AT&T Umbrella Benefit Plan No. 1

AT&T Umbrella Benefit Plan No. 1

The AT&T Umbrella Benefit Plan No. 1 was established on January 1, 2001, as a centralized welfare benefit plan sponsored by AT&T Inc., the Dallas-based telecommunications giant. The plan does not manage a portfolio of external investments in the manner of a defined-benefit pension or an endowment. Instead, it functions as a funding and administrative vehicle for employee health and welfare benefits, encompassing component programs such as the AT&T Mobility Disability Benefits Program and AT&T CarePlus. As a welfare plan, the vehicle's primary activity involves maintaining trust assets earmarked for benefit disbursements rather than pursuing return-seeking allocations across asset classes. There is no publicly available evidence of direct co-investments, fund commitments, venture activity, or a diversified portfolio. The trust assets are tied to the operational obligations of AT&T's benefits ecosystem, which historically intersected with major corporate transactions. A disclosed linkage exists with WarnerMedia, a former AT&T subsidiary, and Discovery, Inc., following the WarnerMedia spin-off governed by an Employee Matters Agreement. The plan also supports a specific program for The CW Network. Publicly disclosed structural metrics — total assets in the welfare benefit trust, the number of covered lives, or annual disbursement figures — are not available. The plan's adjacent entities include the component programs it administers rather than separate investment vehicles or philanthropic foundations. There is no operational event in the last 24 months verifiable from current sources that altered the plan's public posture or administrative framework. Structurally, the plan is distinguished by its legal identity as a segregated welfare benefit trust, not a pension fund or operating foundation. Its relationship to the sponsor, AT&T Inc., is purely tied to the corporate balance sheet's benefit liabilities, making it a creditor of the parent rather than a pool of discretionary capital. Its governance and investment activity remain internal corporate functions with no external reporting mandate.
