5. A)

The above table contains the bilateral net positions (in million dollars) among three dealers for two types of OTC products: swaps (double arrow) and options (single arrow). The numbers above the diagonal are for swaps, and they represent liabilities, just as how the positions are described on the PPT slides. For instance, from A to C, we have $66 million, which is how much A owes C, or alternatively, how much C is exposed to A. The numbers below the diagonal are defined analogously except that they are for options. Please compute the exposure as laid out in the following table

where cases I, II, III, IV, and V correspond to, respectively, 1) bilateral clearing, 2) central clearing of options, 3) central clearing of forward contracts, 4), central clearing of both forward contracts and options, but at separate clearing houses, and 5) central clearing all contracts at one clearing house. As in the PPT slides, Inc. stands for including the clearing house, and Exc. stands for excluding clearing house (or equivalently, assuming the clearing house is default-free). Note: in IV and V, we no longer consider the case of clearing houses being default-free since the exposure of all dealers is zero in that case.
