The Company classifies and collects long-term accounts receivables, while increasing assessment efforts, implementing reward and punishment measures, urging timely recovery of payments, strengthening inventory management, and enhancing inventory liquidity.

Serial of Auditing Report DAXIN SHEN ZI [2023]No. 1-01215 Name of CPA Wang Fangquan Guo Zhigang Auditor’s Report DAXIN SHEN ZI [2023]No. 1-01215 To the Shareholders of Nanjing Putian Telecommunications Co., Ltd.: I. Opinion We have audited the financial statements of Nanjing Putian Telecommunications Co., Ltd (hereafter referred to as “the Company”), which comprise the consolidated and the Company's balance sheets as at December 31, 2022, the consolidated and the Company's statements of income, the consolidated and the Company's statements of cash flows and the consolidated and the Company's statements of changes in equity for the year then ended, and notes to the financial statements. In our opinion, the accompanying financial statements give a true and fair view of the financial position of the Company as at December 31, 2022, and of its financial performance and cash flows for the year then ended in accordance with Accounting Standards for Business Enterprises. II. Basis for Opinion We conducted our audit in accordance with Chinese Certified Public Accountants Auditing Standards. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Statements section of our report. We are independent of the Company in accordance with the Code of Ethics for Chinese Certified Public Accountants and have fulfilled our other ethical responsibilities in accordance with the Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion. III. Key Audit Matters Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial statements of the current period. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. (I) Revenue recognition 1. Event description As stated in notes III (24) of the financial statements and notes V(34), Operating revenue and operating costs, the sales revenue of the company in 2022 was 879,56.60 ten thousand yuan. Operating income is one of the company's key performance indicators and an important part of the source of profit. There is an inherent risk that management manipulates revenue recognition for specific purposes, and we therefore identify revenue recognition as a critical audit event. 2. Audit response (1) Understand and evaluate the revenue process of transaction booking and key internal controls of management. (2) Select samples of revenue transactions recorded in the reporting period, check sales orders, sales invoices, shipping records, customer receipt documents and other materials, and evaluate whether relevant revenue recognition conforms to your company's accounting policies for revenue recognition. (3) Perform analytical review procedures for operating revenue and gross profit margin based on product, customer and other dimensions to judge the rationality of changes in operating revenue and gross profit margin. (4) Confirm the sales revenue generated by major customers and the balance of accounts receivable to evaluate the authenticity and accuracy of your company's revenue recognition. (5) Perform sample tests on sales revenue recognized around the balance sheet date to assess whether sales revenue is recognized in the appropriate period. (II) Provision for bad debts of accounts receivable Event description The relevant disclosures are detailed in notes III (11) and V (4) to the financial statements. As of December 31, 2022, the book balance of accounts receivable of the company is 49,850.52 ten thousand yuan, the balance of bad debt reserve is 19,388.90 ten thousand yuan, and the book value is 30,461.62 ten thousand yuan, accounting for 34.17% of the total assets The management of your company (hereinafter referred to as the management) measures its loss reserve in accordance with the expected credit loss amount equivalent to the entire duration based on a single account receivable or a combination of accounts receivable based on the credit risk characteristics of each account receivable. For the receivables that measure expected credit losses 99 Full text of the Annual Report 2022 of Nanjing Putian Telecommunications Co., Ltd. on a single item basis, the management estimates the expected cash flow by taking into account reasonable and evidence -based information about past events, current conditions and future economic conditions, and determines the allowance for bad debts accordingly. For accounts receivable that measure expected credit loss on the basis of portfolio, the management divides the portfolio based on aging, refers to historical credit loss experience and makes adjustments according to forward-looking estimates, and prepares a comparison table between aging accounts receivable and expected credit loss rate to determine the allowance for bad debts. Due to the significant amount of accounts receivable and the significant management judgment involved in the impairment test of accounts receivable, we identified the impairment of accounts receivable as a critical audit matter. 2. Audit response For the impairment of accounts receivable, our audit procedures mainly include: (1) Understand and evaluate the design and operational effectiveness of key internal controls related to accounts receivable bad debt reserve;; (2) For the accounts receivable for which bad debt provision is made according to individual assessment, we have sampled and reviewed the basis for the management to calculate the recoverable amount, including the management's assessment of the customer's credit risk based on the customer's current credit status, repayment willingness and repayment ability; (3) For the accounts receivable set aside for bad debts according to the aging combination, we sampled the key information such as aging and overdue days; (4) We reviewed management's calculation of allowance for doubtful accounts receivable; (5) Implement confirmation of large and important accounts receivable, and evaluate the rationality of the management's provision for bad debts of accounts receivable based on procedures such as post-period collection and long-term reason analysis of accounts receivable. IV. Other Information The directors of the Company are responsible for the other information. The other information comprises all of the information included in the annual report other than the financial statements and our auditor’s report thereon. Our opinion on the financial statements does not cover the other information and we do not express any form of assurance conclusion thereon. In connection 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 the Directors and Those Charged with Governance for the Financial Statements The directors of the Company are responsible for the preparation of financial statements that give a true and fair view in accordance with Accounting Standards for Business Enterprises, and for such internal control as the directors determine is necessary to enable the preparation of the financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the directors are responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the Company or to cease operations or have no realistic alternative but to do so. Those charged with governance are responsible for overseeing the Company’s financial reporting process. VI. Certified Public Accountant’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 auditor’s 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 auditing 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 taken on the basis of these financial statements. As part of an audit in accordance with auditing standards, we exercise professional judgement and maintain professional scepticism throughout the audit. We also: A. 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 for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. B. Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. C. Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors. D. Conclude on the appropriateness of the directors’ use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our a uditor’s report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusion s are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern. E. Evaluate the overall presentation, structure and content of the financial statements, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation. 100 Full text of the Annual Report 2022 of Nanjing Putian Telecommunications Co., Ltd. F. Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Company to express an opinion on the financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion. We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit a nd significant audit findings, including any significant deficiencies in internal control that we identify during our audit. We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards. 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 auditor’s 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 would reasonably be expec ted to outweigh the public interest benefits of such communication.

The Company classifies the financial assets that meet the following conditions as those measured at fair value and whose changes are included in other comprehensive income: ① The Company's business model of managing financial assets aims at both collecting contract cash flow and selling the financial assets; ② The terms of the contract of the financial asset stipulate that the cash flow generated on a specified date is only the payment of the principal amount and the interest based on the outstanding principal amount. For investments in non-trading equity instruments, the Company may, upon initial recognition, irrevocably designate them as financial assets measured at fair value and whose changes are included in other comprehensive income. The designation is made on an individual investment basis and the 116 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 underlying investment meets the definition of an equity instrument from the issuer's point of view. In addition to financial assets classified as financial assets measured at amortized cost and financial assets measured at fair value and whose changes are booked into other comprehensive income, the Company classifies them as financial assets measured at fair value and whose changes are booked into current profit and loss. In the initial recognition, if accounting mismatch can be eliminated or reduced, the Company may irrevocably designate financial assets as financial assets measured at fair value and whose changes are recorded into current profit and loss. When the Company changes the business model of managing financial assets, it will reclassify all the affected financial assets on the first day of the first reporting period after the change of the business model, and adopt the future applicable method to conduct relevant accounting treatment from the reclassification date, without retroactive adjustment of previously recognized gains, losses (including impairment losses or gains) or interest. (2) Financial liabilities Financial liabilities at the initial recognition are classified as: financial liabilities measured at fair value and whose changes are booked into current profit and loss; The financial assets transfer does not meet the conditions for termination of recognition or continues to involve the financial liabilities formed by the transferred financial assets; Financial liabilities measured at amortized cost. All financial liabilities are not reclassified. 2. Measurement of financial instruments The Company's financial instruments are initially recognized as measured at fair value. For financial assets and financial liabilities measured at fair value and whose changes are booked into current profit and loss, relevant transaction costs are directly booked into current profit and loss; For other types of financial assets or financial liabilities, related transaction costs are included in the initial recognized amount. For accounts receivable or notes receivable arising from the sale of products or the provision of services that do not contain or take into account significant financing components, the amount of consideration to which the Company is entitled to collect as expected shall be the initial recognition amount. Subsequent measurement of financial instruments depends on their classification. (1) Financial assets ①Financial assets measured at amortized cost. After the initial recognition, such financial assets are measured by the amortized cost using the effective interest rate method. The gains or losses generated by financial assets measured at amortized cost and not belonging to any hedging relationship shall be booked into current profit and loss when recognition is terminated, reclassified, amortized according to the effective interest rate method or impairment is recognized. ②Financial assets that are measured at fair value and whose changes are booked into current profit or loss. After the initial recognition, such financial assets (except part of the financial assets belonging to the hedge relationship) shall be measured at the fair value, and the resulting gains or losses (including interest and dividend income) shall be booked into current profit and loss. ③Investment in debt instruments that are measured at fair value and whose changes are recorded in other comprehensive income. After the initial recognition, the fair value of such financial assets is used for subsequent measurement. Interest, impairment losses or gains and exchange gains and losses calculated using the effective interest rate method are included in current profit and loss, while other gains or losses are included in other comprehensive income. Upon termination of recognition, the accumulated gains or losses previously booked into other comprehensive income shall be transferred out of other comprehensive income and booked into current profit and loss. (2) Financial liabilities ① Financial liabilities measured at fair value and whose changes are booked into current profit and loss. Such financial liabilities include trading financial liabilities (including derivative instruments belonging to financial liabilities) and financial liabilities designated as measured at fair value and whose changes are booked into current profit and loss. After the initial recognition, the fair value of such financial liabilities is used for subsequent measurement. Except for the hedge accounting, the gain or loss (including interest expense) generated by the change in the fair value of trading financial liabilities is booked into current profit and loss. If a financial liability is specified as a financial liability measured at fair value and its change is included in current profit and loss, the 117 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 change in the fair value of the financial liability caused by the change of the enterprise's own credit risk shall be included in other comprehensive income, and the change in other fair value shall be included in current profit and loss. If accounting mismatch in profit and loss will be caused or expanded if the impact of the change in credit risk of the financial liability is included in other comprehensive income, the Company shall book all gains or losses of the financial liability into current profit and loss. ② Financial liabilities measured at amortized cost. After the initial recognition, such financial liabilities are measured at amortized cost using the effective interest rate method. 3. The Company's method of recognizing the fair value of financial instruments If there are financial instruments in active markets, their fair value shall be determined by quotation in active markets; If there is no active market for financial instruments, use valuation techniques to determine their fair value. Valuation techniques mainly include market method, income method and cost method. In limited cases, if recent information used to determine fair value is insufficient, or if the distribution of possible estimates of fair value is wide, and cost represents the best estimate of fair value within the range, the cost may represent its appropriate estimate of fair value within the range of distribution. The Company uses all information about the investee's performance and operations available after the initial confirmation date to determine whether the cost represents fair value. 4. Recognition basis and measurement method for transfer of financial assets and financial liabilities (1) Financial assets The financial assets of the Company shall be terminated if they meet one of the following conditions: (1) The contractual right to collect the cash flow of the financial assets shall be terminated; (2) The financial assets have been transferred, and the company has transferred almost all the risks and rewards of the ownership of the financial assets; (3) The financial assets have been transferred. Although the Company has neither transferred nor retained almost all rewards on the ownership of the financial assets, it has not retained control of the financial assets. Where the Company neither transfers nor retains almost all remuneration on the ownership of the financial assets, and retains control over the financial assets, the relevant financial assets shall be recognized according to the degree of continued involvement in the transferred financial assets, and the relevant liabilities shall be recognized accordingly. If the transfer of financial assets meets the conditions for termination of recognition as a whole, the difference between the following two amounts shall be recorded into the current profit and loss: (1) the book value of the transferred financial assets on the date of termination of recognition; (2) The sum of the consideration received due to the transfer of financial assets and the amount corresponding to the part of termination of recognition in the accumulative amount of the change in fair value directly included in other comprehensive income (the financial assets involved in the transfer are financial assets classified as measured at fair value and whose change is included in other comprehensive income). If the partial transfer of financial assets meets the conditions for termination of recognition, the book value of the whole transferred financial assets shall be apportioned between the terminated and unterminated part according to their relative fair value on the transfer date, and then the difference of the following two amounts shall be recorded into current profit and loss: (1) The book value of the terminated recognition part on the termination of recognition date; (2) The sum of the consideration received for the part of termination recognition and the amount corresponding to the part of termination recognition in the accumulative amount of changes in fair value originally included in other comprehensive income (financial assets involved in transfer are financial assets classified as measured at fair value and whose changes are included in other comprehensive income). (2) Financial liabilities If the current obligation of the financial liability (or part thereof) has been discharged, the Company shall terminate the recognition of the financial liability. If the recognition of financial liabilities (or part thereof) is terminated, the Company shall book the difference between the book value and the consideration paid into the current profit and loss. (XI) Methods for determining expected credit losses and accounting treatment 1. Methods for determining expected credit losses 118 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 Based on expected credit losses, the Company conducts impairment accounting treatment and recognizes loss reserves for financial assets (including receivables) measured at amortized cost, financial assets classified as measured at fair value and whose changes are included in other comprehensive income (including receivables financing), lease receivables. On each balance sheet date, the company evaluates whether the credit risk of relevant financial instruments has significantly increased since the initial recognition. The process of credit impairment of financial instruments is divided into three stages, and different accounting treatment methods are adopted for the impairment of financial instruments at different stages: (1) In the first stage, if the credit risk of the financial instrument does not increase significantly after the initial recognition, the Company shall calculate the loss reserve based on the expected credit loss of the financial instrument in the next 12 months, and calculate the interest income based on its book balance (i.e. without deducting the impairment reserve) and the actual interest rate; (2) In the second stage, if the credit risk of the financial instrument has increased significantly since the initial recognition but no credit impairment has occurred, the Company shall measure the loss reserve according to the expected credit loss during the entire duration of the financial instrument and calculate the interest income according to its book balance and actual interest rate; (3) In the third stage, if credit impairment occurs after the initial recognition, the Company shall measure the loss reserve according to the expected credit loss during the entire duration of the financial instrument, and calculate the interest income according to its amortized cost (book balance minus impairment reserve already drawn) and the actual interest rate. (1) Lower credit risk financial instruments measure loss reserve method For financial instruments with lower credit risk at the balance sheet date, the Company may directly assume that the credit risk of such instruments has not increased significantly since the initial recognition, without comparing them with the credit risk at the time of their initial recognition. If the default risk of the financial instrument is low, the debtor has a strong ability to perform its contractual cash flow obligations in the short term, and even if there are adverse changes in the economic situation and business environment in a longer period of time, it may not necessarily reduce the borrower's ability to perform its contractual cash flow obligations, the financial instrument is regarded as having a low credit risk. (2) How to measure loss reserve for receivables and lease receivables ① Receivables that do not contain significant financing components. For receivables that are formed from transactions regulated by Accounting Standard for Business Enterprises No. 14 - Revenue and do not have a significant financing component, the Company adopts a simplified approach that always measures the loss reserve against expected credit losses over the entire duration. Depending on the nature of the financial instrument, the Company assesses whether credit risk is significantly increased on the basis of individual financial assets or a portfolio of financial assets. The Company divides notes receivable and accounts receivable into several combinations according to credit risk characteristics, and calculates expected credit losses on the basis of the combination. The basis for determining the combination is as follows: Accounts receivable Portfolio 1: combination of related parties within the scope of consolidation Accounts receivable Portfolio 2: aging portfolio Notes Receivable Portfolio 1: Banker's Acceptance receivable Notes Receivable Portfolio 2: Commercial Acceptance receivable For the accounts receivable divided into portfolios, the company, by referring to the historical credit loss experience, combined with the current situation and the forecast of future economic conditions, prepares the comparison table of the expected credit loss rate between the age of accounts receivable and the entire duration of accounts receivable to calculate the expected credit loss. For notes receivable divided into portfolios, the Company calculates expected credit losses based on default risk exposure and expected credit loss rate over the entire duration by referring to historical credit loss experience, combining current situation and forecast of future economic conditions. Accounts receivable -- a comparison of the aging of an aging portfolio with the expected credit 119 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 loss rate over its entire life Aging of account Expected credit loss rate of accounts receivable (%) Within 1 Year 1.00 1-2 Years 5.00 2-3 Years 10.00 3-4 Years 30.00 4-5 Years 50.00 More than 5 Years 100.00 ② Receivables and lease receivables with a significant financing component. For receivables with a significant financing component and for lease receivables regulated by Accounting Standard for Business Enterprises No. 21 - Leases, the Company measures the loss reserve in accordance with the general method known as the "three-stage" model. (3) Other methods of measuring loss reserves for financial assets For financial assets other than the above, such as debt investments, other debt investments, other receivables, long-term receivables other than lease receivables, the Company measures the loss reserve in accordance with the general method, namely the "three-stage" model. The Company takes the following factors into account when assessing whether credit risk is significantly increased in the event of credit impairment of the measurement financial instruments: The Company divides other receivables into several combinations according to the nature of the amounts, and calculates the expected credit loss on the basis of the combination. The basis for determining the combination is as follows: Other receivables Portfolio 1: Combination of related parties within the scope of consolidation Other receivables Portfolio 2: Financing margin portfolio Other receivables Portfolio 3: Export tax rebates receivable portfolio 2. Accounting for expected credit losses In order to reflect the changes of the credit risks of financial instruments since the initial recognition, the Company remeasures the expected credit losses on each balance sheet date, and the resulting increase in the loss reserve or reversal amount shall be recorded into the current profit and loss as impairment losses or gains. Write off the carrying value of the financial asset listed in the balance sheet or into the estimated liabilities or into other comprehensive income (debt investment measured at fair value and its changes into other comprehensive income). (XII) Inventories 1. Classification of inventory Inventory refers to finished products or commodities held by the Company in daily activities for sale, products in the process of production, materials and materials consumed in the process of production or provision of services, etc. It mainly includes raw materials, turnover materials (packaging, low-value consumable, etc.), commissioned processing materials, products in process, homemade semi-finished products, finished products (stock goods), etc. 2. Valuation method for issuing inventory When the inventory is dispatched, the monthly weighted average method is adopted to determine the actual cost of delivery. 3. Method of drawing reserve for inventory decline On the balance sheet date, the inventory shall be measured according to the lower of the cost and net realizable value, and the inventory decline reserve shall be calculated according to the single inventory item. However, for the inventory with a large quantity and a low unit price, the inventory decline reserve shall be calculated according to the inventory category. On the balance sheet date, the inventory shall be measured by the lower of cost and net realizable value, and the inventory depreciation reserve shall be calculated according to the difference between the cost of inventory class and net realizable value. The net realizable value of the inventory directly used for sale shall be determined by the estimated selling price of the inventory less estimated selling expenses and related taxes in the normal course of production and operation; For inventories that need to be processed, the net realizable value shall be determined by the estimated selling price of finished products produced in the normal course of production and operation after deducting the estimated cost, estimated selling expenses and related taxes to be incurred upon completion; On the balance sheet date, if a part of the same inventory has a contract price, but the other part does not have a contract 120 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 price, its net realizable value shall be determined respectively, and the corresponding cost shall be compared with it to determine the amount to be withdrawn or transferred back from the reserve for inventory declines respectively. 4. Inventory system The company's inventory system is the perpetual inventory system. 5. Amortization method of low-value consumable products and packaging Low - value consumable goods and packaging are amortized by one - pass method. (XIII) Contract assets and contract liabilities 1. Contract assets The Company presents as a contractual asset the right to receive consideration for goods or services transferred to the Customer, subject to factors other than the passage of time. Provision for impairment of contracted assets shall be made according to the expected credit loss method of financial instruments. For contract assets that do not contain a material financing component, the Company adopts a simplified method to measure loss provisions. For contract assets that contain significant financing components, the Company measures loss provisions in accordance with the general method. In case of impairment loss on contract assets, "asset impairment loss" shall be debited according to the amount to be written down, and the impairment provision for contract assets shall be credited; The reverse entry is made when the asset impairment provision has been transferred back. 2. Contract liabilities Obligations of the Company to transfer goods or services to the Customer for consideration received or receivable from the customer shall be listed as contractual liabilities. The Company presents contractual assets and contractual liabilities under the same contract on a net basis. (XIV) Long-term equity investments 1. Initial investment cost determination For the long-term equity investment obtained from the enterprise merger, if the enterprise merger is under the same control, the initial investment cost of the long-term equity investment shall be taken as the share of the owner's equity of the merged party in the book value of the final controlling party's consolidated financial statements on the merger date; In the case of enterprise merger not under the same control, the initial investment cost of long-term equity investment shall be taken as the merger cost determined on the purchase date; For long-term equity investment obtained by cash payment, the initial investment cost is the actual purchase price paid; For the long-term equity investment obtained by issuing equity securities, the initial investment cost shall be the fair value of the equity securities issued; The initial cost of long-term equity investment obtained through debt restructuring shall be determined in accordance with the relevant provisions of Accounting Standards for Enterprises “CASBE 12 – Debt Restructuring”; For long-term equity investment obtained by exchange of non- monetary assets, the initial investment cost shall be determined in accordance with relevant provisions of Accounting Standards for Business Enterprises “CASBE 7 – Non-cash Assets Exchange”. 2. Subsequent measurement and recognition method of profit or loss For long-term equity investments with control relationship, it is accounted for with cost method; for long-term equity investments with joint control or significant influence relationship, it is accounted for with equity method. The company for equity investment consortium, one part of through risk investment institutions, mutual funds, trust companies or similar subject, including cast the insurance fund, indirect holding, whether the above subject has a significant influence on this part of the investment, the company in accordance with the accounting standards for enterprises “CASBE 22 – Financial Instruments: Recognition and Measurement”, and the rest of the equity method accounting. 3. Determine the basis of joint control and significant influence on the invested entity Of the invested entity has joint control, refers to an arrangement returns have a significant impact 121 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 on activity must go through the participants agreed to share control decisions, including the sale and purchase of goods or services, financial assets management, purchase and disposal of the assets, research and development activities, and financing activities, etc.; Having a significant influence on the invested entity refers to having a significant influence when holding more than 20% to 50% of the voting capital of the invested entity. Or, although less than 20%, has a significant impact if one of the following conditions is met: representation on the board of directors or a similar authority of the invested entity; To participate in the policy making process of the investee; Dispatching management personnel to the invested units; The invested entity relies on the technology or technical data of the investment company; Having important transactions with the invested units. (XV) Investment property The Company's investment property categories, including leased land use rights, leased buildings, land use rights held and ready to be transferred after appreciation. The initial measurement of investment property is carried out according to the cost, and the subsequent measurement is carried out according to the cost model. The average life method is adopted for the depreciation of leased buildings in the Company's investment property, and the specific accounting policy is the same as that of fixed assets. The land- use right leased in investment property and the land-use right held and transferred after appreciation shall be amortized by the straight-line method. The specific accounting policies are the same as those for intangible assets. (XVI) Fixed assets 1. Recognition principles of fixed assets Fixed assets are tangible assets held for use in the production of goods or rendering of services, for rental to others, or for administrative purposes, and expected to be used during more than one accounting year. Fixed assets are recognized if, and only if, it is probable that future economic benefits associated with the assets will flow to the Company and the cost of the assets can be measured reliably. 2.Depreciation method of different categories of fixed assets The company's fixed assets are mainly divided into: buildings and structures, machinery, electronic equipment, transport facilities, etc. The depreciation method adopts the average life method. The service life and estimated net salvage value of fixed assets shall be determined according to the nature and usage of various types of fixed assets. At the end of the year, the service life, estimated net salvage value and depreciation method of the fixed assets shall be rechecked. If there is any difference from the original estimate, corresponding adjustment shall be made. In addition to the fixed assets that have been fully depreciated but are still in use and the land that is separately priced and recorded, the Company will calculate and depreciate all the fixed assets. Estimated residual value Annual depreciation rate Categories Useful life (years) proportion (%) (%) Buildings and structures 15-35 3.00 2.77-6.47 Machinery 10-15 3.00 6.47-9.70 Transport facilities 6-8 3.00 12.13-16.17 Electronic equipment 4-11 3.00 8.82-24.25 Other equipment 4-11 3.00 8.82-24.25 (XVII) Construction in progress 1. Construction in progress is recognized if, and only if, it is probable that future economic benefits associated with the item will flow to the Company, and the cost of the item can be measured reliably. Construction in progress is measured at the actual cost incurred to reach its designed usable conditions. 2. Construction in progress is transferred into fixed assets at its actual cost when it reaches the designed usable conditions. When the auditing of the construction in progress was not finished while reaching the designed usable conditions, it is transferred to fixed assets using estimated value first, and then adjusted accordingly when the actual cost is settled, but the accumulated depreciation is not 122 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 to be adjusted retrospectively. (XVIII) Borrowing costs 1. Recognition principle of capitalization of borrowing costs Borrowing costs incurred by the Company that can be directly attributed to the purchase, construction or production of assets eligible for capitalization shall be capitalized and included in the cost of relevant assets; Other borrowing costs shall be recognized as expenses according to the amount incurred when incurred and recorded into current profits and losses. The assets that meet the capitalization conditions refer to the fixed assets, investment real estate, inventory and other assets that need to go through a fairly long period of purchase, construction or production activities to reach the predetermined state of being usable or saleable. 2. Calculation method of capitalization amount Capitalization period refers to the period from the beginning of capitalization of borrowing costs to the end of capitalization. Periods of suspension of capitalization of borrowing costs are not included. Capitalization of borrowing costs shall be suspended if abnormal interruption occurs in the purchase, construction or production process and the interruption lasts for more than 3 consecutive months. The borrowing of a special loan shall be determined according to the amount of the interest expense actually incurred in the current period of the special loan, minus the interest income obtained from depositing the unused loan funds in the bank or the investment income obtained from temporary investment; Occupied general borrowings shall be calculated and determined according to the weighted average of the accumulated asset expenditure exceeding the portion of special borrowings multiplied by the capitalization rate of occupied general borrowings, and the capitalization rate shall be the weighted average interest rate of general borrowings; If there is a discount or premium on the loan, the amount of discount or premium to be amortized in each accounting period shall be determined according to the effective interest rate method, and the amount of interest for each period shall be adjusted. The effective interest rate method is a method to calculate the amortized discount or premium or interest expense of a loan according to the effective interest rate. The effective interest rate is the future cash flow of the loan during its expected life, discounted as the interest rate used in the current book value of the loan. (XIX) Intangible assets 1. The valuation method of intangible assets The Company's intangible assets are initially measured at cost. The purchased intangible assets shall be regarded as the actual cost according to the actual price paid and related expenses. The actual cost of intangible assets invested by investors shall be determined according to the value stipulated in the investment contract or agreement, but if the value stipulated in the contract or agreement is unfair, the actual cost shall be determined according to the fair value. For self-developed intangible assets, the cost shall be the total amount of expenses incurred before reaching the intended use. The Company's subsequent measurement methods for intangible assets are as follows: Intangible assets with limited service life shall be amortized by the straight-line method, and the service life and amortization method of intangible assets shall be rechecked at the end of the year. If there is any difference from the original estimate, corresponding adjustment shall be made; Intangible assets with uncertain service life are not amortized, but at the end of the year, the service life shall be rechecked. When there is conclusive evidence that the service life is limited, the service life shall be estimated and amortized according to the straight-line method. Intangible assets with limited useful life are amortized as follows: Items Amortization period (years) Software 3-10 patent right and non-patented technology 5-10 land use right 40-50 2. The judgment basis of uncertain service life The Company will not be able to foresee the period of time that the asset will bring economic benefits to the Company, or the intangible assets with uncertain service life are identified as intangible assets with uncertain service life. The judgment basis of uncertain service life is: it comes from 123 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 contractual rights or other legal rights, but the contract or legal provisions do not specify the service life; Based on the industry situation or relevant experts' arguments, it is still impossible to judge the period when intangible assets bring economic benefits to the company. At the end of each year, the service life of intangible assets with uncertain service life is reviewed, mainly in a bottom-up way. The departments related to the use of intangible assets conduct basic review to evaluate whether the judgment basis of uncertain service life has changed. 3. Specific criteria for research and development stages of internal research and development projects, as well as specific criteria for development stage expenditures to meet the capitalization conditions Expenditure in the research phase of internal research and development projects shall be recorded into current profits and losses when incurred; The expenditure in the development stage shall be transferred to the accounting of intangible assets if it meets the conditions of being recognized as intangible assets. Specific criteria for dividing the research phase and development phase of an internal research and development project: (1) it is technically feasible to complete the intangible asset so that it can be used or sold; (2) it has the intention to complete the intangible asset and use or sell it; (3) The way in which intangible assets generate economic benefits, including being able to prove that there is a market for the products produced by using the intangible assets or that there is a market for the intangible assets themselves, and that the intangible assets will be used internally, being able to prove their usefulness; (4) it has the support of sufficient technology, financial resources and other resources to complete the development of the intangible asset and has the ability to use or sell the intangible asset; (5) The expenditure attributable to the development stage of the intangible asset can be measured reliably. (XX) Impairment of part of long-term assets If long-term equity investment, investment real estate measured by the cost model, fixed assets, intangible assets of construction in progress and other long-term assets show signs of impairment on the balance sheet date, the impairment test shall be conducted. If the result of the impairment test shows that the recoverable amount of the asset is lower than its carrying value, the impairment reserve shall be calculated and booked into the impairment loss according to the difference. The recoverable amount is the higher between the net fair value of the asset less the disposal charge and the present value of the expected future cash flows of the asset. If it is difficult to estimate the recoverable amount of a single asset, the recoverable amount of the asset group shall be determined based on the asset group to which the asset belongs. An asset group is the smallest set of assets that can independently generate cash inflows. Goodwill shown separately in the financial statements, regardless of whether there is evidence of impairment, shall be tested for impairment at least annually. In the impairment test, the carrying value of goodwill is apportion to the group of assets or combination of asset groups expected to benefit from the synergies of the business combination. If the test results show that the recoverable amount of the asset group or the asset group combination containing the apportion of goodwill is lower than its carrying value, the corresponding impairment loss shall be recognized. The amount of impairment loss shall first offset the book value of goodwill apportion to the asset group or asset group combination, and then offset the book value of other assets in proportion to the proportion of the book value of assets other than goodwill in the asset group or asset group combination. Once the above-mentioned asset impairment loss is recognized, the part whose value can be recovered shall not be transferred back in the following period. (XXI) Long-term prepayments Long-term prepayments are expenses that have been recognized but with amortization period over one year (excluding one year). They are recorded with actual cost, and evenly amortized within the beneficiary period or stipulated period. If items of long-term prepayments fail to be beneficial to 124 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 the following accounting periods, residual values of such items are included in profit or loss. (XXII) Employee benefits Employee benefits refers to various forms of remuneration or compensation provided by the Company for obtaining services provided by employees or for terminating labor relations. Employee benefits include short-term employee benefits, post-employment benefits, termination benefits and other long-term employee benefits. 1. Short-term employee benefits During the accounting period when employees provide services for the company, the actual short- term compensation is recognized as liabilities and booked into the current profits and losses, except for those required or allowed to be booked into the cost of assets by the accounting standards for enterprises. The employee welfare expense incurred by the Company shall be included in the current profit and loss or the cost of relevant assets according to the actual amount when it is actually incurred. If the employee welfare fee is non-monetary welfare, it shall be measured at fair value. The company for the medical treatment insurance premium of worker pay, inductrial injury insurance, birth insurance premium of social insurance premiums and housing accumulation fund, and according to the rules extraction of the trade union and employee education funds and provide services in the workers of the accounting period, according to the provisions stipulated in the basic and provision ratio calculate and determine the corresponding compensation amount, and confirm corresponding liabilities, Include current profit or loss or related asset cost. 2. Post-employment benefits During the accounting period when employees provide services, the payable amount calculated according to the set depository plan shall be recognized as liabilities and recorded into the current profit and loss or the cost of relevant assets. According to the formula determined by the expected cumulative benefit unit method, the welfare obligation arising from the set benefit plan shall be attributed to the period of service provided by the employee, and shall be included in the current profit and loss or the cost of relevant assets. 3. Termination benefits Termination benefits provided to employees are recognized as an employee benefit liability for termination benefits, with a corresponding charge to profit or loss at the earlier of the following dates: a. when the Company cannot unilaterally withdraw the offer of termination benefits because of an employment termination plan or a curtailment proposal; or b. when the Company recognizes cost or expenses related to a restructuring that involves the payment of termination benefits. 4. Other long-term employee benefits Other long-term employee benefits provided by the company to the employees that meet the conditions for setting up an escrow plan shall be dealt with in accordance with the provisions on setting up an escrow plan; In addition, identify and measure other long-term employee benefit net liabilities or net assets according to the relevant provisions of the defined benefit plan. (XXIII) Provisions An obligation related to a contingent event is recognized as a projected liability when it is a current obligation undertaken by the Company and the performance of the obligation is likely to result in an outflow of economic benefits and the amount of the obligation can be measured reliably. The Company shall make initial measurement according to the best estimate of the expenditure required to fulfill the relevant current obligations. If there exists a continuous range of expenditure required and various outcomes within the range are equally likely to occur, the best estimate shall be determined as the intermediate value within the range; If more than one project is involved, calculate the best estimate based on the various possible outcomes and the associated probabilities. On the balance sheet date, the book value of the projected liabilities shall be reviewed. If there is conclusive evidence that the book value does not truly reflect the current best estimate, the book value shall be adjusted according to the current best estimate. (XXIV) Revenue The Company has fulfilled its performance obligation under the contract, that is, when the customer obtains control of the relevant commodity or service, it recognizes revenue according to the transaction price apportioned to the performance obligation. To acquire the control right of relevant goods refers to to be able to dominate the use of the goods and obtain almost all the 125 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 economic benefits from them. Performance obligation refers to the commitment of the company in the contract to transfer clearly distinguishable commodities to the customer. Transaction Price represents the amount of consideration that the Company expects to be entitled to collect as a result of the transfer of goods to the Customer, excluding monies received on behalf of third parties and monies that the Company expects to refund to the Customer. Whether the performance obligation is to be performed within a certain period of time or at a certain point depends on the terms of the contract and relevant legal provisions. If the performance obligation is performed within a certain period of time, the Company recognizes revenue according to the progress of performance. Otherwise, the Company recognizes revenue at a point at which the customer acquires control of the relevant assets. If one of the following conditions is met, the performance obligation shall be performed within a certain period of time; otherwise, the performance obligation shall be performed at a certain point: (1) The customer obtains and consumes the economic benefits arising from the Company's performance at the same time as the Company's performance; (2) The customer can control the goods under construction during the company's performance; (3) The commodities produced by the Company during the performance of the Contract have irreplaceable uses, and the Company has the right to collect payment for the accumulated performance completed so far throughout the contract period. For performance obligations performed within a certain period of time, the Company recognizes revenue in accordance with the progress of performance during that period. If the performance progress cannot be reasonably determined and the incurred costs are expected to be compensated, the revenue shall be recognized according to the amount of incurred costs until the performance progress can be reasonably determined. For performance obligations performed at a certain point, revenue is recognized at the point when the customer acquires control of the relevant goods or services. In determining whether the customer has acquired control of the goods, the Company considers the following indications: (1) the Company has a current collection right in respect of the goods, i.e. the customer has a current payment obligation in respect of the goods; (2) the Company has transferred the legal title of the goods to the Customer, that is, the customer has the legal title of the goods; (3) The Company has physically transferred the commodity to the customer, that is, the customer has physically possessed the commodity; (4) The Company has transferred the major risks and rewards in the ownership of the commodities to the Customer, that is, the customer has obtained the major risks and rewards in the ownership of the commodities; (5) The customer has accepted the goods; (6) Other signs indicating that the customer has acquired control of the goods. Specific methods of revenue recognition The Company mainly sells video conferencing products, integrated cabling products, intelligent electrical products, communication basic products and other products. The above product sales business of the company is a performance obligation performed at a certain point, and the product revenue recognition shall meet the following conditions: The company has delivered the products to the purchaser according to the contract and accepted them by the purchaser, and the amount of sales revenue of the products has been determined, the payment for goods has been recovered or the receipt of payment has been obtained, and the relevant economic benefits are likely to flow in, and the costs related to the products can be measured reliably. (XXV) Contract cost 126 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 The contract cost of the Company includes the incremental cost incurred to obtain the contract and the contract performance cost. Incremental costs incurred to acquire a contract (" contract acquisition costs ") are costs that would not have been incurred otherwise. If the cost is expected to be recovered, the Company will recognize it as a contract acquisition cost as an asset. The cost incurred by the Company to perform the contract, which does not fall within the scope of accounting standards for enterprises such as inventory and meets the following conditions at the same time, shall be recognized as an asset as the contract performance cost: 1. The costs are directly related to a current or expected contract and include direct labor, direct materials, manufacturing expenses (or similar expenses), costs expressly borne by the User and other costs incurred solely as a result of the contract; 2. The cost increases the Company's resources for future performance obligations; 3. This cost is expected to be recovered. The Company will recognize the contract performance costs as assets, the amortization period of the initial recognition does not exceed one year or a normal business cycle, in the balance sheet into the "inventory" item; If the amortization period is more than one year or one normal operating cycle at the time of initial recognition, "other non-current assets" will be included in the balance sheet. The Company shall record the acquired costs of contracts recognized as assets into the "other current assets" item in the balance sheet if the amortization period at the initial recognition does not exceed one year or one normal operating cycle. If the amortization period is more than one year or one normal operating cycle at the time of initial recognition, "other non-current assets" will be included in the balance sheet. The Company amortizes the assets recognized for contract acquisition cost and contract performance cost (hereinafter referred to as "assets related to contract cost") on the same basis as the commodity revenue recognized for the assets and records them into the current profit and loss. If the amortization period of the asset formed by the incremental cost of acquiring the contract does not exceed one year, it shall be included in the current profit and loss at the time of occurrence. If the carrying value of the asset related to the contract cost is higher than the difference between the following two items, the Company will calculate and withdraw the excess part of the impairment reserve and recognize it as the asset impairment loss: 1. The remaining consideration expected to be obtained from the transfer of commodities related to the asset; 2. Estimate the cost to be incurred for the transfer of the related goods. If the difference between the foregoing two items is higher than the carrying value of the asset due to the change of the factors of impairment in the previous period, it shall revert to the original provision for asset impairment and be included in the current profit and loss, provided that the carrying value of the asset after the reversal shall not exceed the carrying value of the asset on the date of reversal assuming no provision for impairment. (XXVI) Government grants 1. Types of government subsidies and accounting treatment Government subsidy refers to the monetary assets or non-monetary assets that the Company obtains free of charge from the government (but does not include the capital invested by the government as the owner). If the government subsidy is a monetary asset, it shall be measured according to the amount received or receivable. Where government subsidies are non-monetary assets, they shall be measured at fair value; If the fair value cannot be obtained reliably, it shall be measured according to the nominal amount. Government subsidies related to daily activities shall be included in other income according to the economic business essence. Government subsidies unrelated to daily activities shall be included 127 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 in non-operating income. Government documents clearly stipulate that government subsidies for the purchase and construction of long-term assets or the formation of long-term assets by other means shall be recognized as government subsidies related to assets. If the government documents do not specify the object of subsidy, and long-term assets can be formed, the part of government subsidy corresponding to the value of the asset shall be regarded as the government subsidy related to the asset, and the rest shall be regarded as the government subsidy related to the income. It is difficult to distinguish between government subsidies as a whole as government subsidies related to benefits. Government subsidies related to assets are recognized as deferred income. The amount recognized as deferred income shall be recorded into current profits and losses in a reasonable and systematic manner during the useful life of the relevant asset. Government subsidies other than those related to assets shall be recognized as government subsidies related to earnings. If the government subsidies related to earnings are used to compensate the relevant expenses or losses of the enterprise in the subsequent period, they shall be recognized as deferred earnings and recorded into the current profit and loss during the period when the relevant expenses are recognized. If it is used to compensate the relevant expenses or losses already incurred by the enterprise, it shall be directly recorded into the current profit and loss. If the company obtains a policy preferential loan discount interest, and the finance allocates the discount interest funds to the lending bank, and the lending bank provides the loan to the Company at the policy preferential interest rate, the actual amount of the loan is taken as the recorded value of the loan, and the relevant borrowing costs are calculated according to the loan principal and the policy preferential interest rate; If the finance directly appropriates the discount interest funds to the Company, the Company will offset the corresponding discount interest against the relevant borrowing costs. 2. Confirmation of government subsidies Government grants are recognized when the conditions attached to government grants are met and can be received. The government subsidy measured according to the amount receivable shall be confirmed at the end of the period when there is solid evidence that it can meet the relevant conditions stipulated in the financial support policy and is expected to receive the financial support funds. Government subsidies other than those measured according to the amount receivable shall be recognized when the amount of subsidies is actually received. (XXVII) Deferred income tax assets and liabilities 1. Deferred tax assets or deferred tax liabilities are calculated and recognized based on the difference between the carrying amount and tax base of assets and liabilities (and the difference of the carrying amount and tax base of items not recognized as assets and liabilities but with their tax base being able to be determined according to tax laws) and in accordance with the tax rate applicable to the period during which the assets are expected to be recovered or the liabilities are expected to be settled. 2. A deferred tax asset is recognized to the extent of the amount of the taxable income, which it is most likely to obtain and which can be deducted from the deductible temporary difference. At the balance sheet date, if there is any exact evidence that it is probable that future taxable income will be available against which deductible temporary differences can be utilized, the deferred tax assets unrecognized in prior periods are recognized. 3. Recognize deferred tax liabilities for taxable temporary differences related to investments in subsidiaries and associates, unless the Company has control over the timing of the reversal of the temporary differences and it is likely that the reversal will not occur in the foreseeable future. For deductible temporary differences related to investments in subsidiaries and associates, deferred tax assets are recognized when such temporary differences are likely to be reversed in the foreseeable future and the amount of taxable income used to offset the deductible temporary differences is likely to be obtained in the future. (XXVIII) Leases 1. Accounting treatment of leased assets On the commencement date of the lease term, the Company recognizes the right to use assets and lease liabilities for leases other than short-term leases and leases of low-value assets, and recognizes depreciation expense and interest expense, respectively, during the lease term. The Company uses the straight-line method for each period of the lease term to charge lease 128 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 payments for short-term leases and leases for low-value assets to current expenses. (1)Right-of-use asset The right-of-use asset is initially measured at cost, which includes: 1) the initial measurement amount of the lease liability; 2) the lease payments made on or before the start date of the lease term, if there is a lease incentive, deduct the amount of the lease incentive already enjoyed ; 3) Initial direct costs incurred by the lessee; 4) The lessee is expected to incur costs to dismantle and remove the leased asset, restore the site where the leased asset is located, or restore the leased asset to the state agreed upon in the lease terms The company depreciates right-of-use assets on a straight-line basis. If it can be reasonably determined that the ownership of the leased asset will be obtained at the expiration of the lease term, the company shall accrue depreciation over the remaining useful life of the leased asset. If it cannot be reasonably determined that the ownership of the leased asset can be obtained when the lease term expires, the company shall accrue depreciation within the shorter of the lease term and the remaining useful life of the leased asset. In accordance with the Accounting Standards for Enterprises “ CASBE 8 - Asset Impairment”, the company determines whether the assets used for use have been impaired and carries out accounting treatment. (2)Lease liability The lease liability is initially measured at the present value of the outstanding lease payments on the commencement date of the lease term. The lease payment amount includes: 1) the fixed payment amount (including the substantial fixed payment amount). If there is a lease incentive, the lease incentive related amount shall be deducted; 2) variable lease payments depending on the index or ratio; 3) the amount expected to be paid according to the security residual value provided by the lessee; 4) the exercise price of the purchase option, the premise is that the lessee is reasonable to determine the exercise of the option; 5) Payment for exercising the option to terminate the lease, provided that the lease term reflects that the lessee will exercise the option to terminate the lease; The Company uses the lease embedded interest rate as the discount rate; If it is impossible to reasonably determine the interest rate embedded in the lease, the incremental borrowing rate of the Company shall be used as the discount rate. The Company calculates the interest expense of the lease liability in each period of the lease term at a fixed periodic interest rate and records it as a financial expense. The cyclical rate refers to the discount rate or the revised discount rate adopted by the Company. Variable lease payments that are not included in the measurement of lease liabilities are recorded in current profit and loss when they are actually incurred. If the Company changes the evaluation result of the option to renew the lease, terminate the lease or purchase the lease, it will re-measure the lease liability according to the present value calculated by the changed lease payment amount and the revised discount rate, and adjust the book value of the right asset accordingly. In the event of a change in the actual lease payment, the estimated payable amount of the guarantee residual or the variable lease payment depending on the index or ratio, the lease liability shall be re-measured according to the present value calculated by the changed lease payment and the original discount rate, and the carrying value of the right asset shall be adjusted accordingly. 2. Accounting treatment of leased assets (1)Operating lease accounting treatment In each period of the lease term, the Company adopts the straight-line method to recognize the lease receipts from the operating leases as rental income. The Company capitalizes the initial direct expenses incurred in connection with the operating lease and stages them into current earnings during the lease term on the same basis of recognition as rental income. (2)Accounting treatment of finance lease On the lease commencement date, the Company recognizes the difference between the sum of the financial lease receivable, the unguaranteed residual value and its present value as unrealized 129 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 financing income, and recognizes it as lease income in each period in which the rent is received in the future. The initial direct expenses incurred by the Company in connection with the leasing transaction are included in the initial recorded value of the finance lease receivable. (XXIX) Explanation of changes in major accounting policies and accounting estimates Since the first implementation of Interpretation of Accounting Standards No. 15 in 2022, the Company has not involved the adjustment of the financial statements at the beginning of the first implementation year.

Risks related to financial instruments The Company aims to seek the appropriate balance between the risks and benefits from its use of financial instruments and to mitigate the adverse effects that the risks of financial instruments have on the Company’s financial performance. Based on such objectives, the Company’s risk management policies are established to identify and analyze the risks faced by the Company, to set 158 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 appropriate risk limits and controls, and to monitor risks and adherence to limits. The Company has exposure to the following risks from its use of financial instruments, which mainly include: credit risk, liquidity risk, and market risk. Management have deliberated and approved policies concerning such risks, and details are: (I) Credit risk Credit risk is the risk that one party to a financial instrument will cause a financial loss for the other party by failing to discharge an obligation. 1. Credit risk management practice (1) Evaluation method of credit risk At each reporting date, the Company assesses whether the credit risk on a financial instrument has increased significantly since initial recognition. When assessing whether the credit risk has increased significantly since initial recognition, the Company takes into account reasonable and supportable information, which is available without undue cost or effort, including qualitative and quantitative analysis based on historical data, external credit risk rating, and forward-looking information. The Company determines the changes in default risk of financial instruments during the estimated lifetime through comparison of the default risk at the balance sheet date and the initial recognition date, on an individual basis or a collective basis. The Company considers the credit risk on a financial instrument has increased significantly when one or more of the following qualitative and quantitative standards are met: 1) Quantitative standard mainly relates to the scenario in which, on the balance sheet date, the probability of default in the remaining lifetime has risen by more than a certain percentage compared with the initial recognition; 2) Qualitative standard mainly relates to significant adverse changes in the debtor’s operation or financial position, present or expected changes in technology, market, economy or legal environment that will have significant adverse impact on the debtor’s repayment ability; (2) Definition of default and credit-impaired asset The Company defines a financial asset as in default when the financial instrument meets one or more of the following criteria, which are consistent with the definition of credit impairment incurred: 1) significant financial difficulty of the debtor; 2) a breach of binding clause of contract; 3) it is very likely that the debtor will enter bankruptcy or other financial reorganization; 4) the creditor of the debtor, for economic or contractual reasons relating to the debtor’s financial difficulty, having granted to the debtor a concession(s) that the creditor would not otherwise consider. 2. Measurement of expected credit losses The key factors in the measurement of expected credit loss include the probability of default, loss rate of default, and exposure to default risk. 3. The opening balance and closing balance of loss provision for financial instruments are detailed in Notes V(3), V(4) and V(7) to these financial statements. 4. Exposure to credit risk and concentration of credit risk The Company’s credit risk is primarily attributable to cash and bank balances and receivables. In order to control such risks, the Company has taken the following measures: (1) Cash and bank balances 159 Nanjing Putian Telecommunications Co., Ltd. Notes to Financial Statements 2022/1/1—2022/12/31 The Company deposits its bank balances and other cash and bank balances in financial institutions with relatively high credit levels, hence, its credit risk is relatively low. (2) Receivables The Company performs credit assessment on customers who uses credit settlement on a regular/continuous basis. The Company selects credible and well-reputed customers based on credit assessment result, and conducts ongoing monitoring on receivables, to avoid significant risks in bad debts. As the Company's accounts receivable risk points are distributed across multiple partners and multiple customers, 12.50% of the Company's accounts receivable as of June 30, 2022 (June 30, 2021:11.43%) originated from the top five customers with balances, and the Company does not have significant credit concentration risk. The maximum amount of exposure to credit risk of the Company is the carrying amount of each financial asset on the balance sheet. (II) Liquidity risk Liquidity risk is the risk that the Company may encounter deficiency of funds in meeting obligations associated with cash or other financial assets settlement, which is possibly attributable to failure in selling financial assets at fair value on a timely basis, or failure in collecting liabilities from counterparts of contracts, or early redemption of debts, or failure in achieving estimated cash flows. In order to control such risk, the Company utilized financing tools such as notes settlement, bank borrowings, etc. and adopts long and short financing methods to optimizing financing structures, and finally maintains a balance between financing sustainability and flexibility. The Company has obtained credit limit from several commercial Nanjing Putian Telecommunications Co., Ltd. 2021 Annual Report 187 banks to meet working capital requirements and expenditures.

Interest risk Interest risk is the risk that an enterprise may encounter fluctuation in fair value of financial instruments or future cash flows due to changes in market interest. The Company’s fair value interest risks arise from fixed-rate financial instruments, while the cash flow interest risks arise from floating interest financial instruments. The Company determines the proportion of fixed-rate financial instruments and floating interest rate financial instruments based on the market environment, and maintains a proper financial instruments portfolio through regular review and monitoring. The Company’s interest risk relates mainly to bank borrowings with floating interest rate 2. Foreign currency risk Foreign exchange risk refers to the risk that the fair value or future cash flow of a financial instrument may fluctuate due to changes in foreign exchange rates. The Company operates in mainland China and its main activities are denominated in renminbi, so the Company's exposure to foreign exchange movements is not material. The Company's foreign currency monetary assets and liabilities at the end of the period are detailed in the relevant notes to the financial statements. IX.
