Context
Tax-withholding on vested restricted stock units is common: the company or broker retains shares to cover the officer’s tax liability. These withholdings are routine administrative actions and are not the same as an opportunistic open-market sale; they generally do not by themselves indicate the insider’s view on the company’s prospects.
