During the second quarter of 2018, EQH completed the IPO, and as a result AXA owns approximately 71.9%72% of the outstanding common stock of EQH as of JuneSeptember 30, 2018. AXA has announced its intention to sell its entire interest in EQH over time, subject to market conditions and other factors. AXA is under no obligation to do so and retains the sole discretion to determine the timing of any future sales of shares of EQH common stock.

AllianceBernstein Corporation (an indirect wholly-owned subsidiary of EQH, “General Partner”) is the general partner of both AB Holding and AB. AllianceBernstein Corporation owns 100,000 general partnership units in AB Holding and a 1% general partnership interest in AB.

As of JuneSeptember 30, 2018, the ownership structure of AB, expressed as a percentage of general and limited partnership interests, is as follows:

The interim condensed financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the interim results, have been made. The preparation of the condensed 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 condensed financial statements and the reported amounts of revenues and expenses during the interim reporting periods. Actual results could differ from those estimates. The condensed statement of financial condition as of December 31, 2017 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”).

AB Holding records its investment in AB using the equity method of accounting. AB Holding’s investment is increased to reflect its proportionate share of income of AB and decreased to reflect its proportionate share of losses of AB and cash distributions made by AB to its Unitholders. In addition, AB Holding's investment is adjusted to reflect its proportionate share of certain capital transactions of AB.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, which outlines a single comprehensive revenue recognition model for all contracts with customers and supersedes most of the existing revenue recognition requirements. This standard had no impact on AB Holding’s statement of income. AB adopted this new standard on January 1, 2018 on a modified retrospective basis for contracts that were not completed as of the date of adoption.

On January 1, 2018, AB recorded a cumulative effect adjustment, net of tax, of a $35.0 million increase to partners’ capital in its condensed consolidated statement of financial condition. Accordingly, AB Holding, , as a result of its 35.5% ownership interest in AB as of January 1, 2018, recorded a cumulative effect adjustment, net of tax, of $12.5 million to partners’ capital in its condensed statement of financial condition.

AB maintains several unfunded, non-qualified long-term incentive compensation plans, under which the company grants awards of restricted AB Holding Units to its employees and members of the Board of Directors, who are not employed by AB or by any of AB’s affiliates (“Eligible Directors”).

AB funds its 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 AB Holding 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 the three and sixnine months ended JuneSeptember 30, 2018, AB purchased approximately 1.21.6 million and 1.22.9 million AB Holding Units for $32.9$48.0 million and $35.2$83.2 million, respectively (on a trade date basis). These amounts reflect open-market purchases of 1.21.6 million and 2.8 million AB Holding Units for $32.9$48.0 million during the second quarter of 2018and $80.9 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. During the three and sixnine months ended JuneSeptember 30, 2017, AB purchased 4.30.3 million and 5.75.9 million AB Holding Units for $96.7$6.9 million and $127.8$134.6 million, respectively (on a trade date basis). These amounts reflect open-market purchases of 3.70.3 million and 4.95.2 million AB Holding Units for $82.4$6.8 million and $110.3$117.1 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.

Each quarter, AB considers 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 selected by AB has the authority under the terms and limitations specified in the plan to repurchase AB Holding Units on AB’s 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 secondthird quarter of 2018 expired at the close of business on July 25,October 22, 2018. AB may adopt additional plans in the future to engage in open-market purchases of AB Holding Units to help fund anticipated obligations under its incentive compensation award program and for other corporate purposes.

During the first sixnine months of 2018 and 2017, AB granted to employees and Eligible Directors 2.42.5 million and 2.02.1 million restricted AB Holding Unit awards, respectively. AB used AB Holding Units repurchased during the periods and newly-issued AB Holding Units to fund these restricted AB Holding Unit awards.

Basic net income per unit is derived by dividing net income by the basic weighted average number of units outstanding for each period. Diluted net income per unit is derived by adjusting net income for the assumed dilutive effect of compensatory options (“Net income – diluted”) and dividing by the diluted weighted average number of units outstanding for each period.

Changes in AB Holding’s investment in AB during the six-monthnine-month period ended JuneSeptember 30, 2018 are as follows (in thousands):

AB Holding is a “grandfathered” publicly-traded partnership (“PTP”) for federal tax purposes and, accordingly, is not subject to federal or state corporate income taxes. However, AB Holding is subject to the 4.0% New York City unincorporated business tax (“UBT”), net of credits for UBT paid by AB, and to a 3.5% federal tax on partnership gross income from the active conduct of a trade or business. AB Holding’s partnership gross income is derived from its interest in AB.

AB Holding’s federal income tax is computed by multiplying certain AB qualifying revenues (primarily U.S. investment advisory fees and brokerage commissions) by AB Holding’s ownership interest in AB, multiplied by the 3.5% tax rate. AB Holding Units in AB’s consolidated rabbi trust are not considered outstanding for purposes of calculating AB Holding’s ownership interest in AB.

In order to preserve AB Holding’s status as a “grandfathered” PTP for federal income tax purposes, management ensures that AB Holding does not directly or indirectly (through AB) enter into a substantial new line of business. If AB Holding were to lose its status as a “grandfathered” PTP, it would be subject to corporate income tax, which would reduce materially AB Holding’s net income and its quarterly distributions to AB Holding Unitholders.

Legal and regulatory matters described below pertain to AB and are included here due to their potential significance to AB Holding's investment in AB.

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.

AB may be involved in various matters, including regulatory inquiries, administrative proceedings and litigation, some of which may allege significant damages. It is reasonably possible that AB could incur losses pertaining to these matters, but management cannot currently estimate any such losses.
