For purposes of abatement, a general gift charged on any specific property or fund is a specific gift to the extent of the value of the property on which it is charged, and upon the failure or insufficiency of the property on which it is charged, a general gift to the extent of the failure or insufficiency. Abatement within each classification is in proportion to the amounts of property that each of the beneficiaries would have received if full distribution of the property had been made in accordance with the terms of the trust instrument.
