问题如下：
Which comments about non-deliverable forwards (NDFs) is least accurate?
选项：
A. NDFs are cash settled in the non-controlled
currency of the currency pair.
B. NDFs have greater credit risk associated with
them than outright forward contracts.
C. The pricing of NDFs may differ from what is expected on the basis of
arbitrage conditions.
解释：
B is correct.
考点：Currency Management for Emerging Market Currencies
解析：NDF相比forward信用风险更小，而不是更大。因为NDF是现金结算（cash settlement），不需要结算本金，所以到期时交割的现金流更小，面临的信用风险更小。
