PART I

ITEM 1 - BUSINESS

Frontier Financial Corporation ("FFC" or "the Corporation") is a Washington
corporation which was incorporated in 1983 and is registered as a financial
holding company under the Bank Holding Company Act of 1956. As part of a plan of
reorganization consummated following the close of business September 30, 1983,
FFC acquired all of the stock of Frontier Bank (the "Bank"), issuing its common
stock in an exchange for the Bank's common stock on a share-for-share basis. FFC
has two subsidiaries: the Bank, which is engaged in a general banking business
and in businesses related to banking, and FFP, Inc., a nonbank corporation which
leases property to the Bank.

The Bank

Frontier Bank is a Washington state-chartered commercial bank that is a member
of the Federal Reserve System, with its headquarters located in Everett,
Snohomish County, Washington. It was founded in September, 1978 by Robert J.
Dickson and local business persons. The Bank is an "insured bank" as defined in
the Federal Deposit Insurance Act.

The Bank engages in general banking business in the State of Washington,
including the acceptance of demand, time and savings deposits and the making of
loans. As of December 31, 2002, the Bank conducted its business operations out
of 38 offices located in Clallam, Jefferson, King, Kitsap, Pierce, Skagit,
Snohomish, and Whatcom counties, which is the Bank's principal market area. Four
offices are located in Everett, one office each is located in Arlington, Duvall,
Snohomish, Smokey Point, Lake Stevens, Kirkland, Marysville, Lynnwood, Mill
Creek, Mount Vernon, Edmonds, Stanwood, Bothell, Woodinville, Monroe, Lake City
(Seattle), Totem Lake, Tacoma, Kent, Redmond, Burlington, Bellingham and four
offices located in Pierce county in the cities of Sumner, Puyallup, Orting and
Buckley. In addition, the following eight branches are located in Clallam,
Jefferson and Kitsap counties; two branches in Poulsbo, and one each are in
Bainbridge Island, Port Angeles, Port Hadlock, Port Townsend, Sequim and
Silverdale. Acquired in the merger with Interbancorp, Inc. (InterBank) which was
consummated in February 2001, were three branches located in King County in the
cities of Duvall, Kirkland and Totem Lake.

Banking Services

The Bank provides a full range of consumer banking services including savings
accounts, checking accounts, installments and commercial lending, safe deposit
facilities, time deposits and other consumer and business related financial
services. In addition to consumer oriented activities, the Bank maintains a
strong commercial lending program, servicing businesses headquartered in the
Bank's principal market area. At the end of 1983, the Bank began to offer a
discount brokerage service to its customers. In September of 1984, the Bank
opened its Real Estate Division, offering a broad range of home, construction
and commercial long-term financing. The Trust Department opened for business in
March of 1985. This department offers a full array of trust services to its
customers. In May 1988, the Bank opened a Private Banking Office to give
personal service to upscale customers. In August 1989, the Bank acquired,
through a merger, three banking offices of Citizens Bank of Snohomish County,
and a real estate origination department. In January 1991, the Bank opened an
office in Mill Creek, providing a full range of consumer banking services.


                                       1
<PAGE>


In March 1991, the Bank opened an Insurance and Investment Center which markets
annuities, life insurance products, and mutual funds to Bank customers and the
general public. In July 1992, the Bank opened its Stanwood Office. In November
1992, the Bank acquired through merger, Edmonds National Bank, which had one
office. In July 1993, the Bank acquired through merger, The Bank of Northshore,
which had two offices located in Bothell and Woodinville, King County,
Washington. This merger marked the first time the Bank branched outside of
Snohomish County. In October 1993, FFP, Inc. a bank premises holding company
subsidiary, purchased land for construction of the Administrative offices which
were relocated from the Evergreen Way Office. This building was placed in
service in 1995. In June 1995, the Bank opened an office in Monroe, providing a
full range of consumer banking services. In August 1996, the Bank opened the
Lake City Office, (North Seattle) and in December 1996 opened its first office
in Skagit County, in Burlington. In May 1997, the Bank opened an office in
Redmond, Washington. This is the Bank's first office in eastern King County.

In December 1998, the Bank acquired, through merger, the Bank of Sumner, with
four offices, and a real estate origination department. These offices provide a
full range of consumer and commercial banking services. In July 1999, the Bank
opened its Bellingham office, which is the Bank's first office in Whatcom
County. In September 1999, the Bank opened its Mount Vernon office which is the
Bank's second office in Skagit County. In December 1999, FFP Inc., purchased
property and a building two miles south of the current Administrative Building
for the Bank's Operations Center which began use in the second quarter of 2001.
In July 2000, the Bank acquired, through merger, North Sound Bank, with eight
offices, a real estate origination department and a financial services company.
These offices provide a full range of consumer and commercial banking services.
In May 2001, the Bank opened an office in Kent, Washington, which is south of
Seattle.

In February 2001, the Bank acquired, through merger, Inter Bank, with two
operating offices and one office approved but not yet opened, which has
subsequently been opened for business. Additionally, Inter Bank had a real
estate origination office. These offices provide a full range of consumer and
commercial banking services.

Employees

At December 31, 2002, the Bank had 558 full time equivalent employees. The Bank
considers its relations with employees to be good.

Competition

All phases of the Bank's activities are highly competitive. Management believes
that the principal competitive factors affecting the Corporation's markets
include interest rates paid on deposits and charged on loans, the range of
banking products available, and customer service and support. The Bank competes
actively with national and state banks, mutual savings banks, savings and loan
associations, finance companies, credit unions, brokerage houses, and other
financial institutions operating in its service area. Some of these financial
institutions have greater resources than those of the Bank. On December 31,
2002, the Corporation had total assets of $1.944 billion and deposits of $1.561
billion.


REGULATION AND SUPERVISION

To the extent that the following information describes statutory and regulatory
provisions, it is qualified in its entirety by reference to the full text of
those provisions. Also, such statutes, regulations and policies are continually
under review by Congress and state legislatures and federal and state regulatory
agencies. A change in statutes, regulations or regulatory policies applicable to
FFC could have a material effect on the business of FFC.



                                       2

Introduction

FFC, its banking and nonbanking subsidiaries, are subject to extensive
regulation by federal and state agencies. The regulation of bank holding
companies and their subsidiaries is intended primarily for the protection of
depositors, federal deposit insurance funds and the banking system as a whole
and not for the protection of security holders.

As discussed in more detail below, this regulatory environment, among other
things, may restrict FFC's ability to diversify into certain areas of financial
services and pay dividends on its capital stock. It may also require FFC to
provide financial support to its banking subsidiary, maintain capital balances
in excess of those desired by management and pay higher deposit insurance
premiums as a result of the deterioration in the financial condition of
depository institutions in general.

Holding Company Structure

FFC is a Washington corporation which was incorporated in 1983 and is registered
as a bank holding company under the Bank Holding Company Act of 1956 (the "Bank
Holding Company Act"). As part of a plan of reorganization consummated following
the close of business on September 30, 1983, FFC acquired all of the stock of
Frontier Bank (the "Bank"), issuing its common stock in an exchange for the
Bank's common stock on a share-for-share basis. FFC has two subsidiaries: the
Bank, which is engaged in a general banking business and in businesses related
to banking, and FFP, Inc., a nonbank corporation which leases property to the
Bank. Effective October 28, 2000, FFC became a financial holding company.

Source of Strength Doctrine. Under current FRB policy, FFC is expected to act as
a source of financial and managerial strength to its subsidiary bank and, under
appropriate circumstances, to commit resources to support such subsidiary bank.

Capital loans from FFC to its subsidiary bank is subordinate in right of payment
to deposits and certain other indebtedness of the subsidiary bank. In the event
of FFC's bankruptcy, any commitment by FFC to a federal bank regulatory agency
to maintain the capital of a subsidiary bank will be assumed by the bankruptcy
trustee and entitled to a priority of payment.

Depositor Preference. The Federal Deposit Insurance Act ("FDI Act") provides
that, in the event of the "liquidation or other resolution" of an insured
depository institution, the claims of depositors of the institution, including
the claims of the FDIC as subrogee of insured depositors, and certain claims for
administrative expenses of the FDIC as a receiver will have priority over other
general unsecured claims against the institution. If an insured depository
institution fails, insured and uninsured depositors, along with the FDIC, will
have priority in payment ahead of unsecured, nondeposit creditors, including
FFC, with respect to any extensions of credit they have made to such insured
depository institution.

Regulatory Agencies

Bank Holding Company. FFC, as a bank holding company, is subject to regulation
under the Bank Holding Company Act and to inspection, examination and
supervision by the Board of Governors of the Federal Reserve System (Federal
Reserve Board) ("FRB") under the Bank Holding Company Act. As of October 28,
2000, FFC became a financial holding company under the Bank Holding Company Act.


                                       3
<PAGE>


Subsidiary Bank. FFC's subsidiary bank, Frontier Bank, is a Washington
state-chartered commercial bank. Effective October 7, 2002, Frontier Bank became
a member bank of the Federal Reserve System. As a Federal Reserve system member,
Frontier Bank is subject to supervision and examination by applicable federal
and state bank agencies, primarily the Federal Reserve, but also the Federal
Deposit Insurance Corporation ("FDIC") and the Division of Banks of the
Department of Financial Institutions for the State of Washington (the
"Division").

Bank Holding Company Activities

"Financial in Nature" Requirement. As a bank holding company that has elected
also to become a financial holding company pursuant to the Bank Holding Company
Act, FFC may affiliate with securities firms and insurance companies and engage
in other activities that are financial in nature or are incidental or
complementary to activities that are financial in nature. "Financial in nature"
activities include securities underwriting, dealing and market making,
sponsoring mutual funds and investment companies, insurance underwriting and
agency, merchant banking, and activities that the FRB determines from time to
time to be so closely related to banking or managing or controlling banks as to
be a proper incident thereto. A bank holding company that is not also a
financial holding company is limited to engaging in banking and such other
activities as determined by the FRB to be so closely related to banking or
managing or controlling banks as to be a proper incident thereto.

No FRB approval is required for FFC to acquire a company (other than a bank
holding company, bank or savings association) engaged in activities that are
financial in nature or incidental to activities that are financial in nature, as
determined by the FRB. Prior FRB approval is required before FFC may acquire the
beneficial ownership or control of more than 5% of the voting shares or
substantially all of the assets of a bank holding company, bank or savings
association.

If the subsidiary bank of FFC receives a rating under the Community Reinvestment
Act of 1977 of less than satisfactory, FFC will be prohibited from engaging in
new activities or acquiring companies other than bank holding companies, banks
or savings associations.

Interstate Banking. Under the Riegle-Neal Interstate Banking and Branching Act
(Riegle-Neal Act), a bank holding company may acquire banks in states other than
its home state, subject to any state requirement that the bank has been
organized and operating for a minimum period of time, not to exceed five years,
and the requirement that the bank holding company not control, prior to or
following the proposed acquisition, more than 10% of the total amount of
deposits of insured depository institutions nationwide or, unless the
acquisition is the bank holding company's initial entry into the state, more
than 30% of such deposits in the state, or such lesser or greater amount set by
the state.

The Riegle-Neal Act also authorizes banks to merge across state lines, thereby
creating interstate branches. States were permitted for a period of time to opt
out of the interstate merger authority provided by the Riegle-Neal Act and, by
doing so, prohibit interstate mergers in the state. Banks are also permitted to
acquire and to establish de novo branches in other states where authorized under
the laws of those states.

Regulatory Approval. In determining whether to approve a proposed bank
acquisition, federal banking regulators will consider, among other factors, the
effect of the acquisition on competition, the public benefits expected to be
received from the acquisition, the projected capital ratios and levels on a
post-acquisition basis, and the acquiring institution's record of addressing the
credit needs of the communities it serves, including the needs of low and
moderate income neighborhoods, consistent with the safe and sound operation of
the bank, under the Community Reinvestment Act of 1977.

Dividend Restrictions

FFC is a legal entity separate and distinct from its subsidiary bank. Its
principal source of funds to pay dividends on its common stock and debt service
on its debt is dividends from its subsidiary bank. The Bank, by statute, cannot
declare or pay any dividend in an amount greater than its retained earnings
without the approval of the Director of the Division of Banks for the State of
Washington.

Deposit Insurance Assessments

Through the Bank Insurance Fund (BIF), the FDIC insures the deposits of FFC's
depository institution subsidiaries up to prescribed limits for each depositor.
The amount of FDIC assessments paid by each BIF member institution is based on
its relative risk of default as measured by regulatory capital ratios and other
factors. Specifically, the assessment rate is based on the institution's
capitalization risk category and supervisory subgroup category. An institution's
capitalization risk category is based on the FDIC's determination of whether the
institution is well capitalized, adequately capitalized or less than adequately
capitalized. An institution's supervisory subgroup category is based on the
FDIC's assessment of the financial condition of the institution and the
probability that FDIC intervention or other corrective action will be required.

The BIF assessment rate currently ranges from zero to 27 cents per $100 of
domestic deposits. The FDIC may increase or decrease the assessment rate
schedule on a semi-annual basis. An increase in the BIF assessment rate could
have a material adverse effect on FFC's earnings, depending on the amount of the
increase. The FDIC is authorized to terminate a depository institution's deposit
insurance upon a finding by the FDIC that the institution's financial condition
is unsafe or unsound or that the institution has engaged in unsafe or unsound
practices or has violated any applicable rule, regulation, order or condition
enacted or imposed by the institution's regulatory agency.

All FDIC-insured depository institutions must pay an annual assessment to
provide funds for the payment of interest on bonds issued by the Financing
Corporation, a federal corporation chartered under the authority of the Federal
Housing Finance Board. The bonds, commonly referred to as FICO bonds, were
issued to capitalize the Federal Savings and Loan Insurance Corporation. The
FDIC established the FICO assessment rates effective for the first quarter of
2002 at approximately $.0196 per $100 annually for BIF-assessable deposits. The
FICO assessments are adjusted quarterly to reflect changes in the assessment
bases of the FDIC's insurance funds and do not vary depending on a depository
institution's capitalization or supervisory evaluations.

FDIC-insured depository institutions pay an assessment rate equal to the rate
assessed on deposits insured by the Savings Association Insurance Fund.

Securities Registration and Reporting

FFC common stock is registered as a class with the SEC under Section 12(g) of
the Securities Exchange Act of 1934 and thus is subject to the periodic
reporting and proxy solicitation requirements and the insider-trading
restrictions of that Act. The periodic reports, proxy statements and other
information filed by FFC under that Act can be inspected and copied at or
obtained from the SEC's Public Reference Room at 450 Fifth Street, NW,
Washington, D.C. 20549. The public may obtain information on the operation of
the Public Reference Room by calling the SEC at 1-800-SEC-0330. FFC is an
electronic filer with the SEC, and the FFC filings may be obtained at the SEC
website (http://www.sec.gov). In addition, the securities issued by FFC are
subject to the registration requirements of the Securities Act of 1933 and
applicable state securities laws unless exemptions are available.

NASD

FFC common stock is traded on the Nasdaq Stock Market under the symbol FTBK. The
National Association of Securities Dealers ("NASD") is the self-regulatory
organization of the Nasdaq Stock Market. FFC is subject to the rules of the
NASD.

Fiscal and Monetary Policies

FFC's business and earnings are affected significantly by the fiscal and
monetary policies of the federal government and its agencies. FFC is
particularly affected by the policies of the FRB, which regulates the supply of
money and credit in the United States. Among the instruments of monetary policy
available to the Federal Reserve are (a) conducting open market operations in
United States government securities, (b) changing the discount rates of
borrowings of depository institutions, (c) imposing or changing reserve
requirements against depository institutions' deposits, and (d) imposing or
changing reserve requirements against certain borrowing by banks and their
affiliates. These methods are used in varying degrees and combinations to
directly affect the availability of bank loans and deposits, as well as the
interest rates charged on loans and paid on deposits. For that reason alone, the
policies of the FRB have a material effect on the earnings of FFC.

Privacy Provisions of Gramm-Leach-Bliley Act

Under the Gramm-Leach-Bliley Act ("GLB Act"), federal banking regulators are
required to adopt rules that will limit the ability of banks and other financial
institutions to disclose non-public information about consumers to nonaffiliated
third parties. These limitations will require disclosure of privacy policies to
consumers and, in some circumstances, will allow consumers to prevent disclosure
of certain personal information to a nonaffiliated third party. Federal banking
regulators issued final rules May 10, 2000 and compliance was optional until
July 1, 2001. The privacy provisions of the GLB Act will affect how consumer
information is transmitted through diversified financial companies and conveyed
to outside vendors. It is not possible at this time to assess the impact of the
privacy provisions on FFC's financial condition or results of operations.

Disclosure Controls and Procedures

The Sarbanes-Oxley Act of 2002 and related rulemaking by the SEC, which effect
sweeping corporate disclosure and financial reporting reform, generally require
public companies to focus on their disclosure controls and procedures. As a
result, public companies such as FFC now must have disclosure controls and
procedures in place and make certain disclosures about them in their periodic
SEC reports (i.e., Forms 10-K and 10Q) and their chief executive and chief
financial officers must certify in these filings that they are responsible for
developing and evaluating disclosure controls and procedures and disclose the
results of an evaluation conducted by them within the 90-day period preceding
the filing of the relevant report, among other things.

Future Legislation

Various legislation, including proposals to substantially change the financial
institution regulatory system and to expand or contract the powers of banking
institutions and bank holding companies, is from time to time introduced in the
Congress. This legislation may change banking statutes and the operating
environment of FFC and its subsidiaries in substantial and unpredictable ways.
If enacted, such legislation could increase or decrease the cost of doing
business, limit or expand permissible activities or affect the competitive
balance among banks, savings associations, credit unions, and other financial
institutions. FFC cannot predict whether any of this potential legislation will
be enacted, and if enacted, the effect that it, or any implementing regulations,
would have on the financial condition or results of operations of FFC or any of
its subsidiaries.

THE BANK

GENERAL. Applicable federal and state statutes and regulations governing a
bank's operations relate among other matters, to capital requirements, required
reserves against deposits, investments, loans, legal lending limits, certain
interest rates payable, mergers and consolidations, borrowings, issuance of
securities, payment of dividends (see "Restrictions on Capital Distributions"
below), establishment of branches, and dealings with affiliated persons. The
FDIC has authority to prohibit banks under their supervision from engaging in
what they consider to be an unsafe and unsound practice in conducting their
business.

FFC's subsidiary bank, Frontier Bank, is a Washington state-charted commercial
bank that is a member bank of the Federal Reserve System. All members banks of
the Federal Reserve are required to purchase Federal Reserve stock, and to
comply with the safety and soundness regulations. As a Federal Reserve System
member, Frontier Bank is subject to supervision and examination by applicable
federal and state banking agencies, primarily the Federal Reserve, but also the
FDIC and the Division. The Bank is also subject to regulation and examination by
the FDIC which insures the deposits of the Bank to the maximum extent permitted
by law and by requirements established by the FRB. The federal laws that apply
to the Bank regulate, among other things, the scope of its business,
investments, reserves against deposits, the timing of the availability of
deposited funds and the nature and amount of and collateral for loans. The laws
and regulations governing the Bank generally have been promulgated to protect
depositors and not to protect shareowners of such institutions or their holding
companies.

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA")
requires federal banking regulators to adopt regulations or guidelines in a
number of areas to ensure bank safety and soundness including: internal
controls, credit underwriting, asset growth, management compensation, ratios of
classified assets to capital, and earnings. FDICIA also contains provisions
which are intended to change independent auditing requirements: restrict the
activities of "undercapitalized banks" to borrow from the FRB's discount window:
and require regulators to perform annual on-site bank examinations and set
standards for real estate lending.

LOANS TO ONE BORROWER. The Bank is subject to limitations on the aggregate
amount of loans that it can make to any one borrower, including related
entities. Applicable regulations generally limit loans-to-one borrower to 15 to
20 percent of unimpaired capital and surplus. As of December 31, 2002 the Bank
was in compliance with applicable loans-to-one borrower requirements.

FDIC INSURANCE. Generally, customer deposit accounts in banks are insured by the
FDIC for up to a maximum amount of $100,000. The FDIC has adopted a risk-based
insurance assessment system under which depository institutions contribute funds
to the Bank Insurance Fund ("BIF"), based on their risk.

On September 30, 1996, the Deposit Insurance Fund Act of 1996 ("Funds Act") was
enacted. The Funds Act provides, among other things, for the recapitalization of
the SAIF through a special assessment on all depository institutions that hold
SAIF insured deposits. The one-time assessment was designed to place the SAIF at
its 1.25 reserve ratio goal.


                                       7
<PAGE>


The Funds Act, for the three-year period beginning in 1997, subjects BIF insured
deposits to a Financing Corporation ("FICO") premium assessment on domestic
deposits at one-fifth the premium rate (approximately 1.3 basis points) imposed
on SAIF insured deposits (approximately 6.5 basis points).

Beginning in the year 2000, BIF insured institutions were required to pay the
FICO obligations on a pro-rata basis with all thrift institutions; annual
assessments are expected to equal approximately 2.4 basis points until 2017, to
be phased out completely by 2019. Until further action by the FDIC, BIF premiums
will be maintained at their current level.

Banking regulations are empowered under the Funds Act to prohibit insured
institutions and their holding companies from facilitating or encouraging the
shifting of deposits from the SAIF to the BIF in order to avoid higher
assessment rates. It is expected that Congress will continue to address
comprehensive legislation on the merger of the funds and elimination of the
thrift charter.

The FDIC may terminate the deposit insurance of any insured depository
institution if it determined after a hearing that the institution has engaged or
is engaging in unsafe or unsound practices, is in an unsafe or unsound condition
to continue operations, or has violated any applicable law. The insurance may be
terminated permanently, if the institution has no tangible capital. If deposit
insurance is terminated, the accounts at the institution at the time of the
termination, less subsequent withdrawals, will continue to be insured for a
period of six months to two years, as determined by the FDIC.

CAPITAL ADEQUACY REQUIREMENTS. The FRB and the FDIC (collectively, the
"Agencies") have adopted risk-based capital guidelines for banks and bank
holding companies that are designed to make regulatory capital requirements more
sensitive to differences in risk profiles among banks and bank holding companies
and account for off-balance sheet items. The guidelines are minimums, and the
federal regulators have noted that banks and bank holding companies
contemplating significant expansion programs should not allow expansion to
diminish their capital ratios and should maintain ratios in excess of the
minimums. Failure to achieve and maintain adequate capital levels may give rise
to supervisory action through the issuance of a capital directive to ensure the
maintenance of required capital levels.

The current guidelines require all federally-regulated banks to maintain a
minimum risk-based total ratio equal to 8 percent, of which at least 4 percent
must be Tier 1 capital. Tier 1 capital includes common shareowners' equity,
qualifying perpetual preferred stock, and minority interest in equity accounts
of consolidated subsidiaries, but excludes goodwill and most other intangibles,
gains or losses on available for sale securities and the allowance for losses on
loans. Total capital includes the excess of any preferred stock not included in
Tier 1 capital, mandatory convertible securities, hybrid capital instruments,
subordinated debts and intermediate term preferred stock and the allowance for
losses on loans up to 1.25 percent of risk-weighted assets. The Bank has not
received notice indicating that it will be subject to higher capital
requirements.

Under these guidelines, banks' assets are given risk-weights of 0 percent, 20
percent, 50 percent or 100 percent. In addition, certain off-balance sheet items
are given credit conversion factors to convert them to asset equivalent amounts
to which an appropriate risk-weight will apply. These computations result in the
total risk-weighted assets. Most loans are assigned to the 100 percent risk
category, except for first mortgage loans fully secured by residential property
and, under certain circumstances, residential construction loans (both carry a
50 percent rating).


                                       8
<PAGE>


Most investment securities are assigned to the 20 percent category, except for
municipal or state revenue bonds (which have a 50 percent rating) and direct
obligations of or obligations guaranteed by the United States Treasury or United
States Government Agencies (which have a 0 and 20 percent rating, respectively).

The Agencies have also implemented a leverage ratio, which is equal to Tier 1
capital as a percentage of average total assets less intangibles, to be used as
a supplement to the risk-based guidelines. The principal objective of the
leverage ratio is to limit the maximum degree to which a bank may leverage its
equity capital base. The minimum required leverage ratio for top-rated
institutions is 4 percent, but most institutions are required to maintain an
additional cushion of at least 100 to 200 basis points. Any institution
operating at or near the 4 percent level is expected to have well-diversified
risk, including no undue interest rate risk exposure, excellent asset quality,
high liquidity and good earnings, and in general to be a strong banking
organization without any supervisory, financial or operational weaknesses or
deficiencies. Any institutions experiencing or anticipating significant growth
would be expected to maintain capital ratios, including tangible capital
positions, well above the minimum levels.

PROMPT CORRECTIVE ACTION. Regulations adopted by the Agencies as required by
FDICIA impose even more stringent capital requirements. The regulators require
the FDIC and other Federal Banking Agencies to take certain "prompt corrective
action" when a bank fails to meet certain capital requirements. The regulations
establish and define five capital levels: (1) "well-capitalized", (2)
"adequately capitalized", (3) "undercapitalized", (4) "significantly
undercapitalized", and (5) "critically undercapitalized." To qualify as "well
capitalized" an institution must maintain at least 10 percent total risk-based
capital, 6 percent Tier 1 risk-based capital, and a leverage ratio of no less
than 5 percent. Increasingly severe restrictions are imposed on the payment of
dividends and management fees, asset growth and other aspects of the operations
of institutions that fall below the category of being "adequately capitalized"
(which requires at least 8 percent total risk-based capital, 4 percent Tier 1
risk-based capital, and a leverage ratio of at least 4 percent).
Undercapitalized institutions are required to develop and implement capital
plans acceptable to the appropriate federal regulatory agency. Such plans must
require that any company that controls the undercapitalized institution must
provide certain guarantees that the institution will comply with the plan until
it is adequately capitalized. As of December 31, 2002, the Bank was well
capitalized and maintained a leverage ratio of 9.01 percent, a risk-based Tier 1
capital ratio of 9.58 percent, and a risk-based total capital ratio of 10.83
percent.

In August of 1995, the Federal Banking Agencies adopted a final rule
implementing the portion of Section 305 of FDICIA that requires the banking
agencies to revise their risk-based capital standards to ensure that those
standards take adequate account of interest rate risk. Effective September 1,
1995, when evaluating the capital adequacy of a bank, the Federal Banking
Agencies' examiners will consider exposure to declines in the economic value of
the bank's capital due to changes in interest rates. A bank may be required to
hold additional capital for interest rate risk if it has a significant exposure
or a weak interest rate risk management process.

RESTRICTIONS ON CAPITAL DISTRIBUTIONS. Dividends paid to FFC by the Bank are a
material source of FFC's cash flow. Various federal and state statutory
provisions limit the amount of dividends the Bank is permitted to pay to FFC
without regulatory approval.

FRB policy further limits the circumstances under which bank holding companies
may declare dividends. For example, a bank holding company should not continue
its existing rate of cash dividends on its common stock unless its net income is
sufficient to fully fund each dividend and its prospective rate of earnings
retention appears consistent with its capital needs, asset quality, and overall
financial condition.


                                       9
<PAGE>

If, in the opinion of the applicable federal banking agency, a depository
institution under its jurisdiction is engaged in or is about to engage in an
unsafe or unsound practice (which depending on the financial condition of the
institution, could include the payment of dividends), the agency may require,
after notice and hearing, that such institution cease and desist from such
practice. In addition, the FRB and the FDIC have issued policy statements which
provide that insured banks and bank holding companies should generally pay
dividends only out of current operating earnings.

According to Washington law, the Bank may not declare or pay a cash dividend in
an amount greater than its retained earnings, without the approval of the
Director of the Division of Financial Institutions.

INTERSTATE BANKING AND BRANCHING. The Riegle-Neal Interstate Banking and
Branching Efficiency Act of 1994 ("Interstate Act") generally permits nationwide
interstate banking and branching by relaxing federal law restrictions on
interstate banking and providing general authorization for interstate branching.
Subject to certain state laws, such as age and contingency laws, the Interstate
Act allows adequately capitalized and adequately managed bank holding companies
to purchase the assets of out-of-state banks. Additionally, since June 1, 1997,
the Interstate Act permits interstate bank mergers subject to these state laws,
unless the home state of either merging bank has "opted-out" of these provisions
by enacting "opt-out" legislation. The Interstate Act does allow states to
impose certain conditions on interstate bank mergers within their borders; for
example, states may require that the in-state merging bank exist for up to five
years before the interstate merger. Under the Interstate Act, states may also
"opt-in" to de novo branching, allowing out-of-state banks to establish de novo
branches within the state.

In 1996, Washington enacted "opting-in" legislation authorizing interstate
mergers pursuant to the Interstate Act. Accordingly, as of June 6, 1996, an
out-of-state bank holding company may now acquire more than 5 percent of the
voting shares of a Washington-based bank, regardless of reciprocity, provided
such bank or its predecessor has been doing business for at least five years
prior to the acquisition. Further, an out-of-state bank may engage in banking in
Washington if the requirement of Washington's interstate banking statute are
met, and either: (1) was lawfully engaged in banking in Washington on June 6,
1996, (2) resulted from an interstate combination pursuant to Washington law,
(3) resulted from a relocation of a head office of a state bank or a main office
of a national bank pursuant to federal law, or (4) resulted from the
establishment of a savings bank branch in compliance with applicable Washington
law. Additionally, the Director of the Division of Financial Institutions may
approve interstate combinations if the basis for such approval does not
discriminate against out-of-state banks, out-of-state holding companies, or
their subsidiaries.

The agencies recently adopted regulations, under which banks are prohibited from
using their interstate branches primarily for deposit production. The Agencies
have accordingly implemented a loan-to-deposit ratio screen to ensure compliance
with this prohibition.

REGULATORY IMPROVEMENT. In 1994, Congress enacted the Community Development and
Regulatory Improvement Act ("Regulatory Improvement Act"), with the intent of,
among other things, reducing the regulatory burden on financial institutions.
This Act is intended to streamline certain regulatory procedures and relax
certain regulatory compliance requirements. In addition, the Regulatory
Improvement Act specifically directs each federal banking agency to review and
streamline its regulations and written supervisory policies.

FINANCIAL MODERNIZATION. In 1999, the Financial Service Act was enacted which:
(1) repealed historical restrictions on preventing banks from affiliating with
securities firms, (2) broadens the activities that may be conducted by national
banks and banking subsidiaries of holding companies, and (3) provides an
enhanced framework for protecting the privacy of consumers' information. In
addition, bank holding companies may be owned, controlled or acquired by any
company engaged in financially related activities, as long as such company meets
regulatory requirements. To the extent that this legislation permits banks to
affiliate with financial services companies, the banking industry may experience
further consolidation, although the impact of this legislation on FFC and the
Bank is unclear at this time.

Effect of Governmental Policies. The Bank is affected not only by general
economic conditions, but also by the monetary and fiscal policies of the United
States Government and various agencies, particularly the Federal Reserve System.
In its role of implementing its monetary policy, the Federal Reserve Board has
the power to regulate the national supply of bank credit through such methods as
open market operations in the United States Government securities markets,
control of the discount rate on member bank borrowings, and establishment of
reserve requirements against bank deposits. These means are used in varying
combinations and have an influence over the growth of bank loans, investments,
and deposits. They may also affect interest rates charged on loans or paid on
deposits. The nature and timing of future changes in monetary policies and their
impact on the Bank are not predictable. As a consequence of extensive regulation
of commercial banking activities in the United States, the Bank's business is
particularly susceptible to being affected by Federal legislation and
regulations which may have the effect of increasing the cost of doing business
or limiting permissible activities.

FFP, Inc.

On April 4, 1988, the Corporation formed a new subsidiary corporation called
FFP, Inc. The purpose of this corporation is to purchase and lease improved real
property to the Bank. The reason for this approach was to preclude placing
nonearning assets on the books of the Bank or the Corporation. For further
details, please see page 26 of this Form 10-K Report, "Properties." It is
intended that future purchases of real property will be made by FFP, Inc. At
this time, it is not anticipated that FFP, Inc. will engage in any other type of
business.

Washington Banking Company

In April 1996, the Corporation purchased 4.99% of the common stock of Whidbey
Island Bank, located approximately 15 miles west of Everett. Shortly thereafter,
the bank converted to the holding company structure and is now called Washington
Banking Company ("WBC"). Subsequent to the initial investment the Corporation
made application to the Board of Governors of the Federal Reserve System to
purchase up to 9.9% ownership in WBC. Approval was received, and the Corporation
has since purchased a total ownership of 9.0%, as of March 14, 2003. The FRB
approval for further purchases of WBC stock by FFC terminated in December, 1999.
FFC does not anticipate further investment in WBC stock at this time. If FFC
were to seek to increase its ownership in WBC, FRB regulatory approval would
again need to be obtained.

Share Repurchase Program

On September 11, 1999, the FFC Board of Directors adopted a Share Repurchase
Program, authorizing the Corporation to repurchase up to five percent (5%) of
the outstanding shares of its common stock. In March 2000, the Board of
Directors of FFC cancelled its Stock Repurchase Program. On January 23, 2001,
the Corporation approved a new program. On October 17, 2001 the Board authorized
an additional 5%. On October 17, 2002 the Board of Directors authorized to
repurchase an additional 5% of outstanding common stock. Since beginning the
programs, the Corporation has repurchased 1,402,400, 473,500, and 346,800 shares
in 2001, 2002 and year-to-date 2003, respectively. There are 606,050 shares
remaining under the current plan.

Availability of Filings

You may access, free of charge, copies of the following reports of FFC on the
SEC's website at www.sec.gov:

        1) Annual Reports on Form 10-K; and
        2) Quarterly Reports on Form 10-Q.

These documents are posted on the SEC's website, generally within twenty-four
hours after FFC files these documents electronically with the Securities and
Exchange Commission. As these reports are currently available from the SEC's
website, FFC does not currently post its reports on its website, but is willing
to provide electronic or paper copies of its filings (subject to actual copying
costs) upon reasonable request.

Loan Administration

The Bank provides revolving lines of credit to many of its borrowers. Such lines
are approved by the Directors' Loan Committee ("Loan Committee") or other
administrative level committee or person if the amount exceeds the lending units
authorized loan limit.

Credit Review personnel, under the direction of the Credit Administrator,
examine the loan portfolio regularly. Reports are made by the Senior Vice
President/Credit Administrator to senior management and the Directors' Loan
Committee, and follow-up corrective action is monitored. Problem loan reports
are prepared for management review on a regular basis.

Certain problem loans are placed on a nonaccrual basis in conformance with
defined policy. The Loan Committee and other administrative personnel regularly
review information reports on adversely classified and delinquent loans.
Comparative summaries of delinquent loans are also provided on a regular basis
to senior management and to the Board of Directors.

Management closely monitors the adequacy of the loan loss reserve and an
analysis is performed four times a year. The allowance is maintained at a level
deemed sufficient to meet potential losses.

The reviews, examinations and actions described above are in addition to the
periodic examinations by federal and state regulatory agencies, as well as the
Bank's internal audit department and the Bank's outside public accounting firm.

Risk Elements - Impaired Assets

NONACCRUING LOANS

Loans are placed in a nonaccrual status when, in the opinion of management, the
collection of additional interest is doubtful, or when the loan becomes ninety
(90) days past due in principal or interest. When a loan is placed in a
nonaccrual status, all interest previously accrued but not collected is reversed
and charged against interest income. Income on nonaccrual loans is then
recognized only to the extent cash is received and where the future collection
of principal is probable. Accruals are resumed only when the loan is brought
current, and when, in the opinion of management, the borrower has demonstrated
the ability to resume payments of principal and interest on a regular basis. As
a consequence, some of these loans are current in their payments at this time.

IMPAIRED LOANS

Loans are considered impaired when, based on current information and events, it
is probable that the Corporation will be unable to collect all amounts due
according to the contractual terms of the loan agreement, including scheduled
interest payments. For a loan that has been restructured, the contractual terms
of the loan agreement refer to the contractual terms specified by the original
loan agreement, not the contractual terms specified by the restructuring
agreement.

This assessment for impairment occurs when and while such loans are on
nonaccrual, or the loan has been restructured. When a loan with unique risk
characteristics has been identified as being impaired, the amount of impairment
will be measured by the Corporation. If the measurement of the impaired loan is
less than the recorded investment in the loan an impairment is recognized by
creating or adjusting an existing allocation of the allowance for loan losses.


                                       17
<PAGE>

RESTRUCTURED LOANS

In cases where a borrower experiences financial difficulties and the Corporation
makes certain concessionary modifications to the contractual terms, the loan is
classified as a restructured (accruing) loan. Loans restructured at a rate equal
to or greater than that of a new loan with comparable risk at the time of the
contract is modified may be excluded from the impairment assessment and may
cease to be considered impaired.

Delinquent and problem loans are a part of any lending enterprise. When a
borrower fails to make payments, the Bank implements collection activities
commencing with simple past due notices. This then progresses to phone calls and
letters, followed by legal activity when and if necessary. At one month past
due, the loan is tracked and reported as a delinquency.

It is the Bank's practice to discontinue accruing interest on virtually all
loans that are delinquent in excess of 90 days regardless of risk of loss,
collateral, etc. Some problem loans which are less than 90 days delinquent are
also placed into nonaccrual status if the success of collecting full principal
and interest in a timely manner is in doubt and some loans will remain in
nonaccrual even after improved performance until a consistent timely payment
pattern is exhibited and/or timely performance is considered to be reliable.

On the following table the dollar amount of loans past due 90 days or more
whether accruing or not, past due, restructured loans and other real estate
owned as a percentage of total loans and other real estate owned (OREO) was
1.14%, .78%, and .31%, for year-end 2002, 2001 and 2000, respectively. These
loans have a variety of situations, some of which may lead to foreclosure or
involve a bankruptcy case and while some of these loans are in active legal
collection processes, others are under active repayment plans and may continue
payment as the borrower's financial situation improves. The year-end 2000
balance of $4.0 million was comprised of 30 loans. The year-end 2001 balance of
$11.5 million was comprised of 60 loans. One loan accounts for $2.5 million of
the year-end nonaccrual balances and including this a total of $4.9 million (26
loans) was comprised of loans acquired from the Bank's most recent merger.

At year-end 2002, this amount consists of 32 loans ranging in size from $3.1
million to nominal amounts. Efforts are continuing to collect these loans with
many involving some measure of legal action. Ninety percent of these loans are
secured by real estate and, while there is always some risk of loss present,
management feels it is not substantial as a proportion of the amount of such
loans.

Other Real Estate Owned

OREO is carried at the lesser of book value or market value. The costs related
to completion, repair, maintenance, or other costs of such properties, are
generally expensed with any gains or inadvertent shortfalls from the ultimate
sale of OREO being shown as other income or expense.

OREO totals ended the year with a balance of $6.5 million representing .34% of
total assets. This is down from the third quarter of .37% as of September 30,
2002 but up from the previous year ending total of .04%. While management
believes the amount of OREO is relatively modest, the increase over previous
year-end balance is an indication of challenges presented by uncertain economic
conditions. The increase, however, does reflect the transition of troubled loans
through an orderly collection process. As of December 31, 2002 OREO assets
consisted of nine properties. Six of these properties are residential lot
developments. The remaining three properties include a completed commercial
retail structure, a 3-unit condo project, and a 4.5 acre undeveloped commercial
land site. All of the described properties are being activity marketed. Two of
these properties are under agreements to sell and are expected to close within
the first quarter of 2003.

Certain other loans, currently in nonaccrual, are in the process of foreclosure
and there is a likelihood these foreclosures will be completed and the loans
will then become OREO. This is viewed as an ordinary part of the collection
process and efforts are constantly underway to reduce and minimize such
nonperforming assets.

Summary of Loan Loss Experience

The allowance for loan losses is the amount, which, in the opinion of
management, provides adequate protection in the event of loan losses. This
analysis is performed quarterly and reviewed by senior management to determine
the adequacy of the reserve. The analysis takes into consideration current
economic trends both on a national and local level. It includes careful
consideration of delinquency rates and trends for special loan categories
including commercial, personal and real estate related loans by geographic
location.

The following table provides an analysis of net losses by loan type for the last
five years at December 31:

The provision for loan losses decreased $7.3 million in 2002, or 53.7%;
increased $12.6 million in 2001, or 1,250.5%, and decreased $1.3 million, or
55.6% in 2000.

While the provision was down in 2002 it was historically higher than in years
prior to 2001. This is due to a weaker Northwest economy, which caused net
charge-offs to reach $4.5 million for the year. With a reserve ratio of 1.70% to
total loans at year-end, the reserve exceeded that of 1.67% at year-end 2001.
Due to one loan, which surfaced in the fourth quarter of 2001, the provision
increased to $13.6 million from $1.0 million in 2000.

Allocation of Allowance for Possible Loan Losses

Based on certain characteristics of the portfolio, potential losses can be
anticipated for major loan categories. In the following table, the allowance for
possible loan losses at year-end, for the last five years, has been allocated
among major loan categories based primarily on their historical net charge-off
experience, along with consideration of factors such as quality, volume,
anticipated economic conditions and other business considerations.

</TABLE>



Historical net charge-offs are not necessarily accurate indicators of future
losses since net charge-offs vary from period to period due to economic
conditions and other factors that cannot be accurately predicted. Thus, an
evaluation based on historical loss experience within individual loan categories
is only one of many factors considered by management in evaluating the adequacy
of the overall allocation.

In addition, regulatory agencies, as an integral part of their examination
process, periodically review the estimated losses on loans. Such agencies may
require the Bank to change the allowance based upon their judgment at the time
of their examination. It is the Bank's policy to be in compliance with all
accounting and regulatory standards related to loan loss reserves and all
accounting policies promulgated by GAAP.

Determination of the Reserve for Loan Losses - Qualitative Factors

The loan portfolio is separated by quality and then by loan type. Loans of
acceptable quality are evaluated as a group, by loan type, with a specific
reserve percent assigned to the total loans in each type, but unallocated to any
individual loan. Conversely, each adversely classified loan is individually
analyzed, to determine a "worst case" loss. A valuation allowance is also
assigned to these adversely classified loans, but at a higher percent due to the
greater risk of loss. For those loans where the "worse case" loss is greater
than the background percentage, the greater amount is specifically allocated to
the reserve.

Setting the level of loan loss reserve includes consideration of subjective
factors in addition to historical loss rates. Actual historical results indicate
that Frontier may have an excess of the necessary reserves required. Our
analysis and calculations take into consideration the inherent risks of a loan
portfolio such as loan types, current and expected economic conditions, industry
data for loan losses within different business cycles, growth of the loan
portfolio, as well as other factors, and management believes that the reserve is
adequate based upon those inherent risks. Loan concentrations, quality, terms
and basic underlying assumptions remained substantially unchanged during the
period.

The analysis/formula for computing the allowance for possible loan losses was
further refined in 2001 and is consistent with SEC Accounting Bulletin No. 102,
Selected Loan Loss Allowance Methodology and Documentation Issues, dated July 6,
2001. From time to time estimated loss factors on certain types or categories of
loans may be changed and/or loans may be sorted into more or different
categories base on similar characteristics and perceived risk profiles by loan
type or industry.


                                       22
<PAGE>



Loan concentrations, quality, terms and basic underlying assumptions remained
substantially unchanged during the period. The actual loan loss reserve as a
percentage of total loans has declined over the last five years, mainly due to
mergers with institutions which had a lower reserve comparably, and due to loan
portfolio quality.

Effects of Changing Interest Rates

The year 2002 saw three decreases in the Prime rate, down to 4.50%. At year-end,
approximately 43% of the loan portfolio represented variable rate loans,
however, 30% of these loans had not yet reached their floor. This helped lessen
the negative impact of declining yield on the portfolio, which dropped to 8.24%
from 9.09% the previous year. However, due to the effect of lower rates on the
deposit side of the balance sheet, the cost of deposits declined to 3.03% from
4.68% a year earlier. This enabled the Corporation to increase the net interest
margin to 5.38% from 4.90% and year earlier.

Concentrations of Credit

The Bank concentrates its lending activities in the following principal areas:
installment, commercial, real estate commercial, real estate construction, and
residential. As of December 31, 2002, these categories accounted for
approximately 2.8%, 18.3%, 44.9%, 26.0% and 8.0% respectively. This mix was
relatively unchanged compared to previous years.

The most significant portion of the loan portfolio consists of commercial real
estate. The portfolio consists of a wide cross-section of retail, small office,
warehouse, and industrial type properties. These loans are secured by first
trust deeds with maturities from 3 to 10 years and original loan to value ratios
generally from 65% to 75%. A substantial number of these properties are owner
occupied. While the Bank has significant balances within this lending category,
management believes that its lending policies and underwriting standards are
sufficient to minimize risk even during these uncertain economic times. Our
lending activities have avoided those real estate sectors that have been most
impacted by the economic slump. As an example, loans to hotel/motel operations
comprise less than 2.6% of the loan portfolio, and Class A properties are an
insignificant portion. Management closely monitors the effects of current and
expected market conditions and other factors that may influence the repayment of
these loans.

The chart below indicates the amount of those loans, and as a percent of total
loans for the period:

Levels of, and Trends in, Delinquencies and Nonaccruals

Nonperforming loans and other real estate increased in 2002 million to $19.0
million, from $12.2 million in 2001. Management monitors delinquencies monthly
and reports are prepared for the Board of Directors review. Delinquencies for
the commercial, personal, real estate and credit lines categories are charted
separately when presented to the Board. The current level represents a 56%
increase by dollar amount from the previous year. This increase reflects the
slowing economy of the Northwest and it is difficult to predict when economic
activity will return to its normal pattern.

Trends in Volume and Terms of Loans

Average loans for the year 2002 was $1.601 billion, representing an increase of
$76.9 million, or 5% over the average balance for 2001. Average loans for 2001
totaled $1.524 billion representing an increase of $196.5 million, or 14.8%
increase over 2000 average loans outstanding. Loans did show favorable increases
throughout 2002 with most of the activity occurring during the third quarter.
However growth did not reach levels achieved during previous years. Management
believes the decreased rate of growth is a reflection of continuing economic
constraints impacting the viability of the region.

Conclusion of Qualitative Factors

The allowance for loan losses is the amount, which, in the opinion of
management, is necessary to absorb inherent loan losses regardless of source.
Management's evaluation of the adequacy of the allowance is based on the market
area served, local economic conditions, the growth and mix of the portfolio and
their related risk characteristics. Based upon actual historical loan loss rates
the loan loss reserve may appear to be somewhat larger than might be necessary,
however our analysis includes subjective factors that cause us to believe the
reserve is adequate, but not unduly conservative.

ITEM 14 - CONTROLS AND PROCEDURES

     (a)  Evaluation of Disclosure Controls and Procedures: An evaluation of the
          Registrant's disclosure controls and procedures (as defined in section
          13(a) - 14(c) of the Securities Exchange Act of 1934 (the "Act")) was
          carried out under the supervision and with the participation of the
          Registrant's Chief Executive Office, Secretary/Treasurer and several
          other members of the registrant's senior management with the 90-day
          period preceding the filing date of this annual report. The
          Registrant's Chief Executive Officer and Secretary/Treasurer concluded
          that the Registrant's disclosure controls and procedures as currently
          in effect are effective in ensuring that the information required to
          be disclosed by the Registrant in the reports it files or submits
          under the Act is (i) accumulated and communicated to the Registrant's
          management (including the Chief Executive Officer and
          Secretary/Treasurer) in a timely manner, and (ii)recorded, processed,
          summarized and reported within the time periods specified in the SEC's
          rules and forms.

     (b)  Changes in Internal Controls: In the quarter ended December 31, 2002,
          the Registrant did not make any significant changes in, nor take any
          corrective actions regarding, its internal controls or other factors
          that could significantly affect these controls.

          Disclosure Controls and Internal Controls. Disclosure controls are
          procedures that are designed with the objective of ensuring that
          information required to be disclosed in FFC's reports filed under the
          Securities Exchange Act of 1934 (Exchange Act) is recorded, processed,
          summarized and reported within the time periods specified in the
          Securities and Exchange Commission's (SEC) rules and forms. Disclosure
          controls are also designed with the objective of ensuring that such
          information is accumulated and communicated to our management, as
          appropriate to allow timely decisions regarding required disclosure.
          Internal Controls are procedures which are designed with the objective
          of providing reasonable assurance that (1) transactions are properly
          authorized; (2) assets are safeguarded against unauthorized or
          improper use; and (3) transactions are properly recorded and reported,
          all to permit the preparation of financial statement in conformity
          with generally accepted accounting principles.



                                       29
<PAGE>


          Limitations on the Effectiveness of Controls. FFC's management does
          not expect that our disclosure controls or our internal controls will
          prevent all error and all fraud. A control system, no matter how well
          conceived and operated, can provide only reasonable, not absolute,
          assurance that the objectives of the control system are met. Further,
          the design of control system must reflect the fact that there are
          resource constraints, and the benefits of controls must be considered
          relative to their costs. Because of the inherent limitations in all
          control systems, no evaluation of controls can provide absolute
          assurance that all control issues and instances of fraud, if any,
          within FFC have been detected. These inherent limitations include the
          realities that judgments in decision-making can be faulty, and that
          breakdowns can occur because of simple error or mistake. Additionally,
          controls can be circumvented by the individual acts of some persons,
          by collusion of two or more people, or by management override of the
          control. The design of any system of controls also is based in part
          upon certain assumptions about the likelihood of future events, and
          there can be no assurance that any design will succeed in achieving
          its stated goals under all potential future conditions; over time,
          controls may become inadequate because of changes in conditions, or
          the degree of compliance with the policies or procedures may
          deteriorate. Because of the inherent limitations in a cost-effective
          control system, misstatements due to error or fraud may occur and not
          be detected.
