# Weighted average question

 Emeritus Sci Advisor PF Gold P: 4,500 Based on the footnote (3) and (4) it sounds like the weighted average is not related to currency changes, they just assumed a flat exchange rate by averaging the exchange rate over the whole period. It sounds like the weights in the average are supposed to be the percents at the bottom of the page, but I don't understand how they are averaging the adjusted cash and coming up with a number larger than any of the individual adjusted cash numbers. If I didn't know this gave the wrong number I would think the calcuation they are doing is $$\frac{3167.3*(.875+.625+.375+.125) + 2570.9*4 + 2056*4 + 1655.3*(.875+.625+.375+.125) }{8+2*(.875+.625+.375+.125)}$$
