At September 30, 2015 and December 31, 2014, the Company had $550.0 million and $481.5 million outstanding, respectively, under the following credit facilities (in thousands):



Credit Facilities	Interest Rate	Initial Maturity	Outstanding Balance at September 30, 2015		Outstanding Balance at December 31, 2014

On January 27, 2015, the Company exercised the accordion feature under its senior unsecured revolving credit facility to increase the facility by $200.0 million to $450.0 million. All other terms and covenants associated with the senior unsecured revolving credit facility remained unchanged as a result of the increase.

On June 26, 2015, the Company entered into a term loan agreement for a $200.0 million five-year unsecured term loan. The unsecured term loan has a maturity date of June 26, 2020, and has an accordion feature that allows for an increase in the size of the unsecured term loan to as much as $400.0 million. Interest on the unsecured term loan is based on LIBOR plus an applicable margin of 0.90% to 1.75% depending on overall Company leverage (with the current rate set at 1.35%). The unsecured term loan has substantially the same operating and financial covenants as required by the Company's $450.0 million senior unsecured revolving credit facility.

The senior unsecured revolving credit facility and unsecured term loans bear interest at LIBOR plus an applicable margin. As a result of the investment grade credit ratings the Company received in January 2015 from S&P and Moody's, the Company has changed to a different pricing grid under its existing credit agreement that is based on the Company's most recent credit rating. The new applicable margin for the senior unsecured revolving credit facility is currently 1.30% resulting in an all-in rate of 1.49%. The new applicable margin for the $250.0 million five-year unsecured term loan is currently 1.40% resulting in a weighted average all-in rate of 2.56%, after giving effect to the floating-to-fixed-rate interest rate swaps. The new applicable margin for the $100.0 million seven-year unsecured term loan is currently 1.85%, resulting in an all-in rate of 4.41%, after accounting for the floating-to-fixed-rate interest rate swap.

Mortgage Notes Payable

Mortgage notes payable at September 30, 2015 totaled $1.2 billion, including unamortized net premiums on debt acquired of $19.0 million, with a weighted average interest rate of 4.1%.

On March 5, 2015, the Company extinguished the mortgage note payable associated with Westshore Corporate Center. The balance at the date of payoff was approximately $14.0 million. The Company recognized a gain on extinguishment of debt of approximately $79,000.

On April 3, 2015, the Company paid in full the $68.0 million Teachers Insurance and Annuity Associations mortgage debt secured by Hillsboro I-IV and V, Peachtree Dunwoody, One Commerce Green and the Comerica Bank Building and incurred a $3.0 million prepayment fee as part of the repayments.

On April 6, 2015, the Company paid in full the $31.9 million first mortgage secured by 3350 Peachtree and incurred a $319,000 prepayment fee as part of the repayment.

Fund II drew approximately $18.4 million on its construction loan secured by the Hayden Ferry Lakeside III development in the Tempe submarket of Phoenix, Arizona during the nine months ended September 30, 2015. As of September 30, 2015, the balance of the construction loan payable was approximately $18.9 million.

Interest Rate Swaps

The Company's objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in Accumulated Other Comprehensive Income (Loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2015, such derivatives were used to hedge the variable cash flows associated with variable-rate debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. See "Note 6 — Fair Values of Financial Instruments," for the fair value of the Company's derivative financial instruments as well as their classification on the Company's consolidated balance sheets as of September 30, 2015 and December 31, 2014.

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company's derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company's known or expected cash receipts and its known or expected cash payments principally related to the Company's investments and borrowings.

Credit Risk-Related Contingent Features

The Company has entered into agreements with each of its derivative counterparties that provide that if the Company defaults or is capable of being declared in default on any of its indebtedness, the Company could also be declared in default on its derivative obligations.

As of September 30, 2015, the fair value of derivatives in a liability position including accrued interest but excluding any adjustment for nonperformance risk related to these agreements was $12.6 million. As of September 30, 2015, the Company has not posted any collateral related to these agreements and was not in default under any of its derivative obligations. If the Company had been in default under any of its derivative obligations, it could have been required to settle its obligations under the agreements with its derivative counterparties at their aggregate termination value of $12.6 million at September 30, 2015.
