PRELIMINARY STATEMENT (Terms used but not defined in this Preliminary Statement shall have the meanings specified in Article I hereof) The Depositor intends to sell pass-through certificates to be issued hereunder in multiple classes which in the aggregate will evidence the entire beneficial ownership interest in the Trust Fund consisting primarily of the Mortgage Loans (including, in the case of the One Court Square Mortgage Loan, the One Court Square Trust REMIC Regular Interests). As provided herein, the Certificate Administrator will elect that two segregated portions of the Trust Fund (other than the Class A-S Specific Grantor Trust Assets, the Class B Specific Grantor Trust Assets, any Excess Interest Grantor Trust Assets, the Class C Specific Grantor Trust Assets, the Class EC Specific Grantor Trust Assets and the proceeds of the foregoing) be treated for federal income tax purposes as two separate REMICs (designated as the “Upper-Tier REMIC” and the “Lower-Tier REMIC”, respectively). The Regular Certificates and the Class EC Regular Interests will represent “regular interests” in the Upper-Tier REMIC, and the Upper-Tier Residual Interest will be the sole class of “residual interests” in the Upper-Tier REMIC. There are also (i) 12 classes of uncertificated Lower-Tier Regular Interests issued under this Agreement (designated as the Class XX-0, Xxxxx XX-0, Class LA-3, Class LA-4, Class LA-AB, Class LA-S, Class LB, Class LC, Class LD, Class LE, Class LF and Class LG Interests), each of which will constitute a class of “regular interests” in the Lower-Tier REMIC, and (ii) the Lower-Tier Residual Interest, which will be the sole class of “residual interests” in the Lower-Tier REMIC. The Lower-Tier Regular Interests will be held by the Trustee as assets of the Upper-Tier REMIC. The Class R Certificates will represent both the Lower-Tier Residual Interest and the Upper-Tier Residual Interest. In addition, on October 13, 2015, NREC formed the One Court Square REMIC with respect to part of the One Court Square Loan Combination, which issued three pro rata and pari passu regular interests (the “One Court Square REMIC A-1 Regular Interest”, the “One Court Square REMIC A-2 Regular Interest” and the “One Court Square REMIC A-3 Regular Interest (each, a “One Court Square REMIC Regular Interest”, and collectively, the “One Court Square REMIC Regular Interests”). Each One Court Square REMIC Regular Interest has a principal balance set forth below and for tax reporting purposes will be entitled to principal and interest and any other amounts payable on the One Court Square REMIC Regular Interest in the same proportion that its principal balance bears to the aggregate principal balance all of the One Court Square REMIC Regular Interests, as set forth below: One Court Square REMIC Regular Interest Corresponding One Court Square promissory note(s) Initial Principal Balance One Court Square REMIC A-1 Regular Interest One Court Square Promissory Note A-1 $50,000,000 One Court Square REMIC A-2 Regular Interest One Court Square Promissory Note X-0, Xxx Xxxxx Xxxxxx Xxxxxxxxxx Xxxx X-0 $95,000,000 One Court Square REMIC A-3 Regular Interest One Court Square Promissory Note X-0, Xxx Xxxxx Xxxxxx Xxxxxxxxxx Xxxx X-0 $90,000,000 Each One Court Square REMIC Regular Interest holder will be the owner of a percentage interest, specified below, in its corresponding One Court Square Promissory Note(s) other than for tax reporting purposes.
