Fair Value Measurements

Fair value guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers are defined as follows:

Level 1
Defined as observable inputs such as quoted prices in active markets
Level 2
Defined as inputs other than quoted prices in active markets that are either directly or indirectly observable
Level 3
Defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions

We had no assets or liabilities measured at fair value on either a recurring or non-recurring basis as of September 30, 2013 or December 31, 2012.

The estimated fair value of our debt, consisting of senior unsecured notes, unsecured term loans, secured mortgages and unsecured lines of credit, at September 30, 2013 and December 31, 2012, was $1.4 billion and $1.2 billion, respectively, and its recorded value was $1.3 billion and $1.1 billion, respectively. Fair values were determined based on level 2 inputs using discounted cash flow analysis with an interest rate or credit spread similar to that of current market borrowing arrangements.
