DERIVATIVE FINANCIAL INSTRUMENTS:

The Company actively monitors its exposure to interest rate and foreign currency exchange rate risks and uses derivative financial instruments to manage the impact of certain of these risks. The Company uses derivatives only for purposes of managing risk associated with underlying exposures. The Company does not trade or use instruments with the objective of earning financial gains on the interest rate or exchange rate fluctuations alone, nor does the Company use derivative instruments where it does not have underlying exposures. Complex instruments involving leverage or multipliers are not used. The Company manages its hedging position and monitors the credit ratings of counterparties and does not anticipate losses due to counterparty nonperformance. Management believes its use of derivative instruments to manage risk is in the Company’s best interest. However, the Company’s use of derivative financial instruments may result in short-term gains or losses and increased earnings volatility. The Company’s instruments are recorded in the consolidated balance sheets at fair value in prepaid expenses and other, other assets, net, accrued expenses or other long-term liabilities.

The Company may designate derivatives as a hedge of a forecasted transaction or a hedge of the variability of the cash flows to be received or paid in the future related to a recognized asset or liability (cash flow hedge). The portion of the changes in the fair value of the derivative used as a cash flow hedge that is offset by changes in the expected cash flows related to a recognized asset or liability (the effective portion) is recorded in other comprehensive income. As the hedged item is realized, the gain or loss included in accumulated other comprehensive income is reported in the consolidated statements of operations on the same line item as the hedged item. The portion of the changes in the fair value of derivatives used as cash flow hedges that is not offset by changes in the expected cash flows related to a recognized asset or liability (the ineffective portion) is immediately recognized in earnings on the same line item as the hedged item.

The Company matches the hedge instrument to the underlying hedged item (assets, liabilities, firm commitments or forecasted transactions). At inception of the hedge and at least quarterly thereafter, the Company assesses whether the derivatives used to hedge transactions are highly effective in offsetting changes in either the fair value or cash flows of the hedged item. When it is determined that a derivative ceases to be a highly effective hedge, the Company discontinues hedge accounting, and any gains or losses on the derivative instrument thereafter are recognized in earnings during the periods it no longer qualifies as a hedge.

From time to time, the Company may enter into certain derivative instruments that may not be designated as hedges for accounting purposes. For example, to mitigate currency exposures related to intercompany debt, cross-currency swap contracts may be entered into for periods consistent with the underlying debt. The Company believes such instruments are closely correlated with the underlying exposure, thus reducing the associated risk. The gains or losses from the changes in the fair value of derivative instruments not accounted for as hedges are recognized in current period earnings within other income, net.

Interest Rate Risk Management

The Company uses interest rate swap agreements to manage its exposure to changes in interest rates of the Company’s variable rate debt. These swap agreements are recorded in the consolidated balance sheets at fair value. Changes in the fair value of the swap agreements are recorded in net income or other comprehensive income/(loss), based on whether the agreements are designated as part of a hedge transaction and whether the agreements are effective in offsetting the change in the value of the future interest payments attributable to the underlying portion of the Company’s variable rate debt. Interest payments accrued each reporting period for these interest rate swaps are recognized in interest expense. The Company formally documents its hedge relationships, including identifying the hedge instruments and hedged items, as well as its risk management objectives and strategies for entering into the hedge transaction.

The following table summarizes the terms of the Company's outstanding interest rate swap agreements entered into to manage the Company's exposure to changes in interest rates on its variable rate debt (dollars in thousands):



		Notional Amount

9/30/2016	9/30/2026	9/30/2026	$	100,000	2.79%	3-month LIBOR
9/30/2016	9/30/2026	9/30/2026	$	100,000	2.79%	3-month LIBOR
9/30/2016	9/30/2026	9/30/2026	$	100,000	2.80%	3-month LIBOR

On November 9, 2012, the Company entered into multiple 10-year forward starting interest rate swap agreements to manage the exposure to changes in interest rates on the Company's variable rate debt. On the date of the hedge designation, September 30, 2016, it is probable that the Company will either issue $300.0 million of fixed-rate debt or have $300.0 million of variable-rate debt under the Company's commercial banking lines. The forward starting interest swap agreements are expected to settle in cash on September 30, 2016. The Company expects any gains or losses on settlement will be amortized over the life of the respective swaps.

The following table summarizes the Company's interest rate swap agreements that expired during 2013 (dollars in thousands):



		Notional Amount
Effective Date	Expiration Date	Date	Amount		Paid Fixed Rate	Receive Variable Rate
10/6/2008	9/30/2013	10/6/2008	$	120,000	3.88%	1-month LIBOR
10/4/2012	9/30/2013	10/4/2012	$	1,450,000	0.25%	1-month LIBOR
		1/1/2013	$	1,350,000	0.25%	1-month LIBOR
		4/1/2013	$	1,300,000	0.25%	1-month LIBOR
		7/1/2013	$	1,250,000	0.25%	1-month LIBOR

The fair value of the interest rate swap agreements were estimated based on Level 2 inputs. The Company’s effectiveness testing during the year ended December 31, 2013 resulted in no amount of gain or loss reclassified from accumulated other comprehensive income/(loss) into earnings due to ineffectiveness. During the year ended December 31, 2013, $4.1 million of net losses were realized and recorded as interest expense in the consolidated statement of operations. Based on the Company's fair value assumptions as of December 31, 2013, it expects to realize $1.6 million of net losses that are reported in accumulated other comprehensive income into earnings within the next 12 months. See Note 16, Accumulated Other Comprehensive Income, for additional information regarding the Company's cash flow hedges.

Foreign Currency Exchange Rate Risk

As of December 31, 2013, $142.1 million of third-party debt related to the Company’s foreign operations was denominated in the currencies in which its subsidiaries operate, including the Australian dollar, Canadian dollar and Euro. The debt service obligations associated with this foreign currency debt are generally funded directly from those operations. As a result, foreign currency risk related to this portion of the Company’s debt service payments is limited. However, in the event the foreign currency debt service is not paid from the Company's foreign operations, the Company may face exchange rate risk if the Australian or Canadian dollar or Euro were to appreciate relative to the United States dollar and require higher United States dollar equivalent cash.

The Company is also exposed to foreign currency exchange rate risk related to its foreign operations, including non-functional currency intercompany debt, typically from the Company’s United States operations to its foreign subsidiaries, and any timing difference between announcement and closing of an acquisition of a foreign business to the extent such acquisition is funded with United States dollars. To mitigate currency exposures related to non-functional currency denominated intercompany debt, cross-currency swap contracts may be entered into for periods consistent with the underlying debt. In determining the fair value of the derivative contract, the significant inputs to valuation models are quoted market prices of similar instruments in active markets. To mitigate currency exposures of non-United States dollar denominated acquisitions, the Company may enter into foreign exchange forward contracts. Although these derivative contracts do not qualify for hedge accounting, the Company believes that such instruments are closely correlated with the underlying exposure, thus reducing the associated risk. The gains or losses from changes in the fair value of derivative instruments that are not accounted for as hedges are recognized in current period earnings within other income, net.

To mitigate the foreign currency exchange rate risk related to a non-functional currency intercompany loan between the United States and Australian entities, the Company entered into an Australian dollar/United States dollar floating to floating cross-currency swap agreement (the Swap), effective as of December 1, 2010, which effectively converted the A$105.0 million intercompany loan receivable in the United States into a $100.6 million loan receivable. As a result of the quarterly net settlement payments associated with this swap, the Company realized a net expense of $4.4 million within interest (expense)/income for the year ended December 31, 2012. In addition, the Company recognized $0.6 million within other income, net related to the settlement of the derivative agreement and the underlying intercompany debt instrument to the exchange rate for the year ended December 31, 2012. The Swap expired on December 1, 2012 and was settled for $9.1 million.

On November 29, 2012, simultaneous with the termination of the previous swap, the Company entered into two new 2-year Australian dollar/United States dollar floating to floating cross-currency swap agreements (the Swaps), effective December 3, 2012. These agreements expire on December 1, 2014. The Swaps effectively convert the A$105.0 million intercompany loan receivable in the United States into a $109.6 million loan receivable. The Swaps require the Company to pay Australian dollar BBSW plus 3.25% based on a notional amount of A$105.0 million and allow the Company to receive United States LIBOR plus 2.82% based on a notional amount of $109.6 million on a quarterly basis. BBSW is the wholesale interbank reference rate within Australia, which we believe is generally considered the Australian equivalent to LIBOR. As a result of these quarterly net settlement payments, the Company realized a net expense of $2.7 million within interest (expense)/income for the year ended December 31, 2013. In addition, the Company recognized $0.4 million within other income, net related to the settlement of the derivative agreement and the underlying intercompany debt instrument to the exchange rate for the year ended December 31, 2013.

Contingent Forward Sale Contract

In conjunction with the Company's announcement on July 23, 2012 of its plan to acquire RailAmerica, the Company entered into the Investment Agreement with Carlyle in order to partially fund the acquisition of RailAmerica. Pursuant to the Investment Agreement, Carlyle agreed to purchase a minimum of $350.0 million of Series A-1 Preferred Stock, which Series A-1 Preferred Stock was convertible into the Company's Class A common stock in certain circumstances. The conversion price of the Series A-1 Preferred Stock was set at approximately $58.49, which was a 4.5% premium to the Company's stock price on the trading day prior to the announcement of the RailAmerica acquisition. For the period between July 23, 2012 and September 30, 2012, this instrument was accounted for as a contingent forward sale contract with mark-to-market non-cash income or expense included in the Company's consolidated financial results and the cumulative effect represented as an asset or liability. The closing price of the Company's Class A common stock was $66.86 on September 28, 2012, which was the last trading day prior to issuing the Series A-1 Preferred Stock, and, accordingly, the Company recorded a $50.1 million non-cash mark-to-market expense related to the Investment Agreement for the year ended December 31, 2012. As discussed in Note 4, Earnings Per Common Share, the Company converted the Series A-1 Preferred Stock into Class A common stock on February 13, 2013.

The Company's derivative instruments are subject to master netting arrangements between the Company and the respective counterparty. The Company presents its derivative instruments on a gross basis. As of December 31, 2013 and 2012, the differences between the gross values and net values under such master netting arrangements were not significant. The following table summarizes the fair value of derivative instruments recorded in the consolidated balance sheets as of December 31, 2013 and 2012 (dollars in thousands):
