Context
This was a tax-withholding/share surrender to cover tax on vested equity — a routine administrative disposition rather than an open-market sale or a purchase. Such withholdings do not necessarily indicate a change in insider sentiment about the company’s prospects. The underlying units are LTIP/partnership units that may convert to partnership OP Units and be redeemed for cash or HASI shares under the partnership and plan terms.
