Alea comments on Maiden Lane I, so I won't bother. Except to say that it isn't the assets -- look at the whole balance sheet.
Per Maiden Lane III:
ML III LLC borrowed approximately $24.3 billion from the New York Fed in the form of a senior loan (Senior Loan)....
As of October 31, 2008, the Asset Portfolio had a par value of approximately $62.1 billion.
Per Maiden Lane II :
ML II LLC financed this purchase by borrowing $19.5 billion (Senior Loan) from the New York Fed.
As of October 31, 2008, the Asset Portfolio had a par value of approximately $39.3 billion.
These are not great assets. The Fed needs ML III to pay out @ 40% of par and ML III at 50% of par.
The detailed audited year end financials are quite interesting but mostly ramble on about fair value/M2M values. You can see what the assets consist of, but they have a decent chance of paying back the NYFRB with interest.
