Disclosure Text Block [Abstract]
Basis of Accounting [Text Block]	(1)  BASIS OF PRESENTATION
	The condensed consolidated financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The information furnished in the condensed consolidated financial statements includes normal recurring adjustments and reflects all adjustments which are, in the opinion of our management, necessary for a fair presentation of such financial statements. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. Although we believe that the disclosures are adequate to make the information presented not misleading, we suggest that these condensed consolidated financial statements be read in conjunction with the financial statements and the notes thereto included in our latest Annual Report on Form 10-K. The quarterly results are not necessarily indicative of the actual results that may occur for the entire fiscal year.

Receivables [Abstract]
Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	(4)  TRADE RECEIVABLES
	Early in the second quarter of 2015, we received a $15,000,000 advance payment from a customer for suspension assemblies, a portion of which were shipped to that customer and recognized as revenue during our second quarter of 2015 and the remainder are expected to ship to that customer during our third quarter of 2015. As of March 29, 2015, $5,985,000 of the advance payment remained outstanding and was included in the line item “Accrued expenses” on our condensed consolidated balance sheets. The prepayment also reduced the open trade receivable balance for that customer.
	We grant credit to our customers, but generally do not require collateral or any other security to support amounts due. Trade receivables of $15,781,000 at March 29, 2015, and $23,971,000 at September 28, 2014, are net of allowances for sales returns of $492,000 and $497,000, respectively.
	During the twenty-six weeks ended March 29, 2015, we entered into multiple independent bill of exchange discounting transactions under an uncommitted facility with Hongkong and Shanghai Banking Corporation Limited, Bangkok Branch (“HSBC”), under which our Thai subsidiary, Hutchinson Technology Operations (Thailand) Co. Ltd., sold, without recourse, an aggregate of $29,284,000 of its accounts receivable to HSBC and was paid 95% of the face value of the accounts receivable, less interest expense of LIBOR plus 1.75%. Upon full payment of the accounts receivable by its customer to HSBC, our Thai subsidiary receives from HSBC the 5% remainder due on the receivable. As of March 29, 2015, there remained $944,000 to be paid to our Thai subsidiary from HSBC, all of which was included within the line item “Other receivables” on our condensed consolidated balance sheets.
	We generally warrant that the products sold by us will be free from defects in materials and workmanship for a period of one year or less following delivery to our customer. Upon determination that the products sold are defective, we typically accept the return of such products and refund the purchase price to our customer. We record a provision against revenue for estimated returns on sales of our products in the same period that the related revenues are recognized. We base the allowance on historical product returns, as well as existing product return authorizations. The following table reconciles the changes in our allowance for sales returns under warranties:

	October 2014 Financing Transactions
	On October 23, 2014, we issued $37,500,000 aggregate principal amount of 8.50% Convertible Senior Notes due 2019 (the “8.50% New Convertible Notes”). The 8.50% New Convertible Notes bear interest at a rate of 8.50% per annum, payable semi-annually in arrears on April 30 and October 31 of each year, beginning April 30, 2015. The 8.50% New Convertible Notes mature on October 31, 2019. Each $1,000 principal amount of the 8.50% New Convertible Notes is convertible into 266.6667 shares of our common stock (which is equal to an initial conversion price of approximately $3.75 per share), subject to adjustment under certain circumstances. The 8.50% New Convertible Notes rank pari passu in right of payment with all existing and future senior indebtedness of our company. Certain beneficial holders of the 8.50% New Convertible Notes had the right to require us to repurchase for cash up to $7,500,000 aggregate principal amount of the 8.50% New Convertible Notes, plus accrued and unpaid interest, if any, during the 120-day period commencing on October 23, 2014. Accordingly, $7,500,000 of the proceeds to us from the sale of the 8.50% New Convertible Notes was escrowed until the put right expired on February 20, 2015. Additionally, we were required to escrow at least $35,000,000 of cash that was restricted solely for the repayment, repurchase, redemption, defeasance or other acquisition for value of our 8.50% Convertible Senior Notes due 2026 (the “8.50% Convertible Notes”), plus accrued but unpaid interest thereon. We capitalized debt financing costs of $1,652,000 which are being amortized over five years or until the maturity date. The amortization expense is included in interest expense. On January 15, 2015, we completed a redemption of the existing $39,822,000 aggregate principal amount of 8.50% Convertible Notes. To fund this, we used the escrowed $35,000,000 and our existing cash.
	On October 23, 2014, we entered into an agreement providing for the private exchange of $15,000,000 aggregate principal amount of our 8.50% Senior Secured Second Lien Notes due 2017 (the “8.50% Secured Notes”) held by a certain holder for 2,500,000 shares of our common stock and warrants to purchase an additional 2,500,000 shares of our common stock on a cashless basis at an exercise price of $0.01 per share. On November 25, 2014, 1,250,000 warrants were exercised which resulted in the issuance of 1,246,493 shares of common stock. On January 15, 2015, the remaining 1,250,000 warrants were exercised, which resulted in the issuance of 1,246,428 shares of common stock and no warrants remain outstanding. The fair value of the common stock and warrants was recorded in additional paid-in capital in the amount of $17,388,000. Applying debt extinguishment accounting, we recorded a loss on extinguishment of debt of $4,318,000 in our first quarter of 2015. The loss also included $1,232,000 of broker, legal and accounting fees related to the exchange transaction.
	To accommodate the October 2014 debt transactions described above, on October 20, 2014, we entered into supplemental indentures relating to our 8.50% Secured Notes and to our 10.875% Senior Secured Second Lien Notes due 2017 (the “10.875% Notes”). Additionally, on October 20, 2014, we entered into an amendment to our senior secured credit agreement, dated as of September 16, 2011, as previously amended, with PNC Bank, National Association (“PNC Bank”). Under the amendment, PNC Bank consented to the transactions contemplated by the 8.50% New Convertible Notes and the exchange transaction, referred to above.
	8.50% Convertible Notes
	As described previously, on January 15, 2015, we completed a redemption of the existing $39,822,000 aggregate principal amount of 8.50% Convertible Notes. The 8.50% Convertible Notes were issued in February 2011 as part of a tender/exchange pursuant to an indenture dated as of February 11, 2011 and in July 2011 by exchange.
	8.50% Secured Notes
	We currently have outstanding $63,931,000 aggregate principal amount of 8.50% Secured Notes. The 8.50% Secured Notes were originally issued in March 2012 in the aggregate principal amount of $78,931,000. Of that total amount, $38,931,000 aggregate principal amount of 8.50% Secured Notes was issued pursuant to an effective registration statement relating to an offer to purchase for cash or exchange for new securities any and all of our outstanding 3.25% Convertible Subordinated Notes due 2026.  The remaining $40,000,000 aggregate principal amount of 8.50% Secured Notes was issued in a private placement that included the issuance of warrants to purchase 3,869,000 shares of our common stock.  The warrants were exercisable on a cashless basis for $.01 per share for ten years after their issuance.  The total purchase price for the 8.50% Secured Notes and warrants issued in the private placement was $39,400,000. The fair value of the warrants was recorded in additional paid-in capital in the amount of $8,489,000. As of May 2013, all 3,869,000 warrants had been exercised and no warrants remain outstanding.
	The 8.50% Secured Notes bear interest at a rate of 8.50% per annum, payable semi-annually in arrears on January 15 and July 15 of each year, beginning July 15, 2012, and mature on January 15, 2017, unless redeemed or repurchased in accordance with their terms. The 8.50% Secured Notes are secured by liens on all assets securing our existing or future senior secured credit facilities (other than certain excluded assets), which liens rank junior in priority to any liens securing our senior secured credit facilities and other permitted priority liens.
	We may redeem all or part of the 8.50% Secured Notes at any time by paying 100% of the principal amount redeemed, plus a make-whole premium (and accrued and unpaid interest on the principal amount redeemed to) as of the date of redemption (subject to the rights of holders of the 8.50% Secured Notes on the relevant record date to receive interest due on the relevant interest payment date as and to the extent provided in the indenture). The indenture governing the 8.50% Secured Notes contains certain covenants that, among other things, will limit our and our restricted subsidiaries’ ability to incur additional indebtedness, pay dividends on or make distributions in respect of capital stock or make certain other restricted payments or investments, enter into agreements that restrict distributions from restricted subsidiaries, sell or otherwise dispose of assets, including capital stock of restricted subsidiaries, enter into transactions with affiliates, create or incur liens and enter into operating leases.
	As described previously, on October 23, 2014, we entered into an agreement for the private exchange of $15,000,000 aggregate principal amount of our 8.50% Secured Notes held by a certain holder for 2,500,000 shares of our common stock and warrants to purchase an additional 2,500,000 shares of our common stock on a cashless basis at an exercise price of $0.01 per share. On November 25, 2014, 1,250,000 warrants were exercised which resulted in the issuance of 1,246,493 shares of common stock. On January 15, 2015, the remaining 1,250,000 warrants were exercised which resulted in the issuance of 1,246,428 shares of common stock and no warrants remain outstanding.
	10.875% Notes
	On January 22, 2013, we issued $12,200,000 aggregate principal amount of the 10.875% Notes for a total purchase price of $11,590,000. The 10.875% Notes were issued in a private placement pursuant to an indenture dated as of January 22, 2013, and bear interest at a rate of 10.875% per annum, payable semi-annually in arrears on January 15 and July 15 of each year, beginning July 15, 2013. The 10.875% Notes are secured by liens on all assets securing our senior secured credit facilities (other than capital stock of subsidiaries of our company to the extent that inclusion of such capital stock would require the filing of separate financial statements for such subsidiaries with the SEC), which liens rank junior in priority to the liens securing our senior secured credit facilities and other permitted priority liens and on an equal and ratable basis with the liens securing our 8.50% Secured Notes. The 10.875% Notes are scheduled to mature on January 15, 2017, unless redeemed or repurchased in accordance with their terms. We may redeem all or a portion of the 10.875% Notes at any time by paying 100% of the principal amount redeemed, plus a make-whole premium as of, and accrued and unpaid interest to, the date of redemption.
	To accommodate the January 2013 debt transactions, on January 22, 2013, we entered into (i) a first supplemental indenture to the indenture dated as of March 30, 2012, which governs the 8.50% Secured Notes, and (ii) a consent and third amendment to our revolving credit and security agreement.
	Debt refinancing costs of $359,000 were capitalized and are being amortized over four years or until the maturity date. The amortization expense is included in interest expense.
	Senior Secured Credit Facility
	On September 22, 2014, we entered into an amendment to our existing senior secured credit facility dated as of September 16, 2011, as previously amended, with PNC Bank. The amendment reduced the maximum principal amount of the revolving credit facility provided by the credit agreement from $35,000,000 to $20,000,000, extended the maturity date of the senior secured credit facility from October 1, 2014 to December 1, 2016, reduced the cash balance we are required to maintain in an account at PNC Bank from $15,000,000 to $2,500,000, and modified the fixed charge coverage covenant under the credit agreement by eliminating the requirement for the four fiscal quarters ending September 28, 2014 and changing the measurement periods thereafter for the fixed charge coverage covenant by excluding from such measurement periods all fiscal quarters ended on or prior to September 28, 2014.
	The September 2014 amendment also required us to maintain cash on our balance sheet, including restricted cash, during the period from December 1, 2014 through January 16, 2015 (which is the day after the 2015 put date for our 8.50% Convertible Notes) and during the period from December 1, 2015 through January 16, 2016 (which is the day after the 2016 put date for our 8.50% Convertible Notes) in an amount not less than the aggregate principal amount of our 8.50% Convertible Notes then outstanding, and to establish a reserve against our borrowing base during each such period in the same amount. The amendment permits us to redeem, repurchase or repay our 8.50% Convertible Notes in whole or in part at any time as long as, after giving effect to such redemption, repurchase or repayment, no default or event of default exists under the credit agreement and we have liquidity of not less than $20,000,000, and permits us to incur additional unsecured debt at any time prior to January 15, 2016 in an amount not to exceed the aggregate principal amount of our 8.50% Convertible Notes then outstanding as long as certain conditions are satisfied, including a requirement that, by the next put date for our 8.50% Convertible Notes, we reduce the aggregate principal balance of our 8.50% Convertible Notes by an amount equal to the principal amount of such additional unsecured debt then outstanding. This portion of the amendment no longer applies as we completed a redemption of the existing $39,822,000 of 8.50% Convertible Notes on January 15, 2015.
	On April 30, 2015, we entered into an amendment to our existing senior secured credit facility dated as of September 16, 2011, as previously amended, with PNC Bank to maintain compliance with a financial covenant of our credit facility. The amendment (i) modifies the fixed charge coverage covenant under our credit agreement to eliminate the requirement for our quarter ended March 29, 2015 and quarters ending June 28, 2015 and September 27, 2015 and change the measurement periods starting with our quarter ending December 27, 2015 by excluding from such measurement periods all quarters ended on or prior to September 27, 2015, and (ii) implements an additional earnings before interest, taxes, depreciation and amortization (“EBITDA”) covenant for our quarter ended March 29, 2015 and quarters ending June 28, 2015 and September 27, 2015.
	Our credit agreement with PNC Bank and the indentures governing the 8.50% Secured Notes and the 10.875% Notes each contain certain covenants that, among other things, limit our and our restricted subsidiaries’ ability to incur additional indebtedness; pay dividends on or make distributions in respect of capital stock or make certain other restricted payments or investments; enter into agreements that restrict distributions from restricted subsidiaries; sell or otherwise dispose of assets, including capital stock of restricted subsidiaries; enter into transactions with affiliates; create or incur liens; enter into operating leases; merge, consolidate or sell substantially all of our assets; make capital expenditures; change the nature of our business; and expend the assets or free cash flow of certain subsidiaries. The indentures also limit the amount of our consolidated total assets and free cash flow that can be attributable to subsidiaries that have not guaranteed the 8.50% Secured Notes or, in certain cases, have not pledged their stock to secure the 8.50% Secured Notes.
	From time to time, we borrow funds under the senior secured credit facility. As of March 29, 2015, we had no outstanding balance. Our average outstanding balance in the twenty-six weeks ended March 29, 2015 was $780,000. Amounts borrowed under the credit facility bear cash interest at a reduced rate equal to, at our election, either (i) PNC Bank’s alternate base rate plus 1.0% per annum, or (ii) LIBOR plus 3.5% per annum if no defaults or events of default exist under the credit agreement. The credit agreement contains certain financial covenants that require us to maintain a minimum fixed charge coverage ratio, minimum EBITDA and minimum liquidity. If we are unable to generate sufficient operating results in future quarters, we may not be able to comply with financial covenants in the credit agreement in future quarters. If necessary, we intend to negotiate a waiver of any noncompliance or an amendment of the financial covenant specific to the applicable period.
	PNC Term Loan
	On December 23, 2014, we entered into an amendment to our existing senior secured credit facility dated as of September 16, 2011, as previously amended, with PNC Bank, as agent and lender.
	Pursuant to the amendment, a term loan was made to us in the amount of $15,000,000. The same covenants in our credit facility with PNC Bank apply to this term loan. The term loan may consist of domestic rate loans, with a per annum interest rate equal to PNC Bank’s alternate base rate (as defined in the credit agreement) plus 2.50%, or LIBOR rate loans, with a per annum interest rate equal to 3.50% plus the greater of the LIBOR rate (as defined in the credit agreement) or 1.00%, or a combination thereof. As a result, our interest rate for the term loan has been 4.5%. The principal balance of the term loan is payable in quarterly installments of $750,000 on the first day of each calendar quarter, commencing on April 1, 2015 and continuing through January 1, 2020.  In the event that the senior secured credit facility is not extended beyond December 1, 2016, the balance due on the term loan also will become due on December 1, 2016. Once repaid, amounts borrowed under the term loan may not be reborrowed.

	We and certain users of our products have from time to time received, and may in the future receive, communications from third parties asserting patents against us or our customers which may relate to certain of our manufacturing equipment or products or to products that include our products as a component. In addition, certain of our customers have been sued on patents having claims closely related to products sold by us. If any third party makes a valid infringement claim and a license was not available on terms acceptable to us, our operating results could be adversely affected. We expect that, as the number of patents issued continues to increase, and as we grow, the volume of intellectual property claims could increase. We may need to engage in litigation to enforce patents issued or licensed to us, protect trade secrets or know-how owned by us or determine the enforceability, scope and validity of the intellectual property rights of others. We could incur substantial costs in such litigation or other similar legal actions, which could have a material adverse effect on our results of operations.
	We are a party from time to time to ordinary routine litigation incidental to our business. The outcome of such claims, if, any, is not expected to materially affect our current or future financial position or results of operations.

Disclosure Text Block Supplement [Abstract]
Asset Impairment Charges [Text Block]	(9)  ASSET IMPAIRMENT
	When indicators of impairment exist and assets are held for use, we estimate future undiscounted cash flows attributable to the assets. In the event such cash flows are not expected to be sufficient to recover the recorded value of the assets, the assets are written down to their estimated fair values based on the expected discounted future cash flows attributable to the assets or based on appraisals. Factors affecting impairment of assets held for use include the ability of the specific assets to generate positive cash flows. Changes in any of these factors or changes in our forecast model estimates could necessitate impairment recognition in future periods for other assets held for use.
	In connection with the consolidation of our operations, two of our facilities were offered for sale or lease in 2013, including the Eau Claire, Wisconsin assembly building and the Development Center building on our Hutchinson, Minnesota campus. During the first quarter of 2014, we received third-party interest in purchasing the Eau Claire assembly building. Based on the discussions regarding the potential sale of this building, we modified our forecast model to increase the probability of a sale of our Eau Claire assembly building and decrease the probability of a lease. Using these new weightings for sale and lease, the carrying value of our assets exceeded the expected undiscounted cash flows indicating a trigger of potential impairment. As a result, we evaluated the recoverability of the Eau Claire assembly building based on these circumstances and recorded an impairment charge of $4,470,000 included in the line item “Asset impairment” in our condensed consolidated statement of operations. The building and related assets had remaining useful lives ranging from 15 to 30 years. We determined the long-lived assets did not meet the criteria to be classified as assets held for sale. During the second quarter of 2014, we sold the Eau Claire, Wisconsin assembly building, and related real and personal property for net proceeds of $4,364,000.

	In recent years, we had multiple severance and manufacturing consolidation and restructuring plans in place to support efforts to improve operating results and liquidity through improved utilization of our facilities in both the U.S. and Thailand.
	During the second quarter of 2014, as part of shutting down our Eau Claire, Wisconsin assembly operations and our continued consolidation efforts, we identified approximately 70 positions to be eliminated. This resulted in an estimated $366,000 of severance expense in the second quarter of 2014.
	During the third quarter of 2014, we identified approximately 100 additional positions to be eliminated at our Eau Claire, Wisconsin and Hutchinson, Minnesota sites to further reduce costs.  This resulted in $1,339,000 of severance expense in the third quarter of 2014.
	During the fourth quarter of 2014, we retained approximately 40 of the previously identified positions for manufacturing of our shape memory alloy optical image stabilization product. All severance and benefits amounts owed have been paid in full.
	In connection with the consolidation of our operations, we incurred site consolidation expenses of $178,000 during the twenty-six weeks ended March 29, 2015 and $876,000 during the twenty-six weeks ended March 30, 2014. The site consolidation expenses consisted primarily of internal labor and contractors.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	(12)  INCOME TAXES
	As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These temporary differences result in deferred tax assets and liabilities, which are included within our consolidated balance sheets. We must then assess the likelihood that our deferred tax assets will be realized based on future taxable income, and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or change this allowance in a period, we must include an expense or a benefit within the tax provision in our consolidated statements of operations.
	Significant judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our deferred tax assets. Valuation allowances arise due to the uncertainty of realizing deferred tax assets. At September 28, 2014, we had a valuation allowance of $227,219,000. We assess whether valuation allowances should be established against our deferred tax assets based on the consideration of all available evidence, using a “more likely than not” standard. In making such assessments, significant weight is to be given to evidence that can be objectively verified. Our current or previous losses are given more weight than our future outlook. Our three-year historical cumulative loss was a significant negative factor. This loss, combined with uncertain near-term market and economic conditions, reduced our ability to rely on our projections of future taxable income in determining whether a valuation allowance was appropriate. Accordingly, we concluded that a full valuation allowance was appropriate. We will continue to assess the likelihood that our deferred tax assets will be realizable, and our valuation allowance will be adjusted accordingly, which could materially impact our financial position and results of operations.
	The income tax benefit for the twenty-six weeks ended March 29, 2015, was $113,000, compared to the income tax benefit of $791,000 for the twenty-six weeks ended March 30, 2014. For the twenty-six weeks ended March 29, 2015, the net benefit of $113,000 is made up of a credit for the expected refund of previously paid U.S. Federal Alternative Minimum Tax, offset primarily by various foreign withholding and income taxes we incur. For the twenty-six weeks ended March 30, 2014, we recognized an $859,000 benefit due to reserves for certain tax refunds that were released due to the expiration of the applicable statute of limitations.

	Our 2011 Equity Incentive Plan has been approved by shareholders and authorizes the issuance of 1,200,000 shares of our common stock (plus any shares that remained available on that date for future grants under our 1996 Incentive Plan) for equity-based awards (no further awards will be made under our 1996 Incentive Plan). Under the equity incentive plans, stock options have been granted to employees, including our officers, and to our directors, at an exercise price not less than the fair market value of our common stock at the date the options are granted. The options granted generally expire ten years from the date of grant or at an earlier date as determined by the committee of our board of directors that administers the plans. Options granted under the plans prior to November 2005 generally were exercisable one year from the date of grant. Options granted under the plans from November 2005 to October 2011 are exercisable two to three years from the date of grant. Options granted under the plans since November 2011 are exercisable one to three years from the date of grant.
	Under our equity incentive plan, we also have issued restricted stock units (“RSUs”) to employees, including our officers. RSUs generally vest over three years in annual installments commencing one year after the date of grant. We recognize compensation expense for the RSUs over the service period equal to the fair market value of the RSUs on the date of issuance. Upon vesting, RSUs convert to shares in accordance with the terms of the equity incentive plan under which they were issued.
	We recorded stock-based compensation expense related to our stock options, RSUs and common stock, included in selling, general and administrative expenses, of $661,000 and $224,000 for the twenty-six weeks ended March 29, 2015, and March 30, 2014, respectively. As of March 29, 2015, $2,871,000 of unrecognized compensation expense related to non-vested awards is expected to be recognized over a weighted-average period of approximately 22 months.
	We use the Black-Scholes option pricing model to determine the weighted-average fair value of options. The weighted-average fair value of options granted during the twenty-six weeks ended March 29, 2015, and March 30, 2014, was $2.42 and $2.34, respectively. The fair value of options at the date of grant and the weighted-average assumptions utilized to determine such values are indicated in the following table:
			Twenty-Six Weeks Ended

	Expected volatility			70	%			80	%
	Expected life (in years)			8				8
	Dividend yield			–				–
	The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected life of our stock options. We considered historical data in projecting expected stock price volatility. We estimated the expected life of stock options and stock option forfeitures based on historical experience.

Earnings Per Share [Text Block]	(14)  LOSS PER SHARE
	Basic loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the year. Diluted loss per share identifies the dilutive effect of potential common shares using net loss available to common shareholders and is computed using the treasury stock method for outstanding stock options and the if-converted method for the 8.50% Convertible Notes and the 8.50% New Convertible Notes.
	A reconciliation of these amounts is as follows:

Diluted loss per share for the thirteen weeks ended March 30, 2014, excludes potential common shares and warrants of 532,000 using the treasury stock method, and 4,630,000 using the if-converted method for the 8.50% Convertible Notes, as they were anti-dilutive.  Diluted loss per share for the twenty-six weeks ended March 29, 2015, excludes potential common shares of 380,000 using the treasury stock method, and 11,429,000 using the if-converted method for the 8.50% Convertible Notes and the 8.50% New Convertible Notes, as they were anti-dilutive. Diluted loss per share for the twenty-six weeks ended March 30, 2014, excludes potential common shares and warrants of 489,000 using the treasury stock method, and 4,630,000 using the if-converted method for the 8.50% Convertible Notes, as they were anti-dilutive.
	As discussed in Note 6, on October 23, 2014, we issued 2,500,000 shares of common stock and warrants to purchase 2,500,000 shares of our common stock as part of an exchange transaction.  On November 25, 2014, 1,250,000 warrants were exercised which resulted in the issuance of 1,246,493 shares of common stock. On January 15, 2015, the remaining 1,250,000 warrants were exercised which resulted in the issuance of 1,246,428 shares of common stock and no warrants remain outstanding.
	As discussed in Note 6, in March 2012, we issued warrants to purchase 3,869,000 shares of our common stock in a private placement.  As of May 2013, all 3,869,000 warrants had been exercised and no warrants remain outstanding.

	The following tables present our assets that are measured at fair value on a recurring basis at March 29, 2015, and September 28, 2014:

	Assets:
	Available-for-sale securities		$	965	$	–	$	–	$	965
	Available-for-Sale Securities
	Our available-for-sale securities are comprised of United States government debt securities. The fair value is based on quoted market prices in active markets.
	Debt
	The fair values of our 8.50% Convertible Notes and 8.50% Secured Notes were determined based on the closing market price of the respective Notes as of the end of the fiscal quarter. The fair value of the 8.50% Convertible Notes and 8.50% Secured Notes was classified in Level 1 of the fair value hierarchy.
	Our 10.875% Notes have not experienced trading activity; therefore the fair value estimate was based on the closing market prices of comparable debt as of the end of the fiscal quarter. Our 8.50% New Convertible Notes have not experienced trading activity; therefore the fair value estimate was based on market variables combined with variables specific to our notes to determine the theoretical value. The fair value of the 10.875% Notes and the 8.50% New Convertible Notes were classified in Level 2 of the fair value hierarchy.
	The fair value of the PNC Bank credit facility and term loan’s carrying values are a reasonable estimate of fair value because of their short-term nature. The fair value measurement for the credit facility and term loan was classified in Level 2 of the fair value hierarchy.
	The estimated fair values of our debt were as follows on each of the indicated dates:
			29-Mar-15				28-Sep-14
			Carrying		Fair Value		Carrying		Fair Value
			Amount				Amount
	8.50% Convertible Notes		$	–	$	–	$	39,822	$	39,125
	8.50% Secured Notes			63,931		63,611		78,931		79,720
	10.875% Notes			12,200		12,959		12,200		13,025

	Credit facility			–		–		9,533		9,533
	Other
	Our financial instruments other than those presented in the disclosures above, include accounts receivable, accounts payable, and other payables. The carrying value of accounts receivable, accounts payable, and other payables approximate fair value because of the short-term nature of these instruments. The fair values of these items were classified in Level 1 of the fair value hierarchy.
	Nonrecurring Fair Value Measurements
	Certain assets are measured at fair value on a nonrecurring basis. These assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances.  These include certain long-lived assets that are written down to fair value when they are determined to be impaired. In the first quarter of 2014, we recognized an impairment of $4,470,000 related to our Eau Claire assembly building using a valuation methodology based on Level 3 inputs.  See Note 9 to the consolidated financial statements for additional details regarding this impairment.
