      Introduction This topic provides information on the factors used to determine
      the amount of a lender’s guaranty fee, including: Guaranty Fee Overview Determining
      the Annualized Weighted-Average Guaranty Fee Factor for a Pool Determining the
      Monthly Guaranty Fee Remittance for the Pool Remitting Guaranty Fees to Fannie
      Mae Guaranty Fee Overview The guaranty fee for individual loans included in
      an MBS pool depends upon the credit risk associated with the loan and the lender’s
      choice of servicing option and remittance cycle. The guaranty fee remittance
      for MBS pools is based upon a weighted-average guaranty factor. See below for
      a description of how to calculate the annualized weighted-guaranty factor and
      the pool guaranty fee. Determining the Annualized Weighted-Average Guaranty
      Fee Factor for a Pool The annualized weighted-average guaranty fee factor for
      a pool (expressed in basis points) is determined by multiplying the issue date
      principal balance of each mortgage loan in the pool (or, in subsequent months,
      the Published May 6, 2026 990 “scheduled” balance of each mortgage loan) by
      the applicable guaranty fee rate for the mortgage loan expressed in basis points
      (adjusted for any remittance cycle adjustments, buyup, or buydown, if applicable),
      then: summing the products of all the mortgage loans in the pool, dividing that
      sum by the aggregate issue date principal balance for the pool (or, in subsequent
      months, by the “scheduled” security balance for the pool), and rounding the
      result to the nearest hundredth of a basis point. The result is the annualized
      weighted-average guaranty fee factor for a pool. Determining the Monthly Guaranty
      Fee Remittance for the Pool The annualized weighted-average guaranty fee factor
      is then multiplied by the aggregate issue date principal balance of the pool
      (or, in subsequent months, the “scheduled” security balance for the pool), divided
      by 120,000, and rounded to two decimal places. The result is monthly guaranty
      fee remittance for the pool. Remitting Guaranty Fees to Fannie Mae On the 7th
      day of each month (or, if the 7th is a holiday or weekend, on the preceding
      business day), Fannie Mae will draft guaranty fee remittances from the custodial
      bank account the lender designates as its draft account. If the guaranty fee
      remittance is to be drafted from the lender’s P&I custodial account for MBS
      pools, then the lender must make sure that it does not withdraw the guaranty
      fee remittance when it takes its monthly servicing fee from the account. For
      more information about designating bank accounts for drafting purposes and conﬁrming
      guaranty fee remittances, see the Servicing Guide. Recent Related Announcements
