Sure, I know what the accounting says. I just don't know what it means.
If I own stock in Microsoft, it means I own a percentage of all its assets (real estate, intangibles, etc), along with a right to a percentage of its revenue streams. Plus I run the risk of my asset being worthless if Microsoft fails. So I know what that means.
Similarly, if I own Microsoft bonds, it means I have a right to a fixed revenue stream from it, and further, can claim a proportion of its assets if it stops paying me. So I can be said to 'own' a proportion of its assets, insofar as I have certain rights over them. And again, I run the (smaller) risk of my asset being worthless if Microsoft fails.
If I have lent Bob money on a non-recourse basis to buy a house, it's a similar story: I have the right to a fixed revenue stream from Bob, and can claim his asset if he stops paying me. So again, I can be said to own a proportion of the house, less whatever I'd pay him if I seized it. And again, I run the risk of the house burning down, etc etc.
In all three of these examples, my balance sheet asset refers to something real.
But if I've lent Bob money on a full-recourse basis, what is the asset? Not the house -- we've established that. Not the cash -- the cash is gone. So what is the debt instrument in my balance sheet based on?
