Interest Rate Derivatives.
In connection with the issuance of floating rate debt in August and October 2008, the company entered into three interest rate swap contracts, designated as cash flow hedges, for purposes of hedging against a change in interest payments due to fluctuations in the underlying benchmark rate.
In December 2010, the company approved a plan to refinance the term loan in January 2011 resulting in an $8.6 million loss on derivative instruments as a result of ineffectiveness on the associated interest rate swap contract.
To mitigate counterparty credit risk, the interest rate swap contracts required collateralization by both counterparties for the swaps’ aggregate net fair value during their respective terms.
Collateral was maintained in the form of cash and adjusted on a daily basis.
In February 2010, the company entered into a forward starting interest rate swap contract, designated as a cash flow hedge, for purposes of hedging against a change in interest payments due to fluctuations in the underlying benchmark rate between the date of the swap and the forecasted issuance of fixed rate debt in March 2010.
The swap was highly effective.
Foreign Currency Derivatives.
In connection with its purchase of BM&FBOVESPA stock in February 2008, CME Group purchased a put option to hedge against changes in the fair value of BM&FBOVESPA stock resulting from foreign currency rate fluctuations between the U. S.  dollar and the Brazilian real (BRL) beyond the option’s exercise price.
Lehman Brothers Special Financing Inc.  (LBSF) was the sole counterparty to this option contract.
On September 15, 2008, Lehman Brothers Holdings Inc.  (Lehman) filed for protection under Chapter 11 of the United States Bankruptcy Code.
The bankruptcy filing of Lehman was an event of default that gave the company the right to immediately terminate the put option agreement with LBSF.
In March 2010, the company recognized a $6.0 million gain on derivative instruments as a result of a settlement from the Lehman bankruptcy proceedings.21.

SELECTED FINANCIAL DATA The following table includes certain financial information on a consolidated historical basis.

## Table 1 ##
As of December 31,
## Table 2 ##
(1) Property operating income is a non-GAAP measure that consists of rental income, other property income and mortgage interest income, less rental expenses and real estate taxes.
This measure is used internally to evaluate the performance of property operations and we consider it to be a significant measure.
Property operating income should not be considered an alternative measure of operating results or cash flow from operations as determined in accordance with GAAP.
REIT Qualification We intend to maintain our qualification as a REIT under Section 856(c) of the Code.
As a REIT, we generally will not be subject to corporate federal income taxes on income we distribute to our shareholders as long as we satisfy certain technical requirements of the Code, including the requirement to distribute at least 90% of our taxable income to our shareholders.
Funds From Operations Funds from operations (“FFO”) is a supplemental non-GAAP financial measure of real estate companies’ operating performance.
The National Association of Real Estate Investment Trusts (“NAREIT”) defines FFO as follows: net income, computed in accordance with U. S.  GAAP, plus real estate related depreciation and amortization and excluding extraordinary items and gains and losses on the sale of real estate, and impairment write-downs of depreciable real estate.
We compute FFO in accordance with the NAREIT definition, and we have historically reported our FFO available for common shareholders in addition to our net income and net cash provided by operating activities.
It should be noted that FFO: .
does not represent cash flows from operating activities in accordance with GAAP (which, unlike FFO, generally reflects all cash effects of transactions and other events in the determination of net income); .
should not be considered an alternative to net income as an indication of our performance; and .
is not necessarily indicative of cash flow as a measure of liquidity or ability to fund cash needs, including the payment of dividends.
We consider FFO available for common shareholders a meaningful, additional measure of operating performance primarily because it excludes the assumption that the value of the real estate assets diminishes predictably over time, as implied by the historical cost convention of GAAP and the recording of depreciation.
We use FFO primarily as one of several means of assessing our operating performance in comparison with other REITs.
Comparison of our presentation of FFO to similarly titled measures for other REITs may not necessarily be meaningful due to possible differences in the application of the NAREIT definition used by such REITs.
An increase or decrease in FFO available for common shareholders does not necessarily result in an increase or decrease in aggregate distributions because our Board of Trustees is not required to increase distributions on a quarterly basis unless necessary for us to maintain REIT status.
However, we must distribute at least 90% of our taxable income to remain qualified as a REIT.
Therefore, a significant increase in FFO will generally require an increase in distributions to shareholders although not necessarily on a proportionate basis.
The reconciliation of net income to FFO available for common shareholders is as follows:
## Table 3 ##
(1) For the year ended December 31, 2017, dividends on our Series 1 preferred stock are not deducted in the calculation of FFO available to common shareholders, as the related shares are dilutive and included in "weighted average common shares, diluted. "
The weighted average common shares used to compute FFO per diluted common share also includes
Future minimum lease payments and their present value for property under capital leases as of December 31, 2017, are as follows:

NOTE 6—FAIR VALUE OF FINANCIAL INSTRUMENTS A fair value measurement is based on the assumptions that market participants would use in pricing an asset or liability in an orderly transaction.
The hierarchy for inputs used in measuring fair value are as follows: 1.
Level 1 Inputs—quoted prices in active markets for identical assets or liabilities 2.
Level 2 Inputs—observable inputs other than quoted prices in active markets for identical assets and liabilities 3.
Level 3 Inputs—prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy.
In such cases, for disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement.
Except as disclosed below, the carrying amount of our financial instruments approximates their fair value.
The fair value of our mortgages payable, notes payable and senior notes and debentures is sensitive to fluctuations in interest rates.
Quoted market prices (Level 1) were used to estimate the fair value of our marketable senior notes and debentures and discounted cash flow analysis (Level 2) is generally used to estimate the fair value of our mortgages and notes payable.
Considerable judgment is necessary to estimate the fair value of financial instruments.
The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments.
A summary of the carrying amount and fair value of our mortgages payable, notes payable and senior notes and debentures is as follows:
