash and have little risk of value change. 9. Conversion of transactions and financial statements denominated in foreign currencies (1) Foreign currency transactions Foreign currency transactions shall be translated into RMB at the spot exchange rate on the day when the transactions 232 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. occurred. Balance sheet date foreign currency monetary items shall be translated using the spot exchange rate at the balance sheet date. The resulting exchange differences are recognized in profit or loss for the current period, except for those differences related to the principal and interest on a specific-purpose borrowing denominated in foreign currency for acquisitions, construction or production of the qualified assets, which should be capitalized as cost of the assets. 2. Translation of foreign currency financial statements All assets and liabilities items in balance sheet are translated based on spot exchange rate on the balance sheet date; owners' equity items other than "undistributed profit" are translated at a spot exchange rate when accrued. Revenue and expense items in the income statement are translated at a spot exchange rate at the transaction occurrence date. For disposal of overseas operation, the translation difference as stated in the foreign currency financial statements relating to overseas operation, is accounted for in the profit and loss account in the current period from owners' equity items. 10. Financial instruments A financial asset, financial liability or equity instrument is recognized when the Company becomes a party to the financial instrument contract. (1) Classification of the financial instruments According to the Company's business model for management of the financial assets and the contractual cash flow features of the financial assets, the financial assets, when initially recognized, are classified as: financial assets at amortized cost, financial assets at fair value through other comprehensive income (debt instruments) and financial assets at fair value through profit or loss. The financial assets which satisfy the following conditions, and are not designated as financial assets at fair value through profit or loss will be classified by the Company as financial assets at amortized cost: - The business model is designed to collect the contractual cash flow; - The contractual cash flow is only used to pay the principal and the interests based on the outstanding principal amount. The financial assets which satisfy the following conditions, and are not designated as financial assets at fair value through profit or loss will be classified by the Company as the financial assets (equity instruments) at fair value through other comprehensive income: - The business model is designed to both collect the contractual cash flow and sell the financial assets; - The contractual cash flow is only used to pay the principal and the interests based on the outstanding principal amount. For non-trading investments in equity instruments, the Company may, at the time of initial recognition, irrevocably designate them as financial assets (equity instruments) at fair value through other comprehensive income. Such designation is based on the individual investments, and relevant investments fall within the definition of the equity instrument from the perspective of the issuer. Except for the financial assets at amortized cost, and financial assets at fair value through other comprehensive income, all the remaining financial assets are classified as the financial assets at fair value through profit or loss. At the time of initial recognition, the financial assets which should have been classified as financial assets at amortized cost or financial assets at fair value through other comprehensive income can be irrevocably designated by the Company as financial assets at fair value through profit or loss if the accounting mismatch can be eliminated or significantly reduced. The financial liabilities, when initially recognized, are classified as: financial liabilities at fair value through profit or loss and financial liabilities at amortized cost. 233 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. Financial liabilities which meet one of the following conditions will be, when initially measured, designated as financial liabilities at fair value through profit or loss: 1) Such designation may be able to eliminate or significantly reduce the accounting mismatch. 2) The portfolio of financial liabilities or the portfolio of financial assets and financial liabilities shall be subject to management and performance evaluation on the basis of fair value according to the enterprise risk management or investment strategy contained in the formal documentations, and a report shall be made to the key management personnel within the enterprise on this basis. 3) Such financial liabilities shall contain embedded derivatives to be split separately. Subject to the conditions above, the Company has no such designated financial liabilities. (2) Recognition and measurement of financial instruments ① Financial assets at amortized cost Financial assets at amortized cost include notes receivable, accounts receivable, other receivables, long-term receivables and creditors investment, which shall be initially measured at fair value, and the relevant transaction e xpenses should be initially capitalized; The accounts receivable that do not contain material financing compositions and those for which the Company decides to not take into account the financing compositions of no more than one year shall be initially measured at the contract transaction price. The interest calculated by effective interest rate method during the holding period is recorded into the current profit and loss. At the time of recovery or disposal, the difference between the price obtained and the book value shall be included in the current profit or loss. ② Financial assets measured at fair value and its changes are included in other comprehensive income (debt instruments) Financial assets measured at fair value and its changes are included in other comprehensive income (debt instruments) include receivables financing and investments in other creditor's rights. They are initially measured at fair value, and the relevant transaction expenses should be initially capitalized. These financial assets are subsequently measured at fair value, and the change in fair value, other than the interest, the impairment loss or profit and the profit or loss on foreign exchange, shall be included in other comprehensive income. Upon derecognition, the cumulative profits or losses previously included in other comprehensive income shall be removed from other comprehensive income and included in the profit or loss for the period. ③ Financial assets at fair value through other comprehensive income (equity instruments) Financial assets at fair value through other comprehensive income (equity instruments) include investment in other equity instruments. They are initially measured at fair value, and the transaction expenses shall be initially capitalized. These financial assets are subsequently measured at fair value, and the change in fair value shall be included in other comprehensive income. The dividends obtained shall be included in the profit or loss for the period. Upon derecognition, the cumulative profits or losses previously included in other comprehensive income shall be removed from other comprehensive income and included in the carry-forward retained earnings. ④ Financial assets at fair value through profit or loss Financial assets at fair value through profit or loss include trading financial assets, derivative financial assets and other non-current financial assets. They are initially measured at fair value, and the transaction expenses related to them are included in the profit or loss for the period. These financial assets are subsequently measured at fair value, and the change in fair value shall be included in the profit or loss for the period. ⑤ Financial liabilities at fair value through profit or loss Financial liabilities at fair value through profit or loss include trading financial liabilities and derivative financial liabili ties. They are initially measured at fair value, and the transaction expenses related to them are included in the profit or loss for 234 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. the period. These financial liabilities are subsequently measured at fair value, and the change in fair value shall be included in the profit or loss for the period. Upon derecognition, the difference between their book value and the consideration pai d is included in the profit or loss for the period. ⑥ Financial liabilities at amortized cost Financial liabilities at amortized cost include short-term loans, notes payable, accounts payable, other payables, long-term loans, bonds payable, and long-term payables. They are initially measured at fair value, and the transaction expenses shall be initially capitalized. The interest calculated by effective interest rate method during the holding period is recorded into the current profit and loss. Upon derecognition the difference between the consideration paid and the book value of these financial liabilities is included in the current profit or loss. (3) Derecognition and transfer of financial assets When one of the following conditions is met, financial assets are derecognized by the Company: - The contractual right to receive cash flows from financial assets is terminated; - The financial assets have been transferred and nearly all the risks and rewards related to the ownership of the financial assets have been transferred to the transferee; - The financial assets have been transferred and although the Company neither transfers or retains all the risks and rewards related to the ownership of the financial assets, the Company retains no control of the financ ial assets; The financial assets when transferred will not be derecognized if the Company has retained nearly all the risks and rewards related to the ownership of the financial assets. The substance-over-form principle shall be adopted while making judgment on whether the transfer of financial assets satisfies the above conditions for termination of recognition. The transfer of financial assets can be classified into entire transfer and partial transfer. If the transfer of an entire fi nancial asset satisfies the conditions for termination of recognition, the difference between the two amounts below shall be recorded into profit or loss for the period: ① The book value of the financial asset transferred; ② The consideration received as a result of the transfer, plus the accumulative amount of the change in fair value previously recorded into the owners' equity (in cases where the transferred financial assets are financial assets at fair value through other comprehensive income (debt instruments)). If the partial transfer of financial assets satisfies the conditions for termination of recognition, the overall book value of the transferred financial asset shall be apportioned according to their respective relative fair value between the recognition terminated part and the remaining part, and the difference between the two amounts below shall be recorded into profit or loss for the current period: ① The book value of the recognition terminated portion; ② The sum of consideration of the derecognized portion and the corresponding portion of accumulated change in fair value previously recorded into owners' equity (in cases where the transferred financial assets are financial assets at fair value through other comprehensive income (debt instruments)). Financial assets will still be recognized if they fail to satisfy the conditions for termination of recognition, with the consideration received recognized as a financial liability. (4) Derecognition of financial liabilities When the current obligation under a financial liability is completely or partially discharged, the recognition of the whole or relevant portion of the liability is terminated; an agreement is entered between the Company and a creditor to replace the original financial liabilities with new financial liabilities with substantially different terms, terminate the recognition o f the 235 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. original financial liabilities as well as recognize the new financial liabilities. If all or part of the contract terms of the original financial liabilities are substantially amended, the recognition of the original financial liabilities will be terminated in full or in part, and the financial liabilities whose terms have been amended shall be recognized as a new financial liability. When recognition of financial liabilities is terminated in full or in part, the difference between the book value of the financial liabilities terminated and the consideration paid (including transferred non-cash assets or new financial liability) is recognized in profit or loss for the current period. Where the Company repurchases part of its financial liabilities, the book value of such financial liabilities will be allocat ed according to the relative fair value between the continued recognized part and terminated part on the repurchase date. The difference between the book value of the financial liabilities terminated and the consideration paid (including transferred non-cash assets or new financial liability) is recognized in profit or loss for the current period. (5) Method of determining the fair values of financial assets and liabilities The fair value of a financial instrument that is traded in an active market is determined at the quoted price in the active market. The fair value of a financial instrument that is not traded in an active market is determined by using a valuation technique. The Company uses the valuation technique when it is applicable under current conditions and there are enough available data and other information to support and the technique should maximize the use of relevant observable. It chooses the inputs which are consistent with the asset or liability's characteristics considered by market participants in the transaction of the relevant asset or liability and makes the maximum use of relevant observable inputs. Unobservable inputs are used under the circumstance that the relevant observable inputs cannot be obtained or not feasible. (6) Test method and accounting treatment for impairment of financial assets The Company estimates the expected credit loss on the financial assets at amortized cost, the financial assets at fair value through other comprehensive income (debt instruments), and the financial guarantee contracts, either alone or in combination. Taking into the reasonable and well-grounded information including past matters, current situation and prediction of future economic conditions, the Company calculates the possibly weighted amount of the present value of the difference between the cash flows receivable under the contract and the cash flows expected to be received, taking the risk of default as the weight, and recognizes the expected credit loss . If the credit risk of this financial instrument has been significantly increased upon initial recognition, the Company measures its loss provision in accordance with the amount equivalent to the expected credit loss of the financial instrument throughout the duration; if the credit risk of this financial instrument is not significantly increased upon initi al recognition, the Company will measure the loss provision of this financial instrument by the amount of its expected credit loss in the 12 months to come. The increased or reversed amount of the loss provision resulting therefrom is included in the current profit or loss as the impairment loss or profit. By comparing the risk of default of financial instruments on the balance sheet date with the risk of default on the initial recognition date, the Company determines the relative change in the risk of default over the expected life of financial instruments to assess whether the credit risk of financial instruments has increased significantly since initial recognition. If the financial instrument becomes overdue for more than 30 days, the Company believes that the credit risk of this financial instrument has been significantly increased, unless there are concrete evidences that the credit risk of this financial instrument has not been significantly increased upon initial recognition. If the financial instrument carries low credit risk at the balance sheet date, the Company believes that the credit risk of this financial instrument is not significantly increased upon initial recognition. If there are objective evidences showing that a certain financial asset has been subject to credit impairment, the Company will accrue impairment provision for this financial asset on the individual asset basis. The Company will always measure the loss provision for the accounts receivable and contract assets arising from the 236 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. transactions regulated by "Accounting Standard for Business Enterprises No.14 — Revenue" (2017), whether they contain material financing compositions or not, by the amount of the expected credit loss throughout the duration. For the lease receivables, the Company will always measure the loss provision for the accounts receivable, by the amount of the expected credit loss throughout the duration. If the Company no longer reasonably expects that the cash flow of the financial asset contract can be recovered as a whole or in part, the book balance of such financial assets will be directly reduced. 11.

Inventories (1) Category of inventory Inventories are classified as raw materials, commodity stocks, products in progress and materials commissioned for processing. The inventories are initially measured at cost, which comprises the cost of purchase, cost of conversion and other expenditure incurred in bringing the inventories to their present location and condition. (2) Determination of cost Cost of inventories is determined using the weighted average method. (3) Basis for the determination of net realizable value and different type of inventories At the balance sheet date, inventories are measured at the lower of cost and net realizable value. When the cost of inventories is higher than their net realizable value, reserve for stock d epreciation shall be accrued. The net realizable value means the amount after deducting the estimated cost of completion, estimated selling expenses and relevant taxes from the estimated selling price of inventories in the daily activities. Net realizable value of held-for-sale commodity stocks, such as finished goods, goods-in-stock, and held-for-sale raw materials, during the normal course of production and operation, shall be determined by their estimated sales less the related selling expenses and taxes; the net realizable value of material inventories, which need to be processed, during 237 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. the normal course of production and operation, shall be determined by the amount after deducting the estimated cost of completion, estimated selling expenses and relevant taxes from the estimated selling price of finished goods; the net realizable value of inventories held for execution of sales contracts or labor contracts shall be calculated on the ground of the contracted price. If an enterprise holds more inventories than the quantity stipulated in the sales contract, the net realizable value of the exceeding part shall be calculated on the ground of general selling price. If the factors influencing the write-down of the inventory value have disappeared, resulting in higher net realizable value of inventories than their book value after the reserve for stock depreciation is accrued, a reversal shall apply in the amount of reserve for stock depreciation previously accrued, and the reserved amount shall be included in th e current profit or loss. (4) Inventory system The perpetual inventory system is adopted. (5) Amortization of low-value consumables and packaging materials ① Low-value consumables are amortized using the immediate write-off method; ② Packaging materials are amortized using the immediate write-off method. 16. Contract assets (1) Recognition method and criteria of contract assets The Company lists contract assets or contract liabilities in the balance sheet according to the relationship between performance obligations and customer payments. Considerations that the Company has the right to collect for commodities transferred or services provided to customers (and such right depends on other factors than passing of time) are presented as contract assets. The contract assets and contract liabilities under the same contract are presented in net amount. The Company separately presents the right possessed to collect consideration from customers unconditionally (only depending on the passing of time) as accounts receivable. (2) Determination method and accounting treatment method for the expected credit loss of contract assets For the determination method and accounting treatment method for the expected credit loss of contract assets, refer to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 10. Financial instruments. 17. Contract costs The contract costs comprise the contract performance cost and the cost to obtain a contract. The costs incurred by the Company for contract performance which fall outside the scope of the enterprise accounting standards such as inventories, fixed assets or intangible assets will be identified as an asset of the contract performance costs upon satisfying all of the following conditions: The costs are directly related to one existing contract or one contract that is expected to be obtained. The costs enrich the Company's resources for future contract performance. The costs are estimated to be recovered. The incremental costs which are incurred by the Company to obtain the contract and are expected to be recovered will be identified as an asset of the costs to obtain a contract. The assets related to the contract costs will be amortized on the same basis for recognition of the income from commodities or services related to the assets; but if the amortization period of the costs to obtain the contract is no more than 1 year, the Company will include such costs in the current profit or loss once occurred. In case that the book value of assets related to contract costs is higher than the difference between the two items below, the Company will accrue the impairment provision for the extra part, and recognize that part as impairment loss: (1) Estimated residual consideration to be obtained from transfer of commodities or services related to the assets; (2) Estimated costs incurred from transfer of relevant commodities or services. 238 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. If the factors for impairment in the previous periods are subsequently changed, making the aforesaid difference highe r than the book value of the assets, the Company will reverse the accrued impairment provision and include it in the current profit or loss, provided that the book value of the reversed assets does not exceed the book value of the assets without impairment provision accrued on such date of reversal. 18. Holding assets for sale An asset of which the book value is recovered mainly through sale (including exchange of non-monetary asset of a commercial nature) rather than non-continuous use of a non-current asset or disposal group is classified as a holding asset for sale. A non-current asset or disposed group is classified by the Company as holding for sale if it meets the following criteria at the same time: (1) Immediate sale could be made under the current circumstances in accordance with the convention of selling such kind of assets or disposal groups in similar transactions; (2) Selling is extremely likely to occur, i.e. the Company has made a resolution on a selling plan and obtained confirmed purchase commitments, and the selling is predicted to be completed within 1 year. If required by relevant provisions that selling shall only be made after approved by the relevant competent authority or supervision department of the Company, such approval should have been obtained. If the book value of the non-current assets (excluding financial assets, deferred income tax assets, and assets to constitute payroll payable) or disposal groups classified as holding for-sale assets is higher than the net amount after deducting the selling expenses from the book value, the book value will be written down to the net amount after deducting the selling expenses from the fair value, and the amount written down will be recognized as the impairment loss of assets and included in the current profit or loss. At the same time, the impairment provision for holding for-sale assets will be accrued. 19. Long-term equity investment (1) Joint control or significant influence criterion Joint control is the contractually agreed sharing of control of an arrangement, and exists only when requiring the unanimous consent of the parties sharing control before making decisions about the relevant activities of the arrangement. The Company together with the other joint venture parties can jointly control over the investee and are entitled to the right of the net assets of the investee, as the investee is joint venture of the Company. Significant influence refers to the power to participate in making decisions on the financial and operating policies of an enterprise, but not the power to control, or jointly control, the formulation of such policies with other parties. Where the Company can exercise significant influence over the investee, the investee is an associate of the Company. (2) Determination of initial investment cost ① Long-term equity investments formed through business combination of entities For the long-term equity investment in the subsidiaries arising from business combination involving entities under common control, the initial investment cost of the long-term equity investment is the share with reference to the book value of the shareholders' equity of the combined party in the consolidated financial statements of the ultimate controlling party on the date of combination. The share premium in the capital reserve shall be adjusted according to the difference between the initial investment cost of the long-term equity investment and the carrying amount of the consideration paid; if the share premium in the capital reserve is insufficient to offset, the retained earnings shall be adjusted. In connection with imposing control over the investee under common control as a result of additional investment and other reasons, the share premium shall be adjusted according to the difference between the initial investment cost of the long-term equity 239 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. investment as recognized by the above principle and the carrying value of the long-term equity investment before combination and the sum of carrying value of newly paid consideration for additional shares acquired on the date of combination. If the share premium is insufficient for write-down, the retained earnings shall be offset. For the long-term equity investment in the subsidiaries arising from business combinations involving entities not under common control, the cost of the combination ascertained on the date of acquisition shall be taken as the initial investment cost of the long-term equity investment. In connection with imposing control over the investee not under common control as a result of additional investment and other reasons, the initial investment cost shall be the sum of the book value of the equity investment originally held and the newly increased initial investment cost. ② Long-term equity investments acquired by the means other than business combination The initial cost of a long-term equity investment obtained by cash payment shall be the purchase costs actually paid. The initial cost of investment of a long-term equity investment obtained by means of issuance of equity securities shall be the fair value of the equity securities issued. (3) Subsequent measurement and recognition of profit or loss ① Long-term equity investment calculated by cost method Long-term equity investment in subsidiaries of the Company is calculated by cost method, unless the investment meets the conditions for holding for sale. except for the actual consideration paid for the acquisition of investment or the declar ed but not yet distributed cash dividends or profits which are included in the consideration, investment gains are recognized as the Company' shares of the cash dividends or profits declared by the investee. ② Long-term equity investment accounted for by equity method Long-term equity investments of associates and jointly controlled entities are calculated using equity method. Where the initial investment cost of the long-term equity investment exceeds the investor's interest in the fair value of the investee's identifiable net assets at the acquisition date, no adjustment shall be made to the initial investment cost; where the initial investment cost is less than the investor's interest in the fair value of the investee's identifiable net assets at the acquisition date, the difference shall be charged to the profit or loss for the current period. At the same time, the cost of the long-term equity investment shall be adjusted. The Company recognizes the investment income and other comprehensive income according to the shares of net profit or loss and other comprehensive income realized by the investee which it shall be entitled or shared respectively, and simultaneously makes adjustment to the book value of long-term equity investment; The book value of long-term equity investment shall be reduced by attributable share of the profit or cash dividends for distribution declared by the investee. In relation to other changes in the owner's equity except for net profits and losses, other comprehensive income and profit distributions of the investee (hereinafter referred to as “Changes in Other Owner's Equity”), the book value of the long-term equity investment shall be adjusted and included in owner's equity. When determining the amount of proportion of net profit or loss, other comprehensive income and other changes in the owner's equity in the investee which it entitles, the fair value of each identifiable assets of the investee at the time when the investment is obtained shall be used as basis, and according to the accounting policies and accounting period of the Company, adjustment shall be made to the net profit and other comprehensive income of the investee. The unrealized profit or loss resulting from transactions between the Company and its associates or joint venture shall be eliminated in proportion to the investor's equity interest of investee, based on which investment income or loss shall be recognized, except for those assets invested or sold constituting a business. Any losses resulting from transactions, which are attributable to impairment of assets, shall be fully recognized. The net loss incurred by the Company to the joint ventures or affiliates is capped when the carrying amount of long-term equity investment and the long-term equity that substantially constitutes the net investment in the joint ventures or affiliates have been wrote down to zero, except to the extent that the Company has an additional loss obligation. If the joint ventures or affiliates later realize net profit, the Company will resume recognition of the income share after the income 240 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. share makes up the unrecognized loss share. ③ Disposal of long-term equity investments For disposal of long-term equity investment, the difference between the book value and the consideration actually received shall be included in the current profit or loss. If the remaining equity is still subject to the equity method in partial disposal of the long-term equity investment under the equity method, other comprehensive income recognized in the original equity investment shall be carried forw ard at the appropriate proportion on the same basis used by the investee for direct disposal of relevant assets or liabilities, and other changes in the owner's equity shall be carried forward into the current profit or loss at the appropriate proportion. When losing the control or material influence over the investee due to disposal of the equity investment and other reasons, other comprehensive income recognized in the original equity investment due to adoption of the equity method shall be subject to accounting treatment on the same basis used by the investee for direct disposal of relevant assets or liabilities when ceasing to use the equity method, and other changes in the owner's equity shall be carried forward into the current profit or loss in full when ceasing to use the equity method. If the control over the investee is lost due to partial disposal of the equity investment and other reasons, and if the remaining equities can exercise common control or material influence over the investee in prep aring the individual financial statements, the remaining equities shall be accounted by the equity method and shall be adjusted as if such remaining equities have been accounted for under the equity method since they are obtained. Other comprehensive income recognized before the control over the investee is obtained shall be carried forward pro rata on the same basis used by the investee for direct disposal of relevant assets or liabilities, and other changes in the owner's equity recognized under the equity method shall be carried forward into the current profit or loss pro rata. The remaining equities which cannot exercise common control or material influence over the investee shall be recognized as financial assets, and the difference between their fair value and book value on the date when the control is lost shall be included in the current profit or loss. Other comprehensive income recognized and other changes in the owner's equity recognized before the control over the investee is obtained shall be carried forward in full. If the disposal of the equity investment in the subsidiaries through multiple transactions until loss of the control is a package deal, each transaction shall be subject to accounting treatment as a transaction to dispose of the equity investment in the subsidiaries and to lose the control; the difference between the price for each disposal before loss of the control and the book value of the long-term equity investment of the equity disposed of shall be first recognized as other comprehensive income in the individual financial statements and shall then be carried forward to the profit or loss for the very period when the control is lost. If it is not a package deal, each transaction shall be subject to accounting treatment. 20. Investment property Investment property refers to the real estate held to generate rental income or capital appreciation, or both, including leased land use rights, land use rights held for transfer after appreciation, and leased buildings (including buildings that are leased after completion of self-construction or development activities and buildings in construction or development that are used for rental in the future). The Company adopts the cost mode to measure the existing investment property. The subsequent expenditure related to the investment property will be included in the cost of the investment property when relevant economic benefits are likely to flow in and costs can be measured reliably, or otherwise be included in the current profit or loss whe n occurred. Investment property measured at cost - buildings held for leasing shall adopt the same depreciation policy for fixed assets of the company, land use rights held for leasing shall adopt the same amortization policy for the intangible assets. 241 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. 21. Fixed assets (1) Conditions for recognition of fixed assets Fixed assets are tangible assets that are held for use in the production or supply of goods or services, for rental to others , or for administrative purposes; and have a service life of more than one accounting year. Fixed asset is recognized when it meets the following conditions: ① It is probable that the economic benefits associated with the fixed asset will flow to the enterprise; ② Its cost can be reliably measured. The fixed assets are initially measured at cost (with the impact of predicted discard expense taken into account). The subsequent expenditure related to the fixed assets will be included in the cost of the fixed assets when the economic benefits in connection therewith are likely to flow in and costs can be measured reliably; the book value of the replaced part will be derecognized; all other subsequent expenditure will be included in the current profit or loss when occurred. (2) Methods for depreciation Category Depreciation method Useful lives of depreciation Residual Ratio Annual depreciation rate Housing and building Straight-line method 20 5% 4.75% Machinery and Straight-line method 5-10 5% 19.00%-9.50% equipment Means of transport Straight-line method 4-8 5% 23.75%-11.88% Electronic and other Straight-line method 3-5 5% 31.67%-19.00% equipment Fixed assets are depreciated by categories using the straight-line method, and the annual depreciation rates are determined by categories based upon their estimated useful lives and their estimated residual values. Where the parts of a fixed asset have different useful lives or cause economic benefits for the enterprise in different ways, different depreciation rates or depreciation methods shall apply, and each part is depreciated separately. (3) Disposal of fixed assets When fixed assets are disposed of or when no economic benefits can be expected through use or disposal thereof, such fixed assets will be derecognized. The income from disposal of the fixed assets through sale, transfer, scrapping or damage with the book value thereof and relevant taxes deducted is included in the current profit or loss. 22. Projects under construction The projects under construction are measured at the actual cost. The actual cost comprises the building cost, installation cost, borrowing cost qualified for capitalization and other necessary expenditures incurred to bring the projects under construction to the conditions before they are made ready for the intended use. The projects under construction will be converted into fixed assets when they are ready for intended use and will be depreciated from the next month on. 23. Borrowing costs (1) Criteria for recognition of capitalized borrowing costs 242 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. For borrowing costs incurred by the Company that are directly attributable to the acquisition, construction or production of assets qualified for capitalization, the costs will be capitalized and included in the costs of the related assets. Other borrowing costs shall be recognized as expense in the period in which they are incurred and included in profit or loss for the current period. Assets qualified for capitalization are assets (fixed assets, investment property, inventories, etc.) that necessarily take a substantial period of time for acquisition, construction or production to get ready for their intended use or sale. (2) Capitalization period of borrowing costs The capitalization period shall refer to the period between the commencement and the cessation of capitalization of borrowing costs, excluding the period in which capitalization of borrowing costs is temporarily suspended. Capitalization of borrowing costs begins when the following three conditions are fully satisfied: ① expenditures for the assets (including cash paid, transferred non-currency assets or expenditure for holding debt liability for the acquisition, construction or production of assets qualified for capitalization) have been incurred; ② borrowing costs have been incurred; ③ acquisition, construction or production that are necessary to enable the asset reach its intended usable or salable condition have commenced. Capitalization of borrowing costs shall be suspended during periods in which the qualifying asset under acquisition and construction or production ready for the intended use or sale. (3) Suspension of capitalization period Capitalization of borrowing costs shall be suspended during periods in which the acquisition, construction or production of a qualifying asset is interrupted abnormally, when the interruption is for a continuous period of more than 3 months; if the interruption is a necessary step for making the qualifying asset under acquisition and construction or production ready for the intended use or sale, the capitalization of the borrowing costs shall continue. The borrowing costs incurred during such period shall be recognized as profits and losses of the current period. When the acquisition and construction or production of the asset resumes, the capitalization of borrowing costs commences. (4) Calculation of capitalization rate and amount of borrowing costs Specific borrowings for the acquisition, construction or production of assets qualified for capitalization, borrowing costs of the specific borrowings actually incurred in the current period minus the interest income earned on the unused borrowing loans as a deposit in the bank or as investment income earned from temporary investment will be used to determine the amount of borrowing costs for capitalization. General borrowings for the acquisition, construction or production of assets qualified for capitalization, the to-be-capitalized amount of interests on the general borrowing shall be calculated and determined by multiplying the weighted average asset disbursement of the part of the accumulative asset disbursements minus the specifically borrowed loans by the capitalization rate of the general borrowing used. The capitalization rate shall be calculated and determined according to the weighted average interest rate of the general borrowing. During the capitalization, the difference between the principal and interest of special borrowings in foreign currency shall be capitalized and included in the cost of assets qualified for capitalization. The difference between the principal and interest of the borrowings in foreign currency other than the special borrowings in foreign currency shall be included in the current profit or loss. 24. Intangible assets (1) Valuation method of intangible assets ① Intangible assets are initially measured at cost upon acquisition The costs of an externally purchased intangible asset include the purchase price, relevant taxes and expenses paid, 243 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. and other expenditures directly attributable to putting the asset into condition for its intended use. ② Subsequent measurement The service life of intangible assets shall be analyzed and judged upon acquisition. As for intangible assets with a finite service life, they are amortized using the straight-line method over the term in which economic benefits are brought to the firm; If the term in which economic benefits are brought to the firm by an intangible asset cannot be estimated, the intangible asset shall be taken as an intangible asset with indefinite service life, and shall not be amortized. (2) Estimation of service life of the intangible assets with limited service life Item Estimated useful lives Basis Land use rights 40 or 50 years Land use certificate Non-patented technology 5-10 years Expected benefited period Softwares 2-5 years Expected benefited period Trademark rights 6 years Expected benefited period Software copyright 10 years Expected benefited period For an intangible asset with a finite service life, review on its service life and amortization method is performed at the end of each end. Upon review, service life and amortization method for the intangible assets are the same with the previous estimate at the end of this period. (3) The basis for the judgment of intangible assets with uncertain service life and the procedure for reviewing their service life As at the balance sheet date, the Company has no intangible assets with uncertain service life. (4) Specific criteria for the division of research phase and development phase The expenses for internal research and development projects of the Company are divided into expenses in the research phase and expenses in the development phase. Research phase: Scheduled innovative investigations and research activities to obtain and understand scientific or technological knowledge. Development phase: Apply the research outcomes or other knowledge to a plan or design prior to a commercial production or use in order to produce new or essentially-improved materials, devices, products, etc. (5) Specific condition for capitalizing expenditure during the development phase Expenses in the research phase are recorded into the profits and losses for the current period when they occur. The expenses in the development phase are recognized as intangible assets if the following conditions are fulfilled, and are included in the current profit or loss if following conditions are not fulfilled: ①It is technically feasible to complete such intangible asset so that it will be available for use or for sale; ②There is intention to complete the intangible asset for use or sale; ③The intangible asset can produce economic benefits, including there is evidence that the products produced using the intangible asset has a market or the intangible asset itself has a market; if the intangible asset is for internal use, there is evidence that there exists usage for the intangible asset; ④There is sufficient support in terms of technology, financial resources and other resources in order to complete the development of the intangible asset, and there is capability to use or sell the intangible asset; ⑤The expenses attributable to the development stage of the intangible asset can be measured reliably. If the expenses in the research phase and expenses in the development phase cannot be distinguished, all the 244 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. expenses incurred for R&D are included in the current profit or loss. 25. Impairment of long-term assets Long-term assets, such as long-term equity investment, investment properties that are measured at cost, fixed assets, construction in progress, intangible assets with limited service life and oil and gas assets are tested for impairment if there is any indication that an asset may be impaired at the balance sheet date. If the result of the impairment test indicates that the recoverable amount of the asset is less than its book value, a provision for impairment and an impairment loss are recognized for the amount by which the asset's book value exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less costs to sell and the present value of the future cash flows expected to be derived from the asset. Provision for asset impairment is determined and recognized on the individual asset basis. If it is not possible to estimate the recoverable amount of an individual asset, the recoverable amount of a group of assets to which the asset belongs to is determined. A group of assets is the smallest group of assets that is able to generate cash inflows independently. For the goodwill arising from business combination, intangible assets with uncertain service life, and intangible assets which are not ready for intended use, impairment test shall be conducted at least at the end of each year, regardless of whether there are signs of impairment or not. When the Company carry out impairment test to goodwill, the Company shall, as of the purchasing day, allocate on a reasonable basis the book value of the goodwill formed by merger of enterprises to the relevant asset groups, or if there is a difficulty in allocation, to allocate it to the sets of asset groups. Relevant asset groups or the sets of asset groups mean those can benefit from the synergy of business combination. For the purpose of impairment test on the relevant asset groups or the sets of asset groups containing goodwill, if any evidence shows that the impairment of asset groups or sets of asset groups related to goodwill is possible, an impairment test will be made first on the asset groups or sets of asset groups not containing goodwill, thus calculating the recoverable amount and comparing it with the relevant book value so as to recognize the corresponding impairment loss. An impairment test will be made on the asset groups or sets of asset groups containing goodwill to compare the book value of these asset groups or sets of asset groups with the recoverable amount. Where the recoverable amount is lower than the book value, the amount of impairment loss shall set off and be apportioned to the book value of the goodwill in the asset groups or sets of asset groups, and then set off the book value of other assets pro rata according to the proportion of the book value of other assets other than the goodwill in the asset groups or sets of asset groups. Once the above asset impairment loss is recognized, it will not be reversed in the subsequent accounting periods. 26. Long-term deferred expenses Long-term deferred expenses are expenses which have occurred but will benefit over 1 year and shall be amortized over the current period and subsequent periods, and mainly consist of improvement expenditure of fixed assets leased. Long-term deferred expenses are amortized evenly by installments over the estimated benefit period. 27. Contract liabilities The Company lists contract assets or contract liabilities in the balance sheet according to the relationship between performance obligations and customer payments. The Company lists the obligation to transfer commodities or offer services to customers for the consideration received or receivable from customers as contract liabilities. The contract assets and contract liabilities under the same contract are presented in net amount. 245 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. 28. Employee compensation (1) Accountant arrangement method of short-term remuneration During the accounting period when the staff provides service, the Company will recognize the short-term remuneration actually incurred as liabilities, and the liabilities would be charged into current profits and loss or costs of assets. The Company will pay social insurance and housing funds, and will make provision of trade union funds and staff education costs in accordance with the requirements. During the accounting period when the staff provides service, the Company will determine the relevant amount of employee benefits in accordance with the required provision basis and provision ratios. Employee compensation actually incurred by the Company will be included in the current profit or loss or relevant asset costs when actually incurred, in which non-monetary benefits will be measured at the fair value. (2) Accountant arrangement method of retirement benefit plan ①Defined contribution scheme The Company will pay basic pension insurance and unemployment insurance in accordance with the relevant provisions of the local government for the staff. During the accounting period when the staff provides service, the Company will calculate the amount payable in accordance with the local stipulated basis and proportions which will be recognized as liabilities, and the liabilities would be charged into current profits and loss or costs of assets. ②Defined benefit scheme The welfare responsibilities generated from defined benefit scheme based on the formula determined by projected unit credit method would be vested to the service period of the staff and charged into current profits and loss or costs of assets. (3) Accountant arrangement method of termination benefits If the dismissal welfare is provided by the Company to employees, the employee compensation liabilities arising from the dismissal welfare shall be determined at the earliest of the following two, and included in the current profits and losses: When the company cannot unilaterally withdraw the dismissal welfare provided due to the termination of labor relations plan or layoff proposal; When the company determines the costs or expenses associated with the restructuring involving the payment of dismissal welfare. 29. Estimated liabilities The Company shall recognize the obligations related to contingencies as estimated liabilities, when all of the following conditions are satisfied: (1) The obligation is a present obligation of the Company; (2) It is probable that an outflow of economic benefits will be required to settle the obligation; (3) The amount of the obligation can be measured reliably. Estimated liabilities shall be initially measured at the best estimate of the expenditure required to settle the related pres ent obligation. Factors pertaining to a contingency such as risk, uncertainties, and time value of money shall be taken into account as a whole in reaching the best estimate. Where the effect of the time value of money is material, the best estimate shall be determined by discounting the related future cash outflow. 246 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. The expenses required have a successive range, in which the possibilities of occurrence of each result are the same, and the best estimate should be determined as the middle value for the range; in other circumstances, the best estimate will be handled as follows, respectively: For the contingencies involving a single item, it will be determined according to the amount most likely to occur. For the contingencies involving several items, it will be determined according to the possible results and the relevant possibilities. Where some or all of the expenditure required to settle an estimated liability is expected to be reimbursed by a third party, the reimbursement is separately recognized as an asset when it is virtually certain that the reimbursement will be received. The amount recognized for the reimbursement is limited to the book value of the estimated liability. The Company will review the book value of the estimated liabilities on the balance sheet date, and if there are concrete evidences that such book value cannot reflect the current best estimate, the book value will be adjusted according to the current best estimate. 30. Share-based payment The Company's share-based payment refers to a transaction in which an enterprise determines the liabilities on the basis of equity instruments granting or bearing for the acquisition of service from its employees or other parties. The Company's share-based payment is equity-settled. Equity-settled share-based payment and equity instrument: As to an equity-settled share-based payment in return for services of employees, calculation will be based on the fair value of the equity instrument granted to the employees. The share-based payment transactions vested immediately after the date of grant will be included in the relevant cost or expense based on the fair value of the equity instrument on the date of grant, and the capital reserve will be increased accordingly. For the services within the waiting period or the share-based payment transactions that may only be vested when the specified performance conditions are met after the date of grant, the Company will include the services obtained in the current period in relevant cost or expense and increase the capital reserve at the fair value on the date of grant according to the best estimate of the number of the exercisable equity instruments on each balance sheet date in the waiting period. If the terms of the equity-settled share-based payment are amended, the Company shall recognize the services received at least based on the situation before the amendment was made. In addition, any amendment resulting in the increase of the fair value of the equity instrument granted or changes that are beneficial to the staff on the amendment date, will be recognized as an increase in the service received. If the equity instruments vested are canceled during the waiting period, the Company will take the vested equity instruments canceled as accelerated exercise, and immediately include the amount to recognized during the waiting period in the current profit or loss. At the same time, the capital reserve will be recognized. However, if new equity instruments are vested and they are verified at the vesting date of new equity instrument as alternatives vested to canceled equity instruments, the treatment on the new equity instrument is in conformity with the modified treatment on disposal of equity instrument. 31. Income (1) Accounting policies for revenue recognition and measurement If the Company performed the obligations in the contract, revenue shall be recognized when the customer acquires the right of control over relevant commodities or services. Acquisition of control over relevant commodities or services means gaining the ability to direct the use of such commodities or services and obtain nearly all the economic benefits therefrom. If the contract contains two or more performance obligations, the Company shall apportion the transaction price to each 247 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. individual performance obligation on the contract commencement date according to the relative proportion of the individual selling price of the commodities or services promised by each individual performance obligation. The Company measures the revenue according to the transaction price apportioned to each individual performance obligation. The transaction price refers to the amount of consideration that the Company is expected to be entitled to collect due to the transfer of commodities or services to customers, excluding the payments collected on behalf of third parties and the payments expected to be returned to customers. The Company will determine the transaction price according to the contract provisions and its past practices, and may take into account the impact from the variable consideration, the major financing components in the contract, the non-cash consideration, the payable customer consideration and other factors when determining the transaction price. The Company shall determine the transaction price containing the variable consideration according to the amount not exceeding the amount by which the accumulative recognized revenue is much more unlikely to be significantly reversed when relevant uncertainties are eliminated. If there are major financing components in the contract, the Company shall determine the transaction price according to the amount due assumed to be paid in cash when the customer acquires the control over the commodities or services, and shall amortize the difference between such transaction price and the contract consideration using the effective interest rate method during the contract period. When one of the following conditions is met, it belongs to the performance obligation within a certain period of time, or otherwise it belongs to the performance obligation at a certain point of time: The customer acquires and consumes the economic benefits arising from the Company's performance while the company performs the contract. The customer can control the commodities in progress during the Company's performance. The commodities produced by the Company during the performance possess have irreplaceable usage, and the company has the right to collect payment for the performance part accumulated so far during the entire contract period. For the performance obligations performed within a certain period of time, the Company shall recognize the rev enue according to the performance progress within that period of time, except that the performance progress cannot be reasonably determined. The Company will determine the performance progress through the output or input method by taking into account the nature of commodities or services. If the performance progress cannot be reasonably recognized and the costs incurred are expected to be compensated, the Company will recognize the revenue according to the amount of costs incurred until the performance progress can be reasonably recognized. For the performance obligations performed at a certain point of time, the Company will recognize the revenue when the customer acquires the right of control over relevant commodities or services. While determining whether the customer has acquired the control over the commodities or services, the Company shall take the following into consideration: The Company has the current collection right for the such commodities or services, that is, the customer has the current payment obligation for such commodities or services. The Company has transferred the legal title of such commodities to the customer, that is, the customer already has the legal title of such commodities. The Company has transferred the physical commodities to the customer, that is, the customer has possessed the physical commodities. The Company has transferred the major risks and rewards of the commodity title to the customer, that is, the customer has acquired the major risks and rewards of the commodity title. The customer has accepted such commodities or services. (2) Specific principles ①Principle for recognizing revenue from the domestic sales of standard products: The Company's security standard products are sold, through both direct sale and distribution, to the project clients, dealers and other customers. The Company and customers sign sales contracts and send the goods to customers according to the contractual terms of 248 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. delivery, or the customers pick up goods. The revenue is recognized after the customer receives and accepts the goods and the Company obtains the evidence proving the client's receipt of goods. ②Principle for recognizing revenue from the overseas sales of standard products: If the domestic company makes direct export, the FOB and CIF terms are generally adopted and the Company recognizes the sale income after the product is declared and exported. If a foreign subsidiary sells the goods abroad, the goods will be sent to the customer or the customer will collect the goods according to the delivery method agreed with the customer, and the income will be recognized when the customer receives and accepts the goods. ③Principle for recognizing system-integrated sales revenue: The sales of the system-integrated products of the Company include providing the supporting services such as plan design, supporting products, installation, debugging and system trial operation. The sales income will be recognized upon acceptance. ④Principle for recognizing the income from labor services: The income is recognized when the labor service is provided. Difference in the accounting policies for revenue recognition arising from different business models of the same kind of business N/A 32. Government subsidies (1) Type Government grants are monetary assets and non-monetary assets acquired by the Company from the government free of charge. Government grants are classified into government grants related to assets and government grants related to revenue. Government grants related to assets refer to government grants acquired by the Company for the purpose of purchasing or constructing or otherwise forming long-term assets. Government grants related to revenue refer to the government grants other than those related to assets. (2) Confirmation of time point Government grants related to assets will be measured at the actual amount of money received at the time of receipt. The assets (bank deposits) and deferred income shall be period by period included in the profits and losses of the current period in a reasonable and systematic manner from the time the assets are available for use (those related to the Company's daily activities shall be included in other income; those unrelated to the Company's daily activities shall be recognized as non-operating income). When the relevant assets are disposed of (sold, transferred, scrapped, etc.) at or before the end of their service life, the balance of the deferred income that has not yet been apportioned will be transferred to the current-period income from the disposal of the assets on an one-time manner, and will not be deferred. For government grants related to revenue, they will be recognized as profit and loss of the current period according to the amount receivable for government grants obtained under fixed quota standar ds, otherwise, they will be recognized as profit and loss of the current period when it is actually received. (3) Accounting treatment Government grants related to assets shall write off the book value of relevant assets or be recognized as deferred income. When recognized as deferred income, the government grant related to assets will be period by period credited to the profits and losses of the current period in a reasonable and systematic manner within the service life of relevant assets (those related to the Company's daily activities shall be recognized as other income; those unrelated to the Company's daily activities shall be recognized as non-operating income). The revenue-related government grants shall be recognized as deferred income if they are used to compensate relevant expenses or losses in subsequent periods, and they shall be included in profit and loss of the current period (those related to Company's routine activities shall be included in other income; those unrelated to the Company's rout ine activities shall 249 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. be included in non-operating income) or used to offset relevant expenses or losses during the recognition of related expenses or losses; the grants used to compensate related expenses or losses incurred shall be included in profit and loss of the current period (those related to Company's routine activities shall be included in other income; those unrelated to the Company's routine activities shall be included in non-operating income) or used to offset relevant expenses or losses. The policy-oriented concessional loan discount interests obtained by the Company will be subject to accounting treatment in the following two circumstances: ① Where the finance allocates the discount interest funds to the lending bank, and the lending bank provides loans to the Company at the policy preferential interest rate, the Company will take the actually received loan amount as the entry value of the loan, and the relevant borrowing costs shall be calculated according to the loan principal and the policy preferential interest rate. ② If the finance directly allocates the discount interest funds to the Company, the Company will set off the corresponding discount interest against the relevant borrowing costs. 33. Deferred income tax assets / deferred income tax liabilities Income tax comprises current income tax and deferred income tax. Except for the income taxes arising from the business combination and the transactions or matters that are directly included in the owner's equity (including other comprehensive income), the Company will include the current income tax and deferred income tax into the current profit or loss. Deferred income tax assets and deferred income tax liabilities will be calculated and recognized according to the difference (temporary difference) between the tax basis and the book value of assets and liabilities. Deferred income tax assets are recognized to the extent that it is probable that future taxable profits will be available against which deductible temporary differences can be ut ilized. For deductible losses and tax credits that can be reversed in the future period, deferred tax assets shall be recognized to the extent that it is probable that taxable profit will be available in the future to offset the deductible losses and tax credits. Save as the exceptions, deferred income tax liabilities shall be recognized for the taxable temporary difference. The exceptions where deferred income tax assets and liabilities are not recognized include: Initial recognition of the goodwill; Transactions or matters other than business combinations and neither profit nor taxable income (or deductible loss) will be affected when transactions occur. Taxable temporary difference related to investment in the subsidiaries, affiliates and joint ventures will be recognized as deferred income tax liabilities, unless the Company can control the time to reverse such temporary difference and such temporary difference is much more unlikely to be reversed in the predictable future. Deductible temporary difference related to investment in the subsidiaries, affiliates and joint ventures will be recognized as deferred income tax assets when such temporary difference is much more likely to be reversed in the predictable future and is much more likely to be obtained to deduct the taxable income of the deductible temporary difference. On the balance sheet date, the deferred income tax assets and the deferred income tax liabilities will be measured at the tax rate applicable during the recovery of relevant assets or payment of relevant liabilities as expected according to the provisions of the tax law. On the balance sheet date, the Company will review the book value of the deferred income tax assets. If no sufficient taxable income is likely to be obtained to offset the benefits of deferred income tax assets in the future, the book value of deferred income tax assets shall be written down. The amount written down shall be reversed when it is likely to obtain sufficient taxable income. 250 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. After granted the legal rights of net settlement and with the intention to use net settlement or obtain assets and repay debt at the same time, the net amount after offsetting its current income tax assets and current income tax liabilities shall be recorded. On the balance sheet date, the deferred income tax assets and the deferred income tax liabilities will be presented by the net amount after offsetting when the following conditions are fulfilled: The taxpayer is granted the legal rights of net settlement of current income tax assets and current income tax liabilities; Deferred income tax assets and deferred income tax liabilities are related to income tax to be paid by the same entity liable to pay tax to the same tax collection and management authority or related to different e ntities liable to pay tax, but the relevant entity liable to pay tax is intended to apply net settlement of current income tax assets and liabilities or, at the same time, obtain assets, repay debt whenever every deferred income tax assets and liabilities with importance would be reversed in the future. 34. Lease Accounting policy as of January 1, 2021 Lease means the contract by which the lessor transfers the right to use the assets to the lessee for a given period to obtain the consideration. On the commencement of the contract, the Company will assess whether the contract is a lease or contains the lease. If a party to the contract conveys the right to control the use of one or more identified assets for a given period to obtain a consideration, this contract is a lease or contains the lease. If a contract contains several individual leases, the Company will split the contract and conduct accounting treatment of each individual lease separately. If a contact contains both lease and non-lease, the lessee and the lessor will split the lease and non-lease parts. If the rent exemption, delayed payment and other rent reductions arising directly from the COVID-19 outbreak and made with respect to the existing lease contract meet all the following conditions, the Company will simplify all the lease options without assessing whether the lease is changed or reassessing the lease classification: The lease consideration after reduction is less or remains substantially the same compared with the lease considerati on before reduction, and the lease consideration may either be undiscounted or discounted by the discount rate before reduction; The reduction is only applicable to the lease payment payable before June 30, 2022. The increase of the lease payment payable after June 30, 2022 has no impact on satisfaction of this condition and the decrease of the lease payment after June 30, 2022 will cause failure to meet this condition; Other terms and conditions of lease are identified without significant change after taking the qualitative and quantitative factors into full account. (1) The Company as a lessee ① Right-of-use Assets The Company recognizes the right-to-use assets for the lease other than short-term lease and low-value asset lease on the commencement of the lease term. The right-to-use assets are initially measured at cost which includes: Initial measurement amount of lease liabilities; The lease payment paid on or before the commencement of the lease term; if there are lease incentives, the relevant amount of lease incentives enjoyed shall be deducted; Initial direct cost incurred by the Company; The estimated costs incurred by the Company for dismantling and removing the leased asset, restoring the site where the leased asset is located or restoring the leased asset to the state agreed in the lease terms, but excluding the cost incurred to produce the inventory. 251 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. The Company will depreciate the right-to-use assets through the straight-line method. If it can be reasonably recognized that the title of the leased asset is acquired at the expiration of the lease term, the Company shall accrue depreciation within the remaining service life of the leased asset; or otherwise, the leased asset shall be depreciated within the shorter of the lease term and the remaining service life of the leased asset. The Company will determine whether the right-of-use assets are impaired and conduct accounting treatment over the identified impairment loss according to the principles set out in this section Financial Report - (V) Significant Accounting Polices and Accounting Estimates - 25. Impairment of long-term assets. ② Lease Liabilities The Company recognizes the lease liabilities for the lease other than short-term lease and low-value asset lease on the commencement of the lease term. Lease liabilities shall be initially measured at the present value of the unpaid lease payments. Lease payments include: Fixed payment (including actual fixed payment), and if there are lease incentives, the relevant amount of lease incentives shall be deducted; Variable lease payment depending on the index or ratio; Predicted payment on the basis of the guaranteed residual value provided by the Company; Exercise price of the call option, provided that the Company will exercise such option, as reasonably determined; Payment for exercise of the lease termination option, provided that the lease term reflects the Company’s future exercise of the lease termination option. The interest rate implicit in lease is applied by the Company as the discount rate. If the interest rate implicit in lease cannot be reasonably determined, the Company's interest rate on incremental borrowings is applied as the discount rate. The Company shall calculate the interest expense of the lease liabilities during each period of the lease term at a fixed periodic interest rate and include it in the current profit or loss or relevant asset cost. The variable lease payment which is not included in the measurement of lease liabilities shall be included in the current profit or loss or relevant asset cost when actually incurred. If any of the following circumstances happens on commencement of the lease term, the Company will remeasure the lease liabilities and adjust the corresponding right-of-use assets, and if the book value of the right-of-use assets has been reduced to zero, but the lease liabilities still need to be further reduced, the difference shall be included in the current profit or loss: When the assessment result of the call option, renewal option or termination option is changed or the actual exercise of the aforesaid option is inconsistent with the original assessment result, and the Company remeasures the lease liabilities at the present value worked out according to the changed lease payment an d the revised discount rate; When there are changes in the actual fixed payment, the estimated payable amount of guaranteed residual value, or the index or ratio applied to determine the amount of lease payments, the Company remeasures the lease liabilit ies at the present value worked out according to the changed lease payment and the original discount rate. If the change in the lease payment originates from the change in the floating interest rate, the present value will be calculated using the revised discount rate. ③ Short-term lease and low-value asset lease The Company chooses not to recognize the right-of-use assets and lease liabilities for the short-term lease and low-value asset lease, and records relevant lease payment into the current profit or loss or relevant asset cost according to the straight-line method in each period of the lease term. Short-term lease means the lease of no more than 12 months and excluding the call option on the commencement of the lease term. Low-value asset lease means a lease of lower value when the single leased asset is brand-new. If the Company sublets or is expected to sublet the leased assets, the original 252 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. lease is not a low-value asset lease. ④ Lease change If the lease is changed and meets all of the following conditions, the Company will conduct accounting treatment with respect to such lease change as a single lease: Such lease change has expanded the scope of lease by adding the right to use one or more leased assets; The increased consideration and the separate consideration for the expanded part of the scope of lease shall be equivalent to the amount adjusted according to this contract. If the lease change is not subject to accounting treatment as a single lease, on the effective date of the lease change, the Company will re-apportion the consideration of the changed contract, re-determine the lease term and remeasure the lease liabilities at the present value worked out according to the changed lease payment and the revised discount rate. If the lease change results in narrower scope of lease or shorter lease term, the Company will reduce the book value of the right-of-use assets accordingly, and will include relevant gain or loss from partial or full termination of the lease in the current profit or loss. If other lease changes result in re-measurement of the lease liabilities, the Company will adjust the book value of the right-to-use assets accordingly. ⑤ Rent reduction related to the COVID-19 outbreak If the rent reduction simplification method is adopted because of the COVID-19 outbreak, the Company will not assess whether a lease change has been incurred, but will continue to calculate the interest expense of the lease liabilities by the discount rate that is consistent with the one used before the reduction and include it in the current profit or loss, and will continue to accrue depreciation over the right-of-use assets through the method that is consistent with the one used before the reduction. In case of rent reduction, the Company will take the reduced rent as the variable lease payment, and when a reduction agreement or any other agreement is reached to relieve the obligation to pay the original rent, the undiscounted amount or the amount discounted according to the discount rate used before the reduction will be used to set off relevant asset cost or expense, and meanwhile, the lease liabilities will be adjusted accordingly; if the payment of the rent is delayed, the Company will set off the previously recognized lease liabilities when they are actually paid. For the short-term lease and low-value asset lease, the Company will continue to include the rent in the original contract into relevant asset cost or expense through the method that is consistent with the one used before the reduction. In c ase of rent reduction, the Company will take the reduced rent as the variable lease payment to set off relevant asset cost or expense during the reduction; if the payment of rent is delayed, the Company will recognize the rent payable in the original payment period as the account payable to set off the previously recognized account payable when it is actually paid. (2) The Company as a lessor On commencement of the lease term, the Company will divide the lease into financial lease and operating lease. Financial lease means the lease that has substantially transferred almost all the risks and rewards related to the title of the leased assets, whether or not the title will be finally transferred. Operating lease means any lease other than financial lease. When the Company serves as a lessor of the sublease, the sublease will be classified on the basis of the right -to-use assets resulting from the original lease. ① Accounting treatment of operating lease The lease receipts for the operating lease will be recog nized as the rental income according to the straight-line method during each period of the lease term. The initial direct fee related to the operating lease to be incurred by the Company will be capitalized and will be apportioned and included in the current profit or loss on the same basis as that for recognition of the rental income in the lease term. The variable lease payments that are not included in the lease receipts shall be 253 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. included in the current profit or loss when they actually occur. In case of a change to the operating lease, the Company will conduct accounting treatment with respect to the changed operating lease as a new lease as of the effective date of the change, and the lease payments received in advance or receivable with respect to the lease before the change will be taken as the lease receipts for the new lease. ② Accounting treatment of financial lease On the commencement of the lease term, the Company will recognize the financial lease receivables for the financial lease, and derecognize the financial lease assets. The Company will take the net lease investment as the entry value of the financial lease receivables when initially measuring the financial lease receivables. The net lease investment is the sum of the unguaranteed residual value and the present value of the unreceived lease receipts discounted according to the interest rate implicit in the lease on the commencement of the lease term. The Company will calculate and recognize the interest income during each period of the leas e term at a fixed periodic interest rate. The derecognition and impairment of the financial lease receivables will be subject to accounting treatment according to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 10. Financial instruments. The variable lease payments that are not included in the measurement of the net lease investment shall be included in the current profit or loss when they actually occur. If the financial lease is changed and meets all of the following conditions, the Company will conduct accounting treatment with respect to such change as a single lease: Such change has expanded the scope of lease by increasing the right to use one or more leased assets; The increased consideration and the separate consideration for the expanded part of the scope of lease shall be equivalent to the amount adjusted according to this contract. If the change in the financial lease is not subject to accounting treatment as a single lease, the Company will treat the changed lease in the following circumstances: If the change takes effect on commencement of the lease term and the lease is classified as operating lease, the Company will conduct accounting treatment with respect to such lease as a new lease as of the effective date of the lease change, and will take the net lease investment before the effective date of the lease change as the book value of the leased asset; If the change takes effect on the commencement of the lease term, and such lease is classified as the financial lease, the Company will conduct accounting treatment according to the policy regarding modification or re-negotiation of the contract in this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 10. Financial instruments. ③ Rent reduction related to the COVID-19 outbreak For the operating lease which is subject to the rent reduction simplification method because of the COVID -19 outbreak, the Company will continue to recognize the original contract rent as the lease income through the method that is consistent with the one used before the reduction; in case of rent reduction, the Company will take the reduced rent as the variable lease payment to set off the lease income during the reduction; if the payment of rent is delayed, the Company will recognize the rent receivable in the original collection period as the account receivable to set off the previously recognized account receivable when it is actually received. For the financial lease subject to the rent reduction simplification method because of the COVID-19 outbreak, the Company will continue to calculate the interest expense by the discount rate that is consistent with the one used before the reduction and recognize it as the lease income. In case of rent reduction, the Company will take the reduced rent as the variable lease payment, and when a reduction agreement or any other agreement is reached to waive the right to 254 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. collect the original rent, the undiscounted amount or the amount discounted according to the discount rate used before the reduction will be used to set off the previously recognized lease income, and the uncovered part will be included in the investment income, and meanwhile, the financial lease receivables will be adjusted acc ordingly; if the collection of the rent is delayed, the Company will set off the previously recognized financial lease receivables when they are actually received. (3) Sale and leaseback transaction The Company evaluates and determines whether the asset transfer in the sale and leaseback transaction belongs to a sale in accordance with the provisions of this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 31. Income. ① The Company as a lessee If the asset transfer in the sale and leaseback transaction is a sale, the Company as the lessee shall measure the right-of-use asset arising from the sale and leaseback according to the part related to the right of use acquired from the leaseback in the original book value of the asset, and only recognize relevant gain or loss on the rights transferred to the lessor; if the asset transfer in the sale and leaseback transaction is not a sale, the Company as the lessee shall continue to recognize the transferred asset, and recognize a financial liability equal to the transfer income. For accounting treatment of the financial liabilities, refer to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 10. Financial instruments. ② The Company as a lessor If the asset transfer in the sale and leaseback transaction is a sale, the Company as the lessee shall conduct accounting treatment with respect to the asset purchase and conduct accounting treatment with respect to the asset lease according to the policy in the foregoing "2. The Company as a lessor"; if the asset transfer in the sale and leaseback transaction is not a sale, the Company as the lessor shall derecognize the transferred asset, but recognize a financial asset equal to the transfer income. For accounting treatment of the financial assets, refer to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 10. Financial instruments. Accounting policy before January 1, 2021 The lease is divided into financial lease and operating lease. Financial lease means the lease that has substantially transferred all the risks and rewards related to the title of the assets. Operating lease means any lease other than financial lease. If the rent exemption, delayed payment and other rent reductions arising directly from the COVID-19 outbreak and made with respect to the existing lease contract meet all the following conditions, the Company will simplify all the lease options without assessing whether the lease is changed or reassessing the lease classification: The lease consideration after reduction is less or remains substantially the same compared with the lease consideration before reduction, and the lease consideration may either be undiscounted or discounted by the discount rate before reduction; The reduction is only applicable to the lease payment payable before Wednesday, June 30, 2021. The increase of the lease payment payable after Wednesday, June 30, 2021 has no impact on satisfaction of this condition and th e decrease of the lease payment after Wednesday, June 30, 2021 will cause failure to meet this condition; Other terms and conditions of lease are identified without significant change after taking the qualitative and quantitative factors into full account. (1) Accounting treatment of operating lease ①As the lessee of operating leases, rental payments under operating leases are recognized as costs or expenses on a straight line basis over the lease term (including rent free periods). Initial direct costs that are attributable to an operating 255 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. lease incurred by the Company are charged to current profit and loss. When the lesser bears the lease related expenses which should be undertaken by the Company, the Company shall deduct this part of expense from the rent and amortize the net amount over the lease term. For the operating lease which is subject to the rent reduction simplification method because of the COVID -19 outbreak, the Company will continue to include the rent in the original contract into relevant asset cost or expense through the method that is consistent with the one used before the reduction. In case of rent reduction, the Company will take the reduced rent as the contingent rent and include it in the profit or loss during the reduction; if the payment of rent is delayed, the Company will recognize the rent payable in the original payment period as the account payable to set off the previously recognized account payable when it is actually paid. ②Leasing charges received by the Company for the assets leased out shall be amortized in a straight-line basis over the lease term without deducting the rent-free periods, and recognized as leasing income. The initial direct fee related to the leasing transactions paid by the Company shall be charged to current expenses; if the mount is significant, it shall be capitalized and charged to current income evenly on the same basis as the leasing income is recognized over the lease term. When the Company bears the lease related expenses which should be undertaken by the lessee, the Company shall deduct this part of expense from the rent income, and amortize the net amount over the lease term. For the operating lease which is subject to the rent reduction simplification method because of the COVID -19 outbreak, the Company will continue to recognize the original contract rent as the lease income through the method that is consistent with the one used before the reduction; in case of rent reduction, the Company will take the reduced rent as the contingent rent to set off the lease income during the reduction; if the payment of rent is delayed, the Company will recognize the rent receivable in the original collection period as the account receivable to set off the previously recognized account receivable when it is actually received. (2) Accounting treatment of financial lease ①Assets acquired under finance leases: At the initiation date of the lessee, the leased asset is recorded at the amounts equal to the lower of the fair value of the leased asset and the present value of the minimum lease payments. The balance is accounted for as unrecognized finance charge and is amortized using the effective interest method over the period of the lease. The Company, by means of the real interest method, amortizes the unacknowl edged financial charges during the lease term of the assets and includes them into financing expenses. Initial direct cost incurred by the Company will be included in the assets acquired under finance leases. For the financial lease subject to the rent reduction simplification method because of the COVID-19 outbreak, the Company will continue to recognize the unrecognized financial charges as the current financial charges according to the discount rate that is consistent with the one used before the reduction and will continue to accrue depreciation over the assets acquired under finance leases through the method that is consistent with the one used before the reduction.

Changes in significant accounting policies and accounting estimates (1) Changes in significant accounting policies ① Implementation: Accounting Standards for Business Enterprises No.21 - Leases (2018 Edition) The Ministry of Finance amended the Accounting Standards for Enterprises No.21 – Leases (hereinafter referred to as "New Lease Criteria") in 2018. The Company has implemented the new lease criteria since January 1, 2021. According to the amended criteria, the Company chooses not to re-assess whether the contract existing before the first execution date is a lease or contains a lease on the first execution date. The Company as a lessee 257 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. The Company chooses to adjust the retained earnings at the beginning of the current year in which the new lease criteria are first executed and the amount of other related item in the financial statements according to the cumulative impact of the new lease criteria implemented on the first execution date, and the information in the comparable periods is not adjusted. For the operating lease existing before the first execution date, the Company will measure the lease liabilities at the present value discounted from the interest rate on incremental borrowings of the Company on the first execution date according to the remaining lease payments, and will measure the right-of-use assets by one of the two approaches according to each lease option: - It is assumed that the book value of the new lease criteria will be adopted from the commencement of the lease term, and the interest rate on incremental borrowings of the Company on the first execution date will be taken as the discount rate. - The amount equal to the lease liabilities will be adjusted, as necessary, according to the prepaid rent. For the operating lease before the first execution date, the Company will adopt one or more of the following simplified treatments per each lease while applying the above methods: 1) The lease completed within 12 months from the first execution date will be treated as the short-term lease; 2) The same discount rate will apply to the lease with similar characteristics when measuring the lease liabilities; 3) The right-of-use assets will be measured exclusive of initial direct cost; 4) If there is a renewal option or lease termination option, the lease term will be determined according to the actual exercise of the option before the first execution date and other latest information; 5) In lieu of the impairment test of the right-of-use assets, the contract containing the lease will be assessed according to this section Financial Report - V. Significant Accounting Polices and Accounting Estimates - 29. Estimated liabilities to determine whether it is a loss-making contract before the first execution date, and the right-of-use assets will be adjusted according to the amount of reserve for loss included in the balance sheet before the first execution date; 6) The lease change occurring before the first execution date will not be subject to retroactive adjustment, but will be subject to accounting treatment on the basis of the new lease criteria according to the final arrangement of lease change. When measuring the lease liabilities, the Company will discount the lease payments by using the interest rate on incremental borrowings (weighted average value: 4.75%) of the lessee on January 1, 2021. Minimum unpaid lease payment for the major operating lease disclosed in the consolidated financial 156,110,270.79 statements as at December 31, 2020 Present value discounted according to the interest rate on incremental borrowings of the Company 145,067,810.69 on January 1, 2021 Lease liabilities under the new lease criteria on January 1, 2021 (including lease liabilities due within 145,067,810.69 one year) Difference between the above discounted present value and the lease liabilities For the financial lease existing before the first execution date, the Company will separately measure the right-of-use assets and the lease liabilities at the original book value of the assets acquired under finance leases and the lease payments payable on the first execution date. The Company as a lessor The sublease that is classified as an operating lease before the first execution date and is still existing after the first execution date will be reassessed by the Company on the first execution date on the basis of the remaining contract term and terms of the original lease and the sublease, and be reclassified according to the new lease criteria. If it is reclassified as a financial lease, the Company will take it as a new financial lease for accounting treatment. 258 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. Except for the sublease, the Company is not required to adjust the lease in which it is a lessor according to the new lease criteria. The Company will conduct accounting treatment according to the new lease criteria from the first execution date on. The new lease criteria adopted by the Company have the following main effects on the financial statements: Unit: RMB Content and Reasons for Affected Statement Items Impact Amount of Balance on January 1, 2021 Change in Accounting Policies Consolidated Subsidiaries Parent company (1) Adjustment of the operating Prepayments -9,255,773.15 -7,480,693.68 lease existing before the first Other Receivables -1,452,172.37 -141,861.28 execution date by the Company Other Current Assets 102,047.54 as a lessee Right-of-use Assets 155,673,708.67 82,586,983.09 Non-current Liabilities Due within 1 Year 58,971,448.27 29,457,938.99 Lease Liabilities 86,096,362.42 45,506,489.14 ② Implementation of Interpretation of Accounting Standards for Business Enterprises No.14 On February 2, 2021, the Ministry of Finance released the Interpretation of Accounting Standards for Business Enterprises No.14 (CaiKuai (2021) No. 1, hereinafter referred to as “Interpretation No. 14”), which was implemented as of the date of release.

Risks Relating to Financial Instruments In the business operation, the Company is facing with various financial risks: credit risk, liquidity risk and market risk (including exchange rate risk, interest rate risk and other price risks). The overall objective of the Company's risk management is to formulate risk management policies that can minimize risks 339 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd. without affecting the Company's competitiveness and adaptability to changes too much. (I) Credit Risk The credit risk refers to the risk of financial loss to the Company as a result of a counterparty's failure to fulfill its contractual obligations. The Company is mainly facing with the customer credit risk arising from sales on account. Before signing a new contract, the Company will assess the new customer's credit risk, including external credit rating and the credibility letter from a bank under some circumstances (if such information is available). The Company has set a credit limit for sales on account for each customer. Such limit shall be the maximum amount with no additional approval needed. The Company ensures that the overall credit risk is within the controllable range through quarterly monitoring of credit ratings of existing customers, and monthly review of aging analysis on accounts receivable. When monitoring customers' credit risk, the Company groups them according to their credit characteristics. Customers rated as "high risk" will be placed on the restricted customer list. The Company can provide them with O/A in the future period only when additional approval is obtained. Otherwise they must make relevant payment in advance. For overseas customers, the Company mainly uses wire tra nsfer as a payment method. According to the credit evaluation of each customer, the Company gives different credit lines and credit account periods, and agrees on the payment method and account period in the commodity procurement contract between the two p arties. After the sales of products, the Company has a dedicated person responsible for tracking, reconciliation, and payment reminding. In addition, the Company introduced export credit insurance to ensure that the return risk from overseas customers is w ithin controllable range. (II) Liquidity Risk Liquidity risk refers to the risk of a shortage of funds when an enterprise fulfills its obligation of settlement by cash or other financial assets. The Company's policy is to ensure that there is sufficient cash to repay the liabilities due. The liquidity risk is under the concentrated control of the Company's Financial Department. Through monitoring the balance of cash and securities cashable at any time and rolling forecasting the cash flow in the next 12 months, the Financial Department ensures that the Company has sufficient funds to repay its debts under all reasonable predictions. The financial liabilities of the Company are listed as follows based on the undiscounted contractual cash flow: Item December 31, 2021 Within 1 year 1 years or above Total Short-term loan 325,648,230.98 325,648,230.98 Notes Payable 4,472,998,965.03 4,472,998,965.03 Accounts Payable 7,329,740,650.71 7,329,740,650.71 Other Payables 677,752,701.47 677,752,701.47 Non-current Liabilities Due 897,508,057.06 897,508,057.06 within 1 Year Long-term loan 1,552,500,000.00 1,552,500,000.00 Lease Liabilities 154,577,298.75 154,577,298.75 Total 13,703,648,605.25 1,707,077,298.75 15,410,725,904.00 Item December 31, 2020 Within 1 year 1 years or above Total 340 2021 Annual Report of Zhejiang Dahua Technology Co., Ltd.

Interest rate risk The interest rate risk refers to the risk in which the fair value or future cash flow of financial instruments changes due to the change of market interest rate. The interest rate risk faced with by the Company is mainly from bank loans. The Company's assets and liabilities relating to interest rate are respectively bank deposits and short-term loans, whose interest rate risk is low. 2. Exchange rate risk The exchange rate risk refers to the risk in which the fair value or future cash flow of financial instruments changes due to the change of foreign exchange rate. The Company will try its best to match the revenues with the expenses in foreign currency, to lower the exchange rate risk.
