I need help with the financial analysis tab on my ACC workbook assignment. Specifically, I need help understanding the investment performance tab.

\begin{tabular}{|c|c|c|c|c|} \hline \multicolumn{4}{|c|}{ Investment Performance } \\ \hline Numerator & & Denominator & = & Ratio \\ \hline Interest and Dividend Income +/- Gains and Losses & & Average Fair Value of Investments & & \\ \hline$56,680 & $0 & $0 #DIV/0! \\ \hline \end{tabular}
