sentence

English to German Bus/Financial Accounting

The Company entered into treasury rate locks on $ XXX of five year debt. On November X, 2003, the treasury locks were settled resulting in a gain of $XXX, which will be amortized into interest expense over the term of the debt. **The gain on the treasury locks converts fixed rate cash flows from 6.71% to 6.56 % on $XXX of the new debt.**

Can someone help with the translation, please? Even if you cannot translate it into German an explanation would also be helpful. Concerning the sentence before: why is a gain amortized? Did I miss something here?

Thank you very much.
