The consolidated financial statements of the Group have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”). Significant accounting policies followed by the Group in the preparation of the accompanying consolidated financial statements are summarized below.

The consolidated financial statements include the financial statements of the Company, its subsidiaries, the VIEs and subsidiary of the VIEs for which the Company or its subsidiary is the primary beneficiary.

A subsidiary is an entity in which the Company, directly or indirectly, controls more than one half of the voting power; or has the power to appoint or remove the majority of the members of the Board of Directors; or to cast a majority of votes at the meeting of directors; or has the power to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders.

A consolidated VIE is an entity in which the Company, or its subsidiary, through contractual arrangements, has the power to direct the activities that most significantly impact the entity’s economic performance, bears the risks of and enjoys the rewards normally associated with ownership of the entity, and therefore the Company or its subsidiary is the primary beneficiary of the entity.

All transactions and balances among the Company, its subsidiaries, the VIEs and subsidiaries of the VIEs have been eliminated upon consolidation.

The following is a summary of the contractual agreements (collectively, “Contractual Agreements”) between the Company’s PRC subsidiary, Shen Si, and the VIEs. Through the Contractual Agreements, the VIEs are effectively controlled by the Company.

Shareholders’ Voting Rights Proxy Agreements. Pursuant to the Shareholders’ Voting Rights Proxy Agreements, each shareholder of VIEs irrevocably authorized Shen Si or any person(s) designated by Shen Si to exercise such shareholder’s rights in VIEs, including without limitation, the power to participate in and vote at shareholder’s meetings, the power to nominate and appoint the directors, senior management, and other shareholders’ voting right permitted by the articles of association of VIEs. The shareholders’ voting rights proxy agreements remain irrevocable and continuously valid from the date of execution until the expiration of the business term of Shen Si and can be renewed upon request by Shen Si.

Business Operation Agreements. Pursuant to the Business Operation Agreements, VIEs and their shareholders undertake that without Shen Si’s prior written consent, VIEs shall not enter into any transactions that may have a material effect on VIEs’ assets, business, personnel, obligations, rights or business operations. VIEs and their shareholders shall elect directors nominated by Shen Si and such directors shall nominate officers designated by Shen Si. The business operation agreements will remain effective until the end of Shen Si’s business term, which will be extended if Shen Si’s business term is extended or as required by Shen Si.

Equity Interest Pledge Agreements. Pursuant to the Equity Interest Pledge Agreements, each shareholder of VIEs agrees that, during the term of the Equity Interest Pledge Agreements, he or she will not dispose of the pledged equity interests or create or allow any encumbrance on the pledged equity interests without the prior written consent of Shen Si. The Equity Interest Pledge Agreements remain effective until the latter of the full payment of all secured debt under the equity interest pledge agreements and VIEs and their shareholders discharge all their obligations under the contractual arrangements.

Exclusive Technology Consulting and Services Agreements. Under the Exclusive Technology Consulting and Services Agreements between Shen Si and the VIEs, Shen Si has the exclusive right to provide VIEs with technology consulting and services related to, among other things, technology research and development, technology application and implementation, maintenance of software and hardware. Without Shen Si’s written consent, VIEs shall not accept any technology consulting and services covered by these agreements from any third party. VIEs agree to pay a service fee at an amount equivalent to all of its net profit to Shen Si. Unless otherwise terminated in accordance with the terms of these agreements or otherwise agreed with Shen Si, these agreements will remain effective until the expiration of Shen Si’s business term, and will be renewed if Shen Si’s business term is extended.

Exclusive Option Agreements. Pursuant to the Exclusive Option Agreements, each shareholder of VIEs has irrevocably granted Shen Si an exclusive option, to the extent permitted by PRC laws, to purchase, or have its designated person or persons to purchase, at its discretion, all or part of the shareholder’s equity interests in VIEs. Unless PRC laws and/or regulations require valuation of the equity interests, the purchase price shall be RMB1.00 or the lowest price permitted by the applicable PRC laws, whoever is higher. Each shareholder of VIEs undertakes that, without the prior written consent of Shen Si, he or she will not, among other things, (i) create any pledge or encumbrance on his or her equity interests in VIEs, (ii) transfer or otherwise dispose of his or her equity interests in VIEs, (iii) change VIEs’ registered capital, (iv) amend VIEs’ articles of association, (v) liquidate or dissolve VIEs, or (vi) distribute dividends to the shareholders of VIEs. In addition, VIEs undertake that, without the prior written consent of Shen Si, they will not, among other things, dispose of VIEs’ material assets, provide any loans to any third parties, enter into any material contract with a value of more than RMB500,000, or create any pledge or encumbrance on any of their assets, or transfer or otherwise dispose of their material assets. Unless otherwise terminated by Shen Si, these agreements will remain effective until the expiration of Shen Si’s business term, and will be renewed if Shen Si’s business term is extended.

The following table sets forth the assets, liabilities, results of operations and changes in cash and cash equivalents of the VIEs and their subsidiary taken as a whole, which were included in the Group’s consolidated financial statements with intercompany balances and transactions eliminated between the VIEs and their subsidiary:

Under the Contractual Agreements with the VIEs, the Company has the power to direct activities of the VIEs and VIEs’ subsidiaries, and can have assets transferred out of the VIEs and VIEs’ subsidiaries. Therefore, the Company considers itself the ultimate primary beneficiary of the VIEs and there is no asset of the VIEs that can only be used to settle obligations of the VIEs and VIEs’ subsidiaries, except for registered capital of the VIEs and their subsidiary amounting to RMB10 million as of December 31, 2018, 2019 and 2020, respectively. Since the VIEs are incorporated as limited liability companies under the PRC Company Law, creditors of the VIEs do not have recourse to the general credit of the Company. There is currently no contractual arrangement that would require the Company to provide additional financial support to the VIEs. However, as the Company is conducting certain businesses through its VIEs and VIEs’ subsidiary, the Company may provide such support on a discretionary basis in the future, which could expose the Company to a loss.

In the opinion of the Company's management, the contractual arrangements among its subsidiary, the VIEs and their respective Nominee Shareholders are in compliance with current PRC laws and are legally binding and enforceable. However, uncertainties in the interpretation and enforcement of the PRC laws, regulations and policies could limit the Company’s ability to enforce these contractual arrangements. As a result, the Company may be unable to consolidate the VIEs and VIEs’ subsidiaries in the consolidated financial statements.

On March 15, 2019, the Foreign Investment Law was formally passed by the thirteenth National People’s Congress and it was taken effect on January 1, 2020. The Foreign Investment Law replaces the Law on Sino-Foreign Equity Joint Ventures, the Law on Sino-Foreign Cooperative Joint Ventures and the Law on Foreign-Capital Enterprises to become the legal foundation for foreign investment in the PRC.

The Foreign Investment Law stipulates certain forms of foreign investment. However, the Foreign Investment Law does not explicitly stipulate contractual arrangements such as those we rely on as a form of foreign investment. Notwithstanding the above, the Foreign Investment Law stipulates that foreign investment includes “foreign investors investing through any other methods under laws, administrative regulations or provisions prescribed by the State Council.” Future laws, administrative regulations or provisions prescribed by the State Council may possibly regard Contractual Arrangements as a form of foreign investment. In the event that the State Council in the future promulgates laws and regulations that deem investments made by foreign investors through contractual arrangements as “foreign investment”, the Group’s ability to use the contractual arrangements with its VIEs and the Group’s ability to conduct business through the VIEs could be severely limited.

The Company’s ability to control the VIEs also depends on the power of attorney Shen Si has to vote on all matters requiring shareholders’ approvals in the VIEs. As noted above, the Company believes these power of attorney are legally binding and enforceable but may not be as effective as direct equity ownership. In addition, if the Group’s corporate structure or the contractual arrangements with the VIEs were found to be in violation of any existing PRC laws and regulations, the PRC regulatory authorities could, within their respective jurisdictions:

The imposition of any of these restrictions or actions may result in a material adverse effect on the Group’s ability to conduct its business. In addition, if the imposition of any of these restrictions causes the Group to lose the right to direct the activities of the VIEs or the right to receive their economic benefits, the Group would no longer be able to consolidate the financial statements of the VIEs. In the opinion of management, the likelihood of losing the benefits in respect of the Group’s current ownership structure or the contractual arrangements with its VIEs is remote.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, related disclosures of contingent assets and liabilities at the balance sheet date, and the reported revenues, costs and expenses during the reported period in the consolidated financial statements and accompanying notes. These accounting estimates reflected in the Group’s consolidated financial statements mainly include, but are not limited to, the estimation of the incentive program standalone selling price of the points and coupons, the valuation and recognition of share-based compensation arrangements, depreciable lives of property and equipment, useful life of intangible assets, expected credit losses on financial instruments, assessment for impairment of equity method investment, present value for expected future leasing payment, contingency reserve, provision of income tax and valuation allowance for deferred tax asset. Actual results could differ from those estimates.

Comprehensive Income and Foreign Currency Translation

The Group’s operating results are reported in the consolidated statements of comprehensive income pursuant to FASB ASC Topic 220, “Comprehensive Income”. Comprehensive income consists of two components: net income and other comprehensive income (“OCI”). The Group’s OCI is comprised of gains and losses resulting from translating foreign currency financial statements of entities, of which functional currency is other than Hong Kong dollar which is the presentational currency of the Group, net of related income taxes, where applicable. Such subsidiaries’ assets and liabilities are translated into Hong Kong dollars at period-end exchange rates, and revenues and expenses are translated at average exchange rates prevailing during the period. Adjustments that result from translating amounts from a subsidiary’s functional currency to the Hong Kong dollar (as described above) are reported net of tax, where applicable, in accumulated OCI in the consolidated balance sheets.

Convenience Translation

Translations of balances in the consolidated balance sheets, consolidated statements of comprehensive income and consolidated statements of cash flows from HK$ into US$ as of and for the year ended December 31, 2020 are solely for the convenience of the readers and were calculated at the rate of US$1.00=HK$7.7534, representing the noon buying rate set forth in the H.10 statistical release of the U.S. Federal Reserve Board on December 31, 2020. No representation is made that the HK$ amounts could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2020, or at any other rate.

Current Expected Credit Losses

Prior to January 1, 2020, the Group applied incurred loss methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred.

On January 1, 2020, the Group adopted FASB ASC Topic 326 – “Financial Instruments – Credit Losses” (“ASC Topic 326”) which replaces the incurred loss methodology with the current expected credit loss (“CECL”) methodology. The new guidance applies to financial assets measured at amortized cost, held-to-maturity debt securities and off-balance sheet credit exposures. For on-balance sheet assets, an allowance must be recognized at the origination or purchase of in-scope assets and represents the expected credit losses over the contractual life of those assets.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Current Expected Credit Losses (Continued)

The Group adopted ASC Topic 326 using the modified retrospective approach for all in-scope assets. The adoption of ASC Topic 326 has no impact on the Group’s retained earnings as of January 1, 2020. Results for reporting periods beginning after January 1, 2020 are presented under ASC Topic 326 while prior periods continue to be reported in accordance with previously applicable U.S. GAAP. The Group's in-scope assets are primarily loans and advances that are collateralized by client securities and the collateral is required to be maintained at specified minimum levels at all times. The Group monitors margin levels and requires clients to provide additional collateral, or reduce margin positions, to meet minimum collateral requirements if the fair value of the collateral changes. The Group applies the practical expedient based on collateral maintenance provisions in estimating an allowance for credit losses for the loans and advances. In accordance with the practical expedient, when the Group reasonably expects that borrowers (or counterparties, as applicable) will replenish the collateral as required, there is no expectation of credit losses when the collateral’s fair value is greater than the amortized cost of the financial asset. If the amortized cost exceeds the fair value of collateral, then credit losses are estimated only on the unsecured portion. For the year ended December 31, 2020, expected credit loss expenses of HK$9,075 thousand resulting from the assessment of credit losses for the loans and advances under ASC Topic 326 at period-end is recognized in "Others, net" in the consolidated statements of comprehensive income.

An allowance for credit losses on other financial assets, including receivables from clients, brokers, clearing organization and fund management companies and fund distributors, is estimated based on the aging of these financial receivables. Since most of the financial receivables are short-term in nature, the allowance for credit losses for other financial assets were immaterial for all periods presented.

Cash and Cash Equivalents

Cash and cash equivalents represent cash on hand, demand deposits and time deposits placed with banks or other financial institutions, which are unrestricted to withdrawal or use, and which have original maturities of three months or less.

Cash Held on Behalf of Clients

The Group has classified the clients’ monies as cash held on behalf of clients under the assets section in the consolidated balance sheets and recognized the corresponding accounts payables to the respective clients under the liabilities section.

Term Deposits

Term deposits consist of bank deposits with an original maturity of greater than three months.

Available-for-Sale Financial Securities

Available-for-sale financial securities include debt securities and are measured at fair value. Investments classified as available-for-sale debt securities are reported at fair value with unrealized gains or losses, if any, recorded in accumulated other comprehensive income in the consolidated statements of changes in shareholders’ equity. Debt securities in this category are wealth management products with expected return rate or variable interest rate indexed to investment horizon. These wealth management products are issued by a commercial bank in China and the Group can redeem the units held upon request.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Available-for-Sale Financial Securities (Continued)

Available-for-sale debt securities are impaired if their fair value is below their amortized cost basis. Impairment shall be assessed at the individual security level. An entity shall not combine separate contracts for purposes of determining whether an available-for-sale debt security is impaired or can contractually be prepaid or otherwise settled in such a way that the entity would not recover substantially all of its cost. The Group analyzes the impairment of its available-for-sale debt securities by considering factors including, but not limited to, its ability and intent to hold the individual security, and whether a decline in fair value of the Group’s available-for-sale debt securities is due to any credit related factors. If the Group determines that an impairment of an available-for-sale debt security is due to any credit related factors, losses related to a credit impairment will be recorded as an allowance for credit losses with an offsetting entry to net income, and the portion of losses related to a non-credit factors will be recorded in OCI. If the Group determines that an impairment of the available-for-sale debt security is not related to any credit related factors, no allowance or credit loss expense is recorded, and the non-credit impairment loss will be recorded in OCI. As of December 31, 2019 and 2020, the fair value of the Group’s available-for-sale debt securities is equal to their amortized cost amounting to HK$93,773 thousand and nil, respectively, the Group did not identify any sign for its available-for-sale debt securities to impair.

Equity method investment

In accordance with ASC 323 Investment—Equity Method and Joint Ventures, the Company accounts for an equity method investment over which it has significant influence but does not own a majority of the equity interest or otherwise controls and the investments are either common stock or in substance common stock using the equity method. The Company’s share of the investee’s profit and loss is recognized in the consolidated statements of comprehensive income of the period.

The carrying amount of equity method investment is tested for impairment whenever there is an indication that the carrying amount may be impaired in accordance with the policy described in “Impairment of long-lived assets”.

In January 2019, the Company invested in Zhixiang Technology (Shenzhen) Co., Ltd, a professional stock incentive plan service company. The Company acquired 20% ordinary equity interest with a total consideration of HK$6,709 thousand. The Company exercises significant influence in Zhixiang Technology (Shenzhen) Co., Ltd and therefore accounts for this as an equity method investment. Based on the Group’s assessment on the recoverable amounts of the equity method investment, full impairment provision of HK$5,888 thousand on the equity method investment was made as of December 31, 2020.

Loans and advances

Loans and advances include margin loans, IPO loans extended to clients and other advances, collateralized by securities and are carried at the amortized cost, net of an allowance for doubtful accounts. Revenues earned from the loans and advances are included in interest income.

Margin loans are extended to clients on a demand basis and are not committed facilities. Securities owned by the customers, which are not recorded in the consolidated balance sheets, are held as collateral for amounts due on the margin loans.The outstanding margin loan balances net of allowance as of December 31, 2019 and 2020 were HK$4,141,962 thousand and HK$18,424,972 thousand, respectively.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Loans and advances (Continued)

IPO loans for subscription of new shares are normally settled within one week from the drawdown date. Once IPO stocks are allotted, Futu Securities requires clients to repay the IPO loans. Force liquidation action would be taken if the clients fail to settle their shortfall after the IPO allotment result is announced. The outstanding IPO loan balances as of December 31, 2019 and 2020 were nil and HK$400,394 thousand, respectively.

Other advances consist of bridge loans to enterprises which pledged unlisted or listed shares they hold as collateral.

Loans and advances are initially recorded net of directly attributable transaction costs and are measured at subsequent reporting dates at amortized cost. Finance charges, premiums payable on settlement or redemption and direct costs are accounted for on an accrual basis to the surplus or deficit using the effective interest method and are added to the carrying amount of the instrument to the extent that they are not settled in the period in which they arise.

Trading Receivables from and Payables to Clients

Trading receivables from and payables to clients include amounts due on brokerage transactions on a trade-date basis.

Receivables from and Payables to Brokers, Clearing Organization and Fund Management Companies and Fund Distributors

Receivables from and payables to brokers, clearing organization and fund management companies and fund distributors include receivables and payables from unsettled trades on a trade-date basis, including amounts receivable for securities, derivatives or funds trades not delivered by Futu Securities to the purchaser by the settlement date and cash deposits, and amounts payable for securities, derivatives or funds trades not received by Futu Securities from a seller by the settlement date.

Clearing settlement fund deposited in the clearing organization for the clearing purpose is recognized in receivables from clearing organization.

Futu Securities borrowed margin loans from executing brokers in the United States, with the benchmark interest rate plus premium differentiated depending on the amount borrowed, and immediately lent to margin financing clients. Margin loans borrowed is recognized in the payables to brokers.

Receivables from and payables to fund management companies and fund distributors are currently presented as separate line items on the face of the balance sheet as the management believes that the fund distribution services has become one of the Company’s major businesses. Comparatives have also been reclassified from other assets and accrued expenses and other liabilities for comparability.

The Group's policy is to net the receivables from and payables to clearing organization that meet the offsetting requirements prescribed in ASC Topic 210-20.

Interest Receivable and Payable

Interest receivable is calculated based on the contractual interest rate of bank deposit, loans and advances, securities borrowed and receivables on an accrual basis, and is recorded as interest income as earned.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Interest Receivable and Payable (Continued)

Interest payable is calculated based on the contractual interest rates of payables, borrowings, securities loaned and securities sold under agreements to repurchase on an accrual basis.

Securities Borrowed and Securities Loaned

Securities borrowed and securities loaned are recorded at the amount of the cash collateral advanced or received. Securities borrowed transactions require Futu Securities to provide counterparties with collateral, which may be in the form of cash, or other securities. With respect to securities loaned, Futu Securities receives collateral, which may be in the form of cash or other securities in an amount generally in excess of the fair value of the securities loaned. Futu Securities monitors the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as permitted contractually.

Receivables and payables related to securities borrowed and securities loaned are included at receivables from and payables to brokers or clients in the consolidated balance sheets. Securities lending fees received and securities borrowing fees paid by Futu Securities are included in interest income and interest expense, respectively, in the consolidated statements of comprehensive income.

Securities Sold Under Agreements to Repurchase

Transactions involving sales of securities under agreements to repurchase (repurchase agreements) are treated as collateralized financing transactions. Under repurchase agreements, Futu Securities receives cash from counterparties and provides securities as collateral. These agreements are carried at amounts at which the securities will subsequently be repurchased, and the interest expense incurred by Futu Securities is recorded as interest expenses on the consolidated statements of comprehensive income. As of December 31, 2019 and 2020, the carrying amount of the Group sold securities to other brokers under agreements to repurchase were 1,590 thousand and 5,453,037 thousand, respectively.

Leases

On January 1, 2019, the Group adopted FASB ASC Topic 842, “Leases,” (“ASC Topic 842”) which requires that a lessee recognize in the consolidated balance sheet a lease liability and a corresponding right-of-use asset, including for those leases that the Group currently classifies as operating leases. The right-of-use asset and the lease liability was initially measured using the present value of the remaining lease payments. ASC Topic 842 was implemented using a modified retrospective approach which resulted in no cumulative-effect adjustment in the opening balance of retained earnings as of January 1, 2019. As a result, the consolidated balance sheet prior to January 1, 2019 was not restated and continues to be reported under FASB ASC Topic 840, “Leases,” (“ASC Topic 840”), which did not require the recognition of a right-of-use asset or lease liability for operating leases.

The Group reviews all relevant contracts to determine if the contract contains a lease at its inception date. A contract contains a lease if the contract conveys to the Group the right to control the use of an underlying asset for a period of time in exchange for consideration. If the Group determines that a contract contains a lease, it recognizes, in the consolidated balance sheets, a lease liability and a corresponding right-of-use asset on the commencement date of the lease. The lease liability is initially measured at the present value of the future lease payments over the lease term using the rate implicit in the lease or, if not readily determinable, the Group’s secured incremental borrowing rate. An operating lease right-of-use asset is initially measured at the value of the lease liability minus any lease incentives and initial direct costs incurred plus any prepaid rent.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Leases (Continued)

Each lease liability is measured using the Group’s secured incremental borrowing rate, which is based on an internally developed yield curve using interest rates of debt issued with a similar risk profile as the Group and a duration similar to the lease term. The Group’s leases have remaining terms of one to five years, and some of which include options to terminate the lease upon notice. The Group considers these options when determining the lease term used to calculate the right-of-use asset and the lease liability when the Group is reasonably certain it will exercise such option.

The Group’s operating leases contain both lease components and non-lease components. Non-lease components are distinct elements of a contract that are not related to securing the use of the underlying assets, such as common area maintenance and other management costs. The Company elected to measure the lease liability by combining the lease and non-lease components as a single lease component. As such, the Company includes the fixed payments and any payments that depend on a rate or index that relate to the lease and non-lease components in the measurement of the lease liability. Some of the non-lease components are variable in nature and not based on an index or rate, and as a result, are not included in the measurement of the operating lease right-of-use assets or operating lease liability.

Operating lease expense is recognized on a straight-line basis over the lease term and is included in rental and other related expenses in the Group’s consolidated statements of comprehensive income.

All of the Group’s leases are classified as operating leases and primarily consist of real estate leases for corporate offices, data centers, and other facilities. As of December 31, 2019 and 2020, the weighted-average remaining lease term on these leases is approximately four years and four years, respectively, and the weighted-average discount rate used to measure the lease liabilities was approximately 4.75% and 4.75%, respectively. For the year ended December 31, 2019 and 2020, right-of-use assets obtained under operating leases was HK$211,170 thousand and HK$85,827 thousand, respectively. The Group’s lease agreements do not contain any residual value guarantees, restrictions or covenants.

Refundable Deposit

Refundable deposit is included in other assets in the consolidated balance sheets. As a clearing member firm of Hong Kong Exchanges and Clearing Limited (“HKEx”), the Group is also exposed to clearing member credit risk. HKEx requires member firms to deposit cash to a clearing fund. If a clearing member defaults in its obligations to the clearing organization in an amount larger than its own margin and clearing fund deposits, the shortfall is absorbed pro rata from the deposits of the other clearing members. HKEx has the authority to assess their members for additional funds if the clearing fund is depleted. A large clearing member default could result in a substantial cost if the Group is required to pay such additional funds.

Property and Equipment, net

Property and equipment, which are included in other assets in the consolidated balance sheets are stated at historical cost less accumulated depreciation and impairment, if any. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. Residual rate is determined based on the economic value of the property and equipment at the end of the estimated useful lives as a percentage of the original cost.


Category	Estimated useful lives	Residual rate
Computers equipment	3 - 5 years	5	%
Furniture and fixtures	3 - 5 years	5	%
Office equipment	3 - 5 years	5	%
Vehicle	5 years	5	%
Office building	30 years	5	%

Expenditures for maintenance and repairs are expensed as incurred.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Intangible Assets

Intangible assets which are included in other assets in the consolidated balance sheets mainly consist of computer software and golf membership. Identifiable intangible assets are carried at acquisition cost less accumulated amortization and impairment loss, if any. Finite-lived intangible assets are tested for impairment if impairment indicators arise. Amortization of finite-lived intangible assets is computed using the straight-line method over their estimated useful lives, which are as follows:


Category		Estimated useful lives
Computer software		5 years
Golf membership		10 years

Infinite-lived intangible assets mainly consist of the trading right and license. Futu Securities had held a futures trading right as a clearing member firm of HKEx in order to trade futures through the trading facilities of the Stock Exchange, and has recognized it as intangible assets. Futu Securities obtained an insurance broker license through acquiring a member of the Hong Kong Professional Insurance Brokers Association. The future trading right and insurance broker license have an indefinite useful life and are carried at cost less accumulated impairment losses. The Group will not amortize the future trading right and insurance broker license until its useful life is determined to be finite.

Impairment of Long-lived Assets

Long-lived assets are evaluated for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount may not be fully recoverable or that the useful life is shorter than the Group had originally estimated. When these events occur, the Group evaluates the impairment by comparing carrying value of the assets to an estimate of future undiscounted cash flows expected to be generated from the use of the assets and their eventual disposition. If the sum of the expected future undiscounted cash flows is less than the carrying value of the assets, the Group recognizes an impairment loss based on the excess of the carrying value of the assets over the fair value of the assets. Impairment charge recognized for the years ended December 31, 2018, 2019 and 2020 was nil, nil and HK$ 5,888 thousand, respectively.

Fair Value Measurements

Accounting guidance defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability.

Accounting guidance establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Accounting guidance establishes three levels of inputs that may be used to measure fair value:

Level 1 — Valuation techniques in which all significant inputs are unadjusted quoted prices from active markets for assets or liabilities that are identical to the assets or liabilities being measured.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Fair Value Measurements (Continued)

Level 2 — Valuation techniques in which significant inputs include quoted prices from active markets for assets or liabilities that are similar to the assets or liabilities being measured and/or quoted prices for assets or liabilities that are identical or similar to the assets or liabilities being measured from markets that are not active. Also, model-derived valuations in which all significant inputs and significant value drivers are observable in active markets are Level 2 valuation techniques.

Level 3 — Valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are valuation technique inputs that reflect the Group’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group will measure fair value using valuation techniques that use, when possible, current market-based or independently sourced market parameters, such as interest rates and currency rates.

The carrying amount of cash and cash equivalents, cash held on behalf of clients, receivables from and payables to clients, brokers, clearing organization and fund management companies and fund distributors, accrued interest receivable, accrued interest payable, amounts due to related parties, other financial assets and liabilities approximates fair value because of their short-term nature. Term deposits, loans and advances, borrowings, securities sold under agreements to repurchase and operating lease liabilities are carried at amortized cost. The carrying amount of term deposits, loans and advances, borrowings and operating lease liabilities approximate their respective fair value as the interest rates applied reflect the current quoted market yield for comparable financial instruments. Available-for-sale financial securities are measured at fair value.

The Group’s non-financial assets, such as operating lease right-of-use assets, equity method investment, property and equipment and intangible assets, would be measured at fair value only if they were determined to be impaired.

Revenue Recognition

1)	Brokerage commission and handling charge income

Brokerage commission income earned for executing and/or clearing transactions are accrued on a trade-date basis.

Handling charge income arise from the services such as settlement services, subscription and dividend collection handling services, etc., are accrued on a trade-date basis.

2)	Interest Income

The Group earns interest income primarily in connection with its margin financing and securities lending services, IPO financing, bridge loan and deposits with banks, which are recorded on an accrual basis and are included in interest income in the consolidated statements of comprehensive income. Interest income is recognized as it is accrued using the effective interest method.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Revenue Recognition (Continued)

3)	Other income

Other income consists of enterprise public relations service charge income provided to corporate clients, underwriting fee income, IPO subscription service charge income, currency exchange service income from clients, income from market data service and funds distribution service income from fund management companies, employee share option plan (“ESOP”) management service income, etc.

Enterprise public relations service charge income is charged to corporate clients by providing platform to post their detailed stock information and latest news in Futubull app, as well as providing a lively, interactive community among their potential investors to exchange investment views, share trading experience and socialize with each other. Unearned enterprise public relations service income of which the Group had received the consideration is recorded as contract liabilities (deferred revenue).

IPO subscription service charge income is derived from provision of new share subscription services in relation to IPOs in the Hong Kong capital market.

Underwriting fee income is generated from investment banking business primarily by providing equity sub-underwriting to corporate issuers.

Funds distribution service income is charged to fund management companies for providing fund products distribution service to Futu's individual clients. Futu Securities, as an intermediary would receive subscription fees from fund management companies as agreed in the service contracts.

Market information and data income is charged to Futubull app users for market data service.

Customer loyalty program (Continued)

For the incentives generated from current sales transaction, the Group defers a portion of commission income with corresponding liability reflected as contract liability attributable to the incentives. The contract liability is determined by management based on the expected usage of the incentive points and coupons, and their estimated relative standalone selling price. Significant judgment was made by management in determining the expected usage and estimated relative standalone selling price of the incentive points and coupons, derived from historical trading volume, commission rates and redemption patterns, and an evaluation as to whether historical activities are representative of the expected future activities.

For the incentives offered for future sales transaction, the Group nets a portion of brokerage commission income attributable to the incentives when points or coupons are actually redeemed.

For the incentives that are considered to be a payment of other distinct goods, the incentives are accounted for as selling and marketing expense with corresponding liability reflected as other liability on the consolidated balance sheet.

The table below presents the deferred or netted brokerage commission income related to the customer loyalty program for the years ended December 31, 2018, 2019 and 2020.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Share-Based Compensation

The Company follows ASC 718 to determine whether a share option and a restricted share units should be classified and accounted for as a liability award or equity award. All share-based awards to employees and directors classified as equity awards , such as stock options and restricted share units, are measured at the grant date based on the fair value of the awards. Share-based compensation, net of estimated forfeitures, is recognized as expenses on a straight-line method over the requisite service period, which is the vesting period. Options granted generally vest over four or five years.

The modification of the terms or conditions of the existing shared-based award is treated as an exchange of the original award for a new award. The incremental compensation expenses are equal to the excess of the fair value of the modified award immediately after the modification over the fair value of the original award immediately before the modification. For stock options already vested as of the modification date, the Group immediately recognized the incremental value as compensation expenses. For stock options still unvested as of the modification date, the incremental compensation expenses are recognized over the remaining service period of these stock options.

The Company determined the fair value of the restricted share units with reference to the fair value of the underlying shares as of the grant date. The Company utilizes the binomial option pricing model to estimate the fair value of stock options granted, with the assistance of an independent valuation firm.

Forfeitures are estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates. The Group uses historical data to estimate pre-vesting options and records share-based compensation expenses only for those awards that are expected to vest. See Note 15 for further discussion on share-based compensation.

Taxation

1)	Income tax

Current income taxes are provided on the basis of net income for financial reporting purposes, adjusted for income and expense items which are not assessable or deductible for income tax purposes, in accordance with the regulations of the relevant tax jurisdictions. Deferred income taxes are accounted for using an asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax base of an asset or liability is the amount attributed to that asset or liability for tax purpose. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of comprehensive income in the period of change. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered more likely than not that some portion of, or all of the deferred tax assets will not be realized.

2)	Uncertain tax positions

The Group did not recognize any interest and penalties associated with uncertain tax positions for the years ended December 31, 2018, 2019 and 2020. As of December 31, 2019 and 2020, the Group did not have any significant unrecognized uncertain tax positions.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Net income per share

Basic net income per share is computed by dividing net income attributable to ordinary shareholder, considering the accretion of redemption feature and cumulative dividend related to the Company’s redeemable convertible preferred shares, and undistributed earnings allocated to redeemable convertible preferred shares by the weighted average number of ordinary shares outstanding during the period using the two-class method. Under the two-class method, net income is allocated between ordinary shares and other participating securities based on their participating rights. Net loss is not allocated to other participating securities if based on their contractual terms they are not obligated to share the losses.

Diluted net income per share is calculated by dividing net income attributable to ordinary shareholder, as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the period. Ordinary equivalent shares consist of ordinary shares issuable upon the conversion of the redeemable convertible preferred shares, using the if-converted method, and shares issuable upon the exercise of share options using the treasury stock method. Ordinary equivalent shares are not included in the denominator of the diluted net income per share calculation when inclusion of such share would be anti-dilutive.

Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-makers has been identified as the Chief Executive Officer who allocates resources to and assesses the performance of the operating segments of an entity. The Group’s reporting segments are decided based on its operating segments while taking full consideration of various factors such as products and services, geographic location and regulatory environment related to administration of the management. Operating segments meeting the same qualifications are allocated as one reporting segment, providing independent disclosures.

The Group engages primarily in online brokerage services and margin financing services. The Group does not distinguish between markets or segments for the purpose of internal reports. The Group does not distinguish revenues, costs and expenses between segments in its internal reporting, and reports costs and expenses by nature as a whole. Hence, the Group has only one reportable segment.

Significant Risks and Uncertainties

1)	Currency risk

Currency risk arises from the possibility that fluctuations in foreign exchange rates will impact the financial instruments. Futu Securities is not exposed to significant transactional foreign currency risk since almost all of its transactions, assets and liability are denominated in Hong Kong dollars and U.S. dollars and Hong Kong dollars are pegged against U.S. dollars. The impact of foreign currency fluctuations in the Group’s earnings is included in “Others, net” in the consolidated statements of comprehensive income. At the same time, the Group is exposed to translational foreign currency risk since some of the Company's major subsidiaries have RMB as their functional currency. Therefore, RMB depreciation against Hong Kong dollars could have a material adverse impact on the foreign currency translation adjustment in the consolidated statements of comprehensive income.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Significant Risks and Uncertainties (Continued)

1)	Currency risk (Continued)

As of December 31, 2019 and 2020, the Group had RMB-denominated net liabilities of HK$94.3 million (US$ 12.1 million) and HK$262.9 million (US$33.9 million) respectively. We estimate that a 10% depreciation of Renminbi against the U.S. dollar based on the foreign exchange rate on December 31, 2019 and 2020 would result in an increase of US$1.2 million and US$3.4 million, respectively, in the Group’s pre-tax profit as of December 31, 2019 and 2020, and a 10% appreciation of Renminbi against the U.S. dollar based on the foreign exchange rate on December 31, 2019 and 2020 would result in a decrease of US$1.2 million and US$3.4 million, respectively, in the Group’s pre-tax profit as of December 31, 2019 and 2020.

2)	Credit risk

Cash held on behalf of clients are segregated and deposited in financial institutions as required by the Securities and Futures Ordinance and the Uniform Net Capital Rule (Rule 15c3-1). These financial institutions are of sound credit ratings, therefore management believes that there is no significant credit risk related to cash held on behalf of clients.

The Group’s securities and derivative trades activities are transacted on either a cash or margin basis. The Group's credit risk is limited in that substantially all of the contracts entered into are settled directly at securities and derivatives clearing organization. In margin transactions, the Group extends credit to the client, subject to various regulatory and internal margin requirements, collateralized by cash and securities in the client’s account. IPO loans are exposed to credit risk from clients who fails to repay the loans upon IPO stock allotment. The Group monitors the clients’ collateral level and has the right to dispose the newly allotted stocks once the stocks first start trading. Bridge loans to enterprise pledged by shares are exposed to credit risk from counterparties who fail to repay the loans, the Group monitors on the collateral level of bridge loans in real time, and has the right to dispose of the pledged shares once the collateral level falls under the minimal level required to get the loans repaid.

Liabilities to other brokers and dealers related to unsettled transactions are recorded at the amount for which the securities were purchased, and are paid upon receipt of the securities from other brokers or dealers.

In connection with its clearing activities, the Group is obligated to settle transactions with brokers and other financial institutions even if its clients fail to meet their obligations to the Group. Clients are required to complete their transactions by the settlement date, generally two business days after the trade date. If clients do not fulfill their contractual obligations, the Group may incur losses. The Group has established procedures to reduce this risk by generally requiring that clients deposit sufficient cash and/or securities into their account prior to placing an order.

For cash management purposes, the Group enters into short-term securities sold under agreements to repurchase transactions ("repos") in addition to securities borrowing and lending arrangements, all of which may result in credit exposure in the event the counterparty to a transaction is unable to fulfill its contractual obligations. Repos are collateralized by securities with a market value in excess of the obligation under the contract. Similarly, securities lending agreements are collateralized by deposits of cash or securities. The Group attempts to minimize credit risk associated with these activities by monitoring collateral values on a daily basis and requiring additional collateral to be deposited with or returned to the Group as permitted under contractual provisions.

Significant Risks and Uncertainties (Continued)

2)	Credit risk (Continued)

Concentrations of Credit Risk

The Group’s exposure to credit risk associated with its brokerage and other activities is measured on an individual counterparty basis, as well as by groups of counterparties that share similar attributes. There was no revenue from clients which individually represented greater than 10% of the total revenues for the years ended December 31, 2018, 2019 and 2020, respectively. Concentrations of credit risk can be affected by changes in political, industry, or economic factors. To reduce the potential for risk concentration, credit limits are established and exposure is monitored in light of changing counterparty and market conditions. As of December 31, 2019 and 2020, the Group did not have any material concentrations of credit risk within or outside the ordinary course of business.

3)	Interest rate risk

Fluctuations in market interest rates may negatively affect the Group’s financial condition and results of operations. The Group are exposed to floating interest rate risk on cash deposit and floating rate borrowings. We use net interest simulation modeling techniques to evaluate the effect that changes in interest rates might have on net income. The model includes all interest-sensitive assets and liabilities. The simulations involve assumptions that are inherently uncertain and, as a result, cannot precisely predict the impact that changes in interest rates will have on net income. Actual results may differ from simulated results due to differences in timing and frequency of rate changes, changes in market conditions and changes in management strategy that lead to changes in the mix of interest-sensitive assets and liabilities.

The simulations assume that the asset and liability structure of the consolidated balance sheets would not be changed as a result of a simulated change in interest rates. The results of the simulations based on the Group’s financial position as of December 31, 2020 indicate that a gradual 1% (100 basis points) increase in interest rates over a 12-month period would result in approximately HK$65.4 million (US$8.4 million) net income and a gradual 1% (100 basis points) decrease in interest rates over a 12-month period would result in approximately HK$65.4 million (US$8.4 million) net loss, depending largely on the extent and timing of possible changes in floating rates.

Recent Accounting Pronouncements

In June 2016, the FASB amended guidance related to impairment of financial instruments as part of ASU 2016-13 Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which is effective on January 1, 2020. The guidance replaces the incurred loss impairment methodology with an expected credit loss model for which the group is required to recognize an allowance based on its estimate of expected credit loss. In November 2018, FASB issued ASU No, 2018-19, Codification Improvements to Topic 326, further clarified the scope of the guidance in the amendments in ASU 2016-13. In May 2019, FASB issued ASU No.2019-05, Financial instrument—Credit Losses(Topic 326), Targeted Transition Relief, which provides an irrevocably fair value option to elect for eligible instruments. In November 2019, FASB issued ASU 2019-11 Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which clarified and improved various aspects of ASU 2016-13. In March 2020, FASB issued ASU 2020-03, Codification Improvements to Financial Instruments, which improves and clarifies various financial instruments topics, including the current expected credit losses standard. As of January 1, 2020, the Group adopted ASC Topic 326 using the modified retrospective approach for all in-scope assets. The adoption of ASC Topic 326 has no impact on the Group's retained earnings as of January 1, 2020. Results for reporting periods beginning after January 1, 2020 are presented under ASC Topic 326 while prior periods continue to be reported in accordance with previously applicable U.S. GAAP.

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this standard will remove, modify and add certain disclosures under ASC Topic 820, Fair Value Measurement, with the objective of improving disclosure effectiveness. ASU 2018-13 is effective for the Group’s fiscal year beginning January 1, 2020, with early adoption permitted. The update eliminates the requirement to disclose: (a) the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (b) an entity's policy for timing of transfers between levels; (c) and an entity's valuation processes for Level 3 fair value measurements. The Group adopted ASU 2018-13 on January 1, 2020, and the adoption had no material impact on the Group’s consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income taxes (Topic 740)-Simplifying the accounting for income taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, Income Taxes. The ASU will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Group is currently evaluating the impact of this new guidance on the consolidated financial statements but does not expect this guidance will have a material impact on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting if certain criteria are met. The amendments in ASU 2020-04 provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This guidance is effective immediately and the amendments may be applied prospectively through December 31, 2022. The adoption did not have a material accounting impact on the Group's consolidated financial position or results of operations.
