OT - bank loans <<. Bank loans are not "marketable" in the commonly accepted use of that word, so how is one to determine their "market value"? >>
Many bank loans in fact do trade reasonably actively and you can get quotes or at least historic prices on a Bloomberg terminal or via other sources. In fact -- and this is way off topic -- this has created a tax problem because if a loan is materially modified and it treated as "publicly traded" and has been trading below face, the borrower has cancellation of indebtedness income. The recent stimulus bill has a temporary fix for this problem -- my point is, it is enough of a problem to require legislation.
