Fair Value Measurements | Note 7. Fair Value Measurements
Under current authoritative accounting guidance for fair value measurements, the fair value of an asset is defined as the exit price, which is the amount that would either be received when an asset is sold or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance establishes a three-tier fair value hierarchy based on the inputs used in measuring fair value. These tiers are: Level 1, for which quoted market prices for identical instruments are available in active markets, such as money market funds, equity securities and U.S. Treasury securities; Level 2, for which there are inputs other than quoted prices included within Level 1 that are observable for the instrument, such as certain derivative instruments including interest rate caps and swaps; and Level 3, for which little or no market data exists, therefore requiring us to develop our own assumptions, such as certain securities that do not fall into Level 1 or Level 2.
Items Measured at Fair Value on a Recurring Basis
The methods and assumptions described below were used to estimate the fair value of each class of financial instrument. For significant Level 3 items we have also provided the unobservable inputs along with their weighted average ranges.
Money Market Funds — Our money market funds consisted of government securities and U.S. Treasury bills. These funds were classified as Level 1 as we used quoted prices from active markets to determine their fair values.
Derivative Liabilities — Our derivative liabilities are primarily comprised of interest rate swaps. These derivative instruments were measured at fair value using readily observable market inputs, such as quotations on interest rates. These derivative instruments were classified as Level 2 because they are custom, over-the-counter contracts with various bank counterparties that are not traded in an active market.
Other Securities — Our other securities are primarily comprised of our investment in an India growth fund and our interest in a commercial mortgage loan securitization. These funds are not traded in an active market. We estimated the fair value of these securities using internal valuation models that incorporate market inputs and our own assumptions about future cash flows. We classified these assets as Level 3.
Redeemable Noncontrolling Interest — We account for the noncontrolling interest in WPCI as a redeemable noncontrolling interest. We determined the valuation of the redeemable noncontrolling interest using widely accepted valuation techniques, including expected discounted cash flows of the investment as well as the income capitalization approach, which considers prevailing market capitalization rates. We classified this liability as Level 3. Unobservable inputs for WPCI include a discount for lack of marketability, a discount rate and EBITDA multiples with weighted average ranges of 20% – 30%, 23% – 27% and 3x – 5x, respectively. Significant increases or decreases in any one of these inputs in isolation would result in significant changes in the fair value measurement.
The following tables set forth our assets and liabilities that were accounted for at fair value on a recurring basis. Assets and liabilities presented below exclude assets and liabilities owned by unconsolidated jointly-owned investments (in thousands):
We did not have any transfers into or out of Level 1, Level 2 and Level 3 measurements during the three months ended March 31, 2012 and 2011. Gains and losses (realized and unrealized) included in earnings for other securities are reported in Other income and (expenses) in the consolidated financial statements.
Our other financial instruments, which we classify as Level 2, had the following carrying values and fair values as of the dates shown (in thousands):
We determined the estimated fair value of our debt instruments using a discounted cash flow model with rates that take into account the credit of the tenants, where applicable, and interest rate risk. We estimated that our other financial assets and liabilities (excluding net investments in direct financing leases) had fair values that approximated their carrying values at both March 31, 2012 and December 31, 2011.
Items Measured at Fair Value on a Non-Recurring Basis
We perform an assessment, when required, of the value of certain of our real estate investments in accordance with current authoritative accounting guidance. As part of that assessment, we determine the valuation of these assets using widely accepted valuation techniques, including expected discounted cash flows or an income capitalization approach, which considers prevailing market capitalization rates. We review each investment based on the highest and best use of the investment and market participation assumptions. We determined that the significant inputs used to value these investments fall within Level 3. As a result of our assessments, we calculated impairment charges, which were based on market conditions and assumptions that existed at the time. The valuation of real estate is subject to significant judgment and actual results may differ materially if market conditions or the underlying assumptions change. The following table presents information about our other assets that were measured on a fair value basis for the periods presented (in thousands):
