SIGNIFICANT ACCOUNTING POLICIES

1. SIGNIFICANT ACCOUNTING POLICIES

Interim Financial Information - The accompanying condensed consolidated financial statements of Micrel, Incorporated and its wholly-owned subsidiaries (together “Micrel” or the “Company”) as of March 31, 2012 and for the three months ended March 31, 2012 and 2011 are unaudited. In the opinion of management, the condensed consolidated financial statements include all adjustments (consisting only of normal recurring accruals) that management considers necessary for a fair statement of its financial position, operating results, comprehensive income and cash flows for the interim periods presented. Operating results and cash flows for interim periods are not necessarily indicative of results for the entire year. The Condensed Consolidated Balance Sheet as of December 31, 2011, was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted (“GAAP”) in the United States of America. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011. These financial statements should also be read in conjunction with the Company’s critical accounting policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2011 and those included in this Form 10-Q below.

Reclassifications — Certain prior period balances have been reclassified to conform to the current period presentation in the Company’s condensed consolidated Financial Statements and the accompanying notes. Such reclassifications had no effect on previously reported results of operations or retained earnings.

Net Income Per Common and Equivalent Share - Basic net income per share is computed by dividing net income by the number of weighted-average common shares outstanding. Diluted net income per share reflects potential dilution from outstanding stock options using the treasury stock method. Reconciliation of weighted-average shares used in computing net income per share is as follows (in thousands):

	Three Months Ended March 31,
	2012		2011
Weighted average common shares outstanding		60,855		61,845
Dilutive effect of stock options outstanding using the treasury stock method		784		1,233
Shares used in computing diluted net income per share		61,639		63,078

For the three months ended March 31, 2012 and 2011, 4.1 million and 2.0 million stock options, respectively, have been excluded from the weighted-average number of common shares outstanding for the diluted net income per share computations as they were anti-dilutive.
