This was definitely “front office”, as in providing the barebones minimum required to provide daily mtm and rudimentary delta and vega exposures. And they were long dated with “local” rate and/or FX options, all bundled with “global” knockout or American early exercise features. So, all-in-all, pretty exotic, even in the relevant historical context. I don’t quite remember how many we had. The number 42 comes to mind, but that may have been the number of PCs employed in the process. So call it a few dozen. It was a messy affair, but much more classic in nature than the newfangled credit derivatives we were also grappling with at the time. And since we were largely (or entirely?) providing hedges to very highly rated structured note issuers, we didn’t worry much about counterparty credit exposure.
