Va. Code § 15.2-1544
The governing body of any county, city, or town may establish a trust, trusts, or equivalent arrangements for the purpose of accumulating and investing assets to fund postemployment benefits other than pensions, as defined herein. Deposits to any such trust, trusts, or equivalent arrangements and any earnings on those deposits shall be irrevocable; shall be dedicated to providing benefits to retirees and their beneficiaries in accordance with the terms of the plans or programs providing postemployment benefits other than pensions; and shall be exempt from taxation and execution, attachment, garnishment, or any other process. For the purposes of this article, an equivalent arrangement shall mean any fund or similar arrangement established by the governing body pursuant to this article under which funds are irrevocably allocated, segregated, or otherwise dedicated to providing postemployment benefits other than pension benefits to retirees and their beneficiaries. The governing body of any such county, city, or town also may make appropriations to any such trust, trusts, or equivalent arrangements, and any such governing body may require active and former employees covered by a postemployment benefit plan or program to contribute to such a trust or equivalent arrangement through payments or deductions from their wages, salaries, or pensions. Officers and employees who are subject to inclusion in the retirement plans described in § 51.1-800 also may be included in any such trust, trusts, or equivalent arrangements by the governing body.
The governing body also may authorize the governing body of any other political subdivision that is appointed in whole or in part by the governing body of such county, city, or town, to establish and fund a trust, trusts, or equivalent arrangements for its active and former employees. Any appointed or elected school board may establish and fund such a trust, trusts, or equivalent arrangements for its active and former employees. The governing body of any county, city, or town also may enter into agreements with the appointed or elected school board that provides public schools within its boundaries or with any other political subdivision, which is appointed in whole or in part by the governing body of any such county, city, or town, to permit any such school board or such other political subdivision to participate in any trust, trusts, or equivalent arrangements established by the governing body of any such county, city, or town.
The governing body of any such county, city, or town, the school board of the local school divisions, and the governing body of any other political subdivision that establishes or participates in any such trust, trusts, or equivalent arrangements, shall have the right to revise or discontinue its plans or programs providing such postemployment benefits other than pensions for its active and former officers and employees as it may deem necessary or transfer any assets held in any trust or equivalent arrangement established pursuant to this article to any other trust, trusts, or equivalent arrangement established pursuant to this article; provided, however, any amendment, suspension, or revocation of any plans or programs providing such postemployment benefits other than pensions or transfer of assets held in a trust or equivalent arrangement shall not have the effect of diverting the assets of any trust, trusts, or equivalent arrangements to purposes other than the exclusive benefit of the active or former employees or their dependents or beneficiaries entitled to such postemployment benefit. If all plans or programs providing such postemployment benefits other than pensions for which a trust or equivalent arrangement is established are repealed or terminated by the governing body that created such trust, trusts or equivalent arrangements, then there shall be no continuing responsibility for that governing body to continue to make appropriations to such trust, trusts or equivalent arrangements, and the assets of any such trust, trusts or equivalent arrangements shall be used to provide any benefits continuing to be due to active or former employees (and their dependents or beneficiaries) under such plans or programs. If there are no active or former employees (or dependents or beneficiaries) due a benefit under any plan or program providing such postemployment benefits other than pensions for which the trust or equivalent arrangement was established, then any remaining assets may revert to the locality.
