In reviewing current operating processes, the company accountant has provided you with the following information (below and Table 1) about a small chemical process that was built ten years ago.

Capital investment = $30 x 10⁶ ($10 x 10⁶ at end of year 1, $15 x 10⁶ at end of year 2, and $5 x 10⁶ at end of year 3)

Working capital = $10 x 10⁶

Table 1. Cash Flow Information

Provide a summary table of values, and the cumulative cash flow diagrams for the non-discounted and discounted cases.

Calculate the following:

Non-discounted payback period (PBP)

Rate of return on investment (ROROI)

Discounted payback period (DPBP) – use a discount rate of 7%

Net present value (NPV) – use a discount rate of 7%

Discounted cash flow rate of return (DCFROR)
