2、-33.Maturity:Years until bondmust be repaid.Declines.4.Issue date:Date when bondwas issued.5.Default risk:Risk that issuer will not make interest or principal payments.4-4How does adding a call provision affect a bond?nIssuer can refund if rates decline.That helps the issuer but hurts the investor.n

3、Therefore,borrowers are willing to pay more,and lenders require more,on callable bonds.nMost bonds have a deferred call and a declining call premium.4-5Whats a sinking fund?nProvision to pay off a loan over its life rather than all at maturity.nSimilar to amortization on a term loan.nReduces risk to
