      Introduction This topic includes speciﬁcs on pool data and documentation delivery
      requirements, including: Required Documents for MBS Pool Loans General MBS Pool
      Delivery Requirements MBS Pool Data Delivery Requirements MBS Pool Document
      Delivery Requirements As Soon As Pooled Plus Loan Deliveries and Redeliveries
      as As Soon As Pooled Plus Pools Required Documents for MBS Pool Loans See E-2-01,
      Required Custodial Documents for a list of mortgage documents that should be
      included in the document submission package for all loans. See also C3-7-07,
      Sale of Fannie Mae Securities to Third Parties for additional information. General
      MBS Pool Delivery Requirements A lender must deliver the mortgage document submission
      package to the document custodian at the same time it transmits the loan delivery
      data to Fannie Mae. The submission package must be sent to the assigned document
      custodian and addressed according to the instructions provided by that custodian.
      The custodian must then complete the required loan certiﬁcation prior to pool
      closing, which must occur before Fannie Mae issues the related securities. The
      lender must allow suﬃcient processing time between the time it submits its loan
      delivery data and the document submission package and the time it wants the
      securities to be issued in book-entry form. See C3-7-07, Sale of Fannie Mae
      Securities to Third Parties for additional information. For additional information
      on the eligibility criteria for document custodians, see the RDC guide. For
      a complete list of active document custodians, refer to Fannie Mae''s Active
      Document Custodians. MBS Pool Data Delivery Requirements When the lender transmits
      its loan delivery data, it must include a Delivery Schedule in Loan Delivery
      for MBS pools. The Delivery Schedule identiﬁes the parties to which the securities
      are to be issued. If the lender markets and sells the securities before it submits
      its pool documentation to Fannie Mae, it must provide instructions related to
      the delivery of the securities on this form. The lender must enter loan data
      into Loan Delivery. Data should include the Financial Institution Number (FIN)
      of the applicable document custodian. When submitting loan delivery data to
      Fannie Mae, the lender represents and warrants all of the following: Published
      May 6, 2026 1024 the data is correct, each loan listed is to be transferred
      to Fannie Mae on the book-entry delivery date of the related securities, and
      the loans will be delivered and serviced in accordance with the terms of the
      MBS commitment and Fannie Mae’s Guides. For information about speciﬁc FIN codes,
      see Loan Delivery Data Requirements. Lenders delivering into Fannie Majors must
      include the Fannie Majors pool and CUSIP number in their deliveries. The lender
      may submit data for loans in the same Fannie Majors at diﬀerent times and on
      diﬀerent days of the month, as long as all of the loans submitted are the same
      product type and have the same remittance cycle and servicer. All Fannie Major
      deliveries must be error-free and certiﬁed by 5:00 p.m. ET on the third to last
      business day before the end of the month. Example In the following calendar
      example, the third to last business day of the month is Monday the 29th. Sunday
      Monday Tuesday Wednesday Thursday Friday Saturday 21 22 23 24 25 26 27 28 29
      30 31 Lender submissions must align to the eligible settlement dates as published
      on the applicable Pool Settlement Calendar for the issue month of the submission.
      Data submission must be transmitted in Loan Delivery by 7:00 p.m. ET on the
      published last day to submit to be eligible for delivery to Fannie Mae in that
      issue month. For more information on eligible settlement and submission dates,
      see the Loan Delivery page on Fannie Mae’s website. Fannie Mae must have received
      the lender’s loan delivery data for a speciﬁc MBS pool transaction by the time
      it receives the document custodian’s electronic certiﬁcation for the pool. Loan
      delivery data is sent electronically to the document custodian and Fannie Mae
      at the same time, via Loan Delivery. If the lender fails to deliver the required
      delivery data for any speciﬁc MBS pool transaction to Fannie Mae, Fannie Mae
      may terminate the related MBS commitment by giving the lender written notice
      of the termination. Fannie Mae will telephone the lender in advance to inform
      it that a written termination notiﬁcation is being sent. MBS Pool Document Delivery
      Requirements The lender must have a custodial arrangement for each MBS pool
      transaction it delivers to Fannie Mae. The seller must add the document custodian
      to its proﬁle within the Loan Delivery application. In addition, the seller
      must submit the FIN code for the document custodian in the delivery ﬁle. The
      FIN code allows the data to be routed to the proper document custodian. Failure
      to specify the proper FIN may result in a delay of certiﬁcation and/or MBS pool
      securitization. However, if an MBS pool contains one or more ASAP Plus loans,
      all loans within the pool must be certiﬁed by the custodian who certiﬁed the
      ASAP Plus delivery. See ASAP Plus Loan Deliveries and Redeliveries as ASAP Plus
      Pools below, for additional details. Published May 6, 2026 1025 Once the lender
      has the applicable Master Custodial Agreement (Form 2017) on ﬁle with Fannie
      Mae for each of the diﬀerent document custodians it uses, the lender will not
      need to advise Fannie Mae about the speciﬁc custodial arrangement for speciﬁc
      MBS pools when they are delivered. See A3-3-04, Document Custodians for additional
      information. When a lender delivers loans into an MBS, it must send documentation
      on each mortgage to its document custodian for certiﬁcation and retention of
      physical custody, from that point forward, pending successful completion of
      the loan acquisition transaction. The lender should ensure that the mortgage
      document submission package is submitted to its overnight carrier (with instructions
      for ﬁrst morning delivery) the same day that the lender submits the loan data
      to Fannie Mae for purchase. Fannie Mae will certify loan data delivered by the
      lender the following business day, provided the documents have been delivered
      to the document custodian via ﬁrst morning delivery, and there are no discrepancies
      and no unresolved lien issues. See E-1-02, List of Contacts. When the document
      custodian receives the mortgage document submission package, it will review
      the related mortgage documentation to verify all of the required documents have
      been received and are in order. The document custodian will then work with the
      lender to correct any certiﬁcation data or document errors. Lenders can opt-in
      to receive email notices through Loan Delivery when data or document discrepancies
      are noted during certiﬁcation. Lenders then have the option to accept or decline
      data changes the custodian proposes as a result of a discrepancy on the note
      and the data they provided. The lender must work with the custodian to ensure
      all discrepancies are resolved. If there are no document or data-related errors,
      the document custodian will transmit a certiﬁcation to Fannie Mae. As Soon As
      Pooled Plus Loan Deliveries and Redeliveries as As Soon As Pooled Plus Pools
      In addition to the instructions above in MBS Pool Document Delivery Requirements,
      the following requirements also pertain to As Soon As Pooled Plus loan deliveries
      and redeliveries. If lenders opt to redeliver an As Soon As Pooled Plus loan
      as a whole loan execution to Fannie Mae, they must redeliver the loan to Fannie
      Mae via Loan Delivery. When an As Soon As Pooled Plus loan is redelivered as
      a whole loan, the lender must include the FIN code upon redelivery. Failure
      to specify the proper code may result in a delay of certiﬁcation and/or purchase
      of the loan. If lenders opt to redeliver an As Soon As Pooled Plus loan as an
      MBS execution to Fannie Mae, they should redeliver the loan to Fannie Mae via
      Loan Delivery. If an MBS pool contains one or more As Soon As Pooled Plus loans,
      all ASAP Plus loans within the pool must be certiﬁed by the same document custodian
      who certiﬁed the ASAP Plus loan. In addition, the lender must transmit all of
      the loans in the pool with the same document custodian FIN code. The lender
      must also add the document custodian to its proﬁle within the Loan Delivery
      application. Failure to specify the proper FIN code may result in a delay of
      certiﬁcation and/or purchase of the loan. Recent Related Announcements The table
