Item 2.02. Results of Operations and Financial Condition.

On October 29, 2015, we issued a press release announcing our financial results for the first quarter ended September 30, 2015. A copy of the press release is attached hereto as Exhibit 99.1 and incorporated herein in its entirety by this reference.

We are furnishing the information contained in this Item 2.02 (including Exhibit 99.1). It shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended.

Item 8.01. Other Events. 

On October 29, 2015, we announced that our board of directors (the “Board”) authorized the purchase of up to 500,000 additional shares of common stock under our existing stock repurchase program. The stock repurchase program was originally authorized by the Board in March 1999 and was subsequently amended in September 2004 and April 2013. This most recent increase brings the aggregate number of shares authorized for repurchase under the program from 4,000,000 to 4,500,000 shares.           

Since inception of the stock repurchase program, we have repurchased an aggregate of 3,520,236 shares of common stock, leaving a remaining balance of up to 979,764 shares authorized for purchase under the current program, as increased.           

Purchases may be made from time to time in the open market or in privately negotiated transactions and block trades, in accordance with federal securities laws, including Rule 10b-18 promulgated under the Securities Exchange Act of 1934, as amended. This program does not have an expiration date. The share repurchase program may be modified, terminated or expanded by us at any time without prior notice. There is no guarantee as to the exact number of shares, if any, that will be purchased by us. The amount and timing of any purchases will depend on a number of factors, including price, trading volume, general market conditions, legal requirements, and other factors.
