The following table shows the total compensation expensed for share-based compensation plans, including stock options and share grants, recognized in the statements of operations (in thousands):

	2014		2013		2014		2013
Cost of goods sold	$	114	$	136	$	317	$	385

Total share-based compensation expense	$	3,738	$	3,492	$	10,327	$	10,053

Stock Options. Stock options generally vest in equal annual installments over a four-year period and expire eight years after the grant date, and expense was estimated on the date of grant using the Black-Scholes-Merton option pricing model.

The total net cash proceeds received from stock option exercises during the nine months ended September 30, 2014 was approximately $6 million. Stock option expense was approximately $1 million for both the three months ended September 30, 2014 and 2013, and $3 million for both the nine months ended September 30, 2014 and 2013.

A summary of the stock option grants is as follows:

Stock Options	Shares (000)			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (yrs)		Aggregate Intrinsic Value ($000)
Outstanding at January 1, 2014		3,126		$	18.93		4	$	17,461
Granted		176			27.92
Exercised		(548	)		10.19				9,689
Forfeited or expired		(2	)		29.21
Outstanding at September 30, 2014		2,752		$	21.24		4	$	10,772
Exercisable at September 30, 2014		2,221		$	20.46		3	$	10,012

The aggregate intrinsic value in the table above is before applicable income taxes and represents the amount option holders would have received if all options had been exercised on the last business day of the period indicated, based on the Company’s closing stock price.

As of September 30, 2014, total unrecognized share-based compensation expense related to unvested stock options, net of forfeitures, was approximately $6 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 3 years.

Share Grants. Restricted stock awards and restricted stock units generally vest in equal annual installments over a four-year period.

Share grant expense for the three months ended September 30, 2014 and 2013 was approximately $3 million and $2 million, respectively, and approximately $8 million for both the nine months ended September 30, 2014 and 2013.
