SUBSEQUENT EVENT
 
On October 27, 2015 our Board of Directors authorized the repurchase of up to $5,000 of our common stock from time to time on the open market, in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, or in privately negotiated transactions pursuant to a newly authorized stock repurchase plan. Repurchases may also be made under a Rule 10b5-1 plan to be entered into with RW Baird & Co, which would permit shares to be repurchased when we might otherwise be precluded from doing so under insider trading laws. The timing and amount of any shares repurchased under the 2015 Repurchase Plan will be determined by our management, based on our evaluation of market conditions and other factors. The 2015 Repurchase Plan does not obligate us to purchase any particular amount of common stock and may be suspended or discontinued at any time without prior notice. The 2015 Repurchase Plan will be funded using our operating cash flow or available cash.
