BioCom was founded in 1993, when several scientists and engineers at a large fiber-optic-cable company began to see that optical fiber for the telecommunications industry was becoming a cheap commodity. They decided to start their own firm, which would specialize in cutting-edge applications for research in the life sciences and medical instruments. BiocCom is now one of the leading firms in its niche field. BioComs management attributes the firms success to its ability to stay one step ahead of the markets fast-changing technological needs. Almost as important is BioComs ability to select high-value-added projects and avoid commercial disasters.

Over lunch, BioComs director of research and development (R&D) mentioned to the CFO that one of his best young scientists had recently left the company because his line manager had rejected his project. Although not a pattern, R&D had experienced similar losses in the past. The two executives discussed the problem and agreed that if the r&D people understood the selection process better, they might come up with more commercially viable projects and understand the projects financial implications. The CFO has asked his assistant, Jane Donato, to prepare a retreat for the R&D department to explain the company's project selection procedures. Jane is encouraged by the thought that this group will have no trouble in following the math.

BioComs standard capital request form includes a narrative description of the project and the customer need that the company must fulfill. If the request originates with R&D, it then goes to the marketing department for a preliminary sales forecast and then to the production manager and cost analysts for cost estimates. If a proposal shows promise after these steps, it goes to the CFO, who has a staff member enter the data into a spreadsheet template. The template computes playback, discounted payback, net present value, internal rate of return, and modified internal rate of return. BioCom uses net present value as its primary decision criterion, but company executives believe that the other statistics provide some useful additional perspectives.

To explain BioComs capital budgeting techniques, Jane has decided to present the cash flows from two recent proposals: the nano test tube project and the microsurgery kit project. All figures are in thousands of dollars:

REQUIRED

1. Compute the payback period for the Nano Test Tubes project to the nearest tenth of a year.

2. Compute the payback period for the Microsurgery Kit project to the nearest tenth of a year.

3. Compute the discounted payback period for Nano Test Tubes using a discount rate of 7% to the nearest tenth of a year.

4. Compute the discounted payback period for the Microsurgery Kit project using a discount rate of 7% to the nearest tenth of a year.
