5.       Stock-Based Compensation

We account for share-based awards in accordance with ASC Topic 718, Compensation – Stock Compensation (“ASC 718”). ASC 718 requires that the cost resulting from all share-based payment transactions be recognized in the financial statements. ASC 718 requires all entities to apply a fair value-based measurement method in accounting for share-based payment transactions with employees except for equity instruments held by employee share ownership plans.

Total compensation expense recognized related to stock-based compensation was $2.5 million and $2.7 million for the three months ended September 30, 2014 and 2013, respectively. For the nine months ended September 30, 2014 and 2013, we recognized stock-based compensation expense of $7.7 million and $6.7 million, respectively. As of September 30, 2014, total unrecognized stock-based compensation expense was $14.3 million, with a weighted average period over which the remaining unrecognized compensation expense is expected to be recorded of approximately 1.8 years.
