This Current Report on Form 8-K is filed by CBRE Group, Inc., a Delaware corporation (the “Company”), in connection with the matters described herein.

On September 23, 2014, the Company, CBRE Services, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (“Services”), and certain of Services’ subsidiaries, entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC, Credit Suisse Securities (USA) LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated, for themselves and on behalf of the several underwriters listed in Schedule A thereto (collectively, the “Underwriters”), relating to the public offering of $300,000,000 in aggregate principal amount of Services’ 5.25% senior notes due 2025 (the “Notes”).

The Notes were offered pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-178800) (as amended, the “Registration Statement”) filed with the Securities and Exchange Commission (the “SEC”), as supplemented by the prospectus supplement, dated September 23, 2014.

The Company intends to use the net proceeds from the Notes, together with cash on hand, to redeem Services’ outstanding 6.625% Senior Notes due 2020.

The Notes are governed by an Indenture, dated as of March 14, 2013 (the “Base Indenture”), among Services, the Company, certain of the subsidiary guarantors parties thereto and Wells Fargo Bank, National Association, as trustee (the “Trustee”), as amended and supplemented by the Second Supplemental Indenture, dated as of September 26, 2014 (the “Second Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), among Services, the Company, the subsidiary guarantors parties thereto and the Trustee.

The Notes will mature on March 15, 2025 and will bear interest at a rate of 5.25% per annum, payable semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2015.

Prior to December 15, 2024, Services will be entitled, at Services’ option, to redeem all or a portion of the Notes at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon to December 15, 2024 (not including any portions of payments of interest accrued as of the date of redemption) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the adjusted treasury rate, as defined in the Indenture. In the case of each of clause (1) and (2), accrued and unpaid interest, if any, will be payable to, but excluding, the date of redemption. From and after December 15, 2024, Services will be entitled, at Services’ option, to redeem all or a portion of the Notes at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption. Upon the occurrence of a change of control triggering event, as defined in the Indenture, Services must give holders of Notes an opportunity to sell to Services’ their notes at 101% of the principal amount of the Notes, plus accrued and unpaid interest, if any, to the date of purchase.

The Company and each subsidiary of Services that guarantees Services’ specified debt, as defined in the Indenture, fully and unconditionally guarantees the Notes on a senior unsecured basis. The guarantees by the guarantors of the Notes will rank pari passu to all existing and future senior indebtedness of the guarantors.

The Notes are senior unsecured obligations of Services. The Notes rank equal in right of payment with Services’ existing and future senior indebtedness and senior in right of payment to any of Services’ existing and future subordinated indebtedness. The Notes and guarantees will be effectively subordinated to all of the Services’ existing and future secured debt to the extent of the value of the assets securing such debt and structurally subordinated to all of the existing and future liabilities of our subsidiaries that do not guarantee the Notes.

The Indenture contains covenants that limit Services’ ability and the ability of certain of Services’ subsidiaries to (i) create certain liens, (ii) enter into sale/leaseback transactions, and (iii) enter into mergers or consolidations. These covenants are subject to a number of important qualifications and exceptions contained in the Indenture.

Events of default under the Indenture include, among others, the following (subject in certain cases to grace and cure periods): nonpayment, breach of covenants in the Indenture, default of payment of principal at final maturity, acceleration of certain indebtedness, failure to pay certain judgments and cessation of the guarantees.

The foregoing description is not complete and is qualified in its entirety by reference to the complete text of the Indenture.

Wells Fargo Bank, National Association, and its affiliates have provided in the past to the Company and its affiliates, and may provide to the Company and its affiliates from time to time in the future, certain commercial banking, financial advisory, investment banking and other services in the ordinary course of business, for which they have received and may receive customary payments of interest, fees and commissions.

The information set forth above under Item 1.01 is hereby incorporated by reference into this Item 2.03.
