Appliance Center is an experienced home appliance dealer. Appliance Center also offers a number of services together with the home appliances that it sells. Assume that Appliance Center sells ovens on a standalone basis. Appliance Center also sells installation services and maintenance services for ovens. However, Appliance Center does not offer installation or maintenance services to customers who buy ovens from other vendors. Pricing for ovens is as follows. Oven only $ 800 Oven with installation service 850 Oven with maintenance services 975 Oven with installation and maintenance services 1,000 In each instance in which maintenance services are provided, the maintenance service is separately priced within the arrangement at $175. Additionally, the incremental amount charged by Appliance Center for installation approximates the amount charged by independent third parties. Ovens are sold subject to a general right of return. If a customer purchases an oven with installation and/or maintenance services, in the event Appliance Center does not complete the service satisfactorily, the customer is only entitled to a refund of the portion of the fee that exceeds $800. Instructions (a) Assume that a customer purchases an oven with both installation and maintenance services for $1,000. Based on its experience, Appliance Center believes that it is probable that the installation of the equipment will be performed satisfactorily to the customer. Assume that the maintenance services are priced separately. Explain whether the conditions for a multiple-deliverable arrangement exist in this situation. (b) Indicate the amount of revenues that should be allocated to the oven, the installation, and to the maintenance contract.

Suppose you asked your favorite AI query tool “How long is the carryover period for NOLs incurred in 2024?” and the AI tool responded as follows:   The carryover period for a net operating loss (NOL) incurred in 2024 would typically be up to 20 years. This means that the corporation or individual with the NOL can carry the loss forward and use it to offset taxable income in future tax years for up to 20 years from the year in which the NOL was generated.   Is the AI answer to the question correct?  Explain.
