    paragraph_quote: '6307.1: Co-Issue XChange® (01/01/26) This section contains:
      ■ Seller participation requirements for Co-Issue XChange® ■ Other Guide provisions
      related to Co-Issue XChange and Transfers of Servicing ■ Co-Issue XChange cash
      pricing ■ Funding adjustments and net funding The provisions of this chapter
      apply to Mortgages sold through Co-Issue XChange, one of the executions available
      under Servicing-Released XChange®, Freddie Mac’s suite of executions that provides
      market liquidity for Servicing Contract Rights and helps Sellers transfer Servicing
      Contract Rights to a Freddie Mac-approved Servicer. (a) Seller participation
      requirements for Co-Issue XChange To participate in Co-Issue XChange as a Seller
      pursuant to the terms of Exhibit 26, Agreement for Concurrent Transfer of Single-Family
      Mortgage Servicing Contract Rights With Complete/Full Bifurcation, the Seller
      must apply to Freddie Mac for approval. To inquire about the Co-Issue XChange
      Originator approval process, Sellers should contact their Freddie Mac representative
      or call Customer Service at 800-FREDDIE. Freddie Mac-approved Sellers will receive
      access to the Co-Issue XChange execution option in Loan Selling Advisor®. (b)
      Other Guide provisions related to Co-Issue XChange and Transfers of Servicing
      See Sections 7101.1(b) and 7101.3(c) through (f) for additional information
      and requirements pertaining to Transfers of Servicing. (c) Co-Issue XChange
      cash pricing Freddie Mac has developed a process under Co-Issue XChange that
      is available through Loan Selling Advisor that permits a Seller to: ■ Obtain
      a price from, and simultaneously sell Mortgages to, Freddie Mac, ■ Transfer
      the Servicing Contract Rights related to those Mortgages to a Servicer, and
      Freddie Mac Single-Family Seller/Servicer Guide Chapter 6307 As of 01/01/26
      Page 6307-2 ■ Receive a price from Freddie Mac that includes the purchase of
      the Mortgage(s) and the price offered by the Transferee Servicer for the Servicing
      Contract Rights related to each Mortgage (the “Co-Issue All-in Price Process”).
      The Seller may participate in the Co-Issue All-in Price Process only if the
      Servicer has elected with Freddie Mac to participate in the Co-Issue All-in
      Process with the Seller. Prices and fees provided when the Seller enters into
      a Mandatory Cash Contract or a Best Efforts Contract through Co-Issue XChange
      are not final; instead, the prices and fees are determined as of the Funding
      Date based on the Mortgage data provided by the Seller. The Seller must supply
      all Mortgage data requested by Loan Selling Advisor (in the fields titled “Loan
      Fields Required for Pricing” and “Additional Loan Fields That Affect Pricing”)
      so the Servicer may provide an accurate bid for the assignment and assumption
      of the Servicing Contract Rights. (d) Funding adjustments and net funding Funding
      adjustments are composed of the Escrow funds, interest adjustment, Servicing
      Spread, tax service fee, transaction fee and temporary subsidy buydown funds.
      The amount of funding adjustments will be identified on the Funding Date as
      follows: ■ The Seller enters in Loan Selling Advisor the amounts held as Escrow
      funds and temporary subsidy buydown funds for each Mortgage sold servicing-released,
      and ■ Loan Selling Advisor calculates the interest adjustment, Servicing Spread,
      tax service fee and transaction fee Refer to Section 6302.51 for additional
      information regarding delivery requirements for Mortgages sold servicing-released
      under Mandatory Cash Contracts or Best Efforts Contracts. The Seller is responsible
      for the accuracy of the Escrow fund amounts and temporary subsidy buydown fund
      amounts that the Seller submits via Loan Selling Advisor. Freddie Mac does not
      edit or validate these amounts. On the Funding Date, Freddie Mac will deduct
      the amount of the funding adjustments from the sales proceeds paid by Freddie
      Mac for the purchase of each Mortgage sold through Co-Issue XChange. Freddie
      Mac will forward the deducted amount of the funding adjustments to the Servicer.
      The Seller and the Servicer are responsible for any reconciliation, correction
      or adjustment to the amount of Escrow funds or temporary subsidy buydown funds
      transferred to the Servicer. Freddie Mac will not adjust, calculate, refund
      or pay any amounts with respect to the Escrow funds or temporary subsidy buydown
      funds after the Funding Date. Freddie Mac Single-Family Seller/Servicer Guide
      Chapter 6307 As of 01/01/26 Page 6307-3 Freddie Mac will conduct quality control
      activities relating to the sale representations and warranties with the Seller.
      The Seller agrees that Freddie Mac may share with the Transferee Servicer information
      regarding the Mortgages sold to Freddie Mac through Co-Issue XChange, including,
      but not limited to, quality control findings, the Seller’s response to quality
      control findings and defect reports. Freddie Mac Single-Family Seller/Servicer
