APACHE CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The Company recognizes over the requisite service period the fair value cost determined at the grant date based on numerous assumptions, including an estimate of the likelihood that Apache’s stock price will achieve these thresholds and the expected forfeiture rate.
If a price target is not met before the end of the stated achievement period, any unamortized expense must be immediately recognized.
Since the $162 interim price target of the 2008 Share Appreciation Program was not met prior to the stated achievement period, on December 31, 2010, Apache recognized $27 million of unamortized expense and $14 million of unamortized capital costs.
The Company will recognize total expense and capitalized costs for the 2008 Share Appreciation Program of approximately $188 million through 2014.
As of March 2011, the Company had recognized $79 million of total expense and capitalized costs for the 2005 Share Appreciation Program and had no unamortized costs remaining.
A summary of the amounts recognized as expense and capitalized costs for each plan are detailed in the table below:
