The increase in stock-based compensation expense for the three months ended March 31, 2014 as compared to the same period of 2013 is due primarily to 2.1 million options and 0.7 million shares of restricted stock awards granted to management during the first quarter of 2014, which will generally vest over two to four years.
As of March 31, 2014, there was $61.4 million of total unrecognized compensation cost related to stock-based compensation arrangements for stock options and restricted stock awards. This cost is expected to be recognized over a weighted-average period of 2.9 years.
