forfeited stock

基本解释

Borrowers generally didn't report any income until the stock was forfeited or sold. (Some might not have reported income even then, since Derivium didn't send 1099s.) The IRS and California tax authorities assert that the loans were really sales, in part because now inves-tors can't get their stock back.
