Changing ownership during the year

Hi All,

My client has a requirement where they would like the periodic profit based on the ownership in that month to be added to the total in December as there are a lot of ownership changes during the year. We have a YTD model and when I run the Year to date consolidation BPC the ownership rate of December is used and not the "weighed" average of the year.

Does anyone know how to achieve this and if there is any such functionality in BPC?

The attached example might make it more clear.

Thanks.
