Jung, Inc., owns a patent for which it paid $66 million. At the end of 2011, it had accumulated amortization on the patent of $16 million. Due to adverse economic conditions, Jung's management determined that it should assess whether an impairment should be recognized for the patent. The estimated undiscounted future cash flows to be provided by the patent total $43 million, and the patent's fair value at that point is $35 million. Under these circumstances, Lester would record

A. a $31 million impairment loss on the patent.

B. a $15 million impairment loss on the patent.

C. no impairment loss on the patent.

D. a $7 million impairment loss on the patent.
