Are any of the terms relevant in 2016?  We all have two sets of books - the classic example is depreciation schedules that don't reflect cash value.  Are these terms just types of books for types of perspectives?  Can anyone think of an assets that couldn't be sold in a week in 2016 - if you really tried?

Net Present Value (+ other capital budgeting methods and their risk distributions) in my opinion is the only metrics that matters.  Liquidity and solvency is a matter of perspective; important thumbscrews to lenders I suppose.
