Summary of Significant Accounting Policies

Basis of Presentation

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.

Principles of Consolidation

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 for which AB is considered the primary beneficiary. Non-controlling interests on the consolidated statements of financial condition includes 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.

Revision

During the third quarter of 2016, management determined that the frequency with which we settle our U.S. inter-company payable balances with foreign subsidiaries over the past several years created deemed dividends under Section 956 of the U.S. Internal Revenue Code of 1986, as amended ("Section 956"). In the past, we funded our foreign subsidiaries as they required cash for their operations rather than pre-fund them each quarter, thereby reducing the inter-company balance to zero on a quarterly basis, as required by Section 956. As a result, we have been understating our income tax provision and income tax liability since 2010. We evaluated the aggregate effects of this error in our income tax provision and income tax liability to our previously issued financial statements in accordance with SEC Staff Accounting Bulletins No. 99 and No. 108 and, based upon quantitative and qualitative factors, have determined that the error was not material to our previously issued financial statements. However, the cumulative effect of this error would have been material to our third quarter 2016 financial results if recorded as an out-of-period adjustment in the third quarter of 2016. Accordingly, we revised our previously issued financial statements by recording a cumulative debit adjustment of $12.6 million to our January 1, 2012 partners' capital account and revised our consolidated statements of financial condition and consolidated statements of income from 2012 through the second quarter of 2016. We established an income tax liability, including interest and potential penalties, of $34.2 million as of December 31, 2016. As of December 31, 2015, 2014 and 2013, the cumulative impact of the revision on partners’ capital in the statement of financial condition was $37.7 million, $31.0 million and $24.5 million, respectively. We revised our income tax provision, net income attributable to AB Unitholders, and basic and diluted net income per AB Unit reported in prior periods in the statements of income. The tables below reflect the revisions to these line items for the years ended December 31, 2015 and 2014 presented in this Form 10-K:



	Year Ended December 31, 2015
	As Reported		Adjustment			As Revised
	(in thousands, except per unit amounts)

Income taxes	$	38,122	$	6,675		$	44,797
Net income attributable to AB Unitholders	586,602		(6,675		)	579,927
Basic net income per AB Unit	2.14		(0.03		)	2.11

Recently Adopted Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entities Ability to Continue as a Going Concern, which requires management to assess, on a quarterly basis, a company’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. We adopted this standard on December 31, 2016. The adoption of this standard had no impact on our financial condition or results of operations.

In February 2015, the FASB issued ASU 2015-02, Consolidation – Amendments to the Consolidation Analysis ("ASU 2015-02"), which provides a new consolidation standard for evaluating: (i) limited partnerships and similar entities for consolidation, (ii) how decision maker or service provider fees affect the consolidation analysis, (iii) how interest held by related parties affects the consolidation analysis and (iv) how the consolidation analysis applies to certain investment funds. We adopted ASU 2015-02 using the modified retrospective method with an effective adoption date of January 1, 2016, which did not require the restatement of prior-year periods. The adoption of ASU 2015-02 resulted in the consolidation of certain investment funds that were not previously consolidated. These funds became consolidated VIEs because we are considered the party with both (i) the power to direct the activities of the VIE that most significantly impact its economic performance and (ii) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. See Consolidation of VIEs below.

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. This standard requires debt issuance costs be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. We adopted this standard on January 1, 2016 on a retrospective basis, which required the restatement of prior periods. The adoption of this standard did not have a material impact on our financial condition or results of operations.

In May 2015, the FASB issued ASU 2015-07, Fair Value Measurement: Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). This standard removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value ("NAV") per share practical expedient. We adopted this standard on January 1, 2016 on a retrospective basis, which required the restatement of prior-period disclosures. The adoption of this standard did not have a material impact on our financial condition or results of operations.

Accounting Pronouncements Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The amendment is effective retrospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2017. Management currently is evaluating the impact that the adoption of this standard will have on our consolidated financial statements. We have not yet completed this analysis, but based on the analysis completed to date management does not expect the standard to have a material impact on our financial condition or results of operations.

In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The amendment addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments and is effective for fiscal years (and interim periods within those years) beginning after December 15, 2017. The amendment will result in a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, except for one provision relating to equity securities without readily determinable fair values, which provision will be applied prospectively. The amendment is not expected to have a material impact on our financial condition or results of operations.

In February 2016, the FASB issued ASU 2016-02, Leases. The amendment requires recognition of lease assets and lease liabilities on the statement of financial condition and disclosure of key information about leasing arrangements. Specifically, this guidance requires an operating lease lessee to recognize on the statement of financial condition a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. However, for leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities. The amendment is effective for fiscal years (and interim periods within those years) beginning after December 15, 2018 and requires lessees to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. Management currently is evaluating the impact that the adoption of this standard will have on our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-07, Investments - Equity Method and Joint Ventures: Simplifying the Transition to the Equity Method of Accounting. The amendment eliminates the current requirement for a retroactive adjustment and instead requires that the investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Additionally, the amendment requires that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendment is effective for fiscal years (and interim periods within those years) beginning after December 15, 2016 and should be applied prospectively as of the effective date of increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. The amendment is not expected to have a material impact on our financial condition or results of operations.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. The amendment includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements, including income tax effects of share-based payments, minimum statutory tax withholding requirements and forfeitures. The amendment is effective for fiscal years (and interim periods within those years) beginning after December 15, 2016 and may be applied using various transition approaches (prospective, retrospective and modified retrospective). The amendment is not expected to have a material impact on our financial condition or results of operations.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). The amendment is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The amendment is effective for fiscal years (and interim periods within those years) beginning after December 15, 2017 and should be applied using a retrospective transition method. The amendment is not expected to have a material impact on our financial condition or results or operations.

Consolidation of VIEs

As discussed above, we adopted ASU 2015-02 effective January 1, 2016.

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 fees are compensation for services provided 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 voting interest entity (“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.

The analysis performed regarding the determination of variable interests held, whether entities are VIEs or VOEs, and whether we have a controlling financial interest in such entities requires the exercise of judgment. The analysis is updated continuously as circumstances change or new entities are formed.

As a result of the adoption of ASU 2015-02, effective January 1, 2016, we consolidated three investment funds that were classified as VIEs in which we have a controlling financial interest. Ownership interests not held by us relating to these consolidated VIEs are included in redeemable non-controlling interest on the condensed consolidated statement of financial condition. In addition, effective January 1, 2016, we reclassified our consolidated private equity fund as a consolidated VIE, which had been consolidated as of December 31, 2015 under previous accounting guidance due to our controlling financial interest of a VOE. Ownership interests not held by us relating to this consolidated VIE, which is a closed-end fund, are included in non-controlling interest on the consolidated statement of financial condition.

During 2016, subsequent to the initial adoption of ASU 2015-02, we consolidated six additional investment funds that were classified as VIEs in which we have a controlling interest and deconsolidated a VIE of which we were no longer the primary beneficiary. The table below illustrates the summary balance sheet amounts related to these VIEs at their consolidation dates:



	January 1, 2016		Year Ended December 31, 2016
	ASU 2015-02 Adoption		VIEs Consolidated		VIEs De-consolidated

Cash and cash equivalents	$	35,817	$	371,457	$	(12,923	)
Investments	215,175		85,381		(125,636		)
Other assets	13,871		23,473		(59,684		)
Total assets	$	264,863	$	480,311	$	(198,243	)

Liabilities	$	14,012	$	41,245	$	(60,332	)
Redeemable non-controlling interest	250,851		394,102		(137,911		)
Partners' capital	—		44,964		—
Total liabilities, redeemable non-controlling interest and partners' capital	$	264,863	$	480,311	$	(198,243	)

As of December 31, 2016, the net assets of company-sponsored investment products that are non-consolidated VIEs are approximately $43.7 billion, and our maximum risk of loss is our investment of $13.0 million in these VIEs and advisory fee receivables from these VIEs, which are not material.

Cash and Cash Equivalents

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. The majority of our consolidated VIEs' cash and cash equivalents is pledged as collateral for short equities.

Fees Receivable, Net

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.

Brokerage Transactions

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, 2016, there were no re-pledged securities. 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, 2016 and 2015. 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, 2016 and 2015, 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, 2016 and 2015, we had $41.7 million and $81.4 million, respectively, of cash on deposit with clearing organizations for trade facilitation purposes. In addition, as of December 31, 2016 and 2015, we held U.S. Treasury Bills with values totaling $28.9 million and $24.9 million, respectively, in our investment account that are pledged as collateral with clearing organizations. These clearing organizations have the ability by contract or custom to sell or re-pledge this collateral.

Investments

Investments include U.S. Treasury Bills, unconsolidated mutual funds and limited partnership hedge funds we sponsor and manage, various separately-managed portfolios consisting of equity and fixed income securities, exchange-traded options and investments owned by a consolidated venture capital fund in which we own a controlling interest as the general partner and a 10% limited partnership interest.

Investments in U.S. Treasury Bills, mutual funds, and equity and fixed income securities are classified as either trading or available-for-sale securities. Trading investments are stated at fair value with unrealized gains and losses reported in investment gains and losses on the consolidated statements of income. Available-for-sale investments are stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income in partners’ capital. Realized gains and losses on the sale of investments are reported in investment gains and losses on the consolidated statements of income. Average cost is used to determine realized gain or loss on investments sold.

We use the equity method of accounting for investments in limited partnership hedge funds. The equity in earnings of our limited partnership hedge fund investments is reported in investment gains and losses on the consolidated statements of income.

The investments owned by our consolidated venture capital fund generally are illiquid and initially are valued at cost. These investments are adjusted to fair value to reflect the occurrence of “significant developments” (i.e., capital transactions or business, economic or market events). Adjustments to fair value are reported in investment gains and losses on the consolidated statements of income. There are two private equity investments that we own directly outside of our consolidated venture capital fund accounted for at fair value.

See Note 9 for a description of how we measure the fair value of our investments.

Furniture, Equipment and Leasehold Improvements, Net

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.

Goodwill

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.

As of December 31, 2016, goodwill of $3.1 billion on the consolidated statement of financial condition included $2.8 billion as a result of the Bernstein acquisition and $266 million in regard to various smaller acquisitions. We have determined that AB has only one reporting segment and reporting unit.

We test our goodwill annually, as of September 30, for impairment. As of September 30, 2016, the impairment test indicated that goodwill was not impaired. We also review the carrying value of goodwill if facts and circumstances occur that suggest possible impairment, such as significant declines in AUM, revenues, earnings or the price of an AB Holding Unit. There were no facts or circumstances occurring in the fourth quarter of 2016 suggesting possible impairment.

Intangible Assets, Net

Intangible assets consist primarily of costs assigned to acquired investment management contracts of Bernstein 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 six years to 20 years.

As of December 31, 2016, intangible assets, net of accumulated amortization, of $134.6 million on the consolidated statement of financial condition consisted of $121.1 million of definite-lived intangible assets subject to amortization, of which $77.6 million relates to the Bernstein acquisition, and $13.5 million of indefinite-lived intangible assets not subject to amortization in regard to other acquisitions. As of December 31, 2015, intangible assets, net of accumulated amortization, of $145.7 million on the consolidated statement of financial condition consisted of $132.2 million of definite-lived intangible assets subject to amortization, of which $98.3 million related to the Bernstein acquisition, and $13.5 million of indefinite-lived intangible assets not subject to amortization in regard to other acquisitions. The gross carrying amount of definite-lived intangible assets totaled $476.1 million as of December 31, 2016 and $460.8 million as of December 31, 2015, and accumulated amortization was $355.0 million as of December 31, 2016 and $328.6 million as of December 31, 2015. Amortization expense was $26.3 million for 2016, $25.8 million for 2015 and $24.9 million for 2014. Estimated annual amortization expense for each of the next three years is approximately $28 million, then approximately $20 million in year four and $5 million in year five.

We periodically review 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.

Deferred Sales Commissions, Net

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 five and one-half years 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 contingent deferred sales commissions (“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. As of December 31, 2016, our Non-U.S. Funds are no longer offering back-end load shares, except in isolated instances.

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 2016 or 2015.

Loss Contingencies

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.

Revenue Recognition

We record as revenue investment advisory and services fees, which we generally calculate as a percentage of AUM, as we perform the related services. Certain investment advisory contracts, including those associated with hedge funds or other alternative investments, provide for a performance-based fee, 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. We record performance-based fees as a component of revenue at the end of each contract’s measurement period.

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, evaluation of assets versus liabilities 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.

Bernstein Research Services revenues consist primarily of brokerage commissions for research and brokerage-related services provided to institutional investors. Brokerage commissions earned and related expenses are recorded on a trade-date basis.

Distribution revenues, shareholder servicing fees (included in other revenues), and dividend and interest income are accrued as earned.

Contingent Payment Arrangements

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.

Mutual Fund Underwriting Activities

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 trade date. Receivables from brokers and dealers for sale of shares of company-sponsored mutual funds generally are realized within three business days from 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.

Long-term Incentive Compensation Plans

We maintain several unfunded, non-qualified long-term incentive compensation plans, under which we grant annual awards to employees, generally in the fourth quarter.

Awards granted in December 2016, 2015 and 2014 allowed 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 up to 100% of his or her award to deferred cash. Participants allocated their awards prior to the date on which the Compensation Committee granted awards in December 2016, 2015 and 2014. 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 2016, 2015 and 2014:


•	We engage in open-market purchases of AB Holding Units or purchase newly-issued AB Holding Units from AB Holding that are awarded to participants and keep them in a consolidated rabbi trust.


•	Quarterly distributions on vested and unvested AB Holding Units are paid currently to participants, regardless of whether or not a long-term deferral election has been made.


•	Interest on deferred cash is accrued monthly based on our monthly weighted average cost of funds.

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 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 four years, unless the employee has made a long-term deferral election.

Grants of restricted AB Holding Units and options to buy AB Holding Units typically are awarded during the second quarter 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”). Restricted AB Holding Units are delivered on the third anniversary of the grant date and the options become exercisable ratably over three years. These restricted AB Holding Units and options 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 all of 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.

During 2016 and 2015, we purchased 10.5 million and 8.5 million AB Holding Units for $236.6 million and $218.3 million, respectively (on a trade date basis). These amounts reflect open-market purchases of 7.9 million and 5.8 million AB Holding Units for $176.1 million and $151.1 million, respectively, with the remainder relating to purchases of AB Holding Units from employees to allow them to fulfill statutory tax withholding requirements at the time of delivery of long-term incentive compensation awards. Purchases of AB Holding Units reflected on the consolidated statements of cash flows are net of AB Holding Units purchased by employees as part of a distribution reinvestment election.

Each quarter, we consider whether to implement a plan to repurchase AB Holding Units pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (“Exchange Act”). A Rule 10b5-1 plan 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 under the terms and limitations specified in the plan to repurchase AB Holding Units on our behalf in accordance with the terms of 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. The plan adopted during the fourth quarter of 2016 expired at the close of business on February 10, 2017. We may adopt additional Rule 10b5-1 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 2016, we granted to employees and Eligible Directors 7.0 million restricted AB Holding Unit awards (including 6.1 million granted in December for 2016 year-end awards to employees). During 2015, we granted to employees and Eligible Directors 7.4 million restricted AB Holding Unit awards (including 7.0 million granted in December for 2015 year-end awards to employees).

During 2016 and 2015, AB Holding issued 0.4 million and 0.5 million AB Holding Units, respectively, upon exercise of options to buy AB Holding Units. AB Holding used the proceeds of $6.1 million and $9.2 million, respectively, received from employees as payment in cash for the exercise price to purchase the equivalent number of newly-issued AB Units.

Foreign Currency Translation and Transactions

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 gains (losses) were $1.1 million, $1.0 million, and $(1.6) million for 2016, 2015 and 2014, respectively, and are reported in general and administrative expenses on the consolidated statements of income.

Cash Distributions

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 that one or more non-GAAP adjustments that are made for adjusted net income should not be made with respect to the Available Cash Flow calculation.

On February 14, 2017, the General Partner declared a distribution of $0.73 per AB Unit, representing a distribution of Available Cash Flow for the three months ended December 31, 2016. 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 9, 2017 to holders of record on February 24, 2017.

Total cash distributions per Unit paid to the General Partner and Unitholders during 2016, 2015 and 2014 were $1.98, $2.18 and $2.11, respectively.

Comprehensive Income

We report all changes in comprehensive income in the consolidated statements of comprehensive income. Comprehensive income includes net income, as well as unrealized gains and losses on investments classified as available-for-sale, foreign currency translation adjustments, and unrecognized actuarial net losses and transition assets. Deferred taxes are not recognized on foreign currency translation adjustments for foreign subsidiaries whose earnings are considered permanently invested outside the United States.
