Hanover Bank v. Commissioner of Internal Revenue…
“ The issuer may then call the bonds at the general price and, following redemption, may refinance the obligation at the lower, prevailing rate of interest.

Bond indentures normally require the issuer to protect the underlying security of the bonds by maintaining the mortgaged property and by insuring that its value is not impaired. ”
