On June 30, 2016, we announced receipt of a letter from a plaintiff’s firm pertaining to certain specific wording in the 2016 Proxy document concerning specific statements in our 2015 Omnibus Incentive Plan regarding the annual per person share limitation on award grants. We provided additional information to such firm and no legal action was initiated. Accordingly, we consider the matter closed.
