The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP"). The preparation of the consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

The consolidated financial statements include AB and its majority-owned and/or controlled subsidiaries, and the consolidated entities that are considered to be variable interest entities ("VIEs") and voting interest entities ("VOEs") in which AB has a controlling financial interest. Non-controlling interests on the consolidated statements of financial condition include the portion of consolidated company-sponsored investment funds in which we do not have direct equity ownership. All significant inter-company transactions and balances among the consolidated entities have been eliminated.

In August 2018, the Financial Accounting Standards Board (the "FASB") issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Topic 715-20). The amendment modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans. We adopted this standard prospectively on January 1, 2021. The adoption of this standard did not have a material impact on our financial condition or results of operations.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify US GAAP for other areas of Topic 740 by clarifying and amending the existing guidance. We adopted this standard prospectively on January 1, 2021. The adoption of this standard did not have a material impact on our financial condition or results of operations.

AB provides asset management services by managing customer assets and seeking to deliver investment returns to investors. Each investment management contract between AB and a customer creates a distinct, separately identifiable performance obligation for each day the customer’s assets are managed as the customer can benefit from each day of service. In accordance with ASC 606, a series of distinct goods and services that are substantially the same and have the same pattern of transfer to the customer are treated as a single performance obligation. Accordingly, we have determined that our investment and advisory services are performed over time and entitle us to variable consideration earned based on the value of the investors’ assets under management (“AUM”).

We calculate AUM using established market-based valuation methods and fair valuation (non-observable market) methods. Market-based valuation methods include: last sale/settle prices from an exchange for actively-traded listed equities, options and futures; evaluated bid prices from recognized pricing vendors for fixed income, asset-backed or mortgage-backed issues; mid prices from recognized pricing vendors and brokers for credit default swaps; and quoted bids or spreads from pricing vendors and brokers for other derivative products. Fair valuation methods include: discounted cash flow models or any other methodology that is validated and approved by our Valuation Committee (see paragraph immediately below for additional information about our Valuation Committee). Fair valuation methods are used only where AUM cannot be valued using market-based valuation methods, such as in the case of private equity or illiquid securities.

The Valuation Committee, which consists of senior officers and employees, is responsible for overseeing the pricing and valuation of all investments held in client and AB portfolios. The Valuation Committee has adopted a Statement of Pricing Policies describing principles and policies that apply to pricing and valuing investments held in these portfolios. We also have a Pricing Group, which reports to the Valuation Committee and is responsible for overseeing the pricing process for all investments.

We record as revenue investment advisory and services base fees, which we generally calculate as a percentage of AUM. At month-end, all the components of the transaction price (i.e., the base fee calculation) are no longer variable and the value of the consideration is determined. These fees are not subject to claw back and there is minimal probability that a significant reversal of the revenue recorded will occur.

The transaction price for the asset management performance obligation for certain investment advisory contracts, including those associated with hedge funds or other alternative investments, provide for a performance-based fee (including carried interest), in addition to a base advisory fee, which is calculated as either a percentage of absolute investment results or a percentage of investment results in excess of a stated benchmark over a specified period of time. The performance-based fees are forms of variable consideration and are therefore excluded from the transaction price until it becomes probable that there will not be significant reversal of the cumulative revenue recognized. At each reporting date, we evaluate the constraining factors, discussed below, surrounding the variable consideration to determine the extent to which, if any, revenues associated with the performance-based fee can be recognized.

Constraining factors impacting the amount of variable consideration included in the transaction price include: the contractual claw-back provisions to which the variable consideration is subject, the length of time to which the uncertainty of the consideration is subject, the number and range of possible consideration amounts, the probability of significant fluctuations in the fund’s market value, the level at which the fund’s value exceeds the contractual threshold required to earn such a fee, and the materiality of the amount being evaluated.

Bernstein Research Services revenue consists principally of commissions received, and to a lesser but increasing extent, direct payments for trade execution services and equity research services provided to institutional clients. Brokerage commissions for trade execution services and related expenses are recorded on a trade-date basis when the performance obligations are satisfied. Generally, the transaction price is agreed upon at the time of each trade and is based upon the number of shares traded or the value of the consideration traded. Research revenues are recognized when the transaction price is quantified, collectability is assured and significant reversal of such revenue is not probable.

Two of our subsidiaries act as distributors and/or placement agents of company-sponsored mutual funds and receive distribution services fees from certain of those funds as full or partial reimbursement of the distribution expenses they incur. The variable consideration can be determined in different ways, as discussed below, as we satisfy the performance obligation depending on the contractual arrangements with the customer and the specific product sold.

Most open-end U.S. funds have adopted a plan under Rule 12b-1 of the Investment Company Act that allows the fund to pay, out of assets of the fund, distribution and service fees for the distribution and sale of its shares (“12b-1 fees”). The open-end U.S. funds have such agreements with us, and we have selling and distribution agreements pursuant to which we pay sales commissions to the financial intermediaries that distribute our open-end U.S. funds. These agreements are terminable by either party upon notice (generally 30 days) and do not obligate the financial intermediary to sell any specific amount of fund shares.

We record 12b-1 fees monthly based upon a percentage of the net asset value (“NAV”) of the funds. At month-end, the variable consideration of the transaction price is no longer constrained as the NAV can be calculated and the value of consideration is determined. These services are separate and distinct from other asset management services as the customer can benefit from these services independently of other services. We accrue the corresponding 12b-1 fees paid to sub-distributors monthly as the expenses are incurred. We are acting in a principal capacity in these transactions; as such, these revenues and expenses are recorded on a gross basis.

We offer back-end load shares in limited instances and charge the investor a contingent deferred sales charge (“CDSC”) if the investment is redeemed within a certain period. The variable consideration for these contracts is contingent on the timing of the redemption by the investor and the value of the sale proceeds. Due to these constraining factors, we exclude the CDSC fee from the transaction price until the investor redeems the investment. Upon redemption, the cash consideration received for these contractual arrangements are recorded as reductions of unamortized deferred sales commissions.

Our Luxembourg subsidiary, the management company for most of our non-U.S. funds, earns a management fee that is accrued daily and paid monthly, at an annual rate, based on the average daily net assets of the fund. With respect to certain share classes, the management fee may also contain a component that is paid to distributors and other financial intermediaries and service providers to cover shareholder servicing and other administrative expenses (also referred to as an All-in-Fee). As we have concluded that asset management is distinct from distribution, we allocate a portion of the investment and advisory fee to distribution revenues for the servicing component based on standalone selling prices.

We provide shareholder services, which include transfer agency, administrative and recordkeeping services provided to company-sponsored mutual funds. The consideration for these services is based on a percentage of the NAV of the fund or a fixed-fee based on the number of shareholder accounts being serviced. The revenues are recorded at month-end when the constraining factors involved with determining NAV or the number of shareholders’ accounts are resolved.

Dividend and interest income is accrued as earned. Investment gains and losses on the consolidated statements of income include unrealized gains and losses of trading and private equity investments stated at fair value, equity in earnings of our limited partnership hedge fund investments, and realized gains and losses on investments sold.

We use the practical expedient for contracts that have an original duration of one year or less. Accordingly, we do not consider the time value of money and, instead, accrue the incremental costs of obtaining the contract when incurred. As of December 31, 2021, the balances of contract assets and contract liabilities are not considered material and, accordingly, no further disclosures are necessary.

For legal entities (company-sponsored investment funds) evaluated for consolidation, we first determine whether the fees we receive and the interests we hold qualify as a variable interest in the entity, including an evaluation of fees paid to us as a decision maker or service provider to the entity being evaluated. Fees received by us are not variable interests if (i) the fees are compensation for services provided and are commensurate with the level of effort required to provide those services, (ii) the service arrangement includes only terms, conditions or amounts that are customarily present in arrangements for similar services negotiated at arm’s length, and (iii) our other economic interests in the entity held directly and indirectly through our related parties, as well as economic interests held by related parties under common control, would not absorb more than an insignificant amount of the entity’s losses or receive more than an insignificant amount of the entity’s benefits.

For those entities in which we have a variable interest, we perform an analysis to determine whether the entity is a VIE by considering whether the entity’s equity investment at risk is insufficient, whether the investors lack decision making rights proportional to their ownership percentage of the entity, and whether the investors lack the obligation to absorb an entity’s expected losses or the right to receive an entity’s expected income.

A VIE must be consolidated by its primary beneficiary, which generally is defined as the party that has a controlling financial interest in the VIE. We are deemed to have a controlling financial interest in a VIE if we have (i) the power to direct the activities of the VIE that most significantly affect the VIE's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive income from the VIE that could potentially be significant to the VIE. For purposes of evaluating (ii) above, fees paid to us as a decision maker or service provider are excluded if the amount of fees is commensurate with the level of effort required to be performed and the arrangement includes only customary terms, conditions or amounts present in arrangements for similar services negotiated at arm’s length. The primary beneficiary evaluation generally is performed qualitatively based on all facts and circumstances, as well as quantitatively, as appropriate.

If we have a variable interest in an entity that is determined not to be a VIE, the entity is then evaluated for consolidation under the VOE model. For limited partnerships and similar entities, we are deemed to have a controlling financial interest in a VOE, and would be required to consolidate the entity, if we own a majority of the entity’s kick-out rights through voting limited partnership interests and limited partners do not hold substantive participating rights (or other rights that would indicate that we do not control the entity). For entities other than limited partnerships, we are deemed to have a controlling financial interest in a VOE if we own a majority voting interest in the entity.

Cash and cash equivalents include cash on hand, demand deposits, money market accounts, overnight commercial paper and highly liquid investments with original maturities of three months or less. Due to the short-term nature of these instruments, the recorded value has been determined to approximate fair value (and considered Level 1 securities in the fair value hierarchy).

Fees receivable are shown net of allowances. An allowance for doubtful accounts related to investment advisory and services fees is determined through an analysis of the aging of receivables, assessments of collectability based on historical trends and other qualitative and quantitative factors, including our relationship with the client, the financial health (or ability to pay) of the client, current economic conditions and whether the account is active or closed. The allowance for doubtful accounts is not material to fees receivable.

Customers’ securities transactions are recorded on a settlement date basis, with related commission income and expenses reported on a trade date basis. Receivables from and payables to clients include amounts due on cash and margin transactions. Securities owned by customers are held as collateral for receivables; such collateral is not reflected in the consolidated financial statements. We have the ability by contract or custom to sell or re-pledge this collateral, and have done so at various times. As of December 31, 2021 and 2020, we had $23.4 million and zero of re-pledged securities, respectively. Principal securities transactions and related expenses are recorded on a trade date basis.

Securities borrowed and securities loaned by our broker-dealer subsidiaries are recorded at the amount of cash collateral advanced or received in connection with the transaction and are included in receivables from and payables to brokers and dealers in the consolidated statements of financial condition. Securities borrowed transactions require us to deposit cash collateral with the lender. With respect to securities loaned, we receive cash collateral from the borrower. See Note 8 for securities borrowed and loaned amounts recorded in our consolidated statements of financial condition as of December 31, 2021 and 2020. The initial collateral advanced or received approximates or is greater than the fair value of securities borrowed or loaned. We monitor the fair value of the securities borrowed and loaned on a daily basis and request additional collateral or return excess collateral, as appropriate. As of December 31, 2021 and 2020, there is no allowance provision required for the collateral advanced. Income or expense is recognized over the life of the transaction.

As of December 31, 2021 and 2020, we had $114.9 million and $130.0 million, respectively, of cash on deposit with clearing organizations for trade facilitation purposes, which are reported in other assets in our consolidated statements of financial condition. As of December 31, 2021 and 2020, we held no U.S. Treasury bills pledged as collateral. These clearing organizations have the ability by contract or custom to sell or re-pledge the collateral, if any.

Receivables from clients primarily consists of margin loan balances. The value of the securities owned by clients and held as collateral for these receivables is not reflected in the consolidated financial statements and the collateral was not repledged or sold as of December 31, 2021 and 2020. We consider these financing receivables to be of good credit quality due to the fact that these receivables are primarily collateralized by the related client investments.

To estimate expected credit losses on margin loans, we applied the collateral maintenance practical expedient by comparing the amortized cost basis of the margin loans with the fair value of the collateral at the reporting date. Margin loans are limited to a percentage of the total value of the securities held in the client's account against those loans. AB requires, in the event of a decline in the market value of the securities in a margin account, the client to deposit additional securities or cash so that, at all times, the value of the securities in the account, at a minimum, cover the loan to the client. As such, AB reasonably expects that the borrower will be able to continually replenish collateral securing the financial asset and does not expect the fair value of collateral to fall below the amortized cost basis of the margin loans and, as a result, we consider the credit risk associated with these receivables to be minimal. In circumstances when a loan becomes undercollateralized and the client fails to deposit additional securities or cash, AB reserves the right to liquidate the account.

The majority of our revenue receivables are from investment advisory and service fees, and distribution revenues, that are typically paid out of the client accounts or third-party products consisting of cash and securities. Due to the size of the fees in relation to the value of the cash and securities in account or funds, the account value always exceeds the amortized cost basis of the receivables, resulting in a remote risk of loss. These receivables have a short duration, generally due within 30-90 days and there is minimal historical evidence of non-payment or market declines that would cause the fair value of the underlying securities to decline below the amortized cost of the receivables. AB maintains an allowance for credit losses based upon an estimate of the amount of potential credit losses in existing accounts receivable, as determined from a review of aging schedules, past due balances, historical collection experience and other specific account data. Once determined uncollectible, aged balances are written off as credit loss expense. This determination is based on careful analysis of individual receivables and aging schedules, and generally occurs when the receivable becomes over 360 days past due. Our aged receivables and amounts written off related to credit losses in any year are not material.

Furniture, equipment and leasehold improvements are stated at cost, less accumulated depreciation and amortization. Depreciation is recognized on a straight-line basis over the estimated useful lives of eight years for furniture and three to six years for equipment and software. Leasehold improvements are amortized on a straight-line basis over the lesser of their estimated useful lives or the terms of the related leases.

In 2000, AB acquired SCB Inc., an investment research and management company formerly known as Sanford C. Bernstein Inc. (“Bernstein”). The Bernstein acquisition was accounted for under the purchase method, and the cost of the acquisition was allocated on the basis of the estimated fair value of the assets acquired and the liabilities assumed. The excess of the purchase price over the fair value of identifiable assets acquired, net of liabilities assumed, resulted in the recognition of goodwill of approximately $3.0 billion.

Goodwill is tested annually, as of September 30, for impairment utilizing the market approach where the fair value of the reporting unit is based on its unadjusted market valuation (AB Units outstanding multiplied by AB Holding's Unit price) and adjusted market valuations assuming a control premium (when applicable). The price of a publicly-traded AB Holding Unit serves as a reasonable starting point for valuing an AB Unit because each represents the same fractional interest in our underlying business. Throughout the year, the carrying value of goodwill is also reviewed for impairment if certain events or changes in circumstances occur and trigger whether an interim impairment test may be required. Such changes in circumstances may include, but are not limited to, a sustained decrease in the price of an AB Holding Unit or declines in AB’s market capitalization that would suggest that the fair value of the reporting unit is less than the carrying amount; significant and unanticipated declines in AB’s assets under management or revenues; and/or lower than expected earnings per unit. Any of these changes in circumstances could suggest the possibility that goodwill is impaired, but none of these events or circumstances by itself would indicate that it is more likely than not that goodwill is impaired. Instead, they are merely recognized as triggering events for the consideration of impairment and must be viewed in combination with any mitigating or positive factors. A holistic evaluation of all events since the most recent quantitative impairment test must be done to

Under ASU 2017-04, Simplifying the Test for Goodwill Impairment, a goodwill impairment will be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Under this guidance, the goodwill impairment test no longer includes a determination by management of whether a decline in fair value is temporary; however, it is important that management's determination of fair value reflect the impact of changing market conditions, including the severity and anticipated duration of any such changes.

Intangible assets consist primarily of costs assigned to acquired investment management contracts based on their estimated fair value at the time of acquisition, less accumulated amortization. Intangible assets are recognized at fair value and generally are amortized on a straight-line basis over their estimated useful life ranging from seven to 20 years.

As of December 31, 2021, intangible assets, net of accumulated amortization, of $41.5 million on the consolidated statement of financial condition consists of $26.3 million of finite-lived intangible assets subject to amortization and $15.2 million of indefinite-lived intangible assets not subject to amortization. As of December 31, 2020, intangible assets, net of accumulated amortization, of $44.5 million on the consolidated statement of financial condition consisted of $29.2 million of finite-lived intangible assets subject to amortization and $15.3 million of indefinite-lived intangible assets not subject to amortization in regard to other acquisitions. The gross carrying amount of finite-lived intangible assets totaled $53.8 million as of December 31, 2021 and $65.1 million as of December 31, 2020, and accumulated amortization was $27.5 million as of December 31, 2021 and $35.9 million as of December 31, 2020. Amortization expense was $5.7 million for 2021, $21.4 million for 2020 and $28.8 million for 2019. Estimated annual amortization expense for 2022 is approximately $5 million, $5 million in years two and three, $4 million in year four and then approximately $2 million in year five.

We periodically review indefinite-lived intangible assets for impairment as events or changes in circumstances indicate that the carrying value may not be recoverable. If the carrying value exceeds fair value, we perform additional impairment tests to measure the amount of the impairment loss, if any. During the fourth quarter of 2021 and 2020, we recorded an impairment of $1.0 million and $1.5 million, respectively, relating to our 2016 acquisition of Ramius Alternative Solutions LLC. Due to the loss of acquired investment management contracts during 2021, the carrying value of the finite-lived intangible assets exceeded the fair value of the contracts. We determined the fair value of the contracts using a discounted cash flow model. The impairment charge was recorded in general and administrative expenses in the consolidated statements of income.

We pay commissions to financial intermediaries in connection with the sale of shares of open-end company-sponsored mutual funds sold without a front-end sales charge (“back-end load shares”). These commissions are capitalized as deferred sales commissions and amortized over periods not exceeding one year for U.S. fund shares and four years for Non-U.S. Fund shares, the periods of time during which deferred sales commissions generally are recovered. We recover these commissions from distribution services fees received from those funds and from CDSC received from shareholders of those funds upon the redemption of their shares. CDSC cash recoveries are recorded as reductions of unamortized deferred sales commissions when received. Since January 31, 2009, our U.S. mutual funds have not offered back-end load shares to new investors.

We periodically review the deferred sales commission asset for impairment as events or changes in circumstances indicate that the carrying value may not be recoverable. If these factors indicate impairment in value, we compare the carrying value to the undiscounted cash flows expected to be generated by the asset over its remaining life. If we determine the deferred sales commission asset is not fully recoverable, the asset will be deemed impaired and a loss will be recorded in the amount by which the recorded amount of the asset exceeds its estimated fair value. There were no impairment charges recorded during 2021 or 2020.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use our consolidated incremental borrowing rate based on the information available as of the lease commencement date in determining the present value of lease payments. Our lease terms may include options to extend or terminate the lease. These options to extend or terminate are assessed on a lease-by-lease basis, and the ROU assets and lease liabilities are adjusted when it is reasonably certain that an option will be exercised.

When calculating the measurement of ROU assets and lease liabilities, we utilize the fixed payments associated with the lease and do not include other variable contractual obligations, such as operating expenses, real estate taxes, cleaning and utilities. These costs are accounted for as period costs and expensed as incurred.

With respect to all significant litigation matters, we consider the likelihood of a negative outcome. If we determine the likelihood of a negative outcome is probable and the amount of the loss can be reasonably estimated, we record an estimated loss for the expected outcome of the litigation. If the likelihood of a negative outcome is reasonably possible and we are able to determine an estimate of the possible loss or range of loss in excess of amounts already accrued, if any, we disclose that fact together with the estimate of the possible loss or range of loss. However, it is often difficult to predict the outcome or estimate a possible loss or range of loss because litigation is subject to inherent uncertainties, particularly when plaintiffs allege substantial or indeterminate damages. Such is also the case when the litigation is in its early stages or when the litigation is highly complex or broad in scope. In these cases, we disclose that we are unable to predict the outcome or estimate a possible loss or range of loss.

We periodically enter into contingent payment arrangements in connection with our business combinations. In these arrangements, we agree to pay additional consideration to the sellers to the extent that certain performance targets are achieved. We estimate the fair value of these potential future obligations at the time a business combination is consummated and record a liability on our consolidated statements of financial condition. We then accrete the obligation to its expected payment amount over the measurement period. If our expected payment amount subsequently changes, the obligation is modified in the current period resulting in a gain or loss. Both gains and losses resulting from changes to expected payments and the accretion of these obligations to their expected payment amounts are reflected within contingent payment arrangements in our consolidated statements of income. During the fourth quarters of 2021 and 2020, we recorded an impairment of the contingent consideration payable of $0.6 million and $1.4 million, respectively. This impairment was related to our 2016 acquisition of Ramius Alternative Solutions LLC.

Purchases and sales of shares of company-sponsored mutual funds in connection with the underwriting activities of our subsidiaries, including related commission income, are recorded on the trade date. Receivables from brokers and dealers for sale of shares of company-sponsored mutual funds generally are realized within three business days from the trade date, in conjunction with the settlement of the related payables to company-sponsored mutual funds for share purchases. Distribution plan and other promotion and servicing payments are recognized as expense when incurred.

We maintain several unfunded, non-qualified long-term incentive compensation plans, under which we grant annual awards to employees, generally in the fourth quarter, and to members of the Board of Directors of the General Partner, who are not employed by our company or by any of our affiliates ("Eligible Directors").

Awards granted in December 2021, 2020 and 2019 allowed employee participants to allocate their awards between restricted AB Holding Units and deferred cash. Participants (except certain members of senior management) generally could allocate up to 50% of their awards to deferred cash, not to exceed a total of $250,000 per award. Each of our employees based outside of the United States (other than expatriates), who received an award of $100,000 or less, could have allocated 100% of his or her award to deferred cash. Participants allocated their awards prior to the date on which the Compensation and Workplace Practices Committee (the "Compensation Committee") of the Board of Directors (the "Board") approved awards in December 2021, 2020 and 2019. For these awards, the number of AB Holding Units awarded was based on the closing price of an AB Holding Unit on the grant date. For awards granted in 2021, 2020 and 2019:

We recognize compensation expense related to equity compensation grants in the financial statements using the fair value method. Fair value of restricted AB Holding Unit awards is the closing price of an AB Holding Unit on the grant date; fair value of options is determined using the Black-Scholes option valuation model. Under the fair value method, compensatory expense is measured at the grant date based on the estimated fair value of the award and is recognized over the required service period. For year-end long-term incentive compensation awards, employees who resign or are terminated without cause may retain their awards, subject to compliance with certain agreements and restrictive covenants set forth in the applicable award agreement, including restrictions on competition and employee and client solicitation, and a claw-back for failing to follow existing risk management policies. Because there is no service requirement, we fully expense these awards on the grant date. Most equity replacement, sign-on or similar deferred compensation awards included in separate employment agreements or arrangements include a required service period. Regardless of whether or not the award agreement includes employee service requirements, AB Holding Units typically are delivered to employees ratably over three years to four years, unless the employee has made a long-term deferral election.

Grants of restricted AB Holding Units can be awarded to Eligible Directors. Generally, these restricted AB Holding Units vest ratably over four years. These restricted AB Holding Units are not forfeitable (except if the Eligible Director is terminated for “Cause,” as that term is defined in the applicable award agreement). We fully expense these awards on grant date, as there is no service requirement.

We fund our restricted AB Holding Unit awards either by purchasing AB Holding Units on the open market or purchasing newly-issued AB Holding Units from AB Holding, and then keeping these AB Holding Units in a consolidated rabbi trust until delivering them or retiring them. In accordance with the Amended and Restated Agreement of Limited Partnership of AB (“AB Partnership Agreement”), when AB purchases newly-issued AB Holding Units from AB Holding, AB Holding is required to use the proceeds it receives from AB to purchase the equivalent number of newly-issued AB Units, thus increasing its percentage ownership interest in AB. AB Holding Units held in the consolidated rabbi trust are corporate assets in the name of the trust and are available to the general creditors of AB.

Each quarter, we consider whether to implement a plan to repurchase AB Holding Units pursuant to Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended (“Exchange Act”). A plan of this type allows a company to repurchase its shares at times when it otherwise might be prevented from doing so because of self-imposed trading blackout periods or because it possesses material non-public information. Each broker we select has the authority to repurchase AB Holding Units on our behalf in accordance with the terms and limitations specified in the plan. Repurchases are subject to regulations promulgated by the SEC as well as certain price, market volume and timing constraints specified in the plan. There was no plan adopted during the fourth quarter of 2021. We may adopt additional plans in the future to engage in open-market purchases of AB Holding Units to help fund anticipated obligations under our incentive compensation award program and for other corporate purposes.

During 2021, we granted to employees and Eligible Directors 7.0 million restricted AB Holding Units (including 3.4 million granted in December for 2021 year-end awards to employees). During 2020, we granted to employees and Eligible Directors 5.7 million restricted AB Holding Units (including 5.0 million granted in December for 2020 year-end awards to employees). We used AB Holding Units repurchased during the periods and newly-issued AB Holding Units to fund these awards.

During 2021 and 2020, AB Holding issued 0.1 million and 5,182 AB Holding Units, respectively, upon exercise of options to buy AB Holding Units. AB Holding used the proceeds of $3.4 million and $0.1 million, respectively, received from award recipients as payment in cash for the exercise price to purchase the equivalent number of newly-issued AB Units.

Assets and liabilities of foreign subsidiaries are translated from functional currencies into United States dollars (“US$”) at exchange rates in effect at the balance sheet dates, and related revenues and expenses are translated into US$ at average exchange rates in effect during each period. Net foreign currency gains and losses resulting from the translation of assets and liabilities of foreign operations into US$ are reported as a separate component of other comprehensive income in the consolidated statements of comprehensive income. Net foreign currency transaction losses were $8.5 million, $3.3 million and $2.0 million for 2021, 2020 and 2019, respectively, and are reported in general and administrative expenses on the consolidated statements of income.

AB is required to distribute all of its Available Cash Flow, as defined in the AB Partnership Agreement, to its Unitholders and to the General Partner. Available Cash Flow can be summarized as the cash flow received by AB from operations minus such amounts as the General Partner determines, in its sole discretion, should be retained by AB for use in its business, or plus such amounts as the General Partner determines, in its sole discretion, should be released from previously retained cash flow.

Typically, Available Cash Flow has been the adjusted diluted net income per unit for the quarter multiplied by the number of general and limited partnership interests at the end of the quarter. In future periods, management anticipates that Available Cash Flow will be based on adjusted diluted net income per unit, unless management determines, with the concurrence of the Board, that one or more adjustments that are made for adjusted net income should not be made with respect to the Available Cash Flow calculation.

On February 11, 2022, the General Partner declared a distribution of $1.38 per AB Unit, representing a distribution of Available Cash Flow for the three months ended December 31, 2021. The General Partner, as a result of its 1% general partnership interest, is entitled to receive 1% of each distribution. The distribution is payable on March 17, 2022 to holders of record on February 22, 2022.

We report all changes in comprehensive income in the consolidated statements of comprehensive income. Comprehensive income includes net income, as well as foreign currency translation adjustments, actuarial gains (losses) and prior service cost. Deferred taxes were not recognized on foreign currency translation adjustments for foreign subsidiaries which had earnings that were considered permanently invested outside the United States.

During 2021, amounts previously presented on the Statement of Cash Flows as (increase) decrease in right-of-use assets and increase (decrease) in lease liabilities are now presented net as "Cash payments to relieve operating lease liabilities". Non-cash lease expense under adjustments to reconcile net income to net cash provided by operating activities formerly classified as "Depreciation and other amortization" are now classified separately on the Statement of Cash Flows as "Non-cash lease expense." Prior period amounts previously presented as such have been reclassified to conform to the current period's presentation.
