Why GAO Did This Study: 

GAO is required to audit the consolidated financial statements of the 
U.S. government. Because of the significance of the federal debt held 
by the public to the government-wide financial statements, GAO audits 
BPD’s Schedules of Federal Debt annually to determine whether, in all 
material respects, (1) the schedules are reliable and (2) BPD 
management maintained effective internal control over financial 
reporting relevant to the Schedule of Federal Debt. Further, GAO tests 
compliance with selected provisions of laws related to the Schedule of 
Federal Debt. 

Federal debt managed by BPD consists of Treasury securities held by 
the public and by certain federal government accounts, referred to as 
intragovernmental debt holdings. Debt held by the public essentially 
represents the amount the federal government has borrowed to finance 
cumulative cash deficits. Intragovernmental debt holdings represent 
balances of Treasury securities held by federal government accounts—-
primarily federal trust funds such as Social Security and Medicare—-
that typically have an obligation to invest their excess annual 
receipts (including interest earnings) over disbursements in federal 
securities. 

In commenting on a draft of this report, BPD’s Commissioner concurred 
with our conclusions. 

What GAO Found: 

In GAO’s opinion, the Bureau of the Public Debt’s (BPD) Schedules of 
Federal Debt for fiscal years 2012 and 2011 were fairly presented in 
all material respects, and BPD maintained effective internal control 
over financial reporting relevant to the Schedule of Federal Debt as 
of September 30, 2012. GAO’s tests of BPD’s compliance in fiscal year 
2012 with selected provisions of laws related to the Schedule of 
Federal Debt disclosed no instances of noncompliance. 

As of September 30, 2012 and 2011, federal debt managed by BPD totaled 
$16,059 billion and $14,781 billion, respectively. GAO has audited the 
Schedule of Federal Debt since fiscal year 1997. Over this period, 
total federal debt has increased by 197 percent. Also during this 
period, the statutory debt limit was raised 13 times, from $5,950 
billion to its current level of $16,394 billion.

[End of figure] 

During fiscal year 2012, delays in raising the statutory debt limit 
occurred prior to the January 2012 increase in the limit, with the 
Department of the Treasury (Treasury) deviating from its normal debt 
management operations and taking certain extraordinary actions within 
its legal authorities to avoid exceeding the debt limit. As part of 
the process established by the Budget Control Act of 2011, the 
statutory debt limit was increased by $1,200 billion effective after 
close of business on January 27, 2012. In July 2012, GAO reported on 
extraordinary actions Treasury took during 2011 and January 2012 to 
manage federal debt when delays in raising the debt limit occurred and 
the effect of delayed increases on Treasury borrowing costs. As with 
its February 2011 report, GAO also noted in its July 2012 report that 
Congress should consider ways to better link decisions about the debt 
limit with decisions about spending and revenue to avoid potential 
disruptions to the Treasury market and to help inform the fiscal 
policy debate in a timely way.

November 8, 2012: 

The Honorable Timothy F. Geithner:
Secretary of the Treasury: 

Dear Mr. Secretary: 

The accompanying auditor's report presents the results of our audits 
of the Schedules of Federal Debt Managed by the Bureau of the Public 
Debt for the fiscal years ended September 30, 2012 and 2011. The 
Schedules of Federal Debt present the beginning balances, increases 
and decreases, and ending balances for (1) Federal Debt Held by the 
Public and Intragovernmental Debt Holdings, (2) the related Accrued 
Interest Payables, and (3) the related Net Unamortized Premiums and 
Discounts managed by the Department of the Treasury's (Treasury) 
Bureau of the Public Debt (BPD). 

The auditor's report contains our (1) unqualified opinions on the 
Schedules of Federal Debt for the fiscal years ended September 30, 
2012 and 2011; (2) opinion that BPD maintained, in all material 
respects, effective internal control over financial reporting relevant 
to the Schedule of Federal Debt as of September 30, 2012; and (3) 
conclusion that our tests of BPD's compliance with selected provisions 
of laws related to the Schedule of Federal Debt disclosed no instances 
of reportable noncompliance. 

As of September 30, 2012 and 2011, federal debt managed by BPD totaled 
$16,059 billion and $14,781 billion, respectively, primarily for 
borrowings to fund the federal government's operations. As shown on 
the Schedules of Federal Debt, these balances consisted of 
approximately (1) $11,270 billion as of September 30, 2012, and 
$10,127 billion as of September 30, 2011, of debt held by the public 
and (2) $4,789 billion as of September 30, 2012, and $4,654 billion as 
of September 30, 2011, of intragovernmental debt holdings. 

Debt held by the public essentially represents the amount the federal 
government has borrowed from the public to finance cumulative cash 
deficits. When a cash surplus occurs, the annual excess funds can be 
used to reduce debt held by the public. In other words, annual cash 
deficits or surpluses generally approximate the annual net change in 
the amount of federal government borrowing from the public. Debt held 
by the public represents federal debt issued by Treasury and held by 
investors outside of the federal government, including individuals, 
corporations, state or local governments, the Federal Reserve, and 
foreign governments. The majority of debt held by the public consists 
of marketable Treasury securities, such as bills, notes, bonds, and 
Treasury Inflation-Protected Securities that are sold through auctions 
and can be resold by whoever owns them. Treasury also issues a smaller 
amount of nonmarketable securities, such as savings securities and 
State and Local Government Series securities. 

As we have noted in previous years, Treasury reporting shows that 
foreign ownership of Treasury securities represents a significant 
portion of debt held by the public. As of June 30, 2012, the reported 
amount of Treasury securities held by foreign and international 
investors represented an estimated 48 percent of debt held by the 
public. This percentage is slightly higher than the 46 percent as of 
June 30, 2011, and remains considerably higher than the estimated 30 
percent of debt held by the public as of June 30, 2001. Treasury 
estimates that the amount of Treasury securities held by foreign and 
international investors has increased from $983 billion as of June 30, 
2001, to $5,311 billion as of June 30, 2012--an increase of $4,328 
billion. Estimates of foreign ownership of Treasury securities are 
derived from information reported under the Treasury International 
Capital reporting system not from the financial system used to prepare 
the Schedule of Federal Debt. These estimates are not reported on the 
Schedules of Federal Debt and as such we do not audit these amounts. 
[Footnote 1] 

Intragovernmental debt holdings represent federal debt owed by 
Treasury to federal government accounts--primarily federal trust funds 
such as Social Security and Medicare--that typically have an 
obligation to invest their excess annual receipts (including interest 
earnings) over disbursements in federal securities. Most federal 
government accounts invest in special nonmarketable Treasury 
securities that represent legal obligations of the Treasury and are 
guaranteed for principal and interest by the full faith and credit of 
the U.S. government. The federal government uses the federal 
government accounts' invested cash surpluses to assist in funding 
other federal government operations. Unlike debt held by the public, 
intragovernmental debt holdings are not shown as balances on the 
federal government's consolidated financial statements because they 
represent loans from one part of the federal government to another. 
Under U.S. generally accepted accounting principles, when the federal 
government's financial statements are consolidated, those offsetting 
balances are eliminated. 

Debt held by the public and intragovernmental debt holdings are very 
different. Debt held by the public represents a burden on today's 
economy as borrowing from the public absorbs resources available for 
private investment and may put upward pressure on interest rates. In 
addition, interest on debt held by the public is paid in cash and 
represents a burden on current taxpayers. Moreover, the interest paid 
on this debt may reduce budget flexibility because, unlike most of the 
budget, it cannot be controlled directly. In contrast, 
intragovernmental debt holdings typically do not require cash payments 
from the current budget or represent a burden on the current economy. 
In addition, from the perspective of the budget as a whole, Treasury's 
interest payments to federal government accounts are entirely offset 
by the income received by such accounts. However, this 
intragovernmental debt and related interest reflects a burden on 
taxpayers and the economy in the future. Specifically, when federal 
government accounts redeem Treasury securities to obtain cash to fund 
expenditures, Treasury usually borrows from the public to finance 
these redemptions.[Footnote 2] 

We have audited the Schedule of Federal Debt since fiscal year 1997. 
Over this period, total federal debt has increased by 197 percent. 
Also during this period, the statutory debt limit was raised 13 times, 
from $5,950 billion to $16,394 billion. During the last 4 fiscal 
years, total federal debt has increased by $6,048 billion, or 60 
percent, from $10,011 billion as of September 30, 2008, to $16,059 
billion as of September 30, 2012. The rapid growth in federal debt 
during this period presented debt management challenges for Treasury. 
[Footnote 3] The economic downturn along with the federal government's 
response to it contributed to this rapid buildup in federal debt held 
by the public. As a result, the increases to total federal debt over 
the past 4 fiscal years represent the largest dollar increases over a 
4-year period in history. During fiscal year 2012 alone, total federal 
debt increased by $1,278 billion. Of the fiscal year 2012 increase, 
$1,143 billion was from the increase in debt held by the public and 
$135 billion was from the increase in intragovernmental debt holdings. 
Notably, the statutory debt limit was raised on seven different 
occasions during the last 4 fiscal years, increasing by about 54 
percent, from $10,615 billion to its current level of $16,394 billion. 
As of September 30, 2012, debt subject to the limit totaled $16,027 
billion.[Footnote 4] 

During fiscal year 2012, Treasury faced an additional challenge of 
managing federal debt close to the statutory debt limit. Delays in 
raising the statutory debt limit occurred prior to the January 2012 
increase in the limit, with Treasury deviating from its normal debt 
management operations and taking certain extraordinary actions within 
its legal authorities from January 4, 2012, through January 27, 2012, 
to avoid exceeding the debt limit. These actions included suspending 
investments to the Government Securities Investment Fund of the 
Federal Employees' Retirement System (G-Fund)[Footnote 5] and the 
Exchange Stabilization Fund (ESF).[Footnote 6] As part of the process 
established by the Budget Control Act of 2011 (BCA), the statutory 
debt limit was increased by $1,200 billion to its current level of 
$16,394 billion effective after close of business on January 27, 2012. 
[Footnote 7] Subsequent to the January 2012 increase in the statutory 
debt limit, Treasury fully restored the G-Fund to the position it 
would have been in had the suspensions of debt not occurred. Treasury 
also invested the uninvested principal for January 2012 to the ESF. 
However, Treasury did not restore interest losses to the ESF because 
it lacks legislative authority to do so. Additionally, as a result of 
extraordinary actions taken in fiscal year 2011 to manage federal debt 
within the statutory debt limit, Treasury restored interest losses to 
the Civil Service Retirement and Disability Fund[Footnote 8] and the 
Postal Service Retiree Health Benefits Fund[Footnote 9] on December 
30, 2011, in accordance with the legal authorities provided to the 
Secretary of the Treasury. In July 2012, we reported on the 
extraordinary actions Treasury took during 2011 and January 2012 to 
manage federal debt when delays in raising the debt limit occurred and 
the effect of delayed increases on Treasury borrowing costs. As with 
our February 2011 report, we also noted in our July 2012 report that 
Congress should consider ways to better link decisions about the debt 
limit with decisions about spending and revenue to avoid potential 
disruptions to the Treasury market and to help inform the fiscal 
policy debate in a timely way.[Footnote 10] 

Federal financing needs remain high, in part due to the persistent 
effects of the economic downturn and its impact on the federal 
deficit. The reported federal deficit for fiscal year 2012 was $1,089 
billion, down from the fiscal year 2011 reported federal deficit of 
$1,297 billion. Correspondingly, debt held by the public increased 
from roughly 68 percent of gross domestic product (GDP) at the end of 
fiscal year 2011 to roughly 73 percent at the end of fiscal year 2012. 
The pace at which federal debt held by the public increases over the 
next several years depends largely on whether current laws, such as 
spending limits pursuant to the BCA[Footnote 11] and the expiration of 
certain tax cuts enacted in 2001 and 2003, take effect. Over the 
longer term, debt held by the public as a share of GDP is expected to 
grow as a result of the structural imbalance between revenue and 
spending driven by rising health care costs and demographics. 
Increasing numbers of baby-boom generation members are becoming 
eligible for Social Security retirement benefits and for Medicare. In 
addition, although health care spending growth recently slowed, it has 
been growing faster than the overall economy and is expected to 
continue to grow at an increased rate as more members of the baby-boom 
generation retire and become eligible for federal health programs. The 
aging of the population and rising health care costs will continue to 
put upward pressure on spending and, absent action to address the 
growing imbalance between spending and revenue, the federal government 
faces an unsustainable growth in debt.[Footnote 12]

committees, the Commissioner of the Bureau of the Public Debt, the 
Inspector General of the Department of the Treasury, the Acting 
Director of the Office of Management and Budget, and other agency

Independent Auditor's Report: 

To the Commissioner of the Bureau of the Public Debt: 

In connection with fulfilling our requirement to audit the 
consolidated financial statements of the U.S. government, we have 
audited the Schedules of Federal Debt Managed by the Bureau of the 
Public Debt (BPD) because of the significance of the federal debt to 
the federal government's consolidated financial statements.[Footnote 
13] 

This auditor's report presents the results of our audits of the 
Schedules of Federal Debt Managed by BPD for the fiscal years ended 
September 30, 2012 and 2011. The Schedules of Federal Debt present the 
beginning balances, increases and decreases, and ending balances for 
(1) Federal Debt Held by the Public and Intragovernmental Debt 
Holdings, (2) the related Accrued Interest Payables, and (3) the 
related Net Unamortized Premiums and Discounts managed by the 
Department of the Treasury's (Treasury) BPD.[Footnote 14] 

In our audits of the Schedules of Federal Debt Managed by BPD for the 
fiscal years ended September 30, 2012 and 2011, we found: 

* the Schedules of Federal Debt are presented fairly, in all material 
respects, in conformity with U.S. generally accepted accounting 
principles; 

* BPD maintained, in all material respects, effective internal control 
over financial reporting relevant to the Schedule of Federal Debt as 
of September 30, 2012; and: 

* no reportable noncompliance in fiscal year 2012 with selected 
provisions of laws we tested related to the Schedule of Federal Debt. 

The following sections discuss in more detail (1) these conclusions; 
(2) other information included with the Schedules of Federal Debt; (3) 
our audit objectives, scope, and methodology; and (4) BPD's comments 
on a draft of this report. 

Opinion on the Schedules of Federal Debt: 

The Schedules of Federal Debt including the accompanying notes present 
fairly, in all material respects, in conformity with U.S. generally 
accepted accounting principles, the balances as of September 30, 2012, 
2011, and 2010 for Federal Debt Managed by BPD; the related Accrued 
Interest Payables and Net Unamortized Premiums and Discounts; and the 
related increases and decreases for the fiscal years ended September 
30, 2012 and 2011. 

Opinion on Internal Control: 

BPD maintained, in all material respects, effective internal control 
over financial reporting relevant to the Schedule of Federal Debt as 
of September 30, 2012, that provided reasonable assurance that 
misstatements, losses, or noncompliance material in relation to the 
Schedule of Federal Debt would be prevented or detected and corrected 
on a timely basis. Our opinion on internal control is based on 
criteria established under 31 U.S.C. § 3512(c), (d), commonly known as 
the Federal Managers' Financial Integrity Act (FMFIA). 

We identified deficiencies in BPD's system of internal control that we 
consider not to be material weaknesses or significant deficiencies. 
[Footnote 15] We have communicated these matters to management and, 
where appropriate, will report on them separately. In late fiscal year 
2011, Treasury began consolidating the data centers and related 
operations of BPD and Treasury's Financial Management Service. Given 
the significant role that certain information systems have in managing 
federal debt, it will be important that BPD management assesses risks 
associated with the consolidation and ensures that internal control 
over the information systems in these data centers is effectively 
designed and implemented. 

Compliance with Selected Provisions of Laws: 

Our tests of BPD's compliance in fiscal year 2012 with selected 
provisions of laws related to the Schedule of Federal Debt disclosed 
no instances of noncompliance that would be reportable under U.S. 
generally accepted government auditing standards. The objective of our 
audit was not to provide an opinion on overall compliance with laws 
and regulations. Accordingly, we do not express such an opinion. 

Other Information: 

BPD's other information, which consists of the Overview on Federal 
Debt Managed by the Bureau of the Public Debt, contains a wide range 
of information, some of which is not directly related to the Schedules 
of Federal Debt. This information is presented for purposes of 
additional analysis and is not a required part of the Schedules of 
Federal Debt. Our audit was conducted for the purpose of forming an 
opinion on the Schedules of Federal Debt. We did not audit and do not 
express an opinion or provide any assurance on the other information. 

Objectives, Scope, and Methodology: 

BPD management is responsible for (1) preparing the Schedules of 
Federal Debt in conformity with U.S. generally accepted accounting 
principles; (2) preparing and presenting other information included 
with the audited Schedules of Federal Debt and auditor's report, and 
ensuring the consistency of that information with the audited 
Schedules of Federal Debt; (3) establishing and maintaining effective 
internal control over financial reporting, and evaluating its 
effectiveness; and (4) complying with applicable laws and regulations. 
BPD management evaluated the effectiveness of BPD's internal control 
over financial reporting relevant to the Schedule of Federal Debt as 
of September 30, 2012, based on the criteria established under FMFIA. 
BPD management's assertion based on its evaluation is included in 
appendix I. 

We are responsible for planning and performing the audit to obtain 
reasonable assurance and provide our opinion about whether (1) the 
Schedules of Federal Debt are presented fairly, in all material 
respects, in conformity with U.S. generally accepted accounting 
principles and (2) BPD management maintained, in all material 
respects, effective internal control over financial reporting relevant 
to the Schedule of Federal Debt as of September 30, 2012. We are also 
responsible for (1) testing compliance with selected provisions of 
laws and regulations that have a direct and material effect on the 
Schedule of Federal Debt and (2) applying certain limited procedures 
to the other information included with the Schedules of Federal Debt. 

In order to fulfill these responsibilities, we: 

* examined, on a test basis, evidence supporting the amounts and 
disclosures in the Schedules of Federal Debt; 

* assessed the accounting principles used and any significant 
estimates made by BPD management; 

* evaluated the overall presentation of the Schedules of Federal Debt; 

* obtained an understanding of BPD and its operations, including its 
internal control over financial reporting relevant to the Schedule of 
Federal Debt; 

* considered BPD's process for evaluating and reporting on internal 
control over financial reporting relevant to the Schedule of Federal 
Debt based on the criteria established under FMFIA; 

* assessed the risk of (1) material misstatement in the Schedule of 
Federal Debt and (2) material weaknesses in BPD's internal control 
over financial reporting relevant to the Schedule of Federal Debt; 

* evaluated the design and operating effectiveness of BPD's internal 
control over financial reporting relevant to the Schedule of Federal 
Debt based on the assessed risk; 

* tested BPD's internal control over financial reporting relevant to 
the Schedule of Federal Debt; 

* tested compliance in fiscal year 2012 with the (1) statutory debt 
limit (31 U.S.C. §§ 3101(b), as amended, and 3101A) and (2) suspension 
of investments from the Government Securities Investment Fund (G-Fund) 
(5 U.S.C. § 8438(g)); 

* read the other information included with the Schedules of Federal 
Debt in order to identify material inconsistencies, if any, with the 
audited Schedules of Federal Debt; and: 

* performed such other procedures as we considered necessary in the 
circumstances. 

Internal control over financial reporting relevant to the Schedule of 
Federal Debt is a process effected by those charged with governance, 
management, and other personnel, the objectives of which are to 
provide reasonable assurance that (1) transactions are properly 
recorded, processed, and summarized to permit the preparation of the 
Schedule of Federal Debt in conformity with U.S. generally accepted 
accounting principles and (2) transactions related to the Schedule of 
Federal Debt are executed in accordance with laws governing the use of 
budget authority and other laws and regulations that could have a 
direct and material effect on the Schedule of Federal Debt. 

We did not evaluate all internal controls relevant to operating 
objectives as broadly established under FMFIA, such as those controls 
relevant to preparing statistical reports and ensuring efficient 
operations. We limited our internal control testing to testing 
controls over financial reporting. Our internal control testing was 
for the purpose of expressing an opinion on the effectiveness of 
internal control over financial reporting and may not be sufficient 
for other purposes. Consequently, our audit may not identify all 
deficiencies in internal control over financial reporting that are 
less severe than a material weakness. Because of inherent limitations, 
internal control may not prevent or detect and correct misstatements 
due to error or fraud, losses, or noncompliance. We also caution that 
projecting any evaluation of effectiveness to future periods is 
subject to the risk that controls may become inadequate because of 
changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate. 

We did not test compliance with all laws and regulations applicable to 
BPD. We limited our tests of compliance to selected provisions of laws 
that have a direct and material effect on the Schedule of Federal Debt 
for the fiscal year ended September 30, 2012. We caution that 
noncompliance may occur and not be detected by these tests and that 
such testing may not be sufficient for other purposes. 

We performed our audit in accordance with U.S. generally accepted 
government auditing standards. We believe our audit provides a 
reasonable basis for our opinions and other conclusions.

Overview, Schedules, and Notes: 

Overview on Federal Debt Managed by the Bureau of the Public Debt: 

Gross Federal Debt Outstanding: 

Federal debt managed by the Bureau of the Public Debt (BPD) comprises 
debt held by the public and debt held by certain federal government 
accounts (under 31 U.S.C. § 3101), the latter of which is referred to 
as intragovemmental debt holdings. As of September 30, 2012 and 2011, 
outstanding gross federal debt managed by BPD totaled $16,059 billion 
and $14,781 billion, respectively.[Footnote 1] The increase in gross 
federal debt of $1,278 billion during fiscal year 2012 was due to an 
increase in gross intragovemmental debt holdings of $135 billion and 
an increase in gross debt held by the public of $1,143 billion. As 
Figure 1 illustrates, intragovenunental debt holdings and debt held by  
the public increased by $587 billion and $5,461 billion, respectively, 
from September 30, 2008 to September 30, 2012. The primly reason for 
the increases in intragovernmental debt holdings is the excess annual 
receipts (including interest earnings) over disbursements in the 
Federal Old-Age and Survivors Insurance Trust Fund, Civil Service 
Retirement and Disability Fund, Military Retirement Fund, and DOD 
Medicare-Eligible Retiree Health Care Fund. The increases in debt held 
by the public are due primarily to total federal spending exceeding 
total federal revenues. As of September 30, 2012, gross debt held by 
the public totaled $11,270 billion and gross intragovermnental debt 
holdings totaled $4,789 billion.

Interest Expense: 

Interest expense incurred during fiscal year 2012 consists of (1) 
interest accrued and paid on debt held by the public or credited to 
accounts holding intragovenunental debt during the fiscal year, (2) 
interest accrued during the fiscal year, but not yet paid on debt held 
by the public or credited to accounts holding intragovernmental debt, 
and (3) net amortization of premiums and discounts. The primary 
components of interest expense are interest paid on the debt held by 
the public and interest credited to federal government trust funds and 
other federal government accounts that hold Treasury securities. The 
interest paid on the debt held by the public affects the current 
spending of the federal government and represents the burden of 
servicing its debt (i.e., payments to outside creditors). Interest 
credited to federal government trust funds and other federal 
government accounts, on the other hand, does not result in an   
immediate outlay of the Federal Government because one part of the 
government pays the interest and another part receives it. However, 
this interest represents a claim on future budgetary resources and 
hence an obligation on future taxpayers. This interest, when 
reinvested by the trust funds and other federal government accounts, 
is included in the programs' excess funds not currently needed in 
operations, which are invested in federal securities. For fiscal year 
2012, interest expense incurred totaled $432 billion; this consisted 
of interest expense on debt held by the public of $245 billion, and 
$187 billion in interest incurred for intragovenunental debt holdings. 
As Figure 2 illustrates, due to the economic conditions, there was a 
significant increase in the demand for government backed securities 
during fiscal year 2009, which resulted in lower average interest 
rates and interest expense for that year. For example, the average 
interest rates on Treasury bills outstanding as of September 30, 2009 
and 2008 were 0.3 percent and 1.6 percent, respectively. Interest 
expense increased for fiscal years 2010 and 2011 due primarily to an   
increase in Treasury notes and bonds outstanding, which had higher 
average interest rates than Treasury bills. Interest expense decreased 
for fiscal year 2012 due primarily to a decrease in the average 
interest rates for Treasury notes, bonds, and Treasury Inflation-
Protected Securities (TIPS). Average interest rates on principal 
balances outstanding as of September 30, 2012 and 2011, are disclosed 
in the Notes to the Schedules of Federal Debt.

Debt Held by the Public: 

Debt held by the public primarily represents the amount the Federal 
Government has borrowed to finance cumulative cash deficits. During 
fiscal year 2012, Treasury used the existing suite of securities to 
meet the borrowing needs of the Federal Government while primarily 
increasing its offerings of Treasury notes over offerings of Treasury 
bills, Treasury bonds, or TIPS. As a result, Treasury notes increased 
by $708 billion; whereas, Treasury bills, bonds, and TIPS increased by 
$137 billion, $178 billion, and $102 billion, respectively, in fiscal 
year 2012. As of September 30, 2012 and 2011, gross debt held by the 
public totaled $11,270 billion and $10,127 billion, respectively (see 
Figure 1), an increase of $1,143 billion. This increase was primarily 
the result of borrowings needed to finance the governments fiscal year 
2012 deficit. As a result of the increase in outstanding gross debt 
held by the public primarily being in the form of longer term 
securities, the total dollar amount of activity for both borrowings 
and repayments of debt held by the public decreased for fiscal year 
2012.  

As of September 30, 2012, $10,730 billion, or 95 percent, of the 
securities that constitute debt held by the public were marketable, 
meaning that once the Federal Government issues them, they can be 
resold by whoever owns them Marketable debt is made up of Treasury 
bills, Treasury notes, Treasury bonds, and TIPS with maturity dates  
ranging from less than 1 year out to 30 years. Of the marketable 
securities currently held by the public as of September 30, 2012, 
$6,225 billion, or 58 percent, will mature within the next 4 years 
(see Figure 3). As of September 30, 2012 and 2011, notes and TIPS held 
by the public maturing within the next 10 years totaled $7,646 billion 
and $6,916 billion, respectively, an increase of $730 billion.

September 30, 2012: 

[Refer to PDF for image: stacked line graph] 

Figure indicates the fiscal year of maturity, 2011 through 2042, and 
amounts of marketable debt in the following categories: 
TIPS; 
Bonds; 
Notes; 
Bills. 

[End of figure] 

The Federal Government also issues to the public nonmarketable 
securities, which cannot be resold, and have maturity dates ranging 
from on demand out to 40 years. As of September 30, 2012, 
nonmarketable securities totaled $539 billion, or 5 percent of debt 
held by the public. As of that date. nonmarketable securities 
primarily consisted of savings securities totaling $184 billion, State 
and Local Government Series securities totaling $159 billion, and
Government Account Series securities totaling $163 billion. 
The Federal Reserve Banks (FRBs) act as fiscal agents for Treasury, as 
permitted by the Federal Reserve Act. As fiscal agents for Treasury, 
the FRBs play a significant role in the processing of marketable book-
entry securities and paper U.S. savings bonds. For marketable book-
entry securities, selected FRBs receive bids, issue book-entry 
securities to awarded bidders, and collect payments on behalf of 
Treasury; and make interest and redemption payments from Treasury's 
account to the accounts of security holders. For paper U.S. savings 
bonds, selected FRBs print and deliver savings bonds purchased with 
federal income tax refunds; and redeem savings bonds, including 
handling the related transfers of cash. 

Intragovemmental Debt Holdings: 

Intragovenunental debt holdings represent balances of Treasury 
securities held by 239 individual federal government accounts with 
either the authority or the requirement to invest excess receipts in 
special U.S. Treasury securities that are guaranteed for principal and 
interest by the full faith and credit of the U.S. Government.
Intragovenunental debt holdings primarily consist of balances in the 
Social Security, Medicare, Military Retirement and Health Care, and 
Civil Service Retirement and Disability trust funds.[Footnote 2] As of 
September 30, 2012, such funds accounted for $4,389 billion, or 92 
percent, of the $4,789 billion intergovernmental debt holdings 
balances (see Figure 4). As of September 30, 2012 and 2011, gross 
intragovernmental debt holdings totaled $4,789 billion and $4,654 
billion, respectively (see Figure 1), an increase of $135 billion. 

The majority of intragovemmental debt holdings are Government Account 
Series (GAS) securities. GAS securities consist of par value 
securities and market-based securities, with terms ranging from on 
demand out to 30 years. Par value securities are issued and redeemed 
at par (100 percent of the face value), regardless of current market
conditions. Market-based securities, however, can be issued at a 
premium or discount and are redeemed at par value on the maturity date 
or at market value if redeemed before the maturity date.

September 30, 2012:

Social Security trust funds: 57%; 
Civil Service Retirement and Disability trust fund: 17%;

Significant Events in Fiscal Year 2012: 

Statutory Debt Limit Raised: 

Prior to the enactment of the Budget Control Act of 2011, which was 
signed into law on August 2, 2011, (Public Law No, 112-25), delays in 
raising the statutory debt limit occurred that required Treasury to 
depart from its normal debt management procedures and invoke legal 
authorities to avoid exceeding the statutory debt limit. In accordance 
with relevant legislation, on December 30, 2011, BPD restored the 
Civil Service Retirement and Disability Fund (Civil Service Fund) and 
the Postal Service Retiree Health Benefits Fund (Postal Benefits Fund) 
portfolios for the interest lost front the delays in raising the 
statutory debt limit, which ended on August 2, 2011. The restoration 
amounted to nearly $517 million for the Civil Service Fund and $22 
million for the Postal Benefits Fund. 

After close of business on January 27, 2012, the statutory debt limit 
was increased by $1.2 trillion, from $15.194 trillion to $16.394 
trillion. The increase was authorized under the terms of the Budget 
Control Act of 2011. However, prior to the statutory debt limit 
increase, beginning on January 4, 2012, delays in raising the 
statutory debt limit resulted in Treasury departing from its normal 
debt management procedures and invoking legal authorities to keep the 
debt outstanding no closer than $25 million to the statutory debt 
limit. Treasury maintained the $25 million window by utilizing 
extraordinary actions within its legal authorities, which included 
suspending investments of the Exchange Stabilization Fund (ESF) and 
the Government Securities Investment Fund of the Federal Employees'
Retirement System (G-Fund). 

In accordance with relevant legislation, on January 30, 2012, BPD 
restored foregone principal and interest for the G-Fund totaling $36.9 
billion and foregone principal to the ESF totaling $22.7 billion. BPD 
only restored forgone principal to the ESF as the ESF is not entitled 
to interest losses resulting from authorized actions taken by Treasury 
to manage federal debt when delays in miring the debt limit occur. 

FY 2013 Budget Proposes BPD and Financial Management Service (FMS)
Consolidation: 

In his fiscal year 2013 Budget request, President Obama proposed a 
consolidation of BPD and FMS, both under Treasury's Office of the 
Fiscal Assistant Secretary (OFAS), into one organization called the 
Bureau of the Fiscal Service. Beyond the financial and operational 
benefits, this effort will enable the Department of the Treasury to 
better address the financial management needs of the federal 
government and realize administrative efficiencies while retaining 
existing core federal financial management responsibilities. Beginning 
in fiscal year 2014, the combined BPD and FMS cumulative net savings 
from the proposed consolidation is projected to be $36 million over a 
five year period. Areas identified for cost reduction included: 

* Headquarters staff, by transitioning to one Commissioner responsible 
for Fiscal Service operations; 

* Finance and budget, by transitioning to one Chief Financial Officer; 

* Information technology, by transitioning to one Chief Information 
Officer; 

* Legal support, by transitioning to one Chief Counsel; and; 

* Legislative and Public Affairs, by transitioning to one office. 

The proposed consolidation of BPD and FMS will position the Fiscal 
Service to create a new standard of excellence and leadership for the 
federal community. 

Ready.Save.Grow: 

On March 27, 2012, BPD kicked off a public education campaign, 
Ready.Save.Grow.[SM} to raise awareness of Treasury securities and to 
remind the public that, although paper savings bonds can only be 
purchased with tax refunds, electronic savings bonds remain available 
through TreasuryDirect. To aid the campaign, BPD is partnering with 
several non-profit organizations such as AARP, American Savings 
Education Council, Center for Financial Services Innovation, and 
Consumer Federation of America The campaign's website [hyperlink, 
http://www.treasurydirect.gov/readysavegrow] organizes Treasury 
investment information in an easy-to-read format for new and 
prospective investors. The Treasurer of the United States is the 
spokesperson for the campaign. 

Historical Perspective: 

Federal debt outstanding is one of the largest legally binding 
obligations of the Federal Government. Nearly all the federal debt has 
been issued by the Treasury with a small portion being issued by other 
federal government agencies. Treasury issues debt securities for two 
principal reasons, (1) to borrow needed funds to finance the current 
operations of the Federal Government and (2) to provide an investment 
and accounting mechanism for certain federal government accounts' 
(primarily federal trust funds) excess receipts. Total gross federal 
debt outstanding has dramatically increased over the past 25 years 
from $2,350 billion as of September 30, 1987, to $16,059 billion as of 
September 30, 2012 (see Figure 5). Large budget deficits emerged 
during the 1980's due to tax policy decisions and increased outlays 
for defense and domestic programs. Through fiscal year 1997, annual 
federal deficits continued to be large and debt continued to grow at a 
rapid pace. As a result, total federal debt mom than doubled between 
1987 and 1997.

[End of figure] 
                          
By fiscal year 1998, federal debt held by the public was beginning to 
decline. In fiscal years 1998 through 2001, the amount of debt held by 
the public fell by $476 billion, from $3,815 billion to $3,339 
billion. However, federal debt held by the public began to increase in 
fiscal year 2002, primarily as a result of higher federal outlays. 
Federal debt held by the public increased by 51.2 percent from fiscal 
year 2002 through fiscal year 2007. From fiscal year 2008 through 
fiscal year 2012, federal debt held by the public more than doubled, 
rising by $6,221 billion. This increase was primarily a result of the 
economic downturn and the federal government's response to it. Since 
fiscal year 2002, debt held by the public has increased from $3,339 
billion as of September 30, 2001 to $11,270 billion as of September 
30, 2012. 
 
Even in those years where debt held by the public declined, total 
federal debt increased because of increases in intragovernmental debt 
holdings. Over the past 4 fiscal years, intragovernmental debt 
holdings increased by $587 billion, from $4,202 billion as of 
September 30, 2008, to $4,789 billion as of September 30, 2012. By 
law, federal government accounts, including trust funds, have the 
authority or are required to invest their excess annual receipts  
(including interest earnings) over disbursements in federal 
securities. As a result, the intragovenunental debt holdings balances 
primarily represent the cumulative surplus of funds due to the trust 
funds' cumulative annual excess of tax receipts, interest credited, 
and other collections compared to spending. 

As shown in Figure 6, interest rates have fluctuated over the past 25 
years. The average interest rates reflected here represent the 
original issue weighted effective yield on debt held by the public and 
intragovenunental debt holdings outstanding at the end of the fiscal 
year.

Notes to the Schedules of Federal Debt: 

Notes to the Schedules of Federal Debt Managed by the Bureau of the 
Public Debt For the Fiscal Years Ended September 30, 2012 and 2011: 

(Dollars in Millions) 

Note 1. Significant Accounting Policies: 

Basis of Presentation: 

The Schedules of Federal Debt Managed by the Bureau of the Public Debt 
(BPD) have been prepared to report fiscal year 2012 and fiscal year 
2011 balances and activity relating to monies borrowed from the public 
and certain federal government accounts under 31 U.S.C. § 3101 to fund 
the operations of the U.S. government. Permanent indefinite 
appropriations are available for the payment of interest on the 
federal debt and the redemption of Treasury securities. 

Reporting Entity: 

The Constitution empowers the Congress to borrow money on the credit 
of the United States. The Congress has authorized the Secretary of the 
Treasury to borrow monies to operate the federal government within a 
statutory debt limit. Title 31, U.S. Code authorizes Treasury to 
prescribe the debt instruments and otherwise limit and restrict the 
amount and composition of the debt. BPD, an organizational entity 
within the Fiscal Service of the Department of the Treasury, is 
responsible for issuing Treasury securities in accordance with such 
authority and to account for the resulting debt. In addition, BPD 
maintains an investment program for federal government accounts, 
including trust funds, that have legislative authority to invest 
temporary cash reserves not needed for current benefits and expenses.
BPD issues and redeems Treasury securities for these federal 
government accounts based on data provided by the respective program 
agencies and other Treasury entities. BPD also issues other specific 
securities outside of the authority of 31 U.S.C. § 3101, such as HOPE 
Bonds, that are not reported on the Schedules of Federal Debt Managed 
by the Bureau of the Public Debt. 

Basis of Accounting: 

The schedules were prepared in conformity with U.S. generally accepted 
accounting principles and from BPD's automated debt accounting system. 
Accounting principles generally accepted for Federal entities are the 
standards prescribed by the Federal Accounting Standards Advisory 
Board (FASAB), which is the official body for setting accounting 
standards of the Federal government. The FASAB issued the Statement of 
Federal Financial Accounting Standards (SFFAS) No. 34, The Hierarchy 
of Generally _Accepted Accounting Principles, Including the 
Application of Standards Issued by the Financial Accounting Standards 
Board in July 2009. SFFAS No. 34 identifies the sources of accounting 
principles and the framework for selecting the principles used in the 
preparation of general purpose financial reports of federal reporting 
entities that are presented in conformity with Federal generally 
accepted accounting principles. 

Interest costs are recorded as expenses when incurred, instead of when 
paid. Certain Treasury securities are issued at a discount or premium. 
These discounts and premiums are amortized over the term of the 
security using an interest method for all long term securities and the 
straight line method for short term securities. The Department of the 
Treasury also issues Treasury Inflation-Protected Securities (TIPS). 
The principal for TIPS is adjusted daily over the life of the security 
based on the Consumer Price Index for all Urban Consumers.

Total Federal Debt Held by the Public: 
2012 Amount: $11,269,586;

Treasury issues marketable bills usually at a discount, but may also 
issue at par, and pays the par amount of the security upon maturity. 
The average interest rate on Treasury bills represents the original 
issue effective yield on securities outstanding as of September 30, 
2012 and 2011. Treasury bills are issued with a term of one year or 
less. Treasury issues marketable notes and bonds as long-term 
securities that pay semi-annual interest based on the securities' 
stated interest rate. These securities are issued at either par value 
or at an amount that reflects a discount or a premium. The average 
interest rate on marketable notes and bonds represents the stated 
interest rate adjusted by any discount or premium on securities 
outstanding as of September 30, 2012 and 2011. Treasury notes are 
issued with a term of 2—10 years and Treasury bonds are issued with a 
term of more than 10 years. 

Treasury also issues TIPS that have interest and redemption payments 
that are tied to the Consumer Price Index for all Urban Consumers, a 
widely used measure of inflation TIPS are issued with a term of 5 
years or more. At maturity, TIPS ate redeemed at the inflation-
adjusted principal amount, or the original par value, whichever is 
greater. TIPS pay a semi-annual fixed rate of interest applied to the 
inflation-adjusted principal. The average interest rate on TIPS 
represents the stated interest rate on principal plus inflation, 
adjusted by any discount or premium on securities outstanding as of 
September 30, 2012 and 2011. The TIPS Federal Debt Held by the Public 
inflation-adjusted principal balance includes inflation of $77,909 
million and $76,133 million as of September 30, 2012 and 2011, 
respectively. 

Federal Debt Held by the Public includes federal debt held outside of 
the U. S. government by individuals, corporations, Federal Reserve 
Banks (FRB), state and local governments, and foreign governments and 
central banks. As of September 30, 2012, the FRB had total holdings of 
$1,646,809 million, including a net of $1,523 million in Treasury 
securities held by the FRB as collateral for securities lending 
activities. As of September 30, 2011, the FRB had total holdings of 
$1,665,419 million, including a net of $759 million in Treasury 
securities held by the FRB as collateral for securities lending 
activities. These securities are held in the FRB System
Open Market Account (SOMA) for the purpose of conducting monetary 
policy. 

Treasury issues nonmarketable securities at either par value or at an 
amount that reflects a discount or a premium. The average interest 
rate on the nonmarketable securities represents the original issue 
weighted effective yield on securities outstanding as of September 30, 
2012 and 2011. Nonmarketable securities are issued with a term of on 
demand out to 40 years. 

As of September 30, 2012 and 2011, nonmarketable securities consisted 
of the following: 

Domestic Series: 
2012: $29,995; 
2011: $29,995. 

Foreign Series: 
2012: $2,986; 
2011: $2,986. 

State and Local Government Series: 
2012: $158,514; 
2011: $151,831. 

United States Savings Securities:

2012: $162,880; 
2011: $151,346. 

Other: 
2012: $1,380; 
2011: $1,386. 

Total Nonmarketable: 
2012: $539,416; 
2011: $522,731. 

Government Account Series (GAS) securities are nonmarketable 
securities issued to federal government accounts. Federal Debt Held by 
the Public includes GAS securities issued to certain federal 
government accounts. One example is the GAS securities held by the 
Government Securities Investment Fund (G-Fund) of the federal 
employees' Thrift Savings Plan. Federal employees and retirees who 
have individual accounts own the GAS securities held by the fund. For 
this reason, these securities are considered part of the Federal Debt 
Held by the Public rather than Intragovenunental Debt Holdings. The 
GAS securities held by the G-Fund consist of overnight investments 
redeemed one business day after their issue. The net increase in 
amounts borrowed from the fund during fiscal years 2012 and 2011 are 
included in the respective Borrowings from the Public amounts reported 
on the Schedules of Federal Debt. 

Fiscal year-end September 30, 2012, occurred on a Sunday. As a result, 
$53,003 million of marketable Treasury notes, $35 million of 
Government Account Series securities, and $1 million of State and 
Local Government Series securities, matured but not repaid are 
included in the balance of the total debt held by the public as of
September 30, 2012. Settlement of this debt repayment occurred on 
Monday, October 1, 2012.

interest rates on Intragovernmental Debt Holdings, excluding TIPS, for 
fiscal years 2012 and 2011 were 3.7 and 4.1 percent, respectively. The 
average interest rates on TIPS for fiscal years 2012 and 2011 were 1.5 
and 1.8 percent, respectively. The average interest rate represents 
the original issue weighted effective yield on securities outstanding

Appendix I: Management's Report on Internal Control over Financial 
Reporting Relevant to the Schedule of Federal Debt: 

Management's Report on Internal Control over Financial Reporting
Relevant to the Schedule of Federal Debt: 

The Bureau of the Public Debt's (BPD) internal control over financial 
reporting relevant to the Schedule of Federal Debt is a process 
effected by those charged with governance, management, and other 
personnel, the objectives of which are to provide reasonable assurance 
that (1) transactions are properly recorded, processed, and summarized 
to permit the preparation of the Schedule of Federal Debt in 
conformity with U.S. generally accepted accounting principles; and (2) 
transactions related to the Schedule of Federal Debt are executed in 
accordance with laws governing the use of budget authority and other 
laws and regulations that could have a direct and material effect on 
the Schedule of Federal Debt. 

BPD management is responsible for establishing and maintaining 
effective internal control over financial reporting. BPD management 
evaluated the effectiveness of BPD's internal control over financial 
reporting relevant to the Schedule of Federal Debt as of September 30, 
2012, based on the criteria established under 31 U.S.C. § 3512(c), (d) 
(commonly known as the Federal Managers' Financial Integrity Act). 

Based on that evaluation, we conclude that, as of September 30, 2012, 
BPD's internal control over financial reporting relevant to the 
Schedule of Federal Debt was effective.

Control Act of 2011 (Pub. L. No. 112-25), which established a process 
that resulted in debt limit increases in three increments--$400 
billion effective on August 2, 2011, $500 billion effective after 
close of business on September 21, 2011, and $1,200 billion effective 
after close of business on January 27, 2012.

[11] The BCA (Pub. L. No. 112-25) enacted caps on discretionary 
spending for fiscal years 2012 through 2021. In addition, the BCA 
specified additional limits on discretionary spending and automatic 
reductions in direct spending that would take effect if lawmakers did 
not enact legislation originating from the Joint Select Committee on 
Deficit Reduction that would reduce projected deficits by at least 
$1.2 trillion. Because no such legislation was enacted, those 
procedures are now scheduled to go into effect.

[13] 31 U.S.C. § 331(e)(2). As a bureau within the Department of the 
Treasury, federal debt and related activity and balances managed by 
BPD are also significant to the consolidated financial statements of 
the Department of the Treasury (see 31 U.S.C. § 3515(b)). 

[14] [2] Debt held by the public represents federal debt issued by 
Treasury and held by investors outside of the federal government, 
including individuals, corporations, state or local governments, the 
Federal Reserve, and foreign governments. Intragovernmental debt 
holdings represent federal debt owed by Treasury to federal government 
accounts, primarily federal trust funds such as Social Security and 
Medicare. 

[15] [3] A material weakness is a deficiency, or a combination of 
deficiencies, in internal control such that there is a reasonable 
possibility that a material misstatement of the entity's financial 
statements will not be prevented, or detected and corrected, on a 
timely basis. A significant deficiency is a deficiency, or combination 
of deficiencies, in internal control that is less severe than a 
material weakness, yet important enough to merit attention by those 
charged with governance. A deficiency in internal control exists when 
the design or operation of a control does not allow management or 
employees, in the normal course of performing their assigned 
functions, to prevent, or detect and correct, misstatements on a 
timely basis.
