Context

Sell-to-cover transactions are routine administrative actions that occur when restricted stock units (RSUs) vest and the issuer or broker sells a portion of shares to cover required tax withholding. Such mandated sales generally do not indicate the insider's view on the company's near-term prospects. Purchases by insiders tend to be more informative than routine withholding sales.
