Submit an Excel file with your answers to Problems: 2, 15, 16, 19, and 20, as well as CFA Problems: 2, 3, and 4. For the conceptual problems, just type the answer in Excel; please identify the boundaries of the page so that you use additional rows rather than extending an answer across several pages. For calculation based problems, please use Excel to do the calculations rather than doing them on a calculator and just typing the answers into Excel.
