BALANCES OF BUDGET AUTHORITY
Budget for Fiscal Year 2024
Government agencies are permitted to enter into obligations that result in immediate or future outlays only when they have been
granted authority to do so by law. This authority is called budget authority. This report presents the balances of budget authority for
the end of 2022, 2023 and 2024 as shown in the 2024 Budget.
Budget authority is placed in a budget account and is classified in either the “federal” funds group or the “trust” fund group. Trust
funds consist of accounts defined in law as a trust fund. The federal fund balances include all balances that are not required by law to
pass through trust funds.
Budget authority moves through stages. When budget authority is first enacted, it is called “new” budget authority. Thereafter, it is
called “balances” of budget authority.


Unobligated balances refers to balances that have not yet been committed by contract or other legally binding action by the
Government.



Obligated balances refers to balances for which there has been legally binding action (for example, contracts signed) and
payment has not yet been made but will be required to be made in the future.



Unexpended balances of budget authority refers to the sum of the unobligated and obligated balances.

At the end of each fiscal year, unobligated balances that remain available for new obligation are carried forward to the start of the next
fiscal year. Unobligated balances that are expiring (i.e., are not available for new obligation) are not carried forward to the start of the
next fiscal year. By law, obligated balances are either no-year or available to pay old bills normally for five expired years after which

the obligated balances are cancelled. Therefore, obligated balances that remain available to pay old bills are carried forward to the
start of the next fiscal year. This report provides data on the end of year balances that are not expiring and are carried forward to the
start of the next fiscal year in the following tables:
TABLE 1. SUMMARY OF UNEXPENDED BALANCES – shows total Federal Government obligated and unobligated balances
divided between federal funds and trust funds.
TABLE 2. TOTAL UNEXPENDED BALANCES BY AGENCY – shows total obligated and unobligated balances by Department
and major agency.
TABLE 3. FEDERAL FUND OBLIGATED BALANCES, BY AGENCY – shows federal fund obligated balances by Department
and major agency.
TABLE 4. FEDERAL FUND UNOBLIGATED BALANCES, BY AGENCY – shows federal fund unobligated balances by
Department and major agency.
TABLE 5. TRUST FUND OBLIGATED BALANCES, BY MAJOR TRUST FUND – shows obligated balances for the larger trust
funds.
TABLE 6. TRUST FUND UNOBLIGATED BALANCES, BY MAJOR TRUST FUND – shows unobligated balances for the larger
trust funds.
TABLE 7. TRUST FUND BRIDGE FROM UNEXPENDED BALANCES TO CASH – provides a bridge from trust funds’
unexpended balances of budget authority to unexpended cash, with a further adjustment for debt outstanding to calculate net position.
TABLE 8. CREDIT FINANCING ACCOUNTS UNOBLIGATED BALANCES – shows unobligated balances of credit financing
accounts, which are non-budget accounts that record the financing transactions associated with federal lending programs and hold
assets to cover estimated losses on direct loans and loan guarantees.
TABLE 9. UNOBLIGATED BALANCES BY PROGRAM CATEGORIES – groups unobligated balances of programs with similar
characteristics or purposes.

Total unexpended balances at the end of 2023 to be carried forward to 2024 is estimated to be $4,405 billion. Of this amount, 55% or
$2,416 billion is estimated to be obligated, and 45% or $1,989 billion is estimated to be unobligated.
This $1,989 billion in unobligated balances is similar to previous years. To provide more insight on the magnitude and composition of
these balances, Table 9 groups unobligated balances into the following major program categories.
I.
II.
III.
IV.
V.
VI.

Insurance and other financial reserves – $765 billion or 38% of the total;
Programs that require working capital – $88 billion or 4% of the total;
Programs funded by earmarked receipts or dedicated taxes – $277 billion or 14% of the total;
Prefunding of major appropriated entitlements – $54 billion or 3% of the total;
Programs with long lead times to outlay – $200 billion or 10% of the total; and
All other programs that account for the remaining $605 billion.

These categories are explained in more detail below.
I. INSURANCE AND OTHER FINANCIAL RESERVES. This program category accounts for $765 billion of the total estimated
unobligated balances to be carried forward to 2024. Of this major program category, 33% is for GSE preferred stock purchase
agreements; 21% is for deposit insurance programs; 10% is for health and life insurance funds for Federal employees; 8% is for
Pension Benefit Guaranty Corporation; 22% is for other insurance programs; and the last 6% is for international financial reserves.
a. GSE Preferred Stock Purchase Agreements. These agreements make up $254 billion of the total unobligated balances.
Section 1117 of the Housing and Economic Recovery Act of 2008 (HERA) granted authority for the Treasury to purchase any
obligations and other securities issued by Government Sponsored Enterprises (GSEs), specifically Fannie Mae and Freddie Mac.
The unobligated balances in the GSE Preferred Stock Agreement (PSPA) account exist in the event that in the future the GSEs
need financial support under the PSPAs.
b. Deposit Insurance. $163 billion of the unobligated balances are for the Federal Deposit Insurance Corporation (FDIC), the
National Credit Union Administration (NCUA) and the Treasury Department’s Office of the Comptroller of the Currency (OCC).

The FDIC has two accounts with large balances, the Deposit Insurance Fund (DIF) and the FSLIC Resolution Fund (FRF).




The primary purpose of the DIF is to insure deposits and protect the depositors of failed banking institutions. The
FDIC is authorized to charge risk-based premiums on member institutions to restore and maintain adequate DIF
reserves, which must be a designated percentage of estimated insured deposits as set by the FDIC before the beginning
of each year. The unobligated balance in the DIF is a reserve to resolve failed institutions, if necessary. FDIC, as
receiver of the failed institution, must liquidate assets of the failed institution that have declined substantially in value
while, at the same time, making good on the institution's deposit obligations.
The FRF is the ultimate successor to the Federal Savings and Loan Insurance Corporation (FSLIC) assets and liabilities
from thrift resolutions prior to August 1989, as well as Resolution Trust Corporation (RTC) that assumed the FSLIC's
unresolved cases through December 31, 1995. The FRF will terminate upon the disposition of all of its assets. Any net
proceeds will be deposited into the General Fund of the Treasury for net proceeds from the former FSLIC, while any
net proceeds from the former RTC will be paid to the Resolution Funding Corporation.

The National Credit Union Administration funds its activities through assessments levied on all federally chartered credit
unions and through reimbursements from the Share Insurance Fund (SIF) for its share of administrative activities. The
primary purpose of the SIF is to provide insurance for deposits of member accounts (also known as insured member shares) in
Federal credit unions and state-chartered credit unions that apply and qualify for insurance as authorized by Public Law 91–
468. The unobligated balances are reserves to pay insured members should a credit union fail
The Office of the Comptroller of the Currency (OCC) is funded primarily by assessments and fees paid by national banks,
as well as interest on investments in U.S. Government securities and other income. The OCC receives no appropriated funds
from Congress. Pursuant to the Comptroller's authority, the OCC's unobligated funds support the bureau's mission by reducing
the possible impact on OCC operations in the event of significant fluctuation in revenues and/or expenses, or as a result of
changes in risk at banks creating a need to reallocate resources. Within its unobligated balances, the OCC has maintained two
receivership contingency funds.

c. Health and life insurance funds for Federal employees. This category accounts for $79 billion of the total. It includes:
1. $73 billion for the Office of Personnel Management Employees Life Insurance Fund and Employees and Retired
Employees Health Benefits Fund;
2. $4 billion for the Department of Veterans Affairs’ Veterans Special Life, Service Disabled Veterans, Veterans Reopened,
and Service members’ Group Life Insurance Funds; and
3. $2 billion for the Department of Defense’s Defense Health Program.
In the case of the OPM Employees Life Insurance Fund, insured Federal employees (excluding Postal Service) and Federal
retirees under age 65 pay two-thirds of the premium costs for basic coverage; agenciespay the remaining third. Optional and
certain post-retirement basic coverage are paid entirely by enrollees. The unobligated balance represents collected premiums
and investment proceeds that will be used to pay benefits upon the death of enrollees. The Employees and Retired Employees
Heath Benefits Funds are financed by: 1) withholdings from active employees and annuitants; 2) agency contributions for
active employees; 3) Government contributions for annuitants appropriated to OPM; and 4) payments from the Postal Service
Retiree Health Benefits Fund. The unobligated balance represents funds made available to carriers but not used to pay claims
in the current period that are carried forward as reserves for use in subsequent periods.
d. Pension Benefit Guaranty Corporation. This account makes up $60 billion of the total. The Pension Benefit Guaranty
Corporation (PBGC) is a federal corporation established under the Employee Retirement Income Security Act of 1974, as
amended. It guarantees payment of basic pension benefits earned by nearly 33 million of America's workers and retirees
participating in more than 25,000 private sector defined benefit pension plans. PBGC’s insurance operations are financed by
insurance premiums paid by companies that sponsor defined benefit pension plans, investment income, and assets from terminated
plans. The American Rescue Plan (ARP) Act of 2021 established the Special Financial Assistance (SFA) Program for certain
financially troubled multiemployer pension plans. The SFA payments are derived from appropriated funds and financed by
general tax revenues.
e. Credit Liquidating Accounts. These accounts make up $1 billion of the total unobligated balances. Pursuant to the Federal
Credit Reform Act of 1990, the cash flows associated with pre-1992 direct loan obligations and loan guarantee commitments are
reported on a cash basis in liquidating accounts. Normally at the end of each year, the unobligated balances in credit liquidating
accounts are returned to the Treasury because the amounts can only be used to liquidate obligations incurred in the year the
amounts are collected. The balances that remain are reserves needed to pay claims should there be a default on a loan that was
guaranteed before the end of 1991.

f. Other Insurance. This category accounts for $164 billion of the total. It includes:
1. $154 billion for the Department of Housing and Urban Development’s FHA-mutual Mortgage Insurance Capital Reserve
and the Guarantees of Mortgage backed Securities Capital account;
2. $7 billion for the Farm Credit System Insurance Fund;
3. $2 billion for the Department of Transportation's Aviation War Risk insurance funds; and
4. $1 billion for the Federal Crop Insurance Corporation Fund.
U.S. International Development Finance Corporation (DFC) partners with the private sector to provide financing and
insurance solutions for the most critical challenges facing the developing world today. The DFC was created under the BUILD
Act of 2018 – consolidating the operations of its predecessor the Overseas Private Investment Corporation (OPIC), and the
lending programs of USAID into a modernized new agency. Unobligated balances in DFC’s accounts are amounts available to
pay future insurance and reinsurance claims.
g. International Financial Reserves. The Exchange Stabilization Fund and the Contribution to the International Bank for
Reconstruction and Development (IBRD) account for about $44 billion of the unobligated balances.
Exchange Stabilization Fund. Special Drawing Rights (SDRs) assets appear as unobligated balances in the Exchange
Stabilization Fund (ESF). These SDRs can be used either in transactions with the IMF, other members of the IMF, or for the
purposes of the ESF set forth in the ESF statutory authorization. The Secretary of the Treasury is authorized to use the ESF
assets – SDR, dollar and foreign currency assets – consistent with U.S. obligations in the IMF on orderly exchange
arrangements and a stable system of exchange rates. The principal sources of the ESF’s income have been SDR allocations,
unrealized gains on foreign exchange investments, interest on operations with foreign countries, and interest on investments
held by the ESF.

Contribution to the International Bank for Reconstruction and Development (IBRD). The unobligated balance reflects
reserves that are intended to be obligated and outlayed to meet obligations for funds loaned or for loans guaranteed by the
Bank, only if called on by the Bank in the event of insolvency. The funds representing the unobligated balance were
appropriated as budget authority under previous law and correspond to IBRD shareholding. The Bank has not made a call on
such callable capital to date.
II. PROGRAMS THAT REQUIRE WORKING CAPITAL. This category accounts for $88 billion of the total estimated
unobligated balances to be carried forward to 2024. It is made up of the public enterprise revolving funds and the intragovernmental
revolving funds that collect payments from the public or Federal government accounts in return for providing goods and services.
These accounts need working capital to produce the goods and services to sell to customers who will then reimburse the accounts.
The unobligated balances are necessary to allow this cycle of operations to continue.
III. PROGRAMS FUNDED BY EARMARKED RECEIPTS OR DEDICATED TAXES. This category accounts for $277
billion of the total estimated unobligated balances to be carried forward to 2024. The following make up 99.6% of these balances:


$43 billion are in the Department of Transportation. Of this amount, $22 billion is in the Federal-aid Highways account and
$18 billion is in the Federal Transit Administration’s Formula Grants account. The unobligated balances in these and other
surface transportation accounts are not cash balances. Rather, they are balances of contract authority, which is authority to
obligate the Federal government to eventually pay cash derived from either the gas taxes collected or taxpayer dollars from the
general fund of the Treasury. A primary reason for the level of unobligated balances is that the vast majority of the spending
for the Trust Fund accounts is contract authority capped by annual or multi-year obligation limitations. These limitations have
typically been imposed by the appropriations committees and serve to limit the amount of obligations that can be incurred in
either a single or multiple years. In prior years, the annual Federal Aid Highways obligation limitation has been set lower than
the annual contract authority level (resulting in balances of contract authority in excess of the obligation limitation), while the
Federal Transit Administration levels have been set to equal the contract authority level and unobligated transit limitation
carries forward exempt from the current year limitation. Both these dynamics result in higher than expected unobligated
balances, for both Federal-aid Highways and the Transit Formula grants. In addition to the surface transportation program
balances, there is $2 billion in unobligated balances in the Federal Aviation Administration (FAA) facilities and equipment
account that are due to the time required to develop and build capital projects for FAA infrastructure.

$193 billion is in the International Assistance Program’s Foreign Military Sales Trust Fund;
$11 billion is in the Department of the Interior’s Abandoned Mine Reclamation Fund;
$6 billion is in the Department of Justice’s United States Victims of State Sponsored Terrorism Fund;
$4 billion is in the Environmental Protection Agency’s Hazardous Substance Superfund;
$2 billion is in the Department of Health and Human Service’s Child Enrollment Contingency Fund;
$2 billion is in the Department of Homeland Security’s Immigration Examinations Fee;
$2 billion is in the Department of the Interior’s Permanent Operating Funds;
$2 billion is in the Department of Justice’s Assets Forfeiture Fund;
$2 billion is in the Department of State’s Consular and Border Security Programs;
$2 billion in the Corps of Engineers – Civil Works’ Rivers and Harbors Contributed Funds;
$2 billion is in the Bureau of Consumer Financial Protection’s Consumer Financial Civil Penalty Fund;
$1 billion is in the Judicial Branch’s Judicial Officers’ Retirement Fund;
$1 billion is in the Department of Defense – Military Programs’ Allied Contributions and Cooperation Account;
$1 billion is in the Department of Energy’s Construction, Rehabilitation, Operation and Maintenance, Western Area Power
Administration
$1 billion is in the Department of the Interior’s National Parks and Public Land Legacy Restoration Fund; and
$1 billion is in the Department of the Treasury’s Gulf Coast Restoration Trust Fund.

IV. PREFUNDING OF MAJOR APPROPRIATED ENTITLEMENTS. This category accounts for $54 billion of the total
estimated unobligated balances to be carried forward to 2024. Appropriations for these programs are based on estimates of demand.
Congress then frequently appropriates a small cushion of funding above estimated demand to eliminate the need for agencies to ask
for supplemental appropriations during the year when actual program need exceeds the estimated demand. This $54 billion of
unobligated balances is comprised of:
a.
b.
c.
d.

$25 billion for the Department of Agriculture’s Supplemental Nutrition Assistance Program and Child Nutrition Programs;
$24 billion for the Department of Veterans Affairs’ Compensation and Pensions, and Readjustment Benefits Programs;
$4 billion for the Social Security Administration’s Supplemental Security Income Program; and
$1 billion for the Department of Labor’s Special Benefits Program.

V. PROGRAMS WITH LONG LEAD TIMES TO OUTLAY. This category accounts for $200 billion of the total estimated
unobligated balances to be carried forward to 2024. These balances result from a fundamental budget principle that each Congress
should fund the full cost of projects that it authorizes agencies to enter into. Because construction, major procurement, and research
and development projects can take years to complete, the full-funding requirement means that agencies will hold unobligated balances
to cover obligations incurred over the life of the project. The alternative – providing partial funding to cover only work performed
during each fiscal year – would lead to procurement inefficiencies and force future Congresses to pay for the sunk costs incurred by
past Congresses.
VI. All OTHER PROGRAMS. This category accounts for the remaining $600 billion in estimated unobligated balances to be
carried over to 2024. Table 9 groups these amounts into Defense and Non-defense functions.
ADDITIONAL DETAILS.—An Excel file available at www.budget.gov provides a detailed list of balances by account in each
category.
