Stock-Based Compensation

Note 10—Stock-Based Compensation

In May 2009, the Company adopted the 2009 Stock Purchase and Option Plan (the “2009 Option Plan”) for Key Employees of the Company and its subsidiaries.  The Company currently also maintains the 2000 Stock Purchase and Option Plan (the “2000 Option Plan”).  The 2009 Option Plan authorizes the granting of additional stock options by a committee of the Company’s Board of Directors, although no additional options can be granted under the 2000 Option Plan. As of June 30, 2011, there were 7,624,150 shares of common stock available for the granting of additional stock options under the 2009 Option Plan. Options granted under the 2000 Option Plan and the 2009 Option Plan vest ratably over a period of five years and are exercisable over a period of ten years from the date of grant.

In 2004, the Company adopted the 2004 Stock Option Plan for Directors of Amphenol Corporation (the “Directors Option Plan”). The Directors Option Plan is administered by the Company’s Board of Directors.  As of June 30, 2011, the maximum number of shares of common stock available for the granting of additional stock options under the Directors Option Plan was 80,000.  Options granted under the Directors Option Plan vest ratably over a period of three years and are exercisable over a period of ten years from the date of grant.

The grant-date fair value of each option grant under the 2000 Option Plan, the 2009 Option Plan and the Directors Option Plan is estimated using the Black-Scholes option pricing model. The fair value is then amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected share price volatility was calculated based on the historical volatility of the stock of the Company and implied volatility derived from related exchange traded options. The average expected life was based on the contractual term of the option and expected employee exercise and historical post-vesting employment termination experience. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The expected annual dividend per share is based on the Company’s dividend rate.

Stock-based compensation expense includes the estimated effects of forfeitures, which are adjusted over the requisite service period to the extent actual forfeitures differ or are expected to differ from such estimates.  Changes in estimated forfeitures are recognized in the period of change and impact the amount of expense to be recognized in future periods.  For the three months ended June 30, 2011, the Company’s income before income taxes and net income were reduced for stock-based compensation expense by $7,061 and $5,116, respectively, and these reductions were $13,381 and $9,611, respectively, for the six months ended June 30, 2011.  For the three months ended June 30, 2010, the Company’s income before income taxes and net income were reduced for stock-based compensation expense by $6,172 and $4,857, respectively, and these reductions were $11,615 and $8,897, respectively, for the six months ended June 30, 2010. The expense incurred for stock-based compensation is included in selling, general and administrative expense in the accompanying Condensed Consolidated Statements of Income.
