One person familiar with the matter said large dealers contemplated showing each other all of their credit default swap trades with Lehman. Disclosing their positions may enable dealers to find ways to offset their positions with each other wherever possible. Later in the day, some traders were told that Lehman -- with the help of Federal Reserve officials -- will try to figure out which of its counterparties have CDS trades that can be offset. Those counterparties would be informed of the offsetting positions, following which they can unwind their respective swaps with Lehman and concurrently enter into new swap contracts with each other. For example, if one dealer has bought a swap from Lehman and Lehman sold a similar swap to another bank, the two banks could agree to face each other directly.
