On September 12, 2007, the Department of Labor published in the Federal Register proposed ERISA guidance with respect to the selection of an annuity contract as an optional form of distribution in a defined contribution plan. Effective November 13, 2007, and in accordance with the Pension Protection Act, DOL amended its Interpretive Bulletin 95-1, articulating the so-called "safest available annuity" rule, to apply only to defined benefit plans. The DOL also proposed new safe harbor regulations elaborating the application of ERISA's prudence standard to a plan fiduciary's selection of an annuity as an optional form of distribution from a defined contribution plan.
