Essay

An insulated shipping container supplier is considering expanding its product line. Three materials with different insulation properties are under consideration. The following information is prepared for the economic evaluation of the best material. If the company's MARR is 4% per year and the study period is 5 years, use an AW- based incremental rate
of return equation to determine which alternative is preferred. Assume the salvage value is negligible. $$\begin{array} { | l | l | l | l | } \hline \text { Material } & Q & R & S \\\hline \text { First costs } & \$ 46,000 & \$ 58,000 & \$ 61,000 \\\hline \text { Net annual revenue } & \begin{array} { l } \$ 10,000 \text { in year } 1 , \\\text { increasing by } \\\$ 100 \text { per year } \\\text { thereafter }\end{array} & \begin{array} { l } \$ 11,900 , \\\text { increasing by } \\\$ 450 \text { per year } \\\text { thereafter }\end{array} & \$ 13,450 \\\hline \text { IRR (\%) } & 5.93 & 5.15 & 5.14\\\hline \text { Incremental IRR (\%) } & & & \\\hline Q & - & & \\\hline \text { R } & 2.50 \% & - & \\\hline S & 2.79 \% & 5.09 \% & -\\\hline\end{array}$$
