NOTE 16. SHAREHOLDERS’ EQUITY

Share Repurchase Program

Between August 2011 and January 2012, our Board of Directors authorized the repurchase of up to a total of $55.0 million of our common stock. In July 2013, our Board of Directors approved a $12.3 million increase to our existing share repurchase program to a total of $67.3 million. As of March 31, 2015, $37.0 million was available to purchase common stock under our share repurchase program.

Since the share repurchase program began, through March 31, 2015, we have repurchased 1.3 million shares of our common stock at a total cost of $30.3 million, including commission expense. During fiscal 2014, we repurchased 86,000 shares at a total cost of $3.0 million and an average per share cost including commission expense of $34.58. During fiscal 2013 and 2015, we did not repurchase any shares of our common stock. The repurchases are made from time to time on the open market at prevailing market prices or in negotiated transactions off the market. Repurchased shares are retired.

Dividend Payments

During fiscal 2015, our total quarterly dividend payout was $9.0 million and was made from retained earnings. During fiscal 2014, we did not pay dividends on our outstanding common stock. During fiscal 2013, our total dividend payout was $22.0 million and was made from retained earnings. See Note 21, “Summary of Quarterly Data (Unaudited)” for further information on quarterly dividends declared on our common stock during the past two fiscal years.

Common Stock Warrants

At March 31, 2015, there were warrants to purchase 4,000 shares of common stock outstanding at a weighted average exercise price of $3.00 per share, expiring in fiscal years 2016 through 2017. In March 2015, the terms of our agreement with Kansas State University Institute for Commercialization were amended and accordingly, the vesting of these outstanding warrants was accelerated. During the fourth quarter of fiscal 2015, we recorded expense of $0.2 million related to the vesting acceleration using the Black-Scholes option-pricing model.

At March 31, 2014, there were warrants to purchase 30,000 shares of common stock outstanding, of which 20,000 shares were vested, at a weighted average exercise price of $3.00 per share. At March 31, 2013, there were 30,000 warrants outstanding, of which 14,000 shares were vested, to purchase common stock at a weighted average exercise price of $3.00 per share, expiring in fiscal years 2016 through 2017. The fair value of the warrants issued were determined using the Black-Scholes option-pricing model and were amortized over their estimated useful life, of approximately ten years, as an intangible asset. The warrants vested at a rate of 20% annually from their issuance dates and had a term of five years.
