AXT, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Basis of Presentation

The accompanying condensed consolidated financial statements of AXT, Inc. (“AXT”, the “Company”, “we,” “us,” and “our” refer to AXT, Inc. and all of its consolidated subsidiaries) are unaudited, and have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the year-end condensed consolidated balance sheet data was derived from our audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of our management, the unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, considered necessary to present fairly the financial position, results of operations and cash flows of AXT and our subsidiaries for all periods presented.

Our management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Actual results could differ materially from those estimates.

The results of operations are not necessarily indicative of the results to be expected in the future or for the full fiscal year. It is recommended that these condensed consolidated financial statements be read in conjunction with our consolidated financial statements and the notes thereto included in our ~~2006~~2007 Annual Report on Form 10-K filed with the Securities and Exchange Commission ~~(“SEC”)~~ on March ~~23, 2007 and our Quarterly Report on Form 10-Q filed with the SEC on May 11, 2007.~~

~~Note 2. Discontinued Operations~~

Our condensed consolidated financial statements have been presented to reflect the opto-electronics business as a discontinued operation for all periods presented. Operating results of the discontinued operation are as follows (in thousands):

In the first quarter of 2007, we dissolved the corporation that previously operated our discontinued operations and transferred the cash balance to our continuing operations. Accordingly, we no longer have discontinued operations. In the three and six months ended June 30, 2006, the $2,000 and $3,000, respectively, in income was interest earned on cash balances held in the discontinued operations.

Note 32. Accounting for Stock-Based Compensation

Effective January 1, 2006, we adopted the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), “Share-Based Payment,” (“SFAS 123(R)”). SFAS 123(R) establishes accounting for stock-based awards exchanged for employee services. Accordingly, stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the employee requisite service period. All of our stock compensation is accounted for as an equity instrument. We previously applied Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations and provided the required pro forma disclosures of SFAS No. 123, “Accounting for Stock-Based Compensation”.

We elected the modified prospective transition method for adopting SFAS 123(R). Under this method, the provisions of SFAS 123(R) apply to all awards granted or modified after the date of adoption. The unrecognized expense of awards not yet vested at the date of adoption will be recognized in net income ~~(loss)~~ in the periods after the date of adoption using the same Black-Scholes valuation method and assumptions determined under the original provisions of SFAS No. 123, “ Accounting for Stock-Based Compensation,” as disclosed in our previous quarterly and annual reports.

~~Impact~~The effect of ~~the Adoption of SFAS 123(R)~~

~~Under the modified prospective application transition method as provided by SFAS 123(R),~~ ~~we recorded $91,000 and $186,000 of~~recording stock compensation ~~expense in our unaudited condensed consolidated statements of operations~~ for the three months ended ~~June 30,~~March 31, 2008 and 2007 and 2006, respectively, and $211,000 and $443,000 of stock compensation expense in our unaudited condensed consolidated statements of operations for the six months ended June 30, 2007, and 2006, respectively. We elected not to capitalize any stock-based compensation to inventorywas as of January 1, 2006 when the provisions of SFAS 123(R) were initially adopted. We utilized the Black-Scholes valuation model for estimating the fair value of the stock compensation granted both before and after the adoption of SFAS 123(R). The following table summarizes the compensation expense related to our stock-based compensation planfollows (in thousands, except per share data):

As of ~~June 30, 2007 and 2006,~~March 31, 2008, the total compensation costs related to unvested stock-based awards granted to employees under our stock option plan but not yet recognized was approximately ~~$851,000 and $1.0 million, respectively,~~$1,391,000 net of estimated forfeitures of ~~$60,000 and $44,000, respectively, and will be adjusted for subsequent changes in estimated forfeitures.~~$449,000. This cost will be amortized on a straight-line basis over a weighted-average period of approximately ~~2.2 years.~~2.4 years and will be adjusted for subsequent changes in estimated forfeitures. We elected not to capitalize any stock-based compensation to inventory as of ~~June 30,~~March 31, 2008 and December 31, 2007, ~~and 2006,~~ due to the immateriality of the amount.

The amortization of stock compensation under SFAS 123(R) for the period after our January 1, 2006 adoption is based on the single-option approach.

We estimate the fair value of stock options using a Black-Scholes valuation model, consistent with the provisions of SFAS 123(R), and Securities and Exchange Commission Staff Accounting Bulletin No. ~~107 and our prior period pro forma disclosures of net loss, including stock-based compensation (determined under a fair value method as prescribed by SFAS No. 123).~~107. There were no stock option grants made in the three ~~and six~~ months ended ~~June 30,~~March 31, 2007. The fair value of our stock options granted to employees for the three ~~and six~~ months ended ~~June 30, 2006~~March 31, 2008 was estimated using the following weighted-average assumptions:

The investments include ~~$6.9~~$6.6 million and ~~$7.2~~$6.7 million recorded as restricted deposits on the condensed consolidated balance sheets as of ~~June 30, 2007~~March 31, 2008 and December 31, ~~2006,~~2007, respectively, as a result of the outstanding principal amount on our industrial revenue bonds.

We manage our investments as a single portfolio of highly marketable securities that is intended to be available to meet our current cash requirements. For the three ~~and six~~ months ended ~~June 30,~~March 31, 2008, we had $459,000 in gross realized gains on sales of our available-for-sale securities. For the three months ended March 31, 2007 we had ~~$19,000 and $29,000, respectively,~~$10,000 in gross realized losses on sales of our available-for-sale securities. ~~For the three and six months ended June 30, 2006, we had $0.4 million and $1.4 million, respectively, in gross realized gains on sales of our available-for-sale securities.~~

The gross unrealized losses related to our portfolio of available-for-sale securities were primarily due to a decrease in the fair value of debt securities as a result of an increase in interest rates during ~~2006~~2007 and the first ~~six~~three months of ~~2007.~~2008. We have determined that the gross unrealized losses on our available-for-sale securities as of ~~June 30, 2007~~March 31, 2008 are temporary in nature. We reviewed our investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is temporary include the magnitude of the decline in market value, the length of time the market value has been below cost (or adjusted cost), credit quality, and our ability and intent to hold the securities for a period of time sufficient to allow for any anticipated recovery in market value. The

following table provides a breakdown of our available-for-sale securities with unrealized losses as of ~~June 30, 2007~~March 31, 2008 (in thousands):

Investments in Privately-held Companies

We have made strategic investments in private companies located in China in order to gain access at a competitive cost to raw materials that are critical to our substrate business. (See Note 9). At March 31, 2008 and December 31, 2007, our investments in privately-held companies had a carrying value of $5.1 million and $4.9 million, respectively. The investment balances for the two companies accounted for under the equity method are included in “other assets” in the condensed consolidated balance sheets. We own 25% of the ownership interests in each of these companies.

Fair Value Measurements

On January 1, 2008, we adopted SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”) which defines fair value, establishes a framework for using fair value to measure assets and liabilities, and expands disclosures about fair value measurements. SFAS No. 157 applies whenever other statements require or permit assets or liabilities to be measured at fair value. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007, except for nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis, for which application has been deferred for one year.

The following table summarizes the Company’s financial assets and liabilities measured at fair value on a recurring basis in accordance with SFAS No. 157 as of March 31, 2008 (in thousands):

	Balance as of March 31, 2008		Quoted Prices in Active Markets of Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)

Total	$	37,684	$	14,917	$	22,767

Liabilities	$	—	$	—	$	—

Our financial assets and liabilities are valued using market prices on both active markets (Level 1) and less active markets (Level 2). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily-available pricing sources for comparable instruments. As of March 31, 2008, the Company did not have any assets or liabilities without observable market values that would require a high level of judgment to determine fair value (Level 3 assets).

Items Measured at Fair Value on a Nonrecurring Basis

Certain assets that are subject to nonrecurring fair value measurement are not included in the table above. These assets include equity and cost method investments in private companies. We did not record other-than-temporary impairment charges for either of these investments during the first quarter of 2008.

The final purchase price for ~~sale We recorded a $481,000 market value adjustment after we entered into an agreement with an independent third party purchaser in June 2007 to purchase~~ the property ~~for estimated~~was $5.3 million. We received net proceeds of $5.1 million after deducting ~~estimated commission~~commissions and selling expenses. We ~~expect~~recorded an impairment charge upon the sale ~~to be completed in~~of the ~~third quarter~~property of ~~2007. This property has been classified as “assets held~~$83,000. There was no impairment charge for ~~sale” in~~ the ~~amount of $5.1 million on the condensed consolidated balance sheet as of June 30,~~same three month period ended March 31, 2007.

Note 7.6. Net Income ~~(Loss)~~ Per Share

Basic net income ~~(loss)~~ per common share is calculated by dividing net income ~~(loss)~~ available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income ~~(loss)~~ per common and common equivalent shares include the dilutive effect of common stock equivalents outstanding during the period calculated using the treasury stock method. Common stock equivalents consist of the shares ~~issueable~~issuable upon the exercise of stock options.

Note 9.8. Segment Information and Foreign Operations

Segment Information

We operate in one segment for the design, development, manufacture and distribution of high-performance compound semiconductor substrates and sale of materials. In accordance with SFAS No. 131, “Disclosures About Segments of an Enterprise and Related Information” (“SFAS No. 131”), our chief operating decision-maker has been identified as the Chief Executive Officer, who reviews operating results to make decisions about allocating our resources and assessing our performance. All material operating units qualify for aggregation under SFAS No. 131 due to their identical customer base and similarities in economic characteristics, nature of products and services, and procurement, manufacturing and distribution processes. Since we operate in one segment, all financial segment and product line information required by SFAS No. 131 can be found in the condensed consolidated financial statements.

The investment balances for the two companies accounted for under the equity method are included in “other assets” in the condensed consolidated balance sheets. We own 25% of the ownership interests in each of these companies. These two companies are not considered variable interest entities because:

· ~~both companies have sustainable businesses of their own;~~

·		both companies have sustainable businesses of their own;

·		our voting power is proportionate to our ownership interests;

·		we only recognize our respective share of the losses and/or residual returns generated by the companies if they occur; and

The minority interest for those investments that are consolidated is included inwithin “Other long-term liabilities” in the condensed consolidated balance sheets and inwithin “Other income (expense), net” on the condensed consolidated statements of operations.

We also have investments in two privately-held companies which are accounted for under the cost method as we do not have the ability to exercise significant influence over their operations. As of March 31, 2008 and December 31, 2007, these investments totaled approximately $0.4 million and are included in “other assets” on the condensed consolidated balance sheets.

Note ~~11.~~10. Commitments and Contingencies

Indemnification Agreements

~~Included in our~~

We enter into standard ~~terms and conditions of sale that we enter into~~indemnification arrangements in the ordinary course of ~~business with our customers are standard indemnification arrangements.~~business. Pursuant to these arrangements, we indemnify, hold harmless, and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, generally their business partners or customers, in connection with ~~any claim by a third party that our products violate or infringe~~ any U.S. patent, or any copyright or other intellectual property ~~right.~~infringement claim by any third party with respect to our products. The term of these indemnification ~~provisions~~agreements is generally perpetual ~~from the date of~~anytime after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these agreements is unlimited. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the estimated fair value of these agreements is minimal.

We have entered into indemnification agreements with our directors ~~officers~~ and ~~key employees~~officers that may require us to indemnify our directors ~~officers~~ and ~~key employees~~officers against liabilities that may arise by reason of their status or service as directors or officers, ~~or key employees,~~ other than liabilities arising from willful misconduct of a culpable nature; to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified; and to obtain directors’ and officers’ insurance if available on reasonable terms, which we currently have in place.

Product Warranty

We warrant our products for a specific period of time, generally twelve months, against material defects. We provide for the estimated future costs of warranty obligations in cost of sales when the related revenue is recognized. The accrued warranty costs represent the best estimate at the time of sale of the total costs that we expect to incur to repair or replace product parts that fail while still under warranty. The amount of accrued estimated warranty costs are primarily based on historical experience as to product failures as well as current information on repair costs. On a quarterly basis, we review the accrued balances and update these based on the historical warranty cost trends. The following table reflects the change in our warranty accrual which is included in “accrued liabilities” on the condensed consolidated balance sheets, during the three months ended March 31, 2008 and ~~six months ended June 30,~~ 2007 ~~and 2006~~ (in thousands):

~~Purchase Commitment~~

On February 27, 2007, we entered into an agreement with Recapture Metals Limited of Ontario, Canada (“Recapture”), pursuant to which Recapture will supply our subsidiary in the People’s Repiblic of China with one thousand kilograms per month of 99.99999% pure gallium, during the eighteen month period beginning July 1, 2007. Under the terms of the agreement, we are required to purchase a minimum of eighteen thousand kilograms of gallium, unless the agreement is terminated prior to the expiration of the eighteen month period on December 31, 2008. Our total commitment under this agreement is approximately $7.3 million.

Note ~~12.~~11. Foreign Exchange Transaction Gains/Losses

We incurred foreign currency transaction exchange gains of $189,000 and foreign exchange losses of ~~$246,000 and $47,000~~$44,000 for the three ~~months~~month periods ended ~~June 30,~~March 31, 2008, and 2007, ~~and 2006, respectively. We incurred foreign currency transaction exchange losses of $290,000 and gains of $11,000 for the six months ended June 30, 2007, and 2006,~~ respectively. These amounts are included in other income (expense), net on the condensed consolidated statements of operations.

Note ~~13.~~12. Income Taxes

In July 2006, the Financial Accounting Standards Board (“FASB”) issued Interpretation No. 48 (“~~FIN”~~FIN48”) ~~48,~~ , “Accounting for Uncertainty in Income ~~Taxes”~~Taxes—an interpretation of FASB Statement No. 109),”., FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with SFAS 109. 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 in a tax return. FIN 48 also provides guidance on derecognition of tax benefits, classification on the balance sheet, interest and penalties, accounting in interim periods, disclosure, and transition. We adopted FIN 48 effective January 1, 2007. We recognize interest and penalties related to uncertain tax positions in income tax expense. As of ~~June 30, 2007,~~March 31, 2008, we do not have any gross unrecognized tax benefits, nor any accrued interest and penalties related to uncertain tax positions. As a result of the implementation of FIN 48, we identified $16.4 million in unrecognized tax benefits. This amount decreased the tax loss carryforwards in the U.S. which are fully offset by a valuation allowance. We file income tax returns in the U.S. federal, various states and foreign jurisdictions. We have substantially concluded all U.S. federal and state income tax matters through December 31, 2006.

Note 13. Recent Accounting Pronouncements

In March 2008, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”). SFAS 161 requires companies with derivative instruments to disclose information that should enable financial statement users to understand how and why a company uses derivative instruments, how derivative instruments and related hedged items affect a company’s financial position, financial performance and cash flows. SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. Based on our current

operations, we do not expect that the adoption of SFAS 161 will have a material impact on our consolidated financial position or results of operations.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), “Business Combinations”, (“SFAS 141R”). SFAS 141R establishes the principles and requirements for how an acquirer in a business combination (1) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed and any non-controlling interest in the acquiree, (2) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase and (3) determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. SFAS 141(R) is effective beginning with the Company’s fiscal 2009. The impact of the adoption of SFAS 141(R) on the Company’s results of operations and financial position will depend on the nature and extent of business combinations that the Company completes, if any, in or after fiscal 2009.

In December 2007, the FASB issued SFAS No. 160, “Noncontrolling Interests in Consolidated Financial Statements” (“SFAS 160”). SFAS 160 requires that minority interest be separately reported in the consolidated entity’s equity section and that no gain or loss shall be reported when transactions occur between the controlling interest and the non-controlling interests. Furthermore, the acquisition of non-controlling interest by the controlling interest is not treated as a business combination. SFAS 160 is effective for fiscal years beginning after December 15, 2008. We have not yet evaluated the impact of SFAS 160 on our consolidated financial position, results of operations or cash flows.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an amendment of FASB Statement No. 115” (“SFAS 159”). SFAS 159 expands the use of fair value accounting to many financial instruments and certain other items. The fair value option is irrevocable and generally made on an instrument-by-instrument basis, even if a company has similar instruments that it elects not to measure based on fair value. SFAS 159 is effective for fiscal years beginning after November 15, 2007. We do not have any instruments eligible for election of the fair value option. Therefore, the adoption of SFAS 159 in the first quarter of fiscal 2008 did not impact our consolidated financial position, results of operations or cash flows.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 defines fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods of those fiscal years. In February 2008, the FASB released a FASB Staff Position (FSP FAS 157-2— Effective Date of FASB Statement No. 157 ) which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually) to fiscal years beginning after November 15, 2008. These non-financial items include assets and liabilities such as reporting units measured at fair value in a goodwill impairment test and non-financial assets acquired and liabilities assumed in a business combination. The partial adoption of SFAS 157 as of January 1, 2008 for financial assets and liabilities did not have a material impact on our condensed consolidated financial position, results of operations or cash flows. See Note 3 of the Notes to Condensed Consolidated Financial Statements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This quarterly report on Form 10-Q, including the following sections, contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, particularly statements relating to our expectations regarding results of operations, customer demand, improvements in our product quality, our ability to expand our markets and increase sales, customer qualifications of our products, gross margins, favorable pricing, reliable supply and enhanced sourcing lead-times of raw materials, and our reserve balances. These forward-looking statements are based upon management’s current views with respect to future events and financial performance, and are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those anticipated in such forward-looking statements. Such risks and uncertainties include those set forth under ~~Item 1A~~the section entitled “Risk Factors” below, which identify important factors that could cause actual results to differ materially from those predicted in any such forward-looking statements. We caution investors that actual results may differ materially from those projected in the forward-looking statements as a result of certain risk factors identified in this Form 10-Q and other filings we have made with the Securities and Exchange Commission. Forward-looking statements may be identified by the use of terms such as “anticipates,” “believes,” “estimates,” “expects,” “intends,” and similar expressions. Statements concerning our future or expected financial results and condition, business strategy and plans or objectives for future operations are forward-looking statements.

These forward-looking statements are not guarantees of future performance. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. This discussion should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, ~~2006~~2007 and the condensed consolidated financial statements included elsewhere in this report.

Overview

We are a leading worldwide developer and producer of high-performance compound and single element semiconductor substrates comprising gallium arsenide (GaAs), indium phosphide (InP) and germanium (Ge). We currently sell the following substrate ~~products:~~products in the sizes and for the applications indicated:

Product
Substrates	Diameter	Applications
GaAs (semi-insulating)	2”~~, 4”,~~ to 6”	· Power amplifiers and integrated circuits for wireless handsets
		· Direct broadcast television
		· High-performance transistors
		· Satellite communications

GaAs (semi-conducting)	2”, 3”, 4”	· High brightness LEDs
		· Lasers
		· Optical couplers

InP	2”, 4”3”, 6”4”	· Broadband and ~~Fiber~~fiber optic communications

Ge	2”, 4”	· Satellite and terrestrial solar cells
		· Optical applications

We manufacture compound semiconductor substrates using our proprietary vertical gradient freeze, or VGF, technology. Our in-house VGF technology enables us to add capacity quickly and cost efficiently. We manufacture all of our products in China, which generally has lower costs for facilities, labor and materials.

We also have three majority-owned and two minority-owned joint ventures in China which provide us favorable pricing, reliable supply and enhanced sourcing lead-times for key raw materials which are central to our final manufactured products. These joint ventures produce products including 99.99% pure gallium (4N Ga), high purity gallium, arsenic, germanium, germanium dioxide, paralytic boron nitride (pBN) crucibles and boron oxide. AXT’s ownership interest in these entities ranges from 25% to 83%. We consolidate the three ventures in which we own a majority or controlling financial interest and employ equity accounting for the two joint ventures in which we have a 25% interest. We purchase portions of the materials produced by these ventures for our own use and the joint ventures sell the remainder of their production to third parties.

Revenue increased ~~$7.3~~$7.1 million, or ~~39.0%~~56.7%, to ~~$26.2~~$19.6 million for the ~~six~~three months ended ~~June 30, 2007~~March 31, 2008 from ~~$18.8~~$12.5 million for the same period of ~~2006~~2007 primarily due to our improved ~~product~~ quality, higher customer demands for ~~larger~~six-inch diameter wafers, and an increase in raw material sales. On March 28, 2008, we completed the sale of our Fremont, California facility and received net proceeds of approximately $5.1 million after deducting commissions and selling expenses. As of ~~June 30, 2007,~~March 31, 2008, we had available cash, cash equivalents and short-term investments of ~~$33.7~~$39.4 million, excluding restricted deposits.

~~Recovery of Impairment on Assets Held for Sale~~

During the three months ended June 30, 2007, we benefited from a recovery of impairment on assets held for sale in connection with our adjustment of the fair value of our U.S. property located in Fremont, California, which has been decontaminated and is being prepared for sale, to market value. We recorded a $481,000 market value adjustment after we entered into an agreement with an independent third party purchaser in June 2007 to purchase the property for estimated net proceeds of $5.1 million, after deducting estimated commission and selling expenses. We expect the sale to be completed in the third quarter of 2007. This property has been classified as “assets held for sale” in the amount of $5.1 million on the condensed consolidated balance sheet as of June 30, 2007.

Critical Accounting Policies and Estimates

We have prepared our condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America. As such, we have had to make estimates, assumptions and judgments that affect the amounts reported on our financial statements. These estimates, assumptions and judgments about future events and their effects on our results cannot be determined with certainty, and are made based upon our historical experience and on other assumptions that are believed to be reasonable under the circumstances. These estimates may change as new events occur or additional information is obtained, and we may periodically be faced with uncertainties, the outcomes of which are not within our control and may not be known for a prolonged period of time. The discussion and analysis of our results of operations and financial condition are based upon these condensed consolidated financial statements.

We have identified the policies below as critical to our business operations and understanding of our financial condition and results of operations.

A critical accounting policy is one that is both material to the presentation of our financial statements and requires us to make difficult, subjective or complex judgments that could have a material effect on our financial condition and results of operations. They may require us to make assumptions about matters that are highly uncertain at the time of the estimate, and different estimates that we could have used, or changes in the estimate that are reasonably likely to occur, may have a material impact on our financial condition or results of operations.

We ~~have identified~~believe that the ~~policies below as~~following are our critical ~~to our business operations and understanding of our financial condition and results of operations.~~accounting policies:

Revenue Recognition

We manufacture and sell high-performance compound ~~and single element~~ semiconductor substrates and sell certain raw materials including gallium, germanium dioxide, and pBN crucibles. After we ship our products, there are no remaining obligations or customer acceptance requirements that would preclude ~~recognition of the~~ revenue ~~earned on the sale.~~recognition. Our products are typically sold pursuant to a purchase order placed by our customers, and our terms and conditions of sale do not require customer acceptance. We recognize revenue upon shipment and transfer of title of products to our customers, which is ~~ordinarily~~either upon shipment from our dock, receipt at the customer’s dock, or removal from consignment inventory at the customer’s location, provided that we have received a signed purchase order, the price is fixed or determinable, title and risk of ownership have transferred, collection of resulting receivables is probable, and product returns are reasonably estimable. We do not provide training, installation or commissioning services. Additionally, we do not provide discounts or other incentives to customers.

We provide for future returns based on historical experience, current economic trends and changes in customer demand at the time revenue is recognized.

~~In June 2006, the FASB ratified the consensus reached by the Emerging Issues Task Force (“EITF”) regarding EITF Issue No. 06-03, “~~~~How Taxes Collected from Customers and Remitted to Government Authorities Should be Presented in the Income Statement (That Is, Gross versus Net Presentation)”~~~~. We have historically presented, and will continue to present sales tax, value added tax, and other similar taxes on a net basis, excluding them from revenue.~~

Allowance for Doubtful Accounts

We periodically review the likelihood of collection on our accounts receivable balances and provide an allowance for doubtful accounts receivable primarily based upon the age of these accounts. We ~~typically~~ provide a 100% allowance for receivables from U.S. customers in excess of 90 days and for receivables from customers located outside the U.S. in excess of 120 days. We assess the probability of collection based on a number of factors, including the length of time a receivable balance has been outstanding, our past history with the customer and their creditworthiness.

As of ~~June 30, 2007~~March 31, 2008 and December 31, ~~2006,~~2007, our accounts receivable, net, balance was ~~$9.9~~$16.7 million and ~~$9.7~~$12.1 million, respectively, which was net of an allowance for doubtful accounts of ~~$0.7 million~~$187,000 and ~~$0.1 million,~~$379,000, respectively. ~~The increase in the allowance for doubtful accounts was mainly for our slow-paying customers in Asia.~~ If actual uncollectible accounts differ substantially from our estimates, revisions to the estimated allowance for doubtful accounts would be required, which could have a material impact on our financial results for the period.

Warranty Reserve

We maintain a warranty reserve based upon our claims experience during the prior twelve months. Warranty costs are accrued at the time revenue is recognized. As of ~~June 30, 2007~~March 31, 2008 and December 31, ~~2006,~~2007, accrued product warranties totaled ~~$949,000 and $459,000, respectively. The increase in accrued warranties is attributable to increased claims experienced as well as to an increase in revenue.~~$1.0 million. If actual warranty costs differ substantially from our estimates, revisions to the estimated warranty liability would be required, which could have a material impact on our financial condition and results of operations.

Inventory Valuation

Inventories are stated at the lower of cost or market. Cost is determined using the weighted average cost method. Our inventory consists of raw materials as well as finished goods and work-in-process that include material, labor and manufacturing overhead costs. Given the nature of our substrate products, and the materials used in the manufacturing process, the wafers and ingots comprising work-in-process may be held in inventory for up to two years and three years, respectively, as the risk of obsolescence for these materials is low. We routinely evaluate the levels of our inventory in light of current market conditions in order to identify excess and obsolete inventory, and we provide a valuation allowance for certain inventories based upon the age and quality of the product and the projections for sale of the completed products. As of ~~June 30, 2007~~March 31, 2008 and December 31, ~~2006,~~2007, we had an inventory reserve of ~~$12.7~~$13.5 million and ~~$15.4~~$13.6 million for excess and obsolete inventory, respectively. The majority of this inventory has not been scrapped, and accordingly, may be sold in future periods. If actual demand for our products were to be substantially lower than estimated, additional inventory adjustments for excess or obsolete inventory might be required, which could have a material impact on our business, financial condition and results of operations.

Impairment of Investments

We classify our investments in debt and equity securities as available-for-sale securities as prescribed by Statement of Financial Accounting Standards (“SFAS”) No. 115, “Accounting for Certain Investments in Debt and Equity Securities”. All available-for-sale securities with a quoted market value below cost (or adjusted cost) are reviewed in order to determine whether the decline is other-than-temporary. Factors considered in determining whether a loss is temporary include the magnitude of the decline in market value, the length of time the market value has been below cost (or adjusted cost), credit quality, and our ability and intent to hold the securities for a period of time sufficient to allow for any anticipated recovery in market value.

We invest in equity instruments of privately-held companies for business and strategic purposes. These investments are classified as other assets and ~~other than companies that we consolidate,~~ are accounted for either under the cost method or under the equity method as we do not have the ability to exercise significant influence over their operations. We monitor our investments for impairment and would record reductions in carrying value when events or changes in circumstances indicate that the carrying value may not be recoverable. Determination of impairment is highly subjective and is based on a number of factors, including an assessment of the strength of the investee’s management, the length of time and extent to which the fair value has been less than our cost basis, the financial condition and near-term prospects of the investee, fundamental changes to the business prospects of the investee, share prices of subsequent offerings, and our intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in our carrying value.

Impairment of Long-Lived Assets

We evaluate the recoverability of property, equipment and intangible assets in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” When events and circumstances indicate that long-lived assets may be impaired, we compare the carrying value of the long-lived assets to the projection of future undiscounted cash flows attributable to these assets. In the event that the carrying value exceeds the future undiscounted cash flows, we record an impairment charge against income equal to the excess of the carrying value over the assets’ fair value. Fair values are determined based on quoted market values, discounted cash flows or internal and external appraisals, as applicable. Assets held for sale are carried at the lower of carrying value or estimated net realizable value.

Employee Stock Options

We grant options ~~to purchase our common stock~~ to substantially all management employees and believe that this program helps us to attract, motivate and retain high quality employees, to the ultimate benefit of our stockholders. Effective January 1, 2006, we adopted the fair value recognition provisions of SFAS No. 123 (revised 2004), “Share-Based Payment” (“SFAS

123(R)”), using the modified prospective application transition method. Under this transition method, stock-based compensation cost was recognized in the condensed consolidated financial statements for all share-based payments after January 1, 2006. Compensation cost recognized includes the estimated expense for the portion of the vesting period after January 1, 2006 for share-based payments ~~granted~~ prior to, but not vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS ~~No.~~ 123, “Accounting for Stock-Based Compensation.” We recognize these compensation costs net of an estimated forfeiture rate over the requisite service period of the award, which is generally the vesting term of four years for stock options. Results for prior periods have not been restated, as provided for under the modified prospective application transition method.

As of the date of the filing of this quarterly report, we believe there have been no material changes to our critical accounting policy on employee stock options during the three months ~~and six months~~ ended ~~June 30, 2007~~March 31, 2008 compared to that disclosed in our Annual Report on Form 10K for the fiscal year ended December 31, ~~2006~~2007 filed with the ~~SEC~~Securities and Exchange Commission (“SEC”) on March ~~23, 2007 and our Quarterly Report on Form 10-Q filed with the SEC on May 11, 2007.~~14, 2008. See Note 32 to our condensed consolidated financial statements.

Income Taxes

We account for income taxes in accordance with SFAS No. 109 (“SFAS 109”), “Accounting for Income ~~Taxes”~~ ~~(“SFAS 109”)~~,Taxes,” which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. SFAS 109 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized.

We provide for income taxes based upon the geographic composition of worldwide earnings and tax regulations governing each ~~country, including~~region, particularly ~~the People’s Republic of~~ China. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws, particularly in foreign countries such as ~~the People’s Republic of~~ China.

~~In July 2006, the Financial Accounting Standards Board (“FASB”) issued~~Effective January 1, 2007, we adopted FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income ~~Taxes,~~ Taxes—an interpretation of FASB Statement No. ~~109” (“FIN 48”)~~109. ~~FIN 48 clarifies~~” See Note 12 — “Income Taxes” in the ~~accounting for uncertainty in income taxes recognized in an enterprise’s~~condensed consolidated financial statements ~~in accordance with SFAS 109. 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 in a tax return. FIN 48 also provides guidance on derecognition of tax benefits, classification on the balance sheet, interest and penalties, accounting in interim periods, disclosure, and transition. We adopted FIN 48 effective January 1, 2007. We recognize interest and penalties related to uncertain tax positions in income tax expense. As of June 30, 2007, we do not have any gross unrecognized tax benefits, nor any accrued interest and penalties related to uncertain tax positions. As a result of the implementation of FIN 48, we identified $16.4 million in unrecognized tax benefits. This amount decreased the tax loss carryforwards in the U.S. which are fully offset by a valuation allowance. We file income tax returns in the U.S. federal, various states and foreign jurisdictions. We have substantially concluded all U.S. federal and state income tax matters through December 31, 2006.additional information.

Sales of 5 inch and 6 inch diameter GaAs substrates were $8.0 million for the six months ended June 30, 2007 compared to $6.0 million for the six months ended June 30, 2006. The increase in larger diameter substrate revenue was due to the fact that, while the GaAs device market grew in strength for both cellular and the WLAN (Wide Local Area Network) markets, the compound semiconductor industry has been experiencing capacity constraints, particularly in 6 inch; with our excess capacity, we were able to benefit from the overflow business from our competition.

InP revenue increased $269,000, or 29.6%, to $1.2 million for the six months ended June 30, 2007 from $0.9 million for the six months ended June 30, 2006. The increase in InP revenue was primarily due to a one-time sale of $251,000 indium scrap metal, while InP substrate revenue was flat from customers in the optical networking industry.

Ge substrate revenue increased $738,000, or 360.0%, to $943,000 for the six months ended June 30, 2007 from $205,000 for the six months ended June 30, 2006. The increase in Ge substrate revenue was due to an increase in customers in the People’s Republic of China and to a customer in Germany who has now qualified our product, as demand for photovoltaic applications continues to increase.

Raw materials revenue increased $3.1 million, or 108.7%, to $5.9 million for the six months ended June 30, 2007 from $2.8 million for the six months ended June 30, 2006. The increase in raw materials revenue was primarily due to sales of gallium to new customers in Japan and Europe as the demand for gallium increases, as well as an increase in raw materials pricing. We expect this demand for gallium to continue at this pace.

Revenue from customers in North America increased by $1.7 million, or 49.6%, to $5.0 million for the three months ended March 31, 2008 from $3.3 million for the three months ended March 31, 2007. We expected our North America revenue to increase substantially in 2008 based upon a supply agreement we signed in the fourth quarter of 2007 with IQE plc. Under the terms of the agreement, IQE plc shall purchase from us a minimum of approximately $15.1 million of 4-inch and 6-inch semi-insulating gallium arsenide (GaAs) substrates. IQE plc has an option to purchase an additional $3.5 million of 6-inch substrates from us under the agreement. All substrates ordered pursuant to the agreement are to be shipped by the end of 2008.

Liquidity and Capital Resources

As of ~~June 30, 2007,~~March 31, 2008, our principal sources of liquidity were ~~$33.7~~$39.4 million in cash and cash equivalents and short-term investments, excluding restricted deposits. We consider cash and cash equivalents and short-term investments as liquid and available for use. Short-term investments are comprised of government bonds and high-grade commercial debt instruments.

Cash and cash equivalents and short-term investments ~~decreased $1.9~~of $39.4 million increased by $0.2 million in the first quarter of 2008 compared to ~~$33.7~~ ~~million as~~the fourth quarter of June 30, 2007 compared with $35.5 million as of December 31, 2006. Included in this decrease are the purchase of machinery and equipment of $2.3 million, payments of long-term debt of $0.4 million, and the continual funding of our operations, partially offset by the net proceeds of $3.7 million received from the public offering of 862,500 shares of our common stock in January 2007.

Net cash used in operating activities of ~~$3.9~~$4.4 million for the ~~six~~three months ended ~~June 30, 2007~~March 31, 2008 was primarily comprised of our net income of ~~$2.6~~$2.0 million, adjusted for non-cash items of depreciation of ~~$0.7~~$0.5 million, ~~stock based~~stock-based compensation of $0.2 million, partially offset by a ~~recovery~~realized gain on sale of ~~impairment on assets held for sale~~investments of $0.5 million, and offset by a net increase of ~~$6.8~~$6.6 million in assets and liabilities. The $6.6 million net increase in assets and liabilities primarily resulted from a ~~$4.6~~$4.4 million increase in accounts receivable, $4.0 million increase in inventories, $1.7 million increase in prepaid expenses, $0.9 million decrease in ~~accounts payable, $0.5~~other long-term liabilities, primarily minority interests, a $0.2 million increase in other assets, ~~and~~ a ~~$0.2~~$0.1 million ~~increase~~decrease in accrued liabilities, partially offset by a $4.5 million decrease in accounts ~~receivable, net, partially offset by~~payable, and a $0.2 million decrease in income taxes payable.

Inventories, net, increased by ~~$4.7~~$4.0 million, ~~or 23.1%, to $24.9 million as of June 30, 2007 compared with $20.3 million as of December 31, 2006,~~ as we increased inventory in raw materials and work-in-process to increase production in anticipation of increased forecast ~~sales. The value of~~sales, and finished goods ~~increased by $0.7 million with respect to~~for consignment ~~inventory as we increased our number of consignees from four to six.~~orders.

Accounts receivable, net increased by ~~$0.2 million, or 2.3%, to $9.9~~$4.4 million, as a result of ~~June 30, 2007 compared to $9.7 million as of December 31, 2006. Gross accounts receivable~~our increased by $0.8 million from $9.8 million to $10.6 million as revenue increased. The allowance for doubtful accounts increased by $0.6 million from $0.1 million to $0.7 million mainly for some slow-paying customers in Asia. We continue to pursue collections on slow-paying customers.sales volume. Our days sales outstanding is 6677 days as of ~~June 30, 2007~~March 31, 2008 compared to 6864 days as of December 31, ~~2006.~~2007.

Net cash ~~used in~~provided by investing activities of ~~$0.3~~$8.7 million for the ~~six~~three months ended ~~June 30, 2007~~March 31, 2008 was primarily from the proceeds from the sale of investments of $10.8 million, proceeds from sale of assets held for sale of $5.1 million and the decrease of restricted cash of $0.2 million, partially offset by the purchase of investments totaling ~~$10.3~~$6.4 million, and the purchase of property, plant and equipment, of ~~$2.3~~$1.0 million, ~~partially offset by the proceeds from sale of investments of $11.9 million and the decrease of restricted cash of $0.3 million.~~

We expect to invest approximately ~~$2.6~~$4.8 million in capital projects for the remainder of ~~2007.~~2008. We believe that our existing and planned facilities and equipment are sufficient to fulfill current and expected future orders.

Net cash provided by financing activities of ~~$3.5~~$0.2 million for the ~~six~~three months ended ~~June 30, 2007~~March 31, 2008 consisted of ~~$3.7~~$0.1 million ~~net~~from the proceeds from the ~~issuance~~exercise of ~~862,500 shares of common stock as a result of our January 2007 closing of our public offer of our common stock and $0.2 million from~~ employee stock options, ~~exercised,~~and $0.3 million from the proceeds of a long term borrowing in one of our joint ventures, partially offset by ~~payments~~a scheduled payment of ~~$0.4~~$0.2 million related to long-term borrowings.

Our main Fremont, California facility is financed by long-term borrowings, which were refinanced by taxable variable rate revenue bonds in 1998. These bonds mature in 2023 and bear interest at a variable rate that was ~~5.42%~~3.25% as of ~~June 30, 2007.~~March 31, 2008. The bonds are traded in the public market. Repayment of principal and interest under the bonds is supported by a letter of credit from our bank and is paid on a quarterly basis. We have the option to redeem the bonds in whole or in part during their term. As of ~~June 30, 2007, $6.9~~March 31, 2008, $6.6 million was outstanding under these bonds.

As of ~~June 30, 2007~~March 31, 2008, the credit facility maintained by us with a bank included a letter of credit supporting repayment of our revenue bonds with an outstanding amount of ~~$6.9~~$6.6 million. We have pledged and placed a like amount of investment securities with an affiliate of the bank as additional collateral for this facility.

~~On June 15, 2007, we entered into a sales agreement with an independent third party to sell~~ We completed the sale of our ~~main~~ Fremont, California ~~facility. We estimate our~~facility on March 28, 2008, and received net proceeds ~~will be~~of approximately $5.1 million after deducting ~~sales commission~~commissions and ~~other~~ selling expenses. We ~~expect~~plan to ~~close escrow in~~repay the ~~third quarter, pending timely sign off~~outstanding principal and accrued interest on the ~~closure report by the local fire department.~~revenue bond of approximately $6.6 million in July 2008, thereby releasing our restricted cash in such amount.

We believe that we have adequate cash and investments to meet our needs over the next 12 months. If our performance fails to improve, we will continue to use cash and may at some time be forced to seek additional capital. There can be no assurance that such additional capital will be available or, if available it will be at terms acceptable to us. Cash from operations could be affected by various risks and uncertainties, including, but not limited to those set forth below under Item 1A “Risks Factors.”

Recent Accounting Pronouncements

In March 2008, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities” (“SFAS 161”). SFAS 161 requires companies with derivative instruments to disclose information that should enable financial-statement users to understand how and why a company uses derivative instruments, how derivative instruments and related hedged items affect a company’s financial position, financial performance and cash flows. SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. Based on our current operations, we do not expect that the adoption of SFAS 161 will have a material impact on our consolidated financial position or results of operations.

beginning after November 15, 2007, and interim periods of those fiscal years. In February 2008, the FASB released a FASB Staff Position (FSP FAS 157-2— Effective Date of FASB Statement No. 157 ) which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually) to fiscal years beginning after November 15, 2008. These non-financial items include assets and liabilities such as reporting units measured at fair value in a goodwill impairment test and non-financial assets acquired and liabilities assumed in a business combination. The partial adoption of SFAS 157 as of January 1, 2008 for financial assets and liabilities did not have a material impact on our condensed consolidated financial position, results of operations or cash flows. See Note 3 of the Notes to Condensed Consolidated Financial Statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency ~~Exchange Rate Exposure~~Risk

~~We operate~~

A significant portion of our business is conducted in currencies other than the U.S. dollar. The functional currency for our foreign operations is the Renminbi, the local currency of China, where our operating expenses are predominantly in the ~~United States, manufacture in the People’s Republic of China (“PRC”), and the substantial majority~~local currency. Since most of our ~~sales to date have been made~~operations are conducted in ~~U.S. dollars. Certain expenses from~~China, most of our ~~PRC operations~~costs are incurred in Chinese currency, which subjects us to fluctuations in the ~~PRC’s Renminbi. As a result, currency fluctuations~~exchange rates between the U.S. dollar and the ~~Renminbi could cause foreign currency~~Chinese Renminbi. We incur transaction gains or losses resulting from consolidation of expenses incurred in local currencies for these subsidiaries, as well as in translation of the assets and liabilities of these assets at each balance sheet date. These risks may be increased by the fluctuations and revaluations of the Chinese Renminbi. Our financial results could be adversely affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets, including the revaluation by China of the Renminbi, and any future adjustments that China may make to its currency such as any move it might make to a managed float systems with opportunistic interventions. In the future we may experience foreign exchange losses on our non-functional currency denominated receivables and payables to the extent that we ~~would recognize~~have not mitigated our exposure utilizing foreign currency forward exchange contracts. Foreign exchange losses could have a materially adverse effect on our operating results and cash flows.

We do not currently use short-term forward exchange contracts for hedging purposes to reduce the effects of adverse foreign exchange rate movements. We had previously purchased foreign exchange contracts to hedge against certain trade accounts receivable denominated in Japanese yen. The change in the ~~period incurred. However, a 10%~~fair value of the forward contracts was recognized as part of the related foreign currency transactions as they occur. As of March 31, 2008, we had no outstanding commitments with respect to foreign exchange contracts.

During the first quarter of 2008, we recorded net realized foreign exchange gains of $189,000, included as part of other expense in our consolidated statements of operations. The foreign exchange gains were primarily due to fluctuation in the ~~dollar at June 30, 2007 would have an immaterial impact on our net dollar position in outstanding trade payables and receivables.~~

~~In July 2005, the PRC uncoupled the~~Chinese Renminbi ~~from~~versus the U.S. ~~dollar and began to permit it to float in a narrow band against a basket of foreign currencies. The move revalued Renminbi by 2.1% against the U.S. dollar; however, it~~dollar. It is uncertain ~~what further adjustments~~whether these currency trends will ~~follow. The Renminbi-U.S. dollar exchange rate could float, and~~continue. In the ~~Renminbi could appreciate relative to the U.S. dollar.~~

~~We expect our international revenues and expenses to continue to be denominated largely in U.S. dollars. We also believe that our PRC operations will likely expand in the~~ future ~~as our business continues to grow. As a result, we anticipate that~~ we may experience ~~increased exposure~~foreign exchange losses on our non-functional currency denominated receivables and payables to the ~~risks~~extent that we have not mitigated our exposure utilizing foreign currency forward exchange contracts. Foreign exchange losses could have a materially adverse effect on our operating results and cash flows. During the first quarter of ~~fluctuating currencies and may choose to engage~~2008, we recorded unrealized foreign currency gains of $1.2 million, in ~~currency hedging activities to reduce these risks. However, we cannot be certain that any such hedging activities will be effective, or available to us at commercially reasonable rates.~~cumulative other comprehensive income on our condensed consolidated balance sheets.

The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. Financial instruments that potentially subject us to concentration of credit risk consist primarily of cash equivalents, short-term investments, and trade accounts receivable. We invest primarily in money market accounts, commercial paper instruments, and investment grade securities. We are exposed to credit risks in the event of default by the issuers to the extent of the amount recorded on the consolidated balance sheets. These securities are generally classified as available-for-sale and consequently are recorded on the balance sheet at fair value with unrealized gains or losses reported as a separate component of accumulated other comprehensive income, net of estimated tax. Our cash, cash equivalents and short-term investments are in high-quality securities placed with major banks and financial institutions and commercial paper. We have no investments in auction rate securities.

Equity Risk

We maintain minority investments in privately-held companies. These investments are reviewed for other than temporary declines in value on a quarterly basis. These investments are classified as other assets in the condensed consolidated balance sheets and are accounted for either under the cost method or under the equity method as we do not have the ability to exercise significant influence over their operations. We monitor our investments for impairment and record reductions in carrying value when events or changes in circumstances indicate that the carrying value may not be recoverable. Reasons for other than temporary declines in value include whether the related company would have insufficient cash flow to operate for the next twelve months, significant changes in the operating performance and changes in market conditions. ~~The~~As of March 31, 2008, the minority investments accounted for under the cost method totaled $0.4 million, ~~as of December 31, 2006 and June 30, 2007.~~while minority investments accounted for under the equity method totaled $3.1 million.

ITEM 4T4. CONTROLS AND PROCEDURES

Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that the our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report.

(b) No change in our internal control over financial reporting was made during the quarter ended ~~June 30, 2007,~~March 31, 2008, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time we may be involved in judicial or administrative proceedings concerning matters arising in the ordinary course of business.
