Complete the function file_split in the t07_functions.py module, and complete the testing code for the function in t07.py. file_split reads from an input file and copies the contents of that file into two output files. Lines containing digits are copied to one output file, lines without digits are copied to the second output file, and empty lines are ignored. The sample file source.txt contains: As easy as 123! No numbers here. We're Number 1! Got no digits. 6 of one, 1/2 dozen of another. I am not a number, I am a free man! Got my BFG9000. which is split into two files, the first containing lines with digits: As easy as 123! We're Number 1! 6 of one, 1/2 dozen of another. Got my BFG9000. and the second lines without digits: No numbers here. Got no digits. I am not a number, I am a free man! Complete the testing for file_split in the t07.py module by working with the appropriate files and calling the function. The names of the output files are up to you.

Integrative: Conflicting Rankings The High-Flying Growth Company (HFGC) has been growing very rapidly in recent years, making its shareholders rich in the process. The average annual rate of return on the stock in the last few years has been 20%, and HFGC managers believe that 20% is a reasonable figure for the firm’s cost of capital. To sustain a high growth rate, HFGC’s CEO argues that the company must continue to invest in projects that offer the highest rate of return possible. Two projects are currently under review. The first is an expansion of the firm’s production capacity, and the second involves introducing one of the firm’s existing products into a new market. Cash flows from each project appear in the following table. year, plant expansion, product introduction 0. -3,500,000 -500,000 1 1,500,000 250,000 2. 2,000,000 350,000 3 2,500,000 375,000 4 2,750,000 425,000 A. Calculate the NPV, IRR, and PI for both projects. B. Rank the projects based on their NPVs, IRRs, and PIs. C. Do the rankings in part b agree or not? If not, why not? D. The firm can only afford to undertake one of these investments, and the CEO favors the product introduction because it offers a higher rate of return (that is, a higher IRR) than the plant expansion. What do you think the firm should do? Why?

P11-25 Integrative—Determining relevant cash flows Lombard Company is contemplating the purchase of a new high-speed widget grinder to replace the existing grinder. The existing grinder was purchased 2 years ago at an installed cost of $60,000; it was being depreciated under MACRS using a 5-year recovery period. The existing grinder is expected to have a usable life of 5 more years. The new grinder costs $105,000 and requires $5,000 in installation costs; it has a 5-year usable life and would be depreciated under MACRS using a 5-year recovery period. Lombard can currently sell the existing grinder for $70,000 without incurring any removal or cleanup costs. To support the increased business resulting from purchase of the new grinder, accounts receivable would increase by $40,000, inventories by $30,000, and accounts payable by $58,000. At the end of 5 years, the existing grinder would have a market value of zero; the new grinder would be sold to net $29,000 after removal and cleanup costs and before taxes. The firm is subject a 40% tax rate. The esti- mated earnings before depreciation, interest, and taxes over the 5 years for both the new and the existing grinder are shown in the following table. (Table 4.2 on page 117 contains the applicable MACRS depreciation percentages.) Year Earnings before depreciation, interest, and taxes New grinder Existing grinder $43,000 $26,000 43,000 24,000 43,000 22,000 43,000 20,000 43,000 18,000 a. Calculate the initial investment associated with the replacement of the existing grinder by the new one. b. Determine the incremental operating cash inflows associated with the proposed grinder replacement. (Note: Be sure to consider the depreciation in year 6.) c. Determine the terminal cash flow expected at the end of year 5 from the pro- posed grinder replacement. d. Depict on a time line the relevant cash flows associated with the proposed grinder replacement decision.
