Note 1. Significant Accounting Policies

A. Basis of Presentation

The Departmental consolidated financial statement has been prepared to report the financial position and results from operations of the Department of Transportation (DOT), as required by the Chief Financial Officers Act of 1990, Title IV of the Government Management Reform Act of 1994. The statement has been prepared from the books and records of DOT in accordance with Office of Management and Budget (OMB) requirements for form and content for entity financial statements and DOT’s accounting policies and procedures. OMB Circular No. A-136, Financial Reporting Requirements, has been used to prepare the Balance Sheet, Statement of Changes in Net Position, Statement of Budgetary Resources, and Statement of Financing. They are different from the financial reports prepared pursuant to OMB directives that are used to monitor and control the use of budgetary resources.

The Balance Sheet presents agency assets and liabilities, and the difference between the two, which is the agency net position. Agency assets include both entity assets (those which are available for use by the agency) and non-entity assets (those which are managed by the agency but not available for use in its operations). Agency liabilities include both those covered by budgetary resources (funded) and those not covered by budgetary resources (unfunded).

The Statement of Net Cost presents the gross costs of programs less earned revenue to arrive at the net cost of operations for both programs and for the agency as a whole.

The Statement of Changes in Net Position reports beginning balances, budgetary and other financing sources, and net cost of operations, to arrive at ending balances.

The Statement of Budgetary Resources provides information about how budgetary resources were made available as well as their status at the end of the period. Recognition and measurement of budgetary information reported on this statement is based on budget terminology, definitions, and guidance in OMB Circular No. A-11, Preparation, Submission, and Execution of the Budget, dated June 2006.

The Statement of Financing is intended to be a bridge between an entity’s budgetary and financial (i.e., proprietary) accounting. The Statement of Financing illustrates the relationship between net obligations derived from an entity’s budgetary accounts and net cost of operations derived from an entity’s proprietary accounts by identifying and explaining key differences between the two numbers. Since DOT custodial activity is incidental to Departmental operations and not material, a Statement of Custodial Activity was not prepared. However, sources and dispositions of collections have been disclosed in Note 23 to the financial statements.

The Department is required to be in substantial compliance with all applicable accounting principles and standards established, issued, and implemented by the Federal Accounting Standards Advisory Board, which is recognized by the American Institute of Certified Public Accountants as the entity to establish Generally Accepted Accounting Principles (GAAP) for the Federal Government. The Federal Financial Management Improvement Act of 1996 requires the Department to comply substantially with (1) Federal financial management systems requirements, (2) applicable Federal accounting standards, and (3) the U.S. Government Standard General Ledger at the transaction level.

B. Reporting Entity

DOT serves as the focal point in the Federal Government for the Coordinated National Transportation Policy. It is responsible for ensuring the safety of all forms of transportation; protecting the interests of consumers; international transportation agreements; conducting planning and research for the future; and helping cities and States meet their local transportation needs through financial and technical assistance.

The Department is comprised of the Office of the Secretary and the DOT Operating Administrations, each having its own management and organizational structure and collectively providing the necessary services and oversight to ensure the best transportation system possible. The Departmental consolidated financial statement represents the financial data, including various trust funds, revolving funds, appropriations and special funds of the following organizations:

• Office of The Secretary (OST - includes OST Working Capital Fund)
• Federal Aviation Administration (FAA)
• Federal Highway Administration (FHWA)
• Federal Motor Carrier Safety Administration (FMCSA)
• Federal Railroad Administration (FRA)
• National Highway Traffic Safety Administration (NHTSA)
• Maritime Administration (MARAD)
• Federal Transit Administration (FTA)
• Surface Transportation Board (STB)
• Office of Inspector General (OIG)
• Pipeline and Hazardous Materials Safety Administration (PHMSA)
• Research and Innovative Technology Administration (RITA—includes Volpe National Transportation System Center)

In November 2004, President Bush signed into law the Norman Y. Mineta Research and Special Program Improvement Act to be enacted in February 2005. This new law split Research and Special Programs Administration (RSPA) who ceases to exist into two different entities, Research and Innovative Technology Administration (RITA) and Pipeline and Hazardous Materials Safety Administration (PHMSA).

The Saint Lawrence Seaway Development Corporation (SLSDC) is also an entity of DOT. However, since it is subject to separate reporting under the Government Corporation Control Act and the dollar value of its activities is not material to Departmental totals, SLSDC’s financial data have not been consolidated in the DOT financial statements. However, condensed information about SLSDC’s financial position is included in Note 24.

C. Budgets and Budgetary Accounting

DOT follows standard Federal budgetary accounting policies and practices in accordance with OMB Circular No. A-11, Preparation, Submission, and Execution of the Budget, dated June 2006. Budgetary accounting facilitates compliance with legal constraints and controls over the use of Federal funds. Each year, Congress provides each Operating Administration within DOT appropriations to incur obligations in support of agency programs. For FY 2006, the Department was accountable for trust fund appropriations, general fund appropriations, revolving funds and borrowing authority. DOT recognizes budgetary resources as assets when cash (funds held by Treasury) is made available through warrants and trust fund transfers.

D. Basis of Accounting

Transactions are generally recorded on an accrual accounting basis and a budgetary basis. Under the accrual method, revenues are recognized when earned, and expenses are recognized when a liability is incurred, without regard to receipt or payment of cash. Budgetary accounting facilitates compliance with legal constraints and controls over the use of Federal funds.

DOT accounted for revenues and other financing sources for earmarked funds separately from other funds. This new method was adopted in accordance with the provisions of the Federal Accounting Standards Advisory Board’s Statement of Federal Financial Accounting Standards (SFFAS) No. 27, Identifying and Reporting Earmarked Funds, which became effective October 1, 2005. This new standard amended SFFAS No. 7, Revenue and Other Financing Sources, by: (1) elaborating the special accountability needs associated with dedicated collections; (2) separating dedicated collections into two categories—earmarked funds and fiduciary activity; and (3) defining and providing accounting and reporting guidance for earmarked funds.

In accordance with SFFAS No. 27, DOT did not restate the prior period columns of the consolidated financial statements and related notes. See Note 18 for specific required disclosures related to the DOT’s earmarked funds.

E. Revenues and Other Financing Sources

DOT receives the majority of the funding needed to support all of its programs through appropriations. The Highway Trust Fund, Airport and Airway Trust Fund, and the Treasury General Fund fund some of these appropriations. DOT receives annual, multi-year and no-year appropriations that may be used, within statutory limits, for operating and capital expenditures. Additional amounts are obtained from offsetting collections and user fees (e.g., landing and registry fees) and through reimbursable agreements for services performed for domestic and foreign governmental entities. Additional revenue is earned from gifts from donors, sales of goods and services to other agencies and the public, the collection of fees and fines, interest/dividends on invested funds, loans and cash disbursements to banks. Interest income received is recognized as revenue on the accrual basis. Appropriations are recognized as revenues as the related program or administrative expenses are incurred.

F. Funds With the U.S. Treasury and Cash

DOT does not generally maintain cash in commercial bank accounts. Cash receipts and disbursements are processed by the U.S. Treasury. The funds with the U.S. Treasury are appropriated, revolving, and trust funds that are available to pay current liabilities and finance authorized purchases. DOT has substantially reduced the number of petty cash (imprest) funds outside the U.S. Treasury to reduce the amount of cash paid outside of Treasury. This reduces the amount of interest that must be paid to borrow funds. Lockboxes have been established with financial institutions to collect payments, and these funds are transferred directly to Treasury on a daily (business day) basis. DOT does not maintain any balances of foreign currencies.

G. Receivables

Accounts receivable consist of amounts owed to the Department by other Federal agencies and the public. Federal accounts receivable are generally the result of the provision of goods and services to other Federal agencies and, with the exception of occasional billing disputes, are considered to be fully collectible. Public accounts receivable are generally the result of the provision of goods and services or the levy of fines and penalties from the Department’s regulatory activities. Amounts due from the public are presented net of an allowance for loss on uncollectible accounts, which is based on historical collection experience and/or an analysis of the individual receivables.

Loans are accounted for as receivables after funds have been disbursed. For loans obligated prior to October 1, 1991, loan principal, interest, and penalties receivable are reduced by an allowance for estimated uncollectible amounts. The allowance is estimated based on past experience, present market conditions, and an analysis of outstanding balances. Loans obligated after September 30, 1991, are reduced by an allowance equal to the present value of the subsidy costs (due to the interest rate differential between the loans and Treasury borrowing, the estimated delinquencies and defaults net of recoveries, the offset from fees, and other estimated cash flows) associated with these loans.

H. Inventory and Operating Materials and Supplies

Inventory primarily consists of supplies that are for sale or used in the production of goods for sale. Operating materials and supplies primarily consist of unissued supplies that will be consumed in future operations. Valuation methods for supplies on hand at yearend include historical cost, last acquisition price, standard price/specific identification, standard repair cost, weighted average, and moving weighted average. Expenditures or expenses are recorded when the materials and supplies are consumed or sold. Adjustments for the proper valuation of reparable, excess, obsolete, and unserviceable items are made to appropriate allowance accounts.

I. Investments in U.S. Government Securities

Investments that consist of U.S. Government Securities are reported at cost or amortized cost net of premiums or discounts. Premiums or discounts are amortized into interest income over the term of the investment using the interest or straight-line method. The Department’s intent is to hold investments to maturity, unless they are needed to cover losses on loan guarantees, finance programs, or otherwise sustain the operation of the organization. Investments, redemptions, and reinvestments are controlled and processed by the Department of the Treasury.

J. Property and Equipment

DOT agencies have varying methods of determining the value of property and equipment and how it is depreciated. DOT currently has a capitalization threshold of $200,000 for structures and facilities and for internal use software, and $25,000 for other property, plant and equipment. Capitalization at lesser amounts is permitted. Construction in progress is valued at direct (actual) costs plus applied overhead and other indirect costs as accumulated by the regional project material system. The system accumulates costs by project number assigned to the equipment or facility being constructed. The straight-line method is generally used to depreciate capitalized assets.

FASAB standards require DOT stewardship assets to be omitted from the Balance Sheet. Information on DOT stewardship assets, as well as stewardship investments, is presented in the Required Supplementary Information section and the Required Supplementary Stewardship Reporting section of this statement. See Note 10 for specific required disclosures related to Stewardship Heritage Assets.

K. Prepaid and Deferred Charges

Payments in advance of the receipt of goods and services are recorded as prepaid charges at the time of prepayment and recognized as expenses when the related goods and services are received.

L. Liabilities

Liabilities represent amounts expected to be paid as the result of a transaction or event that has already occurred. Liabilities covered by budgetary resources are liabilities incurred which are covered by realized budgetary resources as of the balance sheet data. Available budgetary resources include new budget authority, spending authority from offsetting collections, recoveries of unexpired budget authority through downward adjustments of prior year obligations, unobligated balances of budgetary resources at the beginning of the year or net transfers of prior year balances during the year, and permanent indefinite appropriations or borrowing authority. Unfunded liabilities are not considered to be covered by such budgetary resources. An example of an unfunded liability is actuarial liabilities for future Federal Employees’ Compensation Act payments. The Government, acting in its sovereign capacity, can abrogate liabilities arising from other than contracts.

M. Contingencies

The criteria for recognizing contingencies for claims are (1) a past event or exchange transaction has occurred as of the date of the statements; (2) a future outflow or other sacrifice of resources is probable; and (3) the future outflow or sacrifice of resources is measurable (reasonably estimated). DOT recognizes material contingent liabilities in the form of claims, legal action, administrative proceedings and environmental suits that have been brought to the attention of legal counsel, some of which will be paid by the Treasury Judgment Fund. It is the opinion of management and legal counsel that the ultimate resolution of these proceedings, actions and claims, will not materially affect the financial position or results of operations.

N. Annual, Sick, and Other Leave

Annual leave is accrued as it is earned, and the accrual is reduced as leave is taken. Accruals for other leave (e.g., credit hours and compensatory leave) are also recorded in the financial statement. Under the OST Working Capital Fund, the liability for accrued annual leave is a funded item. To the extent current or prior year appropriations are not available to fund annual leave earned but not taken, funding will be obtained from future financing sources. Sick leave and other types of non-vested leave are expended as taken.

Air Traffic Controllers covered under the Federal Employees Retirement System (FERS) are eligible, upon retirement, for a sick leave buy back option. Under this option, an employee who attains the required number of years of service for retirement shall receive a lump sum payment for forty percent of the value of his or her accumulated sick leave as of the effective date of retirement.

O. Retirement Plan

For DOT employees who participate in the Civil Service Retirement System (CSRS), DOT contributes a matching contribution equal to 7 percent of pay. On January 1, 1987, FERS went into effect pursuant to Public Law (P.L.) 99-335. Most employees hired after December 31, 1983, are automatically covered by FERS and Social Security. Employees hired prior to January 1, 1984, could elect to either join FERS and Social Security or remain in CSRS. A primary feature of FERS is that it offers a savings plan to which DOT automatically contributes 1 percent of pay and matches any employee contribution up to an additional 4 percent of pay. For most employees hired since December 31, 1983, DOT also contributes the employer’s matching share for Social Security.

Employing agencies are required to recognize pensions and other post retirement benefits during the employees’ active years of service. Reporting the assets and liabilities associated with such benefits is the responsibility of the administering agency, the Office of Personnel Management. Therefore, DOT does not report CSRS or FERS assets, accumulated plan benefits, or unfunded liabilities, if any, applicable to employees.

P. Comparative Data

Comparative data for the prior year have been presented for the principal financial statements and their related notes.

Q. Use of Estimates

Management has made certain estimates and assumptions when reporting assets, liabilities, revenue, expenses, and in the note disclosures. Actual results could differ from these estimates. Significant estimates underlying the accompanying financial statements include (a) the allocation of trust fund receipts by the Office of Treasury’s Assessment (OTA), (b) yearend accruals of accounts and grants payable, (c) accrued workers’ compensation, and (d) allowance for doubtful accounts receivable. Actual results may differ from these estimates.

R. Reclassifications

Certain reclassifications were made to the FY 2005 financial statement presentation to conform with that used in FY 2006.

S. Parent/Child Allocations

According to OMB Circular No. A-136, effective FY 2007 the parent must report all budgetary and proprietary activity of the child account in its financial statements, whether material to the parent or not. For FY 2006, DOT implemented this requirement early as agreed upon by its child agencies and reported all budgetary and proprietary activity in its financial statements, except for the proprietary activity related to the funds allocated to the U.S. Army Corps of Engineers and

U.S. Forest Service.

NOTE 2. NON-ENTITY ASSETS

NOTE 3. FUND BALANCE WITH TREASURY

Fund Balances

Fund Balances with Treasury are the aggregate amounts of the entity’s accounts with Treasury for which the entity is authorized to make expenditures and pay liabilities. Other Fund Types include uncleared Suspense Accounts, which temporarily hold collections pending clearance to the applicable account, and Deposit Funds, which are established to record amounts held temporarily until ownership is determined.

NOTE 4. INVESTMENTS

As of September 30, 2006
Dollars in Thousands

As of September 30, 2005
Dollars in Thousands

Investments in Federal securities include non-marketable par value Treasury securities, market-based Treasury securities, marketable Treasury securities, and securities issued by other Federal entities. Non-Federal securities include those issued by State and local governments, Government-sponsored enterprises, and other private corporations.

Marketable Federal securities can be bought and sold on the open market. Non-marketable par value Treasury securities are issued by the Bureau of Public Debt to Federal accounts and are purchased and redeemed at par exclusively through Treasury’s Federal Investment Branch. Nonmarketable market-based Treasury securities are also issued by the Bureau of Public Debt to Federal accounts. They are not traded on any securities exchange but mirror the prices of particular Treasury securities trading in the Government securities market. Amortization is done using the interest or straight-line method.

The Federal Government does not set aside assets to pay future benefits or other expenditures associated with earmarked funds. The cash receipts collected from the public for an earmarked fund are deposited in the U.S. Treasury, which uses the cash for Government purposes. Treasury securities are issued to the DOT as evidence of its receipts. Treasury securities are an asset to the DOT and a liability to the U.S. Treasury. Because the DOT and the U.S. Treasury are both parts of the Government, these assets and liabilities offset each other from the standpoint of the Government as a whole. For this reason, they do not represent an asset or liability in the U.S. Government-wide financial statements.

Treasury securities provide the DOT with authority to draw upon the U.S. Treasury to make future benefit payments or other expenditures. When the DOT requires redemption of these securities to make expenditures, the Government finances those expenditures out of accumulated cash balances, by raising taxes or other receipts, by borrowing from the public or repaying less debt, or by curtailing other expenditures. This is the same way that the Government finances all other expenditures.

NOTE 5. ACCOUNTS RECEIVABLE

Allowance for Uncollectible Amounts is based on historical data or actual amounts that are determined to be uncollectible based upon review of individual receivables. Accrued interest includes interest, penalties, and other administrative charges pertaining to accounts receivable.

NOTE 6. OTHER ASSETS

Intragovernmental Other Assets are comprised of advance payments to other Federal Government entities for agency expenses not yet incurred and for goods or services not yet received and undistributed assets and payments for which DOT is awaiting documentation. Public Other Assets are comprised of advances to the States and advances to employees and contractors.

DOT administers the following direct loan and/or loan guarantee programs:

1. Railroad Rehabilitation Improvement Program

2. Amtrak Loans

3. Transportation Infrastructure Finance Innovation Act (TIFIA) Loan

4. Federal Ship Financing Fund (Title XI)

5. OST Minority Business Resource Center Guaranteed Loan Program

6. Federal Ship (Title XI) Liquidating Fund

An analysis of loans receivable, allowance for subsidy costs, liability for loan guarantees, foreclosed property, modifications, reestimates, and administrative costs associated with the direct loans and loan guarantees is provided in the following sections.

SCHEDULE FOR RECONCILING LOAN GUARANTEE LIABILITY BALANCES (POST-1991 LOAN GUARANTEES)

The Federal Credit Reform Act of 1990 divides direct loans and loan guarantees into two groups:

(1) Pre-1992 means the direct loan obligations or loan guarantee commitments made prior to FY 1992 and the resulting direct loan obligations or loan guarantees, and (2) Post-1991 means the direct loan obligations or loan guarantee commitments made after FY 1991 and the resulting direct loans or loan guarantees.

The Act provides that, for direct loan obligations or loan guarantee commitments made after FY 1991, the present value of the subsidy costs (which arises from interest rate differentials, interest subsidies, delinquencies and defaults, fee offsets, and other cash flows) associated with direct loans and loan guarantees be recognized as a cost in the year the direct or guaranteed loan is disbursed.

Direct loans are reported net of an allowance for subsidy at present value, and loan guarantee liabilities are reported at present value. Foreclosed property is valued at the net realizable value. Loans receivable, net, or their value of assets related to direct loans, is not the same as the proceeds that they would expect to receive from selling their loans. DOT calculated the allowance for pre-1992 using the allowance for loss method.

Administrative costs could not be determined and disclosed because DOT has not fully implemented cost accounting Department-wide.

NOTE 8. INVENTORY AND RELATED PROPERTY

All DOT inventory is in FAA and the OST Working Capital Fund. Valuation methods used include moving weighted average, standard price/specific identification, and last acquisition price.

DOT operating materials and supplies are in FAA and MARAD. Valuation methods used include historical cost, last acquisition price, standard price/specific identification, standard repair cost, weighted average, and moving weighted average. The only restriction on use is that FAA is not permitted to donate.

NOTE 9. GENERAL PROPERTY, PLANT AND EQUIPMENT

Depreciation is computed using the straight line method. Net book value of multi-use heritage assets is now included in general property, plant and equipment, while “physical quantity” information is included in the Heritage Assets section of Required Supplementary Information.

Note 10. Stewardship Property, Plant and Equipment

STEWARDSHIP MISSION

Implied within the Maritime Administration's mission is the promotion of the Nation's rich maritime heritage. One aspect of this entails the collection, maintenance and distribution of maritime artifacts removed from MARAD ships prior to their disposal. These artifacts are sought for public display in museums, aboard memorial ships, and in facilities used by government organizations and issued on a long-term loan basis for this purpose.

Washington's Union Station support's DOT's mobility mission, facilitating the movement of intercity and commuter rail passengers through the Washington DC metropolitan area.

STEWARDSHIP POLICY

The Maritime Administration has established a list of artifact-type items that are typically found aboard agency-owned ships. As ships are assigned to a non-retention status in preparation for disposal, artifact items are collected, inventoried, photographed and relocated to secure shoreside storage facilities. This resulting inventory of artifacts is made available for long-term loan to qualified organizations for public display purposes. Qualified organizations have access to the artifact inventory via Web-based system. The artifact loan process is also managed on-line via this system. The program also supports required National Historical Preservation Act processing prior to vessel disposal. Funding for the maintenance of heritage items is typically the responsibility of the organization requesting the loan. As all items are durable and restorable, disposal is not a consideration.

The Federal Railroad Administration has an oversight role in the management of Washington Union Station. FRA received title through legislation, and sublets the property to Union Station Venture Limited which manages the property.

Net book value of multi-use heritage assets is included in general property, plant and equipment, while "physical quantity" information is included in the Heritage Assets section of Required Supplementary Information. The condition of the stewardship assets is included in the Deferred Maintenance section of the Required Supplementary Information.

NOTE 11. LIABILITIES NOT COVERED BY BUDGETARY RESOURCES

NOTE 12. DEBT

Net Change During Fiscal Year includes new borrowing, repayments and net change in accrued payables. Debt to the Treasury and to the Federal Financing Bank is for FRA direct loans to railroads, for FHWA direct loans under the Transportation Infrastructure Finance and Innovation Act (TIFIA), and for MARAD Title XI guaranteed loans.

NOTE 13. OTHER LIABILITIES

Accrued pay and benefits pertain to unpaid pay and benefits, and may be either current or noncurrent. Agency expenses for payments made under the Federal Employees Compensation Act (FECA) are forwarded to the Department of Labor (DOL). Funding for FECA is normally appropriated to agencies in the fiscal year two years subsequent to the actual FECA billing from DOL.

NOTE 14. GRANT ACCRUAL

Grant liabilities are accrued in two categories. The first category is grant related requests for payments that had been billed to an agency as of September 30, but had not yet been paid. The second category is for the grant related costs incurred, but not yet reported (IBNR). IBNR represents an estimate of amounts due to grantees for their expenditures made through September 30, for which payment requests have not been received from grantees as of September

30.

Grant accruals, by Operating Administration, at September 30, 2006 and 2005, are summarized as follows:

Environmental cleanup generally occurs under the Resource Conservation and Recovery Act of 1976 (RCRA), the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA or Superfund), or the Toxic Substances Control Act (TSCA). Environmental remediation includes the fuel storage tank program, fuels, solvents, industrial, and chemicals, and other environmental cleanup associated with normal operations or as a result of an accident. Cost estimates for environmental and disposal liabilities are not adjusted for inflation and are subject to revision as a result of changes in technology and environmental laws and regulations.

The current law requires all non-retention ships to be disposed of by the end of FY 2006. If an extension of this requirement is not granted and/or foreign scrapping is not available, then MARAD could realize a substantial increase in this unfunded environmental liabilities.

Note 17. Contingencies, Commitments, and Other Disclosures

Contingencies

Hurricane Disaster Relief. In September 2005, Hurricanes Katrina, Rita, and Wilma significantly affected certain sections with the states of Louisiana, Florida, Mississippi, Texas and Alabama.

Currently DOT in conjunction with other Federal entities is assessing the estimated financial impact of the affected areas. As of September 30, 2006, DOT obligated $1.83 billion of which $389 million will reimbursed to the DOT from FEMA.

During FY 2006 Congress, through Public Law 109-148, appropriated an additional $2.75 billion for bridge and road repair. These funds cover certain transit and travel costs used in evacuating and relocating displaced persons; a Ready Reserve Fleet of ships used for temporary housing, relief and recovery; airfield and terminal repairs; restoration of FAA facilities; pipeline inspection; emergency work to restore essential traffic and minimize damage, and protect remaining facilities and; repair and rebuild railroad infrastructure in a safe manner.

Legal Claims. As of September 30, 2006 and 2005, DOT's contingent liabilities for asserted and pending legal claims reasonably possible of loss were estimated at $27.9 million and $65.1 million, respectively. DOT does not have material amounts of known unasserted claims.

Grant Programs. FHWA pre-authorizes States to establish construction budgets without having received appropriations from Congress for such projects. FHWA does not guarantee the ultimate funding to the States for these “Advance Construction” projects and, accordingly, does not obligate any funds for these projects. When funding becomes available to FHWA, the States can then apply for reimbursement of costs that they have incurred on such project, at which time FHWA can accept or reject such request. For the fiscal year ended September, 2006 and 2005, FHWA has pre-authorized $45 billion and $40 billion, respectively, under these arrangements; however, no liability is reflected in the Highway Trust Fund financial statements at September, 2006 and 2005.

FTA executes Full Funding Grant Agreements (FFGAs) under its Capital Investment program (New Starts) authorizing transit authorities to establish project budgets and incur costs with their own funds in advance of annual appropriations by Congress. As of September 30, 2006 and 2005, approximately $1.4 billion and $2.2 billion respectively in Section 5309 New Starts funds has been committed under FFGAs, but not yet appropriated by Congress. However, no liability is reflected in the DOT financial statements at September 30, 2006, for these agreements.

Contract Options and Negotiations. As of September 30, 2006 and 2005, FAA had contract options of $3.35 billion and $10 billion, respectively. These contract options give FAA the unilateral right to purchase additional equipment or services or to extend the contract terms. Exercising this right would require the obligation of funds in future years.

Aviation Insurance Program. FAA is authorized to issue hull and liability insurance under the Aviation Insurance Program for air carrier operations for which commercial insurance is not available on reasonable terms and when continuation of U.S. flag commercial air service is necessary in the interest of air commerce, National security, and the U.S. foreign policy. FAA may issue (1) non-premium insurance, and (2) premium insurance for which a risk-based premium is charged to the air carrier, to the extent practical.

FAA maintains standby non-premium war-risk insurance policies for 37 air carriers having approximately 1,634 aircraft available for Defense or State Department charter operations.

On September 22, 2001, the Air Transportation Safety and System Stabilization Act (Public Law 107-42) expanded premium insurance program authority to permit insurance of domestic operations. Under this program, FAA initially provided third party liability war-risk insurance to

U.S. carriers whose coverage was cancelled following the terrorist attacks of September 11, 2001. Public Law 108-11 (and subsequent amendments) required FAA to extend policies in effect on July 19, 2002, until August 31, 2006. The Secretary of Transportation has extended coverage through December 31, 2006 as allowed by Public Law 108-11. It also mandated provision of hull loss and passenger and third party war risk liability insurance for those policies. During this year there were 75 FAA premium war-risk policies. Insured air carrier per occurrence limits for combined hull and liability coverage range from $100 million to $4 billion.

Current war risk coverage is intended as a temporary measure to provide insurance to qualifying carriers while allowing time for the commercial insurance market to stabilize. Premiums under this program are established by FAA and are based on the value of policy coverage limits and aircraft activity. However, airlines’ total charge for coverage is subject to a cap mandated by Congress. During FY 2006 and FY 2005, FAA recognized insurance premium revenue of $168.4 million and $157.5 million, respectively. Premiums are recognized as revenue on a straight-line basis over the period of coverage. Premium revenue is reported on the FAA’s Consolidated Statement of Net Cost, under “Regional and Center Operations and Other Programs.”

The maximum liability for both hull loss and liability, per occurrence, is $4 billion. No claims for losses were pending as of September 30, 2006, or 2005. In the past, FAA has insured a small number of air carrier operations and established a maximum liability for losing one aircraft. Since the inception of the Aviation Insurance Program dating back to 1951, only four claims, all involving minor dollar amounts, have been paid. Because of the unpredictable nature of war risk and the absence of historical claims experience on which to base an estimate, no reserve for insurance losses has been recorded.

Commitments

Grant Programs. FAA’s Airport Improvement Program provides grants for the planning and development of public-use airports that are included in the National Plan of Integrated Airport Systems. Eligible projects generally include improvements related to enhancing airport safety, capacity, security and environmental concerns. FAA's share of eligible costs for large and medium primary hub airports is 75 percent with the exception of noise program implementation, which is 80 percent. For remaining airports (small primary, relievers, and general aviation airports), FAA's share of eligible costs is 95 percent.

FAA has authority under 49 U.S.C. 47110(e) to issue letters of intent to enter into Airport Improvement Program grant agreements. FAA records an obligation when a grant is awarded. Through September 30, 2006, FAA issued letters of intent covering FY 1988 through FY 2020 totaling $5.3 billion. As of September 30, 2006, FAA had obligated $3.8 billion of this total amount leaving $1.5 billion unobligated.

Through September 30, 2005, FAA issued letters of intent covering FY 1988 through FY 2017 totaling $4.7 billion. As of September 30, 2005, FAA had obligated $3.6 billion of this total amount, leaving $1.1 billion unobligated.

NOTE 18. EARMARKED FUNDS

The Highway Trust Fund is comprised of the Highway Corpus Trust Fund and certain accounts of the Federal Highway Administration, Federal Motor Carrier Safety Administration, Federal Transit Administration, Federal Railroad Administration and the National Highway Traffic Safety Administration. The HTF was created in 1956 with the Highway Revenue Act of 1956 with the main objective of funding the construction of the Dwight D. Eisenhower System of Interstate and Defense Highways.

For FY 2007, the enacted budget of the United States has not been finalized. The President’s Budget of the United States for FY 2008 will not be published until February 2007, therefore, DOT is unable to confirm if differences exist between the information required by SFFAS No. 7 and the amounts described as “actual” for FY 2006 in the FY 2008 Budget of the United States. The information will be published on OMB’s Web site located at www.whitehouse.gov/omb.

Budget authority on the FY 2005 Combined Statement of Budgetary Resources includes expired funds of $2.8 million that are not presented in the Budget of the United States Government for the FAA. Also, obligations incurred on the FY 2005 Combined Statement of Budgetary Resources includes $77 million of expired funds and $762 million of certain reimbursable and revolving fund obligations incurred that are not presented in the Budget of the United States Government. As a result, DOT’s FY 2005 Combined Statement of Budgetary Resources differs from FY 2005 “actuals” reported in the appendix of the FY 2007 Budget of the United States Government.
