The following information is substitute information provided in accordance with General Instruction J to Form 10-K:

Item 1112(b) of Regulation AB. Significant Obligor Financial Information

No single obligor represents more than 10% of the pool assets held by the Issuing Entity.

Items 1114(b)(2) of Regulation AB. 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) of Regulation AB. Credit Derivatives Instruments

Not applicable.

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 Credit Funding, LLC, as the Depositor (the Depositor) and registrant under Registration Statement Number 333-190926-01 (the Registrant) or
to the Registrants knowledge, The Bank of New York Mellon, 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.

In the ordinary course of business, The Bank of New York Mellon is named as a defendant in or made a party
to pending and potential legal actions. In connection with its role as trustee of certain residential mortgage-backed securitization (RMBS) transactions, The Bank of New York Mellon has been named as a defendant in a number of legal
actions brought by RMBS investors. These lawsuits allege that the trustee had expansive duties under the governing agreements, including the duty to investigate and pursue breach of representation and warranty claims against other parties to the
RMBS transactions. While it is inherently difficult to predict the eventual outcomes of pending actions, The Bank of New York Mellon denies liability and intends to defend the litigations vigorously. The trust identified on the cover of this Form
10-K 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 November 19, 2014 pursuant to Securities Act Rule 424, file number 333-190926-01.

Item 1122 of
Regulation AB. Compliance with Applicable Servicing Criteria

Navient Solutions, Inc., as the Servicer, and Navient Solutions, Inc., as
the Administrator (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.
