positions and collateral of the defaulting firm at each respective clearing organization , and taking into account any cross-margining loss sharing payments , any of the participating clearing organizations has a remaining liquidating surplus , and any other participating clearing organization has a remaining liquidating deficit , any additional surplus from the liquidation would be shared with the other clearing house to the extent that it has a remaining liquidating deficit . any remaining surplus funds would be passed to the bankruptcy trustee . mf global bankruptcy trust . the company provided a $ 550.0 million financial guarantee to the bankruptcy trustee of mf global to accelerate the distribution of funds to mf global customers . in the event that the trustee distributed more property in the second or third interim distributions than was permitted by the bankruptcy code and cftc regulations , the company will make a cash payment to the trustee for the amount of the erroneous distribution or distributions up to $ 550.0 million in the aggregate . a payment will only be made after the trustee makes reasonable efforts to collect the property erroneously distributed to the customer ( s ) . if a payment is made by the company , the company may have the right to seek reimbursement of the erroneously distributed property from the applicable customer ( s ) . the guarantee does not cover distributions made by the trustee to customers on the basis of their claims filed in the bankruptcy . because the trustee has now made payments to nearly all customers on the basis of their claims , the company believes that the likelihood of payment to the trustee is very remote . as a result , the guarantee liability is estimated to be immaterial at december 31 , 2012 . family farmer and rancher protection fund . in april 2012 , the company established the family farmer and rancher protection fund ( the fund ) . the fund is designed to provide payments , up to certain maximum levels , to family farmers , ranchers and other agricultural industry participants who use cme group agricultural products and who suffer losses to their segregated account balances due to their cme clearing member becoming insolvent . under the terms of the fund , farmers and ranchers are eligible for up to $ 25000 per participant . farming and ranching cooperatives are eligible for up to $ 100000 per cooperative . the fund has an aggregate maximum payment amount of $ 100.0 million . if payments to participants were to exceed this amount , payments would be pro-rated . clearing members and customers must register in advance with the company and provide certain documentation in order to substantiate their eligibility . peregrine financial group , inc . ( pfg ) filed for bankruptcy protection on july 10 , 2012 . pfg was not one of cme 2019s clearing members and its customers had not registered for the fund . accordingly , they were not technically eligible for payments from the fund . however , because the fund was newly implemented and because pfg 2019s customers included many agricultural industry participants for whom the program was designed , the company decided to waive certain terms and conditions of the fund , solely in connection with the pfg bankruptcy , so that otherwise eligible family farmers , ranchers and agricultural cooperatives could apply for and receive benefits from cme . based on the number of such pfg customers who applied and the estimated size of their claims , the company has recorded a liability in the amount of $ 2.1 million at december 31 , 2012 . 16 . redeemable non-controlling interest the following summarizes the changes in redeemable non-controlling interest for the years presented . non- controlling interests that do not contain redemption features are presented in the statements of equity. .
