Cost basis considerations

For RSU shares, basis equals the vest-date closing price. For ISO shares (qualifying disposition), basis equals strike plus any ordinary-income component at exercise. For ESPP shares, basis depends on whether the sale is a qualifying or disqualifying disposition. These basis rules materially affect whether a reported gross sale amount is mostly gain or mostly return of basis.
