RE:RE:RE:RE:Estimated NAV end of March 8What I do in my calculations is keeping the newest declared number of units for each holding: I don't perform any weight re-balancing since there are too many factors that can influence the NAV, including the heavily rounded cash amount declared - in this case, the declared 7% could be anything between 6.5% to 7.49% hence the value of all stock holdings can be anywhere between 92.51% and 93.5%, giving this way a large space for miscalculating the current number of owned stocks for each holding.
To overcome this problem, I calculate a "Trade adjustment" based on the Total Assets value minus the estimated cash value minus the estimated total stock holdings value. The calculated estimated NAV comes from the Total Assets value divided by the estimated number of outstanding shares (which are recalculated in approximation every end of month based on the declared unit value and the declared Total Asset value).
Of course, these calculations cannot be very precise because they are based on very heavily rounded factors: I describe the cash value range above while the declared stock value at month-end and at mid-month has a range of plus or minus 0,5 cents.
All of this to say that my calculations are not perfect but up to now they have kept me pretty close to the real NAV value.
