593 Investments

593.1 Funds Available

TSP is composed of six funds: the Government Securities Investment Fund (G Fund), the Fixed Income Index Investment Fund (F Fund), the Common Stock Index Investment Fund (C Fund), the Small Capitalization Stock Index Investment Fund (S Fund), International Stock Index Investment Fund (I Fund), and Lifecycle Funds (L Funds).

  1. The G Fund consists exclusively of investments in short-term nonmarketable U.S. Treasury securities specially issued to the TSP. G Fund investments earn guaranteed interest at a rate that is equal to the average of market rates of return on U.S. Treasury securities with 4 or more years to maturity. The interest is calculated monthly.
  2. The F, C, S, and I funds are index funds. The TSP invests each fund proportionately to replicate the risk-and-return performance of the fund’s benchmark index.
  3. The L funds are invested in the five individual TSP funds (G, F, C, S, and I) based on professionally determined asset allocations. The objective is to strike an optimal balance between the expected risk and return associated with each fund.

593.2 Investment Options

593.21 Fund Allocation

Employees may allocate their TSP contributions, including agency contributions, among the six investment funds. Employees must make fund allocations in whole dollars or whole percentage of the employee’s basic pay.

Contributions of employees who do not make a contribution allocation for their TSP funds will be invested according to the following rules:

  1. For employees enrolled on or after September 5, 2015, all their contributions the TSP received will be deposited into the Lifecycle (L) Fund targeted most closely to the year they turn 62.
  2. For employees enrolled before September 5, 2015, all contributions to their account are deposited into the Government Securities Investment (G) Fund, until the employee elects another investment option.
593.22 Changing Investments

Employees can request to change the allocation of contributions at any time via telephone or online. (See 591.12 for more information.)

593.23 Interfund Transfers

An interfund transfer is the movement of money already in the employee’s account among the investment funds. This movement does not affect contributions from future payroll deductions. Employees are allowed one interfund transfer per month, using the TSP ThriftLine or submitting TSP-30, Interfund Transfer Request, to the TSP Service office.

593.3 Participant Statements

593.31 Frequency

TSP issues an individualized participant statement to each participating employee after the end of each calendar quarter. Calendar quarters end March 31, June 30, September 30, and December 31.

593.32 Contents

The TSP quarterly participant statement provides valuable information about the employee’s account. It covers all transactions for the account during the past three months. Because the statement replicates the information in the employee’s TSP record, it is important that employees review it and report any incorrect information to the TSP.

593.33 Distribution

The TSP mails the first quarterly statement to employees. After that, TSP statements are available online at www.tsp.gov. In addition, employees can request that the TSP mail them quarterly statements. The TSP will send mailed statements to the address of record on file. Employees can update their address through Blue or LiteBlue or by submitting PS Form 1216, Employee’s Current Mailing Address, to the HRSSC.
