METHODOLOGIES
INTRODUCTION
Cost segregation studies are conducted
for a variety of reasons (e.g., income tax, financial accounting,
insurance purposes, property tax). For income tax purposes, a cost
segregation study involves the allocation (or reallocation) of the total
cost (or value) of property into the appropriate property classes in
order to compute depreciation deductions. The results of a study are
typically summarized in an accompanying report, although there is no
standard format for either the study or the report.
The methodology utilized in allocating
total project costs to various assets is critical to achieving an
accurate cost segregation study. Some of the more common
methodologies, and their potential drawbacks, are summarized in this
chapter. This discussion should assist the examiner in evaluating
the accuracy of a particular study and in performing a risk analysis
with respect to the depreciation deductions based on that study.

WHAT ARE THE MOST COMMON METHODOLOGIES
UTILIZED FOR COST SEGREGATION STUDIES?
Various methodologies are utilized in
preparing cost segregation studies, including:
1. Detailed Engineering Approach
from Actual Cost Records
2. Detailed Engineering Cost Estimate Approach
3. Survey or Letter Approach
4. Residual Estimation Approach
5. Sampling or Modeling Approach
6. "Rule of Thumb" Approach
Examiners should not necessarily expect
to see these terms mentioned in a study or in a report.
Methodologies will also be described in varying detail in different
reports. However, based on the information in this chapter, an
examiner should be able to recognize the attributes of a given study and
identify the methods or approaches used (and also identify the potential
drawbacks). It should also be noted that other methodologies may
be used, although most are merely derivatives of those enumerated above.

WHAT ARE THE
ATTRIBUTES OF VARIOUS COST SEGREGATION METHODOLOGIES?
The following discussion takes a closer
look at the main components and attributes of each of the methodologies
listed above. Keep in mind that these are the steps normally taken
in the preparation of a cost segregation study. The examiner's
responsibility is to review the steps taken and evaluate the accuracy of
the study, as will be discussed in Chapter 5, "Review and
Examination of Cost Segregation Studies."

1. Detailed
Engineering Approach From Actual Cost Records
The detailed engineering approach from
actual cost records, or “detailed cost approach,” uses costs from
contemporaneous construction and accounting records. In general,
it is the most methodical and accurate approach, relying on solid
documentation and minimal estimation. Construction-based
documentation, such as blueprints, specifications, contracts, job
reports, change orders, payment requests, and invoices, are used to
determine unit costs. The use of actual cost records contributes
to the overall accuracy of cost allocations, although issues may still
arise as to the classification of specific assets.
This approach is generally applied only
to new construction, where detailed cost records are available.
For used or acquired property and for new projects where original
construction documents are not available, an alternative approach (e.g.,
the "detailed engineering cost estimate approach”) may be more
appropriate.
The detailed cost approach typically
includes the following activities:
1) Identify the specific
project/assets that will be analyzed.
2) Obtain a complete listing of
all project costs and substantiate the total project costs.
3) Inspect the facility to
determine the nature of the project and its intended use.
4) Photograph specific property
items for reference. Request previous site photographs that
illustrate the construction progress as well as the condition of the
property before the project began.
5) Review "as-built"
blueprints, specifications, contracts, bid documents, contractor pay
requests, and other construction documentation.
6) Identify and assign specific
project items to property classes (e.g., land, land improvements,
building, equipment, furniture and fixtures, and other items of
tangible personal property).
7) Prepare quantitative
"take-offs" for all materials and use payment records to
compute unit costs.
8) Apply unit costs to each
project component to determine its total cost. Reconcile total
costs obtained from quantitative take-offs to total actual costs.
9) Allocate indirect costs, such
as architectural fees, engineering fees, and permits, to appropriate
assets.
10) Group project items with
similar class lives and placed-in-service dates to compute
depreciation.
The detailed cost approach is the
most time consuming method and generally provides the most accurate cost
allocations. However, the examiner should recognize that the
proper classification and costs of § 1245 property could still be an
issue with this method.

2. Detailed
Engineering Cost Estimate Approach
The detailed engineering cost estimate
approach (or detailed estimate approach) is similar to the detailed cost
approach. The difference is that the detailed estimate approach
estimates costs, rather than using actual costs. This approach is
used when cost records are not available or for an acquisition when the
purchase price must be allocated.
The detailed estimate approach is methodical, relying on solid
documentation and utilizing construction-based documents such as
blueprints, specifications, contracts, job reports, change orders,
payment requests, invoices, appraisals, etc. When estimates are
required, they are based on costing data, either from contractors or
from reliable published sources (e.g., R. S. Means or Marshall Valuation
Service). The sources of estimating data are clearly referenced,
including identification of the specific volume, page, and item number.
Further, the same estimating techniques and unit cost data sources are
used for all of the items that comprise the actual cost.
In essence, the steps for this approach
are the same as the detailed cost approach, except for Step 7 (in which
costs come from contractor estimates or estimating guides).
However, if detailed cost estimates are prepared by qualified
individuals, and the estimates are reconciled to actual costs, then
reasonably-accurate cost allocations are possible.

3. Survey
Or Letter Approach
The survey or letter approach is an
alternative method for estimating costs. In this approach,
contractors and subcontractors are contacted via a survey or letter to
provide information on the cost of specific assets that they installed
on a particular project. These costs are then used in one of the
engineering approaches or in the residual estimation approach (discussed
in the following section). Cost allocation using the survey
approach involves the following steps:
1) Complete Steps 1 – 6 of the
detailed cost approach to identify the specific property items that
require cost estimates. Estimates should be reconciled to an
actual cost if possible [either to an overall project cost or to an
individual system cost (e.g., plumbing, electrical)].
2) Divide property items by
contractor and/or subcontractor.
3) Ask contractors and/or
subcontractors to provide the quantities and prices of specific
property items.
4) Use unit cost estimates
obtained from the surveys to determine and allocate property costs.
In situations where the contractor
provides actual cost data, the allocations may be reasonably reliable.
However, when contractor data is obtained from other sites or projects,
the data may not be comparable or reliable. The amount of detail
provided by different contractors may also vary. The wide
disparity in cost estimation methods dictates the use of caution to
ensure that the total allocated costs do not exceed the actual total
project cost.

4. Residual
Estimation Approach
The residual estimation approach is an
abbreviated method in which only short-lived asset costs (e.g., 5- or
7-year property) are determined. Short-lived asset costs are
added together and then subtracted from the total project cost.
The remaining or “residual” cost is then simply assigned to the
building and/or other long-lived assets. Although this method is
simpler and less time consuming than the engineering approaches, it can
also be less accurate.
It should be recognized that this method
generally does not reconcile project costs. In general, residual
costs are not estimated or checked for reasonableness. A proper
and “reasonable” residual cost should always be determined and then
added back to the total of all short-lived asset costs to check if the
total project cost is reconciled.
It should also be understood that
different estimation techniques for short-lived assets can produce a
skewed result in favor of § 1245 property (e.g., § 1245 property based
on single-unit costs for high quality construction, while the building
is based on gross square footage).

5. Sampling
Or Modeling Approach
The sampling or modeling approach uses a
created model (or template) to analyze multiple facilities that are
nearly identical in construction, appearance and use (e.g., fast food
chains and retail outlets). The use of sampling minimizes
resources and costs compared to conducting studies on all properties.
Typical steps are:
1) Stratify properties by type of
facility (e.g., free-standing facility, mall location, leased or owned
property, etc.).
2) Perform a cost segregation
study on a sampling of properties within each stratum.
3) Based on the results in Step 2,
develop a standard model for each type of facility.
4) Apply the costs derived from
the model(s) to the population on a percentage basis. For
example, the model may indicate that 10% of the project
costs are allocable to 5-year property. This same percentage is
then applied to each facility within the same stratum.
A frequent issue is the accuracy of the
sampling results. In some cases, the sampling method may not be
statistically valid. In addition, a population less than 50 could
limit the accuracy of a sampling technique, unless an appropriate
sampling error is considered. Also, despite the fact that
facilities within certain strata may appear to be very similar,
variations in building codes, geographic location, and material and
labor costs may make it difficult to determine an appropriate model.
Statistical sampling is discussed in more detail in Chapter 5,
"Review and Examination of a Cost Segregation Study," and in
Appendix Chapter 6.5.

6. "Rule
Of Thumb” Approach
Some cost segregation studies are merely
based on a "rule of thumb” approach. In general, this
approach uses little or no documentation and is based on a preparer's
"experience" in a particular industry. For example, a
preparer will estimate § 1245 property as a fixed percentage of project
cost by relying on previously determined “industry averages” (e.g.,
40% for a manufacturing facility). An examiner should view this
approach with caution, since it lacks sufficient documentation to
support its allocation of project costs.

WHAT
METHODOLOGY IS REQUIRED BY THE IRS?
Neither the Service nor any group or
association of practitioners has established any requirements or
standards for the preparation of cost segregation studies. The
courts have addressed component depreciation, but have not specifically
addressed the methodologies of cost segregation studies.
The Service has addressed this issue but
only briefly, i.e., Revenue Ruling 73-410, 1973-2 C.B. 53, Private
Letter Ruling (PLR) 7941002 (June 25, 1979), Chief Counsel Advice
Memorandum 199921045 (April 1, 1999). These documents all
emphasize that the determination of § 1245 property is factually
intensive and must be supported by corroborating evidence. In
addition, an underlying assumption is that the study is performed by
"qualified" individuals or firms, such as those employing
"…personnel competent in design, construction, auditing, and
estimating procedures relating to building construction" (PLR
7941002).
Despite the lack of specific requirements
for preparing cost segregation studies, taxpayers still must
substantiate their depreciation deductions and classifications of
property. Substantiation using actual costs is generally
preferable to the use of estimates. However, in situations where
estimation is the only option, the methodology and the source of any
cost data should be clearly documented. In addition, estimated
costs should be reconciled back to actual costs or purchase price.

SUMMARY AND
CONCLUSIONS
Cost segregation studies are prepared for
a variety of reasons (e.g., income tax, financial accounting, insurance
purposes, property tax), and many different methodologies and procedures
are used. While neither the Service nor any group or association
of practitioners prescribes a specific methodology, there are certain
approaches (e.g., studies based on actual costs or on proper estimation
techniques) that produce more accurate and reliable allocations.
Despite the use of one of these more reliable methods, issues may still
arise with respect to the proper classification of § 1245 property.
Methodologies that yield accurate cost
allocations expedite the Service's review, saving time and resources for
taxpayers, practitioners, and Service examiners alike. A study
that is both accurate and well documented is considered (in this ATG) a
“quality” cost segregation study. The specific characteristics
that comprise a quality study are described in Chapter 4,
"Principal Elements of a Quality Cost Segregation Study and
Report".
