Reading 43, Problem #24:

Why isn’t the contribution on May 15 of $1,000,000 subtracted from the numerator like they were in Problems #7 and #9?

A or B part?

In A they calculate the actual TW return for the whole month, NOT mmodified Dietz like #7.

Part A is not TW return…true TW return would chain-link multiple partial period returns.

My question is: why do they adjust the denominator by adding the weighted contribution just like the modified Dietz method, but don’t subsequently subtract the contribution from the numorator like the modified Dietz?

7 and 9 are approx **total** return using mod dietz

24 is total return broken down as capital return + income return

24A is capital return

24 is really the conventional accounting calculation of return (note the use of actual capital beginning rather than fair value beginning) —

mod dietz is an approx working with FV

Thanks.
