FCFF - amortization of bond discount/premium

Hey guys quick q – schweser says you add back the amortization of a bond discount to FCFF and subtract the amortization of premium, when calculating FCFF.

Is this from the perspective of a bond issuer, or a company holding an investment in bonds? it seems the wrong way round to me but I’m thinking about it from an investor perspective…can someone help explain this? thanks v much

It’s from the bond issuer perspective http://www.analystforum.com/forums/cfa-forums/cfa-level-ii-forum/91309293
