What is the 'Gains/Loss Prior to Takeover' number in my portfolio performance statement?

When a PMS account is funded by stocks, the portfolio reporting also computes the gain/loss incurred by the client on stock holdings before the stocks were 'taken over' by Marcellus. This is computed by comparing transfer-to-Marcellus valuation with purchase valuation. 

Gains prior to the takeover are for information purposes only, and do not reflect in the performance of funds at Marcellus, and are not considered for fee computation. All stocks are considered fresh capital into the portfolio on the transfer valuation and performance (and fee) is computed on transfer valuation.
