Fair Value Disclosures [Text Block]	3. Fair values of assets and liabilities Fair value is defined as, “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price).” The accounting standards establish a consistent framework for measuring fair value and disclosure requirements about fair value measurements and among other things, require us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value hierarchy The accounting standards discuss valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The standards utilize a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: ● Level 1 ● Level 2 ● Level 3 Determination of fair value Our cash equivalents and marketable securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. The types of marketable securities valued based on quoted market prices in active markets include most U.S. government and agency securities, sovereign government obligations, money market securities and certain corporate obligations with high credit ratings and an ongoing trading market. The tables below present the balances of our assets and liabilities measured at fair value on a recurring basis as of August 1, 2015 and January 31, 2015 (in thousands): August 1 , 201 5 Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Corporate bonds $ 16,236 $ 16,236 $ - $ - Money market funds 261 261 - - Fixed income mutual funds 1,283 1,283 - - Total cash equivalents and marketable securities 17,780 17,780 - - Restricted cash 400 400 - - Total assets measured at fair value $ 18,180 $ 18,180 $ - $ - January 31 , 201 5 Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Corporate bonds $ 9,283 $ 9,283 $ - $ - Money market funds 7,650 7,650 - - Fixed income mutual funds 1,313 1,313 - - Total cash equivalents and marketable securities 18,246 18,246 - - Restricted cash 400 400 - - Total assets measured at fair value $ 18,646 $ 18,646 $ - $ - Assets measured and recorded at fair value on a non-recurring basis Our non-marketable preferred stock investments in privately-held venture capital funded technology companies are recorded at cost and are adjusted to fair value only in the event that they become other-than-temporarily impaired. As of August 1, 2015, we held equity investments in three privately-held venture capital funded technology companies and an equity investment in one joint venture, with an aggregate carrying value of $3.1 million. In the fourth quarter of fiscal 2014, the second quarter of fiscal 2015 and the second quarter of fiscal 2016, we recorded impairment charges of $0.3 million, $0.6 million and $0.1 million, respectively, on an investment as we concluded the impairment to be other-than-temporary, effectively nullifying any value from this investment as of August 1, 2015. We did not identify any other events or changes in circumstances that may have had a significant adverse effect on the fair value of these investments during the three and six months ended August 1, 2015 and August 2, 2014. Each of these equity investments in privately-held companies constituted less than a 20% ownership position. Furthermore, we do not believe that we have the ability to exert significant influence over any of these companies.

In the fourth quarter of fiscal 2010, we purchased additional shares of preferred stock in Issuer A at a cost of $1.0 million. In November 2010, we loaned $1.0 million to Issuer A and received a secured promissory note. During the second quarter of fiscal 2015, the remaining balance of the note receivable from Issuer A was fully repaid. In the third quarter of fiscal 2011, we purchased shares of preferred stock in another privately-held technology company (“Issuer B”) at a total investment cost of $1.0 million. In the fourth quarter of fiscal 2011, we purchased shares of preferred stock in another privately-held technology company (“Issuer C”) at a total investment cost of $1.0 million. In the fourth quarter of fiscal 2014, the second quarter of fiscal 2015 and the second quarter of fiscal 2016, we recorded impairment charges of $0.3 million, $0.6 million and $0.1 million, respectively, on this investment as we concluded the impairment to be other-than-temporary, effectively nullifying any value from this investment as of August 1, 2015. In the third quarter of fiscal 2012, we made an equity investment of $0.1 million in a privately-held joint venture (“Issuer D”). We made the aforementioned investments because we viewed the issuer as either having strategic technology or a business that would complement our technological capabilities or help create an opportunity for us to sell our chipset solutions. We analyze each investment quarterly for evidence of impairment. Our President and Chief Executive Officer is a member of the Board of Directors of both Issuer A and Issuer B. In the case of Issuer B, the investment transaction was negotiated without the personal involvement of the executive officer who had a personal interest in the transaction.

Restructuring and Related Activities Disclosure [Text Block]	7. Restructuring costs In fiscal 2013, as a result of significant expansion in our infrastructure and operational activities in connection with purchases and acquisitions that took place between fiscal years 2008 and 2013, and in response to certain redundancies, underperforming operations and delays in programs and product releases, we implemented a restructuring program to realign our global operating expenses with our new business conditions, and to improve efficiency, competitiveness and profitability. Costs relating to facilities closure or lease commitment are recognized when the facility has been exited. Termination costs are recognized when the costs are deemed both probable and estimable and after notification to impacted employees has occurred. During the first quarter of fiscal 2016, we incurred restructuring charges of less than $0.1 million, substantially all of which was related to facility exit cost adjustments, which was reflected in operating expenses. During the second quarter of fiscal 2016, we incurred no restructuring charges. In the first quarter of fiscal 2015, we incurred restructuring charges of $1.0 million, all of which was related to workforce reductions of 29 employees across several geographic regions, the majority of which were in our operations in Israel. Of the total restructuring charges recorded in the first fiscal quarter, approximately $0.1 million was reflected in cost of revenue and $0.9 million was reflected in operating expenses. During the second quarter of fiscal 2015, we incurred less than $0.1 million of restructuring charges. Expenses recognized for restructuring activities impacting our operating expenses are included in “Restructuring costs” in the condensed consolidated statements of operations. Our restructuring measures could negatively impact our revenue and results of operations in the future as a result of less employees developing future products and working to sell our products. A combined summary of the recent activity of the restructuring plans initiated by us is as follows (in thousands): Workforce Reduction Asset Impairment Facility Exit Costs Total Cumulative Restructuring Costs Liability, February 1, 2014 $ 363 $ - $ 2 $ 365 $ 5,570 Charges in fiscal 2015 1,083 - (20 ) 1,063 1,063 Cash payments (1,382 ) - 8 (1,374 ) - Non-cash items 38 - 10 48 - Liability, January 31, 2015 102 - - 102 6,633 Charges for the six months ended August 1, 2015 3 - 6 9 9 Cash payments (3 ) - (7 ) (10 ) - Non-cash items - 1 1 - Liability, August 1, 2015 $ 102 $ - $ - $ 102 $ 6,642

Mergers, Acquisitions and Dispositions Disclosures [Text Block]	8. Sale of development project On March 8, 2013, we entered into an Asset Purchase Agreement with a third party (the “Buyer”) to sell certain development projects (intellectual property) and long-lived assets (the “Connectivity Assets”) related to the connectivity technology over coaxial cable market, including the transfer of 21 employees (the “Connectivity Employees”) to the Buyer. The aggregate carrying amount of the Connectivity Assets ultimately transferred was approximately $0.6 million and were classified as assets held for sale in prepaid expenses and other current assets in the consolidated balance sheet at February 2, 2013. We received an initial payment of $2.0 million in cash at the closing of the transaction and a payroll expense reimbursement payment of $0.6 million (as described more fully below). Under the terms of the Asset Purchase Agreement, if certain technical milestones were met by September 30, 2013 as a result of further development of the transferred technology by the Buyer, we were to be paid an additional $5.0 million in cash. In April 2013, upon receiving the closing consideration of $2.0 million, we recorded a gain of $1.1 million, net of the carrying value of the Connectivity Assets and fees for legal and bank services of approximately $0.4 million. The gain is included in “Gain on sale of development project” in the consolidated statements of operations for fiscal 2014. Additionally, in April 2013, in connection with the Asset Purchase Agreement, the Buyer reimbursed us for payroll expenses related to the employees transferred to the Buyer for the period from February 1, 2013 through the actual payroll transfer, totaling $0.6 million. As the contingent consideration was uncertain at the time of the initial sale, we did not recognize the contingent payment. The Buyer advised us that it did not believe the milestones had been met by the deadline of September 30, 2013. On May 19, 2014, the parties amended the Asset Purchase Agreement to require the use of Judicial Arbitration and Mediations Services (“JAMS”) for arbitration to settle the dispute between the parties. We pursued our rights to the milestone consideration payment through the alternative dispute resolution provisions set forth in the amendment. On September 5, 2014, the Buyer filed counterclaims in response to our claims arising from the Asset Purchase Agreement. Arbitration regarding this dispute took place on June 1, 2015. In August 2015, we prevailed on all of the claims we asserted against the Buyer, and all of the Buyer’s counterclaims against us were denied. We were awarded $5.0 million plus reimbursement of reasonable legal costs and interest. We are in the process of determining the amount of legal fees we are entitled to recover. Upon receipt of the rewarded amount from the Buyer, we will recognize the amount as other income in our consolidated statements of operations in its entirety.

Commitments and Contingencies Disclosure [Text Block]	9. Commitments and contingencies Commitments Product warranty In general, we sell products with up to a one-year limited warranty that our products will be free from defects in materials and workmanship. Warranty cost is estimated at the time revenue is recognized based on historical activity, and additionally, for any specific known product warranty issues. Accrued warranty cost includes hardware repair and/or replacement and is included in accrued liabilities in the accompanying condensed consolidated balance sheets. Details of the change in accrued warranty as of August 1, 2015 and August 2, 2014 are as follows (in thousands): Three Months Ended Balance Beginning of Period Additions and Adjustments Deductions Balance End of Period August 1, 2015 $ 861 $ 150 $ (137 ) $ 874 August 2, 2014 $ 630 $ 117 $ (107 ) $ 640 Six Months Ended Balance Beginning of Period Additions and Adjustments Deductions Balance End of Period August 1, 2015 $ 864 $ 290 $ (280 ) $ 874 August 2, 2014 $ 620 $ 241 $ (221 ) $ 640 Purchase commitments We place non-cancelable orders to purchase semiconductor products from our suppliers on an eight to twelve week lead-time basis. As of August 1, 2015, the total amount of outstanding non-cancelable purchase orders was approximately $35.3 million. Design Tools We entered into an agreement with a vendor to purchase $12.9 million of design tools. Payments under this agreement are being made on a quarterly basis from June 2013 through March 2016. As of August 1, 2015, the remaining payments under this agreement totaled $4.1 million. In addition to this agreement, we have entered into other purchase arrangements for certain design tools which totaled $3.0 million. Payments under these arrangements are being made through fiscal 2017. We have fully accrued these amounts as of August 1, 2015. Royalties We pay royalties for the right to sell certain products under various license agreements. During the three and six months ended August 1, 2015, we recorded gross royalty expense of $1.3 million and $2.1 million, respectively, and $0.5 million and $1.1 million for the three and six months ended August 2, 2014, respectively, in cost of revenue in the condensed consolidated statements of operations. Our wholly owned subsidiary, Sigma Designs Israel SDI Ltd. (formerly Coppergate Communications, Ltd.), participated in programs sponsored by the Office of the Chief Scientist of Israel's Ministry of Industry, Trade and Labor, or the OCS, for the support of research and development activities that we conducted in Israel. Through August 1, 2015, we had obtained grants from the OCS aggregating to $5.2 million of our research and development projects in Israel. We completed the most recent of these projects in 2013. We are obligated to pay royalties to the OCS, amounting up to 4.5% of the sales of certain products up to an amount equal to the grants received, plus LIBOR-based interest. As of August 1, 2015, our remaining potential obligation under these programs was approximately $1.1 million. Contingencies Litigation From time to time, we are involved in claims and legal proceedings that arise in the ordinary course of business. We expect that the number and significance of these matters will increase as our business expands. In particular, we could face an increasing number of patent and other intellectual property claims as the number of products and competitors in our industry grows. Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources or cause us to enter into royalty or licensing agreements which, if required, may not be available on terms favorable to us. If an unfavorable outcome were to occur against us, there exists the possibility of a material adverse impact on our financial position and results of operations for the period in which the unfavorable outcome occurs and, potentially, in future periods. On March 8, 2013, we entered into an Asset Purchase Agreement with a third party (the “Buyer”) to sell certain development projects (intellectual property) and long-lived assets (the “Connectivity Assets”) related to the connectivity technology over coaxial cable market, including the transfer of 21 employees (the “Connectivity Employees”) to the Buyer. Under the terms of the Asset Purchase Agreement, if certain technical milestones were met by September 30, 2013 as a result of further development of the transferred technology by the Buyer, we were to be paid an additional $5.0 million in cash. The Buyer advised us that it did not believe the milestones had been met by September 30, 2013. On May 19, 2014, the parties amended the Asset Purchase Agreement to require the use of JAMS for arbitration to settle the dispute between the parties. We pursued our rights to the milestone consideration payment through the alternative dispute resolution provisions set forth in the amendment. On September 5, 2014, the Buyer filed counterclaims in response to our claims arising from the Asset Purchase Agreement. Arbitration regarding this dispute took place on June 1, 2015. In August 2015, we prevailed on all of the claims we asserted against the Buyer, and all of the Buyer’s counterclaims against us were denied. We were awarded $5.0 million plus reimbursement of reasonable legal costs and interest. We are in the process of determining the amount of legal fees we are entitled to recover. Upon receipt of the rewarded amount from the Buyer, we will recognize the amount as other income in our consolidated statements of operations in its entirety. Indemnifications In certain limited circumstances, we have agreed and may agree in the future to indemnify certain customers against patent infringement claims from third parties related to our intellectual property. In these limited circumstances, the terms and conditions of sale generally limit the scope of the available remedies to a variety of industry-standard methods including, but not limited to, a right to control the defense or settlement of any claim, procure the right for continued usage, and a right to replace or modify the infringing products to make them non-infringing. To date, we have not incurred or accrued any significant costs related to any claims under such indemnification provisions. Our articles of incorporation and bylaws require that we indemnify our officers and directors against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services to us. In addition, we have entered into separate indemnification agreements with each of our directors and executive officers, which provide for indemnification of these individuals under similar circumstances and under additional circumstances. The indemnification obligations are more fully described in our charter documents and the form of indemnification agreement filed with our SEC reports. We purchase insurance to cover claims or a portion of the claims made against our directors and officers. Since a maximum obligation is not explicitly stated in our charter documents or in our indemnification agreements and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated. The fair value of these obligations was zero on our condensed consolidated balance sheet as of August 1, 2015. Third-party licensed technology We license technologies from various third parties and incorporate that technology into our products. Some of these licenses require us to pay royalties and others require us to report sales activities so that royalties may be collected from our customers. From time to time, we are audited by licensors of these technologies for compliance with the terms of these licenses. In the first quarter of fiscal 2015, we settled an audit through binding arbitration relating to a license agreement used in our Set-top Box business for $0.2 million, $0.1 million of which was incurred during the three months ending May 3, 2014 and was included in sales and marketing expenses in the accompanying condensed consolidated statements of operations. 15 SIGMA DESIGNS, INC. NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued) We could be required to make additional payments as a result of pending or future compliance audits. For license agreements where we have royalty obligations, we charge any settlement payments that we make in connection with audits to cost of revenue. For license agreements where we simply have reporting obligations, we treat any settlement payments as penalties and charge the amounts to operating expenses in sales and marketing. During the second quarter of fiscal 2015, we were notified by one of our licensors of their intent to audit for compliance with the terms of the license. As of August 1, 2015, the audit process has been completed for which the licensor subsequently remitted preliminary information to us indicating the potential for additional payments may be required. We are still in the process of assessing the audit findings along with the licensor. However, based on the preliminary information, we have accrued $0.1 million of additional expenditures in our condensed consolidated statement of operations for the three and six months ended August 1, 2015. We believe we are substantially in compliance with the terms of our licensing arrangements.

Earnings Per Share [Text Block]	10. Earnings per share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the fiscal period. Diluted net loss per share is the same as basic net loss per share as the inclusion of potentially issuable shares is anti-dilutive. Diluted net income per share is computed by adjusting outstanding shares, assuming any dilutive effects of stock incentive awards calculated using the treasury stock method. Under the treasury stock method, an increase in the fair market value of our common stock results in a greater dilutive effect from outstanding stock options, restricted stock units and stock purchase rights. Additionally, the exercise of employee stock options and stock purchase rights and the vesting of restricted stock units results in a further dilutive effect on net income per share. The following table sets forth the basic and diluted net income (loss) per share computed for the three and six months ended August 1, 2015 and August 2, 2014 (in thousands, except per share amounts): Three Months Ended Six Months Ended August 1 , 201 5 August 2 , 201 4 August 1 , 201 5 August 2 , 201 4 Numerator: Net income (loss), as reported $ 296 $ (7,620 ) $ (86 ) $ (17,534 ) Denominator: Weighted-average common shares outstanding - basic 35,604 34,622 35,473 34,459 Dilutive effect of employee stock plans 998 - - - Weighted-average common shares outstanding - diluted 36,602 34,622 35,473 34,459 Net income (loss) per share - basic $ 0.01 $ (0.22 ) $ (0.00 ) $ (0.51 ) Net income (loss) per share - diluted $ 0.01 $ (0.22 ) $ (0.00 ) $ (0.51 ) The weighted-average number of shares outstanding used in the computation of basic and diluted net income (loss) per share does not include the effect of the following potential outstanding shares of common stock.

It is required by the “Procedures of Shanghai Municipality on Endowment Insurance for Town Employees” to provide pension insurance for Shanghai employees. The mandatory plan is managed by the local authority. Under the current plan, the employee will contribute 8.0% of the annual base to the plan and the employer will match 21% of the annual base. For calendar year 2015, the annual base is capped at RMB 16,353 per employee. For the three and six months ended August 1, 2015, we made matching contributions of $0.6 million and $1.1 million, respectively, and $0.5 million and $1.0 million for the three and six months ended August 2, 2014, respectively. Retirement pension plans We maintain retirement pension plans for the benefit of qualified employees in Denmark, Taiwan, the Netherlands, and Germany. We made matching contributions of $0.2 million for each of the three months ended August 1, 2015 and August 2, 2014; and $0.3 million and $0.4 million for the six months ended August 1, 2015 and August 2, 2014, respectively. Severance plan We maintain a severance plan for several Israeli employees pursuant to Israel's Severance Pay Law based on the most recent salary of the employees multiplied by the number of years of employment. Upon termination of employment, employees are entitled to one month salary for each year of employment or a portion thereof. As of August 1, 2015, we have an accrued severance liability of $0.8 million primarily offset by $0.7 million of severance employee funds. 17 SIGMA DESIGNS, INC. NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued) Employee Stock Purchase Plan During the first quarter of fiscal 2016, we discovered that we inadvertently sold shares of our common stock to our employees during fiscal 2015 in excess of the shares of common stock authorized to be issued under our 2010 Purchase Plan. As a result, we may have failed to comply with the registration or qualification requirements of federal securities laws. Certain purchasers of the shares that were issued in excess of the shares authorized under our 2010 Purchase Plan may have the right to rescind their purchases from us for an amount equal to the purchase price paid for shares, plus interest from the date of purchase. These shares were treated as issued and outstanding for financial reporting purposes as of the original date of issuance. We intend to make a registered rescission offer during fiscal 2016 to eligible participants who purchased shares in the last twelve months. As of August 11, 2015, there were approximately 94,436 shares issued to participants in the 2010 Purchase Plan in the past twelve months that continued to be held by the original purchasers of such shares which may be subject to the rescission rights referenced above. All of these shares were originally purchased for $3.89 per share. If holders of all these shares seek to rescind their purchases, we could be required to make aggregate payments of up to approximately $0.4 million, which does not include statutory interest. However, the actual impact to our cash position may be lower depending on the number of holders who accept the rescission offer and tender their shares. Pursuant to the authoritative accounting guidance, the shares are considered mandatorily redeemable as the redemption may be outside of our control. The aforementioned amount is included in accrued compensation and related benefits in the accompanying condensed consolidated balance sheets. The shares subject to repurchase are included in permanent equity as of January 31, 2015 as these shares are legally outstanding with all rights and privileges therein. We also may be subject to civil and other penalties by regulatory authorities as a result of the failure to register these shares with the Securities and Exchange Commission. We do not believe that the failure to register the shares or the planned rescission offer will have a material impact on our condensed consolidated financial statements. We are also evaluating the potential impact to our employees, including potential tax consequences, for issuing shares in excess of the number of shares reserved under our 2010 Purchase Plan. We may incur additional costs associated with any potential tax consequences and during the fourth quarter of fiscal 2015, we accrued $0.4 million of expense associated with these additional costs which were recorded in accrued compensation and related benefits in the accompanying condensed consolidated balance sheets.

Income Tax Disclosure [Text Block]	1 2 . Income taxes We recorded a provision for income taxes of $1.0 million and $2.2 million for the three months ended August 1, 2015 and August 2, 2014, respectively. The provision for income taxes was $3.5 million and $3.6 million for the six months ended August 1, 2015 and August 2, 2014, respectively. The decrease in tax expense is primarily attributable to the decrease in profitability in taxable jurisdictions in the second quarter of fiscal year 2016 as compared to the same period in fiscal year 2015 and changes in tax reserves. During the three and six months ended August 1, 2015 and August 2, 2014, we were unable to reasonably project our annual effective tax rate, and therefore computed our provision for income taxes based on year-to-date actual financial results. Included in our provision for income taxes are foreign exchange gains or losses on unsettled income tax liabilities.

Segment Reporting Disclosure [Text Block]	13. Segment and geographical information Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and in assessing performance. We are organized as, and operate in, one reportable segment. Our operating segment consists of our geographically based entities in the United States, Israel and Singapore. Our chief operating decision-maker reviews consolidated financial information, accompanied by information about revenue by product group, target market and geographic region. We do not assess the performance of our geographic regions on other measures of income, expense or net income. Our net revenue is derived principally from the sales of integrated semiconductor solutions, which we sell across all of our target markets. Smart TV products consist of a range of platforms that are based on highly integrated chips, embedded software, and hardware reference designs. Media Connectivity products consist of wired home networking controller chipsets that are designed to provide connectivity solutions between various home entertainment products and incoming video streams. Set-top Box products consist of connected media processors and players delivering IP streaming video, including hybrid versions of these products. IoT Devices consist of our wireless Z-Wave chipsets and modules. Our License and other markets include revenue derived from the licensing of our technology to third parties and other sources. Revenue derived from other sources includes software development kits, engineering support services for hardware and software, and engineering development for customization of chipsets and other accessories. No revenue was derived from the licensing of our technology during the three and six months ended August 1, 2015, whereas 5.8% and 6.1% of our total net revenue for the three and six months ended August 2, 2014, respectively, was derived from licensing arrangements. Historically, we disclosed information encompassing product groupings by target markets with certain naming conventions, consisting of Digital Television (“DTV”), Set-top Box, Home Networking, Home Control, and License and other. Effective in the fourth quarter of fiscal 2015, we changed the naming conventions of some of our target markets, commensurate with changes taking effect in our industry as a whole. We renamed our “DTV” target market to “Smart TV,” “Home Networking” to “Media Connectivity,” and “Home Control” to “IoT Devices.” These changes did not affect the products or related services categorization, or previously reported amounts related to the aforementioned historical target markets.

Basis of Accounting, Policy [Policy Text Block]	Basis of presentation: The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). They do not include all disclosures required by US 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 January 31, 2015, included in our fiscal 2015 Annual Report on Form 10-K, as filed with the SEC on April 15, 2015, referred to as our fiscal 2015 Annual Report.
