Shareholders’ Equity</b> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     At March 31, 2010, Cooper Industries plc had 167,526,217 common shares, $.01 par value issued and outstanding compared to 167,316,595 common shares, $.01 par value at December 31, 2009. During the first quarter of 2010, Cooper issued 841,322 common shares primarily in connection with employee incentive and benefit plans and Cooper’s dividend reinvestment program. During the first quarter of 2010, Cooper Industries plc purchased 631,700 shares of treasury stock at an average price of $42.92 per share. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     On February 12, 2008, Cooper’s Board of Directors authorized the purchase of ten million shares of common stock. On February 9, 2009, Cooper’s Board of Directors increased the share repurchase authorization by ten million shares. Cooper’s Board has also authorized the repurchase of shares issued from time to time under its equity compensation plans, matched savings plan and dividend reinvestment plan in order to offset the dilution that results from issuing shares under these plans. For 2010, Cooper’s current estimate is that 2.5 million shares would be issued under equity compensation plans. During the first quarter of 2010, Cooper had repurchased 631,700 shares under these Board of Directors authorizations. Cooper may continue to repurchase shares under these authorizations from time to time during 2010. The decision whether to do so will be dependent on the favorability of market conditions, as well as potential cash requirements for acquisitions and debt repayments. As of March 31, 2010, 14,340,335 shares remain available to be repurchased under the authorizations by the Board of Directors. </div> </div>  <!-- Begin Block Tagged Note false false false Disclosures related to accounts comprising shareholders' equity, including other comprehensive income.
