The aggregate number of shares that the Company could be obligated to issue upon conversion of its $172,500 Convertible Notes which the Company issued in May 2008, is approximately 4,248,761. It is the Company’s current intent to settle the principal amount of any conversions in cash, and any additional conversion consideration in cash, shares of EnerSys common stock or a combination of cash and shares. During the fourth quarter of fiscal 2013, the average price of our common stock at $41.38 per share exceeded the conversion price of $40.60 per share on the Convertible Notes. 20,022 shares relating to the conversion premium ($41.38-$40.60) on the Convertible Notes were included in the diluted earnings per share using the treasury stock method. No contingent shares were included in diluted shares outstanding during fiscal 2012 and 2011 as the specified conversion price exceeded the average market price of the Company’s common stock, and the inclusion of contingent shares would have been anti-dilutive. See Note 8 for more details on the Convertible Notes and their redemption.
