Credit Enhancement and Other Support, Except for Certain Derivatives No entity or group of affiliated entities provides external credit enhancement or other support with respect to payments on the notes
issued by the Issuing Entity. Items 1115(b)(2) of Regulation AB. Credit Derivatives Instruments No entity or group of affiliated entities provides derivative instruments with respect to payments on the notes issued by the Issuing
Entity. Item 1117 of Regulation AB. Legal Proceedings Other than as stated in the following paragraph, no legal proceedings are pending against the Issuing Entity, Navient Solutions, Inc., as the Sponsor, the Servicer and the Administrator, Navient Funding,
LLC, as the Depositor (the Depositor) and registrant under Registration Statement Number 333-166301 (the Registrant) or to the Registrants knowledge, Deutsche Bank National Trust
Company, as the Indenture Trustee that are or would be material to the holders of the notes issued by the Issuing Entity, nor does the Registrant know of any such proceeding contemplated by any governmental authorities. Deutsche Bank Trust Company Americas (DBTCA) and Deutsche Bank National Trust Company (DBNTC) have been named as
defendants in civil litigation concerning their roles as trustee of certain residential mortgage backed securities (RMBS) trusts. On June 18, 2014, a group of investors (Plaintiff Investors) filed a civil action against DBTCA
and DBNTC in New York State Supreme Court purportedly on behalf of and for the benefit of 544 private-label RMBS trusts asserting claims for alleged violations of the United States Trust Indenture Act of 1939 (as amended), breach of contract, breach
of fiduciary duty and negligence based on DBTCAs and DBNTCs alleged failure to perform their respective obligations as trustee for the applicable trusts (NY Derivative Action). An amended complaint was filed on July 16, 2014,
adding Plaintiff Investors and RMBS trusts to the NY Derivative Action. On November 24, 2014, the Plaintiff Investors moved to voluntarily dismiss the NY Derivative Action without prejudice. Also on November 24, 2014, substantially the same group of
Plaintiff Investors filed a civil action against DBTCA and DBNTC in the United States District Court for the Southern District of New York (the SDNY Action), making substantially the same allegations as the New York Derivative Action
with respect to 564 RMBS trusts (542 of which were at issue in the NY Derivative Action). The SDNY Action is styled both as a derivative action on behalf of the named RMBS Trusts and, in the alternative, as a putative class action on behalf of
holders of RMBS representing interests in those RMBS trusts. DBTCA is vigorously defending the SDNY Action. It is DBTCAs belief that it has no pending legal proceedings (including, based on DBTCAs present evaluation, the litigation
disclosed in this paragraph) that would materially affect its ability to perform its duties as a trustee on behalf of the trust identified on the cover of this Form 10-K. Such trust is not a party to this litigation. Item 1119 of Regulation AB. Affiliations and Certain Relationships and Related Transactions Pursuant to the Instruction to Item 1119 of Regulation AB, information required by Item 1119 has been omitted from this Report
because substantially the same information related to affiliates of the Issuing Entity and certain relationships and related transactions is provided in the section titled The Sponsor, Servicer and Administrator of the base prospectus,
previously filed with the SEC on May 22, 2014 pursuant to Securities Act Rule 424, file number 333-190926. Item 1122 of Regulation AB. Compliance with Applicable Servicing Criteria Navient Solutions, Inc., as the Servicer, Navient Solutions, Inc., as the Administrator and Deutsche Bank National Trust Company, as the Indenture Trustee (collectively, the Servicing Parties)
have each been identified by the Depositor as parties participating in the servicing function with respect to the asset pool held by the Issuing Entity. Each of the Servicing Parties has completed a report on assessment of compliance with the
servicing criteria applicable to it (each a Servicing Report), which Servicing Reports are attached as exhibits to this Form 10-K. Each of the Servicing Parties have provided an attestation report
(each an Attestation Report) by one or more public accounting firms, which reports are also attached as exhibits to this Report. None of the Servicing Reports or Attestation Reports has identified any material instance of noncompliance
with the servicing criteria as applicable to the respective Servicing Party. There have been no material instances of noncompliance with the servicing criteria for the period of this Report. Item 1123 of Regulation AB. Servicer Compliance Statement A Servicer
Compliance Statement for each of Navient Solutions, Inc., as Servicer, and Navient Solutions, Inc., as Administrator, is included as an exhibit to this Report.  4
