Stock-Based Compensation

9 Months Ended

Jun. 30, 2017

Stock awards generally entitle holders to the right to sell the underlying shares of the Company’s common stock once the awards vest. Stock unit awards generally entitle holders to receive the underlying shares of common stock once the awards vest. Awards generally vest based on the passage of time or the achievement of predetermined Company financial performance goals. In the event a performance measure is not achieved at or above a specified threshold level, the portion of the award tied to such performance measure is forfeited.

Stock and stock unit award activity was as follows:
