Income Per Common Share

Basic income per common share is computed using the weighted average number of common shares outstanding during the period. Diluted income per common share is computed using the weighted average number of common shares and common equivalent shares outstanding during the period. For the three and nine months ended September 30, 2011 and 2010, no shares were excluded from the computation of diluted weighted average shares outstanding.

During the second quarter of 2011, the entire outstanding principal balance of our convertible debt was converted, with the principal amount paid in cash and the conversion premium paid in shares. The convertible notes met the criteria for determining the effect of the assumed conversion using the treasury stock method of accounting, since we had the ability and the intent to settle the principal amount of the notes in cash. Using the treasury stock method, it was determined that the impact of the assumed conversion for the nine months ended September 30, 2011, had a dilutive effect of 0.8 million common equivalent shares and for the three and nine months ended September 30, 2010, had a diluted effect of 1.0 million and 1.1 million common equivalent shares, respectively. The effect of the assumed converted shares is dependent on the stock price at the time of the conversion. See Note 7 for further details on our debt.

Derivative Financial Instruments

Derivative Financial Instruments

We use derivative financial instruments to minimize the impact of foreign exchange rate changes on earnings and cash flows. In the normal course of business, our operations are exposed to fluctuations in foreign exchange rates. In order to reduce the effect of fluctuating foreign currencies on short-term foreign currency-denominated intercompany transactions and other known foreign currency exposures, we enter into monthly forward contracts. We do not use derivative financial instruments for trading or speculative purposes. Our forward contracts are not expected to subject us to material risks due to exchange rate movements because gains and losses on these contracts are intended to offset exchange gains and losses on the underlying assets and liabilities. The forward contracts are marked-to-market through earnings. We conduct our derivative transactions with highly rated financial institutions in an effort to mitigate any material credit risk.
