Henry Owens, CPA works in a local accounting firm. He is the tax manager on a major client in the office. The firm prepares compiled financial statements for the client on a quarterly basis. The client was impacted by the BP oil spill off the Gulf coast, and the client would like to engage Henry to help the business prepare a claim for damages from BP. The client would like to pay Henry on a contingent fee basis where Henry and his firm would receive 15% of any amounts recovered in a settlement with BP. Henry would receive no fee unless amounts are recovered. Can Henry accept this engagement? Why or why not?
