The Railroad Retirement Board's Office of Programs should, in coordination with the Bureau of Field Service, determine, develop, and document policies and procedures including end-to-end business processes for its Railroad Retirement Act annuity payments. Those procedures should include: (a) an implementation of a checklist when reviewing and accepting employee applications for benefits payments that must be signed by the appropriate preparer and reviewer; (b) requirement that all eligibility documentation is complete and accessible; and (c) the development of an in-depth guide that outlines how the Payment Rate Entitlement History (PREH) completes the benefit payment calculations.
