Key Dates

Recommendation

This Form 4 reports a routine 'sell-to-cover' transaction by the CFO to satisfy tax obligations related to vested restricted stock units, executed under a pre-arranged 10b5-1 plan. Such transactions are not typically indicative of a change in the executive's outlook on the company's prospects and therefore do not warrant a change in investment recommendation based solely on this filing. The CFO still retains a substantial number of shares.
