Sanchez, Incorporated, is considering an investment of $377,000 in an asset with an economic life of 5 years. The firm estimates that the nominal annual cash revenues and expenses at the end of the first year will be $257,000 and $82,000, respectively. Both revenues and expenses will grow thereafter at the annual inflation rate of 3 percent. The company will use the straight-line method to depreciate its asset to zero over five years. The salvage value of the asset is estimated to be $57,000 in nominal terms at that time. The one-time net working capital investment of $16,000 is required immediately and will be recovered at the end of the project. The tax rate is 22 percent. What is the project’s total nominal cash flow from assets for each year? Note: A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to the nearest whole number, e.g., 32.
