Suppose a decision maker is considering three decision alternatives: A1, A2, and A3. Three potential states of nature have been identified: S1, S2, and S3. The payoff for each combination of alternative and state of nature has been estimated and appears in the following payoff table:

	S1	S2	S3
A1	113	96	-65
A2	117	62	-52
A3	32	45	40

Calculate the regret (or opportunity loss) value for the combination of A2 and S2.
