Recognition criteria, measurement method and derecognition condition of financial assets and financial liabilities (1) Recognition criteria and measurement method of financial assets and financial liabilities When the Company becomes a party to a financial instrument, it is recognized as a financial asset or financial liability. The financial assets and financial liabilities initially recognized by the Company are measured at fair value; for the financial assets and liabilities at fair value through profit or loss, the transaction expenses thereof are directly included in profit or loss; for other categories of financial assets and financial liabilities, the transaction expenses thereof are included into the initially recognized amount. However, at initial recognition, for accounts receivable that do not contain a significant financing component or contracts in which the financing components with associated period less than one year are not considered, the Company measures at their transaction price in accordance with “CASBE 14 – Revenues”. (2) Subsequent measurement of financial assets 1) Financial assets measured at amortized cost The Company measures its financial assets at the amortized costs using effective interest method. Gains or losses on financial assets that are measured at amortized cost and are not part of hedging relationships shall be included into profit or loss when the financial assets are derecognized, reclassified, amortized using effective interest method or recognized with impairment loss. 2) Debt instrument investments at fair value through other comprehensive income The Company measures its debt instrument investments at fair value. Interests, impairment gains or losses, and gains and losses on foreign exchange that calculated using effective interest method shall be included into profit or loss, while other gains or losses are included into other comprehensive income.

Dividends obtained (other than those as part of investment cost recovery) shall be included into profit or loss, while other gains or losses are included into other comprehensive income.

Gains or losses arising from changes in fair value (including interests and dividends) shall be included into profit or loss, except for financial assets that are part of hedging relationships. (3) Subsequent measurement of financial liabilities 1) Financial liabilities at fair value through profit or loss Financial liabilities at fair value through profit or loss include held-for-trading financial liabilities (including derivatives that are liabilities) and financial liabilities designated as at fair value through profit or loss. The Company measures such kind of liabilities at fair value. The amount of changes in the fair value of the financial liabilities that are attributable to changes in the Company’s own credit risk shall be included into other comprehensive income, unless such treatment would create or enlarge accounting mismatches in profit or loss. Other gains or losses on those financial liabilities (including interests, changes in fair value that are attributable to reasons other than changes in the Company’s own credit risk) shall be included into profit or loss, except for financial liabilities that are part of hedging relationships. Accumulated gains or losses that originally recognized as other comprehensive income should be transferred out into retained earnings when the financial liabilities are derecognized. 2) Financial liabilities that arise when a transfer of a financial asset does not qualify for derecognition or when the continuing involvement approach applies The Company measures its financial liabilities in accordance with “CASBE 23 – Transfer of Financial Assets”. 3) Financial guarantee contracts not fall within the above categories 1) and 2), and commitments to provide a loan at a below-market interest rate, which do not fall within the above category 1) The Company measures its financial liabilities at the higher of: a. the amount of loss - 19 - allowances in accordance with impairment requirements of financial instruments; b. the amount initially recognized less the amount of accumulated amortization recognized in accordance with “CASBE 14 – Revenues”. 4) Financial liabilities at amortized cost The Company measures its financial liabilities at amortized cost using effective interest method. Gains or losses on financial liabilities that are measured at amortized cost and are not part of hedging relationships shall be included into profit or loss when the financial liabilities are derecognized and amortized using effective interest method. (4) Derecognition of financial assets and financial liabilities 1) Financial assets are derecognized when: a. the contractual rights to the cash flows from the financial assets expire; b. the financial assets have been transferred and the transfer qualifies for derecognition in accordance with “CASBE 23 – Transfer of Financial Assets”. 2) Only when the underlying present obligations of a financial liability are relieved totally or partly may the financial liability be derecognized accordingly. 3. Recognition criteria and measurement method of financial assets transfer Where the Company has transferred substantially all of the risks and rewards related to the ownership of the financial asset, it derecognizes the financial asset, and any right or liability arising from such transfer is recognized independently as an asset or a liability. If it retained substantially all of the risks and rewards related to the ownership of the financial asset, it continues recognizing the financial asset. Where the Company does not transfer or retain substantially all of the risks and rewards related to the ownership of a financial asset, it is dealt with according to the circumstances as follows respectively: (1) if the Company does not retain its control over the financial asset, it derecognizes the financial asset, and any right or liability arising from such transfer is recognized independently as an asset or a liability; (2) if the Company retains its control over the financial asset, according to the extent of its continuing involvement in the transferred financial asset, it recognizes the related financial asset and recognizes the relevant liability accordingly. If the transfer of an entire financial asset satisfies the conditions for derecognition, the difference between the amounts of the following two items are included in profit or loss: (1) the - 20 - carrying amount of the transferred financial asset as of the date of derecognition; (2) the sum of consideration received from the transfer of the financial asset, and the accumulative amount of the changes of the fair value originally included in other comprehensive income proportionate to the transferred financial asset (financial assets transferred refer to debt instrument investments at fair value through other comprehensive income). If the transfer of financial asset partially satisfies the conditions to derecognition, the entire carrying amount of the transferred financial asset is, between the portion which is derecognized and the portion which is not, apportioned according to their respective relative fair value, and the difference between the amounts of the following two items are included into profit or loss: (1) the carrying amount of the portion which is derecognized; (2) the sum of consideration of the portion which is derecognized, and the portion of the accumulative amount of the changes in the fair value originally included in other comprehensive income which is corresponding to the portion which is derecognized (financial assets transferred refer to debt instrument investments at fair value through other comprehensive income). 4. Fair value determination method of financial assets and liabilities The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value. The inputs to valuation techniques used to measure fair value are arranged in the following hierarchy and used accordingly: (1) Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company can access at the measurement date. (2) Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: quoted prices for similar assets or liabilities in active Nanjing Putian Telecommunications Co., Ltd. 2021 Annual Report 138 markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability, for example, interest rates and yield curves observable at commonly quoted intervals; market-corroborated inputs; (3) Level 3 inputs are unobservable inputs for the asset or liability. Level 3 inputs include interest rate that is not observable and cannot be corroborated by observable market data at commonly quoted intervals, historical volatility, future cash flows to be paid to fulfill the disposal - 21 - obligation assumed in business combination, and financial forecast developed using the Company’s own data, etc. 5. Impairment of financial instruments (1) Measurement and accounting treatment The Company, on the basis of expected credit loss, recognizes loss allowances of financial assets at amortized cost, debt instrument investments, contract assets or leases receivable at fair value through other comprehensive income, loan commitments other than financial liabilities at fair value through profit or loss, financial guarantee contracts not belong to financial liabilities at fair value through profit or loss or financial liabilities that arise when a transfer of a financial asset does not qualify for derecognition or when the continuing involvement approach applies. Expected credit losses refer to the weighted average of credit losses with the respective risks of a default occurring as the weights. Credit loss refers to the difference between all contractual cash flows that are due to the Company in accordance with the contract and all the cash flows that the Company expects to receive (i.e. all cash shortfalls), discounted at the original effective interest rate. Among which, purchased or originated credit-impaired financial assets are discounted at the credit- adjusted effective interest rate. At the balance sheet date, the Company shall only recognize the cumulative changes in the lifetime expected credit losses since initial recognition as a loss allowance for purchased or originated credit-impaired financial assets. For accounts receivable and contract assets that do not contain a significant financing component or financing components in contracts with associated period less than one year that are not considered by the Company, which result from transactions as regulated in ―CASBE 14 – Revenues‖, the Company chooses simplified approach to measure the loss allowance at an amount equal to lifetime expected credit losses. For financial assets other than the above, on each balance sheet date, the Company shall assess whether the credit risk on the financial instrument has increased significantly since initial recognition. The Company shall measure the loss allowance for the financial instrument at an amount equal to the lifetime expected credit losses if the credit risk on that financial instrument has - 22 - increased significantly since initial recognition; otherwise, the Company shall measure the loss allowance for that financial instrument at an amount equal to 12-month expected credit loss. Considering reasonable and supportable forward-looking information, the Company compares the risk of a default occurring on the financial instrument as at the balance sheet date with the risk of a default occurring on the financial instrument as at the date of initial recognition, so as to assess whether the credit risk on the financial instrument has increased significantly since initial recognition. The Company may assume that the credit risk on a financial instrument has not increased significantly since initial recognition if the financial instrument is determined to have relatively low credit risk at the balance sheet date. The Company shall estimate expected credit risk and measure expected credit losses on an individual or a collective basis. When the Company adopts the collective basis, financial instruments are grouped with similar credit risk features. The Company shall remeasure expected credit loss on each balance sheet date, and increased or reversed amounts of loss allowance arising therefrom shall be included into profit or loss as impairment losses or gains. For a financial asset measured at amortized cost, the loss allowance reduces the carrying amount of such financial asset presented in the balance sheet; for a debt investment measured at fair value through other comprehensive income, the loss allowance shall be recognized in other comprehensive income and shall not reduce the carrying amount of such financial asset.

Offsetting financial assets and financial liabilities Financial assets and financial liabilities are presented separately in the balance sheet and are not offset. However, the Company offsets a financial asset and a financial liability and presents the net amount in the balance sheet when, and only when, the Company: (a) currently has a legally enforceable right to set off the recognized amounts; and (b) intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously. For a transfer of a financial asset that does not qualify for derecognition, the Company does not offset the transferred asset and the associated liability. (XI) Inventories 1. Classification of inventories Inventories include finished goods or goods held for sale in the ordinary course of business, - 24 - work in process in the process of production, and materials or supplies etc. to be consumed in the production process or in the rendering of services. 2. Accounting method for dispatching inventories: Inventories dispatched from storage are accounted for with weighted average method. 3. Basis for determining net realizable value At the balance sheet date, inventories are measured at the lower of cost and net realizable value; provisions for inventory write-down are made on the excess of its cost over the net realizable value. The net realizable value of inventories held for sale is determined based on the amount of the estimated selling price less the estimated selling expenses and relevant taxes and surcharges in the ordinary course of business; the net realizable value of materials to be processed is determined based on the amount of the estimated selling price less the estimated costs of completion, selling expenses and relevant taxes and surcharges in the ordinary course of business; at the balance sheet date, when only part of the same item of inventories have agreed price, their net realizable value is determined separately and is compared with their costs to set the provision for inventory write-down to be made or reversed. 4. Inventory system Perpetual inventory method is adopted. 5. Amortization method of low-value consumables and packages (1) Low-value consumables Low-value consumables are amortized with one-off method. (2) Packages Packages are amortized with one-off method. (XII) 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 - 25 - 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. (XIII) 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; - 26 - 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 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. (XIV) Investment property Investment property includes land use right of leased-out property and buildings that have been leased out. The initial measurement of investment property is based on its cost, and subsequent measurement is made using the cost model, the depreciation or amortization method is the same as that of fixed assets. (XV) 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 - 27 - 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 Electronic equipment 4-11 3.00 8.82-24.25 Transport facilities 6-8 3.00 12.13-16.17 Other equipment 4-11 3.00 8.82-24.25 (XVI) 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 to be adjusted retrospectively. (XVII) Intangible assets 1. The valuation method of intangible assets - 28 - 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) Amortization method Software 3-10 straight-line method patent right and non-patented 5-10 straight-line method technology land use right 40-50 straight-line method 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 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. - 29 - 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. (XVIII) 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. - 30 - (XIX) 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 the following accounting periods, residual values of such items are included in profit or loss. (XX) 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 - 31 - 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. (XXI) 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. (XXII) Revenue 1. Revenue recognition principles At contract inception, the Company shall assess the contracts and shall identify each performance obligation in the contracts, and determine whether the performance obligation should be satisfied over time or at a point in time. - 32 - The Company satisfies a performance obligation over time if one of the following criteria is met, otherwise, the performance obligation is satisfied at a point in time: (1) the customer simultaneously receives and consumes the economic benefits provided by the Company’s performance as the Company performs; (2) the customer can control goods as they are created by the Company’s performance; (3) goods created during the Company’s performance have irreplaceable uses and the Company has an enforceable right to receive the payments for performance completed to date during the whole contract period. For each performance obligation satisfied over time, the Company shall recognize revenue over time by measuring the progress towards complete satisfaction of that performance obligation. In the circumstance that the progress cannot be measured reasonably, but the costs incurred in satisfying the performance obligation are expected to be recovered, the Company shall recognize revenue only to the extent of the costs incurred until it can reasonably measure the progress. For each performance obligation satisfied at a point in time, the Company shall recognize revenue at the time point that the client obtains control of relevant goods or services. To determine whether the customer has obtained control of goods, the Company shall consider the following indications: (1) the Company has a present right to payment for the goods, i.e., the customer is presently obliged to pay for the goods; (2) the Company has transferred the legal title of the goods to the customer, i.e., the customer has legal title to the goods; (3) the Company has transferred physical possession of the goods to the client, i.e., the customer has physically possessed the goods; (4) the Company has transferred significant risks and rewards of ownership of the goods to the client, i.e., the customer has obtained significant risks and rewards of ownership of the goods; (5) the customer has accepted the goods; (6) other evidence indicating the customer has obtained control over the goods. 2. Revenue measurement principle (1) Revenue is measured at the amount of the transaction price that is allocated to each performance obligation. The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer, excluding amounts collected on behalf of third parties and those expected to be refunded to the customer. (2) If the consideration promised in a contract includes a variable amount, the Company shall - 33 - confirm the best estimate of variable consideration at expected value or the most likely amount. However, the transaction price that includes the amount of variable consideration only to the extent that it is high probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. (3) In the circumstance that the contract contains a significant financing component, the Company shall determine the transaction price based on the price that a customer would have paid for if the customer had paid cash for obtaining control over those goods or services. The difference between the transaction price and the amount of promised consideration is amortized under effective interest method over contractual period. The effects of a significant financing component shall not be considered if the Company expects, at the contract inception, that the period between when the customer obtains control over goods or services and when the customer pays consideration will be one year or less. (4) For contracts containing two or more performance obligations, the Company shall determine the stand-alone selling price at contract inception of the distinct good underlying each performance obligation and allocate the transaction price to each performance obligation on a relative stand-alone selling price basis. 3. Revenue recognition method The Company’s main product is the Video conference products, integrated wiring products, low voltage distribution products, wiring products and other products. The above-mentioned product sales business of the company belongs to the performance obligation performed at a certain time point, and the revenue is recognized when the customer collects, has collected the price or obtained the right to collect and the relevant economic benefits are likely to flow in. (XXIII) Contract cost 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. - 34 - 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. - 35 - 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. (XXIV) 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 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 - 36 - 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. (XXV) 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. - 37 - 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. (XXVI) 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 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 - 38 - 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 - 39 - 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 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. (XXVII) Held for Sale and discontinued operations The Company classifies non-current assets or disposal groups that simultaneously meet the following conditions into the holding for Sale category: first, in accordance with the practice of selling such assets or disposal groups in similar transactions, they can be sold immediately under current conditions; Second, a sale is highly likely to occur, that is, the company has made a decision on a sale plan and obtained firm purchase commitments, and the sale is expected to be completed within a year. If the relevant regulations require the approval of the relevant authority or regulatory department before the enterprise can be sold, the approval shall have been obtained. Initial measurement or on the balance sheet date to measure hold illiquid assets for sale or disposal of the group, its book value is higher than the fair value minus the net amount after sale cost, book value shall be written down to fair value minus the net amount after selling fees, the amount of write-down shall be recognized as asset impairment losses recorded into the profits and losses of the current, the provision for assets impairment provision holds for sale at the same time. Non-current assets held for sale in the balance sheet or assets in the disposal group held for sale are listed as assets held for sale, and liabilities in the disposal group held for sale are listed as liabilities held for sale. A discontinued operation is a separately distinguishable component that meets one of the following conditions and has been disposed of by the Company or is classified by the Company as being held for sale: 1.The component represents a separate principal business or a separate principal area of - 40 - operation; 2.The component is part of an associated plan to dispose of a separate principal business or a separate principal territory of operations; 3.This component is a subsidiary acquired exclusively for resale. (XXVIII) Other significant accounting policies and estimates Including but not limited to: Termination of business confirmation standard, the accounting methods, adopting the hedging accounting basis and accounting methods, hedging effectiveness evaluation methods, the company's risk management strategy and how to apply the strategies to manage risk, accounting methods related to repurchase shares, asset securitization business accounting methods and so on. Explanation of major changes in accounting policies and accounting estimates: There are no changes in accounting policies and estimates during the current period; IV. Taxes (I) Main taxes and tax rates Taxes Tax bases Tax rates The output tax shall be calculated on the basis of the sales of goods and Value-added tax taxable service income calculated in accordance with the provisions of 13%、6%、5%、3% (VAT) the tax law.

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 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 - 72 - 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 beginning balance and ending balance of loss provision for financial instruments are - 73 - 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 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. - 74 - Financial instruments classified based on remaining time period till maturity Closing balance Items Carrying Contract amount Within 1 year 1-3 years Over 3 years amount not yet discounted Short-term 226,300,000.00 226,300,000.00 226,300,000.00 borrowings Notes payable 1,250,000.00 1,250,000.00 1,250,000.00 Accounts 478,365,312.80 478,365,312.80 478,365,312.80 payable Other payable 66,204,911.49 66,204,911.49 66,204,911.49 Long-term payable Non-current liabilities due within one year Subtotal 772,120,224.29 772,120,224.29 772,120,224.29 (Continued) Opening balance Items Carrying Contract amount Within 1 year 1-3 years Over 3 years amount not yet discounted Short-term 199,000,000.00 203,055,109.72 203,055,109.72 borrowings Notes payable 1,251,741.17 1,251,741.17 1,251,741.17 Accounts 538,363,742.94 538,363,742.94 538,363,742.94 payable Other payable 64,006,795.08 64,006,795.08 64,006,795.08 Long-term payable Non-current liabilities due 2,656,474.95 2,717,664.49 2,717,664.49 within one year Subtotal 805,278,754.14 809,395,053.40 809,395,053.40 (III) Market risk Market risk is the risk that the Company may encounter fluctuation in fair value of financial instruments or future cash flows due to changes in market price. 1. 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 - 75 - 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.
