SIGNIFICANT ACCOUNTING POLICIES

Interim Financial Information - The accompanying condensed consolidated financial statements of Micrel, Incorporated and its wholly-owned (together “Micrel” or the “Company”) as of March 31, 2013 and for the three months ended March 31, 2013 and 2012 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, 2012, 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, 2012. 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, 2012 and those included in this Form 10-Q below.

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 and restricted stock units. Reconciliation of weighted-average shares used in computing net income per share is as follows (in thousands):

	Three Months Ended
	March 31,
	2013	2012
Weighted average common shares outstanding	58,270	60,855
Dilutive effect of stock options and restricted stock units	760	784
Shares used in computing diluted net income per share	59,030	61,639

For the three months ended March 31, 2013 and 2012, 5.3 million and 4.1 million shares underlying 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.
