A SERP is an employer-sponsored, non-qualified deferred compensation plan, where you agree to provide supplemental retirement income to selected key executives. You may wish to include a vesting schedule on these benefits to encourage your executives to remain employed with your institution. Some plans may allow for distributions while the executive is still employed and may even offer survivor benefits should the executive die before the SERP benefits are fully distributed. A SERP is a valuable compensation and benefit tool for attracting, retaining, and rewarding key members of your leadership team.
