| Accounting Policies [Abstract] | ' |
| Basis of Accounting, Policy [Policy Text Block] | ' |
| Basis of presentation: The consolidated financial statements include the accounts of Sigma Designs, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. We changed our presentation of other comprehensive income due to the adoption of Financial Accounting Standards Board, or FASB, Accounting Standards Codification (ASC) Topic 220, Presentation of Comprehensive Income. The adoption of this accounting standard did not have a material impact on our consolidated financial statements. In May 2012, we completed our acquisition of certain assets from Trident Microsystems, Inc. and certain of its subsidiaries (collectively referred to as “Trident”). The consolidated financial statements include the results of operations of Trident commencing as of the acquisition date. See Note 10 for further discussion. |
| Fiscal Period, Policy [Policy Text Block] | ' |
| Accounting period: We follow a 52 or 53-week fiscal reporting calendar ending on the Saturday closest to January 31 each year. Our most recent fiscal year, fiscal 2014, ended on February 1, 2014, included 52 weeks. The fiscal years 2013 and 2012, ended February 2, 2013 and January 28, 2012 included 53 and 52 weeks, respectively. Our next fiscal year, ending on January 31, 2015, will include 52 weeks. |
| Costs Associated with Exit or Disposal Activities or Restructurings, Policy [Policy Text Block] | ' |
| Restructuring charges: During fiscal 2014 and 2013, we implemented restructuring plans to reorganize our operations and reduce our workforce and related operating expenses. Our restructuring charges include primarily payments to employees for severance, asset impairment charges, termination fees associated with leases and other contracts and other costs related to the closure of facilities. Accruals are recorded when management has approved a plan to restructure operations and a liability has been incurred. The restructuring accruals are based upon management estimates at the time they are recorded. These estimates can change depending upon changes in facts and circumstances subsequent to the date the original liability was recorded. During fiscal 2014 and 2013, we recorded restructuring charges of $2.3 million and $3.3 million, respectively. |
| Use of Estimates, Policy [Policy Text Block] | ' |
| Use of estimates: The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, or US GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. The primary areas that require significant estimates and judgments by management include, but are not limited to, revenue recognition, allowances for doubtful accounts, sales returns, warranty obligations, inventory valuation, stock-based compensation expense, goodwill and purchased intangible asset valuations, strategic investments, deferred income tax asset valuation allowances, uncertain tax positions, tax contingencies, restructuring costs, litigation and other loss contingencies. These estimates and assumptions are based on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ from those estimates, and such differences may be material to our consolidated financial statements. |
| Fair Value of Financial Instruments, Policy [Policy Text Block] | ' |
| Fair value of financial instruments: For certain of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these items. Marketable securities consist of available-for-sale securities that are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income, a component of shareholders’ equity. The fair value of cash equivalents and certain marketable securities is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets. |
| Derivatives, Policy [Policy Text Block] | ' |
| Derivative financial instruments: We account for our financial derivatives as either assets or liabilities and carry them at fair value. We do not use derivative financial instruments for speculative or trading purposes, nor do we hold or issue leveraged derivative financial instruments. We use foreign exchange contracts to hedge certain existing and anticipated foreign currency denominated transactions. Unrealized gains and losses arising from the effective portion of foreign exchange contracts that are designated as cash flow hedging instruments are recorded in accumulated other comprehensive income and are subsequently reclassified into earnings in the same period or periods during which the underlying transactions affect earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. Gains and losses arising from changes in the fair values of foreign exchange contracts that are not designated as hedging instruments are recognized in current earnings. |
| Cash and Cash Equivalents, Policy [Policy Text Block] | ' |
| Cash and cash equivalents: We consider all highly liquid debt instruments with a remaining maturity of 90 days or less at the date of purchase to be cash equivalents. |
| Marketable Securities, Policy [Policy Text Block] | ' |
| Short and long-term marketable securities: Short-term marketable securities represent highly liquid instruments with a remaining maturity date at the end of each reporting period of greater than 90 days but less than one year and are stated at fair value. Long-term marketable securities represent securities with contractual maturities greater than one year from the date of acquisition. We classify our marketable securities as available-for-sale because the sale of such securities may be required prior to maturity. The difference between amortized cost (cost adjusted for amortization of premiums and accretion of discounts, which is recognized as an adjustment to interest income) and fair value, representing unrealized holding gains or losses, are recorded separately as a component of accumulated other comprehensive income within shareholders’ equity. Any gains and losses on the sale of marketable securities are determined on a specific identification basis. We monitor all of our marketable securities for impairment and if these securities are reported to have a decline in fair value, we use significant judgment to identify events or circumstances that would likely have a significant adverse effect on the future value of each investment including: (i) the nature of the investment; (ii) the cause and duration of any impairment; (iii) the financial condition and future prospects of the issuer; (iv) for securities with a reported decline in fair value, our ability to hold the security for a period of time sufficient to allow for any anticipated recovery of fair value; (v) the extent to which fair value may differ from cost; and (vi) a comparison of the income generated by the securities compared to alternative investments. We recognize an impairment charge if a decline in the fair value of our marketable securities is judged to be other-than-temporary. No such impairment charges were recorded in fiscal 2014, 2013 and 2012. |
| Receivables, Policy [Policy Text Block] | ' |
| Accounts receivable and allowances: We defer recognition of revenue and the related receivable when we cannot estimate whether collectability is reasonably assured at the time products and services are delivered to our customer. We also provide allowances for bad debt and sales returns. In establishing the allowance for bad debt, we review the customer’s payment history and information regarding their credit worthiness. In establishing the allowance for sales returns, we make estimates of potential future returns of products for which revenue has been recognized in the current period, including analyzing historical returns, current economic trends and changes in customer demand and acceptance of our products. Our allowance for sales return, discounts and bad debt was $0.3 million and $0.3 million at February 1, 2014 and February 2, 2013, respectively. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, or future product returns increased, additional allowances may be required. |
| Inventory, Policy [Policy Text Block] | ' |
| Inventory: Inventory is stated at the lower of standard cost, which approximates actual cost on a first-in, first-out basis, or market value. We evaluate our ending inventory for excess quantities and obsolescence on a quarterly basis. This evaluation includes analysis of historical and estimated future unit sales by product as well as product purchase commitments that are not cancelable. We develop our demand forecasts based, in part, on discussions with our customers about their forecasted supply needs. However, our customers generally only provide us with firm purchase commitments for the month and quarter and not our entire forecasted period. Additionally, our sales and marketing personnel provide estimates of future sales to prospective customers based on actual and expected design wins. A provision is recorded for inventory in excess of estimated future demand. In addition, we write-off inventory that is obsolete. Obsolescence is determined from several factors, including competitiveness of product offerings, market conditions and product life cycles. Provisions for excess and obsolete inventory are charged to cost of revenue. At the time of the loss recognition, a new, lower-cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. If this lower-cost inventory is subsequently sold, we will realize higher gross margins for those products. |
|
| Inventory write-downs inherently involve assumptions and judgments as to amount of future sales and selling prices. As a result of our inventory valuation reviews, we charged provisions for excess and obsolete inventory of approximately $0.8 million, $7.1 million and $9.0 million to cost of revenue for fiscal 2014, 2013 and 2012, respectively. We have sold through $1.0 million, $3.3 million and $0.6 million of inventory that we had previously recorded as excess and obsolete in fiscal 2014, 2013 and 2012, respectively. Although we believe that the assumptions we use in estimating inventory write-downs are reasonable, significant future changes in these assumptions could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant inventory write-downs. |
| Standard Product Warranty, Policy [Policy Text Block] | ' |
| Warranty: Our products typically carry a one-year limited warranty that 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 software support costs and is included in accrued liabilities on the consolidated balance sheets. Although we engage in extensive product quality programs and processes, our warranty obligation has been and may in the future be affected by product failure rates, product recalls, repair or replacement costs and additional development costs incurred in correcting any product failure. Should actual product failure rates differ from our estimates, additional warranty reserves could be required. In that event, our product gross margins would be reduced. |
| Property, Plant and Equipment, Policy [Policy Text Block] | ' |
| Software, equipment and leasehold improvements: Software, equipment and leasehold improvements are stated at cost. Depreciation and amortization for software, equipment and leasehold improvements is computed using the straight-line method based on the useful lives of the assets (one to five years) or the remaining lease term if shorter. Any allowance for leasehold improvements received from the landlord for improvements to our facilities is amortized using the straight-line method over the lesser of the remaining lease term or the useful life of the leasehold improvements. Repairs and maintenance costs are expensed as incurred. |
| Business Combinations Policy [Policy Text Block] | ' |
| Business combinations: The purchase accounting method applied to business combinations requires us to allocate the purchase price of acquired companies to the identifiable tangible and intangible assets acquired and liabilities assumed, as well as in-process research and development, or IP R&D, based on their estimated fair values. Such valuations require us to make significant estimates and assumptions, especially with respect to intangible assets. The significant purchased intangible assets recorded by us include customer relationships, developed technology, IP R&D and trademarks. Critical estimates and assumptions used in valuing these assets include but are not limited to: future expected cash flows from acquired products, customer relationships and acquired developed technologies and patents; expected costs to develop IP R&D into commercially viable products, calculation of the weighted average cost of capital and expected cash flows from completed projects; assumptions regarding brand awareness and market position, and assumptions about the period of time the brand will continue to be used in our product portfolio; and assumptions about discount rates. The estimated fair values are based upon assumptions that we believe to be reasonable but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. |
| Goodwill and Intangible Assets, Policy [Policy Text Block] | ' |
| Intangible assets: The amounts and useful lives assigned to intangible assets acquired, other than goodwill, impact the amount and timing of future amortization. Intangible assets include those acquired through business combinations and intellectual property that we purchase for incorporation into our product designs. We begin amortizing such intellectual property at the time that we begin shipment of the associated products into which it is incorporated. We amortize the intellectual property over the estimated useful life of the associated products, generally two to three years. |
|
| Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and intangible assets acquired. Other intangible assets primarily represent purchased developed technology, customer relationships, trademarks, non-compete agreements, purchased IP and IP R&D. We currently amortize our intangible assets with definitive lives over periods ranging from two to ten years using a method that reflects the pattern in which the economic benefits of the intangible assets are consumed or otherwise used or, if that pattern cannot be reliably determined, using a straight-line amortization method. We capitalize IP R&D projects acquired as part of a business combination and upon completion of each project, IP R&D assets are reclassified to developed technology and amortized over their estimated useful lives. |
| Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block] | ' |
| Impairment of goodwill and other long-lived assets: We evaluate goodwill on an annual basis as of the last day of our fiscal year or whenever events or changes in circumstances indicate the carrying value may not be recoverable. We first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If we conclude that it is more likely than not that the fair value of a reporting units is less than its carrying amount, we conduct a two-step quantitative goodwill impairment test. The first step requires identifying the reporting units and comparing the fair value of each reporting unit to its net book value, including goodwill. We have identified that we operate one reporting unit and the fair value of our operating unit is determined to be equal to our market capitalization as determined through quoted market prices, adjusted for a reasonable control premium. We estimate the control premium based on a review of acquisitions of comparable semiconductor companies that were completed during the last four years. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, we perform the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The amount, by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. |
|
| During development, IP R&D is not subject to amortization and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. We first assess qualitative factors to determine whether it is more likely than not that the fair value of IP R&D is less than its carrying amount, and if so, we conduct a quantitative impairment test. The impairment test consists of a comparison of the fair value to its carrying amount. If the carrying value exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Once an IP R&D project is complete, it becomes a definite lived intangible asset and is evaluated for impairment in accordance with our policy for long-lived assets. |
|
| We test long-lived assets, including purchased intangible assets (other than goodwill and IP R&D) for impairment whenever events or changes in circumstances, such as a change in technology, indicate that the carrying value of these assets may not be recoverable. If indicators of impairment exist, we determine whether the carrying value of an asset or asset group is recoverable, based on comparisons to undiscounted expected future cash flows that the assets are expected to generate. If an asset is not recoverable, we record an impairment loss equal to the amount by which the carrying value of the asset exceeds its fair value. We primarily use the income valuation approach to determine the fair value of our long-lived assets and purchased intangible assets. |
|
| Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. These estimates and assumptions include forecasts of revenue and operating margins used to calculate projected future cash flows, risk-adjusted discount rates, future economic and market conditions and a determination of appropriate market comparables. We base our fair value estimates on assumptions we believe to be reasonable at that time, however, actual future results may differ from those estimates. Future competitive, market and economic conditions could negatively impact key assumptions including our market capitalization, actual control premiums or the carrying value of our net assets, which could require us to realize an additional impairment. |
| Investment, Policy [Policy Text Block] | ' |
| Long-term investments: Investments in private equity securities of less than 20% owned companies are accounted for using the cost method unless we can exercise significant influence or the investee is economically dependent upon us, in which case the equity method is used. We evaluate our long-term investments for impairment annually or whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. |
| Assets Held for Sale, Policy [Policy Text Block] | ' |
| Assets held for sale: Assets are classified as assets held for sale when their carrying amount is to be recovered principally through a sale transaction rather than through continuing use. The assets are classified as assets to be disposed of by sale when the following conditions have been met: management has approved the plan to sell; assets are available for immediate sale; assets are actively being marketed; sale is probable within one year; price is reasonable in the market and it is unlikely that there will be significant changes in the assets to be sold or a withdrawal to the plan to sell. Assets classified as held for sale are reported as current assets at the lower of their carrying amount or fair value less costs to sell and depreciation is not charged on long-lived assets classified as held for sale. The assets held for sale at February 1, 2014 and February 2, 2013 were zero and $0.6 million, respectively, and is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets. |
| Revenue Recognition, Policy [Policy Text Block] | ' |
| Revenue recognition: We derive our revenue primarily from product sales. Our products, which we refer to as chipsets, consist of highly integrated semiconductors and embedded software that enables real-time processing of digital video and audio content, which we refer to as real-time software. We do not deliver software as a separate product in connection with product sales. We recognize revenue for product sales when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is reasonably assured. These criteria are usually met at the time of product shipment. We record reductions of revenue for estimated product returns in the same period that the related revenue is recorded. The amount of these reductions is based on historical sales returns, analysis of credit memo data, specific criteria included in the agreements, and other factors known at the time. We accrue 100% of potential returns at the time of sale when there is not sufficient historical sales data and recognize revenue when the right of return expires. During the third quarter of fiscal 2014, we adopted prospectively, the authoritative guidance, ASU No. 2010-17, “Revenue Recognition – Milestone Method”, (ASU 2010-17) that provides an alternative method of revenue recognition for milestone payments. Under the milestone method guidance, we recognize revenue that is contingent upon the achievement of a substantive milestone in its entirety in the period in which the milestone is achieved. To be considered substantive, the consideration earned by achieving the milestone should be (a) commensurate with (1) either the vendor’s performance to achieve the milestone or (2) to the enhancement of the value of the item delivered as a result of a specific outcome resulting from the vendor’s performance to achieve the milestone (b) the consideration should relate solely to past performance, and (c) the consideration should be reasonable relative to all deliverables and payment terms in the arrangement. Other milestones that do not fall under the definition of a milestone under the milestone method are recognized under the authoritative guidance concerning revenue recognition. We also derive a portion of our net revenue from licensing the right to use our intellectual property. We recognize licensing revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. These criteria are usually met at the time our technology is made available to the customer. |
|
| On occasion, we derive revenue from the license of our internally developed intellectual property ("IP"). IP licensing agreements that we enter into generally provide licensees the right to incorporate our IP components in their products with terms and conditions that vary by licensee. Our license fee arrangements generally include multiple deliverables and we are required to determine whether there is more than one unit of accounting. To the extent that the deliverables are separable into multiple units of accounting, we allocate the total fee on such arrangements to the individual units of accounting using management’s best estimate of selling price ("ESP"), if third party evidence ("TPE") or vendor specific objective evidence ("VSOE") does not exist. We defer revenue recognition for consideration that is contingent upon future performance or other contractual terms. |
|
| The Company’s process for determining its ESP for deliverables without VSOE or TPE considers multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. The key factors considered by the Company in developing the ESPs include the nature and complexity of the licensed technologies, our cost to provide the deliverables, the availability of substitute technologies in the marketplace and the Company’s historical pricing practices. We then recognize revenue for each unit of accounting depending on the nature of the deliverable(s) comprising the unit of accounting in accordance with the revenue recognition criteria mentioned above. Fees under these agreements generally include (a) license fees relating to our IP, (b) engineering services, and (c) support services. Historically, each of these elements has standalone value and therefore each are treated as separate units of accounting. Any future licensing arrangements will be analyzed based on the specific facts and circumstances which may be different than our historical licensing arrangements. |
|
| For deliverables related to licenses of our technology that involve significant engineering services, we recognize revenue in accordance with the provisions of the proportional performance method. We determine costs associated with engineering services using actual labor dollars incurred and estimated other direct or incremental costs allocated based on the percentage of time the engineer(s) spent on the project. These costs are deferred until revenue recognition criteria have been met, at which time they are reclassified as cost of revenue. |
|
| We defer revenue when payments are received from customers in advance of revenue recognition. Deferred revenue, consisting principally of license fees collected in advance, at February 1, 2014 and February 2, 2013 was $3.0 million and $3.1 million, respectively, and is included in accrued liabilities in the accompanying consolidated balance sheets. |
|
| On September 27, 2013, we entered into an agreement to license specified IP block and other related technology to a customer to be used in chip designs for a fee of approximately $8.8 million. In addition, we agreed to provide technical support services to resolve difficulties and to answer inquiries in using the licensed technology. Pursuant to this agreement, the customer is obligated to make payments upon the attainment and acceptance of significant milestones, as set forth in the agreement. During fiscal 2014, the first four milestones were met, delivered and accepted by the customer resulting in $7.0 million of revenue recognition. Total additional milestone payments under the agreement are approximately $2.0 million. |
| Cost of Sales, Policy [Policy Text Block] | ' |
| Cost of revenue: Cost of revenue is comprised of the cost of our media processors and chipset solutions, which consists of the cost of purchasing finished silicon wafers manufactured by independent foundries, costs associated with our purchase of assembly, test and quality assurance services and packaging materials, as well as royalties paid to vendors for use of their technology. Also included in cost of revenue is the amortization of purchased IP, manufacturing overhead, including costs of personnel and equipment associated with manufacturing support, product warranty costs, provisions for excess and obsolete inventory, and stock-based compensation expense for personnel engaged in manufacturing support. |
| Foreign Currency Transactions and Translations Policy [Policy Text Block] | ' |
| Foreign currency: The functional currency of our foreign subsidiaries is either the U.S. dollar or the local currency of each country. Where the local currency is the functional currency, currency translation adjustments from the translation of the financial statements of the foreign subsidiaries are included in shareholders’ equity. Foreign currency transaction gains and losses, which are included in interest and other income, net, in the accompanying consolidated statements of operations were a net loss of approximately $0.2 million in fiscal 2014, a net gain of approximately $0.8 million in fiscal 2013 and a net loss of approximately $0.6 million in fiscal 2012. |
| Concentration Risk, Credit Risk, Policy [Policy Text Block] | ' |
| Concentration of credit risk: Financial instruments which potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, short-term and long-term marketable securities, restricted cash, long-term investments and accounts receivable. Our cash, cash equivalents, short-term and long-term marketable securities and restricted cash are on deposit with major financial institutions. Such deposits may be in excess of insured limits. We believe that the financial institutions that hold our cash, cash equivalents, short-term and long-term marketable securities and restricted cash are financially sound and, accordingly, minimal credit risk exists with respect to these balances. We have not experienced any investment losses due to institutional failure or bankruptcy. We perform ongoing credit evaluations of our customers and generally do not require collateral for sales on credit. We review our accounts receivable balances to determine if any receivables will potentially be uncollectible and include any amounts that are determined to be uncollectible in our allowance for doubtful accounts. |
| Commitments and Contingencies, Policy [Policy Text Block] | ' |
| Provisions: In determining loss contingencies, we consider the likelihood of a loss of an asset or the incurrence of a liability as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss from a loss contingency is accrued and charged to expense when the information available indicates that it is probable that an asset has been impaired or a liability has been incurred, and when the amount of the loss can be reasonably estimated. |
| Income Tax, Policy [Policy Text Block] | ' |
| Income taxes: Income taxes are accounted for under an asset and liability approach. Deferred income taxes reflect the net tax effects of any temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts reported for income tax purposes, and any operating losses and tax credit carry-forwards. Deferred tax liabilities are recognized for future taxable amounts and deferred tax assets are recognized for future deductions, net of any valuation allowance, to reduce deferred tax assets to amounts that are considered more likely than not to be realized. |
|
| The impact of an uncertain income tax position on the income tax return must be recognized as the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. |
| Compensation Related Costs, Policy [Policy Text Block] | ' |
| Stock-based compensation: We measure and recognize compensation expense for all stock-based payment awards made to employees and directors based on their estimated fair values measured on the date of grant. Stock option awards are measured using the Black-Scholes option pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service period in our consolidated statements of operations. We estimate forfeitures, based on historical experience, at the time of grant and revise our estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates. |
| Research and Development Expense, Policy [Policy Text Block] | ' |
| Research and development costs: Costs incurred in the research and development of our products are expensed as incurred. |
| Advertising Costs, Policy [Policy Text Block] | ' |
| Advertising costs: Advertising costs are expensed as incurred and are included as an element of sales and marketing expense in the accompanying consolidated statements of operations. Advertising expenses incurred were less than $0.1 million in fiscal 2014, 2013 and 2012, respectively. |
| Comprehensive Income, Policy [Policy Text Block] | ' |
| Comprehensive income (loss): Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes certain changes in equity that are excluded from results of operations. Specifically, foreign currency translation adjustments and unrealized gains or losses on marketable securities. |
| New Accounting Pronouncements, Policy [Policy Text Block] | ' |
| Recent accounting pronouncements: Recent accounting pronouncements expected to impact our operations that are not yet effective are summarized as follows: |
|
| In July 2013, the FASB issued Accounting Standard Update 2013-11 amending Income Taxes: Presentation of an Unrecognized Tax benefit When Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exist that will require the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendment will be effective for interim and annual periods beginning after December 15, 2013; however, early adoption and retrospective application are permitted. We do not expect the adoption of these amendments to have a significant impact on our consolidated financial statements. |
