Derivative Instruments

The Company enters into derivative instruments for both risk management and investment purposes. The Company is exposed to potential loss from various market risks, and manages its market risks based on guidelines established by management and the Risk and Finance Committee of the Company's Board of Directors. The Company recognizes all derivatives as either assets or liabilities on the balance sheets and measures those instruments at fair value, with the changes in fair value of derivatives shown in the consolidated statement of income as "Net realized and unrealized gains (losses) on derivative instruments" unless the derivatives are designated as hedging instruments. The accounting for derivatives that are designated as hedging instruments is described in Note 2(h), "Significant Accounting Policies - Derivative Instruments." The following table summarizes information on the location and gross amounts of derivative fair values contained in the consolidated balance sheets at December 31, 2015 and 2014:

____________


(1)	Derivative instruments in an asset or liability position are included within Other assets or Other liabilities, respectively, in the balance sheets on a net basis where the Company has both a legal right of offset and the intention to settle the contracts on a net basis.

(2)

The fair value movements in derivative assets and liabilities relating to modified coinsurance funds withheld contracts are included within the associated asset or liability at each period end on the face of the balance sheets. Notional amounts associated with reinsurance agreements under which the Company assumes reinsurance risk are recorded as asset derivative notional amounts. Notional amounts associated with the GreyCastle Life Retro Arrangements under which the Company cedes reinsurance risk are recorded as liability derivative notional amounts. Included in the liability derivative notional amount at December 31, 2015 is the cumulative net realized and unrealized loss on life retrocession embedded derivative of $463.9 million.

The following table summarizes information on the gross and net amounts of derivative fair values and associated collateral received related to derivative assets, or collateral provided relating to derivative liabilities reported in other assets and other liabilities within the consolidated balance sheets at December 31, 2015 and 2014:



							Gross Amounts Not Offset in the Balance Sheets
December 31, 2015 (U.S. dollars in thousands)	Gross Amounts Recognized in the Balance Sheets		Gross Amounts Offset in the Balance Sheets		Net Amounts in the Balance Sheets		Financial Instruments		Cash Collateral		Net Amounts
Derivative Assets	$	89,314	$	3,087	$	86,227	$	—	$	30,958	$	55,269
Derivative Liabilities	$	45,495	$	3,087	$	42,408	$	—	$	—	$	42,408

December 31, 2014 (U.S. dollars in thousands)
Derivative Assets	$	136,659	$	696	$	135,963	$	—	$	78,580	$	57,383
Derivative Liabilities	$	31,184	$	696	$	30,488	$	—	$	—	$	30,488

Derivative instruments in an asset or liability position are included within Other assets or Other liabilities, respectively, on the balance sheets on a net basis where the Company has both a legal right of offset and the intention to settle the contracts on a net basis. The Company often enters into different types of derivative contracts with a single counterparty and these contracts are covered under netting agreements. At December 31, 2015 and 2014, the Company held cash collateral related to foreign currency derivative positions and certain other derivative positions of $31.0 million and $78.6 million, respectively. The assets and liabilities related to the net collateral paid or held were recorded as Other assets and Other liabilities, respectively, within the consolidated balance sheets as the collateral and derivative positions are not intended to be settled on a net basis.

(a) Derivative Instruments Designated as Fair Value Hedges

The Company designates certain of its derivative instruments as fair value hedges or cash flow hedges and formally and contemporaneously documents all relationships between the hedging instruments and hedged items and links the hedging derivative to specific assets and liabilities. The Company assesses the effectiveness of the hedge both at inception and on an on-going basis, and determines whether the hedge is highly effective in offsetting changes in fair value or cash flows of the linked hedged item.

The Company uses foreign exchange contracts to hedge the fair value of certain fixed income securities as well as to hedge certain net investments in foreign operations. In connection with the Catlin Acquisition and the FX Forwards, certain foreign exchange contracts utilized to hedge the fair value of certain net investments in foreign operations were de-designated as hedging instruments up until the time that the Catlin Acquisition was completed. Thereafter, these foreign exchange contracts were re-designated as hedging instruments. For the year ended December 31, 2015, there is no exposure to fair value hedges.

The following table provides the total impact on earnings relating to derivative instruments formally designated as fair value hedges along with the impacts of the related hedged items for the years indicated:



Derivatives Designated as Fair Value Hedges (U.S. dollars in thousands)	Hedged Items – Amount of Gain/(Loss) Recognized in Income Attributable to Risk
	Gain/(Loss) Recognized in Income on Derivative			Deposit Liabilities		Fixed Maturity Investments		Ineffective Portion of Hedging Relationship – Gain/(Loss)
Year Ended December 31, 2015
Interest rate exposure	$	—
Foreign exchange exposure	—
Total	$	—		$	—	$	—	$	—
Year Ended December 31, 2014
Interest rate exposure	$	—
Foreign exchange exposure	(15,663		)
Total	$	(15,663	)	$	—	$	15,407	$	(256	)

Interest rate exposure	$	—
Foreign exchange exposure	(22,568		)
Total	$	(22,568	)	$	—	$	23,065	$	497

The gains (losses) recorded on both the derivative instruments and specific items designated as being hedged as part of the fair value hedging relationships outlined above along with any associated ineffectiveness in the relationships are recorded through Net realized and unrealized gains (losses) on derivative instruments in the income statement.

Settlement of Fair Value Hedges

A summary of the fair value hedges that have been settled and their impact on results during the indicated years ended December 31 as well as the remaining balance of fair value hedges and average years remaining to maturity are shown below:



Settlement of Fair Value Hedges – Summary (U.S. dollars in thousands, except years)	Fair Value Hedges – Notes Payable and Debt December 31,				Fair Value Hedges – Deposit Liabilities December 31,
	2015		2014		2015		2014
Cumulative reduction to interest expense	$	—	$	21,624	$	103,742	$	95,333
Remaining balance	$	—	$	—	$	129,454	$	137,862
Weighted average years remaining to maturity	0.0		0.0		21.6		23.2

During the second quarter of 2014, the Company negotiated the termination of one of its larger structured indemnity contracts. This contract had previously been designated as a fair value hedge that was settled. The remaining fair value adjustment of $47.0 million that was being amortized as a reduction of interest expense over the remaining term of the contract was recorded as an adjustment to interest expense at the termination date. As a result of the termination, a net decrease of $28.7 million was recorded to interest expense reflecting the realization of the remaining balance of the fair value hedge adjustment, partially offset by an accretion rate adjustment due to changes in cash flows.

(b) Derivative Instruments Designated as Hedges of the Net Investment in a Foreign Operation

The Company utilizes foreign exchange contracts to hedge the fair value of certain net investments in foreign operations. During the year ended December 31, 2015 and 2014, the Company entered into foreign exchange contracts that were formally designated as hedges of investments in foreign subsidiaries, the majority of which have functional currencies of either U.K. sterling or the Euro. There was no ineffectiveness in these transactions.

The following table provides the weighted average U.S. dollar equivalent of foreign denominated net assets that were hedged and the resulting derivative gain (loss) that was recorded in the foreign currency translation adjustment, net of tax, account within AOCI for the years ended December 31, 2015 and 2014.



Derivative Instruments Designated as Hedges of the Net Investment in a Foreign Operation – Summary (U.S. dollars in thousands)	2015		2014
Weighted average of U.S. dollar equivalent of foreign denominated net assets	$	1,769,106	$	2,384,508
Derivative gains (losses) (1)	$	106,876	$	120,643

____________


(1)	Derivative gains (losses) from derivative instruments designated as hedges of the net investment in a foreign operation are recorded in the cumulative translation adjustment account within AOCI for each period.

The following table provides the total impact on earnings relating to derivative instruments not formally designated as hedging instruments under GAAP and from the ineffective portion of fair value hedges. The impacts are all recorded through Net realized and unrealized gains (losses) on derivatives in the income statement for the years ended December 31, 2015, 2014 and 2013:

The Company’s objectives in using these derivatives are explained below.

(c)(i) Investment Related Derivatives

The Company, either directly or through its investment managers, may use derivative instruments within its investment portfolio, including interest rate swaps, inflation swaps, commodity contracts, total return swaps, credit derivatives (single name and index credit default swaps), options, forward contracts and financial futures (foreign exchange, bond and stock index futures), primarily as a means of economically hedging exposures to interest rate, credit spread, equity price changes and foreign currency risk or, in limited instances, for efficient portfolio management. When using cleared (exchange traded) derivatives, the Company is exposed to the credit risk of the applicable clearing house and of the Company's future commissions merchant. When using uncleared (over-the-counter) derivatives, the Company is exposed to credit risk in the event of non-performance by the counterparties under any derivative contracts, although the Company generally seeks to use credit support arrangements with counterparties to help manage this risk.

Investment Related Derivatives – Interest Rate Exposure

The Company utilizes risk management and overlay strategies that incorporate the use of derivative financial instruments primarily to manage its fixed income portfolio duration and net economic exposure to interest rate risks. The Company may also use interest rate swaps to convert certain liabilities from a fixed rate to a variable rate of interest or use them to convert a variable rate of interest from one basis to another.

Investment Related Derivatives – Foreign Exchange Exposure

The Company has exposure to foreign currency exchange rate fluctuations through its operations and in its investment portfolio. The Company uses foreign exchange contracts to manage its exposure to the effects of fluctuating foreign currencies on the value of certain of its foreign currency fixed maturities. These contracts are not designated as specific hedges for financial reporting purposes and, therefore, realized and unrealized gains and losses on these contracts are recorded in income in the period in which they occur. These contracts generally have maturities of twelve months or less.

In addition, certain of the Company's investment managers may, subject to investment guidelines, enter into forward contracts.

Investment Related Derivatives – Credit Exposure

Credit derivatives may be purchased within the Company's investment portfolio in the form of single name and basket credit default swaps and swaptions, which are used to mitigate credit exposure through a reduction in credit spread duration (i.e., macro credit strategies rather than single-name credit hedging) or exposure to securities of selected issuers, including issuers that are not held in the underlying fixed income portfolio.

Investment Related Derivatives – Financial Market Exposure

Stock index futures may be purchased within the Company's investment portfolio in order to create synthetic equity exposure and to add value to the portfolio with overlay strategies where market inefficiencies are believed to exist. From time to time, the Company may enter into other financial market exposure derivative contracts on various indices including, but not limited to, inflation and commodity contracts.

(c)(ii) Financial Operations Derivatives – Credit Exposure

During the fourth quarter of 2014, the remaining financial operations credit derivative exposure, which was written as part of the Company's previous financial lines business and is outside of the Company's investment portfolio, was terminated. The Company has no continuing financial operations derivative credit exposures.

(c)(iii) Other Non-Investment Derivatives

Foreign Exchange Contracts

On January 9, 2015, the Company entered into the FX Forwards with Morgan Stanley Capital Services LLC and Goldman Sachs International. The purpose of the FX Forwards was to mitigate risk of foreign currency exposure related to the Catlin Acquisition. Following the closing of the Catlin Acquisition, the FX Forwards were settled.

In connection with the Catlin Acquisition and the FX Forwards, during the first quarter of 2015 certain foreign exchange contracts utilized to hedge the fair value of certain net investments in foreign operations were de-designated as hedging instruments; subsequently during the second quarter, the hedging relationships were then re-established.

In the fourth quarter of 2015, the Company entered into an average rate option to mitigate the risk of foreign currency exposure to certain GBP-denominated cash flows. The option will mature in the fourth quarter of 2016. Additionally, the Company has a small forward purchase to mitigate exposure to certain NZD-denominated cash flows.

Credit Exposure

During the year ended December 31, 2015, the Company entered into a non-investment-related credit derivative relating to a number of reference pool mortgage tranches associated with actual mortgage loans that were securitized into agency mortgage-backed securities and sold as Structured Agency Credit Risk Notes. At December 31, 2015, there was no reported event of default on this obligation. At December 31, 2015, the notional outstanding related to the derivative was $29.9 million and the Company had recorded a derivative asset of $0.03 million. During the year ended December 31, 2015, the Company recorded Net realized and unrealized gains of $0.1 million relating to this credit derivative. The credit derivative is recorded at fair value based upon models developed by the Company. Significant unobservable inputs considered in the valuation include the impact of changes in interest rates, future default, delinquency and prepayment rates, credit spreads, changes in credit quality, and other market factors.

Guaranteed Minimum Income Benefit Contract

The Company also has derivatives embedded in certain reinsurance contracts. For a certain life reinsurance contract, the Company pays the ceding company a fixed amount equal to the estimated present value of the excess of the guaranteed benefit over the account balance upon the policyholder's election to take the income benefit. The fair value of this derivative is determined based on the present value of expected cash flows.

Modified Coinsurance and Funds Withheld Contracts

The Company has modified coinsurance and funds withheld reinsurance agreements that provide for a return to be paid to the Company based on a portfolio of fixed income securities. As such, the agreements contain an embedded derivative. The embedded derivative is bifurcated from the funds withheld balance and recorded at fair value with changes in fair value recognized in earnings through Net realized and unrealized gains (losses) on derivative instruments.

Modified Coinsurance Funds Withheld Reinsurance Agreements - Life Retrocession Embedded Derivative

In addition, the Company has entered into the GreyCastle Life Retro Arrangements as described in Note 2(c), "Significant Accounting Policies - Total Investments - Investments Related to Life Retrocession Arrangements written on a Funds Withheld Basis," "Note 2(e), "Significant Accounting Policies - Reinsurance," and Note 3(e), "Acquisitions and Disposals - Sale of Life Reinsurance Subsidiary." The embedded derivative related to the GreyCastle Life Retro Arrangements is recorded at fair value with changes in fair value recognized in earnings through Net realized and unrealized gains (losses) on life retrocession embedded derivative and derivative instruments - Life Funds Withheld Assets.

The change in the value of the life retrocession embedded derivative includes the interest income, realized and unrealized gains and losses on Life Funds Withheld Assets and certain related expenses subsequent to May 30, 2014 as follows:



Components of Life Retrocession Embedded Derivative and Derivative Instruments - Life Funds Withheld Assets:
(U.S. dollars in thousands)	2015			2014
Interest income - Life Funds Withheld Assets	$	(193,568	)	$	(134,634	)

Net realized and unrealized gains (losses) on life retrocession embedded derivative and derivative instruments - Life Funds Withheld Assets	$	(151,691	)	$	(488,222	)

(d) Contingent Credit Features

Certain derivative agreements entered into by the Company or its subsidiaries contain credit rating downgrade provisions that permit early termination of the agreements by the counterparty if collateral is not posted following failure to maintain certain credit ratings from one or more of the principal credit rating agencies. If the Company were required to terminate such agreements early due to a credit rating downgrade, it could potentially be in a net liability position at the time of settlement of such agreements. The aggregate fair value of all derivative agreements containing such rating downgrade provisions that were in a liability position and any collateral posted under these agreements at December 31 for the years indicated were as follows:



Contingent Credit Features - Summary: (U.S. dollars in thousands)	2015		2014
Aggregate fair value of derivative agreements with downgrade provisions in a net liability position	$	5,827	$	5,770
Collateral posted to counterparty	$	—	$	—
