Question

Diamond & Turf Inc. is considering an investment in one of two machines. The sewing machine will increase productivity from sewing 150 baseballs per hour to sewing 290 per hour. The contribution margin per unit is $0.32 per baseball. Assume that any increased production of baseballs can be sold. The second machine is an automatic packing machine for the golf ball line. The packing machine will reduce packing labor cost. The labor cost saved is equivalent to $21 per hour. The sewing machine will cost $260,000, have an eight-year life, and will operate for 1,800 hours per year. The packing machine will cost $85,000, have an eight-year life, and will operate for 1,400 hours per year. Diamond & Turf seeks a minimum rate of return of 15% on its investments.

a. Determine the net present value for the two machines. Use the table of present values of an annuity of $1 above. Round to the nearest dollar.

b. Determine the present value index for the two machines. Round to two decimal places.

Present Value of an Annuity of $1 at Compound Interest Year 6% 10% 12% 15% 20% 1 0.943 0.909 0.893 0.870 0.833 2 1.833 1.736 1.690 1.626 1.528 3 2.673 2.487 2.402 2.283 2.106 4 3.465 3.170 3.037 2.855 2.589 5 4.212 3.791 3.605 3.353 2.991 6 4.917 4.355 4.111 3.785 3.326 7 5.582 4.868 4.564 4.160 3.605 8 6.210 5.335 4.968 4.487 3.837 9 6.802 5.759 5.328 4.772 4.031 10 7.360 6.145 5.650 5.019 4.192

Explanation / Answer

Diamond & Turf Inc. Calculation of NPV Year PV Annuity Factor   Sewing Machine Packing Machine Amount PV Amount Amount PV Amount Present value of annual net cash flows (A) Increase in Contribution Per Year = $0.32 X 140 Balls X 1800 1-8 4.487          80,640        361,832 Labour Cost Saved = $21 X 1400 1-8 4.487         29,400         131,918 Less amount to be invested (B) Cost OF Machine 0 1        260,000        260,000         85,000            85,000 Net present value        101,832            46,918 Present Value Index (A/B)               1.39                1.55
