Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	'
	NOTE 1. ORGANIZATION AND BASIS OF PRESENTATION
	Description of Business— Exar Corporation was incorporated in California in 1971 and reincorporated in Delaware in 1991. Exar Corporation and its subsidiaries (“Exar” or “we”) is a fabless semiconductor company that designs, develops and markets high-performance integrated circuits and system solutions for the Communications, High-End Consumer, Industrial & Embedded Systems, and Networking & Storage markets. Exar's broad product portfolio includes analog, display, LED lighting, mixed-signal, power management, connectivity, data management, and video processing solutions.
	Basis of Presentation and Use of Management Estimates—The accompanying condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements and should be read in conjunction with the financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended March 30, 2014 as filed with the SEC. In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, that we believe are necessary for a fair statement of Exar’s financial position as of June 29, 2014 and our results of operations for the three months ended June 29, 2014 and June 30, 2013, respectively. These condensed consolidated financial statements are not necessarily indicative of the results to be expected for the entire year.
	The financial statements include management’s estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of sales and expenses during the reporting periods. Actual results could differ from those estimates, and material effects on operating results and financial position may result.
	Our fiscal years consist of 52 or 53 weeks. In a 52-week year, each fiscal quarter consists of 13 weeks. Fiscal years 2015 and 2014 both consist of 52 weeks.

	NOTE 2. RECENT ACCOUNTING PRONOUNCEMENTS
	In July 2013, the FASB issued amended standards that provided explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. Under the amended standards, the unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward. These amended standard updates are effective for our interim period beginning after December 15, 2013 and applied prospectively with early adoption permitted. The adoption of this guidance did not have any material impact on our financial position, results of operations or cash flows.
	In May 2014, the FASB issued a new standard, Revenue from Contracts with Customers, to clarify the principles for recognizing revenue to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards (“IFRS”) that would (1) provide a more robust framework for addressing revenue recognition; (2) improve comparability of revenue recognition practice across entities, industries, jurisdictions, and capital markets; and (3) provide more useful information to users of financial statements through improved disclosure requirements. This standard is effective for annual reporting periods beginning after December 15, 2016. Exar is currently evaluating the effect the adoption of this standard will have, if any, on our consolidated financial position, results of operations or cash flows.
	In June 2014, the FASB issued amended standards to provide explicit guidance on the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. Under the amended standards, a performance target that affects vesting and that could be achieved after the requisite service period should be treated as a performance condition and therefore, should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. This standard is effective for annual reporting periods beginning after December 15, 2015. Exar is currently evaluating the effect the adoption of this standard will have, if any, on our consolidated financial position, results of operations or cash flows.

Business Combinations [Abstract]	'
Business Combination Disclosure [Text Block]	'
	NOTE 3.    BUSINESS COMBINATIONS
	We periodically evaluate potential strategic acquisitions to broaden our product offering and build upon our existing library of intellectual property, human capital and engineering talent, in order to expand our capabilities in the areas in which we operate or to acquire complementary businesses.
	We account for each business combination by applying the acquisition method, which requires (1) identifying the acquiree; (2) determining the acquisition date; (3) recognizing and measuring the identifiable assets acquired, the liabilities assumed, and any non-controlling interest we have in the acquiree at their acquisition date fair value; and (4) recognizing and measuring goodwill or a gain from a bargain purchase.
	Assets acquired and liabilities assumed in a business combination that arise from contingencies are recognized at fair value on the acquisition date if fair value can be determined during the measurement period. If fair value cannot be determined, we typically account for the acquired contingencies using existing guidance for a reasonable estimate.
	To establish fair value, we measure the price that would be received for an asset or paid to transfer a liability in an ordinary transaction between market participants. The measurement assumes the highest and best use of the asset by the market participants that would maximize the value of the asset or the group of assets within which the asset would be used at the measurement date, even if the intended use of the asset is different.
	Acquisition related costs, including finder’s fees, advisory, legal, accounting, valuation and other professional or consulting fees are accounted for as expenses in the periods in which the costs are incurred and the services are received, with the exception that the costs to issue debt or equity securities are recognized in accordance with other applicable GAAP.
	Acquisition of Integrated Memory Logic
	On June 3, 2014, we acquired approximately 92% of outstanding shares of  Integrated Memory Logic Limited (“iML”), a leading provider of analog mixed-signal solutions for the flat panel display market. The iML acquisition supports Exar's strategy of building a large scale diversified analog mixed-signal business. iML’s results of operations and estimated fair value of assets acquired and liabilities assumed were included in our condensed consolidated financial statements beginning June 4, 2014.
	Consideration
	In June 2014, we acquired approximately 92% of iML outstanding shares for $206.4 million in cash. We expect to pay an additional $17.9 million in cash in exchange for the remaining approximately 8% of outstanding shares, at which time iML will become a wholly owned subsidiary. When iML becomes a wholly owned subsidiary of Exar, it is anticipated that we will assume iML’s employee then outstanding options, preliminarily valued at approximately $3.3 million, and will be converted into an option to purchase a number of Exar’s common stock. The number of shares of Exar’s common stock, as well as the exercise price of the options will be determined based upon an agreed upon option exchange ratio outlined in the merger agreement by and between IML and Exar’s subsidiary, Image Sub Limited dated April 26, 2014. The option exchange ratio is calculated based upon (i) the ratio of the purchase price per share of iML’s stock and Exar’s stock price, and (ii) for those options denominated in Taiwanese dollars, the then currency exchange rates.
	In accordance with Accounting Standard Codification (“ASC”) 805, Business Combinations, the acquisition of approximately 92% of iML’s outstanding shares was recorded as a purchase business acquisition since iML was considered a business. Under the purchase method of accounting, the fair value of the consideration was allocated to net assets acquired. The fair value of purchased identifiable intangible assets was determined using discounted cash flow models from operating projections prepared by management using an internal rate of return of 16.9%. The excess of the preliminary fair value of consideration paid over the preliminary fair values of net assets acquired and identifiable intangible assets resulted in recognition of goodwill of approximately $14.6 million. Goodwill is primarily from expected synergies resulting from combining the operations of iML with that of Exar and is not deductible for tax purposes.
	The total purchase consideration for iML will be approximately $227.6 million and will be comprised of the following items (in thousands):
	Acquisition of approximately 68.3 million shares of iML at NT$91.00 per share in cash	$	206,411
	Fair value of non-controlling interest shares		17,872
	Fair value of iML employee options to be assumed		3,327
	Total purchase price	$	227,610
	Preliminary Purchase Price Allocation
	The allocation of the total preliminary purchase price to iML’s tangible and identifiable intangible assets and liabilities assumed was based on their estimated fair values at the date of acquisition.
	The preliminary fair value allocated to each of the major classes of tangible and identifiable intangible assets acquired and liabilities assumed in the iML acquisition was as follows (in thousands):
		Amount
	Identifiable tangible assets (liabilities)
	Cash	$	133,752
	Accounts receivable		10,096
	Inventories		3,950
	Other current assets		608
	Property, plant and equipment		480
	Other assets		308
	Accrued expenses		(8,137	)
	Accounts payable		(4,219	)
	Long-term liabilities		(3,595	)
	Total identifiable tangible assets (liabilities), net		133,243
	Identifiable intangible assets		79,760
	Total identifiable assets, net		213,003
	Goodwill		14,607
	Fair value of total consideration transferred	$	227,610
	The following table sets forth the components of identifiable intangible assets acquired in connection with the iML acquisition (in thousands):
		Fair Value
	Developed technologies	$	55,570
	In-process research and development		8,040
	Distributor relationships		5,980
	Customer relationships		9,050
	Trade names		1,120
	Total identifiable intangible assets	$	79,760
	In valuing specific components of the acquisition, that includes deferred taxes and intangibles, required us to make estimates that may be adjusted in the future, if new information is obtained about circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets and liabilities as of that date. Thus, the purchase price allocation is considered preliminary and dependent upon the finalization of the valuation of assets acquired and liabilities assumed, including income tax effects. Final determination of these estimates could result in an adjustment to the preliminary purchase price allocation, with an offsetting adjustment to goodwill.
	Acquisition Related Costs
	Acquisition related costs, or deal costs, relating to iML are included in the merger and acquisition costs and interest expense line on the condensed consolidated statement of operations for the first fiscal quarter of 2015 and were approximately $4.2 million.
	Unaudited Pro Forma Financial Information
	The following unaudited pro forma condensed financial information presents the combined revenue of Exar and iML as if the acquisition had occurred as of March 31, 2014 (in thousands).

	The pro forma financial information includes (1) amortization charges from acquired intangible assets of $2.4 million for the three months ended June 29, 2014 and June 30, 2013, respectively; (2) amortization charges from inventory fair value adjustment of $1.5 million and $2.5 million for the three months ended June 29, 2014 and June 30, 2013, respectively; (3) the estimated stock-based compensation expense related to the stock options assumed of $0.2 million and $0.1 million for the three months ended June 29, 2014 and June 30, 2013, respectively; (4) the elimination of historical intangible assets of $92,000 for the three months ended June 29, 2014 and June 30, 2013, respectively; (5) the elimination of historical stock-based compensation charges recorded by iML of $0.2 million and $0.5 million for the three months ended June 29, 2014 and June 30, 2013, respectively, as a result of the cancellation of all outstanding options on the acquisition date; (6) the elimination of acquisition related costs of $8.2 million for the three months ended June 29, 2014; (7) the elimination of $1.8 million revenue and the related $0.9 million costs released from deferred margin for the three months ended June 29, 2014; (8) the elimination of $2.0 million revenue and the related $0.9 million costs released from the deferred margin for the three months ended June 30, 2013; and (9) the related tax provision of $0.2 million and $0.9 million for the three months ended June 29, 2014 and June 30, 2013, respectively. The unaudited pro forma condensed financial information is not intended to represent or be indicative of the condensed results of operations of Exar that would have been reported had the acquisition been completed as of the beginning of the periods presented, and should not be taken as representative of the future consolidated results of operations of Exar.
	Acquisition of Stretch
	On January 14, 2014, we completed the acquisition of Stretch, Inc. (“Stretch”), a provider of software configurable processors supporting the video surveillance market previously located in Sunnyvale, California. The transaction provides Exar with the technology to deliver an end-to-end high-definition solution for both digital and analog transmission of data from the camera to the DVR or NVR in surveillance applications. Stretch’s results of operations and estimated fair value of assets acquired and liabilities assumed were included in our condensed consolidated financial statements beginning January 14, 2014.
	In accordance with Accounting Standard Codification (“ASC”) 805, Business Combinations, the total consideration paid for Stretch was first allocated to the net tangible liabilities assumed based on the estimated fair values of the assets and liabilities at the acquisition date. The excess of the fair value of the consideration paid over the fair value of Stretch’s net tangible liabilities assumed and identifiable intangible assets acquired resulted in the recognition of goodwill of $0.7 million primarily related to expected synergies to be achieved in connection with the acquisition. The goodwill is deductible over 15 years for tax purposes. The table below shows the allocation of the purchase price to tangible and intangible assets acquired and liabilities assumed (in thousands):
		Amount
	Tangible assets	$	2,937
Intangible assets		7,010
Goodwill		667
Liabilities assumed		(10,604	)
Fair value of total consideration transferred	$	10
Acquisition of Cadeka
On July 5, 2013, we completed the acquisition of substantially all of the assets of Cadeka Technologies (Cayman) Holding Ltd., a privately held company organized under the laws of the Cayman Islands and all the outstanding stock of the subsidiaries of Cadeka, including the equity of its wholly owned subsidiary Cadeka Microcircuits, LLC, a Colorado limited liability company (“Cadeka”). With locations in Loveland, Colorado, Shenzhen and Wuxi, China, Cadeka designs, develops and markets high precision analog integrated circuits for use in industrial and high reliability applications. Cadeka’s results of operations and estimated fair value of assets acquired and liabilities assumed were included in our condensed consolidated financial statements beginning July 5, 2013. The pro forma effects of the portion of the Cadeka operations assumed through the transaction on our results of operations during fiscal 2014 were considered immaterial.
In accordance with ASC 805, Business Combinations, the total consideration paid for Cadeka was first allocated to the net tangible liabilities assumed based on the estimated fair values of the assets and liabilities at the acquisition date. The excess of the fair value of the consideration paid over the fair value of Cadeka’s net tangible liabilities assumed and identifiable intangible assets acquired resulted in the recognition of goodwill of $19.4 million primarily related of expected synergies from combining the operations of Cadeka with that of Exar and the release of deferred tax liabilities. The goodwill is not expected to be tax deductible.
The table below shows the allocation of the purchase price to tangible and intangible assets acquired and liabilities assumed (in thousands):
	Amount
Tangible assets	$	3,286
Intangible assets		20,380
Goodwill		19,387

	NOTE 5.	FAIR VALUE
	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. GAAP describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value as follows:
	Level 1 – Quoted prices in active markets for identical assets or liabilities.
	Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Our cash and investment instruments are classified within Level 1 or Level 2 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 fair value of contingent consideration arising from the acquisitions of Altior Inc. (“Altior”) and Cadeka Microcircuits LLC (“Cadeka”) are classified within Level 3 of the fair value hierarchy since it is based on a probability-based approach that includes significant unobservable inputs.
	There were no transfers between Level 1, Level 2, and Level 3 during the fiscal quarter ended June 29, 2014.
	As of June 29, 2014, we sold all of our short term investments to fund the iML acquisition. The following table summarizes our other investments assets and liabilities as June 29, 2014 (in thousands):

	Our marketable securities include U.S. government and agency securities, state and local government securities, corporate bonds and securities, asset-backed and mortgage-backed securities and certificate of deposit. We classify investments as available-for-sale at the time of purchase and re-evaluate such designation as of each balance sheet date. We amortize premiums and accrete discounts to interest income over the life of the investment. Our available-for-sale securities, which we intend to sell as necessary to meet our liquidity requirements, are classified as cash equivalents if the maturity date is 90 days or less from the date of purchase and as short-term marketable securities if the maturity date is greater than 90 days from the date of purchase. As of June 29, 2014, $26.0 million of short term certificate deposit was used as collateral against our CTBC bridge loan and classified as restricted cash. See Note 9-“Short-term Debt”.
	All marketable securities are reported at fair value based on the estimated or quoted market prices as of each balance sheet date, with unrealized gains or losses, net of tax effect, recorded in the condensed consolidated statements of other comprehensive income except those unrealized losses that are deemed to be other than temporary which are reflected in the impairment charges on investments line item on the condensed consolidated statements of operations.
	We received approximately 93,000 common shares of CounterPath Corporation (“CounterPath”) through the Skypoint dissolution, of which we estimated the fair value using the market value of common shares as determined by trading on the Nasdaq CM market. These securities have been classified to Level 2 as of June 29, 2014 and recorded in the other non-current assets line item on the condensed consolidated balance sheet. We believe the fair value inputs of CounterPath do not meet all of the criteria for Level 1 classification primarily due to the low trading volume of the stock. See Note 7–“Long-term Investments” for the discussion on Skypoint.
	The fair value of contingent consideration was determined based on probability-based approach which includes projected revenues, percentage probability of occurrence and discount rate to present value payments. A significant increase (decrease) in the projected revenue, discount rate or probability of occurrence in isolation could result in a significantly higher (lower) fair value measurement. We calculate the fair value of the contingent consideration on a quarterly basis based on a collaborative effort of our operations and financial accounting groups based on additional information as it becomes available. Any change in the fair value adjustment is recorded in the earnings of that period.
	Realized gains (losses) on the sale of marketable securities are determined by the specific identification method and are reflected in the interest income and other net, line item on the condensed consolidated statements of operations.

Our asset-backed securities are comprised primarily of premium tranches of vehicle loans and credit card receivables, while our mortgage-backed securities are primarily from Federal agencies. We do not own auction rate securities nor do we own securities that are classified as subprime.
Management determines the appropriate classification of cash equivalents or short-term marketable securities at the time of purchase and reevaluates such classification as of each balance sheet date. The investments are adjusted for amortization of premiums and accretion of discounts to maturity and such accretion/amortization, which is immaterial for the period presented, is included in the interest income and other, net line in the condensed statements of operations. Cash equivalents and short-term marketable securities are reported at fair value with the related unrealized gains and losses included in the accumulated other comprehensive losses line in the condensed consolidated balance sheets.
We periodically review our investments in unrealized loss positions for other-than-temporary impairments. This evaluation includes, but is not limited to, significant quantitative and qualitative assessments and estimates regarding credit ratings, collateralized support, the length of time and significance of a security’s loss position, our intent not to sell the security, and whether it is more likely than not that we will not have to sell the security before recovery of its cost basis. For the three months ended June 29, 2014, no investments were identified with other-than-temporary declines in value.

The fair value of contingent consideration was determined based on a probability-based approach which includes projected revenues, percentage probability of occurrence and discount rate to present value payments. A significant increase (decrease) in the projected revenue, discount rate or probability of occurrence in isolation could result in a significantly higher (lower) fair value measurement.
The following table presents quantitative information about the inputs and valuation methodologies used for our fair value measurements classified in Level 3 of the fair value hierarchy as of June 29, 2014.

As of June 29, 2014		$	890
In the first quarter of fiscal 2015, the fair value of the contingent consideration for Altior acquisition increased by $49,000 due to the impact of change in present value of the amount payable due to passage of time. Contingent consideration for Cadeka acquisition decreased by $480,000 due to change in timing of achieving revenue targets and passage of time.

	NOTE 6.	GOODWILL AND INTANGIBLE ASSETS
	Goodwill
	Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. We evaluate goodwill for impairment on an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. We conduct our annual impairment analysis in the fourth quarter of each fiscal year. Impairment of goodwill is tested at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair value of the reporting unit. Estimations and assumptions regarding the number of reporting units, future performances, results of our operations and comparability of our market capitalization and net book value will be used. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered impaired and a second step is performed to measure the amount of impairment loss. Because we have one single operating segment and one chief operating decision maker, our President and Chief Executive Officer (“CEO”), we utilize an entity-wide approach to assess goodwill for impairment. As of June 29, 2014, no events or changes in circumstances suggest that the carrying amount for goodwill may not be recoverable and therefore we did not perform an interim goodwill impairment analysis.
	The changes in the carrying amount of goodwill for first fiscal quarter of 2015 and 2014 were as follows (in thousands):
			29-Jun-14		30-Mar-14
	Beginning balance		$	30,410	$	10,356
	Goodwill additions			14,607		20,054
	Ending balance		$	45,017	$	30,410
	Goodwill additions during the first quarter of fiscal 2015 consisted of $14.6 million residual allocation from the iML acquisition purchase price accounting. The goodwill additions during fiscal 2014 consist of $19.4 million and $0.7 million residual allocation from the Cadeka and Stretch acquisition purchase price accounting, respectively.
	Intangible Assets

	Total		$	156,279		(47,238	)		109,041		76,351		(44,961	)		31,390
	Long-lived assets are amortized on a straight-line basis over their respective estimated useful lives. Existing technology is amortized over two to nine years. Customer relationships are amortized over five to seven years. Distributor relationships are amortized over six to seven years. Patents/core technology is amortized over five to six years. Trade names are amortized over three to six years. We expect the amortization of IPR&D to start in fiscal 2015. We evaluate the remaining useful life of our long-lived assets that are being amortized each reporting period to determine whether events and circumstances warrant a revision to the remaining period of amortization. If the estimate of an intangible asset’s remaining useful life is changed, the remaining carrying amount of the long-lived asset is amortized prospectively over the remaining useful life.
	Long-lived assets are evaluated for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets (or asset group) may not be fully recoverable. Whenever events or changes in circumstances suggest that the carrying amount of long-lived assets may not be recoverable, we estimate the future cash flows expected to be generated by the assets (or asset group) from its use or eventual disposition. If the sum of the expected future cash flows is less than the carrying amount of those assets, we recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets. Significant management judgment is required in the grouping of long-lived assets and forecasts of future operating results that are used in the discounted cash flow method of valuation. If our actual results, or the plans and estimates used in future impairment analyses are lower than the original estimates used to assess the recoverability of these assets, we could incur additional impairment charges.
	As of June 29, 2014, there were no indicators that required us to perform an intangible assets impairment review. Due to the decline in forecasted revenue related to certain acquired intangible assets, we recorded $1.6 million impairment charges in the fourth quarter of fiscal 2014.

	NOTE 7.	LONG-TERM INVESTMENT
	In July 2001, Exar became a Limited Partner in the Skypoint Telecom Fund II (US), LP. (“Skypoint Fund”), a venture capital fund focused on investments in communications infrastructure companies. We accounted for this non-marketable equity investment under the cost method in the other non-current assets in the consolidated balance sheet. The partnership was dissolved and the fund distributed stock of investee companies to Exar during first quarter of fiscal 2015.
	We regularly review and determine whether the investment is other-than-temporarily impaired, in which case the investment is written down to its impaired value.
	As of the dates indicated below, our long-term investment balance, which is included in the “Other non-current assets” line item on the condensed consolidated balance sheets, consisted of the following (in thousands):
			June 29,		March 30,
			2014		2014
	Beginning balance		$	946	$	1,288
	Net distributions			—		(19	)
	Impairment charges			—		(323	)
	Ending balance		$	946	$	946
	The carrying amount of approximately $0.9 million as of June 29, 2014 reflects the net of the capital contributions, capital distributions and cumulative impairment charges. During the term of the fund we have made $4.8 million in capital contributions to Skypoint Fund since we became a limited partner in July 2001. As of June 29, 2014, we do not have any further capital commitments.
	Impairment
	We evaluate our long-term investment for impairment on an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. We conduct our annual impairment analysis in the fourth quarter of each fiscal year by comparing the carrying amount to the fair value of the underlying investments. If the carrying amount exceeds its fair value, long term-investment is considered impaired and a second step is performed to measure the amount of impairment loss. We analyzed the fair value of the remaining underlying investments of Skypoint Fund and as a result, no impairment was recorded during the first quarter of fiscal 2015 and 2014. We recorded approximately $0.3 million impairment charges in the fourth quarter of fiscal 2014.

	Stifel
	On May 27, 2014 (the “Initial Funding Date”), Exar entered into a bridge credit agreement (the “Credit Agreement”) certain lenders party and Stifel Financial Corp., as Administrative Agent. The Credit Agreement provided Exar with a bridge term loan credit facility in an aggregate principal amount of up to $90.0 million (the “Bridge Facility”).
	Interest on loans made under the Bridge Facility accrues, at Exar’s option, at a rate per annum equal to (1) the Base Rate (as defined below) plus (a) during the first 90 days following the Initial Funding Date, 7.5% and (b) thereafter, 8.5% or (2) 1-month LIBOR plus (a) during the first 90 days following the Initial Funding Date, 8.5% and (b) thereafter, 9.5%. The “Base Rate” is equal to, for any day, a rate per annum equal to the highest of (a) the prime rate in effect on such day, (b) the federal funds effective rate in effect on such day plus 0.50%, and (c) 1 month LIBOR plus 1.00%. The Base Rate is subject to a floor of 2.5%, and LIBOR is subject to a floor of 1.5%. The interest rate for June, 2014 was 8.65%.
	Exar had drawn $50.0 million and $15.0 million on May 27, 2014 and May 29, 2014, respectively to fund the acquisition of approximately 92% of iML’s outstanding shares. We repaid $26.0 million of the debt in June 2014 through a loan from CTBC with lower interest rate. As of July, 2014, the Stifel loan has been completely paid off through an intercompany loan from iML. See Note 19 – Subsequent Event”.
	CTBC
	On June 9, 2014 we entered into a Business Loan Agreement with CTBC to provide a loan for $26.0 million to partially pay off the Stifel loan. This loan bears an interest rate of 3.25% and matures on December 9, 2014. Interest payments are due monthly with the entire principal due not later than December 9, 2014.
	All obligations of Exar under the Business Loan Agreement are unconditionally guaranteed by iML through a $26.0 million short-term certificate deposit with the same institution.

	On August 28, 2007, we announced the approval of a share repurchase plan (“2007 SRP”) and authorized the repurchase of up to $100.0 million of our common stock.
	On July 9, 2013, we announced the approval of a share repurchase program under which we were authorized to repurchase an additional $50.0 million of our common stock. The repurchase program does not have a termination date, and may be modified, extended or terminated at any time. We intend to retire all shares repurchased under the stock repurchase plan. The purchase price for the repurchased shares of Exar is reflected as a reduction of common stock and additional paid-in capital. We may continue to repurchase our common stock under the repurchase plan, which would reduce our cash, cash equivalents and/or short-term marketable securities available to fund future operations and to meet other liquidity requirements.
	Stock repurchase activities during first quarter of fiscal 2015 and fiscal 2014 were indicated below (in thousands, except per share amounts):

	Equity Incentive Plans
	We currently have two equity incentive plans, in which shares are available for future issuance, the Exar Corporation 2006 Equity Incentive Plan (the “2006 Plan”) and the Sipex Corporation (“Sipex”) 2006 Equity Incentive Plan (the “Sipex Plan”), the latter of which was assumed in connection with the August 2007 acquisition of Sipex.
	The 2006 Plan authorizes the issuance of stock options, stock appreciation rights, restricted stock, stock bonuses and other forms of awards granted or denominated in common stock or units of common stock, as well as cash bonus awards. Restricted stock units ("RSU”) granted under the 2006 Plan are counted against authorized shares available for future issuance on a basis of two shares for every RSU issued. The 2006 Plan allows for performance-based vesting and partial vesting based upon the level of performance. Grants under the Sipex Plan are only available to former Sipex’s employees or employees of Exar hired after the Sipex acquisition. At our annual meeting on September 15, 2010, our stockholders approved an amendment to the 2006 Plan to increase the aggregate share limit under the 2006 Plan by an additional 5.5 million shares to 8.3 million shares. At June 29, 2014, there were 0.7 million shares available for future grant under all our equity incentive plans.

	The aggregate intrinsic values in the table above represent the total pre-tax intrinsic value, which is based on the closing price of our common stock of $11.08 and $11.71 as of June 29, 2014 and March 30, 2014, respectively. These are the values which would have been received by option holders if all option holders exercised their options on that date.
	In January 2012, we granted 480,000 performance-based stock options to our CEO. The options are scheduled to vest in four equal annual installments at the end of fiscal years 2013 through 2016 if certain predetermined market based financial measures are met. If the financial measures are not met, each installment will be rolled over to the subsequent fiscal year. In January 2014, we granted 140,000 performance-based stock options to our CEO. The options are scheduled to vest at the end of fiscal year 2017 if certain predetermined financial measures are met. We recorded $112,000 and $65,000 of compensation expense for these options in the three months ended June 29, 2014 and June 30, 2013, respectively.

	Vested and expected to vest, June 29, 2014			965,301						1.54	$	10,696
	The aggregate intrinsic value of RSUs represents the closing price per share of our stock at the end of the periods presented, multiplied by the number of unvested RSUs or the number of vested and expected to vest RSUs, as applicable, at the end of each period.
	For RSUs, stock-based compensation expense was calculated based on our stock price on the date of grant, multiplied by the number of RSUs granted. The grant date fair value of RSUs less estimated forfeitures was recognized on a straight-line basis, over the vesting period.
	In March 2012, we granted 300,000 performance-based RSUs (“PRSUs”) to our CEO. The PRSUs are scheduled to start vesting in three equal installments at the end of fiscal year 2013 through 2015 with three year vesting periods if certain predetermined financial measures are met. If the financial measures are not met, each installment will be forfeited at the end of its respective fiscal year. We recorded $734,000 and $52,000 of compensation expense for these awards in the three months ended June 29, 2014 and June 30, 2013, respectively.
	In the first quarter of fiscal 2014, we granted 50,000 PRSUs to certain executives. The PRSUs were scheduled to vest in three equal installments at the end of fiscal year 2014 with a three-year vesting period if certain performance measures are met. We recorded stock compensation recovery of $120,000 in the three month ended June 29, 2014 as a result of partially meeting the performance measurements by the executives and recorded $47,000 of stock compensation expense for these awards in the three months ended June 30, 2013.
	In July 2013, as part of the acquisition of Cadeka, we agreed to pay retention bonus to certain former Cadeka employees and the bonus will be settled in RSUs subject to fulfillment of the service period. We recorded $394,000 of compensation expense for these awards in the three months ended June 29, 2014. The expense is reported in the other non-current obligations line in the condensed consolidated balance sheet as the total amount of bonus is to be settled in variable number of RSUs at the completion of the requisite service period. Such non-cash compensation expense is recorded as part of stock compensation expense in the condensed consolidated statement of operations.
	In August 2013, we announced the Fiscal Year 2014 Management Incentive Program (“2014 Incentive Program”). Under this program, each participant’s award is denominated in stock and subject to achievement of certain financial performance goals and the participant’s annual Management by Objective goals. The expense is reported in the other current liabilities line in the condensed consolidated balance sheet as the total amount of bonus is to be settled in variable number of RSUs at the completion of the requisite service period. Such non-cash compensation expense is recorded as part of stock compensation expense in the condensed consolidated statement of operations. We recorded $5,000 of compensation expense for these awards in the three months ended June 29, 2014.
	In October 2013, we granted 70,000 PRSUs to certain executives. The first 50% of the PRSUs are scheduled to start vesting in three equal installments at the end of fiscal year 2015 with a three-year vesting period if certain performance measures are met. The second 50% of the PRSUs are scheduled to start vesting in three equal installments at the end of fiscal year 2016 with a three-year vesting period if certain performance measures are met. We recorded $178,000 of compensation expense for these awards in the three months ended June 29, 2014.
	In January 2014, we granted 82,500 PRSUs to certain former Stretch employees. The PRSUs are scheduled to start vesting in three equal installments at the end of fiscal year 2015 with a three-year vesting period if certain performance measures are met. We recorded $0 of compensation expense in the three months ended June 29, 2014 related to these PRSUs as the vesting of such PRSUs was not deemed probable.

Valuation Assumptions
We estimate the fair value of stock options on the date of grant using the Black-Scholes option-pricing model. The assumptions used in calculating the fair value of stock-based compensation represent our estimates, but these estimates involve inherent uncertainties and the application of management’s judgment which include the expected term of the stock-based awards, stock price volatility and forfeiture rates. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.
We used the following weighted average assumptions to calculate the fair values of options granted during the fiscal periods presented:
		Three Months Ended
		June 29,			June 30,
		2014			2013
Expected term of options (years)			4.5			4.4

	NOTE 13. NET INCOME (LOSS) PER SHARE
	Basic net income (loss) per share excludes dilution and is computed by dividing net income (loss) attributable to Exar by the weighted average number of common shares outstanding for the applicable period. Diluted earnings per share reflects the potential dilution that would occur if outstanding stock options or warrants to purchase common stock were exercised for common stock, using the treasury stock method, and the common stock underlying outstanding RSUs was issued.

	All outstanding stock options and RSUs are potentially dilutive securities. As of June 29, 2014, all outstanding stock options and RSUs were excluded from the computation of diluted net income per share because they were determined to be anti-dilutive. As of June 30, 2013, stock options and RSUs of 1.0 million were excluded from the computation of diluted net income per share because they were determined to be anti-dilutive.

	NOTE 15.      COMMITMENTS AND CONTINGENCIES
	In 1986, Micro Power Systems Inc. (“MPSI”), a subsidiary that we acquired in June 1994, identified low-level groundwater contamination at its principal manufacturing site. The area and extent of the contamination appear to have been defined. MPSI previously reached an agreement with a prior tenant to share in the cost of ongoing site investigations and the operation of remedial systems to remove subsurface chemicals and well closure activities. In April 2012, the San Francisco Bay Regional Water Quality Control Board (“RWQCB”) approved our application for low-threat closure and rescinded the previous cleanup order. All monitoring well closure activities on the site and adjacent/neighboring sites have been completed. We have finalized and executed access, environmental indemnity and tolling agreements, and deed restriction covenants with the property owner. The required deed restriction has been recorded. We are awaiting final determination from RWQCB.
	Outstanding liabilities for remediation activities were immaterial for all periods presented.
	In early 2012, we received correspondences from the California Department of Toxic Substance Control (“DTSC”) regarding its ongoing investigation of hazardous wastes and hazardous waste constituents at a former regulated treatment facility in San Jose, California. In 1985, MPSI made two separate permitted hazmat deliveries to a licensed and regulated site for treatment. DTSC has requested that former/current property owners and companies, currently in excess of 50, that had hazardous waste treated at the site participate in further site assessment and limited remediation activities. We have entered into various agreements with other named generators, former property owners and DTSC limited to the investigation of the sites’ condition and evaluation, and selection of appropriate remedial measures. The designated environmental consulting firm is moving forward with the agreed preliminary site assessment and periodic status reporting. Given that this matter is in the early stages of investigation and discussions are ongoing, we are unable to ascertain our exposure, if any.
	In a letter dated March 27, 2012, Exar was notified by the Alameda County Water District (“ACWD”) of the recent detection of volatile organic compounds at a site adjacent to a facility that was previously owned and occupied by Sipex. The letter was also addressed to prior and current property owners and tenants (collectively “Property Owners”). ACWD requested that the Property Owners carry out further site investigation activities to determine if the detected compounds are emanating from the site or simply flowing under it. In June 2012, the Property Owners filed with ACWD a report of its investigation/characterization activities and analytical data obtained. Accumulated data suggests that compounds of concern in groundwater appear to be from an offsite source. ACWD is investigating alternative upgradient sites. Given that this investigation is ongoing, we are unable to ascertain our exposure, if any.
	We warrant all custom products and application specific products, including cards and boards, against defects in materials and workmanship for a period of 12 months, and occasionally we may provide an extended warranty from the delivery date. We warrant all of our standard products against defects in materials and workmanship for a period of 90 days from the date of delivery. Reserve requirements are recorded in the period of sale and are based on an assessment of the products sold with warranty, historical warranty costs incurred and customer/product specific circumstances. Our liability is generally limited, at our option, to replacing, repairing, or issuing a credit (if it has been paid for). Our warranty does not cover damage which results from accident, misuse, abuse, improper line voltage, fire, flood, lightning or other damage resulting from modifications, repairs or alterations performed other than by us, or resulting from failure to comply with our written operating and maintenance instructions.
	Warranty expense has historically been immaterial for our products. The warranty liability related to our product sales as of September 29, 2013 of $1.4 million was established for the return of certain older generation data compression products shipped in prior years.
	As of the dates indicated below, our warranty reserve balance, which is included in the “Other current liabilities” line item on the condensed consolidated balance sheets, consisted of the following (in thousands):
		June 29,		March 30,

	In the ordinary course of business, we may provide for indemnification of varying scope and terms to customers, vendors, lessors, business partners, purchasers of assets or subsidiaries, and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of agreements or representations and warranties made by us, services to be provided by us, intellectual property infringement claims made by third parties or, matters related to our conduct of the business. In addition, we have entered into indemnification agreements with our directors and certain of our executive officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or executive officers. We maintain director and officer liability insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and officers, and former directors and officers of acquired companies, in certain circumstances.
	It is not possible to determine the aggregate maximum potential loss under these indemnification agreements due to the unique facts and circumstances involved in each particular agreement and claims. Such indemnification agreements might not be subject to maximum loss clauses. Historically, we have not incurred material costs as a result of obligations under these agreements and we have not accrued any liabilities related to such indemnification obligations in our condensed consolidated financial statements.

We are not a named party to any ongoing lawsuit or formal proceeding that, in the opinion of our management, is likely to have a material adverse effect on our financial position, results of operations or cash flows.
	In fiscal year 2014, two former employees of Exar’s French subsidiary asserted claims against that subsidiary for alleged unfair dismissal in the French Labor Courts. We believe that the former employees were terminated in accordance with the requirements of French law and that the former employees’ claims are not supported by evidence. The matters have been scheduled for hearing on October 10, 2014 and October 22, 2014, respectively. We dispute the claims and we intend to vigorously protect our interests.

	NOTE 17.	INCOME TAXES
	During the three months ended June 29, 2014, we recorded an income tax expense of approximately $0.7million. The income tax expense was primarily related to the allocation of tax expense between continuing operations and other comprehensive income when applying the exception to the ASC 740 intraperiod allocation rule upon liquidation of our available for sale security portfolio. During the three months ended June 30, 2013, we recorded an income tax benefit of approximately $9,000. The income tax benefit was primarily due to income tax benefits in certain non-US operations.
	During the three months ended June 29, 2014, the unrecognized tax benefits increased by $2.7million to $16.9million primarily related to the acquisition of iML. If recognized, $14.2million of these unrecognized tax benefits (net of federal benefit) would be recorded as a reduction of future income tax provision before consideration of changes in valuation allowance.
	Estimated interest and penalties related to the income taxes are classified as a component of the provision for income taxes in the condensed consolidated statement of operations. Accrued interest and penalties consisted of the following as of the dates indicated (in thousands):

	Our major tax jurisdictions are the United States federal and various states, Canada, China, Hong Kong, Taiwan, the Cayman Islands and certain other foreign jurisdictions. The fiscal years 2003 through 2013 remain open and subject to examinations by the appropriate governmental agencies in the United States and over varying periods in certain of our foreign jurisdictions.
	ASU No. 2013-11 – U.S. GAAP previously did not include explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. On a jurisdictional basis, Accounting Standard Update (“ASU”) No. 2013-11 generally requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Exar has properly applied this guidance to its required disclosures. The adoption of this guidance did not have any material impact on our financial position, results of operations or cash flows.
