Q. I have been contributing to the voluntary contributions program for many years. I understand that when I retire, I can move the interest earnings into my Thrift Savings Plan account and then the principal can be taken out as either a cash payment or an annuity. However, I was informed that the cash payment or annuity is an either/or option and that I can’t designate 50 percent for an annuity and 50 percent for a cash payment. Is this correct? A. Yes.
