Why GAO Did This Study: 

Federal funding for highways is provided to the states mostly through 
a series of grant programs known as the Federal-Aid Highway Program, 
administered by the Department of Transportation’s (DOT) Federal 
Highway Administration (FHWA). In 2005, the Safe, Accountable, 
Flexible, Efficient Transportation Equity Act: A Legacy for Users 
(SAFETEA-LU) authorized $197.5 billion for the Federal-Aid Highway 
Program for fiscal years 2005 through 2009. The program operates on a “
user pay” system, wherein users contribute to the Highway Trust Fund 
through fuel taxes and other fees. The distribution of funding among 
the states has been a contentious issue. States that receive less than 
their highway users contribute are known as “donor” states and states 
that receive more than their highway users contribute are known as “
donee” states. 

GAO was asked to examine for the SAFETEA-LU period (1) how 
contributions to the Highway Trust Fund compared with the funding 
states received, (2) what provisions were used to address rate-of-
return issues across states, and (3) what additional factors affect 
the relationship between contributions to the Highway Trust Fund and 
the funding states receive. To conduct this review, GAO obtained and 
analyzed data from FHWA, reviewed FHWA and other reports, and 
interviewed FHWA and DOT officials. DOT reviewed a draft of this 
report and provided technical comments, which we incorporated as 
appropriate. 

What GAO Found: 

For the time period for which data are available, every state received 
as much or more funding for highway programs than they contributed to 
the Highway Account of the trust fund. This was possible because more 
funding was authorized and apportioned than was collected from the 
states and the fund needed to be augmented with general revenues (see 
map). If the percentage of funds states contributed to the total is 
compared with the percentage of funds states received (i.e., relative 
share), then 28 states received a relatively lower share and 22 states 
received a relatively higher share than they contributed. Thus, 
depending on the method of calculation, the same state can appear to 
be either a donor or donee state.

The Equity Bonus Program was used to address rate-of-return issues. It 
guaranteed a minimum return to states, providing them about $44 
billion. Nearly all states received Equity Bonus funding and about 
half received a significant increase, at least 25 percent, over their 
core funding. 

The infusion of general revenues into the Highway Trust Fund affects 
the relationship between funding and contributions, as a significant 
amount of highway funding is no longer provided by highway users. 
Since fiscal year 2008, Congress has transferred nearly $30 billion of 
general revenues to address shortfalls in the highway program when 
more funding was authorized than collected. Using rate of return as a 
major factor in determining highway funding poses challenges to 
introducing a performance and accountability orientation into the 
highway program; rate-of-return calculations in effect override other 
considerations to yield a largely predetermined outcome—that of 
returning revenues to their state of origin. Because of this 
challenge, funding surface transportation programs was placed on GAO’s 
High-Risk list.

June 30, 2010: 

The Honorable James L. Oberstar:
Chairman:
Committee on Transportation and Infrastructure:
House of Representatives: 

The Honorable Peter A. DeFazio:
Chairman:
Subcommittee on Highways and Transit:
Committee on Transportation and Infrastructure:
House of Representatives: 

Over decades, the nation has built a vast highway infrastructure that 
includes about 4 million miles of roads and 600,000 bridges, with the 
federal government providing a significant portion of funding for this 
system. In 2005, the Safe, Accountable, Flexible, Efficient 
Transportation Equity Act: A Legacy for Users (SAFETEA-LU) authorized 
over $190 billion for the Federal-Aid Highway Program for fiscal years 
2005 through 2009.[Footnote 1] The Highway Trust Fund has been the 
principal source of funding for this authorization. These funds are 
primarily collected from taxes on motor fuel and truck-related items 
and distributed to the states using a series of complex formulas that 
take into account a number of factors, including the estimated share 
of taxes highway users in each state contributed to the fund. Because 
the Federal-Aid Highway Program has operated on a "user pay" system, 
wherein users contribute to the building and upkeep of the system, 
states have taken a strong interest in the rate of return on 
contributions. Thus, how the funding has been distributed among states 
has been contentious. States that receive less than the estimated 
contributions of their highway users are known as "donor" states. 
States that receive more than the estimated contributions of their 
highway users are known as "donee" states. 

To better understand the relationship between contributions to the 
Highway Trust Fund and the amount of federal funding states received, 
at your request, we examined: 

* The amount of revenue contributed to the Highway Trust Fund Highway 
Account compared with the funding states received during the SAFETEA-
LU period;[Footnote 2] 

* The provisions in place during the SAFETEA-LU period to address rate-
of-return issues across states, and how they affected the highway 
funding states received; and: 

* Additional factors that affected the relationship between 
contributions to the Highway Trust Fund and the funding states receive. 

To determine how the amount of revenue contributed compared to funding 
states received, we obtained and analyzed Federal Highway 
Administration (FHWA) data including FHWA estimates of payments made 
into the Highway Account of the Highway Trust Fund, by state, and the 
actual total apportionments and allocations states received during the 
SAFETEA-LU period. Because different methods of calculating a rate of 
return can provide different results, we analyzed four different 
scenarios to address this question. To determine provisions in place 
to address rate of return issues and their effect on funding, we 
obtained and analyzed FHWA data on state funding during the SAFETEA-LU 
period, and determined the extent to which rate of return provisions 
increased state funding. To determine additional factors that affect 
the relationship between contribution to the Highway Trust Fund and 
states' funding, we reviewed FHWA, GAO and other reports, including 
our body of work on surface transportation financing and the Highway 
Trust Fund. For each objective, we also reviewed DOT and FHWA reports 
and interviewed DOT and FHWA officials. We also obtained additional 
information from FHWA on the steps taken to ensure data reliability 
and determined the data were sufficiently reliable for our purposes. 

We conducted this performance audit from April 2010 through June 2010 
in accordance with generally accepted government auditing standards. 
Those standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe 
that the evidence obtained provides a reasonable basis for our 
findings and conclusions based on our audit objectives. Appendix I 
provides more detailed information on our scope and methodology. 
Appendix II discusses how FHWA determined state contributions to the 
Highway Account of the Highway Trust Fund during SAFETEA-LU. 

Background: 

Federal funding for highways is provided to the states mostly through 
a series of grant programs collectively known as the Federal-Aid 
Highway Program. Periodically, Congress enacts multiyear legislation 
that authorizes the nation's surface transportation programs. In 2005, 
Congress enacted SAFETEA-LU, which authorized $197.5 billion for the 
Federal-Aid Highway Program from fiscal years 2005 through 2009. In a 
joint federal-state partnership the FHWA, within the Department of 
Transportation (DOT), administers the Federal-Aid Highway Program and 
distributes most funds to the states through annual apportionments 
established by statutory formulas.[Footnote 3] Once FHWA apportions 
these funds, the funds are available for states to obligate for 
construction, reconstruction, and improvement of highways and bridges 
on eligible federal-aid highway routes, as well as for other purposes 
authorized in law. The amount of federal funding made available for 
highways was substantial--from $34.4 to $43.0 billion per year for 
fiscal years 2005 through 2009. 

The Highway Trust Fund was instituted by Congress in 1956 to construct 
the Interstate Highway System, which is currently 47,000 miles in 
length. The Highway Trust Fund holds certain excise taxes collected on 
motor fuels and truck-related taxes, including taxes on gasoline, 
diesel fuel, gasohol, and other fuels; truck tires and truck sales; 
and heavy vehicle use. In 1983, the fund was divided into the Highway 
Account and the Mass Transit Account.[Footnote 4] More than 80 percent 
of the total fund is the Highway Account, including a majority of the 
fuel taxes as well as all truck-related taxes (see figure 1).

Most Highway Account funds (about 83 percent) were apportioned to 
states across 13 formula programs during the 4 years of the SAFETEA-LU 
period for which data are available. Included among these 13 programs 
are 6 "core" highway programs (see table 1).

[End of table] 

In addition to formula programs, for the time during the SAFETEA-LU 
period for which final data are available: 

* Congress directly allocated about 8 percent of Highway Account funds 
to state departments of transportation through congressionally 
directed High Priority Projects. 

* The remaining funds, about 9 percent of the total, represent dozens 
of other authorized programs allocated to state DOTs, congressionally 
directed projects other than High Priority Projects, administrative 
expenses and funding provided to states by other DOT agencies such as 
the National Highway Traffic Safety Administration and Federal Motor 
Carrier Safety Administration (see figure 2).

Projects, and All Other Programs, FY 2005-2008:

High priority projects: 7.5%; 
All other programs: 9.4%.

Note: Comparable data for FY2009 are not yet available. Apportioned 
programs funded through the Highway Account include the following: 
Interstate Maintenance, National Highway System, Surface 
Transportation, Congestion Mitigation and Air Quality, Highway Bridge, 
Appalachian Development Highway System, Coordinated Border 
Infrastructure, Highway Safety Improvement, metropolitan planning, 
Rail-Highway Safety, Recreational Trails, Safe Routes to Schools, and 
the Equity Bonus. 

[End of figure] 

Some of the apportioned programs use states' contributions to the 
Highway Account of the Highway Trust Fund as a factor in determining 
program funding levels for each state.[Footnote 5] Because the 
Department of Treasury (Treasury) collects fuel taxes from a small 
number of corporations located in a relatively small number of places-
-not from states--FHWA has to estimate the fuel tax contributions made 
to the fund by users in each state. Likewise, FHWA must estimate the 
state of origin of various truck taxes. FHWA calculates motor fuel- 
related contributions based on estimates of the gallons of fuel used 
on highways in each state. To do so, FHWA relies on data gathered from 
state revenue agencies and summary tax data available from Treasury as 
part of the estimation process (see appendix II). Because the 
collection and estimation process takes place over several years (see 
figure 3), the data used to calculate the formula are 2 years old. For 
example, the data used to apportion funding to states in fiscal year 
2009 were based on estimated collections attributable to each state in 
fiscal year 2007.

[End of figure] 

By the early 1980s, construction of the Interstate Highway System was 
nearing completion, and a larger portion of the funds from the Highway 
Trust Fund were being authorized for non-Interstate programs. The 
Surface Transportation Assistance Act of 1982 provided, for the first 
time, that each state would for certain programs receive a "minimum 
allocation" of 85 percent of its share of estimated tax payments to 
the Highway Account of the Highway Trust Fund. This approach was 
largely retained when Congress reauthorized the program in 1987. The 
Intermodal Surface and Transportation Efficiency Act of 1991 (ISTEA) 
raised the minimum allocation to 90 percent. The Transportation Equity 
Act for the 21st Century (TEA-21) of 1997 guaranteed each state a 
specific share of the total program (defined as all apportioned 
programs plus High Priority Projects), a minimum 90.5 percent share of 
contributions. It also introduced rate-of-return considerations into 
funds states received for the Interstate Maintenance, National Highway 
System, and Surface Transportation Programs. In 2005, Congress 
implemented through SAFETEA-LU the Equity Bonus Program that was 
designed to bring all states up to a guaranteed rate of return of 92 
percent by fiscal year 2008. 

Rate of Return Varies Depending on the Calculation Used, but States 
Received More Funding from the Highway Trust Fund Than Their Users 
Contributed: 

States Received as Much or More Funding Than Their Highway Users 
Contributed: 

For the time period for which final data are available, fiscal years 
2005 through 2008, our analysis shows that every state but one 
received more funding for highway programs than users contributed to 
the Highway Account (see figure 4). The only exception, Texas, 
received about $1.00 (99.7 cents) for each dollar contributed. Among 
other states, this ranged from a low of $1.02 for both Arizona and 
Indiana to a high of $5.63 for the District of Columbia. In addition, 
all states, including Texas, received more in funding than their 
highway users contributed during both fiscal years 2007 and 2008. 
[Footnote 6] In effect, almost every state was a donee state during 
the first 4 years of SAFETEA-LU. This occurred because overall, more 
funding was authorized and apportioned than was collected from highway 
users. The account was supplemented by general funds from the 
Treasury.[Footnote 7]

Our rate-of-return analysis has two notable features: 

* It compares funding states received from the Highway Trust Fund 
Highway Account with the dollars estimated to be have been collected 
in each state and contributed by each state's highway users into the 
Highway Account in that same year. For example, for fiscal year 2008, 
it compares the highway funds states received in fiscal year 2008 with 
the amount collected and contributed in that fiscal year--data that 
did not become available until December 2009. Because of the 2-year 
lag (see figure 3), fiscal year 2008 is the latest year for which 
these data are available. Thus, the final year of the original SAFETEA-
LU authorization period, fiscal year 2009, is not included. 

* Unlike other calculations used to apportion certain funds discussed 
further in this report, this analysis includes all funding provided to 
the states from the Highway Account, including (1) funds apportioned 
by formula, (2) High Priority Projects, and (3) other authorized 
programs, including safety program funding provided to states by other 
DOT agencies such as the National Highway Traffic Safety 
Administration and Federal Motor Carrier Safety Administration (see 
figure 2 for a breakdown of these funds). 

Rate of Return Varies, as Other Methods of Calculating State's Rate of 
Return Provide Different Results: 

Using the above methodology, our analysis shows that states generally 
received more than their highway users contributed. However, other 
calculations, as described below, provide different results. Because 
there are different methods of calculating a rate of return, and the 
method used affects the results, confusion can result over whether a 
state is a donor or donee. A state can appear to be donor using one 
type of calculation and a donee using a different type. 

A second way to calculate rate of return is to apply the same dollar 
return calculation method, but use contribution data that are 
available at the time funds are apportioned to the states. This 
calculation method indicates that all states were donees. The data 
used to calculate the rate of return per dollar contributed differs 
from our preceding analysis in two ways: 

* As shown in figure 3, it uses 2-year-old data on contributions for 
apportionments, due to the time lag between when the Treasury collects 
fuel and truck excise taxes and funds are apportioned.[Footnote 8] 

* It uses a subset of Federal-Aid Highway programs including both 
programs apportioned to states by formula and High Priority Projects. 
However, it does not include other allocated highway programs or other 
funding states receive from programs other DOT agencies such as the 
National Highway Traffic Safety Administration and Federal Motor 
Carrier Safety Administration (see figure 2).[Footnote 9] 

Using this approach every state received more in funding from the 
Highway Account of the Highway Trust Fund than its users contributed 
for the SAFETEA-LU period. The rate of return ranged from a low of 
$1.04 per dollar for 16 states, including Texas, to a high of $5.26 
per dollar for the District of Columbia, as shown in figure 5. This 
calculation results in states generally having a lower dollar rate of 
return than our calculation using same-year data (see figure 4).

Note: Calculations compare the amount each state received through the 
apportioned programs and High Priority Projects in FY2005-2009 with 
each state's highway users' estimated contribution into the Highway 
Account in the corresponding revenue years (FY2003-2007). 

[End of figure] 

A third calculation, based on a state's "relative share"--the amount a 
state receives relative to other states instead of an absolute, dollar 
rate of return--results in both donor and donee states. Congress 
defined this method in SAFETEA-LU as the one FHWA uses for the 
calculating rates of return for the purpose of apportioning highway 
funding to the states.[Footnote 10] In order to calculate this rate of 
return, FHWA must determine what proportion of the total national 
contributions came from highway users in each state. The state's share 
of contributions into the Highway Account of the Highway Trust Fund is 
then used to calculate a relative rate of return--how the proportion 
of each state's contribution compares to the proportion of funds the 
state received. A comparison of the relative rate of return on states' 
contributions showed 28 donor states, receiving less than 100 percent 
relative rate of return, and 23 states as donees receiving a more than 
a 100 percent relative rate of return (see figure 6). States' relative 
rates of return ranged from a low of 91.3 percent for 12 states to a 
high of 461 percent for the District of Columbia. Like the return per 
dollar analysis in figure 5, this calculation includes only formula 
funds and High Priority Projects allocated to states, and excludes 
other DOT authorized programs allocated to states (see figure 2). The 
difference between a state's absolute and relative rate of return can 
create confusion because the share calculation is sometimes mistakenly 
referred to as "cents on the dollar."

Note: Calculations compare the share of the total funding each state 
received through the apportioned programs and High Priority Projects 
in FY2005-2009 with the estimated share of the national total that 
each state contributed into the Highway Account in the corresponding 
revenue years (FY2003-2007). 

[End of figure] 

Using the relative share method of calculation will result in some 
states being "winners" and other states being "losers." If one state 
receives a higher proportion of highway funds than its highway users 
contributed, another state must receive a lower proportion than it 
contributed. The only way to avoid this is for every state to get back 
exactly the same proportion that it contributed, which is impractical 
because estimated state contribution shares are not known until 2 
years after the apportionments and allocations. Furthermore, because 
more funding has recently been apportioned and allocated from the 
Highway Account than is being contributed by highway users, a state 
can receive more than it contributes to the Highway Trust Fund Highway 
Account, making it a donee under its rate of return per dollar, but a 
donor under its relative share rate of return. 

California provides a useful example of this. From fiscal year 2005 
through 2008, using same year contributions and funding across all 
Highway Trust Fund Highway Account allocations and apportionments, 
California received $1.16 for each dollar contributed. This analysis 
shows California as a donee state (see table 2). Alternatively, when 
calculating a dollar rate of return over the full SAFETEA-LU period 
(fiscal years 2005 through 2009) using state contribution estimates 
available at the time of apportionment (fiscal year 2003 through 2007 
(as shown in figure 3) and including only programs covered in rate-of- 
return adjustments, California remains a donee state, but received 
$1.04 for each dollar contributed. In contrast, using the relative 
share approach for the fiscal year 2005 through 2009 period, 
California received 91 percent of the share its highway users 
contributed in federal highway-related taxes, which would make it a 
donor state.

[End of table] 

A fourth method for calculating a state's rate of return is possible, 
but not normally calculated by FHWA. It involves evaluating the 
relative share as described above, but using the same year comparison 
data. Again, because of the time lag required to estimate state 
highway user contributions to the Highway Account, such analysis is 
possible only 2 years after FHWA calculates apportionments for states. 
Our analysis using this approach results in yet another set of rate of 
return answers. For example, using available data from fiscal years 
2005 to 2008, the relative rate of return for California becomes 97 
percent, rather than 91 percent. When this analysis is applied to all 
states, a state may change its donor/donee status. For example, 
Minnesota, Nebraska, and Oklahoma appear both as donor and donee 
states, depending on the calculation method. This comparison of the 
relative rate of return on states' contributions showed 27 states 
receiving less than 100 percent relative rate of return, and 24 states 
as receiving a more than a 100 percent relative rate of return. Table 
3 shows the results for all four methods described and the wide 
variation of states' rate of return based on the method used.

Equity Bonus Provisions in SAFETEA-LU Addressed Rate of Return among 
States: 

Since 1982, Congress has attempted to address states' concerns 
regarding the rate of return on highway users' contribution to the 
Highway Trust Fund. In 2005, Congress enacted in SAFETEA-LU the Equity 
Bonus Program, designed to bring all states up to a "guaranteed" rate 
of return.[Footnote 11] The Equity Bonus is calculated from a subset 
of Federal-Aid Highway programs, which include 12 formula programs, 
plus High Priority Projects designated by Congress.[Footnote 12] In 
brief, since SAFETEA-LU, the Equity Bonus allocates sufficient funds 
to ensure that each state receives a minimum return of 90.5 percent 
for fiscal years 2005-2006, 91.5 percent for fiscal year 2007, and 92 
percent for fiscal years 2008-2009 for the included programs. The 
Equity Bonus provides more funds to states than any other individual 
Federal-Aid Highway formula program. Over SAFETEA-LU's initial 5-year 
authorization period, the Equity Bonus provided $44 billion to the 
states, while the second largest formula program, the Surface 
Transportation Program, provided $32.5 billion. Each year about $2.6 
billion stay as Equity Bonus program funds and may be used for any 
purpose eligible under the Surface Transportation Program. Any 
additional Equity Bonus funds are added to the apportionments of the 
six "core" federal-aid highway formula programs: the Interstate 
Maintenance, National Highway System, Surface Transportation, 
Congestion Mitigation and Air Quality, Highway Bridge and the Highway 
Safety Improvement programs. States are frequently able to transfer a 
portion of their funds among the core programs, making funding of core 
programs less critical than it might be. 

States may qualify for Equity Bonus funding by meeting any of three 
criteria (see figure 7). A state that meets more than one criterion 
receives funding under whichever provision provides it the greatest 
amount of funding. FHWA conducts Equity Bonus calculations annually. 

Figure 7: Equity Bonus Program Criteria: 

[Refer to PDF for image: illustration] 

Equity Bonus Program provisions: 
All States may qualify under any one of three provisions for Equity 
Bonus Program funding: 

1) Guaranteed relative rate of return: 
All states were guaranteed a specific rate of return of their share of 
estimated contributions to the Highway Account of the Highway Trust 
Fund. 
Or: 
2) Guaranteed increase over Transportation Equity Act for the 21st 
Century (TEA-21) funding: 
All states are guaranteed an amount greater than the average amount 
they received under the authorization measure that preceded SAFTEA-
LU -- TEA-21 (1998-2004). 
Or: 
3) States meet certain “hold harmless” qualifying criteria: 
A state is guaranteed a share of apportionments and High Priority 
Projects at least equal to its share of total apportionments and High 
Priority Projects under TEA-21, if it had any of 5 qualifying 
characteristics at the time SAFETEA-LU was enacted: 

Characteristic: Population density; 
Qualifying criteria: Less than 40 people per square mile and federal 
land ownership in the state exceeds 1.25 percent of total state 
acreage; 
Qualifying states: 11. 

Characteristic: Population; 
Qualifying criteria: Under 1 million; 
Qualifying states: 8. 

Characteristic: Median income; 
Qualifying criteria: Less than $35,000; 
Qualifying states: 10. 

Characteristic: Highway fatality rate; 
Qualifying criteria: Over 1 per 100 million Interstate Highway vehicle 
miles traveled; 
Qualifying states: 18. 

Characteristic: Indexed state motorfuels excise tax; 
Qualifying criteria: Over 150 percent of the federal motor fuels 
excise tax rate; 
Qualifying states: 1. 

Source: FHWA. 

Note: States may have more than one qualifying characteristic under 
the hold harmless provision; therefore, the qualifying state column is 
not additive. 

[End of figure] 

For the first criterion, the guaranteed relative rate of return, for 
fiscal year 2005 all states were guaranteed at least 90.5 percent of 
their share of estimated contributions. The guaranteed rate increased 
over time, rising to 92 percent in fiscal year 2009. The second 
criterion, the guaranteed increase over average annual Transportation 
Equity Act for the 21st Century (TEA-21) funding, also varied by year, 
rising from 117 percent in fiscal year 2005 to 121 percent for fiscal 
year 2009. The number of states qualifying under the first two 
provisions can vary from year to year. For the third criterion, a 
guarantee to "hold harmless" states that had certain qualifying 
characteristics at the time SAFETEA-LU was enacted, 27 states had at 
least one of these characteristics. A number of these states had more 
than one of these characteristics. 

Forty-seven states received Equity Bonus funding every year during the 
SAFETEA-LU period. However, the District of Columbia, Rhode Island, 
and Vermont each had at least 1 year where they did not receive Equity 
Bonus funding because they did not need it to reach the funding level 
specified under the three provisions. Maine was the only state that 
did not receive an Equity Bonus in any year. Half of all states 
received a significant increase in their overall Federal-Aid Highway 
Program-at least 25 percent over their core funding. Each state's 
percent increase in its overall funding total for apportioned programs 
and High Priority Projects for fiscal years 2005 through 2009 due to 
Equity Bonus funding is shown in figure 8.

Adding General Revenues into the Trust Fund and Other Challenges Raise 
Questions about Relying on States' Rate-of-Return to Distribute 
Federal Highway Funds: 

Additional factors affect the relationship between contributions to 
the Highway Trust Fund and the funding states receive. These include 
(1) the infusion of significant amounts of general revenues into the 
Highway Trust Fund, (2) the challenge of factoring performance and 
accountability for results into transportation investment decisions, 
and (3) the long-term sustainability of existing mechanisms and the 
challenges associated with developing new approaches to funding the 
nation's transportation system. 

First, the infusion of significant amounts of general revenues into 
the Highway Trust Fund Highway Account breaks the link between highway 
taxes and highway funding. The rate-of-return approach was designed to 
ensure that, consistent with the user pay system, wherein the costs of 
building and maintaining the system are borne by those who benefit, 
users receive a fair return on their investment to the extent 
possible. However, in fiscal year 2008 the Highway Trust Fund held 
insufficient amounts to sustain the authorized level of funding and, 
partly as a result, we placed it on our list of high-risk programs. 
[Footnote 13] To cover the shortfall, from fiscal years 2008 through 
2010 Congress transferred a total of $34.5 billion in additional 
general revenues into the Highway Trust Fund, including $29.7 billion 
into the Highway Account. This means that, to a large extent, funding 
has shifted away from the contributions of highway users, breaking the 
link between highway taxes paid and benefits received by users. 
Furthermore, the infusion of a significant amount of general fund 
revenues complicates rate-of-return analysis because the current 
method of calculating contributions does not account for states' 
general revenue contributions. For many states, the share of Highway 
Trust Fund contributions and general revenue contributions are 
different, therefore state-based contributions to all the funding in 
the Trust Fund are no longer clear.[Footnote 14] In addition, since 
March 2009, the American Recovery and Reinvestment Act of 2009 
apportioned an additional $26.7 billion to the states for highways--a 
significant augmentation of federal highway spending that was funded 
with general revenues. 

Second, using rate of return as a major factor in determining federal 
highway funding levels is at odds with reexamining and restructuring 
federal surface transportation programs so that performance and 
accountability for results is factored into transportation investment 
decisions. As we have reported, for many surface transportation 
programs, goals are numerous and conflicting, and the federal role in 
achieving the goals is not clear. Many of these programs have no 
relationship to the performance of either the transportation system or 
of the grantees receiving federal funds and do not use the best tools 
and approaches to ensure effective investment decisions.[Footnote 15] 
Our previous work has outlined the need to create well defined goals 
based on identified areas of federal interest and a clearly defined 
federal role in relation to other levels of government.[Footnote 16] 
We have suggested that where the federal interest is less evident, 
state and local governments could assume more responsibility, and some 
functions could potentially be assumed by the states or other levels 
of government.[Footnote 17] Furthermore, incorporating performance and 
accountability for results into transportation funding decisions is 
critical to improving results. However the current approach presents 
challenges. The Federal-Aid Highway program, in particular, 
distributes funding through a complicated process in which the 
underlying data and factors are ultimately not meaningful because they 
are overridden by other provisions designed to yield a largely 
predetermined outcome--that of returning revenues to their state of 
origin.[Footnote 18] Moreover, once the funds are apportioned, states 
have considerable flexibility to reallocate them among highway and 
transit programs.[Footnote 19] As we have reported, this flexibility, 
coupled with a rate-of-return orientation, essentially means that the 
Federal-Aid Highway program functions, to some extent, as a cash 
transfer, general purpose grant program.[Footnote 20] This approach 
poses considerable challenges to introducing performance orientation 
and accountability for results into highway investment decisions. For 
three highway programs that were designed to meet national and 
regional transportation priorities, we have recommended that Congress 
consider a competitive, criteria-based process for distributing 
federal funds.[Footnote 21] 

Finally, using rate of return as a major factor in determining federal 
highway funding levels poses problems because funding the nation's 
transportation system through taxes on motor vehicle fuels is likely 
to be unsustainable in the longer term. Receipts for the Highway Trust 
Fund derived from motor fuel taxes have declined in purchasing power, 
in part because the federal gasoline tax rate has not increased since 
1993. In fiscal year 2008 (the last year for which data are available) 
total contributions to the Highway Account of the Highway Trust Fund 
decreased by more than $3.5 billion from fiscal year 2007, the first 
year of decrease during the SAFETEA-LU period. Over the long term, 
vehicles will become more fuel efficient and increasingly run on 
alternative fuels--for example, higher fuel economy standards were 
enacted in 2010. As such, fuel taxes may not be a sustainable source 
of transportation funding.[Footnote 22] Furthermore, transportation 
experts have noted that transportation policy needs to recognize 
emerging national and global challenges, such as reducing the nation's 
dependence on imported fuel and minimizing the effect of 
transportation systems on the global climate.[Footnote 23] A fund that 
relies on increasing the use of motor fuels to remain solvent might 
not be compatible with the strategies that may be required to address 
these challenges. 

In the near future, policy discussions will need to consider what the 
most adequate and appropriate transportation financing systems will be 
and whether or not the current system continues to make sense. The 
National Surface Transportation Infrastructure Financing Commission-- 
created by SAFETEA-LU to, among other things, explore alternative 
funding mechanisms for surface transportation--identified and 
evaluated numerous revenue sources for surface transportation programs 
in its February 2009 report including alternative approaches to the 
fuel tax, mileage-based user fees, and freight-related charges. 
[Footnote 24] The report also discussed using general revenues to 
finance transportation investment but concluded that it was a weak 
option in terms of economic efficiency and other factors, and 
recommended that new sources of revenue to support transportation be 
explored. These new sources of revenue may or may not lend themselves 
to using a rate of return approach.

Appendix I: Objectives, Scope, and Methodology: 

To determine the amount of revenue states contributed to the Highway 
Trust Fund Highway Account compared with the funding they received 
during the Safe, Accountable, Flexible, Efficient Transportation 
Equity Act: A Legacy for Users (SAFETEA-LU) period, we completed four 
analyses using Federal Highway Administration (FHWA) data. We met with 
FHWA and other DOT officials to discuss availability of data and 
appropriate methodologies. We used FHWA estimates of payments made 
into the Highway Account of the Highway Trust Fund, by state, and the 
actual total apportionments and allocations made from the fund, by 
state. This is sometimes referred to as a "dollar-in, dollar-out" 
analysis. Because the contribution data takes about 2 years for FHWA 
to compile, for our analyses we used data for 4 of 5 years of the 
SAFETEA-LU period, 2005 through 2008, as data for 2009 were not yet 
available. The source data are published annually in Highway 
Statistics and commonly referred to as table FE-221, titled 
"Comparison of Federal Highway Trust Fund Highway Account Receipts 
Attributable to the States and Federal-Aid Apportionments and 
Allocations from the Highway Account." FHWA officials confirmed that 
it contains the best estimate of state contributions and also contains 
the total appropriations and allocations received by states from the 
Highway Account of the fund. We did not independently review FHWA's 
process for estimating state highway users' contributions into the 
Highway Trust Fund. However, we have reviewed this process in the 
past, and FHWA officials verified that they have made changes to the 
process as a result of that review.[Footnote 25] In addition, we did 
not attribute any prior balances in the Highway Trust Fund back to 
states of origin because these funds are not directly tied to any 
specific year or state. We only examined the fiscal year 2005 through 
2008 period; other time periods could provide a different result. 

We performed alternative analyses to demonstrate that different 
methodologies provide different answers to the question of how the 
contributions of states' highway users compared to the funding states 
received. Using the same data as described above, we performed a 
"relative share" analysis, which compared each state's estimated 
proportion of the total contributions to the Highway Account to each 
state's proportion of total Federal-Aid Highway funding. We also 
examined how states fared using FHWA's approach for determining the 
Equity Bonus Program funding apportionments. We performed this 
analysis to show the outcomes for states based on the information 
available at the time the Equity Bonus program apportionments are 
made. The Equity Bonus program amounts are calculated using the 
statutory formulas for a subset of Federal-Aid Highway Programs. These 
include all programs apportioned by formula plus the allocated High 
Priority Projects. FHWA uses the most current contribution data 
available at the time it does its estimates. However, as explained 
above, the time lag for developing this data is about 2 years. 
Therefore, we applied the contribution data for 2003 through 2007 to 
the funding data for 2005 through 2009, the full SAFETEA-LU period. 
For these data, we (1) analyzed the total estimated contributions by 
state divided by the total funding received by state--the dollar-in, 
dollar out methodology--and (2) a comparison of the share of 
contributions to share of payments received for each state. We 
obtained data from the FHWA Office of Budget for the analysis of state 
dollar-in dollar-out outcomes, and state relative share data for the 
Equity Bonus Program. We completed our analyses across the total years 
of the SAFETEA-LU period, 2005 through 2009. We interviewed FHWA 
officials and obtained additional information from FHWA on the steps 
taken to ensure data reliability and determined the data were 
sufficiently reliable for the purposes of this report: 

To determine the provisions in place during the SAFETEA-LU period to 
address rate-of-return issues across states and how they affected the 
highway funding states received, we reviewed SAFETEA-LU legislation, 
reports by the Congressional Research Service (CRS) and FHWA. We also 
spoke with FHWA and DOT officials to get their perspectives. We also 
conducted an analysis of FHWA data on the Equity Bonus Program 
provisions which were created explicitly to address the rate-of-return 
issues across states. Our analysis compared funding levels distributed 
to states via apportionment programs and High Priority Projects before 
and after Equity Bonus Program provisions were applied, and calculated 
the percentage increase each state received as a result of the Equity 
Bonus. 

To determine what additional factors affected the relationship between 
contributions to the Highway Trust Fund and the funding states 
receive, we reviewed GAO reports on federal surface transportation 
programs and the Highway Trust Fund, as well as CRS and FHWA reports, 
and the report of the National Surface Transportation Infrastructure 
Financing Commission. In addition, we reviewed FHWA data on the status 
of the Highway Account of the Highway Trust Fund. We also met with 
officials from Department of Transportation's Office of Budget and 
Programs and FHWA to obtain their perspectives on the issue. 

[End of section] 

Appendix II: FHWA Estimates Contributions to the Highway Trust Fund: 

Currently, FHWA estimates state-based contributions to the Highway 
Account of the Highway Trust Fund through a process that includes data 
collection, adjustment, verification, and final calculation of the 
states' highway users' contributions. FHWA first collects monthly 
motor fuel use data and related annual state tax data from state 
departments of revenue. FHWA then adjusts states' data by applying its 
own models using federal and other data to establish data consistency 
among the states. FHWA provides feedback to the states on these 
adjustments and estimates through FHWA Division Offices. Finally, FHWA 
applies each state's highway users' estimated share of highway fuel 
usage to total taxes collected nationally to arrive at a state's 
contribution to the Highway Trust Fund. We did not assess the 
effectiveness of FHWA's process for estimating the amount of tax funds 
attributed to each state for this report.[Footnote 26] 

According to FHWA officials, data from state revenue agencies is more 
reliable and comprehensive than vehicle miles traveled data, so FHWA 
uses state tax information to calculate state contributions. States 
submit regular reports to FHWA, including a monthly report on motor- 
fuel consumption due 90 days after month's end, and an annual motor- 
fuel tax receipts report due 90 days after calendar year's end. States 
have a wide variety of fuel tracking and reporting methods, so FHWA 
adjusts the data to achieve uniformity. FHWA analyses and adjusts fuel 
usage data, such as off-highway use related to agriculture, 
construction, industrial, marine, rail, aviation and off-road 
recreational usage. It also analyzes and adjusts use data based on 
public-sector use, including federal civilian, and state, county, and 
municipal use. 

FHWA headquarters and Division Offices also work together to 
communicate with state departments of revenue during the attribution 
estimation process.[Footnote 27] According to FHWA officials, each 
year FHWA headquarters issues a memo prompting its Division Offices to 
have each state conduct a final review of the motor fuel gallons 
reported by their respective states. FHWA division offices also are 
required to assess their state's motor fuel use and highway tax 
receipt process at least once every 3 years to determine if states are 
complying with FHWA guidance on motor fuel data collection. 

Once the data are finalized, FHWA applies each state's estimated share 
of taxed highway fuel use to the total taxes collected to arrive at a 
state's contribution in the following manner. Finalized estimations of 
gallons of fuel used on highways in two categories--gasoline and 
special fuels--allow FHWA to calculate each state's share of the total 
on-highway fuel usage. The shares of fuel use for each state are 
applied to the total amount of taxes collected by the Department of 
the Treasury in each of the 10 categories of highway excise tax. The 
state's gasoline share is applied to the gasoline and gasohol taxes, 
and the state's special fuels share, which includes diesel fuel, is 
applied to all other taxes, including truck taxes.[Footnote 28]

[1] Additional spending has been authorized since 2009, most recent 
extension expires December 31, 2010. (Pub.L. 111-147, March 18, 2010, 
124 Stat 71.) 

[2] The original period of SAFETEA-LU was fiscal year 2005 through 
fiscal year 2009. 

[3] Our discussion of states in this report includes the District of 
Columbia. 

[4] The Leaking Underground Storage Tank Trust Fund was added in 1986. 

[5] These programs include the Interstate Maintenance, Surface 
Transportation, and Equity Bonus programs. 

[6] If the existing trend continued into 2009, Texas may also be a 
donee state for the 5-year SAFTEA-LU period. 

[7] As states received more in funding than highway users contributed 
in taxes, both an existing balance in the Highway Account was drawn 
down, and the account was supplemented by other funds from the 
Treasury. We did not attempt to estimate what residual contribution in 
these prior balances is theoretically attributable to a state in our 
analysis. 

[8] Apportionments are made on the first day of the fiscal year. At 
that time, tax collections for the year are not known. Likewise, tax 
collections for the year that ended the day before the apportionments 
are not known. 

[9] This set of programs is used in the calculation of Equity Bonus 
Program funding, discussed later in this report. 

[10] These FHWA calculations are part of the Equity Bonus Program, 
discussed later in the report.

[14] This also complicates longer-term, historical analyses of state- 
based rate of return for the Highway Account. During certain periods 
general funds from the Treasury have been added to the Highway Trust 
Fund in the form of interest payments on the Highway Trust Fund 
balance. Conversely, in the past fuel taxes have also been used for 
deficit reduction.

[26] We last reviewed this process in 2000. At that time, we made a 
number of recommendations to improve the process and FHWA instituted 
improvements based on these recommendations. See GAO, Highway Funding:

[27] FHWA maintains a division office in each of the states and the 
District of Columbia. 

[28] Special fuels principally includes diesel fuel but also includes 
very small amounts of highway uses of liquefied petroleum gas, 
kerosene, natural gas, and biodiesel.
