The bonds will be issued to a designated custodian for Roth individual retirement accounts established under Treasury's program. This new savings bond is only available to participants in the retirement savings program and will protect the principal contributed while earning interest at a rate previously available only to federal employees invested in the Government Securities Investment Fund (G Fund) of their Thrift Savings Plan."
