STOCKHOLDERS’ RIGHTS PLAN
14. STOCKHOLDERS’ RIGHTS PLAN
 
On August 28, 2014, the Company adopted a stockholders’ rights plan whereby the Board of Directors authorized and declared a dividend distribution of one right for each outstanding share of common stock of the Company to the stockholders of record at the close of business on September 9, 2014. The rights are not presently exercisable and remain attached to the shares of common stock until the occurrence of certain triggering events. The rights will expire on August 28, 2015, unless exercised, redeemed, or exchanged prior to that time. The Board of Directors may terminate the rights plan before the expiration date. In connection with the 13D filings, the Company incurred $2.6 million in legal expenses in 2014.
