Financial assets include stocks and bonds. These are fairly simple securities that can often be valued using quoted market prices. However, there are more complex financial instruments that do not have quoted market prices. These complex securities must still be valued on the balance sheet at fair value. Generally accepted accounting principles require that the reporting entity use assumptions in valuing investments when market prices or critical valuation inputs are unobservable.

Question:

What are the etchical considerations in making subjective valuations of these complex financial instruments?
