Riff Hospital recently treated an accident victim in the emergency room. Because the patient was unconscious when he arrived, Riff treated the patient without knowing whether he had insurance or, if he did, whether it was with an insurer with which Riff has a preferred-provideragreement in place. The standard cost for the services Riff provided was $25,000. Riff discounts emergency room services by 70% for patients whose insurers have preferred-provider agreements with Riff. Required: For each of the following independent scenarios, determine the amount of revenue Riff should report and the point in time when revenue may be recognized. 1. When the patient is able to communicate, it is determined the patient has insurance and Riff is one of the insurer's preferred providers. 2. When the patient is able to communicate, it is determined the patient has insurance, but Riff is not one of the insurer's preferred providers. In such cases, insurers will typically claim the hospital's charges are above the usual and customary charge for the services provided and refuse to pay the entire bill. Riff believes there is an 80% chance it will be able to negotiate a 50% discount with the insurer and a 20% chance it will negotiate a 60% discount with the insurer. 3.
