6.	Stock-Based Compensation

We account for share-based awards in accordance with ASC 718 which 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 $3.7 million and $3.5 million for the three months ended September 30, 2016 and 2015, respectively. For the nine months ended September 30, 2016 and 2015, we recognized stock-based compensation expense of $11.2 million and $8.6 million, respectively.
