Practitioner Perspectives
Imerck” (chapter 12), Judy Lewent and John Kearney describe the company’sn “identifying, mea sur ing, and hedging currency risk at
effort to understand and manage the effect of exchange rate volatility on world-
wide revenues and earnings. In a thought pro cess that parallels the one laid out
in preceding chapters (by Smith, Stulz, and others), Merck’s trea sury arrived at
the following conclusions: (1) the home currency value of cash fl ows regularly
repatriated by its many overseas subsidiaries was vulnerable to a strengthening

ability to make long- term investments in research and development and mar-

the lower tail of the distribution (and not to minimize variance), hedging (only
part of ) its currency options was the most cost- effective means of ensuring the
company’s ability to carry out its long- range strategic plan.
In “Corporate Insurance Strategy: The Case of British Petroleum” (chap-
ter 13), Neil Doherty and Clifford Smith describe a radical shift in British Pe-
troleum’s approach to insuring property and casualty losses, product liability
suits, and other insurable events. Conventional corporate practice—and until
recently the long- standing risk management policy of British Petroleum
(BP)—was to insure against large losses while “self- insuring” smaller ones. In
this chapter, Doherty and Smith explain why BP chose to fl out the conven-
tional wisdom and now insures against most smaller losses while self- insuring
larger ones.
The BP decision came down to factors affecting the market supply of in-
surance as well as the corporate demand for it. On the demand side, the au-
thors demonstrate that the primary source of demand for insurance by large
