                   22.  TRUST FUNDS AND FEDERAL FUNDS

  The budget consists of two major groups of funds: Federal funds and 
trust funds. This section presents summary information about the 
transactions of each of these two fund groups. Information is provided 
about the income and outgo of the major trust funds and a number of 
Federal funds that are financed by earmarked collections in a manner 
similar to trust funds.

                           Federal Funds Group

  The Federal funds group comprises the larger part of the budget. It 
includes all transactions not classified by law as being in trust funds.
  The main financing component of the Federal funds group is the general 
fund, which is used to carry out the general purposes of Government 
rather than being restricted by law to a specific program. It consists 
of all collections not earmarked by law to finance other funds, 
including virtually all income taxes and many excise taxes, and all 
expenditures financed by these collections and by Treasury borrowing.

--------------------------------------------------------------------------------------------------------------------------------------------------------
Note: Receipts include governmental, interfund, and proprietary receipts. They exclude intrafund receipts, which are offset against intrafund payments
  so that cash income and cash outgo of the fund group are not overstated.

  The Federal funds group also includes special funds and revolving 
funds, which earmark collections for spending on specific purposes. 
Where the law requires that Federal fund collections from a specified 
source be earmarked to finance a particular program, such as a portion 
of the Outer Continental Shelf mineral leasing receipts deposited into 
the Land and Water Conservation Fund, the collections and associated 
disbursements are recorded in special fund receipt and expenditure 
accounts. The majority of special fund collections are derived from the 
Government's power to impose taxes, fines, and other compulsory 
payments. They must be appropriated before they can be obligated and 
spent. However, significant amounts of collections credited to special 
funds are derived from business-like activity, such as the receipts from 
Outer Continental Shelf mineral leasing.
  Revolving funds conduct continuing cycles of business-like activity. 
They charge for the sale of products or services and use the proceeds to 
finance their spending. Instead of being deposited in receipt accounts, 
their

[[Page 342]]

proceeds are recorded in the revolving funds, which are expenditure 
accounts. These collections generally are available automatically for 
obligation and making payments. Outlays for revolving funds are reported 
net of offsetting collections. There are two classes of revolving funds. 
Public enterprise funds, such as the Postal Service Fund, conduct 
business-like operations mainly with the public. Intragovernmental 
funds, such as the Federal Buildings Fund, conduct business-like 
operations mainly within and between Government agencies.

                            Trust Funds Group

  The trust funds group consists of funds that are designated by law as 
trust funds. Like special funds and revolving funds, they earmark 
collections for spending on specific purposes. Many of the larger trust 
funds finance social insurance payments for individuals, such as Social 
Security, Medicare, and unemployment compensation. Other major trust 
funds finance military and Federal civilian employees' retirement 
benefits, highway and transit construction, and airport and airway 
development. There are a few trust revolving funds that are credited 
with collections earmarked by law to carry out a cycle of business-type 
operations. Trust funds also include a few small funds established to 
carry out the terms of a conditional gift or bequest.
  There is no substantive difference between trust funds and special 
funds or between revolving funds and trust revolving funds. Whether a 
particular fund is designated in law as a trust fund is, in many cases, 
arbitrary. For example, the National Service Life Insurance Fund is a 
trust fund, but the Servicemen's Group Life Insurance Fund is a Federal 
fund, even though both are financed by earmarked fees paid by veterans 
and both provide life insurance payments to veterans' beneficiaries. \1\
---------------------------------------------------------------------------
  \1\ Another example is the Violent Crime Reduction Trust Fund, 
established pursuant to the Violent Crime Control and Law Enforcement 
Act of 1994. Because the Fund is substantively a means of accounting for 
general fund appropriations, and does not have any dedicated receipts, 
it is classified as a Federal fund rather than a trust fund, 
notwithstanding the presence of the words ``Trust Fund'' in its official 
name.
---------------------------------------------------------------------------
  The Federal budget meaning of the term ``trust'' differs significantly 
from the private sector usage. The beneficiary of a private trust owns 
the trust's income and often its assets. A custodian manages the assets 
on behalf of the beneficiary according to the stipulations of the trust, 
which he or she cannot change unilaterally. In contrast, the Federal 
Government owns the assets and earnings of most Federal trust funds, and 
it can unilaterally raise or lower future trust fund collections and 
payments, or change the purpose for which the collections are used, by 
changing existing law. Only a few small Federal trust funds are managed 
pursuant to a trust agreement where the Government is the trustee, and 
the Government generally owns them and has some ability to determine the 
amount deposited into or paid out of these funds. Other amounts are held 
in deposit funds by the Government as a custodian on behalf of some 
entity outside the Government. The Government makes no decisions about 
the amount of these deposits or how they are spent. Therefore, these 
funds are considered to be non-budgetary instead of Federal trust funds 
and are excluded from the Federal budget.
  A trust fund must use its income for the purposes designated by law. 
Some, such as the Federal Employees Health Benefits fund, spend their 
income almost as quickly as it is collected. Others, such as the Social 
Security and the Federal civilian employees retirement trust funds, 
currently spend considerably less than they collect each year. A surplus 
of income over outgo adds to the trust fund's balance, which is 
available to finance future expenditures. The balances are generally 
invested, by law, in Treasury securities. \2\
---------------------------------------------------------------------------
  \2\ The relationships between Treasury securities held by trust funds 
(and by other Government accounts), debt held the public, and gross 
Federal debt are discussed in Chapter 16 of this volume, ``Federal 
Borrowing and Debt.''
---------------------------------------------------------------------------
  A trust fund normally consists of one or more receipt accounts (to 
record income) and an expenditure account (to record outgo). However, a 
few trust funds, such as the Veterans Special Life Insurance fund, are 
established by law as revolving funds. These funds are similar to 
revolving funds in the Federal funds group, in that they may consist of 
a single account to record both income and outgo. They conduct a cycle 
of business-type operations; offsetting collections are credited to the 
funds (which are expenditure accounts); and their outlays are displayed 
net of the offsetting collections.

                     Income and Outgo by Fund Group

  Table 22-1 shows income, outgo, and surplus or deficit by fund group 
and adds them together (and removes double-counting) to derive the total 
unified budget receipts, outlays, and surplus or deficit. The estimates 
assume enactment of the President's budget proposals. Income consists 
mostly of receipts (derived from governmental activity--primarily 
income, payroll, and excise taxes--and gifts). It also consists of 
offsetting receipts, which include proprietary receipts (derived from 
business-like transactions with the public) and interfund collections 
(receipts by one fund of payments from a fund in the other fund group) 
that are deposited in receipt accounts. Outgo consists of payments made 
to the public or to a fund in the other fund group.

* $50 million or less.

  Two types of transactions are treated specially in the table. First, 
income and outgo for a fund group exclude transactions between funds 
within the same fund group. \3\ These intrafund transactions constitute 
outgo and income for the individual funds that make and collect the 
payments. However, because the totals for each fund group measure its 
transactions with the public and the other fund group, intrafund 
transactions must be subtracted from the sum of the income and outgo of 
all individual funds within the fund group to calculate the consolidated 
income and outgo for that fund group as a whole. Second, income excludes 
the

[[Page 343]]

offsetting collections, which are offset against outgo in revolving fund 
expenditure accounts instead of being deposited in receipt accounts.\4\ 
It would be conceptually appropriate to classify these collections as 
income, but at present the data are not tabulated centrally for both 
fund groups. Consequently, they are offset against outgo in Table 22-1 
and are not shown separately.
---------------------------------------------------------------------------
  \3\ For example, the railroad retirement trust funds pay the 
equivalent of social security benefits to railroad retirees, in addition 
to the regular railroad pension. These benefits are financed by a 
payment from the Federal Old-Age and Survivors Insurance trust fund to 
the railroad retirement trust funds. The payment and collection are both 
deducted so that total trust fund income and outgo measure disbursements 
to the public and to Federal funds.
  \4\ For example, postage stamp fees are deposited as offsetting 
collections in the Postal Service fund. As a result, the Fund's outgo is 
disbursements net of collections.
---------------------------------------------------------------------------
  Some funds in the Federal funds group and some trust funds are 
authorized to borrow from the general fund of the Treasury. \5\ Borrowed 
funds are not recorded as receipts of the fund or included in the income 
of the fund. The borrowed funds finance outlays by the fund in excess of 
available receipts. Subsequently, fund receipts are transferred from the 
fund to the general fund in repayment of the borrowing. The repayment is 
not recorded as an outlay of the fund or included in fund outgo.
---------------------------------------------------------------------------
  \5\ For example, the Bonneville Power Administration Fund, a revolving 
fund in the Department of Energy, is authorized to borrow from the 
general fund, and the Black Lung Disability Trust Fund in the Department 
of Labor is authorized to receive appropriations of repayable advances 
from the general fund (a form of borrowing).
---------------------------------------------------------------------------
  Some income in both Federal funds and trust funds consists of 
offsetting receipts. In contrast, for most budget purposes, offsetting 
receipts are excluded from receipts figures and subtracted from gross 
outlays. There are two reasons for the normal treatment:
    Business-like or market-oriented activities with the public: 
          The collections from such activities are deducted from gross 
          outlays, rather than added to receipts, in order to produce 
          budget totals for receipts and outlays that represent 
          governmental rather than market activity.
    Intragovernmental transactions: Collections by one 
          Government account from another are deducted from gross 
          outlays, rather than added to receipts, so that the budget 
          totals measure the transactions of the Government with the 
          public.
  Because the income for Federal funds and for trust funds recorded in 
Table 22-1 includes offsetting receipts, those offsetting receipts must 
be deducted from the two fund groups' combined gross income in order to 
reconcile to total (net) unified budget receipts. Similarly, because the 
outgo for Federal funds and for trust funds in Table 22-1 consists of 
outlays gross of offsetting receipts, the amount of the offsetting 
receipts must be deducted from the sum of the Federal funds' and the 
trust funds' gross outgo in order to reconcile to total (net) unified 
budget outlays. Table 22-3 reconciles, for fiscal year 2005, the gross 
total of all trust fund and Federal fund receipts with the net total of 
the

[[Page 344]]

Federal fund group's and the trust fund group's cash income (as shown in 
Table 22-1), and with the unified budget's receipt total.

               Income, Outgo, and Balances of Trust Funds

  Table 22-2 shows, for the trust funds group as a whole, the funds' 
balance at the start of each year, income and outgo during the year, and 
the end of year balance. Income and outgo are divided between 
transactions with the public and transactions with Federal funds. 
Receipts from Federal funds are divided between interest and other 
interfund receipts.
  The definition of income and outgo in this table differs from those in 
Table 22-1 in one important way. Trust fund collections that are offset 
against outgo (as offsetting collections) within expenditure accounts 
instead of being deposited in separate receipt accounts are classified 
as income in this table but not in Table 22-1. This classification is 
consistent with the definitions of income and outgo for trust funds used 
elsewhere in the budget. It has the effect of increasing both income and 
outgo by the amount of the offsetting collections. The difference was 
approximately $46 billion in 2005. Table 22-2, therefore, provides a 
more complete summary of trust fund income and outgo.
  The trust funds group is expected to have large and growing surpluses 
over the projection period. As a consequence, trust fund balances are 
estimated to grow substantially, as they have over the past two decades. 
The size of the anticipated balances is unprecedented, and it results 
mainly from relatively recent changes in the way some trust funds are 
financed.
  Primarily because of these changes, but also because of the impact of 
real growth and inflation, trust fund balances increased tenfold from 
1982 to 2000, from $205 billion to $2.1 trillion. The balances are 
estimated to more than double again by the year 2011, rising to $4.9 
trillion. \6\ Almost all of these balances are invested in Treasury 
securities and earn interest. Therefore, they represent the value, in 
current dollars, of taxes and user fees that have been paid in advance 
for future benefits and services.
---------------------------------------------------------------------------
  \6\ The trust fund balances shown here reflect the Administration's 
proposal to add Personal Retirement Accounts (PRAs) as part of a reform 
to return the social security program to solvency. Because the PRAs 
would be privately owned, their balances would not be included in the 
budget or in trust fund balances. Diverting a portion of payroll taxes 
into PRAs will slow the growth of aggregate trust fund balances in the 
short term, but this effect will ultimately be offset by lower social 
security benefit payments to those who opt for PRAs, and thus have a 
neutral effect on the growth of fund balances in the long run.
---------------------------------------------------------------------------
  Until the 1980s, most trust funds operated on a pay-as-you-go basis. 
Taxes and user fees were set at levels high enough to finance program 
expenditures and administrative expenses, and to maintain prudent 
reserves, generally defined as being equal to one year's expenditures. 
As a result, trust fund balances tended to grow at about the same rate 
as their annual expenditures.
  Pay-as-you-go financing was replaced in the 1980s by full or partial 
advance funding for some of the larger

trust funds. In order to partially prefund the social security benefits 
of the ``baby-boomers'', the Social Security Amendments of 1983 raised 
payroll taxes above the levels necessary to finance current 
expenditures. In 1984 a new system was set up to finance military 
retirement benefits on a full accrual basis. In 1986 full accrual 
funding of retirement benefits was mandated for Federal civilian 
employees hired after December 31, 1983. The latter two changes require 
Federal agencies and their employees to make annual payments to the 
Federal employees' retirement trust funds in an amount equal to the 
retirement benefits earned by employees. Since many years will pass 
between the time when benefits are earned and when they are paid, the 
trust funds will accumulate substantial balances over time.
  These balances are available to finance future benefit payments and 
other trust fund expenditures--but only in a bookkeeping sense. These 
funds are not set up to be pension funds, like the funds of private 
pension plans. The holdings of the trust funds are not assets of the 
Government as a whole that can be drawn down in the future to fund 
benefits. Instead, they are claims on the Treasury. When trust fund 
holdings are redeemed to pay benefits, Treasury will have to finance the 
expenditure in the same way as any other Federal expenditure: out of 
current receipts, by borrowing from the public, or by reducing benefits 
or other expenditures. The existence of large trust fund balances, 
therefore, does not, by itself, increase the Government's ability to pay 
benefits.
  From an economic standpoint, the Government is able to prefund 
benefits only by increasing saving and investment in the economy as a 
whole. This can be fully accomplished only by simultaneously running 
trust fund surpluses equal to the actuarial present value of the 
accumulating benefits and not allowing the Federal fund deficit to 
increase, so that the trust fund surplus reduces a unified budget 
deficit or increases a unified budget surplus. This would reduce Federal 
borrowing by the amount of the trust funds surplus and increase the 
amount of national saving available to finance investment. Greater 
investment would increase future incomes and wealth, which would provide 
more real economic resources to support the benefits.
  Table 22-4, on the CD-ROM included with this volume, shows estimates 
of income, outgo, and balances for 2004 through 2011 for the major trust 
funds. With the exception of transactions between trust funds, the data 
for the individual trust funds are conceptually the same as the data in 
Table 22-2 for the trust funds group. As explained previously, 
transactions between trust funds are shown as outgo of the fund that 
makes the payment and as income of the fund that collects it in the data 
for an individual trust fund, but the collections are offset against 
outgo in the data for the trust fund group. Additional information for 
these and other trust funds can be found in the Status of Funds tables 
in the Budget Appendix.
  Table 22-5 (also on the CD-ROM) shows income, outgo, and balances of 
four existing Federal funds--three revolving funds and one special fund. 
It also shows a recently-established special fund of the same general 
type: a fund for military retirees' health benefits. All these funds are 
similar to trust funds in that they are financed by earmarked receipts, 
the excess of income over outgo is invested, the interest earnings add 
to balances, and the balances remain available to finance future 
expenditures. The table is illustrative of the Federal funds group, 
which includes many other revolving funds and special funds in addition 
to the ones shown.
