Bureau of Prisons
Methods for Cost Estimation Largely Reflect Best Practices, but Quantifying Risks Would Enhance Decision Making Gao ID: GAO-10-94 November 10, 2009The Department of Justice's (DOJ) Federal Bureau of Prisons (BOP) is responsible for the custody and care of about 209,000 federal inmates--a population which has grown by 44 percent over the last decade. In fiscal years 2008 and 2009, the President requested additional funding for BOP because costs for key operations were at risk of exceeding appropriated funding levels. Government Accountability Office (GAO) was congressionally directed to examine (1) how BOP estimates costs when developing its annual budget request to DOJ; (2) the extent to which BOP's methods for estimating costs follow established best practices; and (3) the extent to which BOP's costs for key operations exceeded requested funding levels identified in the President's budget in recent years, and how this has affected BOP's ability to manage its growing inmate population. In conducting our work, GAO analyzed BOP budget documents, interviewed BOP and DOJ officials, and compared BOP's cost estimation documentation to criteria in GAO's Cost Estimating and Assessment Guide.
BOP uses three general steps to estimate costs for its annual budget submission: (1) estimating cost increases to maintain service levels, such as inmate medical care and utilities; (2) projecting inmate population changes for the budget year and for several years into the future using a modeling program that incorporates data on the current inmate population and estimated incoming population and associated sentences; and (3) estimating costs to both provide additional capacity to house projected inmate population growth and implement new programs, such as activating new prisons. BOP's methods for cost estimation largely reflect best practices outlined in GAO's Cost Estimating and Assessment Guide. BOP followed a well-defined process for developing a mostly comprehensive, well documented, accurate, and credible cost estimate for fiscal year 2008. For example, BOP used relevant historical cost data and considered adjustments for general inflation when estimating costs for its budget request to DOJ. Moreover, BOP's methods for projecting inmate population changes were accurate, on average, to within 1 percent of the actual inmate population growth from fiscal year 1999 to August 2009. Still, BOP could strengthen its methods in two ways. First, BOP has not quantified the level of confidence associated with its cost estimate. While not required by the Office of Management and Budget or DOJ, conducting an uncertainty analysis of this kind is a best practice. By providing the results of such analysis to DOJ, BOP officials could share advance information on the probability and associated risks of operating expenses exceeding enacted funding levels. Second, during our review of documentation for BOP's fiscal year 2008 cost estimate, in some cases we required the guidance of BOP budget analysts to identify backup support because the documentation was insufficient to allow someone unfamiliar with the budget to locate detailed corroborating data. By documenting all steps, BOP would be better positioned to recreate its budget cost estimates in the event of attrition among those who initially developed them. According to BOP, from fiscal years 2004 through 2008, costs for non-salary inmate medical care and utilities exceeded funding levels in the President's budget request by about $131 million and $55 million, respectively. As a result, BOP has faced funding gaps in its operations account that has left it with limited flexibility to manage its continually growing inmate population.

Why GAO Did This Study:
The Department of Justice‘s (DOJ) Federal Bureau of Prisons (BOP) is
responsible for the custody and care of about 209,000 federal inmates”a
population which has grown by 44 percent over the last decade. In
fiscal years 2008 and 2009, the President requested additional funding
for BOP because costs for key operations were at risk of exceeding
appropriated funding levels. GAO was congressionally directed to
examine (1) how BOP estimates costs when developing its annual budget
request to DOJ; (2) the extent to which BOP‘s methods for estimating
costs follow established best practices; and (3) the extent to which
BOP‘s costs for key operations exceeded requested funding levels
identified in the President‘s budget in recent years, and how this has
affected BOP‘s ability to manage its growing inmate population. In
conducting our work, GAO analyzed BOP budget documents, interviewed BOP
and DOJ officials, and compared BOP‘s cost estimation documentation to
criteria in GAO‘s Cost Estimating and Assessment Guide.
What GAO Found:
BOP uses three general steps to estimate costs for its annual budget
submission: (1) estimating cost increases to maintain service levels,
such as inmate medical care and utilities; (2) projecting inmate
population changes for the budget year and for several years into the
future using a modeling program that incorporates data on the current
inmate population and estimated incoming population and associated
sentences; and (3) estimating costs to both provide additional capacity
to house projected inmate population growth and implement new programs,
such as activating new prisons.
BOP‘s methods for cost estimation largely reflect best practices
outlined in GAO‘s Cost Estimating and Assessment Guide. BOP followed a
well-defined process for developing a mostly comprehensive, well
documented, accurate, and credible cost estimate for fiscal year 2008.
For example, BOP used relevant historical cost data and considered
adjustments for general inflation when estimating costs for its budget
request to DOJ. Moreover, BOP‘s methods for projecting inmate
population changes were accurate, on average, to within 1 percent of
the actual inmate population growth from fiscal year 1999 to August
2009. Still, BOP could strengthen its methods in two ways. First, BOP
has not quantified the level of confidence associated with its cost
estimate. While not required by the Office of Management and Budget or
DOJ, conducting an uncertainty analysis of this kind is a best
practice. By providing the results of such analysis to DOJ, BOP
officials could share advance information on the probability and
associated risks of operating expenses exceeding enacted funding
levels. Second, during our review of documentation for BOP‘s fiscal
year 2008 cost estimate, in some cases we required the guidance of BOP
budget analysts to identify backup support because the documentation
was insufficient to allow someone unfamiliar with the budget to locate
detailed corroborating data. By documenting all steps, BOP would be
better positioned to recreate its budget cost estimates in the event of
attrition among those who initially developed them.
According to BOP, from fiscal years 2004 through 2008, costs for non-
salary inmate medical care and utilities exceeded funding levels in the
President‘s budget request by about $131 million and $55 million,
respectively. As a result, BOP has faced funding gaps in its operations
account that has left it with limited flexibility to manage its
continually growing inmate population.

What GAO Recommends:
GAO recommends that BOP (1) conduct an uncertainty analysis quantifying
the extent to which its operational costs could vary due to changes in
key cost assumptions and submit the results, along with budget
documentation, to DOJ; and (2) improve documentation of calculations
used to estimate its costs. BOP agreed with GAO‘s recommendations.

The Department of Justice's (DOJ) Federal Bureau of Prisons' (BOP)
mission is to protect society by confining offenders in the controlled
environments of prisons and community-based facilities that are safe,
humane, cost-efficient, and appropriately secure. As of October 1,
2009, BOP was responsible for overseeing a total federal inmate
population of approximately 209,000--a population which has grown by 44
percent since fiscal year 2000.[Footnote 1] In recent years, BOP has
faced challenges in meeting its operational workload responsibilities
to manage this growth. In fiscal year 2008, DOJ reported to the Office
of Management and Budget (OMB) that BOP would be unable to operate at
the funding levels in its appropriation because costs for key
operations were at risk of exceeding appropriated funding levels. BOP
reported that it again anticipated a funding gap in fiscal year 2009,
and in response, Congress provided appropriations above the amount
requested in the President's budget.
This report responds to congressional direction in the explanatory
statement accompanying the Omnibus Appropriations Act, 2009.[Footnote
2] In accordance with this explanatory statement, and in consultation
with the House and Senate Appropriations Committee staff, we are
reporting on BOP's methods for cost estimation, including the pricing
of utilities and inmate medical care costs. Specifically, we address
issues pertaining to (1) how BOP estimates costs when developing its
annual budget request to DOJ; (2) the extent to which BOP's methods for
estimating costs follow established best practices or guidelines; and
(3) the extent to which BOP's costs for key operations exceeded
requested funding levels identified in the President's budget in recent
years, and how this has affected BOP's ability to manage its growing
inmate population. On September 10, 2009, we provided a briefing to
staff of the House and Senate Appropriations Subcommittees on Commerce,
Justice, Science, and Related Agencies. Prior to this briefing, we
provided a draft of the briefing to responsible DOJ and BOP officials,
who generally agreed with our findings. This report (1) provides a
summary of our briefing and (2) transmits recommendations that we are
making to the Attorney General of the United States. The full briefing,
including our scope and methodology, is reprinted as appendix I.
Written comments from DOJ are reprinted as appendix II.
To address these objectives, we analyzed BOP documentation to obtain
information on the guidelines and processes BOP used to estimate costs
in its annual budget submission, including annual DOJ and BOP budget
development guidelines and memorandum and OMB's Circular A-11[Footnote
3]. We also analyzed available documentation, such as the formulas BOP
used to compute its fiscal year 2008 budget cost estimate, and compared
the documentation BOP used to develop its fiscal year 2008 budget cost
estimate to criteria for cost estimating best practices identified in
GAO's Cost Estimating and Assessment Guide: Best Practices for
Developing and Managing Capital Program Cost[Footnote 4]s.
Additionally, we reviewed BOP documentation of operations costs for
inmate medical care and utilities and compared these costs to the
amount of funding requested in the President's annual budget submission
to Congress for BOP (known as the President's budget). Finally, we
interviewed cognizant BOP and DOJ budget development officials to
obtain information about BOP's budget cost estimating methods and the
factors contributing to BOP's operational costs exceeding funding
levels, and how this has affected BOP's ability to manage its growing
inmate population. Through document reviews and interviews with agency
officials knowledgeable about controls in place to maintain the
integrity of BOP cost and inmate population data that BOP reported
using to estimate costs for its annual budget submission to DOJ, we
determined that the data were sufficiently reliable for the purposes of
this report.
We conducted this performance audit from May 2009 to November 2009 in
accordance with generally accepted government auditing standards. Those
standards require that we plan and perform the work to obtain
sufficient, appropriate evidence to provide a reasonable basis for our
findings and conclusions based on our objectives. We believe that the
evidence obtained provides a reasonable basis for our findings and
conclusions based on our objectives.
BOP Estimates Costs for Its Annual Budget Using Three General Steps:
When developing its annual budget submission, BOP uses three general
steps to estimate costs for its two budget accounts--the Salaries and
Expenses account (known as its operational budget) and its Buildings
and Facilities account.[Footnote 5] First, BOP estimates cost increases
for maintaining the current level of services for operations as
provided in the prior year's enacted budget.[Footnote 6] These include
costs to address mandatory staff pay raises and benefit increases,
inmate medical care, and utilities. BOP primarily analyzes historical
obligations from the past five years to identify average annual
operating cost increases. BOP also considers economic indicator
information to estimate general inflationary cost increases, using data
from the Bureau of Labor Statistics Consumer Price Index, among other
sources.
Second, BOP projects inmate population changes for the budget year and
for several years into the future. BOP uses a modeling program that
identifies each inmate as a unique record tied to variables such as
conviction year, sentence term, and conviction type, with data obtained
from a variety of sources, including the Administrative Office of the
U.S. Courts, the U.S. Sentencing Commission, and the Executive Office
for U.S. Attorneys. The model identifies the number of inmates
currently in BOP's system and the length of those inmates' sentences,
as well as the number of inmates estimated to enter the BOP system and
the length of their sentences. For example, for the fiscal year 2010
annual budget submission, BOP projected a net growth in its inmate
population of 4,500 inmates.
Third, BOP estimates costs to both house the projected number of new
inmates, including building and facility requirements, and fund any new
initiatives. According to BOP, a rising inmate population is the
primary driver of new service costs (see figure 1 for graph showing
federal inmate population growth from fiscal years 2000 through 2009).
Thus, for any budget year, BOP uses inmate population projections to
determine the necessary bedspace to house additional inmates. BOP
estimates these associated incarceration costs by (1) determining how
to distribute the incoming prisoners across newly activated facilities,
existing facilities, or contract facilities; and (2) calculating
staffing and other operational costs to manage the additional inmates
at its facilities. BOP also identifies and estimates costs for new
initiatives, such as the activation of a new BOP facility, by reviewing
the proposals submitted by its divisions and regional offices, as well
as historical data on costs for implementing such initiatives.

For its Buildings and Facilities account, BOP identifies new program
costs associated with new construction and maintenance and repair of
existing facilities. Using its long-term inmate population projections,
BOP considers new construction proposals based on need, funding, and
the anticipated speed of construction. BOP estimates construction costs
largely by using analogous building costs for similar security level
facilities, as well as considering assumptions, such as the rate of
inflation and when potential construction would begin. BOP ranks
maintenance and repair proposals by assigning safety the highest
priority and estimates costs based on information it obtains from a
construction cost estimation company.
BOP's Methods for Estimating Costs Largely Reflect Best Practices:
BOP's methods for estimating costs in its annual budget requests to DOJ
largely reflect the best practices outlined in GAO's Cost Estimating
and Assessment Guide. Specifically, BOP followed a well-defined process
for developing a mostly comprehensive, well documented, accurate, and
credible cost estimate for fiscal year 2008.[Footnote 7] For example,
BOP used relevant historical cost data and considered adjustments for
general inflation when estimating costs for its budget request to DOJ.
Moreover, BOP's methods for projecting inmate population changes have
been largely accurate. For example, we found BOP's projections were
accurate, on average, to within 1 percent of the actual inmate
population growth from fiscal year 1999 through August 20, 2009.
We identified two areas where BOP could strengthen its methods for
estimating costs in its annual budget submission. First, according to
best practices described in GAO's Cost Estimating and Assessment Guide,
it is better for decision makers to know the range of potential costs
that surround an estimate and the reasons behind what drives that range
rather than just having a point estimate from which to make their
decision. An uncertainty analysis provides a range of costs that span a
best and worst case spread. While not required by OMB or DOJ in annual
budget development guidance, conducting an uncertainty analysis of this
kind is a best practice. BOP has not conducted an uncertainty analysis,
and therefore has not quantified the level of confidence associated
with its cost estimate. By providing the results of such analysis to
DOJ, BOP officials could share advance information on the probability
and associated risks of operating expenses exceeding enacted funding
levels--a situation BOP faced in fiscal year 2008.
Second, during our review of documentation for BOP's fiscal year 2008
cost estimate, we sometimes required the guidance of BOP budget
analysts to identify backup support. This was because the documentation
BOP provided was insufficient to allow someone unfamiliar with the
budget to locate detailed corroborating data. For example, in reviewing
BOP's fiscal year 2008 cost estimate for a health service initiative
related to expanding kidney dialysis treatment for inmates, we required
a budget official's assistance in locating supporting formulas used to
calculate the estimate. Best practices for cost estimation include
providing enough detail so that the documentation serves as an audit
trail that allows for clear tracking of cost estimates over time. By
documenting all steps for developing its budget cost estimate, BOP
would be better positioned to recreate its estimates in the event of
attrition within its budget office among those who developed initial
budget cost estimates.
In providing feedback on our initial findings, BOP budget officials
indicated that taking these steps would strengthen their methods for
estimating costs in their annual budget submission to DOJ.
Costs for Key Operations Have Exceeded the Funding Levels Requested in
the President's Budget in Recent Years:
BOP's costs for key operations to maintain basic services, such as
those for inmate medical care and utilities, exceeded the funding
levels requested in the President's budget from fiscal years 2004
through 2008, limiting BOP's ability to manage its growing inmate
population. During this period, BOP's annual non-salary inmate medical
care and utilities costs exceeded funding levels in the President's
budget request by a total of about $131 million and $55 million,
respectively, largely due to inflation and inmate population growth.
[Footnote 8]
* According to BOP, from fiscal years 2004 through 2008, BOP's annual
non-salary inmate medical care costs increased by a total of about
$146.5 million. In contrast, during this period, the President's budget
requested funding increases for non-salary inmate medical care totaling
approximately $15.4 million.
* According to BOP, from fiscal years 2004 through 2008, BOP's annual
utilities costs increased by a total of $87 million. In contrast,
during this period, the President's budget requested funding increases
for utilities totaling approximately $31.6 million.
Table 1 compares BOP's rates of annual cost growth due to inflation and
inmate population growth with the President's budget requests for
funding for non-salary inmate medical care and utilities from fiscal
years 2004 through 2008.

Inflation and Inmate Population Growth and Average Annual Funding in
President's Budget Request for BOP, Fiscal Years 2004 through 2008:
Inmate medical care (non-salary):
Average annual rate of cost growth incurred by BOP, fiscal years 2004

through 2008: 9.8%;
Average annual rate of funding growth in President's budget request,
fiscal years 2004 through 2008: 3.2%.

[End of table]
When BOP has not received funding to cover the operational cost
increases it has incurred, in some years it has used Salaries and
Expenses funding planned for other areas to cover these costs. For
example, one of BOP's highest priorities is to increase staffing levels
of corrections officers. However, BOP officials reported using Salaries
and Expenses account funds initially planned for hiring additional
corrections officers in fiscal years 2008 and 2009 to instead cover
base operations cost increases related to inmate medical care,
utilities, and personnel salary and benefit adjustments that were
unfunded in the President's budget requests.
As with any other DOJ component, BOP's budget requests are governed by
DOJ and OMB budget development guidance. For example, DOJ budget
development guidance for fiscal years 2008 and 2009 required components
to limit cost growth for current services to no more than 4 percent
greater than prior year levels. DOJ reported that this guidance was a
general instruction given to all components, but recognized that BOP is
different because its costs are less discretionary since BOP does not
control the number of inmates for which it must care. In this way, DOJ
reported that it did not automatically reject budget submissions from
BOP that exceeded the cap, but instead required BOP to submit
substantive information to justify need.
DOJ also reported that OMB does not automatically provide funds for
inflationary cost increases. DOJ cited OMB policy stating that
inflationary adjustments for discretionary costs (such as utilities)
can include some, all, or no allowance for inflation. DOJ officials
reported that OMB typically does not include general inflationary
adjustments that DOJ submits on behalf of BOP.
Nonetheless, DOJ has reported to OMB that other DOJ components could
reduce operations, implement across-the-board hiring freezes, and
implement policy changes that would reduce costs if faced with funding
shortfalls similar to what BOP has faced in its operations budget.
However, DOJ reported that BOP has already implemented significant
reductions to programs and streamlined and centralized administrative
functions to eliminate 2,300 positions. DOJ also reported that BOP has
limited flexibility because almost all of BOP's operational costs are
devoted to staff salaries and provision of services. According to BOP
data, in fiscal years 2007 and 2008, 99.5 percent of BOP's Salaries and
Expenses budget was fixed for its operations for paying staff salaries
and providing services to house and care for the inmate population.
Conclusions:
In each of the last 2 fiscal years, BOP has needed additional funding
to meet its operating costs for managing its growing inmate population.
However, we found that BOP's cost estimation methods largely reflect
GAO's cost estimating best practices. Furthermore, BOP officials
reported, and DOJ officials acknowledged, that BOP has already
implemented significant reductions in operations costs, such as by
eliminating positions and centralizing administrative functions. Given
BOP's unique responsibility for managing this population, and its
limited discretion when costs for key operations exceed funding levels,
it is especially important for BOP to develop accurate cost estimates
and clearly convey to decision makers the potential risk of costs
exceeding funding levels.
In light of these circumstances, BOP's budget cost estimation practices
could be strengthened in two ways. First, although BOP is not required
to report in its annual budget submission the extent to which actual
costs may be expected to vary from cost estimates, we have identified
the provision of an uncertainty analysis as a best practice. If BOP
identified its level of cost estimation confidence and provided this
information to DOJ, DOJ could more fully understand the range of
potential costs--and the potential need for more funding--if estimating
assumptions for key cost drivers, such as inmate population growth, do
not hold true.
Second, by improving documentation of all steps for developing its cost
estimate, BOP would be better positioned to re-create its estimates in
the event of attrition within its budget office among those who
developed initial cost estimates.
Recommendations for Executive Action:
To improve transparency in BOP's cost estimation process, as well as
DOJ's annual budget formulation and justification process, and to
provide DOJ with more detailed information to consider when
deliberating its budget proposal for BOP, we recommend that the
Attorney General take the following two actions:
* instruct the BOP Director to require the BOP budget staff to conduct
an uncertainty analysis quantifying the extent to which operations
costs could vary due to changes in key cost assumptions and submit the
results along with budget documentation to DOJ so that DOJ could be
aware of the range of likely costs and BOP's associated confidence
levels; and:
* instruct the BOP Director to require the BOP budget staff to improve
documentation of calculations used to estimate its costs.
Agency Comments:
We provided a draft of this report to DOJ for its review and comment.
The BOP Director provided written comments on this draft and concurred
with our findings and recommendations. BOP stated that including the
results of an uncertainty analysis in the budget document would provide
DOJ, OMB, and Congress better context for decision making and stated
that it would include such analysis in preparation of its 2012 budget
submission. BOP also stated that if time permits, it would work with
DOJ and OMB to incorporate an uncertainty analysis into the President's
2011 budget. BOP's comments are reproduced in appendix II.
We are sending copies of this report to the Attorney General and
interested congressional committees. In addition, this report will be

Introduction:
In recent years, the Department of Justice‘s (DOJ) Federal Bureau of
Prisons (BOP) has faced challenges in meeting its operational workload
responsibilities for overseeing the federal inmate population. In
fiscal year 2008, DOJ reported to the Office of Management and Budget
(OMB) that BOP would be unable to operate at the funding levels in its
appropriation because costs for key operations were at risk of
exceeding appropriated funding levels. BOP reported that it again
anticipated a funding gap in fiscal year 2009, and in response Congress
provided appropriations above the amount in the President‘s budget
request.
* Fiscal year 2008: BOP received a total of $296.3 million in funding
after its initial appropriation was enacted, including $109.2 million
transferred from other DOJ accounts, $178 million from the Supplemental
Appropriations Act, 2008 and $9.1 million relating to the Global War on
Terrorism in the Supplemental Appropriations Act, 2008.[Footnote 9]
* Fiscal year 2009: BOP received a total of $160 million in funding
above the President‘s request through the Omnibus Appropriations Act,
2009[Footnote 10] and $5 million through the Supplemental
Appropriations Act, 2009.[Footnote 11]
Objectives, Scope, and Methodology:
Objectives:
The explanatory statement accompanying the Omnibus Appropriations Act,
2009 directed GAO to review BOP‘s methods for determining resource
requirements.[Footnote 12] We designed our reporting objectives to
answer the following three questions:
1. How does BOP estimate costs when developing its annual budget
request to DOJ?
2. To what extent do BOP‘s methods for estimating costs follow
established best practices or guidelines?
3. To what extent have BOP‘s costs for key operations exceeded
requested funding levels identified in the President‘s budget in the
last five fiscal years, and how has this affected BOP‘s ability to
manage its growing inmate population?
Scope and Methodology: Objective 1:
To determine how BOP estimates costs when developing its annual budget
request to DOJ, we:
* analyzed BOP documentation, including budget development guidelines,
planning documents, and memorandum to obtain information on the steps
BOP uses to estimate costs and the information BOP considers when doing
so;
* reviewed OMB and DOJ budget development guidance, including OMB‘s
Circular A-11 and DOJ annual budget development guidelines, to obtain
information on federal budget formulation standards and requirements
BOP must follow in preparing its annual budget request to DOJ,[Footnote
13] and;
* interviewed cognizant program officials from BOP‘s Administration
Division, including senior officials from BOP‘s Budget Development
Office and Capacity Planning Branch, to learn about BOPs methods for
estimating costs. We also interviewed cognizant program officials from
BOP‘s Office of Research and Evaluation to obtain information on BOP‘s
methods for estimating inmate population increases.
Scope and Methodology: Objective 2:
To determine the extent to which BOP‘s methods for estimating costs
follow established best practices or guidelines, we:
* analyzed available documentation, including BOP's fiscal year 2008
budget cost estimate and other relevant agency documentation, such as
the formulas BOP used to compute its fiscal year 2008 budget cost
estimate;
* interviewed cognizant program officials from BOP‘s Administration
Division, including the Budget Development Chief, to understand how BOP
developed its budget cost estimates and to identify supporting budget
development documentation; and;
* compared the documentation BOP used to develop its fiscal year 2008
budget cost estimate with criteria for cost estimating best practices
identified in GAO‘s Cost Estimating and Assessment Guide: Best
Practices for Developing and Managing Capital Program Costs.[Footnote
14]
Scope and Methodology: Objective 3:
To determine the extent to which BOP‘s costs for key operations
exceeded funding levels requested in the President‘s budget over the
past five fiscal years and how this has affected BOP‘s ability to
manage its growing inmate population, we:
* reviewed BOP documentation, including reported obligations costs for
maintaining key operations, and compared these costs to requests for
funding in the President‘s annual budget submission to Congress for
BOP;
* interviewed BOP budget development officials, as well as budget
development officials from the DOJ Justice Management Division, to
obtain information on the factors officials reported contributing to
BOP‘s operational costs exceeding funding levels.
Scope and Methodology:
To assess the reliability of the information we obtained about BOP's
methods for estimating costs for its annual budget submission, we
compared the documents BOP provided supporting its budget estimates for
fiscal years 2004 to 2008 with information contained in the President's
budget request for BOP for those years to determine the consistency of
the information.
We also interviewed agency officials knowledgeable about controls in
place to maintain the integrity of (1) inmate population and sentenced
offender data BOP used to populate its inmate population projection
model for fiscal years 1999 to 2009 and (2) data on annual operations
costs BOP reported between 2004 and 2008, including inmate medical care
and utilities. As a result, we determined that the data were
sufficiently reliable for the purposes of this report.
We conducted this performance audit from May 2009 to September 2009 in
accordance with generally accepted government auditing standards. Those
standards require that we plan and perform the work to obtain
sufficient, appropriate evidence to provide a reasonable basis for our
findings and conclusions based on our objectives. We believe that the
evidence obtained provides a reasonable basis for our findings and
conclusions based on our objectives.
Results in Brief:
BOP develops its annual budget request to DOJ using three general
steps: (1) estimating cost increases needed to maintain current service
levels; (2) projecting inmate population changes; and (3) estimating
costs to provide additional capacity to house inmate population growth
and implement new programs.
BOP‘s methods for cost estimation largely reflect best practices
outlined in GAO‘s Cost Estimating and Assessment Guide. BOP followed a
well defined process for developing a mostly comprehensive, well-
documented, accurate, and credible cost estimate for fiscal year 2008;
however, BOP has not quantified the level of confidence associated with
its cost estimate. While not required by OMB or DOJ, conducting
uncertainty analyses of this kind is a best practice. By providing the
results of such analyses to DOJ, BOP officials could share advance
information on the probability and associated risks of operating
expenses exceeding enacted funding levels”a situation BOP faced in
fiscal year 2008.
BOP‘s costs for key operations to maintain basic services, such as
those for inmate medical care and utilities, have exceeded the funding
levels requested in the President‘s budget over the last 5 fiscal
years, and this has limited BOP‘s ability to manage its growing inmate
population. According to BOP, between fiscal years 2004 and 2008, costs
for non-salary inmate medical care and utilities exceeded funding
levels in the President‘s budget request by about $131 million and $55
million, respectively.
To improve transparency in BOP‘s cost estimation process, as well as
DOJ‘s annual budget formulation and justification process, we plan to
make two recommendations to the Attorney General:
1. instruct the BOP Director to require BOP budget staff to conduct an
uncertainty analysis quantifying the extent to which operational costs
could vary due to changes in key cost assumptions”and submit the
results, along with budget documentation, to DOJ so that DOJ can be
aware of the range of possible costs and BOP's confidence levels
associated with each point along the range;
2. instruct the BOP Director to require the budget staff to improve
documentation of calculations used to estimate its costs.
DOJ and BOP generally agreed with our findings and provided technical
comments, which we integrated into our findings as appropriate.
Background–BOP‘s Mission:
BOP‘s mission is to protect society by confining offenders in the
controlled environments of prisons and community-based facilities that
are safe, humane, cost-efficient, and appropriately secure.
* As of October 1, 2009, BOP was responsible for overseeing a total
federal inmate population of approximately 209,000.
* Approximately 172,500 federal inmates”83 percent”were housed in 115
BOP-operated facilities throughout the country. The remaining inmates
were housed primarily in contract confinement (private facilities and
halfway houses, operated by contractors or state/local governments).
Background–Federal Budget Formulation Process:
Through the multi-phase federal budget formulation process, BOP is
required to identify resource requirements and estimate costs for its
annual budget request to DOJ. This process is guided by OMB, which
makes decisions on executive agencies‘ budgets and submits them as the
’President‘s Request“to Congress. Key steps in this process involve:
* OMB issuing Circular A-11 to federal agencies, providing detailed
instructions for submitting budget data and materials, as well as
criteria for developing budget submissions;
* DOJ issuing to all components its annual budget development
guidelines;
* BOP submitting its budget request to DOJ‘s Justice Management
Division about a year and a half prior to the budget year in question;
*The Attorney General analyzing all DOJ components‘ budget requests in
light of department-wide priorities and compiling and submitting the
DOJ annual budget submission to OMB; and;
* OMB making final decisions on all agencies‘ budgets and submitting
the President‘s Request to Congress, which aggregates submissions for
all of DOJ‘s components, including BOP.
Figure 1 provides a high-level overview of this process.

Background–BOP‘s Budget Composition:
BOP‘s appropriated budget is comprised of the Salaries and Expenses
(S&E) and Buildings and Facilities (B&F) accounts.
* The S&E account”known as BOP‘s operations budget”includes sub-
accounts covering costs for staffing; medical care; food; and
utilities, such as water and gas. In fiscal year 2009, staffing costs
for employee salaries comprised about 60 percent of this account.
* The B&F account has sub-accounts covering costs for design and
construction of new facilities and modernization and repair (M&R) of
existing facilities.
* S&E expenses have accounted for the vast majority of BOP‘s annual
enacted budget from fiscal years 1999 through 2008”averaging about 90
percent.
The President‘s fiscal year 2010 budget request for BOP‘s S&E and B&F
accounts totals $6.1 billion, which is 23 percent of DOJ‘s $26.7
billion budget.
Figure 2 compares the President‘s request for BOP to its enacted
funding levels from fiscal year 1999 through 2009, and figure 3 shows
the composition of the President‘s request (S&E versus B&F) for BOP
over the same period.

Background–BOP‘s Challenges:
* From fiscal years 2000 through 2009, BOP‘s total inmate population
level increased by 44 percent”from 145,125 to 209,027. BOP estimates
that the total inmate population will continue to rise by about 4,500
inmates per year over the next decade.
* During this period, BOP reports that crowding levels (the percentage
of inmates housed in facilities above the rated capacity for safe and
secure incarceration) have grown.[Footnote 15] BOP currently reports a
system-wide crowding rate of 37 percent”more than double the rate (15
percent) that BOP has determined to be its long-term target for
reducing overcrowding.
* According to BOP, as inmate population and crowding have increased,
BOP‘s overall inmate to staff ratio increased by nearly 18 percent from
fiscal year 2000 to 2008, from 4.13 to 1 to 4.86 to 1. BOP reports that
this has caused a significant reduction in its ability to effectively
supervise inmates in its facilities.
* A 2005 BOP study found that an increase in crowding levels or inmate
to staff ratios leads to an increase in serious violence among
inmates.[Footnote 16]
* As of August 1, 2009, BOP reported being staffed at 34,829”about 88
percent of its authorized Full Time Equivalent (FTE) staffing level of
39,692. About half of its authorized positions are for corrections
officers.
* Figure 4 compares BOP S&E staffing levels to its inmate population
beginning in fiscal year 2000.

Objective 1–How does BOP estimate costs when developing its annual
budget submission?
BOP estimates costs using three general steps:
Step 1: BOP estimates the costs necessary to maintain operations for
existing workload requirements (current services) by using the prior
year‘s request or enacted budget as a baseline.[Footnote 17]
Step 2: BOP projects inmate population changes for the budget year.
Step 3: BOP estimates costs to accommodate projected inmate population
growth, including the provision of new programs, such as activation of
a new BOP prison facility, for the budget year.
Objective 1–Estimating Costs to Maintain Current Services (S&E
Account):
First, BOP estimates cost increases for maintaining the level of
services”operational costs”provided in the prior year‘s enacted budget
for the S&E account.
* These costs include adjustments to address mandatory staff pay raises
and benefit increases, inmate medical care, and utilities across BOP‘s
115 facilities.
BOP primarily analyzes historical obligations from the last 5 years to
identify average annual operating cost increases.
BOP also considers economic indicator information to estimate general
inflationary cost increases, using data from the Bureau of Labor
Statistics Consumer Price Index and other sources.
Objective 1–Projecting Population Changes:
Second, BOP projects inmate population changes for the budget year, and
for 9 years into the future.
* BOP uses a modeling program that identifies each inmate as a unique
record tied to variables such as conviction year, sentence term, and
conviction type.
* BOP‘s model uses data and information from a variety of sources,
including the Administrative Office of the U.S. Courts, the U.S.
Sentencing Commission, and the Executive Office for U.S. Attorneys to
identify:
- Number of inmates currently in prison and the length of their
sentences, and;
- Number of inmates estimated to enter prison and the length of their
sentences.
* For the fiscal year 2010 annual budget submission, BOP projected a
net growth of 4,500 inmates.
Objective 1–Estimating Costs to Provide Additional Capacity:
Third, BOP estimates costs to both house the projected number of new
inmates, including building and facility requirements, and fund any new
initiatives.
* According to BOP, a rising inmate population is the primary driver of
new service costs.
- For the budget year, BOP uses inmate projections to determine
necessary bedspace to house additional inmates.
- For future years, BOP uses inmate projections to plan for long term
capacity needs, including new construction and arrangements for
contract confinement.
* BOP estimates the associated incarceration costs by (1) determining
how to distribute incoming prisoners across newly activated facilities,
existing facilities, or privately operated facilities, and (2)
calculating staff and other operational costs at each facility type.
* BOP identifies and estimates costs for new initiatives/program
increases, such as activation of a new BOP prison facility, by
reviewing the proposals submitted by its divisions and regional
offices, and historical data.
Objective 1–Estimating Costs to Provide Additional Capacity (B&F
Account)BOP also identifies new program costs associated with its B&F
account, including new construction and M&R.
* Using its long term population projections, BOP considers new
construction proposals based on need, funding, and the anticipated
speed of construction.
- BOP estimates construction costs (for new prisons or expansions to
existing facilities) largely by using analogous building costs for
similar security level facilities. Cost estimates are also based on
assumptions, including the rate of inflation and when construction will
begin.
- M&R project proposals are ranked by assigning safety the highest
priority, with lesser importance given to improving accessibility and
updating facilities more than 50 years old. BOP estimates costs for
replacement values through information it obtains from a construction
cost estimation company.
- Since fiscal year 2005, OMB has placed a moratorium on new BOP prison
construction because OMB has focused on contracting with private
prisons to address bedspace needs. However, BOP has identified new
construction plans and included proposals for new construction as part
of its capacity plan.[Footnote 18]
Objective 2–To what extent do BOP‘s methods for estimating costs follow
established best practices or guidelines?
BOP‘s methods for estimating costs in its annual budget requests to DOJ
largely reflect the four best practices outlined in GAO‘s Cost
Estimating and Assessment Guide.
* GAO‘s Cost Estimating and Assessment Guide has identified 12
practices that are the basis for effective cost estimation.[Footnote
19] We associate these practices with four characteristics: accurate,
well documented, credible, and comprehensive. OMB endorsed this
guidance as being sufficient for meeting most cost estimating
requirements, including for budget formulation.
* If followed correctly, these practices should result in reliable and
valid cost estimates that (a) can be easily and clearly traced,
replicated,and updated; and (b) enable managers to make informed
decisions.
Objective 2–Extent To Which BOP‘s Cost Estimation Methods Reflect GAO‘s
Cost Estimation Best Practices:
As table 1 illustrates, we found that BOP‘s methods for estimating
costs met one and substantially met three of these four practices. The
following explains the definitions we used in assessing BOP‘s methods
for estimating costs in its annual budget submission to DOJ:
Met–BOP provided complete evidence that satisfies the entire criterion;
Substantially Met–BOP provided evidence that satisfies a large portion
of the criterion;
Partially Met–BOP provided evidence that satisfies about half of the
criterion;
Minimally Met–BOP provided evidence that satisfies a small portion of
the criterion;
Not Met–BOP provided no evidence that satisfies any of the criterion.
DOJ officials reported being satisfied with BOP‘s cost estimation
methods, noting that they could not identify any area needing
improvement.
Objective 2–BOP‘s Methods for Estimating Costs in its Annual Budget
Requests to DOJ Largely Reflect GAO Best Practices:
Table 1: Extent to Which BOP‘s Cost Estimating Methods Reflect GAO Best
Practices:
Best practice: Accurate;
Explanation: The cost estimates should provide for results that are
unbiased and should not be overly conservative or optimistic. In
addition, the estimates should be updated regularly to reflect material
changes in the program, and steps should be taken to minimize
mathematical mistakes and their significance. Among other things, the
estimate should be grounded in a historical record of cost estimating
and actual experiences on comparable programs.
Satisfied? Met.
Best practice: Well documented;
Explanation: The cost estimates should have clearly defined purposes
and be supported by documented descriptions of key program or system
characteristics. Additionally, they should capture in writing such
things as the source data used and their significance, the calculations
performed and their results, and the rationale for choosing a
particular estimating method. Moreover, this information should be
captured in such a way that the data used to derive the estimate can be
traced back to, and verified against, their sources. The final cost
estimate should be reviewed and accepted by management.
Satisfied? Substantially met.
Best practice: Credible;
Explanation: The cost estimates should discuss any limitations in the
analysis performed due to uncertainty surrounding data or assumptions.
Further, the estimates‘ derivation should provide for varying any major
assumptions and recalculating outcomes based on sensitivity analyses,
and their associated risks/uncertainty should be disclosed. Also, the
estimates should be verified based on cross-checks using other
estimating methods and by comparing the results with independent cost
estimates.
Satisfied? Substantially met.
Best practice: Comprehensive;
Explanation: The cost estimates should include both government and
contractor costs over the program‘s full life cycle, from the inception
of the program through design, development, deployment, and operation
and maintenance to retirement. They should also provide an appropriate
level of detail to ensure that cost elements are neither omitted nor
double counted and include documentation of all cost-influencing ground
rules and assumptions.
Satisfied? Substantially met.
Source: GAO analysis.
[End of table]
Objective 2–BOP‘s Cost Estimating Methods Met Characteristics for
Accuracy:
Consistent with best practices, BOP used relevant historical cost data
and considered adjustments for general inflation when estimating costs
for its fiscal year 2008 budget request to DOJ, and its methods for
projecting inmate population have been largely accurate.
* BOP officials reported estimating costs for medical care and
utilities for the budget year in question based on historical
obligations over the prior three to five years. For example, BOP
provided documentation that officials reported using to develop BOP‘s
fiscal year 2009 inmate medical care cost estimate showing BOP‘s annual
non-salary inmate medical care costs had increased an average of about
10 percent annually between fiscal years 2003 and 2005.[Footnote 20]
* BOP‘s total inmate population projections were accurate, on average,
to within 1 percent of the actual inmate growth from fiscal year 1999
to August 20, 2009.
- BOP overestimated the inmate population for 8 of the 11 fiscal years
reviewed.
* Figure 5 compares BOP‘s projected population levels as reflected in
the President‘s request compared to the actual inmate populations at
the end of each fiscal year, 1999 to 2009 (projected).
* Table 2 presents the difference between the projected and actual
population increases.

Objective 2–BOP‘s Cost Estimating Methods Substantially Met
Characteristics for Being Well Documented:
Consistent with best practices, BOP clearly defined the purpose of its
cost estimates,and its calculations and results substantially met
characteristics for being well documented.
* We reviewed BOP‘s fiscal year 2008 budget request to DOJ and
supporting documentation and found budget officials had documented the
formulas they used to calculate cost elements for new initiatives, such
as activation-related costs for a new prison facility planned to open
in the budget year.
* In some cases, however, we required the guidance of BOP budget
analysts to identify backup support because the documentation was
insufficient to allow someone unfamiliar with the budget to locate
detailed corroborating data. For example, in reviewing BOP‘s fiscal
year 2008 cost estimate for a health service initiative related to
expanding kidney dialysis, we required a budget official‘s assistance
in locating supporting formulas used to calculate the estimate. Best
practices include providing enough detail so that the documentation
serves as an audit trail to allow for clear tracking of cost estimates
over time.
* Documenting all steps for developing its cost estimate would better
position BOP to recreate its estimates in the event of attrition within
its budget office among those who have developed initial cost
estimates.
Objective 2–BOP‘s Cost Estimating Methods Substantially Met
Characteristics for Credibility:
Consistent with best practices, BOP performed independent government
cost estimates related to constructing new prisons and used historical
data to estimate key operational costs, including utilities and inmate
medical care, and its calculations and results substantially met
characteristics for credibility.
* BOP performed cross-checks by benchmarking new estimates against
historical data, such as by estimating medical care costs based on cost
obligations in recent years and developed numerous risk analyses and
impact scenarios of funding cuts.
* Although not required to do so by OMB or DOJ annual budget
development guidelines, BOP did not perform an uncertainty analysis
consistent with best practices to quantify the risk associated with
changes to various assumptions that drive its cost estimates.[Footnote
21] Major assumptions include the inmate population projection;
inflation indices for medical care and utilities; and annual salary
increases.
* Such an analysis would help provide DOJ, Congress, and other
stakeholders with information to determine the probability that costs
for key operations, such as inmate medical care and utilities, may
exceed funding levels requested in the President‘s budget.
Objective 2–BOP‘s Cost Estimating Methods Substantially Met
Characteristics for Being Comprehensive:
Consistent with best practices, BOP detailed pertinent costs related to
its S&E and B&F accounts across sub-accounts. This level of detail
helped ensure that no cost elements were omitted or double counted in
its budget request submission to DOJ, and that BOP‘s calculations and
results substantially met characteristics for comprehensiveness.
* BOP relied on ground rules and assumptions, such as using inmate
population projections to drive cost estimates for capacity needs and
using historical obligation trends to estimate growth for utilities and
inmate medical care costs.
* However, as noted earlier, BOP did not determine risk distributions
for all assumptions, which would enable it to perform an uncertainty
analysis for key cost elements.
Objective 3–To what extent have BOP‘s costs for key operations exceeded
requested funding levels in the President‘s budget in the last five
fiscal years, and how has this affected BOP‘s ability to manage its
growing inmate population?
Costs for key operations to maintain basic services, such as those for
inmate medical care and utilities, have exceeded the funding levels
requested in the President‘s budget over the past five fiscal years,
and this has limited BOP‘s ability to manage its growing inmate
population.
* From fiscal years 2004 through 2008, the funding levels requested in
the President‘s budget for BOP have been insufficient to cover annual
cost growth for maintaining existing services, including inmate medical
care and utilities. Moreover, population adjustment funding”necessary
to cover expenses associated with housing a growing inmate population
in BOP-operated facilities”has not consistently been included in the
President‘s budget, with BOP receiving no funding adjustments in some
years.
* As a result, BOP has faced funding gaps in its operations account
that has left it with limited flexibility to manage its continually
growing inmate population.
Objective 3–Costs to Maintain Key Operations and Accommodate a Growing
Inmate Population Have Exceeded Funding Levels Requested in the
President‘s Budget:
BOP‘s annual cost growth to maintain key operations exceeded annual
funding adjustments requested in the President‘s budget from fiscal
years 2004 through 2008. For example, during this time, costs for non-
salary inmate medical care and utilities exceeded funding levels by
about $131 million and $55 million, respectively. BOP attributed the
cost growth to inflation and inmate population growth.[Footnote 22]
Medical care costs: From fiscal year 2004 through 2008, BOP‘s annual
non-salary inmate medical care costs increased by about $146.5 million.
In contrast, during this period, the President‘s budget requested
funding cost adjustments for non-salary inmate medical care totaling
about $15.4 million.
Objective 3–Costs to Maintain Key Operations and Accommodate a Growing
Inmate Population Have Exceeded Funding Levels Requested in President‘s
Request:
Utilities costs: From fiscal year 2004 through 2008, BOP‘s annual
utilities costs increased by a total of $87 million. In contrast,
during this period, the President‘s budget requested funding cost
adjustments for utilities costs totaling about $31.6 million.
* Table 3 compares the rates of BOP‘s average annual cost growth for
non-salary inmate medical care and utilities to average rates of annual
funding adjustments requested in the President‘s budget, from fiscal
year 2004 through 2008.
Table 3: Objective 3: Historical Cost Growth Has Exceeded Funding
Adjustments in the President‘s Request:
Inmate medical care (non-salary):
Average annual rate of cost growth incurred by BOP, fiscal years 2004
through 2008: 8.7%;
Average annual rate of funding growth in President‘s budget request,
fiscal years 2004 through 2008: 0.9%.
Utilities:
Average annual rate of cost growth incurred by BOP, fiscal years 2004
through 2008: 9.8%;
Average annual rate of funding growth in President‘s budget request,
fiscal years 2004 through 2008: 3.2%.

[End of table]
Objective 3–Costs to Accommodate a Growing Inmate Population and
Maintain Staffing Levels Have Exceeded Funding Adjustments Requested in
the President‘s Budget, According to BOP:
In some years, the President‘s request for BOP has included funding
adjustments for marginal costs associated with inmate population growth
in existing BOP facilities.[Footnote 23] However, BOP budget officials
reported that this cost adjustment has not included necessary funding
to hire additional correctional officers to maintain inmate to
corrections staff ratios and effectively manage the new population.
* For example, the most recent institution population adjustment
request, in fiscal year 2009, included $17.1 million to house a
projected net increase of 1,807 inmates in existing BOP facilities.
[Footnote 24]
* In fiscal year 2009, BOP reported an inmate to corrections officer
ratio of about 10 to 1 (the number of inmates supervised per
corrections officer).
* BOP budget officials reported that BOP would need to hire 180
additional corrections officers to maintain this ratio for the 1,807
new inmates. However, according to salary and benefits cost assumptions
provided by BOP budget officials, the staffing portion of the
adjustment provided funding equivalent to staffing 46 additional
corrections officers.
Objective 3–Because BOP‘s Operations Funding Has Not Kept Pace with
Annual Growth, BOP Continues to Face Challenges Managing its Growing
Inmate Population:
When BOP has not received funding to cover operational cost increases
it has incurred, in some years BOP had used S&E funding planned for
other areas to cover these costs.
* Though one of BOP‘s highest priorities is to increase staffing levels
of corrections officers, BOP officials report using S&E funds in fiscal
years 2008 and 2009 initially planned for hiring additional officers to
instead cover base operations cost increases related to inmate medical
care, utilities, and personnel salary and benefit adjustments that have
been unfunded in the President‘s budget requests.
* In the President‘s fiscal year 2010 budget request, $70 million is
included as a line item for additional BOP staffing. However, BOP
officials reported that this funding, if received, is to be used, in
part, to cover existing employees‘ mandatory pay and benefit increases,
and other operations cost increases.
Objective 3–BOP Has Limited Flexibility in Managing Funding Gaps:
As with any other DOJ component, BOP‘s budget requests are governed by
standard DOJ and OMB budget development guidance.
* For example, DOJ budget development guidance for fiscal years 2008
and 2009 instructed components to limit cost growth for current
services to no more than 4 percent greater than prior year levels.
* DOJ reported that the 4 percent cap guidance is a general instruction
given to all components but recognizes that BOP is different because
its costs are less discretionary. Furthermore, DOJ reported that it did
not automatically reject budget submissions from components that
exceeded the cap, but instead required components to submit substantive
information to justify need.
* DOJ reported that OMB does not automatically provide funds for
inflationary cost increases. DOJ cited OMB policy stating that
inflationary adjustments for discretionary costs (such as utilities)
can include some, all, or no allowance for inflation. DOJ officials
reported that OMB typically does not include general inflationary
adjustments that DOJ submits on behalf of BOP when it formulates the
President‘s request.
* However, DOJ has reported to OMB that, if faced with funding
shortfalls similar to what BOP has faced in its operations budget,
other DOJ components could reduce operations, implement across-the-
board hiring freezes, and implement policy changes that would reduce
costs. However, with almost all of its S&E costs fixed,[Footnote 23]
DOJ reported that BOP has limited flexibility in these areas, and has
already implemented significant reductions to programs, such as
streamlining and centralizing administrative functions to eliminate
2,300 positions.
Conclusions:
In each of the last 2 fiscal years, BOP has needed additional funding
to meet its operating costs.
* However, we found that BOP's cost estimation methods either met or
substantially met GAO‘s cost estimating best practices.
* Further, BOP officials report, and DOJ officials acknowledged, that
BOP has already implemented significant reductions in programs by
eliminating positions and centralizing administrative functions.
* In addition, the current level of overcrowding within BOP facilities
presents an already serious safety challenge. Given BOP‘s unique
responsibility for managing this population, it has limited discretion
when costs for key operations exceed funding levels.
In light of these circumstances, BOP's budget cost estimation practices
could be strengthened in two ways:
* First, although BOP, like other DOJ agencies, is not required to
report the extent to which actual costs may be expected to vary from
cost estimates, we have identified the provision of an uncertainty
analysis as a best practice. If BOP identified its level of cost
estimation confidence and provided this information to DOJ, DOJ could
more fully understand the range of potential costs”and the potential
need for more funding”if estimating assumptions for key cost drivers,
such as inmate population growth, do not hold true.
* Second, by improving documentation of all steps for developing its
cost estimate, BOP would be better positioned to recreate its estimates
in the event of attrition within its budget office among those who have
developed initial cost estimates.
Recommendations:
To improve transparency in BOP‘s cost estimation process, as well as
DOJ‘s annual budget formulation and justification process, and to
provide DOJ with more detailed information to consider when
deliberating its budget proposal for BOP, we recommend that the
Attorney General of the United States take the following two actions:
* instruct the BOP Director to require the BOP budget staff to conduct
an uncertainty analysis quantifying the extent to which operations
costs could vary due to key cost assumptions changing and submit the
results along with budget documentation to DOJ so that DOJ could be
aware of the range of likely costs and associated confidence levels;
and;
* instruct the BOP Director to require the BOP budget staff to improve
documentation of calculations used to estimate its costs.
Agency Comments:
* We provided a draft of this report to DOJ and BOP for review and
comment. We also verbally described our findings and proposed
recommendations to DOJ and BOP officials in a meeting on August 31,
2009. Additionally, we received technical comments from DOJ and BOP,
which we incorporated where appropriate.
* DOJ and BOP generally agreed with the findings. DOJ and BOP will
formally review our recommendations when we submit our final product in
fall 2009.
* We made several requests to meet with OMB, but we were unable to
schedule a meeting during our review.
Appendix I–GAO‘s 12 Step Cost Estimating Practices:
Initiation and research:
Your audience, what you are estimating, and why you are estimating it
are of the utmost importance:
* Define the estimate's purpose;
* Develop the estimating plan.
Assessment:
Cost assessment steps are iterative and can be accomplished in varying
order or concurrently.
* Define the program;
* Obtain the data;
* Determine the estimating structure;
* Identify ground rules and assumptions;
* Develop the point estimate and compare it to an independent cost
estimate.
Analysis:
The confidence in the point or range of the estimate is crucial to the
decision maker. Analysis, presentation, and updating the estimate steps
can lead to repeating previous assessment steps.
* Conduct sensitivity analysis;
* Conduct a risk and uncertainty analysis;
* Document the estimate.
Presentation:
Documentation and presentation make or break a cost estimating decision
outcome.
* Present estimate to management for approval;
* Update the estimate to reflect actual costs/changes.

Appendix II: Comments from the Department of Justice, Federal Bureau of
Prisons:
U.S. Department of Justice:
Federal Bureau of Prisons:
Office of the Director:
Washington, DC 20534:
November 4, 2009:
David C. Maurer, Director:
Homeland Security & Justice Issues:
U.S. Government Accountability Office:
Seattle, WA 98104:
Dear Mr. Maurer:
The Bureau of Prisons (BOP) appreciates the opportunity to formally
respond to the Government Accountability Office's draft report entitled
Bureau of Prisons: Methods for Cost Estimation Largely Reflect
Decisionmaking, but Quantifying Risks Would Enhance Decisionmakinq. We
have completed our review of the information reflected in the report
and offer the following comments.
First, we concur with the GAO assessment and its findings that the BOP
process is "well defined", and that the data and estimates are "well
documented, accurate and credible". Furthermore, we agree with GAO that
funding gaps in the BOP operations account have left the BOP "... with
limited flexibility to manage its continually growing inmate
population." Finally, we concur with the two GAO recommendations as
explained below.
Recommendation 1: Instruct the BOP Director to require the BOP budget
staff to conduct an uncertainty analysis quantifying the extent to
which operations costs could vary due to changes in key cost
assumptions and submit the results along with budget documentation to
DOJ so that DOJ could be aware of the range of likely costs and BOP's
associated confidence levels.
Response: The BOP agrees with this recommendation. To increase
transparency, BOP believes that including the results of uncertainty
analysis in the budget document will provide all decisionmakers (DOJ,
OMB, and the Congress) better context for decisionmaking. The BOP
already provides in its Buildings and Facilities Budget a range of
potential project costs, which alerts the decisionmaker to potential
cost fluctuations such as those we have seen in the past few years. The
BOP looks forward to working with the GAO and learning more about the
analysis program they recommend.
The BOP will accomplish this recommendation with its 2012 budget cycle
beginning in the Spring Call, and if time permits, the BOP will work
with the DOJ and OMB to incorporate it into the President's 2011
Budget.
Recommendation 2: Instruct the BOP Director to require the BOP budget
staff to improve documentation of calculations used to estimate its
costs.
Response: The BOP agrees with this recommendation. To increase
transparency, it is critical that the reader/evaluator of the budget
request be provided sufficient information to understand how the
mandatory costs (i.e., medical, utility, food expenses) were derived
and how capacity and staffing changes will need to be adjusted
accordingly.
The BOP's corrective action is to include its multi-year population
projection table (Budget year + 5) and corresponding crowding table
which demonstrate how the request supports the projected population and
how it tracks with the growth. In addition, pertinent annualization and
inflation factors from BOP supporting documentation will be included to
make the budget request more transparent and easier to understand.
Finally, consistent with the discussion in the GAO report, the BOP
proposes to add historical spending information graphics for mandatory
expenses such as pay increases, medical, utilities and food costs. This
would provide additional context and insight for the reader.

remaining inmates were housed primarily in contract confinement (i.e.,
facilities and halfway houses, operated by private contractors or
state/local governments).

[5] The Salaries and Expenses account includes sub-accounts covering
costs for staffing, inmate medical care, food, and utilities. From
fiscal years 1999 through 2008, these expenses comprised about 90
percent of BOP's budget--in fiscal year 2009, staffing costs for
employee salaries accounted for about 60 percent of the Salaries and
Expenses account. The Buildings and Facilities account has sub-accounts
covering costs for design and construction of new facilities and
modernization and repair of existing facilities.
[6] BOP officials reported that during years in which a continuing
resolution is in effect, they must use the prior year's budget request
submission to DOJ as the baseline because of delays in the enactment of
the budget.
[7] GAO's Cost Estimating and Assessment Guide identifies 12 practices
that are the basis for effective cost estimation. We associate these
practices with four characteristics: accurate, well documented,
credible, and comprehensive. If followed correctly, these practices
should result in reliable and valid cost estimates that (a) can be
easily and clearly traced, replicated, and updated; and (b) enable
managers to make informed decisions.
[8] Non-salary inmate medical care costs refer to the amount BOP spends
on pharmaceuticals, medical supplies, and outside medical care--
community hospital services and a portion of guard escort service and a
portion of salaries (overtime). In fiscal year 2008, non-salary inmate
medical care and utilities costs were $430.5 million and $234 million,
respectively.

[18] According to BOP, the only new construction funding requested by
the administration since fiscal year 2005 has been for completion of an
ongoing prison project in Mendota, California.
[19] See appendix I for a description of these cost estimating
practices.
[20] Non-salary inmate medical care costs refer to the amount BOP spent
on pharmaceuticals, medical supplies, and outside medical care
(community hospital services and a portion of guard escort service and
a portion of salaries (overtime).
[21] An uncertainty analysis provides a range of costs that span a best
and worst case spread. According to best practices, it is better for
decision makers to know the range of potential costs that surround an
estimate and the reasons behind what drives that range rather than just
having a point estimate from which to make their decision.
[22] In fiscal year 2008, non-salary inmate medical care and utilities
costs were $430.5 million and $234 million, respectively.
[23] Marginal costs include providing security, food, medical care,
clothing, unit management, education, records, and maintenance
associated with additional inmates entering existing BOP facilities.
[24] BOP uses a standard DOJ marginal cost per inmate rate. In fiscal
year 2009, this rate was $9,483.
[25] According to BOP data, in fiscal years 2007 and 2008, 99.5 percent
of BOP‘s S&E budget was fixed”that is, for paying staff salaries, and
providing services to house and care for the inmate population.
