Tanaka Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $397,000 is estimated to result in $145,000 in annual pretax cost savings. The press qualifies for 100 percent bonus depreciation and it will have a salvage value at the end of the project of $46,000. The press also requires an initial investment in spare parts inventory of $15,100, along with an additional $2,100 in inventory for each succeeding year of the project. The shops tax rate is 21 percent and its discount rate is 8 percent. Calculate the project's NPV.

Note: Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.
