Context

• The March 7 transaction was a settlement/tax-withholding related to a restricted stock award (not an option exercise); the company withheld shares to cover taxes. The March 9 sale was executed under a pre-established Rule 10b5-1 plan to cover tax obligations. Such withholding and 10b5-1 sales are common administrative transactions and are routine — they do not by themselves indicate the insider’s view of the company’s prospects.
