Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On November 20, 2013, Camden Property Trust, a Texas real estate investment trust (the “Company”), entered into an underwriting agreement (the “Underwriting Agreement”) with Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc., SunTrust Robinson Humphrey, Inc. and U.S. Bancorp Investments, Inc., for themselves and Representatives of the several Underwriters named therein (the “Underwriters”), pursuant to which the Company agreed to issue and sell to the Underwriters $250,000,000 aggregate principal amount of its 4.250% Notes due 2024 (the “Notes”), which issuance and sale is scheduled to close on December 2, 2013. A copy of the Underwriting Agreement is filed as Exhibit 1.1 hereto and incorporated by reference herein.

The offering of the Notes is described in the Company’s Prospectus Supplement dated November 20, 2013 to the Company’s Prospectus dated November 9, 2011. The Notes will be issued pursuant to the Company’s existing shelf registration statement.

After deducting underwriting discounts and other offering expenses, the net proceeds from the sale of the Notes will be approximately $247.4 million. The Company intends to use the net proceeds to pay at maturity the $200 million aggregate principal amount outstanding of its 5.375% Senior Notes due December 15, 2013, plus accrued and unpaid interest to the date of maturity, and the remainder to repay any outstanding balance on its unsecured line of credit and other short-term borrowings and for general corporate purposes, which may include property acquisitions and development in the ordinary course of business, capital expenditures and working capital. In the ordinary course of their respective businesses, the underwriters and their affiliates have engaged, and may in the future engage, in commercial banking and/or investment banking transactions with the Company and its affiliates for which they have received, and may in the future receive, customary fees. U.S. Bank National Association, an affiliate of U.S. Bancorp Investments, Inc., one of the Underwriters, is serving as the trustee under the indenture under which the Notes will be issued. Affiliates of certain of the Underwriters are lenders under the Company’s unsecured line of credit and/or other short-term borrowings and certain of the Underwriters and/or their respective affiliates may hold a position in the Company’s 5.375% Senior Notes due December 15, 2013. Such underwriters or affiliates will, therefore, receive a portion of the net proceeds of the Notes through any repayment of borrowings on the unsecured line of credit and/or other short-term borrowings or the repayment of the 5.375% Senior Notes due December 15, 2013, as the case may be.
