Choice "A" is correct. Post-August 10, 1993, acquisitions of goodwill, covenants not-to-compete, franchises, trademarks, and trade names must be amortized on a straight-line basis over a fifteen-year period (180 months) beginning with the month of acquisition. So, both the $50,000 acquisition of the goodwill and the $13,000 acquisition of the covenant not-to-compete – for a total cost of $63,000 -- are amortized over the fifteen-year period statutory cost recovery period.Choices "d", "b", and "c" are incorrect per the above rule.
