Stockholders’ Equity

Share Repurchase Program

The Company is authorized to repurchase issued and outstanding shares of its common stock under a share repurchase program approved by the Company's Board of Directors. Share repurchases may be made through open market purchases, privately negotiated transactions or otherwise, at times and in such amounts as management deems appropriate. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements and other market conditions. The repurchase program may be discontinued or suspended at any time and will be funded using available cash. The Company's Board of Directors reviews the share repurchase program from time to time, the last such review having occurred in May 2016. The Company did not repurchase shares under this program during the nine months ended June 30, 2018 or 2017. As of June 30, 2018, the Company may repurchase an additional $10.1 million in shares under this program.

2006 Omnibus Long-Term Incentive Plan (the 2006 Plan)

Under the 2006 Omnibus Long-Term Incentive Plan, or the 2006 Plan, as amended, 13,000,000 shares of common stock were available for issuance as of September 30, 2016. On February 23, 2017, at the Company's annual meeting of stockholders, the stockholders approved amendments to the 2006 Plan to increase the number of shares available for issuance under the 2006 Plan by 3,300,000, to a total of 16,300,000 shares. The 2006 Plan has a fungible share pool so that awards other than options or stock appreciation rights granted would be counted as 1.5 shares from the shares reserved for issuance.

The maximum number of shares subject to options or stock appreciation rights that can be awarded under the 2006 Plan to any person is 1,000,000 per year. The maximum number of shares that can be awarded under the 2006 Plan to any person, other than pursuant to an option or stock appreciation right, is 700,000 per year. The Company issues stock appreciation rights with restrictions that lapse upon either the passage of time (service vesting), achievement of performance targets (performance vesting), or some combination of these conditions. For those stock appreciation rights with only service vesting conditions, the Company recognizes compensation cost on a straight-line basis over the explicit service period. For awards subject to both performance and service vesting conditions, the Company starts recognizing compensation cost over the remaining service period, when it is probable the performance vesting condition will be met. The stock appreciation rights that include only service vesting conditions generally vest over a period of one to four years conditioned on continued employment for the incentive period.

Cash-Settled Stock Appreciation Rights

During the nine months ended June 30, 2018, the Company did not issue any cash-settled stock appreciation rights. During the nine months ended June 30, 2018, 87,084 cash-settled stock appreciation rights were exercised, and 358,660 cash-settled stock appreciation rights were forfeited. As of June 30, 2018, 1,007,889 cash-settled stock appreciation rights were outstanding. During fiscal year 2017, the Company issued 218,550 cash-settled stock appreciation rights at the price of $10.30, and 234,313 cash-settled stock appreciation rights were forfeited. Cash-settled stock appreciation rights are recorded as liability awards.

The intrinsic value and weighted average remaining contractual life in years of outstanding and exercisable options at June 30, 2018 is approximately $1.1 million and 6.12 years, and $0.06 million and 5.2 years, respectively, based on a stock price per share of $6.55 on June 30, 2018.

Upon adoption of ASU 2016-09, beginning in the first quarter of fiscal 2018, the Company recognizes forfeitures of share-based awards as they occur in the period of forfeiture rather than estimating the number of awards expected to be forfeited at the grant date and subsequently adjusting the estimate when awards are actually forfeited.
