A) discount loans are meant to provide temporary liquidity for inherently solvent banks.
B) borrowing is not automatic, that is, banks gain access only on a "need to borrow" basis.

D) discount window advances to undercapitalized banks that eventually fail requires the Federal Reserve to compensate the FDIC for incremental losses caused by keeping the bank open for an additional period of time.
E) All of the above.
