Report on the Operation and Status of the

Government Securities Investment Fund

March 17, 2015 to November 3, 2015

Pursuant to 5 U.S.C. § 8438(h)

December 1, 2015

On March 16, 2015, the outstanding debt subject to the limit was at the statutory debt limit. In 

order to protect the full faith and credit of the United States, beginning on March 17, 2015, the 

Secretary of the Treasury employed statutory authority to suspend investments in the Government 

Securities Investment Fund (G Fund) of the Federal Employees’ Retirement System. The

Bipartisan Budget Act of 2015 (Pub L. 114-74) operated to suspend the statutory limit beginning 

November 2, 2015, rendering further use of this authority unnecessary. The G Fund was fully 

restored by November 3, 2015. 

Legal authority: Section 8438(g)(1) of Title 5, United States Code, empowers the Secretary of the 

Treasury to “suspend the issuance of additional amounts of obligations of the United States [to

this fund], if such issuances could not be made without causing the public debt of the United 

States to exceed the public debt limit.” The statute defines the period of this suspension as a 

“debt issuance suspension period.” § 8438(g)(6)(B).

Reporting requirement: Section 8438(h) requires submission of a report to Congress on the 

operation and status of the G Fund during this period. The report is to be made “as soon as 

possible after the expiration of such period, but not later than 30 days after the first business day 

after the expiration of such period.” § 8438(h)(2). This document fulfills the requirement of 

section 8438(h). A copy of this report is being concurrently transmitted to the Executive Director 

of the Federal Retirement Thrift Investment Board.

Restoration requirement: Section 8438(g) requires the Secretary to make the G Fund whole upon 

expiration of a debt issuance suspension period. Treasury must issue obligations sufficient to 

ensure that the G Fund’s portfolio replicates what it would have been upon the expiration of the 

period, as if the suspension had not occurred. § 8438(g)(3). Treasury must also pay the G Fund

an amount equal to the interest that the fund would have earned. § 8438(g)(4).

Status and operations: Throughout this period, a portion of the G Fund’s holdings could not be 

re-invested without exceeding the debt limit. Treasury has now replicated the portfolio the G 

Fund would have held but for the suspension, and has paid the G Fund $1,716,577,385.43 for 

interest it would have earned, accounting for receipts and withdrawals.

The table included as Attachment 1 details the daily and cumulative amounts of G Fund principal 

and interest that were suspended and restored. With the restoration of $204,838,603,264.34 in 

principal on November 2, 2015 and $1,716,577,385.43 in interest on November 3, 2015, the G 

Fund was fully restored to the condition it would have been in had there not been a debt issuance 

suspension period.
