Item 1114(b)(2) of Regulation AB. Credit Enhancement and Other Support Except for Certain Derivatives Instruments (Information Regarding Significant Enhancement Providers)

None.

Item 1115(b) of Regulation AB. Certain Derivative Instruments (Financial Information)

No entity or group of affiliated entities provides any derivative instruments that are used to alter payments characteristics of the cash flows from the Trust.

Item 1117 of Regulation AB. Legal Proceedings

No legal proceedings are pending against any of California Republic Bank (the “Sponsor”), California Republic Funding, LLC (the “Depositor”), or the Trust, or against any property of any such entities that are or would be material to holders of the Notes or certificates (the “Certificates”) issued by the Trust.

Deutsche Bank Trust Company Americas (“DBTCA”), the Indenture Trustee with respect to the Trust, has provided the following disclosure:

DBTCA has been named as a defendant in civil litigation concerning its role 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 Deutsche Bank National Trust Company (“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 Trust Indenture Act of 1939, breach of contract, breach of fiduciary duty and negligence based on DBTCA’s and DBNTC’s alleged failure to perform their obligations as trustees for the trusts (the “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. DBTCA 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 indenture trustee on behalf of the noteholders.

Item 1119 of Regulation AB. Affiliations and Certain Relationships and Related Transactions.

The Sponsor is the originator, as contemplated by Item 1110 of Regulation AB, of all the pool assets owned by the Trust. The Sponsor is also the primary servicer. The Depositor is a wholly-owned subsidiary of the Sponsor and, therefore, a wholly-owned subsidiary of the originator and the primary servicer.

The Indenture Trustee is not affiliated with the Sponsor (including in its role as originator and primary servicer), the Depositor, or the Trust. The Owner Trustee is not affiliated with the Sponsor or the Depositor.

3

There are no significant obligors or support providers, or other material parties related to the Notes or Certificates.

In addition, there are no business relationships, agreements, arrangements, transactions or understanding outside the ordinary course of business or on terms other than would be obtained in an arm’s length transaction with an unrelated party, apart from the transaction involving the issuance of the Notes and Certificates by the Trust, between the Sponsor, the Depositor or the Trust and any of the parties mentioned in this Item.

Item 1122 of Regulation AB. Compliance with Applicable Servicing Criteria.

The Sponsor (in its role as servicer), and the Indenture Trustee (the Sponsor, as servicer, and the Indenture Trustee collectively as the “Servicing Participants”) have each been identified by the Depositor as participating in the servicing function with respect to the asset pool held by the Trust. The Servicing Participants have each completed a report on an assessment of compliance with its respective servicing functions (each, a “Servicing Report”), which Servicing Reports are attached as exhibits to this Form 10-K. Neither the Servicing Reports prepared by any of the Servicing Participants, nor the Attestation Reports provided by the Servicing Participants’ respective registered public accounting firms have identified any material instance of noncompliance with the servicing criteria applicable to the respective Servicing Participant.

Item 1123 of Regulation AB. Servicer Compliance Statement.

The Sponsor (in its role as servicer) has been identified by the Depositor as a servicer with respect to the asset pool held by the Trust. The Sponsor has completed a statement of compliance with applicable servicing criteria (the “Compliance Statement”), signed by an authorized officer of the Sponsor. The Compliance Statement is attached as an exhibit to this Form 10-K.
