To Our Shareholders

On a slight increase in sales, income from continuing operations rose to $4,426,000 or $1.04 per share for the year, up sharply from the $1,485,000 or $.35 per share income from continuing operations for fiscal 2002.  Sales revenues were $192,549,000 versus the $191,429,000 attained in fiscal 2002.  Net income for the year, including a $1,697,000 loss from discontinued operations, was $2,729,000 or $.64 per share versus a loss of $7,983,000 or $1.88 per share for fiscal 2002.  Fiscal 2002 included losses from discontinued operations of $1,533,000 and a $7,935,000 write-down of impaired goodwill resulting from the adoption of SFAS 142 (see notes 8 and 12 to the accompanying financial statements).

Residential Products

Fiscal 2003 was a year of recovery for our Residential Products Group.  The refocusing of our marketing efforts towards better serving our dealer network was reflected in significantly increased revenues and dramatically improved operating income.  Sales for this product segment increased to $53,586,000, up 21% from fiscal 2002.  From essentially a breakeven position in fiscal 2002, operating income increased to just short of $8.6 million in fiscal 2003.  Fiscal 2002’s results were negatively impacted by a six month long labor strike at our South Gate, California facility and by our no longer supplying high volume, low margin, high maintenance cost big-box retailers.

Late in the fiscal year your Board of Directors made the decision to discontinue the operations of International Window-Colorado.  Since its acquisition in late calendar year 1998 Window-Colorado had not performed up to expectations and recently had incurred losses at an accelerated pace.  Although the closure resulted in our incurring a significant loss from discontinued operations for the year, we have been able to substantially reduce forecasted group capital expenditure requirements for fiscal 2004 by the transfer of major equipment items to our other facilities.

Although the overall economy has shown signs of weakness, interest rates continue at low levels.  New home construction is running at a rate not seen in well over a decade and home improvement spending continues at a rapid pace.  As we move forward in fiscal 2004 we plan on building on the success of fiscal 2003.

Commercial Products

While the residential markets remained generally robust throughout the year, the same cannot be said for the commercial construction arena.  Sales for this product segment declined 10% from fiscal 2002 which was in itself down more than 5% from the preceding year.  Operating income for the group declined 37.5% to $6,782,000 from fiscal 2002’s operating income of $10,862,000.  The commercial construction industry continued to face several constraints – a general sense of caution arising from the fragile economy, high vacancy rates for commercial properties and the sharply diminished fiscal health of the federal and state governments. Market conditions were very similar to those which existed in the late 80’s and early 90’s.  As commercial construction declined, competitive pressure forced sharply lower prices in order to maintain market share thereby significantly eroding margins.

5

We continue to expand our product offerings to meet the new testing protocols for high wind-zone hurricane prone regions.  What originally encompassed three counties in Southern Florida has now grown to nearly the entire Eastern seaboard around the Gulf states through Texas.  The events of September 11th have intensified demand for blast resistant products for institutional and government buildings.  Also under development are a thermal door line for the extreme Northern marketing areas and a single hung window line to complement the projected, fixed and casement window product lines introduced last year.

Extruded Products

Our Extruded Products Group continues to suffer from reduced demand and extremely competitive pricing. Total tonnage shipped to all customers, including intercompany, remained stable for the year.  Net tonnage shipped to outside customers increased approximately 13% over fiscal 2002 while revenues increased only 8% due to price competition.  A very high percentage of our total volume is directed to the architectural building products so until there is improvement in the commercial building environment we anticipate little improvement in net operating results.  During the past year our emphasis has been on pursuing new business while at the same time stringently controlling costs as evidenced by the near $2 million drop in operating loss on a $2.8 million drop in total revenues.

Financial Condition

We continue to maintain an extremely strong financial condition with no long-term debt and working capital exceeding $60 million at yearend.  Having completed an extensive three year $28 million capital expenditure program in fiscal 2002, capital expenditures for fiscal 2004 are projected at $3,500,000, up from the $2,800,000 expended during 2003 but still well below our fiscal 2003 non-cash depreciation charges of nearly $7 million.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Significant Changes in Results of Operations

2003 vs. 2002

Net sales for fiscal 2003 increased by $1,120,000 or 0.6% from fiscal 2002.  Included is a $9,234,000 or 20.8% increase by the Residential Products Group.  In addition to higher levels of new home construction and home improvement remodeling, this increase reflects continued recovery of revenues lost due to last year’s trade union strike at our South Gate, California facility as well as replacing sales volume formerly directed to large home improvement centers.  During the prior year the Residential subsidiaries ceased serving as a stocking supplier for these stores that we previously supplied on a regional basis.  Last year sales to large home improvement centers amounted to 9.0% of Residential segment sales compared to only 2.2% for the current year.  Sales of the Aluminum Extrusion Group increased by $3,051,000 or 7.9% when compared to last year.  Net tonnage shipped, particularly in the area served by our Texas facility, increased by 12.5%.  Although the U.S. market for aluminum extrusions remains sluggish, the Texas facility has benefited from expanded geographic market penetration.  This Group continues to experience strong pressure on pricing.  Sales of the Commercial Products Group declined by $11,165,000 or 10.3% when compared to last year, reflective of the continued soft commercial construction market coupled with increased competitive conditions.

Gross profit increased to 18.4% of sales in 2003 as compared to 17.8% in 2002.  The Residential Products Group achieved significantly decreased material, labor and overhead cost percentages compared to the prior year, reflecting the substantially higher sales volume and the continued recovery from prior year’s strike related

8

inefficiencies.  The Aluminum Extrusion Group also experienced decreased cost percentages as production efficiencies gained from the higher tonnage offset lower per unit sales prices.  Partially offsetting these decreases were higher cost percentages incurred at the Commercial Products Group due to lower sales prices resulting from an increasingly competitive marketplace.  The heightened competition for the reduced number of major projects during this year has especially impacted our United States Aluminum facility in Texas.

Selling, general and administrative expenses decreased by $3,595,000 to 14.8% of sales in fiscal 2003 as compared to 16.7% in fiscal 2002.  Excluding a $631,000 gain on the sale of a former operating facility that was recognized during the first quarter last year, the overall decrease would have been $4,226,000.  Of this decrease, $1,958,000 is attributable to retrospective workers’ compensation policies which provided income of $1,064,000 in fiscal 2003 compared to expense of $894,000 in fiscal 2002.  This swing results from anticipated refunds of previously expensed premiums due to favorable changes in actual and projected claim activity.  The $2,268,000 remainder of the decrease primarily reflects reduced employment and advertising costs as well as the prior year containing some additional costs for strike related security and legal services.

Net interest expense decreased compared to the prior year reflecting lower utilization of our foreign lines of credit.

The effective tax rate increased to 35.7% in fiscal 2003 compared to 23.1% last year.  The prior year was abnormally low due to available tax credits offsetting a lower income base.

2002 vs. 2001

Net sales for fiscal 2002 decreased by $15,914,000 or 7.7% from fiscal 2001.  The economic slowdown has been felt to varying

9

degrees at all of our operating groups.  Included is an $8,470,000 or 16.0% decrease by the Residential Products Group.  A prolonged trade union strike at our South Gate, California facility limited our ability to maintain normal delivery schedules to our customers in the territory serviced from this location.  This led directly to the loss of a large home improvement chain that was supplied on a regional basis and at mid-year had accounted for 14% of residential group sales.  Strike related service, quality, and delivery problems also resulted in some customers temporarily shifting to alternative suppliers during the heart of the strike.  The strike terminated in March with an unconditional offer to return to work.  Sales for the Commercial Products Group declined $5,926,000 or 5.2%.  Most all of the North American marketing areas experienced declines as the softening in the commercial construction industry continued to take its toll.  Sales for the Aluminum Extrusion Group decreased $1,518,000 or 3.8% when compared to last year as they experienced continued pressure on volume and prices.  Although overall group sales were down, demand strengthened during the last half of the year in the area served by our Texas facility.

Gross profit decreased to 17.8% of sales in 2002 as compared to 19.3% in 2001.  Several factors contributed to this decline.  Due to the aforementioned strike, the Residential Products Group incurred higher costs due to production inefficiencies resulting from the hiring and training of replacement personnel.  In addition, higher labor and overhead costs, including significantly increased utility costs, were incurred at our California extrusion facility as their decline in overall volume increased unit cost of production.  An increase in overall labor costs also reflects a significant swing from last year’s recovery to additional expense this year for current year workers’ compensation claims.

10

Selling, general and administrative expenses increased to 16.7% of sales in fiscal 2002 as compared to 15.4% in fiscal 2001.  The increase reflects additional expense for retrospective workers’ compensation adjustments for prior year claims and strike related high security and legal costs. Partially offsetting these costs was a reduction in employment related costs and the discontinuance of goodwill amortization (see Note 12).

Net interest expense decreased compared to the prior year reflecting lower utilization of our domestic line of credit.

The effective tax rate decreased to 23.1% in fiscal 2002 compared to 34.8% last year.  This decline reflects available tax credits offsetting a lower income base.

Liquidity and Capital Resources

Working capital at June 30, 2003 was $62,929,000 compared to $58,057,000 at June 30, 2002 and $66,097,000 at June 30, 2001.  The ratio of current assets to current liabilities was 4.6 at the end of 2003 compared to 4.6 at the end of 2002 and 4.4 at the end of 2001.  The Company continues to be in excellent position to meet its short-term operating and discretionary cash requirements.  Funds in excess of current operating requirements are invested in short-term interest-bearing instruments.

Capital expenditures for property, plant and equipment of approximately $2,847,000 in 2003, $11,848,000 in 2002 and $7,712,000 in 2001 were financed through internal cash flow and cash reserves.  Cash flows include proceeds for sales of excess facilities of $2,450,000 in fiscal 2003, $1,655,000 in fiscal 2002 and $3,060,000 in fiscal 2001.  The Company projects net capital expenditures of $3,500,000 for fiscal 2004.  These expenditures are for expansion of production capacity as well as normal recurring capitalized replacement items.

11

The Company anticipates financing these expenditures through internal cash flow and cash reserves.

The Company had $20,000,000 in available credit at the end of 2003 under a short-term borrowing arrangement with a domestic bank.

The Company’s financial condition remains strong.  The Company believes that its cash, other liquid assets, operating cash flows and borrowing capacity, taken together, provide more than adequate resources to fund ongoing operating requirements and future capital expenditures related to the expansion of existing businesses.

Critical Accounting Policies

The summary of Accounting Policies within the Notes to the Consolidated Financial Statements includes the significant policies and procedures used in the preparation of the Company’s consolidated financial statements.  The following is a discussion of each of the Company’s critical accounting policies:

Revenue Recognition

Sales are recognized when products are shipped or when services are provided assuming no significant Company obligations remain and the collection of related receivables is probable.  Revenue recognition on product sales is not subject to significant estimates, as the Company has not experienced significant product returns.

Valuation of Receivables

The Company maintains allowances for doubtfulaccounts for estimated losses resulting from theinability of its customers to make requiredpayments.  The Company performs ongoing creditevaluations of its customers.  If the financialcondition of the Company’s customers were todeteriorate, resulting in an impairment of theirability to make payments, additional allowances maybe required.  Changes in the credit worthiness ofcustomers, general economic conditions and otherfactors may

12

impact the level of future write-offs.

Valuation of Inventory

The Company periodically reviews inventory items and overall stocking levels to ensure that adequate reserves exist for inventory deemed obsolete or excessive.  In making this determination, the Company considers historical stocking levels, recent sales of similar items and anticipated demand for these items.  Changes in factors such as customer demand, new product offerings and other matters could affect the level of inventory obsolescence in the future.

Current and Pending Accounting Changes

In November 2002, the FASB issued Financial Interpretation No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantee of Indebtedness of Others” (FIN 45).  The disclosure requirements are effective for financial statements of interim or annual periods ending after December 15, 2002.  The impact of such adoption did not have a material effect on the Company’s financial statements.  See Note 11 for additional information.

In January 2003, the FASB issued Financial Interpretation No. 46, “Consolidation of Variable Interest Entities” (FIN 46).  FIN 46 is an interpretation of Accounting Research Bulletin 51, “Consolidated Financial Statements”, and addresses consolidation by business enterprises of variable interest entities (VIE’s).  The Company does not hold any interest in VIE’s and therefore the adoption of this interpretation will not impact the Company’s consolidated financial statements.  See Note 11 for additional information.

In January 2003, the FASB issued SFAS No. 148, “Accounting for Stock-Based Compensation-Transition and Disclosure, an amendment of FASB Statement No. 123.” SFAS No. 148 provides alternative methods of

13

transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. It also requires disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. SFAS No. 148 is effective for annual and interim periods beginning after December 15, 2002. As the Company has elected not to change to the fair value based method of accounting for stock-based employee compensation, the adoption of SFAS No. 148 will not impact the financial condition or results of operations.

The Company applies APB Opinion 25 and related interpretations in accounting for stock options granted to employees and, accordingly, does not recognize compensation cost for grants whose exercise price equals the market price of the stock on the date of grant.  There would have been no change to reported net income and earnings per share amounts had the Company elected to recognize compensation cost based on the fair value of the options granted at the grant date as prescribed by SFAS No. 123, “Accounting for Stock-Based Compensation”, due to the lack of option grants during the last five years, the typical vesting period of the Company’s options.

In May 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity”.  As the Company has not issued such instruments adoption of this statement will not have an impact on reported results.  See Note 11 for additional information.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1.  Significant Accounting Policies and Procedures

Description of Business and Principles of Consolidation

International Aluminum Corporation (the Company) is an integrated building products manufacturer of diversified lines of quality aluminum and vinyl products.  The consolidated financial statements include the accounts of the Company and its domestic and foreign subsidiaries.  All significant intercompany transactions and accounts have been eliminated in consolidation.  Certain reclassifications of prior year information were made to conform to the current presentation.

Revenue Recognition

Sales are recognized when products are shipped or services are provided assuming no significant Company obligations remain and the collection of related receivables is probable.

Estimates and Assumptions

The preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes.  Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and marketable securities with original maturities of three months or less.

Foreign Currency Translation

Assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at year-end exchange rates and revenues and expenses are translated at average rates prevailing during the year.  Local currency is considered to be the functional currency.  Translation adjustments are deferred into accumulated other comprehensive income, a separate component of shareholders’ equity.  Foreign currency transaction gains and losses are included in results of operations as incurred.

Depreciation and Amortization

Depreciation and amortization are provided over the estimated useful lives of the assets (up to 40 years for buildings and 3 to 20 years for machinery and equipment) or the remaining terms of the leases, whichever is shorter, using the straight-line method for financial reporting purposes and accelerated methods for tax purposes.

The excess of the purchase price over the underlying book value of the companies acquired is classified as “Costs in excess of net assets of purchased businesses”.  Upon adoption of FAS No. 142 in fiscal 2002, the amortization of these costs was discontinued.  At June 30, 2003

21

the related amount of $1,171,000 had accumulated amortization of $566,000.  At June 30, 2002 the related amount of $1,745,000 had accumulated amortization of $715,000.  The decrease during 2003 relates to the discontinued operations of International Window-Colorado (see Note 8).

Investment Tax Credits

Investment tax credits are accounted for in the period earned in accordance with the flow-through method.

Long-Lived Assets

Whenever events indicate that the carrying values of long-lived assets including any related goodwill may not be recoverable, the Company evaluates the carrying values of such assets using future undiscounted cash flows.  Management believes that, as of June 30, 2003, the carrying values of such assets are appropriate.

Shipping and Handling Fees and Costs

Shipping and handling charges incurred by the Company are included in Cost of Sales and shipping charges billed to customers are included in Net Sales.

Note 3.  Short-Term Debt and Lines of Credit

The Company has a loan agreement with a domestic bank providing for a $20,000,000 unsecured short-term line of credit. There were no amounts outstanding under the agreement at June 30, 2003 or June 30, 2002.  Additionally the Company’s foreign subsidiaries have loan agreements with foreign banks providing for $1,850,000 in secured short-term lines of credit, at the prevailing Canadian prime interest rate (5.0%).  There was $590,000 outstanding under the foreign agreements at June 30, 2003 and $1,034,000 outstanding at June 30, 2002.

Note 4.  Commitments

The Company is committed under real property lease agreements expiring at various dates to 2008.  Certain of the leases have renewal options for periods up to five years and others provide for rent revisions at various dates.  Under the leases the Company is obligated to pay property taxes, insurance and maintenance.  All facility leases are classified as operating leases.

Real property rental expense was $991,000 in 2003, $1,000,000 in 2002 and $1,065,000 in 2001.  Real property rental commitments are $885,000 in 2004, $670,000 in 2005, $448,000 in 2006, $159,000 in 2007 and $88,000 in 2008.

Note 5.  Stock Options

The Company granted stock options for the purchase of common stock to certain executive and managerial employees under the Company’s 1991 Stock Option Plan, whose expired granting authority has been transferred to the successor plan, the 2001 Stock Option Plan.  Options have an exercise price equal to the market price of the stock on the date of grant, a term of ten years and generally become exercisable over a five-year period.  The Company applies APB Opinion 25 and related Interpretations in accounting for the plan, accordingly, no compensation cost has been recognized for those stock options. There would have been no material change in reported net income and earnings per share had compensation cost been determined based on the fair value at the grant dates as prescribed by SFAS 123, “Accounting for Stock-Based Compensation”.  The transactions for shares under options for the three years ended June 30, 2003 were:

	Outstanding				Exercisable
	Number Of Shares		Weighted-Average Exercise Price		Number Of Shares	Weighted-Average Exercise Price

Available for future grants	389,700

Note 6.  Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding.  Diluted earnings per share is computed by dividing net income by the weighted average common and potentially dilutive common equivalent shares outstanding determined as follows:

	2003	2002	2001
Weighted average shares outstanding used to compute basic EPS	4,244,794	4,244,794	4,244,794
Incremental shares issuable upon the exercise of stock options	—	—	—
Shares used to compute diluted EPS	4,244,794	4,244,794	4,244,794

Incremental shares issuable upon the assumed exercise of outstanding stock options are computed using the average market price during the related period.

Note 7.  Capital Stock

The Company has 500,000 shares of preferred stock authorized, with a $10 par value, of which none is outstanding.  There are 10,000,000 shares of common stock authorized, $1 par value, of which there were 4,244,794 shares outstanding at June 30, 2003 and 2002.

24

Note 8.  Acquisitions and Divestitures

During the fourth quarter of the current year, the Company ceased operations of International Window-Colorado, a vinyl window and door subsidiary, which was a component of the Residential Products segment.  In accordance with SFAS   No.144, International Window-Colorado is accounted for as a discontinued operation, therefore, amounts in the income statements and related notes for all periods shown have been restated to reflect discontinued operations accounting.  Included in International Window-Colorado results for the current year are $1,320,000 of charges related to the write down of various assets, primarily inventory and goodwill.  Related assets held for sale are $144,000 of inventory and $236,000 of machinery and equipment.

During the second quarter of fiscal 2002, the Company ceased operations of Maestro Products, its wood window and door subsidiary, which was a component of the Residential Products segment.  In accordance with SFAS No. 144, Maestro Products was accounted for as a discontinued operation, therefore, amounts in the income statements and related notes for all periods shown have been restated to reflect discontinued operations accounting.  Included in Maestro Products results for the prior year are $1,175,000 of charges related to the write down of various assets, primarily inventory.  Due primarily to favorable results experienced in selling Maestro’s facilities, the Company recognized a pre-tax gain of $176,000 in fiscal 2003 which has also been classified as discontinued operations.  The Company does not anticipate any further activity with respect to Maestro in the future.

Summarized results of the discontinued businesses are shown separately as discontinued operations in the accompanying income statements.  Results of the discontinued operations, in thousands of dollars, are as follows:

	2003			2002			2001

Deferred income taxes result from temporary differences in the recognition of income and expenses for tax and financial statement purposes.  The tax effects of the significant temporary differences that comprise the deferred tax assets and liabilities at yearend are as follows:

	2003		2002
Accounts receivable	$	477,000	$	396,000

Net deferred tax liability	$	6,357,000	$	5,929,000

No provision for U.S. taxes has been made for undistributed earnings of the foreign subsidiaries since it is expected that the major portion of such earnings will continue to be reinvested for an indefinite period.  The Company has foreign net operating loss carryforwards that expire between 2009 and 2010.

27

Note 10.  Segment Information

The Company’s operations are organized and managed by product type.  The Company currently operates in three segments of the building products industry:  Commercial Products, Residential Products and Aluminum Extrusions.  See the front cover for a description of the products of each segment and the back cover for a listing of the subsidiaries of each segment.

The Company uses a portion of its aluminum extrusion production in its Commercial and Residential segments.  Transfers are made at market prices.  Accounting policies for the segments are the same as those described in Note 1. The Company evaluates performance based on operating income or loss before any allocation of corporate overhead, interest or taxes.

The following is significant financial information by operating segment, reconciling to the Company’s totals.

Note 11.  Current and Pending Accounting Changes

In November 2002, the FASB issued Financial Interpretation No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantee of Indebtedness of Others” (FIN 45).  FIN 45 requires that upon issuance of a guarantee, a guarantor must recognize a liability for the fair value of the obligation assumed under a guarantee.  FIN 45 also requires additional disclosures by a guarantor in its interim and annual financial statements about the obligations associated with guarantees issued.  The recognition provisions of FIN 45 are effective for any guarantees issued or modified after December 31, 2002. The disclosure requirements are effective for financial statements of interim or annual periods ending after December 15, 2002.  The impact of such adoption did not have a material effect on the Company’s financial statements.

In January 2003, the FASB issued Financial Interpretation No. 46, “Consolidation of Variable Interest Entities” (FIN 46).  FIN 46 is an interpretation of Accounting Research Bulletin 51, “Consolidated Financial Statements”, and addresses consolidation by business enterprises of variable interest entities (VIE’s).  FIN 46 provides guidance on the identification of, and financial reporting for, entities over which control is achieved through means other than voting rights.  FIN 46 requires an enterprise to consolidate a variable interest entity if that enterprise has a variable interest that will absorb a majority of the entity’s expected losses if they occur, receive a majority of the entity’s expected residual return if they occur, or both. The Company does not hold any interest in VIE’s and therefore the adoption of this interpretation will not impact the Company’s consolidated financial statements.

In January 2003, the FASB issued SFAS No. 148, “Accounting for Stock-Based Compensation-Transition and Disclosure, an amendment of FASB Statement No. 123.” SFAS No. 148 provides alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. It also requires disclosures in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method used on reported results. SFAS No. 148 is effective for annual and interim periods beginning after December 15, 2002. As the Company has elected not to change to the fair value based method of accounting for stock-based employee compensation, the adoption of SFAS No. 148 will not impact the financial condition or results of operations.

The Company applies APB Opinion 25 and related interpretations in accounting for stock options granted to employees and, accordingly, does not recognize compensation cost for grants whose exercise price equals the market price of the stock on the date of grant.  There would have been no change to reported net income and earnings per share amounts had the Company elected to recognize compensation cost based on the fair value of the options granted at the grant date as prescribed by SFAS No. 123, “Accounting for Stock-Based Compensation”, due to the lack of option grants during the last five years, the typical vesting period of the Company’s options.

In May 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity”.  SFAS No. 150 requires classification of financial instruments within its scope as a liability, including financial instruments issued in the form of shares that are mandatorily redeemable, because those financial instruments are deemed to be, in essence, obligations of the issuer.  As the Company has not issued such instruments, adoption of this statement will not have an impact on reported results.

Note 12.  Change in Accounting

The Company adopted SFAS No. 142, “Goodwill and Other Intangible Assets” effective July 1, 2001, which required that existing goodwill be reviewed for impairment using a revised methodology.  The Company completed the transitional impairment test and determined that a $7,935,000 non-cash transition charge was required to reduce goodwill.  The transition charge is reflected as a cumulative effect of an accounting change effective July 1, 2001.
