**VITESSE SEMICONDUCTOR CORPORATION**

**NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS**

 

**March 31, 2011**

 

**Note 1. The Company and Its Significant Accounting Policies**

 

**Description of Business**

 

Vitesse Semiconductor Corporation (“Vitesse,” the “Company,” “us” or “we”) is a leading supplier of high-performance integrated circuits (“ICs”) that are utilized primarily by manufacturers of networking systems for Carrier and Enterprise Networking applications. Vitesse designs, develops and markets a diverse portfolio of high-performance, low-power and cost-competitive semiconductor products. For more than 25 years, Vitesse has been a leader in the transition of new technologies in communications networks.

**Fiscal Year**

 

The Company’s fiscal year is October 1 through September 30.

 

**Basis of Presentation**

 

The interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Securities and Exchange Commission (“SEC”) Form 10-Q and Article 10 of SEC Regulation S-X. They do not include all of the information and footnotes required by generally accepted accounting principles in the United States (“GAAP”) for complete financial statements. Therefore, these financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto for the year ended September 30, 2010, included in our Annual Report on Form 10-K filed with the SEC on December 1, 2010.

 

The consolidated financial statements included herein are unaudited; however, they contain all normal recurring accruals and adjustments that, in the opinion of management, are necessary to present fairly our consolidated financial position at March 31, 2011 and September 30, 2010, the consolidated results of our operations for the three and six months ended March 31, 2011 and 2010 , our consolidated cash flows for the six months ended March 31, 2011 and 2010, and the changes in our stockholders’ deficit for the six months ended March 31, 2011. The results of operations for the three and six months ended March 31, 2011 are not necessarily indicative of the results to be expected for future quarters or the full year.

 

**Reclassifications**

 

Certain reclassifications have been made to prior year amounts and related footnotes to conform to current-year presentation.

 

**Use of Estimates**

 

The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and disclosures made in the accompanying notes to the unaudited consolidated financial statements. The Company regularly evaluates estimates and assumptions related to revenue recognition, allowances for doubtful accounts, warranty reserves, inventory reserves, share-based compensation, derivative valuation, purchased intangible asset valuations and useful lives, and deferred income tax asset valuation allowances. These estimates and assumptions are based on current facts, historical experience and various other factors that the Company believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. The actual results the Company experiences may differ materially and adversely from its original estimates. To the extent there are material differences between the estimates and the actual results, the Company’s future results of operations will be affected.

**Financial Instruments**

 

ASC Topic 825, “Financial Instruments,” defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties. The Company’s financial instruments include cash equivalents, restricted cash, accounts receivable, accounts payable, accrued expenses and various debt instruments. These financial instruments are stated at their carrying values, which are estimates of their fair values because of their nearness to cash settlement or the comparability of their terms to the terms the Company could obtain, for similar instruments, in the current market.

 

Restricted cash consists of various commitments of $0.4 million recorded in other current assets, as well as interest-bearing certificates of deposit (“CDs”) collateralizing letters of credit of $1.5 million, which are included in other assets in the Unaudited Consolidated Balance Sheets as of March 31, 2011.

 

Effective February 4, 2011, the Company exchanged the existing Senior Term Loan into two term loans (the Term Loans A and B), each in the principal amount of $9.34 million.

 

Pursuant to ASC 470, the Company recorded the new Term Loans A and B, (see discussion in Note 3 Debt in the accompanying  Notes to Unaudited Financial Statements.), issued in extinguishment of the Senior Term Loan at fair value and recognized a  $3.9 million loss for the difference between the aggregate fair values of the new instruments plus additional amounts and fees paid to the noteholders compared to the net carrying value of the Senior Term Loan. For the purposes of calculating this loss on  extinguishment, the net carrying amount of the Senior Term Loan was $18.7 million, which included the remaining outstanding  principal of $17.0 million, the Payment-in-Kind (“PIK”) balance of $1.7 million, and the balance of the unamortized costs of $0.6 million, as of February 4, 2011.

 

The Company estimates the fair values of the Term Loans A and B using a convertible bond valuation model within a lattice  framework. These valuations are determined using Level 3 inputs. The valuation model combines expected cash outflows with  market-based assumptions regarding risk-adjusted yields, stock price volatility, recent price quotes and trading information of the  Company’s common stock into which the Term B loan is convertible. As of March 31, 2011, the fair value and the carrying value of the Term A Loan was $9.9 million, including an unamortized premium of $0.5 million. The fair value of the Term B Loan was $11.9 million.

 

The Company estimates the fair values of the 2014 Debentures and embedded derivatives using a convertible bond valuation model within a lattice framework. These valuations are determined using Level 3 inputs. The valuation model combines expected cash outflows with market-based assumptions regarding risk-adjusted yields, stock price volatility, recent price quotes and trading information of the Company’s common stock into which the 2014 Debentures are convertible. As of March 31, 2011, the fair value of the 2014 Debentures is $44.5 million excluding the fair value of the compound embedded derivative of $20.9 million. The change in fair value from September 30, 2010 is reflected as a loss on embedded derivative in the Unaudited Consolidated Statement of Operations for the three and six months ended March 31, 2011. As of March 31, 2011, the outstanding 2014 Debentures were carried on the balance sheet at $39.9 million, net of a $6.6 million remaining discount, which is amortized as interest expense over the life of the debentures.

 

The Company marks the compound embedded derivative to market due to the conversion price not being indexed to the Company’s own stock. Specifically, the debt feature requiring the Company to redeem foregone interest upon conversion by the holder causes the exercise price not to be indexed to the Company’s own stock. The change in the fair value of the compound embedded derivative is primarily related to the change in price of the underlying common stock. The change in value of the compound embedded derivative is a non-cash item. At the Company’s option, it can settle the embedded derivative in either cash or common shares. As the Company intends to, and has the ability to, satisfy the obligations with equity securities, in accordance with ASC Topic 470 Debt (“ASC 470”), the Company has classified the liability as a long-term liability on its Unaudited Consolidated Balance Sheet as of March 31, 2011.

**Recent Accounting Pronouncements**

 

In October 2009, the FASB issued ASU No. 2009-13,*Revenue Recognition (ASC Topic 605) — Multiple-Deliverable Revenue Arrangements*, a consensus of the FASB Emerging Issues Task Force.  This guidance modifies the fair value requirements of ASC subtopic 605-25,*  Revenue Recognition-Multiple Element Arrangements* by allowing the use of the best estimate of selling price in addition to vendor-specific objective evidence and verifiable objective evidence (now referred to as third-party evidence) for determining the selling price of a deliverable. A vendor is now required to use its best estimate of the selling price when vendor-specific objective evidence or third-party evidence of the selling price cannot be determined. In addition, the residual method of allocating arrangement consideration is no longer permitted.  ASU 2009-13 is effective for fiscal years beginning on or after June 15, 2010. The Company has adopted the provisions of ASU 2009-13 and the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

 

In October 2009, the FASB issued ASU No. 2009-14,*Software (ASC Topic 985) — Certain Revenue Arrangements That Include Software Elements*, a consensus of the FASB Emerging Issues Task Force.  This guidance modifies the scope of ASC subtopic 985-605,*Software-Revenue Recognition* to exclude from its requirements (a) non-software components of tangible products and (b) software components of tangible products that are sold, licensed, or leased with tangible products when the software components and non-software components of the tangible product function together to deliver the tangible product’s essential functionality.  ASU 2009-14 is effective for fiscal years beginning on or after June 15, 2010. The Company has adopted the provisions of ASU 2009-14 and the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

In accordance with ASC Topic 260 Earnings per Share (“ASC 260”), basic net income and loss per share is computed by dividing net income or loss by the weighted average number of common shares outstanding during the period.

 

For the three and six months ended March 31, 2011 and 2010, the Company recorded a net loss and in accordance with ASC 260, all outstanding potential common shares were excluded from the diluted loss per share computation. For periods in which the Company reports a net loss, diluted loss per share is calculated using only the weighted average number of shares outstanding during each of the periods, as the inclusion of any common stock equivalents would be anti-dilutive.

 

Under the two-class method of determining earnings for each class of stock, the Company considers the dividend rights and participation rights in undistributed earnings for each class. For the three and six months ended March 31, 2011 and 2010 , the dividend rights on the outstanding preferred shares are not material to the calculation, and therefore, not considered in determining earnings and losses per preferred share. The allocation of undistributed earnings to preferred shares is equal to the amount of earnings per common share that would be distributed on an as-converted basis.

 

The potential common shares excluded from the diluted loss per share computation are as follows:

**Note 3. Debt**

 

As of March 31, 2011, the outstanding 2014 Debentures were carried on the balance sheet at $39.9 million, net of a $6.6 million remaining discount. Unamortized debt issuance costs, as of March 31, 2011, were $0.9 million. The 2014 Debentures mature in October 2014 and bear interest at a fixed rate of 8.0% per annum. Interest is payable semi-annually.

 

On January 18, 2011, the Company paid $8.0 million against the principal balance of the Senior Term Loan. Effective February 4, 2011, the Company exchanged the existing Senior Term Loan into two term loans (the Term Loans A and B), each in the principal amount of $9.34 million.

 

The Term A Loan bears interest at a fixed rate of 10.5% per annum beginning on February 4, 2011, payable quarterly in arrears, with a maturity date of February 4, 2014. Prepayment of the Term A Loan is permitted at 101% of the principal amount plus accrued interest until August 4, 2011, after which the prepayment option expires.

 

The Term B Loan bears interest at a fixed rate of 8.0% per annum beginning on February 4, 2011, payable quarterly in arrears, with a maturity date of October 30, 2014, unless earlier converted. Prepayment of the Term B Loan is not permitted prior to October 30, 2011. On or after October 30, 2011, prepayments on the Term B Loan are permitted at 100% of the principal amount plus accrued interest, but only if the closing sale price of the common stock has been at least 130% of the conversion price in effect for at least 20 trading days during any 30 consecutive trading day period ending on the day prior to the date of notice of prepayment.

 

The Term B Loan is convertible into shares of common stock at a conversion price of $4.95 per share (equivalent to an initial conversion rate of approximately 202 shares per $1,000 principal amount of the Term B Loan). The terms of conversion for the Term B Loan are substantially similar to the conversion terms for the Company’s 2014 Debentures except that there is no make-whole interest amount payable upon conversion. Full conversion of the $9.34 million in aggregate principal amount of the Term B Loan would result in the issuance of 1,887,234 shares of common stock, as of February 4, 2011.

 

The Company evaluated the Term A and B Loans issued in exchange for the Senior Term Loan pursuant to the guidance in ASC 470. The Company determined that it has not received any concessions from the noteholders in connection with the Second Amendment to Loan Agreement and accordingly the transaction will not be accounted for as a troubled debt restructuring. However, due to the addition of a substantive conversion feature of the new instrument issued, as compared to the terms of Senior Term Loan, the Company accounted for the exchange of instruments, in settlement for the Senior Term Loan, as a debt extinguishment, pursuant to the guidance in ASC 470.

 

Pursuant to ASC 470, the Company recorded the new Term Loans A and B, issued in extinguishment of the Senior Term Loan at fair value and recognized a $3.9 million loss for the difference between the aggregate fair values of the new instruments plus additional amounts and fees paid to the noteholders compared to the net carrying value of the Senior Term Loan. For the purposes of calculating this loss on extinguishment, the net carrying amount of the Senior Term Loan was $18.7 million, which included the remaining outstanding principal of $17.0 million, the Payment-in-Kind (“PIK”) balance of $1.7 million, and the balance of the unamortized costs of $0.6 million, as of February 4, 2011.

 

On February 4, 2011, the Company recorded the Term A Loan at fair value, which was $9.9 million, including a premium of $0.6 million, The difference between the fair value and the face value (principal) of the Term A Loan represents a premium that will be amortized as a reduction of interest expense over the life of the loan.  The premium calculated for the Term A Loan decreased the Company’s effective interest rate of interest from the stated fixed rate of 10.5% per annum. At March 31, 2011, the effective interest rate on the Term A Loan was 8.5%. The carrying value will decrease over the life of the Term A Loan as the excess of the fair value over the face value of the note is amortized. As of March 31, 2011, the Term A Loan was carried on the balance sheet at $9.9 million, including the unamortized premium of $0.5 million. For the three and six months ended March 31, 2011, interest expense related to the Term A Loan premium was $0.03 million.  

 

On February 4, 2011, the Term B Loan fair value was determined to be $11.9 million, which included a premium of $2.6 million representing the difference between the fair value of the loan, including all terms and features of the note, and the face value of the note of $9.3 million.  Since the note included an equity conversion feature, the $2.6 million premium was credited to additional paid in capital in accordance with ASC 470-20-25.  Additionally, as the equity conversion feature allows for the Company to potentially settle any conversion request in either shares of its common stock or cash, at the Company’s option, it was allocated a value of $2.5 million calculated as the difference between the $9.3 million face value of the note and the $6.9 million estimated fair value of the note, as determined based upon the note as  an assumed standalone instrument including all terms and features except the equity conversion feature.  The allocated equity conversion feature value of $2.5 million was recorded as a debt discount and a credit to additional paid in capital in accordance with ASC 470-20-15.  The debt discount will be amortized as additional interest expense over the life of the debt using the effective interest method.  Accordingly, the Term B loan debt discount increased the Company’s effective rate of interest from the stated or nominal fixed rate of 8.0% per annum to an effective interest rate of 17.7% per annum as of March 31, 2011.  As of March 31, 2011, the Term B Loan was carried on the balance sheet at $6.9 million, net of the unamortized discount of $2.4 million. For the three and six months ended March 31, 2011, net interest expense related to the Term B Loan discount was $0.1 million.

The compound embedded derivative liability, which is included in long term liabilities, represents the value of the equity conversion feature and a “make-whole” feature of the 2014 Debentures. The make-whole feature, requiring the Company to redeem foregone interest upon conversion by the holder, which for accounting purposes results in the exercise price not being indexed to the Company’s own stock, which in turn results in the presentation of the compound embedded derivative as a standalone liability at fair value.

 

There is no current observable market for this type of derivative and, as such, the Company determined the value of the embedded derivative using a lattice-based convertible bond valuation model that combined expected cash outflows with market-based assumptions. The fair value of the 2014 Debentures without the embedded compound derivative feature was also estimated using a convertible bond valuation model within a lattice framework. The convertible bond valuation model combined expected cash outflows with market-based assumptions regarding risk-adjusted yields, stock price volatility and recent price quotes and trading information regarding shares of the Company’s common stock into which the 2014 Debentures are convertible. The Company will mark the embedded derivative to market due to the conversion price not being indexed to the Company’s own stock. The change in the fair value of the bifurcated compound embedded derivative is primarily related to the change in price of the underlying common stock.

 

The valuation methodologies used by the Company as described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although management believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

**Note 5. Income Taxes**

 

The provision for income taxes as a percentage of income from operations before income taxes was (0.75%) for the six months ended March 31, 2011 compared to (9.73%) for the comparable period in the prior year. For the year ending September 30, 2011, the Company’s estimated effective tax rate is (1.51%).  The Company’s effective tax rate is primarily impacted by operating losses.

 

Because the Company has historically experienced net tax losses, the Company has placed a valuation allowance against its otherwise recognizable deferred tax assets.

 

The total amount of gross unrecognized tax benefits was approximately $10.7 million as of March 31, 2011 and approximately $10.6 million as of September 30, 2010. The total amount of gross unrecognized tax benefits increased by $0.1 million related to potential state tax liabilities.

 

As of March 31, 2011, approximately $0.8 million of the $10.7 million FIN 48 unrecognized tax benefits, related to the Company’s state tax liability, is recorded in accrued expenses and other current liabilities on the Unaudited Consolidated Balance Sheet. The remaining $9.9 million, related to state research and development tax credits that have not been utilized, is reflected as a reduction to the deferred tax asset arising from the state research and development tax credits.

 

As of September 30, 2010, approximately $0.7 million of the $10.6 million FIN 48 unrecognized tax benefits, related to the Company’s state tax liability, is recorded in accrued expenses and other current liabilities on the Unaudited Consolidated Balance Sheet. The remaining $9.9 million, related to state research and development tax credits that have not been utilized, is reflected as a reduction to the deferred tax asset arising from the state research and development tax credits.

**Note 7. Commitments and Contingencies**

 

From time to time in our normal course of business we are a party to various legal claims, actions and complaints.  Although the ultimate outcome of these matters cannot be determined, management believes that, as of March 31, 2011, the final disposition of these proceedings will not have a material adverse effect on the financial position, results of operations, or liquidity of the Company.

 

***The DOJ Subpoena and SEC Investigation***

 

On March 22, 2011, the United States District Court for the Southern District of New York approved the Company’s settlement with the SEC related to the SEC’s investigation of the Company’s historical stock option practices and accounting irregularities that occurred between 1995 and 2006 (“Consent Judgment”). Under the Consent Judgment, the Company paid a $3.0 million civil penalty and consented to the entry of a final judgment permanently enjoining the Company from violations of the antifraud and other provisions of the federal securities laws. The $3.0 million payment was accrued in the Company’s financial statements in June 2009.

**Overview**

 

Over the last 10 years, the worldwide proliferation of the Internet and the rapid growth in the volume of data being sent over LANs and WANs has placed a tremendous strain on the existing communications infrastructure. Communication service providers have sought to increase their revenues by delivering a growing range of data services to their customers in a cost-effective manner. The resulting demand for increased bandwidth and services has created a need for faster, larger and more complex networks.

 

The Company is a leading supplier of high-performance integrated circuits (“ICs”) principally targeted at systems manufacturers in the communications industry. Within the communications industry, the Company’s products address Carrier and Enterprise Networking, where they enable data to be transmitted at high-speeds and processed and switched under a variety of protocols.

 

In recent years, the Company has focused its product development and marketing efforts on products that leverage the convergence of Carrier and Enterprise Networking onto Internet Protocol based networks. These “Next-Generation Networks” share the requirements of high reliability, scalability, interoperability and low cost. Increasingly, these networks will be delivered based on Ethernet technology. The Company believes that products in this emerging technology area represent the best opportunity for the Company to provide differentiation in the market.

 

**Debt Restructuring**

 

The Company exchanged the Senior Term Loan Agreement effective February 4, 2011, to convert the existing Senior Term Loan into two term loans, each in the principal amount of $9.34 million.

 

The Term A Loan bears interest at a fixed rate of 10.5% per annum beginning on February 4, 2011, payable quarterly in arrears, with a maturity date of February 4, 2014. Prepayment of the Term A Loan is permitted at 101% of the principal amount plus accrued interest until August 4, 2011 after which the prepayment option expires.

 

The Term B Loan bears interest at a fixed rate of 8.0% per annum beginning on February 4, 2011, payable quarterly in arrears, with a maturity date of October 30, 2014, unless earlier converted. Prepayment of the Term B Loan is not permitted prior to October 30, 2011. On or after October 30, 2011, prepayments on the Term B Loan are permitted at 100% of the principal amount plus accrued interest, but only if the closing sale price of the common stock has been at least 130% of the conversion price in effect for at least 20 trading days during any 30 consecutive trading day period ending on the day prior to the date of notice of prepayment.

 

The Term B Loan is convertible into shares of common stock at a conversion price of $4.95 per share (equivalent to an initial conversion rate of approximately 202 shares per $1,000 principal amount of the Term B Loan). The terms of conversion for the Term B Loan are substantially similar to the conversion terms for the Company’s 2014 Debentures except that there is no make-whole

interest amount payable upon conversion. Full conversion of the $9.34 million in aggregate principal amount of the Term B Loan would result in the issuance of 1,887,234 shares of common stock as of February 4, 2011.

 

On February 4, 2011, the Term B Loan fair value was determined to be $11.9 million, which included a premium of $2.6 million representing the difference between the fair value of the loan, including all terms and features of the note, and the face value of the note of $9.3 million.  Since the note included an equity conversion feature, the $2.6 million premium was credited to additional paid in capital in accordance with ASC 470-20-25.  Additionally, as the equity conversion feature allows for the Company to potentially settle any conversion request in either shares of its common stock or cash, at the Company’s option, it was allocated a value of $2.5 million calculated as the difference between the $9.3 million face value of the note and the $6.9 million estimated fair value of the note, as determined based upon the note as  an assumed standalone instrument including all terms and features except the equity conversion feature.  The allocated equity conversion feature value of $2.5 million was recorded as a debt discount and a credit to additional paid in capital in accordance with ASC 470-20-15.  The debt discount will be amortized as additional interest expense over the life of the debt using the effective interest method.  Accordingly, the Term B loan debt discount increased the Company’s effective rate of interest from the stated or nominal fixed rate of 8.0% per annum to an effective interest rate of 17.7% per annum as of March 31, 2011.  As of March 31, 2011, the Term B Loan was carried on the balance sheet at $6.9 million, net of the unamortized discount of $2.4 million. For the three and six months ended March 31, 2011, net interest expense related to the Term B Loan discount was $0.1 million.

 

Pursuant to ASC 470, the Company recorded the new Term Loans A and B, (see discussion in Note 3 Debt in the accompanying Notes to Unaudited Financial Statements.), issued in extinguishment of the Senior Term Loan at fair value and recognized a $3.9 million loss for the difference between the aggregate fair values of the new instruments plus additional amounts and fees paid to the noteholders compared to the net carrying value of the Senior Term Loan. For the purposes of calculating this loss on extinguishment, the net carrying amount of the Senior Term Loan was $18.7 million, which included the remaining outstanding principal of $17.0 million, the Payment-in-Kind (“PIK”) balance of $1.7 million, and the balance of the unamortized costs of $0.6 million, as of February 4, 2011.

 

**Critical Accounting Policies and Estimates**

 

Our critical accounting policies and estimates are described in our Annual Report on Form 10-K for the year ended September 30, 2010. There have been no significant changes to these policies during the six months ended March 31, 2011. These policies and estimates continue to be those that we believe are most important to a reader’s ability to understand our financial results.

***Product Revenues***

 

The Company classifies its IC products into three categories: (i) Carrier Networking Products; (ii) Enterprise Networking Products; and (iii) Non-Core Products. The Carrier Networking Products service core, metro and access networks. The Enterprise Networking Products service the market for Ethernet switching and transmission within local area networks in small-medium enterprise (“SME”) and small-medium business (“SMB”) markets. Non-Core Products have not received additional investment over the last five years and, as a result, have generally been in decline.

 

The following tables summarize the Company’s product revenues by product line:

Net product revenues for the three and six months ended March 31, 2011 were $34.4 million and $72.0 million, respectively, compared to $43.7 million and $85.3 million for the same periods in 2010.

 

Net product revenues from Carrier Networking for the three and six months ended March 31, 2011 decreased by $1.7 million and $2.7 million, respectively, compared to the same periods in 2010, primarily due to continued weakness in the Asia Pacific region, which declined by $1.5 million from the same period in 2010 and $4.3 million compared to the first six months in 2010. The weakness was seen across a wide range of customers and products, primarily in China.  Compared with the second quarter of fiscal year 2010, we saw growth in some of our connectivity products, including our crosspoint switch and 1Gigabit Ethernet PHY products offset by declines in our legacy processing products for SONET applications.

 

Net product revenues from Enterprise Networking for the three and six months ended March 31, 2011 decreased by $3.3 million and $4.0 million, respectively, compared to the same periods in 2010. The decrease is primarily due to weakness in the Company’s switch and 1Gigabit Ethernet PHY products selling into low-end SME applications.

 

Net product revenues from Non-Core for the three and six months ended March 31, 2011 decreased by $4.3 million and $6.5 million, respectively, compared to the same periods in 2010. The decrease is primarily due to a decline of the Company’s Network Processing Product line and legacy Fibre Channel PHY products.

The increase in IP revenues is from two agreements completed during the quarter.  The Company recognized royalty revenues of $0.1 million and $0.3 million for the three and six months ended March 31, 2011, respectively. No material royalties were received or recognized for the same periods in 2010.

As a fabless semiconductor Company, we use third-parties for wafer fabrication and assembly services.  Cost of revenues consists predominantly of: (i) purchased finished wafers; (ii) assembly services; (iii) test services; and (iv) labor and overhead costs associated with product procurement, planning, and quality assurance. There was no cost of revenues associated with IP revenues for any periods presented in this report.

 

Cost of net revenues for the three and six months ended March 31, 2011 decreased by $6.4 million and $11.1 million, respectively, compared to the same periods in 2010. As a percentage of net revenues, the cost of net revenues for the three and six months ended March 31, 2011 were 35.2% and 36.6%, respectively, compared 44.1% and 45.0% for the same periods in 2010.

 

Excluding IP revenue, the cost of net product revenues for the three and six months ended March 31, 2011 was 37.8% and 38.0%, respectively, compared to 44.3% and 45.1% for the same periods in 2010.

 

The decrease in the cost of net product revenues is primarily attributable to improved material costs, improved product yields and the transition of the Company’s test manufacturing activities from its California facility to an outsource model using an offshore facility. This transition resulted in reduced costs of tests. In addition to these material cost savings, the Company has increased the percentage of its switching products sold into the Carrier market segment relative to the Enterprise market segment. These products tend to carry higher overall average selling prices in the Carrier market segment.

 

For the three and six months ended March 31, 2011, the Company decreased production volumes in response to market declines and substantial improvements in availability of capacity at foundries and assembly sub-contractors which obviates the need for higher inventory balances.  The lower production volumes

experienced in the three and six months ended March 31, 2011, as the Company took actions to reduce inventory levels, increased current inventory unit costs.  As we reduce our inventory levels consistent with our long term goal of five inventory turns, we anticipate that the sale of these inventories will temporarily increase our cost of net product revenues in future periods and simultaneously reduce our reported product margins.

 

The Company continued to focus its efforts on improving operating efficiencies, including improving product yields, reducing scrap, and improving cycle times.

Engineering, research and development expenses consist primarily of salaries and related costs, including share-based compensation expense of employees engaged in research, design and development activities. Engineering, research and development also includes costs of mask sets and electronic design automation tools, software licensing contracts, subcontracting and fabrication costs, depreciation and amortization, and facilities expenses. The Company will continue to concentrate its spending in this area to meet its customer requirements and to respond to market conditions.

 

Engineering, research and development expense increased $2.7 million and $5.2 million for the three and six months ended March 31, 2011, respectively, compared to the same periods in 2010. As a percentage of net revenues, engineering, research and development expenses for the three and six months ended March 31, 2011 increased to 40.6% and 39.4%, respectively, compared to 28.0% and 28.3% for the same periods in 2010.

 

The increase in engineering, research and development expenses for the three and six months ended March 31, 2011 is mainly attributable to increased engineering tool costs of $1.9 million and $3.7 million, respectively. The engineering tool costs are comprised of mask sets, electronic design automation tools, and new product evaluation boards associated with a higher level of new product introductions in the periods.

 

The Company had a $0.1 million increase in non-cash stock compensation expense for the three and six months ended March 31, 2011, respectively, as well as a $0.1 million and $0.3 million increase in severance costs for the three and six months ended March 31, 2011, respectively. The Company anticipates a total of $0.5 million in severance costs to be recognized over the first three quarters of 2011, of which $0.3 million occurred in the first six months of 2011, related to headcount reduction taken over the period. The reduction in headcount will decrease spending on research and development by approximately $2 million annually by the end of 2011 and will not impact product development in 2011.

 

The Company continues to concentrate its investments in areas that match its customers’ requirements and market conditions.

Selling, general and administrative ("SG&A") expense consists primarily of legal and other professional fees, facilities expenses, and outside labor, as well as personnel-related expenses, including share based compensation expense.

 

SG&A expenses increased $0.9 million and $0.8 million for the three and six months ended March 31, 2011, respectively, compared to the same periods of 2010.

 

The increase in SG&A expense for the three and six months ended March 31, 2011 is due in part to an increase in compensation and benefits costs of approximately $0.6 million and $1.6 million, respectively, of which approximately $0.3 million and $0.4 million, respectively, are attributable to increases in non-cash stock compensation. In addition, facility and administrative costs increased $0.6 million and $1.1 million, respectively, primarily due to re-allocation of our facility in Camarillo, California from cost of revenues to SG&A due to closure of our test floor and the move to an outsource model. The increase in SG&A expenses for the three and six months ended March 31, 2011 was partially offset by a decrease in legal and accounting fees of $0.4 million and $1.1 million, respectively and a $1.0 million non-recurring debt restructuring charge related to the debt restructuring in October 2009.

Net interest expense is comprised of interest expense, net of interest income, and amortization of debt discount and premium, and amortization of debt issuance costs.

 

For the three and six months ended March 31, 2011, interest expense decreased by $0.5 million and $1.1 million, respectively, compared to the same periods in 2010. The decrease is primarily due to the pay-down of $8.0 million on the Senior Term Loan in January 2011 and restructuring of the Senior Term Loan on February 4, 2011.  (See Note 3 Debt in the accompanying Notes to Unaudited Consolidated Financial Statements.)

For the three and six months ended March 31, 2011, the loss on embedded derivative decreased by $28.4 million and $32.1 million, respectively compared to the same periods in 2010. The change in the fair value of the embedded derivatives is primarily related to the change in price of the underlying common stock. The loss on the embedded derivative associated with the 2014 Debentures was $2.0 million and $5.5 million for the three and six months ended March 31, 2011, respectively, compared to $30.4 million and $36.4 million for the same periods in 2010.  The Company also recorded a loss of $1.1 million, for the six months ended March 31, 2010, to reflect the fair value of the derivative liability—premium put associated with the Company’s then outstanding 2024 Debentures at the date the put option was exercised.

In fiscal year 2011, the loss on extinguishment of debt was $3.9 million.   The loss on extinguishment of debt in fiscal year 2011 is associated with the restructuring of the Senior Term Loan on February 4, 2011 (See Note 3 Debt in the accompanying Notes to Unaudited Consolidated Financial Statements.)

 

In fiscal year 2010, the Company finalized negotiations with the noteholders of the 2024 Debentures to settle the obligation, including all amounts owed under the derivative liability for the premium put option, with a combination of cash; shares of the Company’s common stock, shares of the Company’s Series B Preferred stock, and $50.0 million face value of 2014 Debentures. The Company recorded the new instruments issued in extinguishment of the 2024 Debentures at fair value and recognized a $21.6 million loss for the difference between the fair values of the new instruments and includes approximately $0.8 million for fees paid to the noteholders, compared to the net carrying value of the 2024 Debentures. For the purposes of calculating this loss on extinguishment, the net carrying amount of the 2024 Debentures includes the $96.7 million of the 2024 Debentures and $13.3 million of the premium put derivative, recorded at fair value as required by ASC 470.

*Net Cash Used in Operating Activities*

 

During the six months ended March 31, 2011, the Company’s operating activities used $8.7 million in cash.  The Company’s net loss of $16.8 million included non-cash charges of $5.5 million on the change in fair value of the embedded derivative liability for the 2014 Debentures, $3.9 million on the loss on extinguishment of debt, $1.9 million of depreciation and amortization expense, $1.6 million of share-based compensation expense, $0.4 million in capitalized interest related to long-term debt, and $0.9 million of amortization of debt discounts.

 

Accounts receivable decreased by $0.4 million to $15.4 million at March 31, 2011 from $15.8 million at September 30, 2010. The decrease is primarily due to the timing of sales and a decrease in revenues compared to the same period last year. Inventory decreased by $1.4 million to $25.9 million at March 31, 2011 from $27.3 million at September 30, 2010. The Company decreased purchasing in the first and second quarters of fiscal year 2011 as compared to the same periods in 2010.

 

Accounts payable decreased by $2.1 million to $11.1 million at March 31, 2011 from $13.2 million at September 30, 2010. Accounts payable decreased primarily due to a reduction in purchases from our suppliers once industry-wide material shortages eased, as well as the timing of payments to our vendors and other service providers. Accrued expenses and other liabilities decreased by $3.3 million to $13.0 million at March 31, 2011 from $16.3 million at September 30, 2010. Accrued expenses and other liabilities decreased primarily due to the payment of the $3.0 million SEC settlement and the timing of payments to our vendors and other service providers.

 

*Net Cash Used in Investing Activities*

 

Investing activities used $2.5 million in cash in the six months ended March 31, 2011, primarily for capital expenditures. Investing activities used $1.2 million in cash in the six months ended March 31, 2010, primarily for capital expenditures.

 

*Net Cash Used in Financing Activities*

 

Financing activities used $8.7 million in cash in the six months ended March 31, 2011, primarily for a principal payment of $8.0 million on the Senior Term loan, and $0.6 million for the repurchase and retirement of restricted stock units for payroll taxes. In the six months ended March 31, 2010, financing activities used $17.6 million, primarily due to a cash payment of $10.0 million to the holders of 2024 Debentures, $5.0 million to pay down the principal amount of the Senior Term Loan, equity issuance costs of $1.1 million, and debt issuance costs of $1.4 million.

**ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

 

Our quantitative and qualitative disclosures about market risk are described in our Annual Report on Form 10-K for the year ended September 30, 2010. There have been no material changes to these risks during the six months ended March 31, 2011.

 

**ITEM 4. CONTROLS AND PROCEDURES**

 

**Evaluation of Disclosure Controls and Procedures**

 

Under the supervision and with the participation of the Company’s management, including its Chief Executive Officer and Chief Financial Officer, the Company has evaluated the effectiveness of the design and operation of its disclosure controls and procedures, as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act. Disclosure controls and procedures are designed to ensure that information required to be disclosed by the Company in the reports the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within required time periods, and is accumulated and communicated to the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of March 31, 2011, these disclosure controls and procedures were effective.

 

**Changes in Internal Control Over Financial Reporting**

 

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the three months ended March 31, 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

 

**Inherent Limitation on the Effectiveness of Internal Controls**

 

The effectiveness of any system of internal control over financial reporting is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting can only provide reasonable, not absolute, assurances. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. The Company intends to continue to monitor and upgrade its internal controls as necessary or appropriate for the business, but cannot assure you that such improvements will be sufficient to provide effective internal control over financial reporting.
