This document is about a performance audit conducted by the U.S. Department of Labor's Employee Benefits Security Administration on the investment operations of the Thrift Savings Plan's Government Securities Investment Fund (TSP G Fund). The audit found that the U.S. Department of the Treasury and the Federal Retirement Thrift Investment Board implemented procedures to accurately calculate and report the G Fund interest rate and investments, as well as properly notify and restore the G Fund during debt issuance suspension periods, and the audit did not identify any instances of noncompliance with the relevant laws and regulations.
