Updates To Critical Accounting Policies And Estimates [Abstract]
Updates To Critical Accounting Policies And Estimates	4. UPDATES TO CRITICAL ACCOUNTING POLICIES AND ESTIMATES Inventories: Our worldwide inventories are stated at the lower of cost or market, generally using a weighted-average cost method. Our inventories included approximately $31.9 million of finished goods and $3.4 million of raw materials and work-in-progress as of December 3, 2011, as compared to approximately $28.0 million of finished goods and $2.9 million of raw materials and work-in-progress as of May 28, 2011. At this time, we do not anticipate any material risks or uncertainties related to possible inventory write-downs for the remainder of our fiscal year ending June 2, 2012. Revenue Recognition: Our product sales are recognized as revenue upon shipment, when title passes to the customer, when delivery has occurred or services have been rendered, and when collectability is reasonably assured. We also record estimated discounts and returns based on our historical experience. Our products are often manufactured to meet the specific design needs of our customers' applications. Our engineers work closely with customers to ensure that our products will meet their needs. Our customers are under no obligation to compensate us for designing the products we sell. In a limited number of cases, we provide and bill our customers with non-product related services, such as testing, calibration, non-recurring engineering, tooling, and installation services. We have concluded that, in the limited cases where remaining obligations exist after delivery of the product, the obligation relative to the unit of accounting is inconsequential or perfunctory. This conclusion was reached based on the following facts: the timing of any remaining obligation is agreed upon with the customer, which in most cases, is performed immediately after the delivery of the product; the cost and time involved to complete the remaining obligation is minimal, and the costs and time do not vary significantly; we have a demonstrated history of completing the remaining obligations timely; and finally, failure to complete the remaining obligation does not enable the customer to receive a full or partial refund of the product or the service. Discontinued Operations: In accordance with Accounting Standards Codification ("ASC") 205-20, Presentation of Financial Statements- Discontinued Operations ("ASC 205-20"), we reported the financial results of RFPD as a discontinued operation. Refer to Note 5 "Discontinued Operations" of our notes to our unaudited consolidated financial statements for additional discussion on the sale of RFPD. Loss Contingencies: We accrue a liability for loss contingencies when it is probable that a liability has been incurred and the amount can be reasonably estimated. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. If we determine that there is at least a reasonable possibility that a loss may have been incurred, we will include a disclosure describing the contingency. New Accounting Pronouncements: During September 2011, the FASB issued Accounting Standards Update (ASU) No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment, ("ASU Update No. 2011-08). ASU Update No. 2011-08 is intended to simplify how entities, both public and nonpublic, test goodwill for impairment. ASU Update No. 2011-08 permits an entity to 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 as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in Topic 350, Intangibles - Goodwill and Other. The more-likely-than-not threshold is defined as having a likelihood of more than 50%. ASU Update No. 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted, including for annual and interim goodwill impairment test performed as of a date before September 15, 2011, if an entity's financial statements for the most recent annual or interim period have not yet been issued or, for nonpublic entities, have not yet been made for issuance. We will be adopting ASU Update No. 2011-08 during our fourth quarter of fiscal 2012 and do not expect the adoption to have a material impact on our financial results. During November 2011, the FASB issued ASU No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities, (ASU Update No. 2011-11). ASU Update No. 2011-11, requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. Offsetting, otherwise known as netting, is the presentation of assets and liabilities as a single net amount in the statement of financial position (balance sheet). An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. We will be adopting ASU Update No. 2011-11during our first quarter of fiscal 2014.
