The numbers below are from the current analysis. Ratios do not take into account all of the cash flows, and are not a discounted cash flow measure like NPV, hence do not reflect the true yield for the analysis. Cash flows with the * symbol are partial years where the partial number has been divided by the number of months and multipled by 12.
