Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Goodwill and Intangible Assets, Policy | We review our goodwill and other intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable, and at least annually in accordance with Accounting Standards Codification, ("ASC") No. 350, “Intangibles — Goodwill and Other”. The values assigned to goodwill and intangible assets are normally based on estimates and judgments regarding expectations for the success and life cycle of products and technologies acquired. A severe decline in expectations could result in significant impairment charges, which could have a material adverse effect on our financial condition and results of operations.
Earnings Per Share, Policy | Basic net income per share is calculated by dividing net income by the weighted average number of common shares outstanding for the applicable period. Diluted net income per share is calculated after adjusting the denominator of the basic net income per share calculation for the effect of all potentially dilutive stock compensation awards outstanding during the period.
Segment Reporting, Policy | The accounting policies of the segments are the same as those described in the summary of significant accounting policies in our Form 10-K for the fiscal year ended April 28, 2012. We allocate resources to segments based on operating income. Transfers between segments are recorded using internal transfer prices set by us.
Commitments and Contingencies, Policy | We consider insurance coverage and third-party indemnification when determining required accruals for pending litigation and claims.
