Dilutive effect of convertible notes	—		—			103
Dilutive effect of stock-based awards	309		—			507

Convertible Notes

Prior to the repayment/redemption of our convertible notes, which was completed during the third quarter of 2011, we were required to settle the principal amount of the convertible notes in cash and could elect to settle the remaining conversion obligation (stock price in excess of conversion price) in cash, shares, or a combination thereof. During the periods in which the convertible notes were outstanding, we included in the EPS calculation the amount of shares it would have taken to satisfy the conversion obligation, assuming that all of the convertible notes were converted. The average quarterly closing prices of our common stock were used as the basis for determining the dilutive effect on EPS. The quarterly average closing prices of our common stock for the first three fiscal quarters of 2011 did not exceed the conversion price of $65.16 and, therefore, did not have an effect on diluted shares outstanding for the year. During two fiscal quarters in the year ended December 31, 2010, the average closing prices of our common stock exceeded the conversion price of $65.16 and, therefore, 103,000 shares were included in the diluted EPS calculation for that year.

Stock-based Awards

For stock-based awards, the dilutive effect is calculated using the treasury stock method. Under this method, the dilutive effect is computed as if the awards were exercised at the beginning of the period (or at time of issuance, if later) and assumes the related proceeds were used to repurchase common stock at the average market price during the period. Related proceeds include the amount the employee must pay upon exercise, future compensation cost associated with the stock award, and the amount of excess tax benefits, if any. As a result of our net loss for 2011 there was no dilutive effect to the weighted average common shares outstanding for that year. Approximately 1.1 million, 1.3 million, and 456,000 stock-based awards were excluded from the calculation of diluted EPS for the years ended December 31, 2012, 2011, and 2010 respectively, because they were anti-dilutive. These stock-based awards could be dilutive in future periods.

Preferred Stock

We have authorized the issuance of 10 million shares of preferred stock with no par value. In the event of a liquidation, dissolution, or winding up of the affairs of the corporation, whether voluntary or involuntary, the holders of any outstanding preferred stock will be entitled to be paid a preferential amount per share to be determined by the Board of Directors prior to any payment to holders of common stock. There was no preferred stock sold or outstanding at December 31, 2012, 2011, and 2010.
