Notes To Condensed Consolidated Financial Statements

Basis of Presentation

In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (which consist solely of normal recurring adjustments unless otherwise disclosed) necessary for fair statement, in all material respects, of the Company’s financial position as of September 30, 2006 and June 30, 2006, and the results of operations for the three months ended September 30, 2006 and 2005, and the cash flows for the three months ended September 30, 2006 and 2005.  The results of operations for the three months ended September 30, 2006 are not necessarily indicative of the results to be expected for the full year.

The financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission.  Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading in any material respect.  These financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company’s latest annual report on Form 10-K.

Comprehensive Income

Comprehensive income, defined as net income and other comprehensive income, for the quarters ended September 30, 2006 and 2005 was $6,542,000 and $4,177,000, respectively.  Other comprehensive income includes foreign currency translation adjustments recorded directly in shareholders’ equity.

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 shares and potential common shares outstanding, determined as follows:

	Three Months Ended September 30,
	2006		2005
Numerator:
Net Income	$	6,518,000	$	3,587,000
Denominator:

Incremental shares issuable upon the exercise of stock options	1,297		4,879
Shares used to compute diluted EPS	4,306,635		4,279,234
Basic and Diluted net earnings per share	$	1.51	$	.84

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

Income Taxes

The effective tax rate for the three months ended September 30, 2006 was 38.2% as compared to 37.8% in the comparable period of the prior year.  The increase was primarily attributable to a new margin tax resulting from recent enactment of Texas state tax legislation.  The legislation repealed the franchise tax previously based on capital or earned surplus and imposes a tax calculated on taxable margin and is now accounted for as an income tax under SFAS 109.

Legal Proceedings

Klotzer, et al. v. International Windows In Time, Inc.

International Aluminum Corporation and certain of its subsidiaries are defendants in the above-referenced lawsuit (Case no. FCS021196) filed in December 2002 in the Superior Court for Solano County, California.  The plaintiffs in the lawsuit are the owners of seven homes in which the Company’s Series 6200 windows are installed.  The same lawyers who represent them in this action have also brought similar class actions against other manufacturers of aluminum windows in California.

In their Third Amended Complaint filed in August 2005, the plaintiffs assert various causes of action, including strict product liability, breach of warranty, and violation of the California Consumer Legal Remedies Act.  The plaintiffs also purport to represent a statewide class of persons who own buildings in California that contain the Company’s Series 6200 horizontal sliding, vertical hung, or fixed aluminum windows manufactured during the period 1993 to the present.  In November 2005, the Court certified the plaintiff class.

According to plaintiffs, the essence of their claims is that the Series 6200 windows leak at the lower corners.  Plaintiffs contend that these leaks are caused by the design and manufacture of the lower corners and voids and gaps in the sealant used in the window corners; and that the leaking windows have damaged parts of the homes in which they were installed.  Plaintiffs also claim that the windows do not perform as warranted and do not perform in compliance with American Architectural Manufacturer’s Association, or AAMA, standards.  The Company denies all of these allegations.

There are approximately 80,000 owners of the Series 6200 windows in the class.  The named plaintiffs seek actual and punitive damages, as well as injunctive and restitutionary relief on their claims, including the cost to remove and replace all of the Series 6200 windows in the class.  The Company denies any liability.

The Company’s insurers have accepted the defense of this lawsuit under reservation of rights.  The scope of the Company’s insurance coverage may depend upon the ultimate disposition of the plaintiffs’ claims.

The Company believes the plaintiffs’ claims are without merit, and it intends to vigorously defend this lawsuit.  The lawsuit is in the discovery phase, and the Company cannot predict its outcome or the extent to which insurance would be available to cover any eventual judgment or settlement in the lawsuit.

Other Matters

The Company is regularly involved in a number of lawsuits and proceedings arising in the ordinary course of its business and operations.  The Company does not expect these matters, individually or in the aggregate, to have a material adverse effect on the Company’s financial condition or results of operations.

Recent Accounting Pronouncements

In June 2006, the FASB issued Financial Interpretation No. 48 (FIN 48), “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109,” which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement No. 109, “Accounting for Income Taxes.”  This Interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken on a tax return.  This Interpretation also provides guidance on de-recognition, classification, interest, penalties, accounting in interim periods, disclosure and transition.  The evaluation of a tax position in accordance with this Interpretation will be a two-step process.  The first step will determine if it is more likely than not that a tax position will be sustained upon examination and should therefore be recognized.  The second step will measure a tax position that meets the more likely than not recognition threshold to determine the amount of benefit to recognize in the financial statements.  This Interpretation is effective for fiscal years beginning after December 15, 2006.  Upon adoption in fiscal 2008 we do not anticipate that FIN 48 will have a material impact on our financial statements.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157(SFAS No. 157), “Fair Value Measurements”.  SFAS No. 157 establishes a framework for measuring fair value and requires expanded disclosures regarding fair value measurements.  This accounting standard is effective for financial statements issued for fiscal years beginning after November 15, 2007.  The Company is currently assessing the impact of SFAS No. 157, but at present does not expect that it will have a material effect on the Company’s results of operations or financial condition.

In September 2006, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 108(SAB No. 108), “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” that requires public companies to utilize a “dual-approach” to assessing the quantitative effects of financial misstatements.  This dual approach includes both an income statement focused assessment and a balance sheet focused assessment.  SAB No. 108 is effective for annual financial statements covering the first fiscal year ending after November 15, 2006.  SAB 108 permits existing public companies to initially apply its provisions either by (i) restating prior financial statements as if the “dual approach” had always been used or (ii) recording the cumulative effect of initially applying the “dual approach” as adjustments to the carrying values of assets and liabilities as of July 1, 2006 with an offsetting adjustment recorded to the opening balance of retained earnings.  Use of the “cumulative effect” transition method requires detailed disclosure of the nature and amount of each individual error being corrected through the cumulative adjustment and how and when it arose.  Adoption of SAB No. 108 will not have a material effect on the Company’s results of operations or financial condition.

In September 2006, the FASB issued Staff Position (FSP) AUG AIR-1, “Accounting for Planned Major Maintenance Activities.”  FSP AUG AIR-1 addresses the accounting for planned major maintenance activities. Specifically, the FSP prohibits the practice of the accrue-in-advance method of accounting for planned major maintenance activities.  FSP AUG AIR-1 is effective for fiscal years beginning after December 15, 2006.  Upon adoption in fiscal 2008, the Company does not expect FSP AUG AIR-1 will have an impact on the Company’s results of operations or financial condition.

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Results of Operations

General Overview

International Aluminum Corporation (“Company”) is an integrated manufacturer of quality aluminum and vinyl products for use in commercial and residential applications.  Our marketing brands are recognized leaders in their respective markets.  Operations are conducted throughout North America, with headquarters in Monterey Park, California.  The Company is organized into three business segments, Commercial Products, Residential Products and Aluminum Extrusion.  Our performance is dependent to a significant extent upon levels of new construction, repair and remodeling for commercial and residential applications in the geographic markets we serve, all of which are affected by such factors as interest rates, consumer confidence and economic outlook.

Net sales increased $12,365,000, or 18.1%, for the quarter ended September 30, 2006 compared to the prior year period.  Cost of sales as a percentage of net sales was 73.5% for the current quarter compared to 77.6% for the prior year period.  Selling, general and administrative expenses increased $1,310,000 for the current quarter compared to the same period last year, although as a percentage of net sales decreased to 13.5% for the current quarter compared to 14.1% last year.

The Company includes product costs, inbound freight, purchasing, receiving, inspection, internal transfer, warehousing and other costs of the Company’s distribution network in cost of goods sold, thereby reducing gross profit by these amounts.  Cost of sales and gross profit as a percent of sales for the Company may not be comparable to those of other companies in our industry, since other companies may record purchasing, warehousing and distribution costs as selling, general and administrative expense.

The contribution to these results by each segment is discussed below.

Commercial Products

Sales of the Commercial Products Group increased $11,171,000, or 35.9%, for the first quarter ended September 30, 2006 compared to the same period last year.  This gain reflects continuing robust commercial construction activity together with increased sales prices and expanded geographic market penetration.

Cost of sales as a percentage of sales was 71.3% for the current quarter versus 75.4% for the same period last year.  Despite experiencing increased aluminum costs and incurring energy surcharges from material suppliers, this Group achieved decreased material cost percentages compared to the same period last year.  Also contributing to the lower cost of sales percentages were decreased labor and overhead cost percentages compared to the same period last year reflecting cost-containment efforts coupled with volume efficiencies as a result of the aforementioned sales increases.

Selling, general and administrative expenses increased $848,000 for the current quarter and as a percentage of sales was 10.9% for the current quarter compared to 12.0% for the same period last year.  This increase was mainly attributable to $707,000 of additional employment and sales representation costs and $106,000 in higher marketing expenditures.

Unaudited

Residential Products

Sales of the Residential Products Group decreased $1,910,000, or 8.5%, for the quarter ended September 30, 2006 compared to the same period last year, as increased sales prices and new product development could not overcome the impact of a decline in new-home construction. The anticipated correction occurring in the residential housing market has caused sales for this Group to decline on a current basis; nonetheless, sales currently remain at what is historically a relatively high level for our market areas.

Cost of sales as a percentage of sales was 71.0% for the current quarter versus 69.6% for the same period last year.  Although material cost percentages were virtually unchanged compared to the prior year period, overhead cost percentages increased due to normally recurring costs being spread over a reduced sales base.

Selling, general and administrative expenses increased $39,000 for the current quarter, although as a percentage of sales increased to 11.6% compared to 10.5% for the same period last year.  Several offsetting factors contributed to these results.  Increased expenses of $85,000 for marketing programs and $115,000 for workers’ compensation and general liability policies, as well as $90,000 for expenses related to a litigation settlement were offset by recognizing proceeds of $344,000 resulting from settlement of a glass industry class-action lawsuit.

Aluminum Extrusion

Sales to outside customers of the Aluminum Extrusion Group increased $3,104,000, or 21.3%, for the first quarter ended September 30, 2006 compared to the same period last year despite experiencing a decrease of 3.8% in tonnage shipped.  Current quarter sales at our California facility increased by $2,849,000, or 37.8%, compared to the prior year period.  Increased selling prices coupled with continued demand from existing and new customers, reflected by a 13.6% increase in tonnage shipped, fueled the gain at this facility.  Current quarter sales at our Texas facility increased by $255,000, or 3.6%, compared to the prior year period as increased selling prices were able to overcome a significant 21.7% decline in tonnage shipped.  Loss of volume due to competitive price pressure, a switch to alternate or off-shore suppliers and customer inventory reduction programs contributed to their tonnage decrease.

Cost of sales as a percentage of sales for the Group, which is dependent on total tonnage shipped, including to our Commercial and Residential Products Groups, was 92.5% for the current quarter compared to 97.4% for the same period last year as both facilities improved upon their prior year results.  Despite the aforementioned decrease in tonnage shipped to outside customers, total tonnage shipped posted a slight gain.  Due to the highly competitive marketplace, selling prices were increased directly in line with the increased cost of aluminum resulting in increased material cost percentages.  Through a combination of increased selling prices and cost-containment efforts, both facilities achieved reductions to labor and overhead costs, and cost percentages, which more than offset the increase in the material cost percentage.

Selling, general and administrative expenses increased $184,000 for the current quarter, although as a percentage of sales declined slightly to 3.4% compared to 3.6% for the same period last year.  The increase reflected higher costs of $95,000 for workers’ compensation policies and $74,000 for employee costs related to attainment of incentive compensation targets.

Corporate

General and administrative expenses increased $239,000 for the first quarter ended September 30, 2006 compared to the same period last year, although as a percentage of consolidated net sales declined slightly to 3.3% compared to 3.5% last year.  The increase reflected higher costs of $146,000 for legal fees and $104,000 for employee costs related to attainment of incentive compensation targets.

The increase in net interest income compared to the prior year resulted from increased funds available for investment combined with higher rates of return.

The effective tax rate for the three months ended September 30, 2006 was 38.2% as compared to 37.8% in the comparable period of the prior year.  The increase was primarily attributable to a new margin tax resulting from recent enactment of Texas state tax legislation.  The legislation repealed the franchise tax previously based on capital or earned surplus and imposes a tax calculated on taxable margin and is now accounted for as an income tax under SFAS 109.

Liquidity and Capital Resources

Working capital at September 30, 2006 stood at $93,589,000, an increase of $5,205,000 from June 30, 2006.  The ratio of current assets to current liabilities was 3.7, which was relatively unchanged from the beginning of the year.

The Company’s projected net capital expenditures for fiscal 2007 remains unchanged from those described in the June 30, 2006 Annual Report to Shareholders.  The Company’s lines of credit also remain unchanged from those described in the June 30, 2006 Annual Report to Shareholders.

In September 2006, the FASB issued Staff Position (FSP) AUG AIR-1, “Accounting for Planned Major Maintenance Activities.”  FSP AUG AIR-1 addresses the accounting for planned major maintenance activities. Specifically, the FSP prohibits the practice of the accrue-in-advance method of accounting for planned major maintenance activities.  FSP AUG AIR-1 is effective for fiscal years beginning after December 15, 2006.  At present  the Company does not expect FSP AUG AIR-1 will have an impact on its results of operations or financial condition.

Unaudited

Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

Fluctuating foreign exchange rates and commodity pricing may impact our earnings.  Our foreign exchange exposure is related to activities associated with our Canadian subsidiaries.  We do not attempt to manage these risks by entering into forward exchange contracts, forward commodity delivery agreements or otherwise.

Item 4.  Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Under Securities and Exchange Commission, or SEC, rules, the Company is required to maintain disclosure controls and procedures designed to ensure that information required in the reports that the Company files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.  As part of the Company’s system of disclosure controls and procedures, we have created a Disclosure Committee, which consists of certain members of the Company’s senior management.  The Company’s disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities and Exchange Act of 1934 is accumulated and communicated to management, including the chief executive officer, chief financial officer and other members of the Disclosure Committee, as appropriate to allow timely decisions regarding required disclosure.

The Company has carried out an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures as of the end of the period covered by this report.  The Company’s management, including the Company’s Disclosure Committee, chief executive officer and chief financial officer, supervised and participated in the evaluation.  Based on the evaluation, the chief executive officer and the chief financial officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in Internal Control Over Financial Reporting

The Company’s evaluation of its internal control over financial reporting during the fiscal quarter to which this report relates identified no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
