The implementation of the MAR in 2010 will
provide a valuable opportunity for insurers
to assess the effectiveness of their internal
controls and the accuracy of their financial
reporting. Insurers must promptly develop a
strategy for compliance with the MAR if they
have not done so already. A set of corporate
norms for complying with the new MAR
has yet to develop, but actuaries have the
knowledge and skills to assist in many aspects
of the process and can help determine the set
of best practices moving forward.

feAture Story
A standard set of practices for complying
with the MAR has not been established yet,
but many of the new rules require or can
benefit from the type of analysis actuaries
already perform for insurance companies.
The purpose of the MAR, which went into
effect in most states for the accounting period
beginning January 1, 2010, is to facilitate
more effective surveillance by state insurance
departments of the financial condition
of insurers. The MAR accomplishes this
by requiring annual audited financial
statements, as well as reports on the
effectiveness of internal controls over the
financial reporting process.
As such, the MAR will expand the demand
for both financial statement auditing services
and internal control reporting, two functions
in which actuaries already assist insurance
companies and can provide complementary
or supplementary depth and perspective to
other audit professionals. Because of actuarial
expertise in advising and evaluating insurance
risks, actuaries are uniquely positioned to
evaluate MAR compliance while adhering
to the spirit of the MAR for independence
and disclosure.
financial Statements &
the reserving Process
The first main requirement of the MAR is an
annual audit of insurance company financial
statements. Insurance companies often
involve actuaries in the reserving process, as
loss reserves represent the most substantial
liability carried on the balance sheet of P&C
insurers, according to “The Application
of Fundamental Valuation Principles to
Property/Casualty Insurance Companies” by
Blackburn. Loss reserves are a provision for
insurers’ liability for claims, whether reported
or unreported, on coverage the company has
provided. Sound loss reserves are essential for
maintaining the healthy financial condition
of an insurance company. Although the
loss reserves represent management’s best
estimate, appropriate actuarial methods,
assumptions, and judgment weigh heavily in
deriving and supporting these estimates.
Actuarial involvement is integral in the
estimation of several financial statement items
for insurers including, for example, premium
deficiency reserves and asset valuation reserves
in addition to loss reserves.Actuaries must also
opine on the reasonability of these reserves in
the Statement of Actuarial Opinion (SAO).
A premium deficiency reserve should
be recognized when the unearned premium
reserve and any future installment premiums
on existing policies fall short of anticipated
losses, loss adjustment expenses, commissions
and other acquisition costs, and maintenance
costs of the policies. Future losses and
installment premiums are contingent cash
" ows that depend on many interrelated
factors and are often material in magnitude.
Actuaries are able to better assess these cash
" ows and develop the premium deficiency
reserve, as well as to ensure the reported
numbers are accurate and vetted.
Likewise, the asset valuation reserve is
intended to offset potential credit-related
investment losses on certain invested assets.
Credit-related investment losses can be
estimated with credit models that relate credit
loss to performance, collateral characteristics,
and economic factors like unemployment,
gross domestic product, and interest rates.
Independence in the SAo
Most P&C insurers are already required to
submit a SAO to the regulator each year. The
SAO is not part of the audited financials under
the new MAR per se, but it is supporting
material in the audit process and under the
MAR this requirement can technically be met
by the auditing firm.
Several key drivers of the recent
financial crisis were also prevalent
in the tumult leading to the creation
of the Sarbanes-Oxley Act (SOX)
eight years ago, including a lack
of corporate transparency and a
rash of high profile bankruptcies.
This year many SOX-like public
disclosure rules will take effect
for non-publicly traded insurance
companies. The National Association of Insurance Commissioners (NAIC)
is strengthening its standards for financial solvency and internal controls
through its revised Annual Financial Reporting Model Regulation, more
commonly known as the Model Audit Rule (MAR).
An Expanded Role for Actuaries in the
New Model Audit Rule

However, firms interested in maintaining
real and perceived independence of the opinion
will carefully consider this decision. The SAO
is a formal attestation, made by a qualified
actuary, that the booked reserves represent
a reasonable provision for the unpaid claim
liabilities of the company. Because the purpose
of the MAR (as well as SOX) was to split the
consulting and audit functions, companies
should consider having an external actuary
provide the SAO in the spirit of independence
and of forging new best-practices.
Internal Controls: focus on
Data, Process, & reporting
An insurance company’s financial statements
can only be as good as the rigor of its
internal process for producing and verifying
the components of these statements. The
second main requirement of the MAR is an
evaluation of these internal controls to ensure
that controls exist and function properly.
Evaluators can ask whether the company uses
all available and relevant data in the reserving
process, whether the models are applied
correctly, whether the process has been peer
reviewed, and so forth.
Under the new rules, management
must assert whether its internal control
over financial reporting effectively provides
“reasonable assurance regarding the reliability
of financial statements.” This assertion requires
a diligent effort from management to evaluate
the effectiveness of its internal control systems.
One of the most essential internal controls
for an insurance company is validation of
the models and processes that feed into the
financial reporting function. In particular,
validation of the reserving process is essential
given the significance of reserves to an
insurance company’s financial position. Sound
model validation procedures should re" ect
validation of three key aspects: Data validation,
Process validation and Reporting validation.
Data Validation
Data validation considers the reasonableness
of model assumptions, including model
inputs as well as parameters that require
some judgment in estimation. For example,
two common approaches to estimating
future losses are to use data on paid losses
alone, or to use data on paid losses plus loss
adjustment expenses; the appropriate choice
depends on the context. If a company uses a
method with paid losses alone, an evaluator
who is unfamiliar with the nuances of the
two methods might simply check that the
company actually applies all the paid loss data
to the model, whereas an actuary can advise
the company on when to include the loss
adjustment expenses based on the company’s
modeling needs.
Companies must also ensure that the
inputs are from a reliable source and re" ect
the appropriate segmentation of business, loss
limitation, and other policy terms. Whenever
possible, the data used in the actuarial analysis
should be verified against the company’s
financial statements or statutory annual
statement. In fact, an actuary signing an SAO
is required to reconcile the data with Schedule
P of the statutory annual statement.
Process Validation
Process validation involves checking the
accuracy and proper application of the
mathematics, computer code, and theory
underlying a model. Many different types of
analysts, including actuaries, could conduct a
technical review of a company’s processes to
ensure that any formulas and code function
correctly and perform the intended tasks.
However, companies must also examine the
theory behind a model to assess its suitability
for the particular risk exposure, current
industry environment, and available data;
actuaries have specialized expertise in this
realm. For example, if a computer model uses
two different methods to estimate a given
value,actuaries have the specialized knowledge
to assess whether those two methods are even
relevant for the given context, or whether a
third and fourth method should supplement
or replace the existing methods.
If a given insurer provides several distinct
coverages, the reserving process must take into
account the nuances of each one. For example,
it is common for medical malpractice insurers
to provide death, disability and retirement
(DD&R) coverage as a component of their
claims-made policies. While claims-made
coverage only insures claims filed during the
policy term, DD&R will protect a qualifying
policyholder against claims filed after his or
her medical practice has ended due to death,
disability, or retirement. It is appropriate to
consider different approaches to estimating
the unpaid claim liabilities in each case.
Historical insurance data can be projected
forward to determine the claims-made
reserves, but DD&R reserves must take into
account the age distribution of policyholders,
their mortality and retirement rates, policy
retention rates, and other demographic
information.
reporting Validation
Proper reporting validation involves checking
that results fall within a range of plausible
values and are useful to the end user.
This process requires both expertise and
experience and is best performed by someone
familiar with the way the models work from
start to finish. Scanning the model outputs
for unexpected or unlikely values could help
a company identify problems missed during
a technical review of each model component.
Back-testing can also help a company monitor
the accuracy of previous assumptions and
results. In the course of this process, a
company may identify aspects of the model
that would benefit from future improvements.
Conclusion
The implementation of the MAR in 2010 will
provide a valuable opportunity for insurers
to assess the effectiveness of their internal
controls and the accuracy of their financial
reporting. Insurers must promptly develop a
strategy for compliance with the MAR if they
have not done so already. A set of corporate
norms for complying with the new MAR
has yet to develop, but actuaries have the
knowledge and skills to assist in many aspects
of the process and can help determine the set
of best practices moving forward.
