Definition for: Treasury Investment Growth Receipts
"Treasury Investment Growth Receipt" or "TIGRs" are a form of bond backed by the federal government. They are "zero coupon" bonds sold at a discount and do not pay periodic interest payments. Interest and principal are paid at maturity. Because they are government bonds TIGRs are considered a very safe investment. The rate of return is low, as compared to other investments, but the risk is also very low.
