Share-Based Payment Arrangement [Abstract] |
Long-term Incentive Compensation Plans | Long-term Incentive Compensation Plans AB has several unfunded, non-qualified long-term incentive compensation plans, under which we grant awards of restricted units representing assignments of beneficial ownership of limited partnership interests in AB Holding (“AB Holding Units”) 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”). AB Holding Units are maintained in a consolidated rabbi trust either by purchasing AB Holding Units on the open market or by purchasing newly-issued AB Holding Units from AB Holding 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. Repurchases of AB Holding Units for the three and nine months ended September 30, 2025 and 2024 consisted of the following:
|  | Three Months Ended September 30, |  | Nine Months Ended September 30,
|  | 2025 |  | 2024 |  | 2025 |  | 2024
|  | (in millions)
Total amount of AB Holding Units Purchased (1) |  | 0.1 |  |  | 1.1 |  |  | 1.3 |  |  | 2.1 |
Total Cash Paid for AB Holding Units Purchased (1) |  | $ | 4.1 |  |  | $ | 38.6 |  |  | $ | 47.8 |  |  | $ | 71.7 |
Open Market Purchases of AB Holding Units Purchased (1) |  | 0.1 |  |  | 1.1 |  |  | 1.1 |  |  | 1.8 |
Total Cash Paid for Open Market Purchases of AB Holding Units (1) |  | $ | 3.9 |  |  | $ | 38.6 |  |  | $ | 42.3 |  |  | $ | 60.1 |
(1) Purchased on a trade date basis. The difference between open-market purchases and total amount of units purchased reflects the retention of AB Holding Units from employees 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. 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 third quarter of 2025 expired at the close of business on October 22, 2025. AB may adopt additional plans in the future to engage in open-market purchases of AB Holding Units for anticipated obligations under its incentive compensation award program and for other corporate purposes. During the first nine months of 2025 and 2024, AB awarded to employees and Eligible Directors 1.6 million and 1.2 million restricted AB Holding Unit awards, respectively. AB used AB Holding Units repurchased during the applicable period and newly-issued AB Holding Units for these restricted AB Holding Unit awards.

- Definition The entire disclosure for compensation costs, including compensated absences accruals, compensated absences liability, deferred compensation arrangements and income statement compensation items. Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability. + References Reference 1: http://www.xbrl.org/2003/role/disclosureRef -Topic 710 -SubTopic 10 -Name Accounting Standards Codification -Section 50 -Paragraph 1 -Publisher FASB -URI https://asc.fasb.org/1943274/2147482969/710-10-50-1 Reference 2: http://www.xbrl.org/2003/role/disclosureRef -Topic 710 -Name Accounting Standards Codification -Publisher FASB -URI https://asc.fasb.org/710/tableOfContent + Details
