ITEM 1.01  Entry into a Material Definitive Agreement.

On March 2, 2015, Simon Property Group, L.P. (the “Company”) amended and extended its $2.0 billion unsecured multi-currency supplemental revolving credit facility (the “Supplemental Facility”), as summarized in the attached press release.  The Supplemental Facility’s borrowing capacity has been increased from $2.0 billion to $2.75 billion, and can be further increased to $3.5 billion during its term, will initially mature on June 30, 2019 and can be extended for an additional year to June 30, 2020 at the Company’s sole option.  The interest rate on the new Supplemental Facility, based on the Company’s current long-term unsecured credit ratings, is LIBOR plus 80 basis points and an additional facility fee of 10 basis points.  The Supplemental Facility provides for borrowings denominated in U.S. Dollars, Euro, Yen, Sterling, Canadian Dollars and Australian Dollars.  The Supplemental Facility contains a money market competitive bid option program that allows the Company to hold auctions to achieve lower pricing for short-term borrowings.

The Supplemental Facility provides for borrowings for general corporate purposes.

The Supplemental Facility contains ongoing covenants relating to total and secured leverage to capitalization value and minimum EBITDA and unencumbered EBITDA coverage requirements.  Payment under the Supplemental Facility can be accelerated if the Company or its general partner, Simon Property Group, Inc., is subject to a bankruptcy proceeding or upon the occurrence of certain other events.

Prior to the extension and amendment, the Supplemental Facility had a capacity of $2.0 billion, an initial maturity of June 30, 2016, an interest rate of LIBOR plus 95 basis points and an additional facility fee of 15 basis points.

In addition, the Company increased the maximum aggregate size of its global commercial paper note program from $500 million to $1.0 billion, or the non-U.S. dollar equivalent thereof.

The commercial paper notes have not been and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”) or state securities laws, and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.  The information contained in this Current Report on Form 8-K is neither an offer to sell nor a solicitation of an offer to buy any securities.

A copy of the Amended and Restated Supplemental Facility agreement, the Notice of Increase of the global commercial paper note program and the press release are attached hereto as Exhibits 10.1, 10.2 and 99.1, respectively, and are incorporated herein by reference and constitute part of this report.
