Cautionary Statement Regarding Forward-Looking Statements

The Private Securities Litigation Reform Act of 1995 (the Act) provides a "safe harbor" to encourage companies to provide prospective information, as long as those statements are identified as forward-looking and are accompanied by meaningful cautionary statements identifying important factors that could cause actual results to differ materially from those included in the forward-looking statements. Certain information contained in this Quarterly Report on Form 10-Q (including certain statements in the consolidated financial statements and related notes and Management's Discussion and Analysis), or in any other written or oral statements made by us in communications with the financial community or contained in documents filed with the Securities and Exchange Commission (SEC), may be considered forward-looking statements within the meaning of the Act. Forward-looking statements are those not based on historical information, but rather relate to our outlook, future operations, strategies, financial results, or other developments. Forward-looking statements speak only as of the date made. We undertake no obligation to update these statements, even if made available on our website or otherwise. These statements may be made directly in this document or may be made part of this document by reference to other documents filed by us with the SEC, a practice which is known as "incorporation by reference." You can find many of these statements by looking for words such as "will," "may," "should," "could," "believes," "expects," "anticipates," "estimates," "plans," "assumes," "intends," "projects," "goals,” "objectives," or similar expressions in this document or in documents incorporated herein.

These forward-looking statements are subject to numerous assumptions, risks, and uncertainties, many of which are beyond our control. We caution readers that the following factors, in addition to other factors mentioned from time to time, may cause actual results to differ materially from those contemplated by the forward-looking statements:

• Sustained periods of low interest rates.

• Fluctuation in insurance reserve liabilities and claim payments due to changes in claim incidence, recovery rates, mortality and morbidity rates, and policy benefit offsets due to, among other factors, the rate of unemployment and consumer confidence, the emergence of new diseases, epidemics, or pandemics, new trends and developments in medical treatments, the effectiveness of our claims operational processes, and changes in governmental programs.

• Unfavorable economic or business conditions, both domestic and foreign, that may result in decreases in sales, premiums, or persistency, as well as unfavorable claims activity.

• Changes in or interpretations of laws and regulations, including tax laws and regulations.

• A cyber attack or other security breach could result in the unauthorized acquisition of confidential data.

• The failure of our business recovery and incident management processes to resume our business operations in the event of a natural catastrophe, cyber attack, or other event.

• Investment results, including, but not limited to, changes in interest rates, defaults, changes in credit spreads, impairments, and the lack of appropriate investments in the market which can be acquired to match our liabilities.

• Increased competition from other insurers and financial services companies due to industry consolidation, new entrants to our markets, or other factors.

• Changes in our financial strength and credit ratings.

• Our ability to execute on our technology systems upgrades or replacements.

• Damage to our reputation due to, among other factors, regulatory investigations, legal proceedings, external events, and/or inadequate or failed internal controls and procedures.

• Actual experience in the broad array of our products that deviates from our assumptions used in pricing, underwriting, and reserving.

• Changes in accounting standards, practices, or policies.

• Effectiveness of our risk management program.

• Contingencies and the level and results of litigation.

• Availability of reinsurance in the market and the ability of our reinsurers to meet their obligations to us.

• Ineffectiveness of our derivatives hedging programs due to changes in the economic environment, counterparty risk, ratings downgrades, capital market volatility, changes in interest rates, and/or regulation.

• Fluctuation in foreign currency exchange rates.

• Ability to generate sufficient internal liquidity and/or obtain external financing.

• Recoverability and/or realization of the carrying value of our intangible assets, long-lived assets, and deferred tax assets.

• Terrorism, both within the U.S. and abroad, ongoing military actions, and heightened security measures in response to these types of threats.

1

For further discussion of risks and uncertainties which could cause actual results to differ from those contained in the forward-looking statements, see Part 1, Item 1A of our annual report on Form 10-K for the year ended December 31, 2018.

All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Unum Group and Subsidiaries

June 30, 2019

Note 1 - Basis of Presentation

The accompanying consolidated financial statements of Unum Group and its subsidiaries (the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes included in our annual report on Form 10-K for the year ended December 31, 2018.

In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Interim results are not necessarily indicative of full year performance.

Note 2 - Accounting Developments

Accounting Updates Adopted in 2019:

Accounting Standards Codification (ASC)	Description	Date of Adoption	Effect on Financial Statements
ASC 220 "Income Statement - Reporting Comprehensive Income"	This update allowed entities to make an accounting policy election to reclassify the disproportionate tax effects arising as a result of the recognition of the enactment of the tax bill, H.R.1, An Act to Provide Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018, more commonly known as the Tax Cuts and Jobs Act (TCJA) from accumulated other comprehensive income to retained earnings. Tax effects that are disproportionate in accumulated other comprehensive income for reasons other than the TCJA may not be reclassified. This update required additional disclosures on whether an entity elects to reclassify the disproportionate tax effects and its policy for releasing tax effects from accumulated other comprehensive income. This guidance was applied in the period of adoption.	January 1, 2019	The adoption of this update expanded certain of our disclosures but had no impact on our financial position or results of operations because we did not make the optional accounting policy election to reclassify the disproportionate tax effects resulting from the TCJA from accumulated other comprehensive income to retained earnings. We use an aggregate portfolio approach to release disproportionate tax effects when disposing of an entire business segment’s portfolio.
ASC 310 "Receivables - Nonrefundable Fees and Other Costs"	This update shortened the amortization period to the earliest call date for certain callable debt securities held at a premium. This update did not impact securities held at a discount. The guidance was applied in the period of adoption.	January 1, 2019	The adoption of this update did not have a material impact on our financial position or results of operations.
ASC 718 "Compensation - Stock Compensation"	This update generally aligned the accounting guidance for share-based payments issued to non-employees with guidance for share-based payments issued to employees. Specifically, the update required non-employee share-based payments to be measured using the grant date fair value of the equity instruments that an entity is obligated to issue when the good has been delivered or the service has been rendered rather than being remeasured through the performance completion date. Additionally, for non-employee share-based payments that contain performance conditions, the update changed the criteria regarding the recognition of compensation cost to when achievement of a performance condition is probable rather than upon actual achievement of the performance condition. The guidance was applied in the period of adoption.	January 1, 2019	The adoption of this update did not have an impact on our financial position or results of operations.

Note 2 - Accounting Developments - Continued

ASC	Description	Date of Adoption	Effect on Financial Statements
ASC 842 "Leases"	This update changed the accounting for leases, requiring lessees to report most leases on their balance sheets, regardless of whether the lease is classified as a finance lease or an operating lease. For lessees, the initial lease liability is equal to the present value of lease payments, and a corresponding asset, adjusted for certain items, is also recorded. Expense recognition for lessees remained similar to previous accounting requirements for capital and operating leases. For lessors, the guidance modified the classification criteria and the accounting for sales-type and direct financing leases. The guidance was applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings at the beginning of the period of adoption. In addition, the package of practical expedients available to leases that commenced prior to the date of adoption was applied.	January 1, 2019	See the summary table below for the financial statement impacts of this modified retrospective adoption on our financial statement line items at January 1, 2019. In addition, see Note 12 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 for the additional disclosures required by the update.

Summary of Financial Statement Impacts of Accounting Updates adopted in 2018:

Effective January 1, 2018, we adopted an update under ASC 825 that changed the accounting and disclosure requirements for certain financial instruments. These changes included a requirement to measure equity investments, other than those that resulted in consolidation or are accounted for under the equity method, at fair value through net income unless the investment qualifies for certain practicability exceptions. The guidance was applied using a modified retrospective approach through a cumulative-effect reduction to accumulated other comprehensive income of $17.5 million with a corresponding increase to retained earnings of $14.5 million, a decrease to other long-term investments of $3.8 million, and a decrease to deferred income tax liability of $0.8 million.

Note 2 - Accounting Developments - Continued

Accounting Updates Outstanding:

ASC	Description	Date of Adoption	Effect on Financial Statements
ASC 326 "Financial Instruments - Credit Losses"	This update amends the guidance on the impairment of financial instruments. The update adds an impairment model known as the current expected credit loss model that is based on expected losses rather than incurred losses and will generally result in earlier recognition of allowances for losses. The current expected credit loss model applies to financial instruments such as mortgage loans, fixed maturity securities classified as held-to-maturity, and certain receivables. The update also modifies the other-than-temporary impairment model used for available-for-sale fixed maturity securities such that credit losses are recognized as an allowance rather than as a reduction in the amortized cost of the security. The reversal of previously recognized credit losses on available-for-sale fixed maturity securities is allowed under specified circumstances. Additional disclosures will also be required, including information used to develop the allowance for losses. The guidance is to be applied to most instruments in scope using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. For available-for-sale fixed maturity securities, the update is applied prospectively. Other-than-temporary impairment losses recognized on available-for-sale fixed maturity securities prior to adoption of the update cannot be reversed. Early adoption is permitted.	January 1, 2020	We have determined that this guidance is primarily applicable to our mortgage loan investments and reinsurance recoverables. We are currently developing and implementing systems to support the expected credit loss projections for these asset types. We continue to evaluate the expected impact on our financial position, results of operations, and disclosures.
ASC 350 "Intangibles - Goodwill and Other"	This update eliminates the requirement to calculate the implied fair value of goodwill (the second step in the current two-step test) to measure a goodwill impairment charge. Instead, entities should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the excess of the carrying amount over the fair value, with the loss not to exceed the total amount of goodwill allocated to that reporting unit. The guidance is to be applied prospectively, with early adoption permitted for goodwill impairment tests performed on testing dates after January 1, 2017.	January 1, 2020	The adoption of this update will not have a material effect on our financial position or results of operations.

ASC 820 "Fair Value Measurement"	This update amended the fair value measurement guidance by removing or clarifying certain existing disclosure requirements, while also adding new disclosure requirements. Specifically, this update removed certain disclosures related to Level 1 and Level 2 transfers and also removed the discussion regarding valuation processes of Level 3 fair value measurements. The update modifies guidance related to investments in certain entities that calculate net asset value to explicitly require disclosure regarding timing of liquidation of the investee's assets and timing of redemption restrictions. The update adds disclosures around the changes in unrealized gains and losses in other comprehensive income for recurring Level 3 investments held at the end of the reporting period and adds disclosures regarding certain unobservable inputs on Level 3 fair value measurements. The guidance was applied retrospectively or prospectively depending on the specific requirement of the update. Entities are permitted to early adopt any removed or modified disclosures and may delay adoption of the additional disclosures until their effective date.	December 31, 2018 for the removal and modification of certain disclosures and January 1, 2020 for the addition of certain disclosures.	We elected to early adopt the removal and modification of disclosures, as permitted by the update. We have elected to delay the adoption of the additional disclosures until the effective date. The adoption of this update will modify our disclosures but will not have an impact on our financial position or results of operations.

ASC 944 "Financial Services - Insurance"	This update significantly amends the accounting and disclosure requirements for long-duration insurance contracts. These changes include a requirement to review, and if necessary, update cash flow assumptions used to measure the liability for future policy benefits for traditional and limited-payment contracts at least annually, with changes recognized in earnings. In addition, an entity will be required to update the discount rate assumption at each reporting date using a yield that is reflective of an upper-medium grade fixed-income instrument, with changes recognized in other comprehensive income. These changes result in the elimination of the provision for risk of adverse deviation and premium deficiency (or loss recognition) testing. The update also requires that an entity measure all market risk benefits associated with deposit contracts at fair value, with changes recognized in earnings except for the portion attributable to a change in the instrument-specific credit risk, which is to be recognized in other comprehensive income. This update also simplifies the amortization of deferred acquisition costs by requiring amortization on a constant level basis over the expected term of the related contracts. Deferred acquisition costs are required to be written off for unexpected contract terminations but are no longer subject to an impairment test. Significant additional disclosures will also be required, which include disaggregated rollforwards of certain liability balances and the disclosure of qualitative and quantitative information about expected cash flows, estimates, and assumptions. The application of this guidance will vary based upon the specific requirements of the update but will generally result in either a modified retrospective or full retrospective approach with changes applied as of the beginning of the earliest period presented. Early adoption is permitted. * In July 2019, the Financial Accounting Standards Board (FASB) voted to propose a one-year deferral of the effective date to January 1, 2022. The FASB is expected to issue a final amendment later in 2019 regarding the proposed deferral date.	January 1, 2021*	We are currently evaluating the impact of the update and expect that the adoption may have a material impact on our financial position and results of operations. The update will also significantly expand our disclosures.

Note 3 - Fair Values of Financial Instruments

Fair Value Measurements for Financial Instruments Carried at Fair Value

We report fixed maturity securities, which are classified as available-for-sale securities, derivative financial instruments, and unrestricted equity securities at fair value in our consolidated balance sheets. We report our investments in private equity partnerships at our share of the partnerships' net asset value per share or its equivalent (NAV) as a practical expedient for fair value.

The degree of judgment utilized in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and less judgment utilized in measuring fair value. An active market for a financial instrument is a market in which transactions for an asset or a similar asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and should be used to measure fair value whenever available. Conversely, financial instruments rarely traded or not quoted have less observability and are measured at fair value using valuation techniques that require more judgment. Pricing observability is generally impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, and overall market conditions.

We classify financial instruments in accordance with a fair value hierarchy consisting of three levels based on the observability of valuation inputs:

• Level 1 - the highest category of the fair value hierarchy classification wherein inputs are unadjusted and represent quoted prices in active markets for identical assets or liabilities at the measurement date.

• Level 2 - valued using inputs (other than prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument's anticipated life.

• Level 3 - the lowest category of the fair value hierarchy and reflects the judgment of management regarding what market participants would use in pricing assets or liabilities at the measurement date. Financial assets and liabilities categorized as Level 3 are generally those that are valued using unobservable inputs to extrapolate an estimated fair value.

Valuation Methodologies of Financial Instruments Measured at Fair Value

Valuation techniques used for assets and liabilities accounted for at fair value are generally categorized into three types. The market approach uses prices and other relevant information from market transactions involving identical or comparable assets or liabilities. The income approach converts future amounts, such as cash flows or earnings, to a single present amount, or a discounted amount. The cost approach is based upon the amount that currently would be required to replace the service capacity of an asset, or the current replacement cost.

We use valuation techniques that are appropriate in the circumstances and for which sufficient data are available that can be obtained without undue cost and effort. In some cases, a single valuation technique will be appropriate (for example, when valuing an asset or liability using quoted prices in an active market for identical assets or liabilities). In other cases, multiple valuation techniques will be appropriate. If we use multiple valuation techniques to measure fair value, we evaluate and weigh the results, as appropriate, considering the reasonableness of the range indicated by those results. A fair value measurement is the point within that range that is most representative of fair value in the circumstances.

Note 3 - Fair Values of Financial Instruments - Continued

The selection of the valuation method(s) to apply considers the definition of an exit price and depends on the nature of the asset or liability being valued. For assets and liabilities accounted for at fair value, we generally use valuation techniques consistent with the market approach, and to a lesser extent, the income approach. We believe the market approach provides more observable data than the income approach, considering the type of investments we hold. Our fair value measurements could differ significantly based on the valuation technique and available inputs. When using a pricing service, we obtain the vendor's pricing documentation to ensure we understand their methodologies. We periodically review and approve the selection of our pricing vendors to ensure we are in agreement with their current methodologies. When markets are less active, brokers may rely more on models with inputs based on the information available only to the broker. Our internal investment management professionals, which include portfolio managers and analysts, monitor securities priced by brokers and evaluate their prices for reasonableness based on benchmarking to available primary and secondary market information. In weighing a broker quote as an input to fair value, we place less reliance on quotes that do not reflect the result of market transactions. We also consider the nature of the quote, particularly whether the quote is a binding offer. If prices in an inactive market do not reflect current prices for the same or similar assets, adjustments may be necessary to arrive at fair value. When relevant market data is unavailable, which may be the case during periods of market uncertainty, the income approach can, in suitable circumstances, provide a more appropriate fair value. During 2019, we have applied valuation approaches and techniques on a consistent basis to similar assets and liabilities and consistent with those approaches and techniques used at year end 2018.

Fixed Maturity and Equity Securities

We use observable and unobservable inputs in measuring the fair value of our fixed maturity and equity securities. For securities categorized as Level 1, fair values equal active Trade Reporting and Compliance Engine (TRACE) pricing or unadjusted broker market maker prices. For securities categorized as Level 2 or Level 3, inputs that may be used in valuing each class of securities at any given time period are disclosed below. Actual inputs used to determine fair values will vary for each reporting period depending on the availability of inputs which may, at times, be affected by the lack of market liquidity.

Note 3 - Fair Values of Financial Instruments - Continued

The management of our investment portfolio includes establishing pricing policy and reviewing the reasonableness of sources and inputs used in developing pricing. We review all prices obtained to ensure they are consistent with a variety of observable market inputs and to verify the validity of a security's price.  In the event we receive a vendor's market price that does not appear reasonable based on our market analysis, we may challenge the price and request further information about the assumptions and methodologies used by the vendor to price the security. We may change the vendor price based on a better data source such as an actual trade. We also review all price changes from the prior month which fall outside a predetermined corridor. The overall valuation process for determining fair values may include adjustments to valuations obtained from our pricing sources when they do not represent a valid exit price. These adjustments may be made when, in our judgment and considering our knowledge of the financial conditions and industry in which the issuer operates, certain features of the financial instrument require that an adjustment be made to the value originally obtained from our pricing sources. These features may include the complexity of the financial instrument, the market in which the financial instrument is traded, counterparty credit risk, credit structure, concentration, or liquidity. Additionally, an adjustment to the price derived from a model typically reflects our judgment of the inputs that other participants in the market for the financial instrument being measured at fair value would consider in pricing that same financial instrument. In the event an asset is sold, we test the validity of the fair value determined by our valuation techniques by comparing the selling price to the fair value determined for the asset in the immediately preceding month end reporting period.

Certain of our investments do not have readily determinable market prices and/or observable inputs or may at times be affected by the lack of market liquidity. For these securities, we use internally prepared valuations combining matrix pricing with vendor purchased software programs, including valuations based on estimates of future profitability, to estimate the fair value. Additionally, we may obtain prices from independent third-party brokers to aid in establishing valuations for certain of these securities. Key assumptions used by us to determine fair value for these securities include risk free interest rates, risk premiums, performance of underlying collateral (if any), and other factors involving significant assumptions which may or may not reflect those of an active market.

The parameters and inputs used to validate a price on a security may be adjusted for assumptions about risk and current market conditions on a quarter to quarter basis, as certain features may be more significant drivers of valuation at the time of pricing. Changes to inputs in valuations are not changes to valuation methodologies; rather, the inputs are modified to reflect direct or indirect impacts on asset classes from changes in market conditions.

At June 30, 2019, 23.6 percent of our fixed maturity securities were valued using active trades from TRACE pricing or broker market maker prices for which there was current market activity in that specific security (comparable to receiving one binding quote).  The prices obtained were not adjusted, and the assets were classified as Level 1.

The remaining 76.4 percent of our fixed maturity securities were valued based on non-binding quotes or other observable and unobservable inputs, as discussed below:

• 63.1 percent of our fixed maturity securities were valued based on prices from pricing services that generally use observable inputs such as prices for securities or comparable securities in active markets in their valuation techniques. These assets were classified as Level 2. 

• 3.7 percent of our fixed maturity securities were valued based on one or more non-binding broker quotes, if validated by observable market data, or on TRACE prices for identical or similar assets absent current market activity. When only one price is available, it is used if observable inputs and analysis confirms that it is appropriate. These assets, for which we were able to validate the price using other observable market data, were classified as Level 2.

• 9.6 percent of our fixed maturity securities were valued based on prices of comparable securities, matrix pricing, market models, and/or internal models or were valued based on non-binding quotes with no other observable market data. These assets were classified as either Level 2 or Level 3, with the categorization dependent on whether there was other observable market data.

Derivatives

Fair values for derivatives other than embedded derivatives in modified coinsurance arrangements are based on market quotes or pricing models and represent the net amount of cash we would have paid or received if the contracts had been settled or closed as of the last day of the period. We analyze credit default swap spreads relative to the average credit spread embedded within the LIBOR-setting syndicate in determining the effect of credit risk on our derivatives' fair values.  If net counterparty credit risk for a derivative asset is determined to be material and is not adequately reflected in the LIBOR-based fair value obtained from our pricing sources, we adjust the valuations obtained from our pricing sources. For purposes of valuing net counterparty risk, we measure the fair value of a group of financial assets and financial liabilities on the basis of the price that would be received to sell a net long position or transfer a net short position for a particular risk exposure in an orderly transaction between market participants at the measurement date under current market conditions. In regard to our own credit risk component, we adjust the valuation of derivative liabilities wherein the counterparty is exposed to our credit risk when the LIBOR-based valuation of our derivatives obtained from pricing sources does not effectively include an adequate credit component for our own credit risk.

Fair values for our embedded derivative in a modified coinsurance arrangement are estimated using internal pricing models and represent the hypothetical value of the duration mismatch of assets and liabilities, interest rate risk, and third party credit risk embedded in the modified coinsurance arrangement.

We consider transactions in inactive markets to be less representative of fair value. We use all available observable inputs when measuring fair value, but when significant unobservable inputs are used, we classify these assets or liabilities as Level 3.

Private Equity Partnerships

Our private equity partnerships represent funds that are primarily invested in private credit, private equity, and real assets, as described below. Distributions received from the funds arise from income generated by the underlying investments as well as the liquidation of the underlying investments. There is generally not a public market for these investments.

Note 3 - Fair Values of Financial Instruments - Continued

Realized and unrealized investment gains and losses presented in the preceding tables represent gains and losses only for the time during which the applicable financial instruments were classified as Level 3. The transfers between levels resulted primarily from a change in observability of three inputs used to determine fair values of the securities transferred: (1) transactional data for new issuance and secondary trades, (2) broker/dealer quotes and pricing, primarily related to changes in the level of activity in the market and whether the market was considered orderly, and (3) comparable bond metrics from which to perform an analysis. For fair value measurements of financial instruments that were transferred either into or out of Level 3, we reflect the transfers using the fair value at the beginning of the period. We believe this allows for greater transparency, as all changes in fair value that arise during the reporting period of the transfer are disclosed as a component of our Level 3 reconciliation. Gains (losses) which are included in earnings and are attributable to the change in fair value of assets or liabilities valued using significant unobservable inputs and still held at period end were $(0.8) million and $4.7 million for the three and six months ended June 30, 2019, respectively, and $(2.3) million and $(4.0) million for the three and six months ended June 30, 2018, respectively. These amounts relate entirely to the change in fair value of an embedded derivative in a modified coinsurance arrangement and are reported as a component of realized investment gains and losses.

The table below provides quantitative information regarding the significant unobservable inputs used in Level 3 fair value measurements derived from internal models. Certain securities classified as Level 3 are excluded from the table below due to limitations in our ability to obtain the underlying inputs used by external pricing sources.

Note 3 - Fair Values of Financial Instruments - Continued

Isolated increases in unobservable inputs other than market convention will result in a lower fair value measurement, whereas isolated decreases will result in a higher fair value measurement. The unobservable input for market convention is not sensitive to input movements. The projected liability cash flows used in the fair value measurement of our Level 3 embedded derivative are based on expected claim payments. If claim payments increase, the projected liability cash flows will increase, resulting in a decrease in the fair value of the embedded derivative. Decreases in projected liability cash flows will result in an increase in the fair value of the embedded derivative.

Fair Value Measurements for Financial Instruments Not Carried at Fair Value

The methods and assumptions used to estimate fair values of financial instruments not carried at fair value are discussed as follows:

Mortgage Loans: Fair values are estimated using discounted cash flow analyses and interest rates currently being offered for similar loans to borrowers with similar credit ratings and maturities. Loans with similar characteristics are aggregated for purposes of the calculations.

Policy Loans: Fair values for policy loans, net of reinsurance ceded, are estimated using discounted cash flow analyses and interest rates currently being offered to policyholders with similar policies. Carrying amounts for ceded policy loans, which equal $3,348.0 million and $3,449.3 million as of June 30, 2019 and December 31, 2018, respectively, approximate fair value and are reported on a gross basis in our consolidated balance sheets. A change in interest rates for ceded policy loans will not impact our financial position because the benefits and risks are fully ceded to reinsuring counterparties.

Miscellaneous Long-term Investments: Carrying amounts for tax credit partnerships equal the unamortized balance of our contractual commitments and approximate fair value. Our shares of FHLB common stock are carried at cost, which approximates fair value.

Long-term Debt: Fair values for long-term debt are obtained from independent pricing services or discounted cash flow analyses based on current incremental borrowing rates for similar types of borrowing arrangements.

FHLB Funding Agreements: Funding agreements with the FHLB represent cash advances used for the purpose of investing in fixed maturity securities. Carrying amounts approximate fair value.

Unfunded Commitments to Investment Partnerships: Unfunded equity commitments represent amounts that we have committed to fund certain investment partnerships. These commitments are legally binding, subject to the partnerships meeting specified conditions. Carrying amounts of these financial instruments approximate fair value.

Note 3 - Fair Values of Financial Instruments - Continued

The carrying values of financial instruments such as short-term investments, cash and bank deposits, accounts and premiums receivable, accrued investment income, securities lending agreements, and short-term debt approximate fair value due to the short-term nature of the instruments. As such, these financial instruments are not included in the above chart.

Fair values for insurance contracts other than investment contracts are not required to be disclosed. However, the fair values of liabilities under all insurance contracts are taken into consideration in our overall management of interest rate risk, which seeks to minimize exposure to changing interest rates through the matching of investment maturities with amounts due under insurance contracts.

The following chart depicts an analysis of our fixed maturity security portfolio between investment-grade and below-investment-grade categories as of June 30, 2019:

					Gross Unrealized Loss
	Fair Value		Gross Unrealized Gain		Amount		Percent of Total Gross Unrealized Loss
	(in millions of dollars)
Investment-Grade	$	43,232.8	$	5,664.6	$	58.5	39.4	%
Below-Investment-Grade	3,207.4		119.2		89.9		60.6
Total Fixed Maturity Securities	$	46,440.2	$	5,783.8	$	148.4	100.0	%

The unrealized losses on investment-grade fixed maturity securities principally relate to changes in interest rates or changes in market or sector credit spreads which occurred subsequent to the acquisition of the securities. Below-investment-grade fixed maturity securities are generally more likely to develop credit concerns than investment-grade securities. At June 30, 2019, the unrealized losses in our below-investment-grade fixed maturity securities were generally due to credit spreads in certain industries or sectors and, to a lesser extent, credit concerns related to specific securities. For each specific security in an unrealized loss position, we believe that there are positive factors which mitigate credit concerns and that the securities for which we have not recorded an other-than-temporary impairment will recover in value.

As of June 30, 2019, we held 105 individual investment-grade fixed maturity securities and 51 individual below-investment-grade fixed maturity securities that were in an unrealized loss position, of which 59 investment-grade fixed maturity securities and 41 below-investment-grade fixed maturity securities had been in an unrealized loss position continuously for over one year.

In determining when a decline in fair value below amortized cost of a fixed maturity security is other than temporary, we evaluate the following factors:

• Whether we expect to recover the entire amortized cost basis of the security

• Whether we intend to sell the security or will be required to sell the security before the recovery of its amortized cost basis

• Whether the security is current as to principal and interest payments

• The significance of the decline in value

• The time period during which there has been a significant decline in value

• Current and future business prospects and trends of earnings

• The valuation of the security's underlying collateral

• Relevant industry conditions and trends relative to their historical cycles

• Market conditions

• Rating agency and governmental actions

• Bid and offering prices and the level of trading activity

• Adverse changes in estimated cash flows for securitized investments

• Changes in fair value subsequent to the balance sheet date

• Any other key measures for the related security

While determining other-than-temporary impairments is a judgmental area, we utilize a formal, well-defined, and disciplined process to monitor and evaluate our fixed income investment portfolio, supported by issuer specific research and documentation as of the end of each period. The process results in a thorough evaluation of problem investments and the recording of losses on a timely basis for investments determined to have an other-than-temporary impairment.

We held no fixed maturity securities as of June 30, 2019 or December 31, 2018 for which a portion of an other-than-temporary impairment was recognized in accumulated other comprehensive income.

At June 30, 2019, we had commitments of $103.5 million to fund private placement fixed maturity securities, the amount of which may or may not be funded.

Variable Interest Entities

We invest in variable interests issued by variable interest entities. These investments include tax credit partnerships, private equity partnerships, and special purpose entities. For those variable interests that are not consolidated in our financial statements, we are not the primary beneficiary because we have neither the power to direct the activities that are most significant to economic performance nor the responsibility to absorb a majority of the expected losses. The determination of whether we are the primary beneficiary is performed at the time of our initial investment and at the date of each subsequent reporting period.

As of June 30, 2019, the carrying amount of our variable interest entity investments that are not consolidated in our financial statements was $614.9 million, comprised of $74.6 million of tax credit partnerships and $540.3 million of private equity partnerships. At December 31, 2018, the carrying amount of our variable interest entity investments that are not consolidated in our financial statements was $575.3 million, comprised of $91.5 million of tax credit partnerships and $483.8 million of private equity partnerships. These variable interest entity investments are reported as other long-term investments in our consolidated balance sheets.

The Company invests in tax credit partnerships primarily for the receipt of income tax credits and tax benefits derived from passive losses on the investments. Amounts recognized in the consolidated statements of income are as follows:

	Three Months Ended June 30						Six Months Ended June 30
	2019			2018			2019			2018
	(in millions of dollars)
Income Tax Credits	$	9.4		$	10.3		$	18.8		$	20.7
Amortization, net of tax	(6.1		)	(7.0		)	(12.9		)	(14.0		)
Income Tax Benefit	$	3.3		$	3.3		$	5.9		$	6.7

Contractually, we are a limited partner in these tax credit partnerships, and our maximum exposure to loss is limited to the carrying value of our investment, which includes $2.3 million of unfunded unconditional commitments at June 30, 2019. See Note 3 for commitments to fund private equity partnerships.

We are the sole beneficiary of a special purpose entity which is consolidated in our financial statements.  This entity is a securitized asset trust containing a highly rated bond for principal protection which we contributed into the trust at the time it was established.  There are no restrictions on the asset held in this trust, and the trust is free to dispose of the asset at any time.  The fair values of the bond were $159.0 million and $156.7 million as of June 30, 2019 and December 31, 2018, respectively.  The bond is reported as a component of fixed maturity securities in our consolidated balance sheets.

Mortgage Loans

Our mortgage loan portfolio is well diversified by both geographic region and property type to reduce risk of concentration. All of our mortgage loans are collateralized by commercial real estate. When issuing a new loan, our general policy is not to exceed a loan-to-value ratio, or the ratio of the loan balance to the estimated fair value of the underlying collateral, of 75 percent. We update the loan-to-value ratios at least every three years for each loan, and properties undergo a general inspection at least every two years. Our general policy for newly issued loans is to have a debt service coverage ratio greater than 1.25 times on a normalized 25 year amortization period. We update our debt service coverage ratios annually. Mortgage loans by property type and geographic region are presented below.

We evaluate each of our mortgage loans individually for impairment and assign an internal credit quality rating based on a comprehensive rating system used to evaluate the credit risk of the loan. The factors we use to derive our internal credit ratings may include the following:

• Loan-to-value ratio

• Debt service coverage ratio based on current operating income

• Property location, including regional economics, trends and demographics

• Age, condition, and construction quality of property

• Current and historical occupancy of property

• Lease terms relative to market

• Tenant size and financial strength

• Borrower's financial strength

• Borrower's equity in transaction

• Additional collateral, if any

Although all available and applicable factors are considered in our analysis, loan-to-value and debt service coverage ratios are the most critical factors in determining whether we will initially issue the loan and also in assigning values and determining impairment. We assign an overall rating to each loan using an internal rating scale of Aa (highest quality) to B (lowest quality). We review and adjust, as needed, our internal credit quality ratings on an annual basis. This review process is performed more frequently for mortgage loans deemed to have a higher risk of delinquency.

Mortgage loans, sorted by the applicable credit quality indicators, are as follows:

	June 30, 2019		December 31, 2018

There were no troubled debt restructurings during the three and six months ended June 30, 2019. We had one mortgage loan which was modified in a troubled debt restructuring during the second quarter of 2018. The loan had a principal balance of $3.6 million prior to the restructuring, wherein the terms of the loan were modified to reduce monthly payments to interest-only at the current note rate and to permit a discounted payoff by September 2018. We recorded an allowance for credit losses on mortgage loans for this restructuring and recognized an impairment loss of $0.2 million in the second quarter of 2018.

At June 30, 2019, we held no mortgage loans that were greater than 90 days past due regarding principal and/or interest payments. At December 31, 2018, we held one mortgage loan that was greater than 90 days past due regarding principal and/or interest payments which was settled during the first quarter of 2019 resulting in an additional loss of $0.1 million.

Our average investment in impaired mortgage loans was zero and $1.1 million for the three and six months ended June 30, 2019, respectively. Our average investment in impaired mortgage loans was $1.1 million for the three and six months ended June 30, 2018. We did not recognize any interest income on mortgage loans subsequent to impairment during the three and six months ended June 30, 2019 or 2018.

There have been no changes to our accounting policies or methodology from the prior period regarding estimating the allowance for credit losses on our mortgage loans. The activity in the allowance for credit losses is as follows:

Transfers of Financial Assets

To manage our cash position more efficiently, we may enter into repurchase agreements with unaffiliated financial institutions. We generally use repurchase agreements as a means to finance the purchase of invested assets or for short-term general business purposes until projected cash flows become available from our operations or existing investments. Our repurchase agreements are typically outstanding for less than 30 days. We post collateral through our repurchase agreement transactions whereby the counterparty commits to purchase securities with the agreement to resell them to us at a later, specified date. The fair value of collateral posted is generally 102 percent of the cash received.

Our investment policy also permits us to lend fixed maturity securities to unaffiliated financial institutions in short-term securities lending agreements. These agreements increase our investment income with minimal risk. Our securities lending policy requires that a minimum of 102 percent of the fair value of the securities loaned be maintained as collateral. We may receive cash and/or securities as collateral under these agreements. Cash received as collateral is typically reinvested in short-term investments. If securities are received as collateral, we are not permitted to sell or re-post them.

As of June 30, 2019, the carrying amount of fixed maturity securities loaned to third parties under our securities lending program was $266.7 million, for which we received collateral in the form of cash and securities of $5.8 million and $274.5 million, respectively. As of December 31, 2018, the carrying amount of fixed maturity securities loaned to third parties under our securities lending program was $164.1 million, for which we received collateral in the form of cash and securities of $0.1 million and $171.4 million, respectively. We had no outstanding repurchase agreements at June 30, 2019 or December 31, 2018.

The remaining contractual maturities of our securities lending agreements disaggregated by class of collateral pledged are as follows:

Certain of our U.S. insurance subsidiaries are members of regional FHLBs. Membership, which requires that we purchase a minimum amount of FHLB common stock on which we receive dividends, provides access to low-cost funding. Advances received from the FHLB are used for the purchase of fixed maturity securities. Additional common stock purchases may be required, based on the amount of funds we borrow from the FHLBs.

Offsetting of Financial Instruments

We enter into master netting agreements with each of our derivatives counterparties. These agreements provide for conditional rights of set-off upon the occurrence of an early termination event. An early termination event is considered a default, and it allows the non-defaulting party to offset its contracts in a loss position against any gain positions or payments due to the defaulting party. Under our agreements, default type events are defined as failure to pay or deliver as contractually agreed, misrepresentation, bankruptcy, or merger without assumption. See Note 5 for further discussion of collateral related to our derivative contracts.

We have securities lending agreements with unaffiliated financial institutions that post collateral to us in return for the use of our fixed maturity securities. A right of set-off exists that allows us to keep and apply collateral received in the event of default by the counterparty. Default within a securities lending agreement would typically occur if the counterparty failed to return the securities borrowed from us as contractually agreed. In addition, if we default by not returning collateral received, the counterparty has a right of set-off against our securities or any other amounts due to us.

Shown below are our financial instruments that either meet the accounting requirements that allow them to be offset in our balance sheets or that are subject to an enforceable master netting arrangement or similar agreement. Our accounting policy is to not offset these financial instruments in our balance sheets. Net amounts disclosed below have been reduced by the amount of collateral pledged to or received from our counterparties.

Note 5 - Derivative Financial Instruments

Purpose of Derivatives

We are exposed to certain risks relating to our ongoing business operations. The primary risks managed by using derivative instruments are interest rate risk, risk related to matching duration for our assets and liabilities, foreign currency risk, and credit risk. Historically, we have utilized current and forward interest rate swaps, current and forward currency swaps, forward benchmark interest rate locks, currency forward contracts, forward contracts on specific fixed income securities, and credit default swaps. Transactions hedging interest rate risk are primarily associated with our individual and group long-term care and individual and group disability products. All other product portfolios are periodically reviewed to determine if hedging strategies would be appropriate for risk management purposes. We do not use derivative financial instruments for speculative purposes.

Derivatives designated as cash flow hedges and used to reduce our exposure to interest rate and duration risk are as follows:

• Interest rate swaps are used to hedge interest rate risks and to improve the matching of assets and liabilities. An interest rate swap is an agreement in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and variable rate interest amounts. We use interest rate swaps to hedge the anticipated purchase of fixed maturity securities thereby protecting us from the potential adverse impact of declining interest rates on the associated policy reserves. We also use interest rate swaps to hedge the potential adverse impact of rising interest rates in anticipation of issuing fixed rate long-term debt.

• Forward benchmark interest rate locks are used to minimize interest rate risk associated with the anticipated purchase or disposal of fixed maturity securities. A forward benchmark interest rate lock is a derivative contract without an initial investment where we and the counterparty agree to purchase or sell a specific benchmark interest rate bond at a future date at a pre-determined price.

Note 5 - Derivative Financial Instruments - Continued

Derivatives designated as fair value hedges and used to reduce our exposure to interest rate and duration risk are as follows:

• Interest rate swaps are used to effectively convert certain of our fixed rate securities into floating rate securities which are used to fund our floating rate long-term debt. Under these swap agreements, we receive a variable rate of interest and pay a fixed rate of interest. Additionally, we use interest rate swaps to effectively convert certain fixed rate, long-term debt into floating rate long-term debt. Under these swap agreements, we receive a fixed rate of interest and pay a variable rate of interest.

Derivatives designated as either cash flow or fair value hedges and used to reduce our exposure to foreign currency risk are as follows:

• Foreign currency interest rate swaps are used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification. Under these swap agreements, we agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment.

Derivatives not designated as hedging instruments and used to reduce our exposure to foreign currency risk, credit losses on securities owned, and interest rate risk are as follows:

• Foreign currency interest rate swaps previously designated as hedges were used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification. These derivatives were effective hedges prior to novation to a new counterparty. In conjunction with the novation, these derivatives were de-designated as hedges. We agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment. We hold offsetting swaps wherein we agree to pay fixed rate principal and interest payments in the functional currency of the operating segment in exchange for fixed rate foreign currency-denominated payments.

• Credit default swaps are used as economic hedges against credit risk but do not qualify for hedge accounting. A credit default swap is an agreement in which we agree with another party to pay, at specified intervals, a fixed-rate fee in exchange for insurance against a credit event on a specific investment. If a defined credit event occurs, our counterparty may either pay us a net cash settlement or we may surrender the specific investment to them in exchange for cash equal to the full notional amount of the swap. Credit events typically include events such as bankruptcy, failure to pay, or certain types of debt restructuring.

• Interest rate swap was used to effectively convert certain of our floating rate, long-term debt into fixed rate long-term debt. Under this swap agreement, we received a variable rate of interest and paid a fixed rate of interest.

• Foreign currency forward contracts are used to minimize foreign currency risk. A foreign currency forward is a derivative without an initial investment where we and the counterparty agree to exchange a specific amount of currencies, at a specific exchange rate, on a specific date. We use these forward contracts to hedge the currency risk arising from foreign-currency denominated securities.

Derivative Risks

The basic types of risks associated with derivatives are market risk (that the value of the derivative will be adversely impacted by changes in the market, primarily the change in interest and exchange rates) and credit risk (that the counterparty will not perform according to the terms of the contract). The market risk of the derivatives should generally offset the market risk associated with the hedged financial instrument or liability. To help limit the credit exposure of the derivatives, we enter into master netting agreements with our counterparties whereby contracts in a gain position can be offset against contracts in a loss position. We also typically enter into bilateral, cross-collateralization agreements with our counterparties to help limit the credit exposure of the derivatives. These agreements require the counterparty in a loss position to submit acceptable collateral with the other counterparty in the event the net loss position meets or exceeds an agreed upon amount. Credit exposure on derivatives is limited to the value of those contracts in a net gain position, including accrued interest receivable less collateral held. At June 30, 2019, we had no credit exposure on derivatives. As of December 31, 2018, we had $0.9 million credit exposure on derivatives. The table below summarizes the nature and amount of collateral received from and posted to our derivative counterparties.

	June 30, 2019		December 31, 2018
	(in millions of dollars)
Carrying Value of Collateral Received from Counterparties
Cash	$	22.3	$	24.0
Carrying Value of Collateral Posted to Counterparties
Fixed Maturity Securities	$	30.4	$	33.4

See Note 4 for further discussion of our master netting agreements.

The majority of our derivative instruments contain provisions that require us to maintain specified issuer credit ratings and financial strength ratings. Should our ratings fall below these specified levels, we would be in violation of the provisions, and our derivatives counterparties could terminate our contracts and request immediate payment. The aggregate fair value of all derivative instruments with credit risk-related contingent features that were in a liability position was $36.2 million and $38.0 million at June 30, 2019 and December 31, 2018, respectively.

Cash Flow Hedges

As of June 30, 2019 and December 31, 2018, we had $232.9 million and $286.4 million, respectively, notional amount of receive fixed, pay fixed, open current and forward foreign currency interest rate swaps to hedge fixed income foreign currency-denominated securities.

As of June 30, 2019, we expect to amortize approximately $71.7 million of net deferred gains on derivative instruments during the next twelve months. This amount will be reclassified from accumulated other comprehensive income into earnings and reported on the same income statement line item as the hedged item. The income statement line items that will be affected by this amortization are net investment income and interest and debt expense. Additional amounts that may be reclassified from accumulated other comprehensive income into earnings to offset the earnings impact of foreign currency translation of hedged items are not estimable.

As of June 30, 2019, we are hedging the variability of future cash flows associated with forecasted transactions through the year 2045.

As of June 30, 2019 and December 31, 2018, we had $250.0 million notional amount of receive fixed, pay variable interest rate swaps to hedge the changes in the fair value of certain fixed rate long-term debt. These swaps effectively convert the associated fixed rate long-term debt into floating rate debt and provide for a better matching of interest rates with our short-term investments, which have frequent interest rate resets similar to a floating rate security.

The following table summarizes the carrying amount of hedged assets and liabilities and the related cumulative basis adjustments related to our fair value hedges.

	Carrying Amount of Hedged Assets (Liabilities)						Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets (Liabilities)
	June 30, 2019			December 31, 2018			June 30, 2019			December 31, 2018
	(in millions of dollars)
Fixed maturity securities:
Receive fixed functional currency interest, pay fixed foreign currency interest	$	120.7		$	56.2		$	(1.9	)	$	(2.7	)
Long-term Debt	(248.1		)	(244.4		)	1.5			5.1

For the three and six months ended June 30, 2019, $1.6 million and $1.5 million, respectively, of the derivative instruments' gain was excluded from the assessment of hedge effectiveness. For the three and six months ended June 30, 2018, $1.0 million of the derivative instruments' gain was excluded from the assessment of hedge effectiveness. There were no instances wherein we discontinued fair value hedge accounting due to a hedged firm commitment no longer qualifying as a fair value hedge.

Derivatives not Designated as Hedging Instruments

As of June 30, 2019 and December 31, 2018, we held $148.2 million and $173.7 million, respectively, notional amount of receive fixed, pay fixed, foreign currency interest rate swaps. These derivatives are not designated as hedges, and as such, changes in fair value related to these derivatives are reported in earnings as a component of net realized investment gain or loss.

As of June 30, 2019 and December 31, 2018, we held $10.9 million and $11.0 million, respectively, notional amount of single name credit default swaps. We entered into these swaps in order to mitigate the credit risk associated with specific securities owned.

We have an embedded derivative in a modified coinsurance arrangement for which we include in our realized investment gains and losses a calculation intended to estimate the value of the option of our reinsurance counterparty to cancel the reinsurance contract with us. However, neither party can unilaterally terminate the reinsurance agreement except in extreme circumstances resulting from regulatory supervision, delinquency proceedings, or other direct regulatory action. Cash settlements or collateral related to this embedded derivative are not required at any time during the reinsurance contract or at termination of the reinsurance contract. There are no credit-related counterparty triggers, and any accumulated embedded derivative gain or loss reduces to zero over time as the reinsured business winds down.

Plus Reinsurance Recoverable	2,247.7			2,188.4
Balance at June 30	$	23,090.6		$	23,045.2

The majority of the net balances are related to disability claims with long-tail payouts on which interest earned on assets backing liabilities is an integral part of pricing and reserving. Interest accrued on prior year reserves has been calculated on the opening reserve balance less one-half of the period's claim payments relative to prior years at our average reserve discount rate for the respective periods.

"Incurred Related to Prior Years - All Other Incurred" shown in the preceding chart is primarily impacted by the level of claim resolutions in the period relative to the long-term expectations reflected in the reserves. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the life of the block of business and will vary from actual experience in any one period, both favorably and unfavorably.

Accident and Health Active Life Reserves	12,008.3		10,895.6
Adjustment Related to Unrealized Investment Gains and Losses	5,455.7		3,367.1
Liability for Unpaid Claims and Claim Adjustment Expenses	$	23,090.6	$	23,045.2

The adjustment related to unrealized investment gains and losses reflects the changes that would be necessary to policyholder liabilities if the unrealized investment gains and losses related to the corresponding available-for-sale securities had been realized. Changes in this adjustment are reported as a component of other comprehensive income or loss.

We measure and analyze our segment performance on the basis of "adjusted operating revenue" and "adjusted operating income" or "adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of income due to the exclusion of net realized investment gains and losses as specified in the reconciliations below. We believe adjusted operating revenue and adjusted operating income or loss are better performance measures and better indicators of the revenue and profitability and underlying trends in our business. These performance measures are in accordance with GAAP guidance for segment reporting, but they should not be viewed as a substitute for total revenue, income before income tax, or net income. 

Realized investment gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of realized investment gains or losses. Although we may experience realized investment gains or losses which will affect future earnings levels, a long-term focus is necessary to maintain profitability over the life of the business since our underlying business is long-term in nature, and we need to earn the interest rates assumed in calculating our liabilities.

We may at other times exclude certain other items from our discussion of financial ratios and metrics in order to enhance the understanding and comparability of our operational performance and the underlying fundamentals. We exclude these items as we believe them to be infrequent or unusual in nature, but this exclusion is not an indication that similar items may not recur and does not replace net income or net loss as a measure of our overall profitability.

A reconciliation of total revenue to "adjusted operating revenue" and income before income tax to "adjusted operating income" is as follows:

Note 9 - Employee Benefit Plans

Defined Benefit Pension and Other Postretirement Benefit (OPEB) Plans

We sponsor several defined benefit pension and OPEB plans for our employees, including non-qualified pension plans. The U.S. qualified and non-qualified defined benefit pension plans comprise the majority of our total benefit obligation and benefit cost. We maintain a separate defined benefit plan for eligible employees in our U.K. operation. The U.S. defined benefit pension plans were closed to new entrants on December 31, 2013, the OPEB plan was closed to new entrants on December 31, 2012, and the U.K. plan was closed to new entrants on December 31, 2002.

The following table provides the components of the net periodic benefit cost (credit) for the defined benefit pension and OPEB plans.

Note 10 - Stockholders' Equity and Earnings Per Common Share

Earnings Per Common Share

Net income per common share is determined as follows:

	Three Months Ended June 30				Six Months Ended June 30
	2019		2018		2019		2018
	(in millions of dollars, except share data)
Numerator

Weighted Average Common Shares - Basic	211,068.7		220,776.7		212,672.8		221,335.7
Dilution for Assumed Exercises of Stock Options and Nonvested Stock Awards	43.9		286.0		88.3		484.5
Weighted Average Common Shares - Assuming Dilution	211,112.6		221,062.7		212,761.1		221,820.2
Net Income Per Common Share
Basic	$	1.33	$	1.29	$	2.64	$	2.53
Assuming Dilution	$	1.33	$	1.29	$	2.64	$	2.52

We use the treasury stock method to account for the effect of outstanding stock options, nonvested restricted stock units, and nonvested performance share units on the computation of diluted earnings per share. Under this method, these potential common shares will each have a dilutive effect, as individually measured, when the average market price of Unum Group common stock during the period exceeds the exercise price of the stock options and the grant price of the nonvested restricted stock units and the nonvested performance share units. The outstanding stock options have exercise prices ranging from $23.35 to $24.25, the nonvested restricted stock units have grant prices ranging from $33.28 to $55.26, and the nonvested performance share units have grant prices ranging from $37.67 to $49.86.

In computing earnings per share assuming dilution, only potential common shares that are dilutive (those that reduce earnings per share) are included. Potential common shares excluded in the computation of diluted earnings per share because the impact would be antidilutive, based on then current market prices, approximated 1.2 million potential common shares for both the three and six months ended June 30, 2019. There were approximately 0.7 million and 0.4 million potential common shares that were antidilutive for the three and six months ended June 30, 2018, respectively.

Common Stock

During the second quarter of 2019, our board of directors authorized the repurchase of up to $750.0 million of Unum Group's outstanding common stock through November 23, 2020. This authorization replaced the previous authorization of $750.0 million that was scheduled to expire on November 24, 2019. The remaining repurchase amount under the new program was $716.2 million at June 30, 2019.

Preferred Stock

Unum Group has 25.0 million shares of preferred stock authorized with a par value of $0.10 per share. No preferred stock has been issued to date.

Note 11 - Commitments and Contingent Liabilities

Contingent Liabilities

We are a defendant in a number of litigation matters that have arisen in the normal course of business. Further, state insurance regulatory authorities and other federal and state authorities regularly make inquiries and conduct investigations concerning our compliance with applicable insurance and other laws and regulations. Given the complexity and scope of our litigation and regulatory matters, it is not possible to predict the ultimate outcome of all pending investigations or legal proceedings or provide reasonable estimates of potential losses, except if noted in connection with specific matters.

In some of these matters, no specified amount is sought. In others, very large or indeterminate amounts, including punitive and treble damages, are asserted. There is a wide variation of pleading practice permitted in the United States courts with respect to requests for monetary damages, including some courts in which no specified amount is required and others which allow the plaintiff to state only that the amount sought is sufficient to invoke the jurisdiction of that court. Further, some jurisdictions permit plaintiffs to allege damages well in excess of reasonably possible verdicts. Based on our extensive experience and that of others in the industry with respect to litigating or resolving claims through settlement over an extended period of time, we believe that the monetary damages asserted in a lawsuit or claim bear little relation to the merits of the case, or the likely disposition value. Therefore, the specific monetary relief sought is not stated.

Unless indicated otherwise in the descriptions below, reserves have not been established for litigation and contingencies. An estimated loss is accrued when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

Claims Handling Matters

We and our insurance subsidiaries, in the ordinary course of our business, are engaged in claim litigation where disputes arise as a result of a denial or termination of benefits. Most typically these lawsuits are filed on behalf of a single claimant or policyholder, and in some of these individual actions punitive damages are sought, such as claims alleging bad faith in the handling of insurance claims. For our general claim litigation, we maintain reserves based on experience to satisfy judgments and settlements in the normal course. We expect that the ultimate liability, if any, with respect to general claim litigation, after consideration of the reserves maintained, will not be material to our consolidated financial condition. Nevertheless, given the inherent unpredictability of litigation, it is possible that an adverse outcome in certain claim litigation involving punitive damages could, from time to time, have a material adverse effect on our consolidated results of operations in a period, depending on the results of operations for the particular period.

Note 11 - Commitments and Contingent Liabilities - Continued

From time to time class action allegations are pursued where the claimant or policyholder purports to represent a larger number of individuals who are similarly situated. Since each insurance claim is evaluated based on its own merits, there is rarely a single act or series of actions which can properly be addressed by a class action. Nevertheless, we monitor these cases closely and defend ourselves appropriately where these allegations are made.

Miscellaneous Matters

Similar to other insurers, we were the subject of an examination by a third party acting on behalf of a number of state treasurers concerning our compliance with the unclaimed property laws of the participating states. We cooperated fully with this examination and in the fourth quarter of 2017, we started the process to reach a Global Resolution Agreement with the third party regarding settlement of the examination, which we finalized in January of 2018. Under the terms of the agreement, the third party acting on behalf of the signatory states compared insured data to the Social Security Administration's Death Master File to identify deceased insureds and contract holders where a valid claim has not been made. During the fourth quarter of 2017, we established reserves which reflect our estimate of the liability expected to be paid as we execute on the terms of the settlement. We also are cooperating with a Delaware Market Conduct examination involving the same issue, which is currently inactive. The legal and regulatory environment around unclaimed death benefits continues to evolve. It is possible that the current settlement and/or similar investigations by other state jurisdictions may result in payments to beneficiaries, the payment of abandoned funds under state law, and/or administrative penalties, the total of which may be in excess of the reserves established.

In 2009, a Pennsylvania-based insurance company and its affiliates were ordered into rehabilitation, and the Pennsylvania Insurance Commissioner, who was appointed as the Rehabilitator, filed petitions for liquidation with the Commonwealth Court of Pennsylvania. Under Pennsylvania law, payment of covered claims and other related insurance obligations are provided, within prescribed limits, by state guaranty associations. These guaranty associations assess fees to meet these obligations on insurance companies that sell insurance within the state, which are generally based on a company's pro rata portion of average premiums written or received for several years prior to the insolvency. In March 2017, a formal order of liquidation was issued, and as such, we were subject to an assessment by those guaranty associations that are responsible for policyholder claims, and accordingly accrued, in the first quarter of 2017, an estimated loss contingency. We continue to submit payment to satisfy this assessment as requests for payment are received from the guaranty associations.

Securities Class Actions: Three alleged securities class action lawsuits have been filed against Unum Group and individual defendants as follows:

• On June 13, 2018, an alleged securities class action lawsuit entitled Cynthia Pittman v. Unum Group, Richard McKenney, John McGarry, and Daniel Waxenberg was filed in the United States District Court for the Eastern District of Tennessee. The plaintiff seeks to represent purchasers of Unum Group publicly traded securities between January 31, 2018 and May 2, 2018. The plaintiff alleges the Company caused its shares to trade at artificially high levels by failing to disclose information about the rate of long-term care policy terminations and long-term care claim incidence resulting in misleading statements about capital management plans and long-term care reserves. The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder and seeks compensatory damages in an amount to be proven at trial. The Company strongly denies these allegations and will vigorously defend the litigation.

• On July 13, 2018, an alleged securities class action lawsuit entitled Scott Cunningham v. Unum Group, Richard McKenney, John McGarry, and Daniel Waxenberg was filed in the United States District Court for the Eastern District of Tennessee. The allegations, class period, and damages claimed mirror those in the Pittman matter. The Company strongly denies these allegations and will vigorously defend the litigation.

• On July 25, 2018, an alleged securities class action lawsuit entitled City of Taylor Police and Fire Retirement System v. Unum Group, Richard McKenney, John McGarry, Steve Zabel, and Daniel Waxenberg was filed in the United States District Court for the Eastern District of Tennessee. The plaintiff seeks to represent purchasers of Unum Group publicly traded securities between October 27, 2016 and May 1, 2018. The allegations and damages claimed mirror those in the Pittman matter. The Company strongly denies these allegations and will vigorously defend the litigation.

Note 11 - Commitments and Contingent Liabilities - Continued

On November 9, 2018, the court consolidated the Pittman, Cunningham, and City of Taylor Police and Fire Retirement System cases into one matter entitled In re Unum Group Securities Litigation, appointed a lead plaintiff and lead plaintiff’s counsel, and directed the plaintiff to file a consolidated amended complaint. On January 15, 2019, the plaintiff filed a consolidated amended complaint asserting claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder and seeks compensatory damages in an amount to be proven at trial as well as costs, expenses, and attorney’s fees. On March 18, 2019, the Company filed a motion to dismiss the consolidated amended complaint.

These lawsuits are in a very preliminary stage, the outcome is uncertain, and the Company is unable to estimate a range of reasonably possible losses. Reserves have not been established for these matters. Although we believe these claims lack merit, an adverse outcome in one or more of these actions could, depending on the nature, scope, and amount of the ruling, materially adversely affect our consolidated results of operations in a period.

Note 12 - Leases

We lease certain buildings and equipment under various noncancelable operating lease agreements. In addition, we have sub-lease agreements on a limited number of our building lease agreements. The majority of our building leases and sub-leases expire within a five to ten year period and we generally have the option to renew at the end of the lease term for an additional five to ten year period at the fair rental value at the time of renewal. The majority of our equipment leases expire within a one to three year period and we generally have the option to renew at the end of the lease term for an additional one to three year period at the fair rental value at the time of renewal.

We do not have any lease agreements or sub-lease agreements that contain variable lease payments. In addition, we do not have lease agreements or sub-lease agreements that contain residual value guarantees or impose any restrictions or covenants with the lessors.

We determine if an arrangement is a lease at inception through a formal process that evaluates our right to control the use of an identified asset for a period of time in exchange for consideration. We account for the lease and non-lease components of our building leases separately and have elected to use the available practical expedient to account for the lease and non-lease components of our equipment leases as a single component. All of our leases are classified as operating, none of which are classified as short-term leases. For each operating lease, we calculate a lease liability at commencement date based on the present value of lease payments over the lease term and a corresponding right-of-use (ROU) asset, adjusted for lease incentives.

ROU assets represent our right to use an underlying asset for a specified lease term and are included in other assets in our consolidated balance sheet. Lease liabilities represent the present value of lease payments that we are obligated to pay arising from a lease and are included in other liabilities in our consolidated balance sheet. We consider the likelihood of renewal in determining the lease terms for the calculation of the ROU asset and lease liability. As most of our leases do not provide an implicit rate of interest, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate of interest when readily determinable.

Operating lease cost is calculated on a straight-line basis over the lease term and is included in other expenses in our consolidated statement of income. We amortize the ROU asset over the lease term on a pattern determined by the difference between the straight-line lease liability expense and the accretion of the imputed interest calculated on the lease liability.

Note 13 - Debt

During the six months ended June 30, 2019, we made principal payments of $30.0 million on our senior secured non-recourse notes issued by Northwind Holdings, LLC.

In June 2019, we issued $400.0 million of 4.00% senior notes due 2029. The notes are callable at or above par and rank equally in the right of payment with all of our other unsecured and unsubordinated debt.

In April 2019, we amended the terms of our existing five-year unsecured revolving credit facility, increasing it from $400.0 million to $500.0 million. The credit facility, which was previously set to expire in 2021, was extended through April 2024. Under the terms of the amended agreement, we may request that the credit facility be increased up to $700.0 million, up from the previous amount of $600.0 million. We also may request, on up to two occasions, that the lenders' commitment termination dates be extended by one year. The credit facility provides for the issuance of letters of credit subject to certain terms and limitations. At June 30, 2019, letters of credit totaling $2.0 million had been issued from the credit facility, but there were no borrowed amounts outstanding.

Also in April 2019, we separately entered into a three-year, $100.0 million unsecured revolving credit facility with a different syndicate of lenders, which is set to expire in April 2022. Under the terms of the agreement, we may request that the credit facility be increased up to $140.0 million. We also may request that the lenders' commitment termination dates be extended by

one year. The credit facility provides for the issuance of letters of credit subject to certain terms and limitations. At June 30, 2019, there have been no letters of credit issued from the credit facility and there were no borrowed amounts outstanding.

Borrowings under the credit facilities are for general corporate uses and are subject to financial covenants, negative covenants, and events of default that are customary. The two primary financial covenants include limitations based on our leverage ratio and consolidated net worth. We are also subject to covenants that limit subsidiary indebtedness. The credit facilities provide for borrowings at an interest rate based either on the prime rate or LIBOR.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Executive Summary

Unum Group, a Delaware general business corporation, and its insurance and non-insurance subsidiaries, which collectively with Unum Group we refer to as the Company, operate in the United States, the United Kingdom, Poland and, to a limited extent, in certain other countries. The principal operating subsidiaries in the United States are Unum Life Insurance Company of America, Provident Life and Accident Insurance Company, The Paul Revere Life Insurance Company, Colonial Life & Accident Insurance Company, Starmount Life Insurance Company, in the United Kingdom, Unum Limited, and in Poland, Unum Zycie TUiR S.A. (Unum Poland). We are a leading provider of financial protection benefits in the United States and the United Kingdom. Our products include disability, life, accident, critical illness, dental and vision, and other related services. We market our products primarily through the workplace.

We have three principal operating business segments: Unum US, Unum International, and Colonial Life. Our other segments are the Closed Block and Corporate segments. These segments are discussed more fully under "Segment Results" included herein in this Item 2.

The benefits we provide help protect people from the financial hardship of illness, injury, or loss of life by providing support when it is needed most. As one of the leading providers of employee benefits in the U.S. and the U.K., we offer a broad portfolio of products and services through the workplace.

Specifically, we offer group, individual, and voluntary benefits, either as stand-alone products or combined with other coverages, that help employers of all sizes attract and retain a stronger workforce while protecting the incomes and livelihood of their employees. We believe employer-sponsored benefits represent the single most effective way to provide workers with access to the information and options they need to protect their financial stability. Working people and their families, particularly those at lower and middle incomes, are perhaps the most vulnerable in today's economy yet are often overlooked by many providers of financial services and products. For many of these people, employer-sponsored benefits are the primary defense against the potentially catastrophic fallout of death, illness, or injury.

We have established a corporate culture consistent with the social values our products provide. We are committed not only to meeting the needs of our customers who depend on us, but also to operating with integrity and being accountable for our actions. Our sound and consistent business practices, strong internal compliance program, and comprehensive risk management strategy enable us to operate efficiently as well as to identify and address potential areas of risk in our business. We have also applied these same values to our social responsibility efforts. Because we see important links between the obligations we have to all of our stakeholders, we place a strong emphasis on contributing to positive change in our communities.

This discussion and analysis should be read in conjunction with the consolidated financial statements and notes thereto in Part I, Item 1 contained in this Form 10-Q and with the "Cautionary Statement Regarding Forward-Looking Statements" included below the Table of Contents, as well as the discussion, analysis, and consolidated financial statements and notes thereto in Part I, Items 1 and 1A, and Part II, Items 6, 7, 7A, and 8 of our annual report on Form 10-K for the year ended December 31, 2018.

Operating Performance and Capital Management

For the second quarter of 2019, we reported net income of $281.2 million, or $1.33 per common share, compared to net income of $285.5 million, or $1.29 per diluted common share, in the same period of 2018. For the first six months of 2019, net income was $562.1 million, or $2.64 per diluted common share, compared to net income of $559.0 million, or $2.52 per diluted common share in the same period of 2018. Net income includes net realized investment gains and losses. Excluding net realized investment gains and losses, after-tax adjusted operating income in the second quarter of 2019 was $286.9 million, or $1.36 per diluted common share, compared to $287.6 million, or $1.30 per diluted common share, in the same period of 2018. After-tax adjusted operating income was $567.2 million, or $2.67 per diluted common share, in the first six months of 2019, compared to $562.7 million, or $2.54 per diluted common share, in the first six months of 2018. See "Reconciliation of Non-GAAP and Other Financial Measures" contained in this Item 2 for a reconciliation of these items.

Our Unum US segment reported an increase in adjusted operating income of 1.3 percent and 2.3 percent in the second quarter and first six months of 2019, respectively, compared to the same periods of 2018, with growth in premium income, partially offset by lower net investment income. Also impacting the results for the six months ended 2019 was higher amortization of deferred acquisition costs. The benefit ratio for our Unum US segment was 67.6 percent and 66.5 percent in the second quarter and first six months of 2019, respectively, compared to 67.0 percent and 66.9 percent in the second quarter and first six months of 2018. Unum US sales increased 12.1 percent and 5.9 percent in the second quarter and first six months of 2019, respectively, compared to the same periods of 2018. Relative to the prior year, persistency in our group product lines was favorable while persistency in our supplemental and voluntary product lines was less favorable.

Our Unum International segment reported an increase in adjusted operating income, as measured in U.S. dollars, of 11.2 percent and 4.2 percent in the second quarter and first six months of 2019, respectively, compared to the same periods of 2018. As measured in local currency, our Unum UK line of business reported an increase in adjusted operating income of 11.3 percent and 6.0 percent in the second quarter and first six months of 2019, respectively, compared to the same periods of 2018, due to premium growth and higher net investment income, partially offset by unfavorable benefits experience. The benefit ratio for Unum UK was 85.6 percent and 78.1 percent in the second quarter and first six months of 2019, respectively, compared to 76.7 percent and 74.3 percent in the same periods of 2018. Unum UK sales in local currency increased 0.5 percent and 7.6 percent in the second quarter and first six months of 2019 compared to the same periods of 2018. Persistency was favorable relative to the prior year.

Our Colonial Life segment reported a decrease in adjusted operating income of 0.2 percent in the second quarter of 2019 compared to the same period of 2018 but reported an increase of 2.4 percent in the first six months of 2019 compared to the same period of 2018. Impacting the results in each period was premium growth, lower net investment income, and higher amortization of deferred acquisition costs. The benefit ratio for Colonial Life was 51.4 percent and 51.2 percent in the second quarter and first six months of 2019, respectively, compared to 51.0 percent and 51.3 percent in the same periods of 2018. Colonial Life sales decreased 4.2 percent and 0.2 percent in the second quarter and first six months of 2019, respectively, compared to the same periods of 2018. Persistency was lower relative to the prior year.

Our Closed Block segment reported an increase in adjusted operating income of 13.9 percent and 10.6 percent in the second quarter and first six months of 2019, respectively, compared to the same periods of 2018, due primarily to an increase in net investment income, partially offset by lower premium income. Benefits experience in our individual disability line of business remains consistent with our expectations, with favorable experience in the second quarter of 2019 compared to the same prior year period and slightly unfavorable experience during the first six months of 2019 compared to the same prior year period. Benefits experience in our long-term care line of business, during the second quarter and first six months of 2019 was not comparable to the same prior year periods due to the update in our assumptions during the third quarter of 2018, but was consistent with our expectations.

Although our profit margins continue to be pressured by the impact of the low interest rate environment on our net investment income yields, our invested asset quality remains strong. The net unrealized gain on our fixed maturity securities was $5.6 billion at June 30, 2019 compared to $2.7 billion at December 31, 2018, with the increase due to a decrease in U.S. Treasury rates and credit spreads during the first six months of 2019. The earned book yield on our investment portfolio was 5.04 percent for the first six months of 2019 compared to a yield of 5.15 percent for full year 2018.

We believe our capital and financial positions are strong. At June 30, 2019, the risk-based capital (RBC) ratio for our traditional U.S. insurance subsidiaries, calculated on a weighted average basis using the NAIC Company Action Level formula, was approximately 365 percent, which is in line with our expectations. During the first six months of 2019, we repurchased 5.6 million shares of Unum Group common stock under our share repurchase program, at a cost of approximately $200 million. Our

65

weighted average common shares outstanding, assuming dilution, equaled 211.1 million and 221.1 million for the second quarter of 2019 and 2018, respectively, and 212.8 million and 221.8 million for first six months of 2019 and 2018, respectively, reflecting our capital management strategy of returning capital to shareholders through repurchases of our common stock. As of June 30, 2019, Unum Group and our intermediate holding companies held fixed maturity securities, short-term investments, and cash of $977 million.

2018 Long-term Care Reserve Increase

Policy reserves for our long-term care block of business are determined using the gross premium valuation method and, prior to the third quarter of 2018, were valued based on assumptions established as of December 31, 2014, the date of our last assumption update under loss recognition. Gross premium valuation assumptions do not change after the date of loss recognition unless reserves are again determined to be deficient. We undertake a review of policy reserve adequacy annually during the fourth quarter of each year, or more frequently if appropriate, using best estimate assumptions as of the date of the review.

During the third quarter of 2018, we completed our annual review of policy reserve adequacy, which incorporated our most recent experience and included a review of all assumptions. The review utilized internal and external data and outside consulting firms for quality assurance and industry benchmarking. Based on our analysis, during the third quarter of 2018, we updated our reserve assumptions and determined that our policy and claim reserves should be increased by $750.8 million, or $593.1 million after-tax, to reflect our current estimate of future benefit obligations. This increase was primarily driven by the update to our liability and interest rate assumptions, particularly claims incidence and claim termination rates, which resulted in an increase to reserves of approximately $2.2 billion. Partially offsetting the increase was the update to our assumptions for premium rate increases which decreased reserves approximately $1.4 billion, resulting in the net increase to reserves of $750.8 million.

U.K. Referendum

During 2016, the U.K. held a referendum and voted to leave the EU. The U.K. subsequently invoked Article 50 of the Treaty on European Union (EU) and the deadline to leave the EU is currently set for October 31, 2019, which was recently extended from the original date of March 29, 2019. We may see some continued dampening of growth in the U.K. as well as earnings volatility due to the current disruption and uncertainty in the U.K. economy. We may also experience volatility in the fair values of our investments in U.K. and EU-based issuers, but we do not expect a material increase in other-than-temporary impairments or defaults, nor do we believe this volatility will impact our ability to hold these investments. The magnitude and longevity of potential negative economic impacts on our growth will depend on whether an agreement is reached between the U.K. and EU as a result of exit negotiations and, if reached, the nature of the agreement and the resulting response of the U.K. marketplace. There are currently no indications that capital requirements for our U.K. operations will change, but economic conditions may cause volatility in our solvency ratios. Our reported consolidated financial results may continue to be impacted by fluctuations in the British pound sterling to dollar exchange rate. Further discussion is contained herein in "Unum International Segment" in this Item 2.

Consolidated Company Outlook

We believe our disciplined approach to providing financial protection products at the workplace puts us in a position of strength as we seek to capitalize on the growing and largely unfilled need for our products and services. We believe the need for our products and services remains strong, and we intend to continue protecting our solid margins and returns through our pricing and risk actions. Our strategy is underpinned by our core values and is centered on market growth through the expansion of our product portfolio, distribution system, and geographic footprint, and enhancing the customer experience through efficiency, simplification, and investment in digital capabilities. 

We expect to see continued solid premium growth trends in our core businesses, with stable persistency and a disciplined approach to sales growth. We expect to have generally stable benefits experience due to our focus on disciplined pricing, risk selection, and management of renewals. We will maintain our commitment to expense discipline and improving our operational efficiencies.

The low interest rate environment continues to place pressure on our profit margins. Our reported consolidated financial results may also continue to be unfavorably impacted by political and economic uncertainty in the U.K., specifically lower interest rates, wage inflation and employer spending, and claims volatility. We expect our effective tax rate for 2019 to be approximately 20 percent. The reduction in the corporate tax rate resulting from tax reform has improved the statutory earnings and cash generation of our insurance subsidiaries and our capital position remains strong.

66

We continue to analyze and employ strategies that we believe will help us navigate the current environment and allow us to maintain solid operating margins and significant financial flexibility to support the needs of our businesses, while also continuing to return capital to our shareholders and exploring merger and acquisition opportunities to enhance our business lines. We have substantial leverage to rising interest rates and an improving economy which generates payroll growth and wage inflation. We believe that consistent operating results, combined with the implementation of strategic initiatives and the effective deployment of capital, will allow us to meet our long-term financial objectives.

Further discussion is contained in this Item 2 and in the "Notes to Consolidated Financial Statements" contained herein in Item 1.

Reconciliation of Non-GAAP and Other Financial Measures

We analyze our performance using non-GAAP financial measures. A non-GAAP financial measure is a numerical measure of a company's performance, financial position, or cash flows that excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP financial measure of "after-tax adjusted operating income" differs from net income as presented in our consolidated operating results and income statements prepared in accordance with GAAP due to the exclusion of net realized investment gains and losses as specified in the reconciliations below. We believe after-tax adjusted operating income is a better performance measure and better indicator of the profitability and underlying trends in our business.

Realized investment gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of realized investment gains or losses. Although we may experience realized investment gains or losses which will affect future earnings levels, a long-term focus is necessary to maintain profitability over the life of the business since our underlying business is long-term in nature, and we need to earn the interest rates assumed in calculating our liabilities.

We may at other times exclude certain other items from our discussion of financial ratios and metrics in order to enhance the understanding and comparability of our operational performance and the underlying fundamentals. We exclude these items as we believe them to be infrequent or unusual in nature, but this exclusion is not an indication that similar items may not recur and does not replace net income or net loss as a measure of our overall profitability.

A reconciliation of GAAP financial measures to our non-GAAP financial measures is as follows:

We measure and analyze our segment performance on the basis of "adjusted operating revenue" and "adjusted operating income" or "adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of income due to the exclusion of net realized investment gains and losses as specified in the reconciliations below. These performance measures are in accordance with GAAP guidance for segment reporting, but they should not be viewed as a substitute for total revenue, income before income tax, or net income.

A reconciliation of total revenue to "adjusted operating revenue" and income before income tax to "adjusted operating income" is as follows:

	Three Months Ended June 30						Six Months Ended June 30
	2019			2018			2019			2018
	(in millions of dollars)
Total Revenue	$	3,016.7		$	2,890.3		$	6,004.3		$	5,789.9

Critical Accounting Estimates

We prepare our financial statements in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in our financial statements and accompanying notes. Estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed in our financial statements.

The accounting estimates deemed to be most critical to our financial position and results of operations are those related to reserves for policy and contract benefits, deferred acquisition costs, valuation of investments, pension and postretirement benefit plans, income taxes, and contingent liabilities. There have been no significant changes in our critical accounting estimates during the first six months of 2019.

For additional information, refer to our significant accounting policies in Note 1 of the "Notes to Consolidated Financial Statements" in Part II, Item 8 and "Critical Accounting Estimates" in Part II, Item 7 of our annual report on Form 10-K for the year ended December 31, 2018.

Fluctuations in exchange rates, particularly between the British pound sterling and the U.S. dollar for our U.K. operations, have an effect on our consolidated financial results. In periods when the pound strengthens, translating pounds into dollars increases current period results relative to the prior period. In periods when the pound weakens relative to the preceding period, translating pounds into dollars decreases current period results relative to the prior period.

The weighted average pound/dollar exchange rate for our Unum UK line of business was 1.286 and 1.353 for the three months ended June 30, 2019 and 2018, and 1.296 and 1.373 for the six months ended June 30, 2019 and 2018, respectively. If 2018 results had been translated at the lower exchange rates of 2019, our adjusted operating revenue and adjusted operating income by segment would have both been lower by approximately $9 million and $1 million, respectively, in the second quarter of 2018, and lower by approximately $20 million and $3 million, respectively, in the first six months of 2018. However, it is important to distinguish between translating and converting foreign currency. Except for a limited number of transactions, we do not actually convert pounds into dollars. As a result, we view foreign currency translation as a financial reporting item and not a reflection of operations or profitability in the U.K.

Premium income for the second quarter and first six months of 2019 increased relative to the same periods of 2018, with growth in each of our principal operating business segments, due to overall sales growth, the expansion of our dental and vision products, the addition of our Unum Poland line of business, and generally stable persistency. Premium income continues to decline, as expected, in our Closed Block segment.

Net investment income was generally consistent in the second quarter of 2019 relative to the same period of 2018 but was lower during the first six months of 2019, relative to the same period of 2018, due to a decline in the yield on invested assets and lower miscellaneous investment income, partially offset by an increase in the level of invested assets.

69

There were no other-than-temporary impairment losses on fixed maturity securities included in net realized investment gains and losses for the second quarter of 2019 or 2018, or for the first six months of 2019. We recognized $1.0 million of other-than-temporary impairment losses on fixed maturity securities in net realized investment gains and losses during the first six months of 2018. Also included in net realized investment gains and losses were changes in the fair value of an embedded derivative in a modified coinsurance arrangement, which resulted in realized gains (losses) of $(0.8) million and $(2.3) million in the second quarters of 2019 and 2018, respectively, and $4.7 million and $(4.0) million in the first six months of 2019 and 2018, respectively. See Note 4 in the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further information on realized investment gains and losses.

Other income increased in the second quarter and first six months of 2019 compared to the same periods of 2018 due primarily to growth in our fee-based service products in our Unum US segment, which include family medical leave and administrative services only (ASO) products.

Overall benefits experience was consistent in the second quarter of 2019 and favorable during the first six months of 2019 relative to the same prior year periods. The benefits experience for each of our operating business segments is discussed more fully in "Segment Results" as follows.

Commissions and the deferral of acquisition costs increased in the second quarter and first six months of 2019 relative to the same periods of 2018 driven primarily by sales growth. Growth in the level of the deferred asset in our Unum US and Colonial Life segments and the impact of the prospective unlocking for future experience relative to assumptions in certain of our Colonial life products resulted in higher amortization in the second quarter and first six months of 2019 compared to the same prior year periods. Also contributing to the increase for the first six months was a higher level of policy terminations experienced in the Unum US voluntary benefits line of business.

Interest and debt expense was slightly higher in the second quarter and first six months of 2019 relative to the same periods of 2018 due primarily to a higher level of outstanding debt.

Other expenses, including compensation expense, increased in the second quarter and first six months of 2019 relative to the same periods of 2018, however, the other expense ratio decreased relative to the prior year due to growth in premium income and our continued balancing of investments in the growth of our business with our continued focus on expense management and operating efficiencies.

Our effective income tax rates for the second quarter and first six months of 2019 were 20.1 percent and 20.3 percent of income before income tax, respectively, compared to 19.5 percent and 19.7 percent for the prior year periods. Our effective tax rate differed from the U.S. statutory rate in effect for the second quarter and first six months of 2019 and 2018 primarily due to tax credits.

Consolidated Sales Results

Shown below are sales results for our three principal operating business segments.

(in millions)
	Three Months Ended June 30						Six Months Ended June 30
	2019		% Change		2018		2019		% Change		2018
Unum US	$	221.7	12.1	%	$	197.7	$	500.1	5.9	%	$	472.3
Unum International	$	29.7	4.9	%	$	28.3	$	52.3	15.2	%	$	45.4
Colonial Life	$	126.9	(4.2	)%	$	132.4	$	235.7	(0.2	)%	$	236.1

Sales shown in the preceding chart generally represent the annualized premium income on new sales which we expect to receive and report as premium income during the next 12 months following or beginning in the initial quarter in which the sale is reported, depending on the effective date of the new sale. Sales do not correspond to premium income reported as revenue in accordance with GAAP. This is because new annualized sales premiums reflect current sales performance and what we expect to recognize as premium income over a 12 month period, while premium income reported in our financial statements is reported on an "as earned" basis rather than an annualized basis and also includes renewals and persistency of in-force policies written in prior years as well as current new sales.

Sales, persistency of the existing block of business, employment and salary growth, and the effectiveness of a renewal program are indicators of growth in premium income. Trends in new sales, as well as existing market share, also indicate the potential for growth in our respective markets and the level of market acceptance of price levels and new product offerings. Sales results may fluctuate significantly due to case size and timing of sales submissions.

See "Segment Results" as follows for a discussion of sales by segment.

Premium income in the second quarter and first six months of 2019 increased compared to the same periods of 2018 due to prior period sales growth in both product lines and improved persistency in the group short-term disability product line. Net investment income was lower in the second quarter and first six months of 2019 relative to the same periods of 2018 due to a decline in yield on invested assets, lower miscellaneous investment income, and a decrease in the level of invested assets. Other income increased in the second quarter and first six months of 2019 compared to the same periods of 2018 due to growth in our fee-based service products, which include family medical leave and ASO products.

Benefits experience was favorable in the second quarter and first six months of 2019 relative to the same periods of 2018 due primarily to favorable claim recovery experience in the group long-term disability product line, partially offset by higher paid claim volumes in group short-term disability product line. Also contributing to the favorable benefits experience for the first six months of 2019 relative to the same prior year period was lower claims incidence in the group long-term disability product line.

Commissions and the deferral of acquisition costs were higher in the second quarter and first six months of 2019 compared to the same periods of 2018 due to sales growth. Partially offsetting the increase in the deferral of acquisition costs in the first six months of 2019 relative to the same period of 2018 were lower deferrable costs related to certain sales-based incentive compensation. The amortization of deferred acquisition costs increased in the second quarter and first six months

73

of 2019 relative to the same periods of 2018 due to growth in the level of the deferred asset. Our other expense ratio was slightly higher in the second quarter and first six months of 2019 compared to the same periods of 2018 due to an increase in operational investments in our business balanced with our continued focus on expense management and operating efficiencies.

Premium income increased in the second quarter and first six months of 2019 compared to the same periods of 2018, driven by higher sales, particularly in voluntary benefits and dental and vision. Net investment income was lower in the second quarter and first six months of 2019 relative to the same periods of 2018 due to a decline in yield on invested assets and lower miscellaneous investment income, partially offset by growth in the level of invested assets. Other income is comprised primarily of surrender fees in our voluntary benefits product line.

Benefits experience was less favorable for the individual disability product line in the second quarter and first six months of 2019 compared to the same periods of 2018 due primarily to unfavorable claims activity and less favorable mortality experience. Benefits experience for voluntary benefits in the second quarter and first six months of 2019 was favorable compared to the same periods of 2018 due to favorable claims experience in our disability and hospital indemnity products. Also contributing to the favorable benefit experience for the first six months of 2019 compared to the same period of 2018 was the release of active life reserves resulting from a higher level of policy terminations. Benefits experience for the dental and vision product line in the second quarter and first six months of 2019 was less favorable compared to the same periods of 2018 due to a higher average claims size.

Commissions were slightly higher for the second quarter of 2019 compared to the same period of 2018 due to higher sales. The deferral of acquisition costs for the second quarter and first six months of 2019, as well as commissions for the first six months of 2019, were lower relative to the same periods of 2018 due primarily to a shift in product mix that resulted in lower first-year commissions and a lower corresponding deferral of acquisition costs. The amortization of deferred acquisition costs increased in the second quarter and first six months of 2019 relative to the same periods of 2018 due to the growth in the level of deferred asset across all product lines. Also contributing to the increase in the amortization of deferred acquisition costs in the first six months of 2019 relative to the same period of 2018 was the impact of a higher level of policy terminations, particularly in the voluntary benefits product line. Our other expense ratio decreased in the second quarter and first six months of 2019 compared to the same periods of 2018 due primarily to the timing of certain expenses and our continued focus on expense management and operating efficiencies balanced with operational investments in our business.

Group sales increased in the second quarter and first six months of 2019 compared to the same periods of 2018, primarily driven by an increase in sales to existing customers in both our core market, which we define as employee groups with fewer than 2,000 employees, and our large case market segments. The sales mix in the group market sector for the first six months of 2019 was approximately 56 percent core market and 44 percent large case market.

Individual disability sales, which are primarily concentrated in the multi-life market, decreased in the second quarter and first six months of 2019 compared to the same periods of 2018 driven by lower sales to both new and existing customers. Sales of voluntary benefits increased in the second quarter and first six months of 2019 compared to the same periods of 2018 driven by higher sales to both new and existing customers in the large case market, partially offset by a decrease in sales to both new and existing customers in the core market. Dental and vision sales increased in the second quarter and first six months of 2019 compared to the same periods of 2018, driven by higher sales to both new and existing customers.

Segment Outlook

We remain committed to offering consumers a broad set of financial protection benefit products at the worksite. We will continue to invest in a unique customer experience defined by simplicity, empathy, and deep industry expertise through the re-design of our processes and the increased utilization of digital capabilities and technology to enhance enrollment, underwriting, and claims processing. We will continue to focus on the expansion of products, which includes dental and vision, medical stop-loss, and leave management services, while also introducing new voluntary benefits products. Additionally, we will focus on client expansion, consumer engagement, and collaborative partnerships, all underpinned by strong risk management. We believe our active client management and differentiated integrated customer experience across our product lines will continue to enable us to grow our market.

We anticipate continued stable adjusted operating income growth in 2019, with disciplined sales and premium growth, consistent risk management, and improving operational efficiency. We believe our underlying profitability will remain strong throughout the year, driven primarily by our continued product mix shift, expense efficiencies, and consistent operating effectiveness.

The low interest rate environment continues to place pressure on our profit margins by impacting net investment income yields as well as discount rates on our insurance liabilities. Our net investment income may continue to be unfavorably impacted by fluctuations in miscellaneous investment income and lower asset levels resulting from improved capital efficiency.  As part of our pricing discipline and our reserving methodology, we continuously monitor emerging interest rate experience and adjust our pricing and reserve discount rates, as appropriate. We expect that our underwriting results for the remainder of 2019 will continue at a level generally consistent with 2018. We continuously monitor key indicators to assess our risks and attempt to adjust our business plans accordingly.

Foreign Currency Translation

The functional currencies of Unum UK and Unum Poland are the British pound sterling and Polish zloty, respectively. Premium income, net investment income, claims, and expenses are received or paid in the functional currency, and we hold functional currency-denominated assets to support functional currency-denominated policy reserves and liabilities. We translate functional currency-denominated financial statement items into dollars for our consolidated financial reporting. We translate income statement items using an average exchange rate for the reporting period, and we translate balance sheet items using the exchange rate at the end of the period. We report unrealized foreign currency translation gains and losses in accumulated other comprehensive income in our consolidated balance sheets.

Fluctuations in exchange rates have an effect on Unum International's reported financial results and our consolidated financial results. In periods when the functional currency strengthens relative to the preceding period, translation increases current period results relative to the prior period. In periods when the functional currency weakens, translation decreases current period results relative to the prior period.

Premium income increased in the second quarter and first six months of 2019 compared to the same periods of 2018 driven by higher overall persistency, sales growth, and the impact of rate increases in the group long-term disability product line.

Net investment income was higher in the second quarter and first six months of 2019 relative to the same prior year periods due to higher miscellaneous investment income, resulting from a higher than normal level of bond calls, and a higher level of invested assets, partially offset by a lower yield on fixed-rate bonds. Investment income from inflation index-linked bonds, which we invest in to support the claim reserves associated with certain of our group policies that provide for inflation-linked increases in benefits, was higher in the second quarter of 2019 but lower in the first six months of 2019 relative to the same

79

periods of 2018. The change in net investment income attributable to these index-linked bonds is generally offset by a change in the reserves for future claims payments related to the inflation index-linked group long-term disability and group life policies.

Benefits experience was unfavorable in the second quarter and first six months of 2019 relative to the same prior year periods due to unfavorable mortality experience and a reduction in the claim reserve discount rate to recognize the impact on future portfolio yields from the higher than normal level of bond calls experienced during the second quarter of 2019. The comparison for the second quarter and first six months of 2019 relative to the same prior year periods was also impacted by inflation-linked movements in benefits related to our group products.

Commissions decreased slightly in the second quarter and first six months of 2019 relative to the same prior year periods due primarily to a lower commission rate in certain products, partially offset by higher overall sales. The deferral of acquisition costs was consistent in the second quarter and first six months of 2019 relative to the same prior year periods. The amortization of deferred acquisition costs decreased in the second quarter and first six months of 2019 relative to the same prior year periods due a decline in the level of the deferred asset. The other expense ratio was lower for the second quarter and first six months of 2019 relative to the prior year periods due to the increase in premium income and our continued focus on expense management and operating efficiencies.

The following discussion of sales results relates only to our Unum UK product lines and is based on functional currency.

Group long-term disability sales decreased during the second quarter and first six months of 2019 relative to the same periods of 2018, with lower sales to new customers in our core market, which we define as employee groups with fewer than 500 employees, and lower sales to existing customers in both our core and large case markets. Partially offsetting the decrease during the second quarter of 2019 compared to the same period of 2018 were higher sales to new customers in the large case market.

Group life sales were higher in the second quarter and first six months of 2019 relative to the same periods of 2018, with an increase in sales to new customers in both the core and large case markets and an increase in sales to existing customers in the core market. Partially offsetting the increase during the second quarter of 2019 compared to the same period of 2018 were lower sales to existing customers in the large case market.

Supplemental sales increased during the second quarter of 2019 relative to the same period of 2018 due to higher sales in the group critical illness product line. Supplemental sales were higher during the first six months of 2019 compared to the same prior year period due to higher sales in the group critical illness product line, partially offset by lower sales in the dental product line.

Segment Outlook

We are committed to driving growth in the Unum International segment and will build on the capabilities that we believe will generate growth and profitability in our businesses. Expanding our Unum UK group long-term disability market position remains a significant priority. Completing the integration of our Unum Poland business and growing that business through the expansion of its product offerings is also a significant opportunity. Other key priorities, specifically for our Unum UK business, include the continued disciplined implementation of price increases across interest sensitive product lines, which has been successful in offsetting pressure from lower interest rates and heightened disability claims experience, while maintaining solid persistency results and continuing to follow a disciplined approach to new sales activity in the competitive pricing environment. We intend to build upon the strong sales momentum we have seen in our group critical illness and dental products through increased participation rates as well as accelerate growth in our group life line of business. We have simplified our processes and operations to deliver efficiencies and further improvements to customer service and remain focused on risk discipline. The investments that we have made in the operating model for our UK business have significantly improved our operational effectiveness and we will continue to reinvest a portion of these expense savings to build marketing and digital capabilities, which we believe will drive sustainable growth through the development of new distribution capabilities and reaching new customers.

Negotiations regarding the U.K.'s formal notice to withdraw from the EU are continuing to generate uncertainty in the U.K. economy. The magnitude and longevity of potential negative economic impacts on our growth will depend on the agreements reached by the U.K. and EU as a result of exit negotiations and the resulting response of the U.K. marketplace, but we believe we are well positioned to capitalize on future growth opportunities as these negotiations are resolved and the operating environment improves. Overall, we expect the economic conditions experienced in 2018 to continue for the U.K., with lower economic growth, wage inflation, and interest rates presenting challenges in the short to medium term.

We expect the current environment to continue to have a negative impact on our growth expectations in the near-term and may also lead to a higher rate of claim incidence, lower levels of claim recoveries, or lower claim discount rates. As part of our continued pricing discipline and our reserving strategy, we continuously monitor emerging interest rate experience and adjust our pricing and reserve discount rates, as appropriate. We will likely continue to experience volatility in net investment income and our benefit ratio due to fluctuations in the level of inflation in the U.K., however, we do not expect this to have a significant impact on adjusted operating income. There are no indications currently that capital requirements for our U.K. operations will change, but economic conditions may in the near term cause volatility in our solvency ratios. We continuously monitor key indicators to assess our risks and attempt to adjust our business plans accordingly to respond to external challenges.

Premium income increased in the second quarter and first six months of 2019 relative to the same periods of 2018 due to growth in the in-force block resulting from prior period sales growth, which includes the expansion of our dental and vision products, offset partially by a lower level of persistency. Net investment income declined in the second quarter and first six months of 2019 compared to the same periods of 2018 due to lower miscellaneous investment income and a lower yield on invested assets, partially offset by an increase in the level of invested assets.

Benefits experience in the second quarter of 2019 was unfavorable compared to the same period of 2018, driven primarily by higher claims incidence in our cancer and critical illness line of business, partially offset by lower claims incidence in our life line of business. Benefits experience in the first six months of 2019 was generally consistent with the same period of 2018.

Commissions and the deferral of acquisition costs were higher in the second quarter and first six months of 2019 relative to the same periods of 2018 due to prior period sales growth. The amortization of deferred acquisition costs increased during the second quarter and first six months of 2019 relative to the same periods of 2018 due to growth in the level of the deferred asset and the impact of the prospective unlocking for future experience relative to assumptions for our interest-sensitive voluntary life products. The other expense ratio was lower in the second quarter and first six months of 2019, due to an increase in premium income and our continued focus on expense management and operating efficiencies.

Commercial market sales decreased in the second quarter and first six months of 2019 as compared to the same periods of 2018, due to lower sales to new customers in both the core market, which we define as accounts with fewer than 1,000 employees, and the large case market, partially offset by higher sales to existing customers in the core and large case markets. Also impacting the comparison for the first six months of 2019 compared to the same period of 2018 were higher dental and vision sales. Public sector market sales were lower in the second quarter of 2019 due primarily to a decline in sales to new and existing customers but were higher during the first six months of 2019 compared to the same period of 2018 due to higher sales to new customers, particularly in the first quarter of 2019. The number of new accounts decreased 9.4 percent and 3.6 percent, respectively, in the second quarter and first six months of 2019 relative to the same periods of 2018. The average new case size decreased 6.6 percent and 6.2 percent, respectively, in the second quarter and first six months of 2019 relative to the same periods of 2018.

Segment Outlook

We remain committed to providing employees and their families with simple, modern, and personal benefit solutions. We will continue to focus on expanding our distribution system through the growth and development of our agency sales force and establishing effective broker partnerships. We will also invest in new solutions and digital capabilities to enhance the customer experience for our business partners and further improve productivity. We will seek to capitalize on the expansion of our new dental products, which we believe will create opportunities for new cases while also allowing for further cross-selling opportunities to existing clients. We will continue to focus on accelerating growth through territory expansion, territory growth, persistency investments, and increased participation rates. We believe our distribution system, customer service capabilities, the expansion of our new dental products, and ability to serve all market sizes position us well for future growth. 

We expect to see growth in sales, premium, and adjusted operating earnings in 2019. We also anticipate a decline in the operating expense ratio as we continue to balance operating efficiencies with the continued investments in future growth. The lower interest rate environment will continue to have an unfavorable impact on our profit margins, and volatility in miscellaneous investment income is likely to continue.  We expect our annual benefit ratio for 2019 to be generally consistent with the level of 2018. While we believe our underlying profitability will remain strong, current economic conditions and increasing competition in the voluntary workplace market are seen as external risks to achievement of our business plans.  We continuously monitor key indicators to assess our risks and attempt to adjust our business plans accordingly.

Closed Block Segment

The Closed Block segment consists of individual disability, group and individual long-term care, and other insurance products no longer actively marketed. Individual disability in this segment generally consists of policies we sold prior to the mid-1990s and entirely discontinued selling in 2004. We discontinued offering individual long-term care in 2009 and group long-term care in 2012. Other insurance products include group pension, individual life and corporate-owned life insurance, reinsurance pools and management operations, and other miscellaneous product lines.

Premium income for individual disability decreased in the second quarter and first six months of 2019 compared to the same periods of 2018 due to policy terminations and maturities. Premium income for long-term care in the second quarter and first six months of 2019 was slightly higher than the same prior year periods, with rate increases mostly offset by policy terminations. We continue to file requests with various state insurance departments for premium rate increases on certain of our individual and group long-term care policies which reflect assumptions as of the date of filings.  In states for which a rate increase is submitted and approved, we routinely provide customers options for coverage changes or other approaches that might fit their current financial and insurance needs.

85

Net investment income was higher in the second quarter and first six months of 2019 relative to the same periods of 2018 due to an increase in the level of invested assets, partially offset by lower miscellaneous investment income. Also offsetting the increase in net investment income during the second quarter of 2019 was a decline in yield on invested assets. Other income, which includes the underlying results and associated net investment income of certain blocks of individual disability reinsured business, continues to decline due to expected terminations and maturities.

Individual disability benefits experience was favorable in the second quarter of 2019 compared to the same period of 2018 primarily due to a reduction in the claim reserve discount rate to recognize the impact on future portfolio yields resulting from an increased level of miscellaneous investment income in the second quarter of 2018, partially offset by higher claims incidence in the second quarter of 2019. During the first six months of 2019, individual disability benefits experience was unfavorable relative to the same prior year period due primarily to higher average claims size. Long-term care benefits experience in the second quarter and first six months of 2019 was not comparable to the same periods of 2018 due to the previously discussed update in our assumptions during the third quarter of 2018, but was consistent with our expectations. The interest adjusted loss ratio for the period subsequent to the update in our assumptions was 86.7 percent.

The other expense ratio was higher in the second quarter and first six months of 2019 compared to the same periods of 2018 due to the expected decline in premium income for individual disability, partially offset by our continued focus on expense management and operating efficiencies.

Segment Outlook

We will continue to execute on our well-defined strategy of implementing long-term care premium rate increases, efficient capital management, improved financial analysis, and operational effectiveness. Despite continued anticipated premium rate increases in our long-term care business, we expect overall premium income and adjusted operating revenue to decline over time as these closed blocks of business wind down. We will likely experience volatility in net investment income due to fluctuations of miscellaneous investment income and the increased allocation towards alternative assets in the long-term care product line portfolio. We continuously monitor key indicators to assess our risks and attempt to adjust our business plans accordingly.

Profitability of our long-tailed products is affected by claims experience related to mortality and morbidity, resolutions, investment returns, premium rate increases, and persistency.  We believe that the interest adjusted loss ratios for the individual disability and long-term care lines of business will be relatively flat over the long term, but these product lines may continue to experience quarterly volatility, particularly in the near term for our long-term care product lines as our claim block matures and as we continue the implementation of premium rate increases. Specific to our long-term care line of business, which is in loss recognition and should report levels of benefits plus operating expenses that equal the gross premium reported, we expect the long term interest adjusted loss ratio to be in the 85 to 90 percent range with some quarterly volatility. Claim resolution rates, which measure the resolution of claims from recovery, deaths, settlements, and benefit expirations, are very sensitive to operational and external factors and can be volatile. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the life of the block of business and will vary from actual experience in any one period. It is possible that variability in any of our reserve assumptions, including, but not limited to, interest rates, mortality, morbidity, resolutions, premium rate increases, benefit change elections, and persistency, could result in a material impact on the adequacy of our reserves, including adjustments to reserves established under loss recognition.

Corporate Segment

The Corporate segment includes investment income on corporate assets not specifically allocated to a line of business, interest expense on corporate debt other than non-recourse debt, and certain other corporate income and expenses not allocated to a line of business.

Net investment income was lower in the second quarter and first six months of 2019 relative to the same periods of 2018 due to a lower level of invested assets, a decrease in yield on invested assets, and lower miscellaneous investment income.

Interest and other expenses were higher in the second quarter and first six months of 2019 relative to the same periods of 2018 due to higher pension costs and a higher level of outstanding debt.

Segment Outlook

We expect to continue to generate excess capital on an annual basis through the statutory earnings in our insurance subsidiaries, aided in part by the reduction in the corporate tax rate resulting from tax reform. We believe we are well positioned with flexibility to preserve our capital strength while also continuing to return capital to our shareholders.

87

Investments

Overview

Investment activities are an integral part of our business, and profitability is significantly affected by investment results. We segment our invested assets into portfolios that support our various product lines. Generally, our investment strategy for our portfolios is to match the effective asset cash flows and durations with related expected liability cash flows and durations to consistently meet the liability funding requirements of our businesses. We seek to earn investment income while assuming credit risk in a prudent and selective manner, subject to constraints of quality, liquidity, diversification, and regulatory considerations. Our overall investment philosophy is to invest in a portfolio of high quality assets that provide investment returns consistent with that assumed in the pricing of our insurance products. Assets are invested predominately in fixed maturity securities. Changes in interest rates may affect the amount and timing of cash flows.

We actively manage our asset and liability cash flow match and our asset and liability duration match to limit interest rate risk. We may redistribute investments among our different lines of business, when necessary, to adjust the cash flow and/or duration of the asset portfolios to better match the cash flow and duration of the liability portfolios. Asset and liability portfolio modeling is updated on a quarterly basis and is used as part of the overall interest rate risk management strategy. Cash flows from the in-force asset and liability portfolios are projected at current interest rate levels and also at levels reflecting an increase and a decrease in interest rates to obtain a range of projected cash flows under the different interest rate scenarios. These results enable us to assess the impact of projected changes in cash flows and duration resulting from potential changes in interest rates. Testing the asset and liability portfolios under various interest rate scenarios enables us to choose what we believe to be the most appropriate investment strategy, as well as to limit the risk of disadvantageous outcomes. Although we test the asset and liability portfolios under various interest rate scenarios as part of our modeling, the majority of our liabilities related to insurance contracts are not interest rate sensitive, and we therefore have minimal exposure to policy withdrawal risk. Our determination of investment strategy relies on long-term measures such as reserve adequacy analysis and the relationship between the portfolio yields supporting our various product lines and the aggregate discount rate assumptions embedded in the reserves. We also use this analysis in determining hedging strategies and utilizing derivative financial instruments for managing interest rate risk and the risk related to matching duration for our assets and liabilities. We do not use derivative financial instruments for speculative purposes.

Our investment portfolio is well diversified by type of investment and industry sector. We have established an investment strategy that we believe will provide for adequate cash flows from operations and allow us to hold our securities through periods where significant decreases in fair value occur. We believe our emphasis on risk management in our investment portfolio, including credit and interest rate management, has positioned us well and generally reduced the volatility in our results.

The following two tables show the length of time our investment-grade and below-investment-grade fixed maturity securities had been in a gross unrealized loss position as of June 30, 2019 and at the end of the prior four quarters. The relationships of the current fair value to amortized cost are not necessarily indicative of the fair value to amortized cost relationships for the securities throughout the entire time that the securities have been in an unrealized loss position nor are they necessarily indicative of the relationships after June 30, 2019. The decrease in the unrealized loss on fixed maturity securities during the second quarter of 2019 was due primarily to a decrease in U.S. treasury rates.

At June 30, 2019, we held two below-investment-grade fixed maturity securities with a gross unrealized loss greater than $10.0 million.  One security is related to a global pharmaceutical company and had a fair value of $60.3 million and a gross unrealized loss of $16.7 million. The other security is related to a U.S. based oil and natural gas producer and had a fair value of $13.7 million and a gross unrealized loss of $10.7 million. We intend to and have the ability to continue to hold these securities to maturity and believe that the declines in fair value are temporary.

During the second quarter of 2019, we recognized a realized loss of $15.6 million on the sale of securities of a U.S. based oil and natural gas producer. The company has been impacted by the significant decline in energy prices, a high level of debt, and an inability to complete certain asset sales. At the time of disposition, these securities had been in an unrealized loss position for a period of greater than three years.

We had no individual realized investment losses of $10.0 million or greater from the sale of fixed maturity securities during the second quarter or first six months of 2018. We had no individual realized investment losses of $10.0 million or greater from other-than-temporary impairments during the second quarters or first six months of 2019 or 2018.

At June 30, 2019, our mortgage/asset-backed securities had an average life of 5.60 years, effective duration of 4.70 years, and a weighted average credit rating of Aaa. The mortgage/asset-backed securities are valued on a monthly basis using valuations supplied by the brokerage firms that are dealers in these securities as well as independent pricing services. One of the risks involved in investing in mortgage/asset-backed securities is the uncertainty of the timing of cash flows from the underlying loans due to prepayment of principal with the possibility of reinvesting the funds in a lower interest rate environment. We use models which incorporate economic variables and possible future interest rate scenarios to predict future prepayment rates. The timing of prepayment cash flows may also cause volatility in our recognition of investment income. We recognize investment income

91

on these securities using a constant effective yield based on projected prepayments of the underlying loans and the estimated economic life of the securities.  Actual prepayment experience is reviewed periodically, and effective yields are recalculated when differences arise between prepayments originally projected and the actual prepayments received and currently projected. The effective yield is recalculated on a retrospective basis, and the adjustment is reflected in net investment income.

We have no exposure to subprime mortgages, "Alt-A" loans, or collateralized debt obligations in our investment portfolios. We have not invested in mortgage-backed derivatives, such as interest-only, principal-only, or residuals, where market values can be highly volatile relative to changes in interest rates. The credit quality of our mortgage-backed securities portfolio has not been negatively impacted by the issues in the market concerning subprime mortgage loans. The change in value of our mortgage-backed securities portfolio has moved in line with that of prime agency-backed mortgage-backed securities.

As of June 30, 2019, the amortized cost and fair value of our below-investment-grade fixed maturity securities was $3,178.1 million and $3,207.4 million, respectively. Below-investment-grade securities are inherently riskier than investment-grade securities since the risk of default by the issuer, by definition and as exhibited by bond rating, is higher. Also, the secondary market for certain below-investment-grade issues can be highly illiquid. Additional downgrades may occur, but we do not anticipate any liquidity problems resulting from our investments in below-investment-grade securities, nor do we expect these investments to adversely affect our ability to hold our other investments to maturity.

Fixed Maturity Securities - Foreign Exposure

Our investments in issuers in foreign countries are chosen for specific portfolio management purposes, including asset and liability management and portfolio diversification across geographic lines and sectors to minimize non-market risks. In our approach to investing in fixed maturity securities, specific investments within approved countries and industry sectors are evaluated for their market position and specific strengths and potential weaknesses.  For each security, we consider the political, legal, and financial environment of the sovereign entity in which an issuer is domiciled and operates. The country of domicile is based on consideration of the issuer's headquarters, in addition to location of the assets and the country in which the majority of sales and earnings are derived.  We do not have exposure to foreign currency risk, as the cash flows from these investments are either denominated in currencies or hedged into currencies to match the related liabilities. We continually evaluate our foreign investment risk exposure.

Mortgage Loans

Our mortgage loan portfolio was $2,218.9 million and $2,295.0 million on an amortized cost basis at June 30, 2019 and December 31, 2018, respectively. Our mortgage loan portfolio is comprised entirely of commercial mortgage loans. We believe our mortgage loan portfolio is well diversified geographically and among property types. The incidence of problem mortgage loans and foreclosure activity continues to be low. Due to conservative underwriting, we expect the level of problem loans to remain low relative to the industry. We held no impaired mortgage loans at June 30, 2019. We held one impaired mortgage loan at December 31, 2018 with a net realizable value of $3.4 million, net of a valuation allowance of $0.2 million. During the first quarter of 2019, the impaired mortgage loan was settled, and we recognized an additional loss of $0.1 million.

Derivative Financial Instruments

We use derivative financial instruments primarily to manage reinvestment, duration, foreign currency, and credit risks. Historically, we have utilized current and forward interest rate swaps and options on forward interest rate swaps and U.S. Treasury rates, current and forward currency swaps, forward treasury locks, currency forward contracts, forward contracts on specific fixed income securities, and credit default swaps. Credit exposure on derivatives is limited to the value of those contracts in a net gain position, including accrued interest receivable less collateral held. At June 30, 2019, we had no credit exposure on derivatives. We held $22.3 million of cash collateral from our counterparties at June 30, 2019. The carrying value of fixed maturity securities posted as collateral to our counterparties was $30.4 million at June 30, 2019. We had no cash collateral posted to our counterparties at June 30, 2019. We believe that our credit risk is mitigated by our use of multiple counterparties, all of which have an investment-grade credit rating, and by our use of cross-collateralization agreements.

Other

Our exposure to non-current investments, defined as foreclosed real estate and invested assets which are delinquent as to interest and/or principal payments, totaled $35.9 million and $36.0 million on a fair value basis at June 30, 2019 and December 31, 2018, respectively.

For further information see "Investments" in Part I, Item 1 and "Critical Accounting Estimates" and "Investments" in Part II, Item 7 of our annual report on Form 10-K for the year ended December 31, 2018, and Notes 4 and 5 of the "Notes to Consolidated Financial Statements" contained herein in Item 1.

Liquidity and Capital Resources

Overview

Our liquidity requirements are met primarily by cash flows provided from operations, principally in our insurance subsidiaries. Premium and investment income, as well as maturities and sales of invested assets, provide the primary sources of cash. Debt and/or securities offerings provide additional sources of liquidity. Cash is applied to the payment of policy benefits, costs of acquiring new business (principally commissions), operating expenses, and taxes, as well as purchases of new investments.

We have established an investment strategy that we believe will provide for adequate cash flows from operations. We attempt to match our asset cash flows and durations with expected liability cash flows and durations to meet the funding requirements of our business. However, deterioration in the credit market may delay our ability to sell our positions in certain of our fixed maturity securities in a timely manner and adversely impact the price we receive for such securities, which may negatively impact our cash flows. Furthermore, if we experience defaults on securities held in the investment portfolios of our insurance subsidiaries, this will negatively impact statutory capital, which could reduce our insurance subsidiaries' capacity to pay dividends to our holding companies. A reduction in dividends to our holding companies could force us to seek external financing to avoid impairing our ability to pay dividends to our stockholders or meet our debt and other payment obligations.

Our policy benefits are primarily in the form of claim payments, and we have minimal exposure to the policy withdrawal risk associated with deposit products such as individual life policies or annuities. A decrease in demand for our insurance products or an increase in the incidence of new claims or the duration of existing claims could negatively impact our cash flows from operations. However, our historical pattern of benefits paid to revenues is generally consistent, even during cycles of economic downturns, which serves to minimize liquidity risk.

The liquidity requirements of the holding company Unum Group include common stock dividends, interest and debt service, acquisitions, and ongoing investments in our businesses. Unum Group's liquidity requirements are met by assets held by Unum Group and our intermediate holding companies, dividends from primarily our insurance subsidiaries, and issuance of common stock, debt, or other capital securities and borrowings from existing credit facilities, as needed. As of June 30, 2019, Unum Group and our intermediate holding companies held fixed maturity securities, short-term investments, and cash of $977 million. Fixed maturity securities consisted primarily of mortgage/asset-backed securities with an average maturity date of 4.5 years. Short-term investments consisted primarily of commercial paper.  No significant restrictions exist on our ability to use or access funds in any of our U.S. or foreign intermediate holding companies. Future amounts repatriated from our foreign subsidiaries are eligible for a 100 percent exemption from U.S. income tax but may be subject to tax on foreign currency gain or loss.

As part of our capital deployment strategy, we repurchase shares of Unum Group's common stock, as authorized by our board of directors. Our current share repurchase program was approved by our board of directors in May 2019 and authorizes the repurchase of up to $750 million of common stock through November 2020, with the pace of repurchase activity to depend upon various factors such as the level of available cash, alternative uses for cash, and our stock price. This new authorization replaced the previous authorization of $750 million that was scheduled to expire in November 2019. During the first six months of 2019, we repurchased 5.6 million shares at a cost of approximately $200 million. The dollar value of shares remaining under the current repurchase program was approximately $716 million at June 30, 2019. See Note 10 of the "Notes to Consolidated Financial Statements" contained herein in Item 1.

Cash Available from Subsidiaries

Unum Group and certain of its intermediate holding company subsidiaries depend on payments from subsidiaries to pay dividends to stockholders, to pay debt obligations, and/or to pay expenses. These payments by our insurance and non-insurance subsidiaries may take the form of dividends, operating and investment management fees, and/or interest payments on loans from the parent to a subsidiary.

Restrictions under applicable state insurance laws limit the amount of dividends that can be paid to a parent company from its insurance subsidiaries in any 12-month period without prior approval by regulatory authorities. For life insurance companies domiciled in the U.S., that limitation generally equals, depending on the state of domicile, either ten percent of an insurer's statutory surplus with respect to policyholders as of the preceding year end or the statutory net gain from operations, excluding realized investment gains and losses, of the preceding year. The payment of dividends to a parent company from a life insurance subsidiary is generally further limited to the amount of unassigned funds.

Certain of our domestic insurance subsidiaries cede blocks of business to Northwind Reinsurance Company (Northwind Re) and Fairwind Insurance Company (Fairwind), both of which are affiliated captive reinsurance subsidiaries domiciled in the United States with Unum Group as the ultimate parent. The ability of Northwind Re and Fairwind to pay dividends to their respective parent companies will depend on their satisfaction of applicable regulatory requirements and on the performance of the business reinsured by Northwind Re and Fairwind.

The ability of Unum Group and certain of its intermediate holding company subsidiaries to continue to receive dividends from their insurance subsidiaries also depends on additional factors such as RBC ratios and capital adequacy and/or solvency requirements, funding growth objectives at an affiliate level, and maintaining appropriate capital adequacy ratios to support desired ratings. The RBC ratios for our U.S. insurance subsidiaries at June 30, 2019 are in line with our expectations and are significantly above the level that would require state regulatory action.

Unum Group and/or certain of its intermediate holding company subsidiaries may also receive dividends from our U.K. subsidiaries, the payment of which may be subject to applicable insurance company regulations and capital guidance in the U.K. Unum Limited is subject to the requirements of Solvency II, a European Union (EU) directive, which prescribes capital requirements and risk management standards for the European insurance industry.  Our European holding company is also subject to the Solvency II requirements relevant to insurance holding companies, while its subsidiaries (the Unum European Economic Area (EEA) Group), which includes Unum Limited, are subject to group supervision under Solvency II. The Unum EEA Group received approval from the U.K. Prudential Regulation Authority to use its own internal model for calculating regulatory capital and also received approval for certain associated regulatory permissions including transitional relief as the Solvency II capital regime continues to be implemented. There are currently no indications that capital requirements for the Unum EEA Group will change as a result of the U.K.'s exit from the EU, but economic conditions may in the near term cause volatility in our solvency ratios.

The payment of dividends to the parent company from our subsidiaries also requires the approval of the individual subsidiary's board of directors.

During the remainder of 2019, we intend to maintain a level of capital in our insurance subsidiaries above the applicable capital adequacy requirements and minimum solvency margins.

Insurance regulatory restrictions do not limit the amount of dividends available for distribution from non-insurance subsidiaries except where the non-insurance subsidiaries are held directly or indirectly by an insurance subsidiary and only indirectly by Unum Group.

Funding for Employee Benefit Plans

During the first six months of 2019, we made contributions of $35.2 million and £1.7 million to our U.S. and U.K. defined contribution plans, respectively, and expect to make additional contributions of approximately $40 million and £1.5 million during the remainder of 2019. We do not expect to make contributions to our U.S. or U.K. qualified defined benefit pension plans during 2019. We have met all minimum pension funding requirements set forth by the Employee Retirement Income Security Act. We have estimated our future funding requirements under the Pension Protection Act of 2006 and under applicable U.K. law and do not believe that any future funding requirements will cause a material adverse effect on our liquidity.

94

Debt

Our long-term debt balance at June 30, 2019 was $3,341.2 million, net of deferred debt issuance costs of $33.0 million, and consisted primarily of secured and unsecured senior notes and junior subordinated debt securities.

Northwind Holdings made principal payments on its floating rate, senior secured non-recourse notes of $30.0 million in the first six months of 2019.

In June 2019, we issued $400.0 million of 4.00% senior notes due 2029. The notes are callable at or above par and rank equally in the right of payment with all of our other unsecured and unsubordinated debt. The net proceeds of the offering are expected to be used for general corporate purposes, including the repayment at maturity of our outstanding 5.625% senior notes due September 2020.

In April 2019, we amended the terms of our existing five-year unsecured revolving credit facility, increasing it from $400.0 million to $500.0 million. The credit facility, which was previously set to expire in 2021, was extended through April 2024. Under the terms of the amended agreement, we may request that the credit facility be increased up to $700.0 million, up from the previous amount of $600.0 million. We also may request, on up to two occasions, that the lenders' commitment termination dates be extended by one year. The credit facility provides for the issuance of letters of credit subject to certain terms and limitations. At June 30, 2019, letters of credit totaling $2.0 million had been issued from the credit facility, but there were no borrowed amounts outstanding.

Also in April 2019, we separately entered into a three-year $100.0 million unsecured revolving credit facility with a different syndicate of lenders, which is set to expire in April 2022. Under the terms of the agreement, we may request that the credit facility be increased up to $140.0 million. We also may request that the lenders' commitment termination dates be extended by one year. The credit facility provides for the issuance of letters of credit subject to certain terms and limitations. At June 30, 2019, there have been no letters of credit issued from the credit facility and there were no borrowed amounts outstanding.

There are no significant financial covenants associated with any of our outstanding debt obligations.  We continually monitor our compliance with our debt covenants and remain in compliance. Our credit facilities include financial covenants that place limitations on our leverage ratio and consolidated net worth. The credit facilities also include covenants that limit subsidiary indebtedness. We have not observed any current trends that would cause a breach of any debt covenants. See Note 13 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 and "Debt" and Note 8 of the "Notes to Consolidated Financial Statements" contained in Part II, Items 7 and 8, respectively, of our annual report on Form 10-K for the year ended December 31, 2018 for further discussion.

Commitments

At June 30, 2019, we had unfunded unconditional commitments of $2.3 million to fund tax credit partnership investments, and $14.7 million to fund the purchase of transferable state tax credits. These commitments are recognized as liabilities in our consolidated balance sheets, with a corresponding recognition of other long-term investments and other assets, respectively. In addition, we had commitments of $103.5 million to fund certain investments in private placement fixed maturity securities, $369.2 million to fund certain private equity partnerships, and $87.1 million to fund certain commercial mortgage loans, which may or may not be funded.

With respect to our commitments and off-balance sheet arrangements, see the discussion under "Commitments" in Part II, Item 7 of our annual report on Form 10-K for the year ended December 31, 2018. During the first six months of 2019, there were no substantive changes in our commitments, contractual obligations, or other off-balance sheet arrangements other than the changes noted herein.

Transfers of Financial Assets

Our investment policy permits us to lend fixed maturity securities to unaffiliated financial institutions in short-term securities lending agreements, which increases our investment income with minimal risk. We account for all of our securities lending agreements and repurchase agreements as secured borrowings. We had $5.8 million of securities lending agreements outstanding at June 30, 2019 which were collateralized by cash and reported as payables for collateral on investments in our consolidated balance sheets. The cash received as collateral was reinvested in short-term investments. The average balance during the first six months of 2019 was $2.0 million, and the maximum amount outstanding at any month end was $5.9 million. In addition, at June 30, 2019, we had $274.5 million of off-balance sheet securities lending agreements which were collateralized

95

by securities that we were neither permitted to sell nor control. The average balance of these off-balance sheet transactions during the first six months of 2019 was $201.7 million, and the maximum amount outstanding at any month end was $274.5 million.

To manage our cash position more efficiently, we may enter into repurchase agreements with unaffiliated financial institutions. We generally use repurchase agreements as a means to finance the purchase of invested assets or for short-term general business purposes until projected cash flows become available from our operations or existing investments. We had no repurchase agreements outstanding at June 30, 2019, nor did we utilize any repurchase agreements during the first six months of 2019. Our use of repurchase agreements and securities lending agreements can fluctuate during any given period and will depend on our liquidity position, the availability of long-term investments that meet our purchasing criteria, and our general business needs.

Certain of our U.S. insurance subsidiaries are members of regional Federal Home Loan Banks (FHLB). As of June 30, 2019, we owned $18.5 million of FHLB common stock and had no outstanding advances from the regional FHLBs.

See Note 4 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further information.

Consolidated Cash Flows

(in millions of dollars)
	Six Months Ended June 30
	2019			2018
Net Cash Provided by Operating Activities	$	942.7		$	696.2
Net Cash Used by Investing Activities	(1,007.2		)	(601.6		)
Net Cash Provided (Used) by Financing Activities	31.3			(72.5		)
Net Increase (Decrease) in Cash and Bank Deposits	$	(33.2	)	$	22.1

Operating Cash Flows

Operating cash flows are primarily attributable to the receipt of premium and investment income, offset by payments of claims, commissions, expenses, and income taxes. Premium income growth is dependent not only on new sales, but on policy renewals and growth of existing business, renewal price increases, and persistency. Investment income growth is dependent on the growth in the underlying assets supporting our insurance reserves and capital and on the earned yield. The level of commissions and operating expenses is attributable to the level of sales and the first year acquisition expenses associated with new business as well as the maintenance of existing business. The level of paid claims is affected partially by the growth and aging of the block of business and also by the general economy, as previously discussed in the operating results by segment.

Investing Cash Flows

Investing cash inflows consist primarily of the proceeds from the sales and maturities of investments.  Investing cash outflows consist primarily of payments for purchases of investments.  Our investment strategy is to match the cash flows and durations of our assets with the cash flows and durations of our liabilities to meet the funding requirements of our business. When market opportunities arise, we may sell selected securities and reinvest the proceeds to improve the yield and credit quality of our portfolio. We may at times also sell selected securities and reinvest the proceeds to improve the duration matching of our assets and liabilities and/or re-balance our portfolio. As a result, sales before maturity may vary from period to period. The sale and purchase of short-term investments is influenced by proceeds received from issuance of debt, our securities lending program, and by the amount of cash which is at times held in short-term investments to facilitate the availability of cash to fund the purchase of appropriate long-term investments, repay maturing debt, fund acquisitions, and/or to fund our capital deployment program.

See Note 4 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 for further information.

Financing Cash Flows

Financing cash flows consist primarily of borrowings and repayments of debt, issuance or repurchase of common stock, and dividends paid to stockholders.

In June 2019, we issued $400.0 million of 4.00% senior notes due 2029 and received total proceeds of $395.9 million.

96

During each of the first six months of 2019 and 2018, we made principal payments of $30.0 million on our senior secured non-recourse notes issued by Northwind Holdings.

In May 2018, we issued $300.0 million of 6.25% junior subordinated notes due 2058 and received total proceeds of $290.7 million.

Cash used to repurchase shares of Unum Group's common stock during the first six months of 2019 and 2018 was $200.2 million and $205.8 million, respectively, with a portion of the cash used in 2018 related to the settlement of amounts due on shares purchased in the fourth quarter 2017. During the first six months of 2019 and 2018, we paid dividends of $110.9 million and $103.3 million, respectively, to holders of Unum Group's common stock.

See Notes 10 and 13 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 and "Debt" contained in this Item 2 for further information.

Ratings

AM Best, Fitch Ratings (Fitch), Moody's Investors Service (Moody's), and Standard & Poor's Rating Services (S&P) are among the third parties that assign issuer credit ratings to Unum Group and financial strength ratings to our insurance subsidiaries. Issuer credit ratings reflect an agency's opinion of the overall financial capacity of a company to meet its senior debt obligations. Financial strength ratings are specific to each individual insurance subsidiary and reflect each rating agency's view of the overall financial strength (capital levels, earnings, growth, investments, business mix, operating performance, and market position) of the insuring entity and its ability to meet its obligations to policyholders. Both the issuer credit ratings and financial strength ratings incorporate quantitative and qualitative analyses by rating agencies and are routinely reviewed and updated on an ongoing basis.

We compete based in part on the financial strength ratings provided by rating agencies. A downgrade of our financial strength ratings can be expected to adversely affect us and could potentially, among other things, adversely affect our relationships with distributors of our products and services and retention of our sales force, negatively impact persistency and new sales, particularly large case group sales and individual sales, and generally adversely affect our ability to compete. A downgrade in the issuer credit rating assigned to Unum Group can be expected to adversely affect our cost of capital or our ability to raise additional capital.

The table below reflects the outlook as well as the issuer credit ratings for Unum Group and the financial strength ratings for each of our traditional insurance subsidiaries as of the date of this filing.

We maintain an ongoing dialogue with the four rating agencies that evaluate us in order to inform them of progress we are making regarding our strategic objectives and financial plans as well as other pertinent issues. A significant component of our

97

communications involves our annual review meeting with each of the four agencies. We hold other meetings throughout the year regarding our business, including, but not limited to, quarterly updates. There have been no changes in any of the rating agencies' outlooks or ratings during 2019 prior to the date of this filing.

Agency ratings are not directed toward the holders of our securities and are not recommendations to buy, sell, or hold our securities. Each rating is subject to revision or withdrawal at any time by the assigning rating organization, and each rating should be regarded as an independent assessment, not conditional on any other rating. Given the dynamic nature of the ratings process, changes by these or other rating agencies may or may not occur in the near-term. Based on our ongoing dialogue with the rating agencies concerning our insurance risk profile, our financial flexibility, our operating performance, and the quality of our investment portfolio, we do not expect any negative actions from any of the four rating agencies related to either Unum Group's current issuer credit ratings or the financial strength ratings of our insurance subsidiaries. However, in the event that we are unable to meet the rating agency specific guideline values to maintain our current ratings, including but not limited to maintenance of our capital management metrics at the threshold values stated and maintenance of our financial flexibility and operational consistency, we could be placed on a negative credit watch, with a potential for a downgrade to both our issuer credit ratings and our financial strength ratings.

See our annual report on Form 10-K for the year ended December 31, 2018 for further information regarding our debt and financial strength ratings and the risks associated with rating changes.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are subject to various market risk exposures including interest rate risk and foreign exchange rate risk. With respect to our exposure to market risk, see the discussion under "Investments" in Item 2 of this Form 10-Q and in Part II, Item 7A of our annual report on Form 10-K for the year ended December 31, 2018. During the first six months of 2019, there was no substantive change to our market risk or the management of this risk.

ITEM 4. CONTROLS AND PROCEDURES

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this quarterly report. We assessed those controls based on criteria established in the 2013 Internal Control - Integrated Framework from the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, these officers concluded that our disclosure controls and procedures were effective as of June 30, 2019.

There have been no changes in our internal control over financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended, during the quarter ended June 30, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(f)Notwithstanding any provision of this Agreement to the contrary, the obligation of each Lender (other than the Swingline Lender) to make Revolving Loans for the purpose of repaying any Swingline Loans pursuant to Section 2.2(d) and each such Lender’s obligation to purchase a participation in any unpaid Swingline Loans pursuant to Section 2.2(e) shall be absolute and unconditional and shall not be affected by any circumstance or event whatsoever, including, without limitation, (i) any set-off, counterclaim, recoupment, defense or other right that such Lender may have against the Swingline Lender, the Administrative Agent, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence or continuance of any Default or Event of Default, (iii)

29

11863223v8 24740.00050

the failure of the amount of such Borrowing of Revolving Loans to meet the minimum Borrowing amount specified in Section 2.2(a), or (iv) the failure of any conditions set forth in Section 3.2 or elsewhere herein to be satisfied.

2.3Disbursements; Funding Reliance; Domicile of Loans.

(a)The Borrower hereby authorizes the Administrative Agent to disburse the proceeds of each Borrowing it makes in accordance with the terms of any written instructions from any Authorized Officer of the Borrower, provided that the Administrative Agent shall not be obligated under any circumstances to forward amounts to any account not listed in an Account Designation Letter.

(b)Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent its Ratable Share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.2(b) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if any Lender has not in fact made its Ratable Share of the applicable Borrowing to the Administrative Agent, then such Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation plus any administrative, processing or similar fees customarily charged by the Administrative Agent in connection with the foregoing and (ii) in the case of a payment to be made by the Borrower, the Adjusted Base Rate. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan made on the applicable Borrowing Date and such payment shall absolve any obligation of the Borrower in respect of any demand made under this Section in respect of such Loan. Any payment by the Borrower under this Section 2.3(b) shall be without prejudice to any claim the Borrower may have against any Lender that shall have failed to make such payment to the Administrative Agent.

(c)The obligations of the Lenders hereunder to make Loans, to fund participations in Letters of Credit and Swingline Loans and to make payments pursuant to Section 10.1(c) are several and not joint. The failure of any Lender to make any such Loan, fund its participation or to make any such payment on any date shall not relieve any other Lender of its corresponding obligation, if any, hereunder to do so on such date, but no Lender shall be responsible for the failure of any other Lender to so make its Loan, fund its participation or to make any such payment required hereunder.

(d)Each Lender may, at its option, make and maintain any Loan at, to or for the account of any of its Lending Offices, provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan to or for the account of such Lender in accordance with the

30

11863223v8 24740.00050

terms of this Agreement.

2.4Evidence of Debt; Notes.

(a)Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to the applicable Lending Office of such Lender resulting from each Credit Extension made by such Lending Office of such Lender, including the amounts of principal and interest payable and paid to such Lending Office of such Lender in respect of its Loans from time to time under this Agreement.

(b)The Administrative Agent shall maintain the Register pursuant to Section 10.6(c), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount of each such Loan, the Type of each such Loan and the Interest Period applicable thereto, (ii) the date and amount of each applicable L/C Disbursement made under a Letter of Credit, (iii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder in respect of each such Loan, (iv) the amount of any Reimbursement Obligation or interest due and payable or to become due and payable from the Borrower to each Lender and the Issuing Banks and (v) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s Ratable Share thereof.

(c)The entries made in the Register and subaccounts maintained pursuant to Section 2.4(b) (and, if consistent with the entries of the Administrative Agent, the accounts maintained pursuant to Section 2.4(a)) shall be conclusive evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Administrative Agent to maintain such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay (with applicable interest) its Obligations under this Agreement.

(d)The Loans made by each Lender shall, if requested by any Lender (which request shall be made to the Administrative Agent), be evidenced by a Note, executed by the Borrower and payable to such Lender. Each Note shall be entitled to all of the benefits of this Agreement and the other Credit Documents and shall be subject to the provisions hereof and thereof.

2.5Letters of Credit.

(a)Syndicated Letters of Credit.

(i)General. Each Lender agrees, on and subject to the terms and conditions of this Agreement, to Issue Letters of Credit as Syndicated Letters of Credit for the account of the Borrower in Dollars from time to time during the Availability Period. Absent the prior written consent of each Issuing Bank, no Syndicated Letter of Credit may be Issued that would vary the several and not joint nature of the obligations of the Issuing Banks thereunder as provided in the next succeeding sentence. Each Syndicated Letter of Credit shall be Issued by all of the Issuing Banks acting through the L/C Agent, at the time of Issuance as a single multi-bank letter of credit, but the obligation of each Issuing Bank thereunder shall be several and not joint, in the amount of its Ratable Share of the Stated Amount of such

31

11863223v8 24740.00050

Syndicated Letter of Credit.

(ii)Notice of Issuance. To request the Issuance of a Syndicated Letter of Credit, the Borrower shall hand deliver (or transmit by electronic communication, if arrangements for doing so have been approved by the L/C Agent) to the L/C Agent and the Administrative Agent (which will promptly notify the Lenders) at least three Business Days in advance of the requested date of Issuance (or such shorter period as is acceptable to the L/C Agent) a notice in a form reasonably acceptable to the L/C Agent (a “Syndicated Letter of Credit Notice”) requesting the Issuance of a Syndicated Letter of Credit, or identifying the Syndicated Letter of Credit to be amended, renewed, extended or increased, as the case may be, and specifying the date of Issuance (which shall be a Business Day), the date on which such Syndicated Letter of Credit is to expire (which shall comply with Section 2.5(a)(iii)), the amount of such Syndicated Letter of Credit, the name and address of the beneficiary thereof and the terms and conditions of (and such other information as shall be necessary to prepare, amend, renew, extend or increase, as the case may be) such Syndicated Letter of Credit, it being understood and agreed that Syndicated Letters of Credit may be extended and renewed in accordance with Section 2.5(a)(iii). If requested by the L/C Agent, the Borrower shall submit a letter of credit application on the L/C Agent’s standard form (with such changes as the L/C Agent shall reasonably deem appropriate) in connection with any request for a Syndicated Letter of Credit. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application submitted by the Borrower to the L/C Agent relating to any Syndicated Letter of Credit, the terms and conditions of this Agreement shall control.

(iii)Expiration of Syndicated Letters of Credit. Each Syndicated Letter of Credit shall expire at or prior to the earlier of (i) the close of business on the date one year after the date of the Issuance of such Syndicated Letter of Credit or (ii) the Final Maturity Date; provided, however, that at the Borrower’s request a Syndicated Letter of Credit shall provide by its terms, and on terms reasonably acceptable to the L/C Agent, for renewal for successive periods of one year or less (but not beyond the Final Maturity Date) unless and until the L/C Agent shall have delivered prior written notice of nonrenewal to the beneficiary of such Syndicated Letter of Credit no later than the time specified in such Syndicated Letter of Credit (which the L/C Agent shall do only if (A) the L/C Agent has determined that it would not be permitted, or would have no obligation, at such time to Issue such Syndicated Letter of Credit in its revised form (as extended) under the terms hereof, or (B) the L/C Agent has received notice (which may be by telephone or in writing) on or before the day that is seven Business Days before the applicable non-extension notice date from the Administrative Agent that (1) the Required Lenders have elected not to permit such extension or (2) one or more of the applicable conditions under Section 3.2 (other than the delivery of a Letter of Credit Notice) is not then satisfied). The L/C Agent shall promptly provide a copy of any such notice to the Borrower.

(iv)Obligation of Lenders. The obligation of any Issuing Bank under any Syndicated Letter of Credit shall be several and not joint and shall be in an amount equal to such Issuing Bank’s Ratable Share of the aggregate Stated Amount of such Syndicated

32

11863223v8 24740.00050

Letter of Credit at the time such Syndicated Letter of Credit is Issued, and each Syndicated Letter of Credit shall expressly so provide. No increase of Commitments under Section 2.21 or assignment of Commitments under Section 2.20 or Section 10.6 shall change or affect the liability of any Issuing Bank under any outstanding Syndicated Letter of Credit until such Syndicated Letter of Credit is amended giving effect to such increase, assignment or reallocation, as the case may be. The failure of any Issuing Bank to make any L/C Disbursement in respect of any Syndicated Letter of Credit on any date shall not relieve any other Issuing Bank of its corresponding obligation, if any, hereunder to do so on such date, but no Issuing Bank shall be responsible for the failure of any other Issuing Bank to make its L/C Disbursement in respect of any Syndicated Letter of Credit.

(v)Issuance Administration. Each Syndicated Letter of Credit shall be executed and delivered by the L/C Agent in the name and on behalf of, and as attorney-in-fact for, each Issuing Bank, and the L/C Agent shall act under each Syndicated Letter of Credit, and each Syndicated Letter of Credit shall expressly provide that the L/C Agent shall act, as the agent of each such Issuing Bank to (i) execute and deliver such Syndicated Letter of Credit, (ii) receive drafts, other demands for payment and other documents presented by the beneficiary under such Syndicated Letter of Credit, (iii) determine whether such drafts, demands and documents are in compliance with the terms and conditions of such Syndicated Letter of Credit, (iv) notify such Issuing Bank and the Borrower that a valid drawing has been made and the date that the related L/C Disbursement is to be made and (v) exercise all rights held by the issuer of a letter of credit under the documents for which such Syndicated Letter of Credit shall provide credit enhancement (or designate any Person as its representative for all such purposes under such documents); provided that the L/C Agent shall have no obligation or liability for any L/C Disbursement under such Syndicated Letter of Credit (other than as an Issuing Bank), and each Syndicated Letter of Credit shall expressly so provide. Each Issuing Bank hereby irrevocably appoints and designates the L/C Agent as its attorney-in-fact, acting through any duly authorized officer, to execute and deliver in the name and on behalf of such Issuing Bank each Syndicated Letter of Credit to be Issued by such Issuing Bank hereunder and to take such other actions contemplated by this Section 2.5(a)(v). Promptly upon the request of the L/C Agent, each Issuing Bank will furnish to the L/C Agent such additional powers of attorney or other evidence as any beneficiary of any Syndicated Letter of Credit may reasonably request in order to demonstrate that the L/C Agent has the power to act as attorney-in-fact for such Issuing Bank to execute and deliver such Syndicated Letter of Credit.

(vi)Disbursement Procedures. The L/C Agent shall, within a reasonable time following its receipt thereof (and, in any event, within any specific time specified in the text of the relevant Syndicated Letter of Credit), examine all documents purporting to represent a demand for payment under any Syndicated Letter of Credit. The L/C Agent shall promptly after such examination and before such L/C Disbursement notify each applicable Issuing Bank and the Borrower of such demand for payment. With respect to any demand for payment made under a Syndicated Letter of Credit which the L/C Agent has informed the applicable Issuing Banks is valid, each such Issuing Bank will promptly make an L/C Disbursement in respect of such Syndicated Letter of Credit in accordance with the amount

33

11863223v8 24740.00050

of its liability under such Syndicated Letter of Credit and this Agreement, such L/C Disbursement to be made to the account of the L/C Agent most recently designated by it for such purpose by notice to the Issuing Banks. The L/C Agent will make such L/C Disbursement available to the beneficiary of such Syndicated Letter of Credit by promptly crediting the amounts so received, in the funds so received, to the account identified by such beneficiary in connection with such demand for such L/C Disbursement. Promptly following any L/C Disbursement by any Issuing Bank in respect of any Syndicated Letter of Credit, the L/C Agent will notify the Borrower of such L/C Disbursement.

(vii)Reimbursement. The Borrower agrees that it shall reimburse the applicable Issuing Banks in respect of L/C Disbursements made under Syndicated Letters of Credit by paying to the Administrative Agent an amount in Dollarsequal to the aggregate amount of each L/C Disbursement (the “L/C Reimbursement Amount”) no later than 2:00 p.m. on the Business Day following the L/C Disbursement Date (the “Syndicated L/C Honor Date”) with respect to such Syndicated Letter of Credit together with interest thereon payable as provided in Section 2.5(e). If the Borrower fails to reimburse the Issuing Banks the L/C Reimbursement Amount on the Syndicated L/C Honor Date, so long as the conditions set forth in Section 3.2 (other than the delivery of a Notice of Borrowing) are satisfied and subject to the amount of the Unutilized Commitments, the Borrower shall be deemed to have requested a Borrowing of Base Rate Loans to be disbursed on the Syndicated L/C Honor Date in an amount equal to the L/C Reimbursement Amount, without regard to the minimum and multiples specified in Section 2.2(a)(i) for the principal amount of Borrowings, and the L/C Disbursements of each of the Issuing Banks shall be deemed to have satisfied their obligation to fund their Ratable Share of such Borrowing.

(b)Participated Letters of Credit.

(i)General. The Fronting Bank agrees, on and subject to the terms and conditions of this Agreement and in reliance upon the agreements of the Lenders set forth in this Section 2.5(b), to Issue Letters of Credit as Participated Letters of Credit for the account of the Borrower in Dollars from time to time during the Availability Period. Each Participated Letter of Credit shall be in a form customarily used or otherwise approved by the Borrower and the Fronting Bank.

(ii)Notice of Issuance. To request the Issuance of a Participated Letter of Credit, the Borrower shall hand deliver (or transmit by electronic communication, if arrangements for doing so have been approved by the Fronting Bank and Administrative Agent) to the Fronting Bank and the Administrative Agent (which will promptly notify the Lenders)at least three Business Days in advance of the requested date of Issuance (or such shorter period as is acceptable to the Fronting Bank) a notice in a form reasonably acceptable to the Fronting Bank (a “Participated Letter of Credit Notice”) requesting the Issuance of a Participated Letter of Credit, or identifying the Participated Letter of Credit to be amended, renewed, extended or increased, as the case may be, and specifying the date of Issuance (which shall be a Business Day), the date on which such Participated Letter of Credit is to expire (which shall comply with Section 2.5(b)(iii)), the amount of such Participated Letter of Credit, the

34

11863223v8 24740.00050

name and address of the beneficiary thereof and the terms and conditions of (and such other information as shall be necessary to prepare, amend, renew, extend or increase, as the case may be) such Participated Letter of Credit, it being understood and agreed that Participated Letters of Credit may be extended and renewed in accordance with Section 2.5(b)(iii). If requested by the Fronting Bank, the Borrower shall submit a letter of credit application on the Fronting Bank’s standard form (with such changes as the Fronting Bank shall reasonably deem appropriate) in connection with any request for a Participated Letter of Credit. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application submitted by the Borrower to the Fronting Bank relating to any Participated Letter of Credit, the terms and conditions of this Agreement shall control.

(iii)Expiration of Participated Letters of Credit. Each Participated Letter of Credit shall expire at or prior to the earlier of (i) the close of business on the date one year after the date of the Issuance of such Participated Letter of Credit or (ii) the Final Maturity Date; provided, however, that at the Borrower’s request a Participated Letter of Credit shall provide by its terms, and on terms reasonably acceptable to the Fronting Bank, for renewal for successive periods of one year or less (but not beyond the Final Maturity Date) unless and until the Fronting Bank shall have delivered prior written notice of nonrenewal to the beneficiary of such Participated Letter of Credit no later than the time specified in such Participated Letter of Credit (which the Fronting Bank shall do only if (A) the Fronting Bank has determined that it would not be permitted, or would have no obligation, at such time to Issue such Participated Letter of Credit in its revised form (as extended) under the terms hereof, or (B) the Fronting Bank has received notice (which may be by telephone or in writing) on or before the day that is seven Business Days before the applicable non-extension notice date from the Administrative Agent that (1) the Required Lenders have elected not to permit such extension or (2) one or more of the applicable conditions under Section 3.2 (other than the delivery of a Letter of Credit Notice) is not then satisfied). The Fronting Bank shall promptly provide a copy of any such notice to the Borrower and the Administrative Agent.

(iv)Participations. By the Issuance of a Participated Letter of Credit by the Fronting Bank (including any Existing Letters of Credit continued and deemed Issued as Participated Letters of Credit as of the Closing Date) and without any further action on the part of the Fronting Bank or the Lenders, the Fronting Bank hereby grants to each Lender in respect of such Participated Letter of Credit, and each such Lender hereby acquires from the Fronting Bank, a participation in such Participated Letter of Credit in an amount equal to the amount of such Lender’s Ratable Share of the Stated Amount of such Participated Letter of Credit and the Borrower’s reimbursement obligations with respect thereto. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Participated Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any such Letter of Credit or the existence of a Default or Event of Default or reduction or termination of the aggregate Commitments. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the

35

11863223v8 24740.00050

Administrative Agent, for the account of the Fronting Bank, the amount of such Lender’s Ratable Share of each L/C Disbursement made by the Fronting Bank in respect of any Participated Letter of Credit promptly upon the request of the Fronting Bank at any time from the time such L/C Disbursement is made until such L/C Disbursement is reimbursed by the Borrower or at any time after any reimbursement payment is required to be disgorged or refunded to the Borrower for any reason. Such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to Section 2.5(b)(vi), the Administrative Agent shall distribute such payment to the Fronting Bank or, to the extent that any Lender has made payments pursuant to this paragraph to reimburse the Fronting Bank, then to such Lenders and the Fronting Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Fronting Bank for any L/C Disbursement made by it shall not relieve the Borrower of its obligation to reimburse such L/C Disbursement. Notwithstanding anything in this Agreement to the contrary, effective upon the increase of the Commitments pursuant to Section 2.21, each Lender’s participation in any Participated Letter of Credit outstanding on such date shall be automatically adjusted to reflect its Ratable Share after giving effect to such increase.

(v)Disbursement Procedures; Reimbursement.

(A)The Fronting Bank shall, within a reasonable time following its receipt thereof (and, in any event, within any time specified in the text of the relevant Participated Letters of Credit Issued by it), examine all documents purporting to represent a demand for payment under a Participated Letter of Credit. The Fronting Bank shall promptly after such examination notify the Administrative Agent and the Borrower of such demand for payment and whether the Fronting Bank has made or will make a L/C Disbursement thereunder.

(B)The Borrower agrees that it shall reimburse the Fronting Bank in respect of any L/C Disbursement made under the Borrower’s Participated Letter of Credit by paying to the Administrative Agent an amount in Dollars equal to the amount of such L/C Disbursement no later than 2:00 p.m. on the Business Day following the L/C Disbursement Date (the “Participated L/C Honor Date”) with respect to such Participated Letter of Credit together with interest thereon payable as provided in Section 2.5(e). If the Borrower fails to so reimburse the Lenders by such time, the Administrative Agent shall promptly notify each Lender of the amount of the L/C Reimbursement Amount, and the amount of such Lender’s Ratable Share thereof. In such event, the Borrower shall be deemed to have requested a Borrowing of Base Rate Loans to be disbursed on the Participated L/C Honor Date in an amount equal to the L/C Reimbursement Amount, without regard to the minimum and multiples specified in Section 2.2(a)(i) for the principal amount of Borrowings, but subject to the amount of the Unutilized Commitments, and subject to the conditions set forth in Section 3.2 (other than the delivery of a Notice of Borrowing), and each Lender shall fund its Ratable Share of such Borrowing as set forth in Section 2.2(b). If the Borrower is unable to request a Borrowing of Base Rate Loans because it

36

11863223v8 24740.00050

cannot satisfy each of the conditions set forth in Section 3.2 (other than the delivery of a Notice of Borrowing) or for any other reason, each Lender shall fund its L/C Advance as set forth in Section 2.5(b)(vi).

(vi)Funding of Participations. If the Borrower shall fail to reimburse the Fronting Bank for any L/C Disbursement on the Participated L/C Honor Date, the Administrative Agent shall notify each Lender of the applicable L/C Disbursement, the payment then due from the Borrower in respect thereof and the amount of such Lender’s Ratable Share thereof. Each Lender shall upon such notice make funds available to the Administrative Agent in Dollars for the account of the Fronting Bank at the Payment Office in an amount equal to the amount of its Ratable Share of the unpaid L/C Disbursement (such amount, its “L/C Advance”) not later than 2:00 p.m. on the Business Day specified in such notice by the Administrative Agent. No such making of an L/C Advance shall relieve or otherwise impair the obligation of the Borrower to reimburse the Fronting Bank for the amount of any payment made by the Fronting Bank under such Participated Letter of Credit, together with interest as provided herein. If any Lender fails to make available to the Administrative Agent for the account of the Fronting Bank any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.5(b)(vi), the Fronting Bank shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Fronting Bank at a rate per annum equal to the Federal Funds Rate from time to time in effect. A certificate of the Fronting Bank submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this Section 2.5(b)(vi) shall be conclusive absent manifest error. Until a Lender funds its L/C Advance pursuant to this Section 2.5(b)(vi) to reimburse the Fronting Bank for any L/C Disbursement made by it, interest in respect of such Lender’s L/C Advance shall be solely for the account of the Fronting Bank.

(vii)Repayment of Participations.

(A)At any time after the Fronting Bank has made a payment under any Participated Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.5(b)(vi), if the Administrative Agent receives for the account of the Fronting Bank any payment in respect of the related unpaid L/C Disbursement or interest thereon (whether directly from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Administrative Agent), the Administrative Agent will distribute to such Lender its Ratable Share thereof (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s L/C Advance was outstanding) in the same funds as those received by the Administrative Agent.

(B)If any payment received by the Administrative Agent for the account of the Fronting Bank pursuant to Section 2.5(b)(v) is required to be returned under any of the circumstances described in Section 2.14 (including pursuant to any settlement entered into by the Fronting Bank in its discretion), each Lender shall pay

37

11863223v8 24740.00050

to the Administrative Agent for the account of the Fronting Bank its Ratable Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect.

(viii)Failure to Make L/C Advances. The failure of any Lender to make the L/C Advance to be made by it on the date specified in Section 2.5(b)(vi) shall not relieve any other Lender of its obligation hereunder to make its L/C Advance on such date, but no Lender shall be responsible for the failure of any other Lender to make the L/C Advance to be made by such other Lender on such date.

(c)Conditions Precedent to the Issuance of Letters of Credit. Each Issuing Bank (and the L/C Agent, on behalf of the Issuing Banks) shall be under no obligation to Issue any Letter of Credit if:

(i)any order, judgment or decree of any Governmental Authority or arbitrator shall purport by its terms to enjoin or restrain the Issuance of such Letter of Credit or any law applicable to such Issuing Bank or any Lender or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over it shall prohibit, or request that it refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon it with respect to such Letter of Credit any restriction or reserve or capital requirement (for which such Issuing Bank or any Lender is not otherwise compensated) not in effect on the Closing Date, or any unreimbursed loss, cost or expense which was not applicable, in effect or known to it as of the Closing Date;

(ii)immediately after giving effect thereto, the Aggregate Credit Exposure would exceed the aggregate Commitments at such time;

(iii)immediately after giving effect thereto, the aggregate Letter of Credit Exposure would exceed the Letter of Credit Sublimit at such time;

(vii)the expiry date of such Letter of Credit would occur more than twelve months after the date of Issuance or last extension unless the Required Lenders have approved such

38

11863223v8 24740.00050

expiry date in writing as required pursuant to Section 10.5;

(viii)the expiry date of such Letter of Credit occurs after the Final Maturity Date, unless all of the Lenders have approved such expiry date in writing as required pursuant to Section 10.5;

(ix)such Letter of Credit is not substantially in form and substance reasonably acceptable to the L/C Agent or the Fronting Bank, as applicable;

(x)such Letter of Credit is denominated in a currency other than Dollars; or

(xi)with respect to the issuance of a Participated Letter of Credit, any Lender is at that time a Defaulting Lender, unless the Fronting Bank has entered into arrangements, including the delivery of Cash Collateral, satisfactory to the Fronting Bank (in its sole discretion) with such Lender and/or the Borrower to eliminate the Fronting Bank’s actual or potential Fronting Exposure (after giving effect to Section 2.22(a)(iii)) with respect to such Defaulting Lender as it may elect in its sole discretion.

(d)Obligations Absolute. The Reimbursement Obligations of the Borrower with respect to an L/C Disbursement under any Letter of Credit and the obligations of any Lender to reimburse the Fronting Bank with respect to any L/C Disbursement made by the Fronting Bank under any Participated Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement and any Letter of Credit Document under all circumstances, including the following circumstances:

(vii)any exchange, release or non-perfection of any collateral, or any release or amendment or waiver of or consent to or departure from any guarantee, for all or any of the Obligations of the Borrower; or

(viii)any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including, without limitation, any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower or any guarantor, other than as may be expressly set forth in this Agreement.

None of the Administrative Agent, the L/C Agent, any Issuing Bank or any Lender or any of their Related Parties shall have any liability or responsibility to the Borrower by reason of or in connection with the Issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder, or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond their control; provided that the foregoing and the other provisions of this Section 2.5(d) shall not be construed to excuse the Administrative Agent, the L/C Agent, any Issuing Bank or any Lender from liability to the Borrower to the extent of any direct damages (as opposed to consequential or exemplarydamages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the gross negligence or willful misconduct of the Administrative Agent, the L/C Agent, such Issuing Bank or such Lender, as determined by a court of competent jurisdiction by final and nonappealable judgment, when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof.

(e)Interest. Unless the Borrower reimburses each L/C Disbursement made in respect of Letters of Credit issued for its account in full on the date such L/C Disbursement is made, the unpaid amount of the Reimbursement Obligation thereof shall bear interest from the date of each L/C Disbursement until such amount shall be paid in full at the rate per annum then applicable to Base Rate Loans (plus an additional 2% per annum, payable on demand, if not reimbursed by the third Business Day after the date of such L/C Disbursement). The Administrative Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Administrative Agent for purposes of this Section.

(f)Collateralization of Letters of Credit.

(i)If (i) as of the Commitment Termination Date, any Letter of Credit may for any reason remain outstanding, (ii) at any time, the Aggregate Credit Exposure shall exceed

40

11863223v8 24740.00050

the aggregate Commitments (after giving effect to any concurrent termination or reduction thereof) pursuant to Section 2.7(b) or (iii) any Event of Default occurs and is continuing and the Administrative Agent requires the Borrower to Cash Collateralize the aggregate Letter of Credit Exposure pursuant to Section 8.2(c), the Borrower shall deliver to the Administrative Agent as Cash Collateral an amount in cash equal to 103% of the aggregate Stated Amount of all Letters of Credit of the Borrower outstanding at such time (whether or not any beneficiary under any Letter of Credit shall have drawn or be entitled at such time to draw thereunder) or, in the case of clause (ii) above, an amount in cash equal to such excess. The Administrative Agent shall deposit such cash in a special collateral account of the Borrower pursuant to arrangements satisfactory to the Administrative Agent (such account, the “Cash Collateral Account”) for the benefit of the Administrative Agent, the Issuing Banks and the Lenders.

(ii)The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Banks and the Lenders, a Lien upon and security interest in its Cash Collateral Account and all amounts held therein from time to time as security for the Letter of Credit Exposure of the Borrower, and for application to its aggregate Reimbursement Obligations as and when the same shall arise. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account for the benefit of the Issuing Banks and the Lenders, and the Borrower shall have no interest therein except as set forth in clause (iii) of this Section 2.5(f). Other than any interest on the investment of such amounts in Cash Equivalents, which investments shall be made at the direction of the Borrower (unless a Default or Event of Default shall have occurred and be continuing, in which case the determination as to investments shall be made at the option and in the sole discretion of the Administrative Agent), amounts in the Cash Collateral Account shall not bear interest. Interest and profits, if any, on such investments shall accumulate in the Cash Collateral Account.

(iii)In the event of a drawing, and subsequent payment by any Issuing Bank, under any Letter of Credit at any time during which any amounts are held in the applicable Cash Collateral Account, the Administrative Agent will deliver to such Issuing Bank an amount equal to the Reimbursement Obligation created as a result of such payment (or, if the amounts so held are less than such Reimbursement Obligation, all of such amounts) to reimburse such Issuing Bank therefor. Any amounts remaining in any Cash Collateral Account (including interest and profits) after the expiration of the Letters of Credit of the Borrower and reimbursement in full of the Issuing Banks for all of their respective obligations thereunder shall be held by the Administrative Agent, for the benefit of the Borrower, to be applied against the Obligations of the Borrower in such order and manner as the Administrative Agent may direct. If the Borrower is required to provide Cash Collateral pursuant to Section2.7(b), such amount (including interest and profits), to the extent not applied as aforesaid, shall be returned to the Borrower, provided that after giving effect to such return (i) the Aggregate Credit Exposure would not exceed the aggregate Commitments at such time and (ii) no Default or Event of Default shall have occurred and be continuing at such time. If the Borrower is required to provide Cash Collateral as a result of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the

41

11863223v8 24740.00050

Borrower within three Business Days after all Events of Default have been cured or waived.

(g)Use of Letters of Credit. The Letters of Credit shall be available and the Borrower agrees that any Letters of Credit shall be used to support obligations of the Borrower or any Subsidiary under any Primary Policies or Reinsurance Agreements underwritten by such Subsidiary, the obligations of any Subsidiary as a reinsurer under any Reinsurance Agreement with respect to credit for reinsurance, and for its general corporate purposes.

(h)Existing Letters of Credit. The Borrower, the Fronting Bank and the Lenders agree that, as of the Closing Date, each Existing Letter of Credit issued for the account of the Borrower and outstanding on the Closing Date will continue and be deemed Issued under this Agreement for the account of the Borrower as a Participated Letter of Credit. There are no Syndicated Letters of Credit outstanding under the Existing Credit Agreement as of the Closing Date.

2.6Termination and Reduction of Commitments and Swingline Commitment.

(a)The aggregate Commitments shall be automatically and permanently terminated on the Commitment Termination Date. The Swingline Commitment shall be automatically and permanently terminated on the Commitment Termination Date.

(b)At any time and from time to time after the date hereof, upon not less than three Business Days’ prior written notice to the Administrative Agent (and in the case of a termination or reduction of the Unutilized Swingline Commitment, the Swingline Lender), the Borrower may terminate in whole or reduce in part the aggregate Unutilized Commitments or the Unutilized Swingline Commitment; provided that any such partial reduction shall be in an aggregate amount of not less than $5,000,000 ($500,000 in the case of the Unutilized Swingline Commitment) or, if greater, an integral multiple of $1,000,000 in excess thereof ($100,000 in the case of the Unutilized Swingline Commitment), and applied ratably among the Lenders according to their respective Commitments. Any such notice delivered by the Borrower may be conditioned upon the effectiveness of other transactions, in which case such notice may be revoked or its effectiveness deferred by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. The amount of any termination or reduction made under this Section 2.6(b) may not thereafter be reinstated. Notwithstanding any provision of this Agreement to the contrary, any reduction of the Commitments pursuant to this Section 2.6 that has the effect of reducing the aggregate Commitments to an amount less than the amount of the Swingline Commitment, the Letter of Credit Sublimit and/or the Participated Letter of Credit Sublimit at such time shall result in an automatic corresponding reduction of the Swingline Commitment, the Letter of Credit Sublimit and/or the Participated Letter of Credit Sublimit, as the case may be, to the amount of the aggregate Commitments (as so reduced), without any further action on the part of the Borrower, the Issuing Banks, the Swingline Lender or any other Lender.

(c)All fees accrued in respect of the Unutilized Commitments until the effective date of any termination thereof shall be paid on the effective date of such termination.

42

11863223v8 24740.00050

2.7Mandatory Payments and Prepayments.

(a)Except to the extent due or paid sooner pursuant to the provisions of this Agreement, the Borrower shall repay to the Lenders the aggregate outstanding principal of the Revolving Loans on the Commitment Termination Date. The aggregate outstanding principal of each Swingline Loan shall be due and payable in full on the earlier of (i) the date 10 Business Days after such Swingline Loan is made and (ii) the Commitment Termination Date.

(b)In the event that, at any time, the Aggregate Credit Exposure (excluding the aggregate amount of any Swingline Loans to be repaid with proceeds of Revolving Loans made on the date of determination) shall exceed the aggregate Commitments at such time (after giving effect to any concurrent termination or reduction thereof), the Borrower will immediately upon notice from the Administrative Agent prepay (i) the outstanding principal amount of the Swingline Loans and, to the extent of any excess remaining after prepayment in full of outstanding Swingline Loans and (ii) the outstanding principal amount of the Revolving Loans in the amount of such excess. To the extent such excess amount is greater than the aggregate principal amount of Loans outstanding immediately prior to the application of such prepayment, the amount so prepaid shall be retained by the Administrative Agent and held in the Cash Collateral Account as cover for the aggregate Letter of Credit Exposure, as more particularly described in Section 2.5(f), and thereupon such cash shall be deemed to reduce the aggregate Letter of Credit Exposure by an equivalent amount. Each payment or prepayment pursuant to the provisions of this Section 2.7 shall be applied ratably among the Lenders holding the Loans being prepaid, in proportion to the principal amount held by each. Each payment or prepayment of a LIBOR Loan made pursuant to the provisions of this Section on a day other than the last day of the Interest Period applicable thereto shall be made together with all amounts required under Section 2.19 to be paid as a consequence thereof.

2.8Voluntary Prepayments.

(a)At any time and from time to time, the Borrower shall have the right to prepay the Loans, in whole or in part, together with accrued interest to the date of prepayment, without premium or penalty (except as provided in clause (iii) below), upon written notice given to the Administrative Agent not later than 11:00 a.m. three Business Days prior to each intended prepayment of LIBOR Loans and one Business Day prior to each intended prepayment of Base Rate Loans (other than Swingline Loans, which may be prepaid on a same-day basis), provided that (i) each partial prepayment of LIBOR Loans shall be in an aggregate principal amount of not less than $5,000,000 or, if greater, an integral multiple of $1,000,000 in excess thereof, and each partial prepayment of Base Rate Loans shall be in an aggregate principal amount of not less than $3,000,000 or, if greater, an integral multiple of $1,000,000 in excess thereof ($100,000 and $100,000, respectively, in the case of Swingline Loans), (ii) no partial prepayment of LIBOR Loans made pursuant to any single Borrowing shall reduce the aggregate outstanding principal amount of the remaining LIBOR Loans under such Borrowing to less than $5,000,000 or to any greater amount not an integral multiple of $1,000,000 in excess thereof, and (iii) unless made together with all amounts required under Section 2.19 to be paid as a consequence of such prepayment, a prepayment of a LIBOR Loan may be made only on the last day of the Interest Period applicable thereto. Each such notice shall specify the proposed date of such prepayment and the aggregate principal amount and Type of the Loans

43

11863223v8 24740.00050

to be prepaid (and, in the case of LIBOR Loans, the Interest Period of such Borrowing pursuant to which made), and shall be irrevocable and shall bind the Borrower to make such prepayment on the terms specified therein, subject to any condition specified in such notice. Any such notice delivered by the Borrower may be conditioned upon the effectiveness of other transactions, in which case such notice may be revoked or its effectiveness deferred by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Revolving Loans and Swingline Loans prepaid pursuant to this Section 2.8(a) may be reborrowed, subject to the terms and conditions of this Agreement. In the event the Administrative Agent receives a notice of prepayment under this Section, the Administrative Agent will give prompt notice thereof to the Lenders; provided that if such notice has also been furnished to the Lenders, the Administrative Agent shall have no obligation to notify the Lenders with respect thereto.

(b)Each prepayment of the Loans made pursuant to Section 2.8(a) shall be applied ratably among the Lenders holding the Loans being prepaid, in proportion to the principal amount held by each.

2.9Interest.

(a)Subject to Section 2.9(b), each Loan shall bear interest on the outstanding principal amount thereof from the date of Borrowing thereof until such principal amount shall be paid in full, (i) at the Adjusted Base Rate, as in effect from time to time during such periods as such Loan is a Base Rate Loan, (ii) at the Adjusted LIBOR Rate, as in effect from time to time during such periods as such Loan is a LIBOR Loan and (iii) at the Adjusted Base Rate, as in effect from time to time during such periods as such Loan is a Swingline Loan.

(b)Upon the occurrence and during the continuance of any Default or Event of Default under Section 8.1(a), Section 8.1(f) or Section 8.1(g) and (at the election of the Required Lenders) upon the occurrence and during the continuance of any other Event of Default, all outstanding principal amounts of the Loans, all Reimbursement Obligations (to the extent not already bearing an additional 2% per annum pursuant to Section 2.5(e)) and, to the greatest extent permitted by law, all interest accrued on the Loans and all other accrued and outstanding fees and other amounts hereunder, shall bear interest at a rate per annum equal to the interest rate applicable from time to time thereafter to such Loans (whether the Adjusted Base Rate or the Adjusted LIBOR Rate) plus 2% (or, in the case of interest, fees and other amounts for which no rate is provided hereunder, at the Adjusted Base Rate plus 2%), and, in each case, such default interest shall be payable on demand. To the greatest extent permitted by law, interest shall continue to accrue after the filing by or against the Borrower of any petition seeking any relief under any Debtor Relief Law.

(c)Accrued (and theretofore unpaid) interest in respect of any Loan shall be payable as follows:

(i)in respect of each Base Rate Loan and Swingline Loan, in arrears on the last Business Day of each calendar quarter, beginning with the first such day to occur after the Closing Date;

44

11863223v8 24740.00050

(ii)in respect of each LIBOR Loan, in arrears (y) on the last Business Day of the Interest Period applicable thereto (subject to the provisions of Section 2.11(iv)) and (z) in addition, in the case of a LIBOR Loan with an Interest Period having a duration of six months, on each date on which interest would have been payable under clause (y) above had successive Interest Periods of three months’ duration been applicable to such LIBOR Loan;

(iii)upon any payment of any Loan pursuant to Section 2.7 or Section 2.8 (other than the prepayment of a Base Rate Loan prior to the Commitment Termination Date), to the extent accrued on the amount being paid or prepaid; and

(iv)in respect of any Loan, at maturity (whether pursuant to acceleration or otherwise) and, after maturity, on demand.

(d)Nothing contained in this Agreement or in any other Credit Document shall be deemed to establish or require the payment of interest to any Lender at a rate in excess of the maximum rate permitted by applicable law. If the amount of interest payable for the account of any Lender on any interest payment date would exceed the maximum amount permitted by applicable law to be charged by such Lender, the amount of interest payable for its account on such interest payment date shall be automatically reduced to such maximum permissible amount. In the event of any such reduction affecting any Lender, if from time to time thereafter the amount of interest payable for the account of such Lender on any interest payment date would be less than the maximum amount permitted by applicable law to be charged by such Lender, then the amount of interest payable for its account on such subsequent interest payment date shall be automatically increased to such maximum permissible amount, provided that at no time shall the aggregate amount by which interest paid for the account of any Lender has been increased pursuant to this sentence exceed the aggregate amount by which interest paid for its account has theretofore been reduced pursuant to the previous sentence.

(e)The Administrative Agent shall promptly notify the Borrower and the Lenders upon determining the interest rate for each Borrowing of LIBOR Loans after its receipt of the relevant Notice of Borrowing or Notice of Conversion/Continuation, and upon each change in the Base Rate; provided, however, that the failure of the Administrative Agent to provide the Borrower or the Lenders with any such notice shall neither affect any obligations of the Borrower or the Lenders hereunder nor result in any liability on the part of the Administrative Agent to the Borrower or any Lender. Each such determination (including each determination of the Reserve Requirement) shall, absent manifest error, be conclusive and binding on all parties hereto.

2.10Fees. The Borrower agrees to pay:

(a)To the Arrangers, the Fronting Bank and the Administrative Agent, for their own respective accounts, the fees required under the Fee Letters to be paid to them and the Lenders in the amounts and at the times as required by the terms thereof;

(b)To the Administrative Agent, for the account of each Lender, a commitment fee (the “Commitment Fee”), which shall accrue at a per annum rate equal to the Applicable Percentage in

45

11863223v8 24740.00050

effect for such fee from time to time during each calendar quarter (or portion thereof) on such Lender’s Unutilized Commitment (excluding clause (ii) of the definition thereof for purposes of this Section 2.10(b) only), during the period from and including the date hereof to but excluding the Commitment Termination Date; provided, however, that no Commitment Fee shall accrue on the Unutilized Commitments of a Defaulting Lender during any period that such Lender shall be a Defaulting Lender. Accrued Commitment Fees shall be payable in arrears (i) on the last Business Day of each calendar quarter, beginning with the first such day to occur after the date hereof and (ii) on the Commitment Termination Date. All Commitment Fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day);

(c)To the Administrative Agent, for the account of each Lender, a letter of credit fee (the “Letter of Credit Fee”) for each calendar quarter (or portion thereof) in respect of all Letters of Credit outstanding during such quarter, at a per annum rate equal to the Applicable Percentage in effect for such fee from time to time during such quarter on such Lender’s Ratable Share of the average daily aggregate Stated Amount of Letters of Credit outstanding during such quarter; provided, however, that any Letter of Credit Fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which such Defaulting Lender has not provided Cash Collateral satisfactory to the Fronting Bank pursuant to Section 2.5(c)(xi) shall be payable, to the maximum extent permitted by applicable Law, to the other Lenders in accordance with the upward adjustments in their respective Ratable Shares allocable to such Letter of Credit pursuant to Section 2.22(a)(iii), with the balance of such fee, if any, payable to the Fronting Bank for its own account. The Letter of Credit Fee shall be due and payable quarterly in arrears (i) on the last Business Day of each calendar quarter, commencing with the first such date to occur after the Closing Date through the Final Maturity Date and (ii) on the Final Maturity Date;

(d)To the Administrative Agent, for its own account, the annual administrative agent’s fee described in its Fee Letter, on the terms, in the amount and at the times set forth therein; and

(e)To the Fronting Bank, for its own account, with respect to the Issuance of each Participated Letter of Credit hereunder, a fronting fee described in its Fee Letter, on the terms, in the amount and at the times set forth therein and, to the Fronting Bank and the L/C Agent, such reasonable fees and expenses as the Fronting Bank or L/C Agent customarily requires in connection with the issuance, amendment, transfer, negotiation, processing and/or administration of letters of credit.

2.11Interest Periods. Concurrently with the giving of a Notice of Borrowing or Notice of Conversion/Continuation in respect of any Borrowing comprised of Base Rate Loans to be converted into, or LIBOR Loans to be continued as, LIBOR Loans, the Borrower shall have the right to elect, pursuant to such notice, the interest period (each, an “Interest Period”) to be applicable to such LIBOR Loans, which Interest Period shall, at the option of the Borrower, be a one, two, three or six-month period; provided, however, that:

(i)all LIBOR Loans comprising a single Borrowing shall at all times have the same Interest Period;

46

11863223v8 24740.00050

(ii)the initial Interest Period for any LIBOR Loan shall commence on the date of the Borrowing of such LIBOR Loan (including the date of any continuation of, or conversion into, such LIBOR Loan, and each successive Interest Period applicable to such LIBOR Loan shall commence on the day on which the immediately preceding Interest Period applicable thereto expires;

(iii)LIBOR Loans may not be outstanding under more than four separate Interest Periods at any one time (for which purpose Interest Periods shall be deemed to be separate even if they are coterminous);

(iv)if any Interest Period otherwise would expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day unless such next succeeding Business Day falls in another calendar month, in which case such Interest Period shall expire on the immediately preceding Business Day;

(v)no Interest Period may be selected with respect to the Loans that would end after a scheduled date for repayment of principal of the Loans occurring on or after the first day of such Interest Period unless, immediately after giving effect to such selection, the aggregate principal amount of Loans that are Base Rate Loans or that have Interest Periods expiring on or before such principal repayment date equals or exceeds the principal amount required to be paid on such principal repayment date;

(vi)the Borrower may not select any Interest Period that expires after the Commitment Termination Date, with respect to Loans that are to be maintained as LIBOR Loans;

(vii)if any Interest Period begins on a day for which there is no numerically corresponding day in the calendar month during which such Interest Period would otherwise expire, such Interest Period shall expire on the last Business Day of such calendar month; and

(viii)the Borrower may not select any Interest Period (and consequently, no LIBOR Loans shall be made) if a Default or Event of Default shall have occurred and be continuing at the time of such Notice of Borrowing or Notice of Conversion/Continuation with respect to any Borrowing.

2.12Conversions and Continuations.

(a)The Borrower shall have the right, on any Business Day occurring on or after the Closing Date, to elect (i) to convert all or a portion of the outstanding principal amount of any Base Rate Loans into LIBOR Loans, or to convert any LIBOR Loans the Interest Periods for which end on the same day into Base Rate Loans, or (ii) upon the expiration of any Interest Period, to continue all or a portion of the outstanding principal amount of any LIBOR Loans the Interest Periods for which end on the same day for an additional Interest Period, provided that (w) any such conversion of LIBOR Loans of the same Borrowing into Base Rate Loans shall involve an aggregate principal amount of not less than $3,000,000 or, if greater, an integral multiple of $1,000,000 in excess thereof;

47

11863223v8 24740.00050

any such conversion of Base Rate Loans of the same Borrowing into, or continuation of, LIBOR Loans shall involve an aggregate principal amount of not less than $5,000,000 or, if greater, an integral multiple of $1,000,000 in excess thereof; and no partial conversion of LIBOR Loans of the same Borrowing shall reduce the outstanding principal amount of LIBOR Loans to less than $5,000,000 or to any greater amount not an integral multiple of $1,000,000 in excess thereof, (x) if a LIBOR Loan is converted into a Base Rate Loan on any day other than the last day of the Interest Period applicable thereto, the Borrower will pay, upon such conversion, all amounts required under Section 2.19 to be paid as a consequence thereof, (y) no such conversion or continuation shall be permitted with regard to any Swingline Loans and (z) no conversion of Base Rate Loans into LIBOR Loans or continuation of LIBOR Loans shall be permitted during the continuance of a Default or Event of Default.

(b)The Borrower shall make each such election by giving the Administrative Agent written notice not later than 11:00 a.m. three Business Days prior to the intended effective date of any conversion of Base Rate Loans into, or continuation of, LIBOR Loans and one Business Day prior to the intended effective date of any conversion of LIBOR Loans into Base Rate Loans. Each such notice (each, a “Notice of Conversion/Continuation”) shall be irrevocable, shall be given in the form of Exhibit B-3 and shall specify (x) the date of such conversion or continuation (which shall be a Business Day), (y) in the case of a conversion into, or a continuation of, LIBOR Loans, the Interest Period to be applicable thereto, and (z) the aggregate amount and Type of the Loans being converted or continued. Upon the receipt of a Notice of Conversion/Continuation, the Administrative Agent will promptly notify each Lender of the proposed conversion or continuation. In the event that the Borrower shall fail to deliver a Notice of Conversion/Continuation as provided herein with respect to any outstanding LIBOR Loans, such LIBOR Loans shall automatically be converted to Base Rate Loans upon the expiration of the then-current Interest Period applicable thereto (unless repaid pursuant to the terms hereof). In the event the Borrower shall have failed to select in a Notice of Conversion/Continuation the duration of the Interest Period to be applicable to any conversion into, or continuation of, LIBOR Loans, then the Borrower shall be deemed to have selected an Interest Period with a duration of one month.

2.13Method of Payments; Computations; Apportionment of Payments.

(a)All payments by the Borrower hereunder shall be made without setoff, counterclaim or other defense, in Dollars and in immediately available funds to the Administrative Agent, for the account of the Lenders entitled to such payment or the Swingline Lender, as the case may be (except as otherwise expressly provided herein as to payments required to be made directly to the Administrative Agent, the Issuing Banks or the Lenders), at the Payment Office prior to 2:00 p.m. on the date payment is due. Any payment made as required hereinabove, but after 2:00 p.m. shall be deemed to have been made on the next succeeding Business Day. If any payment falls due on a day that is not a Business Day, then such due date shall be extended to the next succeeding Business Day (except that in the case of LIBOR Loans to which the provisions of Section 2.11(iv) are applicable, such due date shall be the immediately preceding Business Day), and such extension of time shall then be included in the computation of payment of interest, fees or other applicable amounts.

48

11863223v8 24740.00050

(b)The Administrative Agent will distribute to the Lenders like amounts relating to payments made to the Administrative Agent for the account of the Lenders as follows: (i) if the payment is received by 12:00 noon in immediately available funds, the Administrative Agent will make available to each relevant Lender on the same date, by wire transfer of immediately available funds, such Lender’s Ratable Share of such payment, and (ii) if such payment is received after 12:00 noon or in other than immediately available funds, the Administrative Agent will make available to each such Lender its Ratable Share of such payment by wire transfer of immediately available funds on the next succeeding Business Day (or in the case of uncollected funds, as soon as practicable after collected). Notwithstanding the foregoing or any contrary provision hereof, if any Lender shall fail to make any payment required to be made by it hereunder to the Administrative Agent, the Fronting Bank or the Swingline Lender, then the Administrative Agent may, in its discretion, apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations to the Administrative Agent, the Fronting Bank or the Swingline Lender, as the case may be, until all such unsatisfied obligations are fully paid.If the Administrative Agent shall not have made a required distribution to the appropriate Lenders as required hereinabove after receiving a payment for the account of such Lenders, the Administrative Agent will pay to each such Lender, on demand, its Ratable Share of such payment with interest thereon at the Federal Funds Rate for each day from the date such amount was required to be disbursed by the Administrative Agent until the date repaid to such Lender. The Administrative Agent will distribute to the Issuing Banks and Swingline Lender like amounts relating to payments made to the Administrative Agent for the account of the Issuing Banks and Swingline Lender in the same manner, and subject to the same terms and conditions, as set forth hereinabove with respect to distributions of amounts to the Lenders.

(c)Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the relevant Lenders or the Issuing Banks hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the relevant Lenders, the Issuing Banks or the Swingline Lender, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the relevant Lenders, the Issuing Banks or the Swingline Lender, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the Issuing Banks, with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(d)All computations of interest and fees hereunder (including computations of the Reserve Requirement) shall be made on the basis of a year consisting of (i) in the case of interest on Base Rate Loans based on the prime commercial lending rate of the Administrative Agent, 365/366 days, as the case may be, or (ii) in all other instances, 360 days; and in each case under (i) and (ii) above, with regard to the actual number of days (including the first day, but excluding the last day) elapsed.

49

11863223v8 24740.00050

(e)Notwithstanding any other provision of this Agreement or any other Credit Document to the contrary, all amounts collected or received by the Administrative Agent or any Lender after acceleration of the Loans pursuant to Section 8.2 shall be applied by the Administrative Agent as follows:

(i)first, to the payment of all reasonable out-of-pocket costs and expenses (including, without limitation, reasonable attorneys’ and consultants’ fees irrespective of whether such fees are allowed as a claim after the occurrence of a Bankruptcy Event) of the Administrative Agent in connection with enforcing the rights of the Lenders under the Credit Documents;

(ii)second, to the payment of any fees owed to the Administrative Agent and the Fronting Bank hereunder or under any other Credit Document;

(iii)third, to the payment of all reasonable and documented out-of-pocket costs and expenses (including, without limitation, reasonable attorneys’ and consultants’ fees irrespective of whether such fees are allowed as a claim after the occurrence of a Bankruptcy Event) of each of the Lenders, the Swingline Lender, the Issuing Banks and the L/C Agent in connection with enforcing its rights under the Credit Documents or otherwise with respect to the Obligations owing to such Lender;

(iv)fourth, to the payment of all of the Obligations consisting of accrued fees and interest (including, without limitation, fees incurred and interest accruing at the then applicable rate after the occurrence of a Bankruptcy Event irrespective of whether a claim for such fees incurred and interest accruing is allowed in such proceeding);

(v)fifth, to the payment of the outstanding principal amount of the Obligations (including the payment of any outstanding Reimbursement Obligations);

(vi)sixth, to Cash Collateralize Letter of Credit Exposure and to the payment of all other Obligations and other obligations that shall have become due and payable under the Credit Documents or otherwise and not repaid; and

(vii)seventh, to the payment of the surplus (if any) to the Borrower or whomever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (x) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category, (y) all amounts shall be apportioned ratably among the Lenders, the Swingline Lender and the Issuing Banks in proportion to the amounts of such principal, interest, fees or other Obligations owed to them respectively pursuant to clauses (iii) through (vii) above, and (z) to the extent that any amounts available for distribution pursuant to clause (v) above are attributable to the issued but undrawn amount of outstanding Letters of Credit, such amounts shall be held by the Administrative Agent to Cash Collateralize Letter of Credit Exposure pursuant to Section 2.5(f).

2.14Recovery of Payments.

(a)The Borrower agrees that to the extent the Borrower makes a payment or payments to or for the account of the Administrative Agent, the Swingline Lender, any Lender or any Issuing Bank, which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other party under any Debtor Relief Law, common law or equitable cause (whether as a result of any demand, settlement, litigation or otherwise), then, to the extent of such payment or repayment, the Obligation intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been received.

(b)If any amounts distributed by the Administrative Agent to any Lender or any Issuing Bank are subsequently returned or repaid by the Administrative Agent to the Borrower, its representative or successor in interest, or any other Person, whether by court order, by settlement approved by such Lender or such Issuing Bank, or pursuant to applicable Requirements of Law, such Lender or such Issuing Bank will, promptly upon receipt of notice thereof from the Administrative Agent, pay the Administrative Agent such amount. If any such amounts are recovered by the Administrative Agent from the Borrower, its representative or successor in interest or such other Person, the Administrative Agent will redistribute such amounts to the Lenders or the Issuing Banks on the same basis as such amounts were originally distributed.

2.15Use of Proceeds. The proceeds of the Loans shall be used to provide for the working capital and general corporate requirements of the Borrower and its Subsidiaries not in contravention of any Requirement of Law or any provision of this Agreement or any other Credit Document. Without limiting the generality of the foregoing, no proceeds from any Credit Extension shall be used, directly or, to the Borrower’s knowledge after due care and inquiry, indirectly, (i) in furtherance of an offer, payment, promise to pay, or authorization of the payment or giving of money, or anything else of value, to any Person in violation of any Anti-Corruption Laws, (ii) for the purpose of funding, financing or facilitating any activities, business or transaction of or with any Sanctioned Person, or in any Sanctioned Country, or (iii) in any manner that would result in the violation of any Anti-Money Laundering Laws or Sanctions applicable to any party hereto.

2.16Pro Rata Treatment.

(a)Except in the case of Swingline Loans, all fundings, continuations and conversions of Loans shall be made by the Lenders pro rata on the basis of their Ratable Share (in the case of the initial making of the Loans) or on the basis of their respective outstanding Loans (in the case of continuations and conversions of the Loans), as the case may be from time to time. All payments on account of principal of or interest on any Loans, fees or any other Obligations owing to or for the account of any one or more Lenders shall be apportioned ratably among such Lenders in proportion to the amounts of such principal, interest, fees or other Obligations owed to them respectively.

(b)If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other Obligations hereunder resulting in such Lender receiving payment of a proportion of the aggregate amount of

51

11863223v8 24740.00050

its Loans and accrued interest thereon or other such Obligations greater than its Ratable Share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other Obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other Obligations owing them, provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender) or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans, Reimbursement Obligations or Swingline Loans to any assignee or Participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this Section 2.16(b) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. If under any applicable Debtor Relief Law, any Lender receives a secured claim in lieu of a setoff to which this Section 2.16(b) applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section 2.16(b) to share in the benefits of any recovery on such secured claim.

2.17Increased Costs; Change in Circumstances; Illegality.

(a)If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except the Reserve Requirement reflected in the LIBOR Rate) or any Issuing Bank;

(ii)subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (ii) through (iv) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii)impose on any Lender or any Issuing Bank or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Loan or of maintaining its obligation to make or participate in any such Loan, or to increase the cost to such Lender, such

52

11863223v8 24740.00050

Issuing Bank or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, such Issuing Bank or other Recipient hereunder (whether of principal, interest or any other amount), then, upon request of such Lender, such Issuing Bank or other Recipient, the Borrower will pay to such Lender, such Issuing Bank or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, such Issuing Bank or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

(b)If any Lender or any Issuing Bank determines that any Change in Law affecting such Lender or such Issuing Bank or any Lending Office of such Lender or such Lender’s or such Issuing Bank’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s or such Issuing Bank’s capital or on the capital of such Lender’s or such Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company for any such reduction suffered.

(c)A certificate of a Lender or an Issuing Bank setting forth the calculation in reasonable detail of the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as specified in Section 2.17(a) or Section 2.17(b) and delivered to the Borrower shall be conclusive absent manifest error. The Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

(d)Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or such Issuing Bank pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than six months prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof).

(e)Unless and until a Replacement Rate is implemented in accordance with clause (f) below, if on or prior to the first day of any Interest Period, (x) the Administrative Agent shall have determined (which determination shall be conclusive absent manifest error) that Dollar deposits are

53

11863223v8 24740.00050

not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Loan, (y) the Administrative Agent shall have determined that adequate and reasonable means do not exist for ascertaining the applicable LIBOR Rate for such Interest Period or (z) the Administrative Agent shall have received written notice from the Required Lenders of their determination that the rate of interest referred to in the definition of “LIBOR Rate” upon the basis of which the Adjusted LIBOR Rate for LIBOR Loans for such Interest Period is to be determined will not adequately and fairly reflect the cost to such Lenders of making or maintaining LIBOR Loans during such Interest Period, the Administrative Agent will promptly so notify the Borrower and the Lenders. Upon such notice, (i) all then-outstanding LIBOR Loans shall automatically, on the expiration date of the respective Interest Periods applicable thereto (unless then repaid in full), be converted into Base Rate Loans, (ii) the obligation of the Lenders to make, to convert Base Rate Loans into, or to continue, LIBOR Loans shall be suspended (including pursuant to the Borrowing to which such Interest Period applies) and (iii) any Notice of Borrowing or Notice of Conversion/Continuation given at any time thereafter with respect to LIBOR Loans shall be deemed to be a request for Base Rate Loans, in each case until the Administrative Agent or the Required Lenders, as the case may be, shall have determined that the circumstances giving rise to such suspension no longer exist (and the Required Lenders, if making such determination, shall have so notified the Administrative Agent), and the Administrative Agent shall have so notified the Borrower and the Lenders.

(f)Notwithstanding anything to the contrary in Section 2.17(e) above, if the Administrative Agent determines (which determination shall be conclusive absent manifest error) that (i) the circumstances described in Section 2.17(e)(x) or (e)(y) have arisen and that such circumstances are unlikely to be temporary, (ii) the LIBOR Rate specified herein is no longer a widely recognized benchmark rate for newly originated loans in the U.S. syndicated loan market or (iii) the applicable supervisor or administrator (if any) of the LIBOR Rate or any Governmental Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the LIBOR Rate shall no longer be used (or required to be published) for determining interest rates for loans in the U.S. syndicated loan market, then the Administrative Agent and the Borrower may amend this Agreement to replace the LIBOR Rate with a replacement interest rate, giving due consideration to any evolving or then existing convention for similar Dollar denominated syndicated credit facilities for such alternative benchmarks (the “Replacement Rate”), in which case, the Replacement Rate shall, subject to the next two sentences, replace the LIBOR Rate for all purposes under this Agreement unless and until (A) an event described in Section 2.17(e)(x), (e)(y), (f)(i), (f)(ii) or (f)(iii) occurs with respect to the Replacement Rate or (B) the Required Lenders (directly, or through the Administrative Agent) notify the Borrower that the Replacement Rate does not adequately and fairly reflect the cost to the Lenders of funding the Loans bearing interest at the Replacement Rate. In connection with the establishment and application of the Replacement Rate, this Agreement shall be amended solely with the consent of the Administrative Agent and the Borrower, as may be necessary or appropriate to effect the provisions of this Section 2.17(f). Notwithstanding anything to the contrary in this Agreement (including, without limitation, Section 10.5), such amendment shall become effective without any further action or consent of any other party to this Agreement so long as the Administrative Agent shall not have received, within five (5) Business Days of the delivery of such amendment to the Lenders, written notices from such Lenders that in the aggregate constitute Required Lenders, with each such notice stating that such

54

11863223v8 24740.00050

Lender objects to such amendment. The Replacement Rate shall be applied in a manner consistent with market practice; provided that, in each case, to the extent such market practice is not administratively feasible for the Administrative Agent, such Replacement Rate shall be applied as otherwise reasonably determined by the Administrative Agent in a manner consistent with other credit facilities of the Administrative Agent with similarly situated borrowers (it being understood that any such modification shall not require the consent of, or consultation with, any of the Lenders). After any of the circumstances described in Section2.17(f)(i), (f)(ii) or (f)(iii) have occurred, the Administrative Agent will promptly so notify the Borrower and each Lender. Thereafter, until a Replacement Rate has been determined, (x) the obligation of the Lenders to make or maintain LIBOR Loans shall be suspended, and (y) the LIBOR Rate component shall no longer be utilized in determining the Base Rate. Upon receipt of such notice, the Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of LIBOR Rate Loans or, failing that, will be deemed to have converted such request into a request for a Borrowing of Base Rate Loans (subject to the foregoing clause (y)) in the amount specified therein.

(g)Notwithstanding any other provision in this Agreement, if, at any time after the date hereof and from time to time, any Lender determines in good faith that any Change in Law has or would have the effect of making it unlawful for such Lender or its applicable Lending Office to make or to continue to make or maintain LIBOR Loans, such Lender will forthwith so notify the Administrative Agent and the Borrower. Upon such notice, (i) each of such Lender’s then outstanding LIBOR Loans shall automatically, on the expiration date of the respective Interest Period applicable thereto (or, to the extent any such LIBOR Loan may not lawfully be maintained as a LIBOR Loan until such expiration date, upon such notice) and to the extent not sooner prepaid, be converted into a Base Rate Loan, (ii) the obligation of such Lender to make, to convert Base Rate Loans into, or to continue, LIBOR Loans shall be suspended (including pursuant to any Borrowing for which the Administrative Agent has received a Notice of Borrowing but for which the Borrowing Date has not arrived), and (iii) any Notice of Borrowing or Notice of Conversion/Continuation given at any time thereafter with respect to LIBOR Loans shall, as to such Lender, be deemed to be a request for a Base Rate Loan, in each case until such Lender shall have determined that the circumstances giving rise to such suspension no longer exist and shall have so notified the Administrative Agent, and the Administrative Agent shall have so notified the Borrower.

(h)Similar Treatment. Notwithstanding the foregoing Sections 2.17(a) and 2.17(b), no Lender, Issuing Bank or Recipient shall impose any costs specified therein or make any request for compensation pursuant thereto (or be entitled to any such additional costs) unless such Lender, Issuing Bank or Recipient is then generally imposing such cost upon or requesting such compensation from borrowers in connection with similar credit facilities containing similar provisions and at the time of such request certifies to the Borrower to the effect of the foregoing; provided such Lender, Issuing Bank or Recipient shall not be required to disclose any of its records or any other information that it deems confidential.

2.18Taxes.

(a)For purposes of this Section 2.18, the term “Lender” includes each Issuing Bank.

(b)Any and all payments by or on account of any obligation of the Borrower under any

55

11863223v8 24740.00050

Credit Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section 2.18) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c)The Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d)The Borrower shall indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section 2.18) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e)Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 10.6(e) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Credit Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Credit Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this Section 2.18(e).

(f)As soon as practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant to this Section 2.18, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

56

11863223v8 24740.00050

(g)Status of Lenders.

(i)Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Credit Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 2.18(g)(ii)(A), 2.18(g)(ii)(B) and 2.18(g)(ii)(D)) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii)Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person:

(A)any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(1)in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Credit Document, executed copies of IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Credit Document, executed copies of IRS Form W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

57

11863223v8 24740.00050

(2)executed copies of IRS Form W-8ECI;

(3)in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit G-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN-E; or

(4)to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W‑8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-4 on behalf of each such direct and indirect partner;

(C)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D)if a payment made to a Lender under any Credit Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and

58

11863223v8 24740.00050

withhold from such payment. Solely for purposes of this Section 2.18(g)(ii)(D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

(h)If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.18 (including by the payment of additional amounts pursuant to this Section 2.18), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 2.18 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 2.18(h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 2.18(h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 2.18(h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This Section 2.18(h) shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i)Each party’s obligations under this Section 2.18 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Credit Document.

2.19Compensation. The Borrower will compensate each Lender upon demand for all losses (other than loss of Applicable Percentage), expenses and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund or maintain LIBOR Loans) that such Lender may incur or sustain (i) if for any reason (other than a default by such Lender) the initial borrowing of a LIBOR Loan or continuation of, or conversion into a LIBOR Loan does not occur on a date specified therefor in a Notice of Borrowing or a Notice of Conversion/Continuation, (ii) if any repayment, prepayment or conversion of any LIBOR Loan occurs on a date other than the last day of an Interest Period applicable thereto (including as a consequence of any assignment made pursuant to Section 2.20(a) or any acceleration of the maturity of the Loans pursuant to Section 8.2), (iii) if any prepayment of any LIBOR Loan is not made on any date specified in a notice of prepayment given by the Borrower or (iv) as a consequence of any other failure by the Borrower to make any

59

11863223v8 24740.00050

payments with respect to any LIBOR Loan when due hereunder. Calculation of all amounts payable to a Lender under this Section 2.19 shall be made as though such Lender had actually funded its relevant LIBOR Loan through the purchase of a Eurodollar deposit bearing interest at the LIBOR Rate in an amount equal to the amount of such LIBOR Loan, having a maturity comparable to the relevant Interest Period; provided, however, that each Lender may fund its LIBOR Loans in any manner it sees fit and the foregoing assumption shall be utilized only for the calculation of amounts payable under this Section 2.19. The Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing. A certificate (which shall be in reasonable detail) showing the bases for the determinations set forth in this Section 2.19 by any Lender as to any additional amounts payable pursuant to this Section 2.19 shall be submitted by such Lender to the Borrower either directly or through the Administrative Agent. Determinations set forth in any such certificate made in good faith for purposes of this Section 2.19 of any such losses, expenses or liabilities shall be conclusive absent manifest error.

2.20Replacement of Lenders; Mitigation of Costs.

(a)If any Lender requests compensation under Sections 2.17(a) or 2.17(b), or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.18, or if any Lender’s obligation to make or maintain LIBOR Loans has been suspended under Section 2.17(f) and, in each case, such Lender has declined or is unable to designate a different Lending Office in accordance with Section 2.20(b), or if any Lender is a Defaulting Lender or a Non-Consenting Lender, then the Borrower may, at is sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 10.6), all of its interests, rights (other than its existing rights to payments pursuant to Sections 2.17(a), 2.17(b) or 2.18) and obligations under this Agreement and the related Credit Documents to an Eligible Assignee that shall assume such obligations (which Eligible Assignee may be another Lender, if a Lender accepts such assignment); provided that:

(i)the Administrative Agent shall have received the assignment fee specified in Section 10.6(b)(iv);

(ii)such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, any L/C Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents (including any amounts under Section 2.19) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii)in the case of any such assignment resulting from a request for compensation under Sections 2.17(a) or 2.17(b) or payments required to be made pursuant to Section 2.18, such assignment will result in a reduction in such compensation or payments thereafter;

(iv)such assignment does not conflict with applicable Requirements of Law; and

60

11863223v8 24740.00050

(v)in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable Eligible Assignee shall have consented to the applicable amendment, waiver or consent.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

(b)If any Lender requests compensation under Sections 2.17(a) or 2.17(b), or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.18, or if any Lender gives a notice pursuant to Section 2.17(f), then such Lender shall use reasonable efforts to designate a different Lending Office for funding or booking its Loans or L/C Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Sections 2.17(a), 2.17(b) or 2.18, as the case may be, in the future, or eliminate the need for the notice pursuant to Section 2.17(f), as applicable, and (ii) in each case, would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender as it so deems in good faith. The Borrower hereby agrees to pay all reasonable out-of-pocket costs and expenses incurred by any Lender in connection with any such designation or assignment.

2.21Increase in Commitments.

(a)The Borrower shall have the right, at any time and from time to time after the Closing Date but prior to the date 30 days prior to the Commitment Termination Date by written notice to and in consultation with the Administrative Agent, to request an increase in the aggregate Commitments (each such requested increase, a “Commitment Increase”), by having one or more existing Lenders increase their respective Commitments then in effect (each, an “Increasing Lender”), by adding as a Lender with a new Commitment hereunder one or more Persons that are not already Lenders (each, an “Additional Lender”), or a combination thereof; provided that (i) any such request for a Commitment Increase shall be in a minimum amount of $25,000,000 or an integral multiple of $1,000,000 in excess thereof, (ii) immediately after giving effect to any Commitment Increase, the aggregate of all Commitment Increases effected after the Closing Date shall not exceed $200,000,000, and (iii) no existing Lender shall be obligated to increase its Commitment as a result of any request for a Commitment Increase by the Borrower unless it agrees in its sole discretion to do so.

(b)Each Additional Lender must qualify as an Eligible Assignee (the approval of which by the Administrative Agent, the Swingline Lender and the Fronting Bank shall not be unreasonably withheld or delayed) and the Borrower and each Additional Lender shall execute a Lender Joinder Agreement together with all such other documentation as the Administrative Agent and the Borrower may reasonably require, all in form and substance reasonably satisfactory to the Administrative Agent and the Borrower, to evidence the Commitment of such Additional Lender and its status as a Lender hereunder.

61

11863223v8 24740.00050

(c)If the aggregate Commitments are increased in accordance with this Section, the Administrative Agent and the Borrower shall determine the effective date (the “Commitment Increase Date,” which shall be a Business Day not less than 30 days prior to the Commitment Termination Date) and the final allocation of such increase. The Administrative Agent shall promptly notify the Borrower and the Lenders of the final allocation of such increase and the Commitment Increase Date. The Administrative Agent is hereby authorized, on behalf of the Lenders, to enter into any amendments to this Agreement and the other Credit Documents as the Administrative Agent shall reasonably deem appropriate to effect such Commitment Increase.

(d)Notwithstanding anything set forth in this Section2.21, no increase in the aggregate Commitments pursuant to this Section2.21 shall be effective unless:

(B)an instrument, duly executed by the Borrower, acknowledging and reaffirming its obligations under this Agreement and the other Credit Documents;

(C)a certificate of the secretary or an assistant secretary of the Borrower, certifying to and attaching the resolutions adopted by the board of directors (or similar governing body) of the Borrower approving or consenting to such Commitment Increase;

(ii)If there is a non-ratable increase in the aggregate Commitments, each outstanding Syndicated Letter of Credit shall have been amended giving effect to the reallocation of the Commitments or, if required, returned by each respective beneficiary to

62

11863223v8 24740.00050

the Administrative Agent and cancelled and/or exchanged for a new or amended Syndicated Letter of Credit giving effect to the reallocated Commitments; and

(iii)The conditions precedent set forth in Section 3.2 shall have been satisfied.

(e)On the Commitment Increase Date, to the extent necessary to keep the outstanding Loans ratable in the event of any non-ratable increase in the aggregate Commitments, (i) all then outstanding Revolving Loans (the “Outstanding Loans”) shall, to the extent not then maintained as Base Rate Loans, automatically be converted into Base Rate Loans, (ii) immediately after the effectiveness of the Commitment Increase, the Borrower may, if it so requests, convert any such Base Rate Loans into LIBOR Loans in the amounts and for the Interest Periods specified in a Notice of Conversion/Continuation delivered to the Administrative Agent in accordance with Section 2.12, (iii) each Lender shall pay to the Administrative Agent in immediately available funds an amount equal to the difference, if positive, between (y) such Lender’s Ratable Share, calculated after giving effect to the Commitment Increase, of the Outstanding Loans and (z) such Lender’s Ratable Share, calculated without giving effect to the Commitment Increase, of the Outstanding Loans, (iv) after the Administrative Agent receives the funds specified in clause (iii) above, the Administrative Agent shall pay to each Lender the portion of such funds equal to the difference, if positive, between (y) such Lender’s Ratable Share, calculated without giving effect to the Commitment Increase, of the Outstanding Loans and (z) such Lender’s Ratable Share, calculated after giving effect to the Commitment Increase, of the amount of the Outstanding Loans, (v) the Lenders shall be deemed to hold the Outstanding Loans ratably in accordance with their respective Commitment (calculated after giving effect to the Commitment Increase), (vi) the Borrower shall pay all accrued but unpaid interest on the Outstanding Loans as of the Commitment Increase Date to the Lenders entitled thereto, and (vii) Schedule 1.1(a) shall automatically be amended to reflect the Commitments of all Lenders after giving effect to the Commitment Increase. The conversion of LIBOR Loans pursuant to clause (i) above shall be subject to indemnification by the Borrower pursuant to the provisions of Section 2.19 if the Commitment Increase Date occurs other than on the last day of the Interest Period relating thereto.

2.22Defaulting Lenders.

(a)Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i)Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Required Lenders and in Section 10.5.

(ii)Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VIII or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 8.3 shall be applied at such time or times as may be determined by the Administrative Agent as follows:

63

11863223v8 24740.00050

(A)first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder;

(B)second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Fronting Bank or the Swingline Lender hereunder;

(C)third, if so determined by the Administrative Agent or requested by the Fronting Bank or the Swingline Lender, to be held as Cash Collateral for the Fronting Exposure of the Fronting Bank or the Swingline Lender with respect to such Defaulting Lender in accordance with Section 2.22(c);

(D)fourth, as the Borrower may request (so long as no Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent;

(E)fifth, if so determined by the Administrative Agent or the Borrower, to be held in a non-interest bearing deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s future funding obligations with respect to Loans under this Agreement and (y) Cash Collateralize the Fronting Bank’s future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit Issued under this Agreement, in accordance with Section 2.22(c);

(F)sixth, to the payment of any amounts owing to the Lenders, the Fronting Bank or the Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the Fronting Bank or the Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement;

(G)seventh, so long as no Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and

(H)eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction;

provided that if (x) such payment is a payment of the principal amount of any Loans or any Letter of Credit Exposure in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 3.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and obligations in respect of Letters of Credit owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or obligations in respect of Letters of Credit owed to, such Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender

64

11863223v8 24740.00050

or to post Cash Collateral pursuant to this Section 2.22(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii)(23)    No Defaulting Lender shall be entitled to receive any Commitment Fee for any period during which such Lender is a Defaulting Lender and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to such Lender.

(A)Each Defaulting Lender shall be entitled to receive Letter of Credit Fees for any period during which such Lender is a Defaulting Lender only to the extent allocable to its Letter of Credit Exposure for which it has provided Cash Collateral in accordance with Section 2.22(c).

(B)With respect to any Commitment Fee or Letter of Credit Fee not required to be paid to any Defaulting Lender pursuant to Section 2.22(a)(iii)(A) or 2.22(a)(iii)(B), the Borrower shall (x) pay to each non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s Letter of Credit Exposure or Swingline Exposure that has been reallocated to such non-Defaulting Lender pursuant to Section 2.22(a)(iv), (y) pay to the Fronting Bank and the Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Fronting Bank’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender and (z) not be required to pay the remaining amount of any such fee.

(iv)All or any part of such Defaulting Lender’s Letter of Credit Exposure and Swingline Exposure shall automatically (effective on the day such Lender becomes a Defaulting Lender) be reallocated among the non-Defaulting Lenders in accordance with their respective Credit Exposures (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that such reallocation does not cause the Credit Exposure of any non-Defaulting Lender to exceed such non-Defaulting Lender’s Commitment.

(v)If the reallocation described in Section 2.22(a)(iv) cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, (A) first, prepay Swingline Loans in an amount equal to the Swingline Lender’s Fronting Exposure and (b) second, Cash Collateralize the Fronting Bank’s Fronting Exposure in accordance with the procedures set forth in Section 2.22(c).

(b)If the Borrower, the Administrative Agent, the Fronting Bank and the Swingline Lender agree in writing in their sole discretion that a Defaulting Lender should no longer be deemed to be a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Revolving Loans, Syndicated Letters of Credit and funded and unfunded participations in Participated Letters of Credit and Swingline Loans to be held on a pro rata basis by the Lenders in accordance with their respective

65

11863223v8 24740.00050

Credit Exposures (without giving effect to Section 2.22(a)(iii)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender; provided further that, except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender.

(c)At any time that there shall exist a Defaulting Lender, within two Business Days upon the request of the Administrative Agent, the Fronting Bank or the Swingline Lender, the Borrower shall deliver to the Administrative Agent Cash Collateral in an amount sufficient to cover all Fronting Exposure (after giving effect to Section 2.22(a)(iii) and any Cash Collateral provided by the Defaulting Lender).

(i)All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts with the Administrative Agent. The Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, the Fronting Bank and the Lenders (including the Swingline Lender), and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.22(c)(ii). If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby, the Borrower or the relevant Defaulting Lender will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency.

(ii)Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.22 in respect of Letters of Credit or Swingline Loans shall be held and applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in specific Letter of Credit Exposure or specific Swingline Exposure (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein.

Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee)) or (ii) the Administrative Agent’s good faith determination that there exists excess Cash Collateral; provided, however, that (x) Cash Collateral furnished by or on behalf of the Borrower shall not be released during the continuance of a Default (and following application as provided in this Section 2.22 may be otherwise applied in accordance with Section 2.13) and (y) the Person providing Cash Collateral and the Fronting

66

11863223v8 24740.00050

Bank or Swingline Lender, as applicable, may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

2.23Extension of Commitment Termination Date.

(a)The Borrower may, by notice to the Administrative Agent (who shall promptly notify the Lenders) given in writing not more than ninety (90) days and not later than thirty (30) days prior to any anniversary of the Closing Date (each such anniversary date, the relevant “Extension Date”), on no more than two (2) occasions during the term of this Agreement, request that each Lender extend such Lender’s Commitment Termination Date for a period of one (1) year from the Commitment Termination Date then in effect hereunder (the “Existing Commitment Termination Date”); provided that the Commitment Termination Date, after giving effect to any such extension, shall not be later than five (5) years after the effective date of such extension.

(i)Each Lender, acting in its sole and individual discretion, shall, by notice to the Administrative Agent given in writing not earlier than sixty (60) days prior to the Extension Date and not later than fifteen (15) days prior to the Extension Date (the date that is fifteen (15) days prior to the Extension Date being the “Notice Date”), advise the Administrative Agent if such Lender accepts the extension request from the Borrower (and each Lender that determines not to so extend its Commitment Termination Date (each, a “Non-Extending Lender”) shall notify the Administrative Agent of such fact promptly after such determination and in any event no later than the Notice Date) and any Lender that does not so advise the Administrative Agent on or before the Notice Date shall be deemed to be a Non-Extending Lender. The election of any Lender to agree to such extension shall not obligate any other Lender to so agree.

(ii)The Administrative Agent shall notify the Borrower of each Lender’s determination under this Section 2.23(a) no later than the date that is ten (10) days prior to the Extension Date (or, if such date is not a Business Day, on the next preceding Business Day).

(iii)The Borrower shall have the right on or before the Extension Date to replace each Non-Extending Lender with, and add as “Lenders” under this Agreement in place thereof, one or more Eligible Assignees (each, an “Additional Commitment Lender”) with the approval of the Administrative Agent, the Swingline Lender and the Fronting Bank (which approvals shall not be unreasonably withheld, conditioned or delayed), each of which Additional Commitment Lenders shall have entered into an agreement in form and substance reasonably satisfactory to the Borrower and the Administrative Agent pursuant to which such Additional Commitment Lender shall, effective as of the Extension Date, undertake a Commitment (and, if any such Additional Commitment Lender is already a Lender, its Commitment shall be in addition to such Lender’s Commitment hereunder on such date).

67

11863223v8 24740.00050

(iv)If (and only if) the total of the Commitments of the Lenders that have agreed to extend their Commitment Termination Date and the additional Commitments of the Additional Commitment Lenders shall be more than 50% of the aggregate amount of the Commitments in effect immediately prior to the Extension Date, then, effective as of the Extension Date, the Commitment Termination Date of each extending Lender and of each Additional Commitment Lender shall be extended to the date falling one (1) year after the Existing Commitment Termination Date (except that, if such date is not a Business Day, such Commitment Termination Date as so extended shall be the next preceding Business Day) and each Additional Commitment Lender shall thereupon become a “Lender” for all purposes of this Agreement and the other Credit Documents.

(v)Notwithstanding the foregoing, the extension of the Commitment Termination Date pursuant to this Section 2.23(a) shall not be effective with respect to any Lender unless:

(A)no Default or Event of Default shall have occurred and be continuing on the date of such extension and after giving effect thereto; and

(B)the representations and warranties contained in this Agreement are true and correct in all material respects (or if qualified by materiality or Material Adverse Effect, in all respects) on and as of the date of such extension and after giving effect thereto, as though made on and as of such date (or, if any such representation or warranty is expressly stated to have been made as of a specific date, as of such specific date).

(vi)On or before the Commitment Termination Date of each Non-Extending Lender, the Borrower shall pay in full (i) the principal of and interest on all of the Revolving Loans made by such Non-Extending Lender to the Borrower hereunder and (ii) all other amounts owing to such Lender hereunder.

74

11863223v8 24740.00050

therein not materially misleading in light of the circumstances under which the same were made; provided that, with respect to projected financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed by the Borrower to be reasonable at the time made. As of the Closing Date, there is no fact known to the Borrower that has, or would reasonably be expected to have, a Material Adverse Effect, which fact has not been set forth herein, in the financial statements of the Borrower and its Subsidiaries furnished to the Administrative Agent and/or the Lenders, or in any certificate, opinion or other written statement made or furnished by the Borrower to the Administrative Agent and/or the Lenders.

4.12Financial Matters.

(a)The Borrower has heretofore made available to the Administrative Agent copies of the audited consolidated balance sheets of the Borrower and its Subsidiaries for the fiscal years ending December 31, 2016, December 31, 2017 and December 31, 2018 and the related statements of income, stockholders’ equity and cash flows for the fiscal years or period then ended, together with the opinion of Ernst & Young LLP thereon. Such consolidated financial statements (A) have been prepared in accordance with GAAP (subject, with respect to the unaudited financial statements, to the absence of notes required by GAAP and to normal year-end adjustments) and (B) present fairly in all material respects the consolidated financial condition of the Borrower and its Subsidiaries, and the results of their operations and their cash flows, as of the dates and for the periods indicated.

(b)The Borrower has heretofore made available to the Administrative Agent copies of the Annual Statements of each Insurance Subsidiary that is a Material Subsidiary as of December 31, 2016, 2017 and 2018 for the fiscal years then ended, each as filed with the relevant Insurance Regulatory Authority (collectively, the “Historical Statutory Statements”). The Historical Statutory Statements (including, without limitation, the provisions made therein for investments and the valuation thereof, reserves, policy and contract claims and statutory liabilities) have been prepared, in all material respects, in accordance with SAP (except as may be reflected in the notes thereto), were in all material respects, in compliance with applicable Requirements of Law when filed and

75

11863223v8 24740.00050

present fairly in all material respects the financial condition of the respective Insurance Subsidiaries covered thereby as of the respective dates thereof and the results of operations, changes in capital and surplus and cash flows of the respective Insurance Subsidiaries covered thereby for the respective periods then ended. Except for liabilities and obligations disclosed or provided for in the Historical Statutory Statements (including, without limitation, reserves, policy and contract claims and statutory liabilities), no Insurance Subsidiary that is a Material Subsidiary had, as of the date of its respective Historical Statutory Statements, any material liabilities or obligations of any nature whatsoever (whether absolute, contingent or otherwise and whether or not due) that, in accordance with SAP, would have been required to have been disclosed or provided for in such Historical Statutory Statements.

4.13Ownership of Properties. The Borrower and each Material Subsidiary thereof (i) has good and marketable title to all real property owned by it, (ii) holds interests as lessee under valid leases in full force and effect with respect to all material leased real and personal property used in connection with its business, and (iii) has good title to all of its other material properties and assets necessary or used in the ordinary course of its business, except, with respect to the foregoing clauses (i) – (iii), such defects in title that would be a Permitted Liens hereunder or would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

4.14ERISA.

(a)The Borrower and each of its ERISA Affiliates is in compliance with the applicable provisions of ERISA, and each Plan is and has been administered in compliance with all applicable Requirements of Law, including, without limitation, the applicable provisions of ERISA and the Code, in each case except where the failure so to comply, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect. No ERISA Event (i) has occurred within the five year period prior to the Closing Date, (ii) has occurred and is continuing, or (iii) to the knowledge of the Borrower, is reasonably expected to occur with respect to any Plan, except where the occurrence of ERISA Events, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect. No Plan has any Unfunded Pension Liability as of the most recent annual valuation date applicable thereto, and neither the Borrower nor any of its ERISA Affiliates has engaged in a transaction that could be subject to Section 4069 or 4212(c) of ERISA, except where the incurrence of any Unfunded Pension Liability or liability in connection with such transactions, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect.

(b)Neither the Borrower nor any of its ERISA Affiliates has any outstanding liability on account of a complete or partial withdrawal from any Multiemployer Plan, and neither the Borrower nor any of its ERISA Affiliates would become subject to any liability under ERISA if any such Person were to withdraw completely from all Multiemployer Plans as of the most recent valuation date, except where the incurrence of any such liabilities, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect. No Multiemployer Plan is “insolvent” within the meaning of such term under ERISA, except where the existence of such insolvency, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect.

76

11863223v8 24740.00050

(c)The Borrower shall not use any of the “plan assets” (within the meaning of 29 CFR § 2510.3-101, as modified by Section 3(42) of ERISA or otherwise) of one or more of its Benefit Plans in connection with the Loans, the Letters of Credit or Commitments.

4.16Investment Company Act. Neither the Borrower nor any of its Domestic Insurance Subsidiaries is an “investment company,” a company “controlled” by an “investment company,” or an “investment advisor,” within the meaning of the Investment Company Act of 1940.

4.17Insurance. The assets, properties and business of the Borrower and each Material Subsidiary thereof are insured against such hazards and liabilities, under such coverages and in such amounts, as are customarily maintained by prudent companies similarly situated and under policies issued by insurers of recognized responsibility.

4.18Senior Debt Status. The Borrower’s obligations under this Agreement and each other Credit Document to which it is a party rank pari passu as to priority of payment and in all other respects with all other material unsecured and unsubordinated Indebtedness of the Borrower, with the exception of those obligations that are mandatorily preferred by law and not by contract.

4.19Anti-Corruption Laws; Anti-Money Laundering Laws and Sanctions.

(a)None of (i) the Borrower, any Subsidiary, or, to the knowledge of the Borrower or such Subsidiary, any of their respective directors, officers or employees, or (ii) to the knowledge of the Borrower or any Subsidiary, any agent or representative of the Borrower or any Subsidiary that will act in any capacity in connection with or benefit from this Agreement, (A) is a Sanctioned Person or currently the subject or target of any Sanctions, (B) is controlled by or is acting on behalf of a Sanctioned Person, (C) is under administrative, civil or criminal investigation for an alleged violation of, or received notice from or made a voluntary disclosure to any governmental entity regarding a possible violation of, Anti-Corruption Laws, Anti-Money Laundering Laws or Sanctions by a governmental authority that enforces Sanctions or any Anti-Corruption Laws or Anti-Money Laundering Laws or (D) directly or indirectly derives revenues from investments in, or transactions with, Sanctioned Persons.

(b)Each of the Borrower and its Subsidiaries has implemented and maintains in effect policies and procedures designed to ensure compliance by the Borrower and its Subsidiaries and their respective directors, officers, employees and agents with all applicable Anti-Corruption Laws, Anti-Money Laundering Laws and Sanctions.

ARTICLE IX

THE ADMINISTRATIVE AGENT

9.1Appointment and Authority. Each of the Lenders (for purposes of this Article, references to the Lenders shall also mean the Issuing Banks and the Swingline Lender) hereby irrevocably appoints Wells Fargo to act on its behalf as the Administrative Agent hereunder and under the other Credit Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. Except as set forth in Section 9.6, the provisions of this Article are solely for the benefit of the Administrative Agent and the Lenders, and neither the Borrower nor any other Unum Party shall have rights as a third party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” (or any other similar term) herein or in any other Credit Document with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations under agency doctrine of any applicable law. Instead, such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

9.2Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

9.3Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Credit Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

(a)shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has occurred and is continuing;

92

11863223v8 24740.00050

(b)shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Credit Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Credit Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Credit Document or applicable law, including, for the avoidance of doubt, any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

(c)shall not, except as expressly set forth herein and in the other Credit Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 10.5 and 8.2) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Administrative Agent in writing by the Borrower or a Lender.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Credit Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Credit Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

9.4Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of any Credit Extension that by its terms must be fulfilled to the satisfaction of a Lender or any Issuing Bank, the Administrative Agent may presume that such condition is satisfactory to such Lender or such Issuing Bank unless the Administrative Agent shall

93

11863223v8 24740.00050

have received notice to the contrary from such Lender or such Issuing Bank prior to the making of such Credit Extension. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

9.5Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Credit Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agent except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agent.

9.6Resignation of Administrative Agent.

(a)The Administrative Agent may at any time give notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower and subject to the approval of the Borrower (such approval not to be unreasonably withheld, conditioned or delayed), to appoint a successor Administrative Agent, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to), on behalf of the Lenders, appoint a successor Administrative Agent meeting the qualifications set forth above. Regardless of whether a successor has been appointed or has accepted such appointment, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b)With effect from the Resignation Effective Date, (i) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Credit Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lenders under any of the Credit Documents, the retiring Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (ii) except for any indemnity payments owed to the retiring Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for in Section9.6(a). Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to

94

11863223v8 24740.00050

and become vested with all of the rights, powers, privileges and duties of the retiring Administrative Agent (other than any rights to indemnity payments owed to the retiring Administrative Agent), and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Credit Documents. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Credit Documents, the provisions of this Article and Section 10.1 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

9.7Non-Reliance on Administrative Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Credit Document or any related agreement or any document furnished hereunder or thereunder.

9.8Administrative Agent May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to the Borrower, the Administrative Agent (irrespective of whether the principal of any Loan or Reimbursement Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated) by intervention in such proceeding or otherwise (i) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, Reimbursement Obligations and all other Obligations that are owing and unpaid and to file such other documents as may be necessary advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents, sub-agents and counsel and all other amounts due the Lenders and the Administrative Agent under Sections 2.10 and 10.1) allowed in such judicial proceeding and (ii) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents, sub-agents and counsel, and any other amounts due the Administrative Agent under Section 2.10 or 10.1.

9.9Issuing Bank and Swingline Lender. The provisions of this Article IX (other than Section9.2) shall apply to Wells Fargo as the Fronting Bank, LC Agent and the Swingline Lender

(ii)each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Commitment and/or Credit Extensions assigned, except that this clause (ii) shall not apply to rights in respect of Swingline Loans;

(iii)no consent shall be required for any assignment except to the extent required by clause (B) of Section 10.6(b)(i) and, in addition:

(A)the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (y) a Default or Event of Default has occurred and is continuing at the time of such assignment or (z) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within 10 Business Days after having received notice thereof;

(B)the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required if such assignment is to a Person that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender; and

104

11863223v8 24740.00050

(C)the consent of the Fronting Bank (such consent not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Participated Letters of Credit (whether or not then outstanding).

(iv)the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 for each assignment and the assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire and to the Administrative Agent and the Borrower such documentation required pursuant to Section 2.18(g);

(v)no such assignment shall be made to (A) the Borrower or any of its Affiliates or Subsidiaries or (B) any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B); and

(vi)no such assignment shall be made to a natural person (or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of a natural Person).

Subject to acceptance and recording thereof by the Administrative Agent pursuant to Section 10.6(d), from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.17(a), 2.17(b), 2.18, 2.19 and 10.1 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender. If requested by or on behalf of the assignee, the Borrower, at its own expense, will execute and deliver to the Administrative Agent a new Note or Notes to the order of the assignee (and, if the assigning Lender has retained any portion of its rights and obligations hereunder, to the order of the assigning Lender), prepared in accordance with the applicable provisions of Section 2.4 as necessary to reflect, after giving effect to the assignment, the Commitment and/or outstanding Credit Extensions, as the case may be, of the assignee and (to the extent of any retained interests) the assigning Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 10.6(b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 10.6(e).

105

11863223v8 24740.00050

(c)In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable Ratable Share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent or any Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full Ratable Share of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Credit Exposure. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable Law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

(d)The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at its address for notices referred to in Schedule 1.1(a) a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. In addition, the Administrative Agent shall maintain on the Register information regarding the designation, revocation of designation, of any Lender as a Defaulting Lender. The Register shall be available for inspection by each of the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(e)Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person (or a holding company, investment vehicle or trust for, or owned and operated for the primary benefit of a natural Person) or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Credit Extensions owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the L/C Agent, the Fronting Bank and the Swingline Lender and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, waiver or other modification

106

11863223v8 24740.00050

described in Section 10.5(a) and clause (i) of Section 10.5(b) that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.17(a), 2.17(b), 2.18 and 2.19 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 10.6(b); provided that such Participant (A) agrees to be subject to the provisions of Section 2.20 as if it were an assignee under Section 10.6(b) and (B) shall not be entitled to receive any greater payment under Section 2.17 or 2.18, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 2.20 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.3 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.16(b) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other Obligations under the Credit Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its other obligations under any Credit Document) to any Person except to the extent that such disclosure is necessary to establish such Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(f)Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Notes, if any) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(g)The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act or any state laws based on the Uniform Electronic Transactions Act.

(h)Any Lender or Participant may, in connection with any assignment, participation, pledge or proposed assignment, participation or pledge pursuant to this Section 10.6, disclose to the Eligible Assignee, Participant or pledgee or proposed Eligible Assignee, Participant or pledgee any information relating to the Borrower and its Subsidiaries furnished to it by or on behalf of any

107

11863223v8 24740.00050

other party hereto, provided that such Eligible Assignee, Participant or pledgee or proposed Eligible Assignee, Participant or pledgee agrees in writing to keep such information confidential to the same extent required of the Lenders under Section 10.11.

(i)Notwithstanding anything to the contrary contained herein, if Wells Fargo assigns all of its Commitment and Credit Extensions in accordance with this Section 10.6, Wells Fargo may resign as Fronting Bank, Swingline Lender and L/C Agent upon written notice to the Borrower and the Lenders. Upon any such notice of resignation, the Borrower shall have the right to appoint from among the Lenders a successor Fronting Bank, Swingline Lender and L/C Agent; provided that no failure by the Borrower to make such appointment shall affect the resignation of Wells Fargo as Fronting Bank, Swingline Lender and L/C Agent. Wells Fargo shall retain all of the rights and obligations of the Fronting Bank, Swingline Lender and L/C Agent hereunder with respect to all Letters of Credit issued by it or Swingline Loans made by it and outstanding as of the effective date of its resignation and all obligations of the Borrower and the Lenders with respect thereto.

10.7No Waiver. The rights and remedies of the Administrative Agent, the Issuing Banks and the Lenders expressly set forth in this Agreement and the other Credit Documents are cumulative and in addition to, and not exclusive of, all other rights and remedies available at law, in equity or otherwise. No failure or delay on the part of the Administrative Agent, any Issuing Bank or any Lender in exercising any right, power or privilege shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or privilege preclude other or further exercise thereof or the exercise of any other right, power or privilege or be construed to be a waiver of any Default or Event of Default. No course of dealing between the Borrower, the Administrative Agent, the Issuing Banks or the Lenders or their agents or employees shall be effective to amend, modify or discharge any provision of this Agreement or any other Credit Document or to constitute a waiver of any Default or Event of Default. No notice to or demand upon the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the right of the Administrative Agent, any Issuing Bank or any Lender to exercise any right or remedy or take any other or further action in any circumstances without notice or demand.

10.8Survival. All representations, warranties, covenants and agreements made by or on behalf of the Borrower in this Agreement and in the other Credit Documents shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery hereof or thereof and the making and repayment of the Loans and the Issuance of Letters of Credit and repayment of all Reimbursement Obligations, and shall continue in full force and effect as long as any Loan, Letter of Credit or any other Obligation hereunder shall remain unpaid or unsatisfied. In addition, notwithstanding anything herein or under applicable law to the contrary, the provisions of this Agreement and the other Credit Documents relating to indemnification or payment of costs and expenses, including, without limitation, the provisions of Sections 2.17(a), 2.17(b), 2.18, 2.19, 10.1 and Article IX, shall survive the payment in full of all Credit Extensions, the termination of the Commitments and all Letters of Credit, and any termination of this Agreement or any of the other Credit Documents or any provision hereof or thereof.

108

11863223v8 24740.00050

10.9Severability. To the extent any provision of this Agreement is prohibited by or invalid under the applicable law of any jurisdiction, such provision shall be ineffective only to the extent of such prohibition or invalidity and only in such jurisdiction, without prohibiting or invalidating such provision in any other jurisdiction or the remaining provisions of this Agreement in any jurisdiction. Without limiting the foregoing provisions of this Section 10.9, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by Debtor Relief Laws, as determined in good faith by the Administrative Agent, the Fronting Bank or the Swingline Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

10.10Construction. The headings of the various articles, sections and subsections of this Agreement and the table of contents have been inserted for convenience only and shall not in any way affect the meaning or construction of any of the provisions hereof. Except as otherwise expressly provided herein and in the other Credit Documents, in the event of any inconsistency or conflict between any provision of this Agreement and any provision of any of the other Credit Documents, the provision of this Agreement shall control.

10.11Confidentiality. Each of the Administrative Agent, the Issuing Banks and the Lenders agree to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent required or requested by any regulatory authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable Requirements of Law or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Credit Document or any action or proceeding relating to this Agreement or any other Credit Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, or (ii) any actual or prospective counterparty (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payments hereunder, (g) on a confidential basis, to (i) any rating agency in connection with the Borrower or its Subsidiaries or the facilities created hereunder or (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance monitoring of CUSIP numbers with respect to the facilities created hereunder; (h) with the consent of the Borrower or (i) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Administrative Agent, any Issuing Bank any Lender, or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower or any of its Subsidiaries or Affiliates that is not, to such Person’s knowledge, subject to confidentiality obligations to the Borrower.

109

11863223v8 24740.00050

basis prior to disclosure by any Unum Party. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

10.12Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Credit Documents constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof (except for the Fee Letters). Except as provided in Section 3.1, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement in electronic format (e.g., “pdf” or “tif” file format) shall be effective as delivery of a manually executed counterpart of this Agreement.

10.13No Fiduciary Relationship Established By Credit Documents. In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Credit Document), the Borrower acknowledges and agrees, and acknowledges its Affiliates’ understanding, that: (a) (i) no fiduciary, advisory or agency relationship between the Borrower and its Subsidiaries and any Arranger, the Administrative Agent, any Issuing Bank, any Swingline Lender or any Lender is intended to be or has been created in respect of the transactions contemplated hereby or by the other Credit Documents, irrespective of whether any Arranger, the Administrative Agent, any Issuing Bank, any Swingline Lender or any Lender has advised or is advising the Borrower or any Subsidiary on other matters, (ii) the arranging and other services regarding this Agreement provided by the Arrangers, the Administrative Agent, the Issuing Banks, the Swingline Lenders and the Lenders are arm’s-length commercial transactions between the Borrower and its Affiliates, on the one hand, and the Arrangers, the Administrative Agent, the Issuing Banks, the Swingline Lenders and the Lenders, on the other hand, (iii) the Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent that it has deemed appropriate and (iv) the Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by the other Credit Documents; and (b) (i) the Arrangers, the Administrative Agent, the Issuing Banks, the Swingline Lenders and the Lenders each is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for the Borrower or any of its Affiliates, or any other Person; (ii) none of the Arrangers, the Administrative Agent, the Issuing Banks, the Swingline Lenders and the Lenders has any obligation to the Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Credit Documents; and (iii) the Arrangers, the Administrative Agent, the Issuing Banks, the Swingline Lenders and the Lenders and their respective Affiliates may be engaged, for their own accounts or the accounts of customers, in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and none of the Arrangers, the Administrative Agent, the Issuing Banks, the Swingline Lenders and the Lenders has any obligation to disclose any of such

110

11863223v8 24740.00050

interests to the Borrower or its Affiliates. To the fullest extent permitted by Law, the Borrower hereby waives and releases any claims that it may have against any of the Arrangers, the Administrative Agent, the Issuing Banks, the Swingline Lenders and the Lenders with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

10.14Judgment Currency. If, for the purposes of obtaining judgment in any court or in respect of any tender made by the Borrower, it is necessary to convert a sum due hereunder or under any other Credit Document in one currency into another currency, the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase the first currency with such other currency on the Business Day preceding that on which final judgment is given or such tender is made. The obligation of the Borrower in respect of any such sum due from it to the Administrative Agent or any Lender hereunder or under the other Credit Documents shall, notwithstanding any tender or judgment in a currency (the “Judgment Currency”) other than that in which such sum is denominated in accordance with the applicable provisions of this Agreement (the “Agreement Currency”), be discharged only to the extent that on the Business Day following receipt by the Administrative Agent or such Lender of any sum received or adjudged to be so due in the Judgment Currency, the Administrative Agent or such Lender may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the sum originally due to the Administrative Agent or such Lender in the Agreement Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment or tender, to indemnify the Administrative Agent or such Lender or the Person to whom such obligation was owing against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to the Administrative Agent or such Lender in such currency, the Administrative Agent or such Lender agrees to return the amount of any excess to the Borrower (or to any other Person who may be entitled thereto under applicable law).

10.15Disclosure of Information. The Borrower agrees and consents to the Administrative Agent’s and the Arranger’s disclosure of information relating to this transaction to Gold Sheets and other similar bank trade publications. Such information will consist solely of deal terms and other information customarily found in such publications.

10.16Acknowledgement and Consent to Bail-In of EEA Financial Institutions. Notwithstanding anything to the contrary in any Credit Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under any Credit Document, to the extent such liability is unsecured, may be subject to the Write-Down and Conversion Powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

(a)the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and

(b)the effects of any Bail-in Action on any such liability, including, if applicable:

111

11863223v8 24740.00050

(i)a reduction in full or in part or cancellation of any such liability;

(ii)a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Credit Document; or

(iii)the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of any EEA Resolution Authority.

10.17PATRIOT Act Notice. Each Issuing Bank and each Lender that is subject to the PATRIOT Act and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the PATRIOT Act or any other Anti-Money Laundering Laws, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name, address, and taxpayer identification number of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the PATRIOT Act or such Anti-Money Laundering Laws.

10.18Amendment and Restatement; No Novation. This Agreement constitutes an amendment and restatement of the Existing Credit Agreement, effective from and after the Closing Date. The execution and delivery of this Agreement shall not constitute a novation of any indebtedness or other obligations owing to the Lenders or the Administrative Agent under the Existing Credit Agreement based on facts or events occurring or existing prior to the execution and delivery of this Agreement. On the Closing Date, the credit facilities described in the Existing Credit Agreement, shall be amended, supplemented, modified and restated in their entirety by the facilities described herein, and all loans, letters of credit and other obligations of the Borrower outstanding as of such date under the Existing Credit Agreement, shall be deemed to be loans, letters of credit and obligations outstanding under the corresponding facilities described herein, without any further action by any Person (including, without limitation, any Assignment and Assumption), except that the Administrative Agent shall make such transfers of funds as are necessary in order that the outstanding balance of the Revolving Loans, together with any Revolving Loans funded on the Closing Date, reflect the respective Commitments of the Lenders hereunder. The Letter of Credit Exposure of the Lenders in respect of the Existing Letters of Credit shall be automatically reallocated among the Lenders as of the Closing Date based on their pro rata shares of the Commitments as of the Closing Date.

Each of the Banks agrees, for itself alone and not jointly with any other Bank, to honor a draft drawn by you and presented to the L/C Agent in an amount not to exceed the aggregate amount available to be drawn hereunder multiplied by such Bank’s percentage obligation as set forth on Schedule 1 to this Letter of Credit (the “Percentage Obligations”) and in accordance with the terms and conditions hereinafter set forth. The obligations of the Banks hereunder shall be several and not joint, and multiple draws shall be available under this Letter of Credit. Upon the transfer by a Bank to the L/C Agent for your account of the amount specified in a draft drawn on such Bank hereunder, such Bank shall be fully discharged of its obligations under this Letter of Credit with respect to such draft, such Bank shall not be obligated thereafter to make any further payments under this Letter of Credit with respect to such draft, and the amount available to be drawn thereafter under this Letter of Credit shall be automatically and permanently reduced by an amount equal to the amount of such draft. The failure of any Bank to make funds available to the L/C Agent for payment under this Letter of Credit shall not relieve any other Bank of its obligation hereunder to make funds available to the L/C Agent. Neither the L/C Agent nor any Bank shall be responsible for the failure of any other Bank to honor its share of any drawings hereunder or to make funds available to the L/C Agent.

Except to the extent the amount of this Letter of Credit may be increased, this Letter of Credit cannot be modified or revoked without your written consent, provided that this Letter of Credit may be amended to delete a Bank or add a Bank or change Percentage Obligations so long as such amendment does not decrease the amount of this Letter of Credit, and need only be signed by the L/C Agent.

As L/C Agent, Wells Fargo Bank, National Association has full power of attorney from such Banks to act on their behalf hereunder to (i) execute and deliver this Letter of Credit, (ii) receive drafts, other demands for payment and other documents presented by you hereunder, (iii) determine whether such drafts, demands and documents are in compliance with the terms of this Letter of Credit, and (iv) notify the Banks and the Account Party that a valid drawing has been made and the date that the related payment under this Letter of Credit is to be made; provided, however, that the L/C Agent shall have no obligation or liability for any payment under this Letter of Credit (other than payment to you of such funds as have been made available to it by the Banks pursuant to your draw).

[This Letter of Credit expires on the Expiration Date, but will automatically renew without amendment for one year from the Expiration Date or any future expiration date (as applicable, the “New Expiration Date”) unless at least [30] [60] [90] days prior to such Expiration Date or New Expiration Date, the L/C Agent notifies you by registered mail or courier delivery that this Letter of Credit will not renew.]² 

Only the Beneficiary may make drawings under the Letter of Credit, and this Letter of Credit is not transferable.

Accounting Updates Adopted in 2019:

Accounting Standards Codification (ASC)	Description	Date of Adoption	Effect on Financial Statements
ASC 220 "Income Statement - Reporting Comprehensive Income"	This update allowed entities to make an accounting policy election to reclassify the disproportionate tax effects arising as a result of the recognition of the enactment of the tax bill, H.R.1, An Act to Provide Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018, more commonly known as the Tax Cuts and Jobs Act (TCJA) from accumulated other comprehensive income to retained earnings. Tax effects that are disproportionate in accumulated other comprehensive income for reasons other than the TCJA may not be reclassified. This update required additional disclosures on whether an entity elects to reclassify the disproportionate tax effects and its policy for releasing tax effects from accumulated other comprehensive income. This guidance was applied in the period of adoption.	January 1, 2019	The adoption of this update expanded certain of our disclosures but had no impact on our financial position or results of operations because we did not make the optional accounting policy election to reclassify the disproportionate tax effects resulting from the TCJA from accumulated other comprehensive income to retained earnings. We use an aggregate portfolio approach to release disproportionate tax effects when disposing of an entire business segment’s portfolio.
ASC 310 "Receivables - Nonrefundable Fees and Other Costs"	This update shortened the amortization period to the earliest call date for certain callable debt securities held at a premium. This update did not impact securities held at a discount. The guidance was applied in the period of adoption.	January 1, 2019	The adoption of this update did not have a material impact on our financial position or results of operations.
ASC 718 "Compensation - Stock Compensation"	This update generally aligned the accounting guidance for share-based payments issued to non-employees with guidance for share-based payments issued to employees. Specifically, the update required non-employee share-based payments to be measured using the grant date fair value of the equity instruments that an entity is obligated to issue when the good has been delivered or the service has been rendered rather than being remeasured through the performance completion date. Additionally, for non-employee share-based payments that contain performance conditions, the update changed the criteria regarding the recognition of compensation cost to when achievement of a performance condition is probable rather than upon actual achievement of the performance condition. The guidance was applied in the period of adoption.	January 1, 2019	The adoption of this update did not have an impact on our financial position or results of operations.

ASC	Description	Date of Adoption	Effect on Financial Statements
ASC 842 "Leases"	This update changed the accounting for leases, requiring lessees to report most leases on their balance sheets, regardless of whether the lease is classified as a finance lease or an operating lease. For lessees, the initial lease liability is equal to the present value of lease payments, and a corresponding asset, adjusted for certain items, is also recorded. Expense recognition for lessees remained similar to previous accounting requirements for capital and operating leases. For lessors, the guidance modified the classification criteria and the accounting for sales-type and direct financing leases. The guidance was applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings at the beginning of the period of adoption. In addition, the package of practical expedients available to leases that commenced prior to the date of adoption was applied.	January 1, 2019	See the summary table below for the financial statement impacts of this modified retrospective adoption on our financial statement line items at January 1, 2019. In addition, see Note 12 of the "Notes to Consolidated Financial Statements" contained herein in Item 1 for the additional disclosures required by the update.

Summary of Financial Statement Impacts of Accounting Updates adopted in 2018:

Effective January 1, 2018, we adopted an update under ASC 825 that changed the accounting and disclosure requirements for certain financial instruments. These changes included a requirement to measure equity investments, other than those that resulted in consolidation or are accounted for under the equity method, at fair value through net income unless the investment qualifies for certain practicability exceptions. The guidance was applied using a modified retrospective approach through a cumulative-effect reduction to accumulated other comprehensive income of $17.5 million with a corresponding increase to retained earnings of $14.5 million, a decrease to other long-term investments of $3.8 million, and a decrease to deferred income tax liability of $0.8 million.

Accounting Updates Outstanding:

ASC	Description	Date of Adoption	Effect on Financial Statements
ASC 326 "Financial Instruments - Credit Losses"	This update amends the guidance on the impairment of financial instruments. The update adds an impairment model known as the current expected credit loss model that is based on expected losses rather than incurred losses and will generally result in earlier recognition of allowances for losses. The current expected credit loss model applies to financial instruments such as mortgage loans, fixed maturity securities classified as held-to-maturity, and certain receivables. The update also modifies the other-than-temporary impairment model used for available-for-sale fixed maturity securities such that credit losses are recognized as an allowance rather than as a reduction in the amortized cost of the security. The reversal of previously recognized credit losses on available-for-sale fixed maturity securities is allowed under specified circumstances. Additional disclosures will also be required, including information used to develop the allowance for losses. The guidance is to be applied to most instruments in scope using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. For available-for-sale fixed maturity securities, the update is applied prospectively. Other-than-temporary impairment losses recognized on available-for-sale fixed maturity securities prior to adoption of the update cannot be reversed. Early adoption is permitted.	January 1, 2020	We have determined that this guidance is primarily applicable to our mortgage loan investments and reinsurance recoverables. We are currently developing and implementing systems to support the expected credit loss projections for these asset types. We continue to evaluate the expected impact on our financial position, results of operations, and disclosures.
ASC 350 "Intangibles - Goodwill and Other"	This update eliminates the requirement to calculate the implied fair value of goodwill (the second step in the current two-step test) to measure a goodwill impairment charge. Instead, entities should perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the excess of the carrying amount over the fair value, with the loss not to exceed the total amount of goodwill allocated to that reporting unit. The guidance is to be applied prospectively, with early adoption permitted for goodwill impairment tests performed on testing dates after January 1, 2017.	January 1, 2020	The adoption of this update will not have a material effect on our financial position or results of operations.

ASC	Description	Date of Adoption	Effect on Financial Statements
ASC 820 "Fair Value Measurement"	This update amended the fair value measurement guidance by removing or clarifying certain existing disclosure requirements, while also adding new disclosure requirements. Specifically, this update removed certain disclosures related to Level 1 and Level 2 transfers and also removed the discussion regarding valuation processes of Level 3 fair value measurements. The update modifies guidance related to investments in certain entities that calculate net asset value to explicitly require disclosure regarding timing of liquidation of the investee's assets and timing of redemption restrictions. The update adds disclosures around the changes in unrealized gains and losses in other comprehensive income for recurring Level 3 investments held at the end of the reporting period and adds disclosures regarding certain unobservable inputs on Level 3 fair value measurements. The guidance was applied retrospectively or prospectively depending on the specific requirement of the update. Entities are permitted to early adopt any removed or modified disclosures and may delay adoption of the additional disclosures until their effective date.	December 31, 2018 for the removal and modification of certain disclosures and January 1, 2020 for the addition of certain disclosures.	We elected to early adopt the removal and modification of disclosures, as permitted by the update. We have elected to delay the adoption of the additional disclosures until the effective date. The adoption of this update will modify our disclosures but will not have an impact on our financial position or results of operations.
ASC 715 "Compensation - Retirement Benefits"	This update amends the defined benefit pension and other postretirement benefit guidance by removing or clarifying certain existing disclosure requirements, while also adding new disclosure requirements. Specifically, this update removes the requirement to disclose the effects of a one-percentage point change in the assumed healthcare cost trend and the requirement to disclose amounts in accumulated other comprehensive income expected to be recognized as part of net periodic benefit cost of the next year. This update adds a requirement to describe the reasons for significant gains and losses related to changes in the benefit obligation for the period. The update also clarifies that the projected benefit obligation (PBO) and accumulated benefit obligation (ABO) and fair value of plan assets are to be disclosed for plans with PBOs or ABOs in excess of plan assets. The guidance is to be applied retrospectively and early adoption is permitted.	December 31, 2020	We have not yet determined the expected impact on our disclosures.

ASC	Description	Date of Adoption	Effect on Financial Statements
ASC 944 "Financial Services - Insurance"	This update significantly amends the accounting and disclosure requirements for long-duration insurance contracts. These changes include a requirement to review, and if necessary, update cash flow assumptions used to measure the liability for future policy benefits for traditional and limited-payment contracts at least annually, with changes recognized in earnings. In addition, an entity will be required to update the discount rate assumption at each reporting date using a yield that is reflective of an upper-medium grade fixed-income instrument, with changes recognized in other comprehensive income. These changes result in the elimination of the provision for risk of adverse deviation and premium deficiency (or loss recognition) testing. The update also requires that an entity measure all market risk benefits associated with deposit contracts at fair value, with changes recognized in earnings except for the portion attributable to a change in the instrument-specific credit risk, which is to be recognized in other comprehensive income. This update also simplifies the amortization of deferred acquisition costs by requiring amortization on a constant level basis over the expected term of the related contracts. Deferred acquisition costs are required to be written off for unexpected contract terminations but are no longer subject to an impairment test. Significant additional disclosures will also be required, which include disaggregated rollforwards of certain liability balances and the disclosure of qualitative and quantitative information about expected cash flows, estimates, and assumptions. The application of this guidance will vary based upon the specific requirements of the update but will generally result in either a modified retrospective or full retrospective approach with changes applied as of the beginning of the earliest period presented. Early adoption is permitted. * In July 2019, the Financial Accounting Standards Board (FASB) voted to propose a one-year deferral of the effective date to January 1, 2022. The FASB is expected to issue a final amendment later in 2019 regarding the proposed deferral date.	January 1, 2021*	We are currently evaluating the impact of the update and expect that the adoption may have a material impact on our financial position and results of operations. The update will also significantly expand our disclosures.

Fair Values of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Values of Financial Instruments

Fair Value Measurements for Financial Instruments Carried at Fair Value

We report fixed maturity securities, which are classified as available-for-sale securities, derivative financial instruments, and unrestricted equity securities at fair value in our consolidated balance sheets. We report our investments in private equity partnerships at our share of the partnerships' net asset value per share or its equivalent (NAV) as a practical expedient for fair value.

The degree of judgment utilized in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Financial instruments with readily available active quoted prices or for which fair value can be measured from actively quoted prices in active markets generally have more pricing observability and less judgment utilized in measuring fair value. An active market for a financial instrument is a market in which transactions for an asset or a similar asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and should be used to measure fair value whenever available. Conversely, financial instruments rarely traded or not quoted have less observability and are measured at fair value using valuation techniques that require more judgment. Pricing observability is generally impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, and overall market conditions.

We classify financial instruments in accordance with a fair value hierarchy consisting of three levels based on the observability of valuation inputs:

• Level 1 - the highest category of the fair value hierarchy classification wherein inputs are unadjusted and represent quoted prices in active markets for identical assets or liabilities at the measurement date.

• Level 2 - valued using inputs (other than prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument's anticipated life.

• Level 3 - the lowest category of the fair value hierarchy and reflects the judgment of management regarding what market participants would use in pricing assets or liabilities at the measurement date. Financial assets and liabilities categorized as Level 3 are generally those that are valued using unobservable inputs to extrapolate an estimated fair value.

Valuation Methodologies of Financial Instruments Measured at Fair Value

Valuation techniques used for assets and liabilities accounted for at fair value are generally categorized into three types. The market approach uses prices and other relevant information from market transactions involving identical or comparable assets or liabilities. The income approach converts future amounts, such as cash flows or earnings, to a single present amount, or a discounted amount. The cost approach is based upon the amount that currently would be required to replace the service capacity of an asset, or the current replacement cost.

We use valuation techniques that are appropriate in the circumstances and for which sufficient data are available that can be obtained without undue cost and effort. In some cases, a single valuation technique will be appropriate (for example, when valuing an asset or liability using quoted prices in an active market for identical assets or liabilities). In other cases, multiple valuation techniques will be appropriate. If we use multiple valuation techniques to measure fair value, we evaluate and weigh the results, as appropriate, considering the reasonableness of the range indicated by those results. A fair value measurement is the point within that range that is most representative of fair value in the circumstances.

The selection of the valuation method(s) to apply considers the definition of an exit price and depends on the nature of the asset or liability being valued. For assets and liabilities accounted for at fair value, we generally use valuation techniques consistent with the market approach, and to a lesser extent, the income approach. We believe the market approach provides more observable data than the income approach, considering the type of investments we hold. Our fair value measurements could differ significantly based on the valuation technique and available inputs. When using a pricing service, we obtain the vendor's pricing documentation to ensure we understand their methodologies. We periodically review and approve the selection of our pricing vendors to ensure we are in agreement with their current methodologies. When markets are less active, brokers may rely more on models with inputs based on the information available only to the broker. Our internal investment management professionals, which include portfolio managers and analysts, monitor securities priced by brokers and evaluate their prices for reasonableness based on benchmarking to available primary and secondary market information. In weighing a broker quote as an input to fair value, we place less reliance on quotes that do not reflect the result of market transactions. We also consider the nature of the quote, particularly whether the quote is a binding offer. If prices in an inactive market do not reflect current prices for the same or similar assets, adjustments may be necessary to arrive at fair value. When relevant market data is unavailable, which may be the case during periods of market uncertainty, the income approach can, in suitable circumstances, provide a more appropriate fair value. During 2019, we have applied valuation approaches and techniques on a consistent basis to similar assets and liabilities and consistent with those approaches and techniques used at year end 2018.

Fixed Maturity and Equity Securities

We use observable and unobservable inputs in measuring the fair value of our fixed maturity and equity securities. For securities categorized as Level 1, fair values equal active Trade Reporting and Compliance Engine (TRACE) pricing or unadjusted broker market maker prices. For securities categorized as Level 2 or Level 3, inputs that may be used in valuing each class of securities at any given time period are disclosed below. Actual inputs used to determine fair values will vary for each reporting period depending on the availability of inputs which may, at times, be affected by the lack of market liquidity.

The management of our investment portfolio includes establishing pricing policy and reviewing the reasonableness of sources and inputs used in developing pricing. We review all prices obtained to ensure they are consistent with a variety of observable market inputs and to verify the validity of a security's price.  In the event we receive a vendor's market price that does not appear reasonable based on our market analysis, we may challenge the price and request further information about the assumptions and methodologies used by the vendor to price the security. We may change the vendor price based on a better data source such as an actual trade. We also review all price changes from the prior month which fall outside a predetermined corridor. The overall valuation process for determining fair values may include adjustments to valuations obtained from our pricing sources when they do not represent a valid exit price. These adjustments may be made when, in our judgment and considering our knowledge of the financial conditions and industry in which the issuer operates, certain features of the financial instrument require that an adjustment be made to the value originally obtained from our pricing sources. These features may include the complexity of the financial instrument, the market in which the financial instrument is traded, counterparty credit risk, credit structure, concentration, or liquidity. Additionally, an adjustment to the price derived from a model typically reflects our judgment of the inputs that other participants in the market for the financial instrument being measured at fair value would consider in pricing that same financial instrument. In the event an asset is sold, we test the validity of the fair value determined by our valuation techniques by comparing the selling price to the fair value determined for the asset in the immediately preceding month end reporting period.

Certain of our investments do not have readily determinable market prices and/or observable inputs or may at times be affected by the lack of market liquidity. For these securities, we use internally prepared valuations combining matrix pricing with vendor purchased software programs, including valuations based on estimates of future profitability, to estimate the fair value. Additionally, we may obtain prices from independent third-party brokers to aid in establishing valuations for certain of these securities. Key assumptions used by us to determine fair value for these securities include risk free interest rates, risk premiums, performance of underlying collateral (if any), and other factors involving significant assumptions which may or may not reflect those of an active market.

The parameters and inputs used to validate a price on a security may be adjusted for assumptions about risk and current market conditions on a quarter to quarter basis, as certain features may be more significant drivers of valuation at the time of pricing. Changes to inputs in valuations are not changes to valuation methodologies; rather, the inputs are modified to reflect direct or indirect impacts on asset classes from changes in market conditions.

At June 30, 2019, 23.6 percent of our fixed maturity securities were valued using active trades from TRACE pricing or broker market maker prices for which there was current market activity in that specific security (comparable to receiving one binding quote).  The prices obtained were not adjusted, and the assets were classified as Level 1.

The remaining 76.4 percent of our fixed maturity securities were valued based on non-binding quotes or other observable and unobservable inputs, as discussed below:

• 63.1 percent of our fixed maturity securities were valued based on prices from pricing services that generally use observable inputs such as prices for securities or comparable securities in active markets in their valuation techniques. These assets were classified as Level 2. 

• 3.7 percent of our fixed maturity securities were valued based on one or more non-binding broker quotes, if validated by observable market data, or on TRACE prices for identical or similar assets absent current market activity. When only one price is available, it is used if observable inputs and analysis confirms that it is appropriate. These assets, for which we were able to validate the price using other observable market data, were classified as Level 2.

• 9.6 percent of our fixed maturity securities were valued based on prices of comparable securities, matrix pricing, market models, and/or internal models or were valued based on non-binding quotes with no other observable market data. These assets were classified as either Level 2 or Level 3, with the categorization dependent on whether there was other observable market data.  

Derivatives

Fair values for derivatives other than embedded derivatives in modified coinsurance arrangements are based on market quotes or pricing models and represent the net amount of cash we would have paid or received if the contracts had been settled or closed as of the last day of the period. We analyze credit default swap spreads relative to the average credit spread embedded within the LIBOR-setting syndicate in determining the effect of credit risk on our derivatives' fair values.  If net counterparty credit risk for a derivative asset is determined to be material and is not adequately reflected in the LIBOR-based fair value obtained from our pricing sources, we adjust the valuations obtained from our pricing sources. For purposes of valuing net counterparty risk, we measure the fair value of a group of financial assets and financial liabilities on the basis of the price that would be received to sell a net long position or transfer a net short position for a particular risk exposure in an orderly transaction between market participants at the measurement date under current market conditions. In regard to our own credit risk component, we adjust the valuation of derivative liabilities wherein the counterparty is exposed to our credit risk when the LIBOR-based valuation of our derivatives obtained from pricing sources does not effectively include an adequate credit component for our own credit risk.

Fair values for our embedded derivative in a modified coinsurance arrangement are estimated using internal pricing models and represent the hypothetical value of the duration mismatch of assets and liabilities, interest rate risk, and third party credit risk embedded in the modified coinsurance arrangement.

We consider transactions in inactive markets to be less representative of fair value. We use all available observable inputs when measuring fair value, but when significant unobservable inputs are used, we classify these assets or liabilities as Level 3.

Private Equity Partnerships

Our private equity partnerships represent funds that are primarily invested in private credit, private equity, and real assets, as described below. Distributions received from the funds arise from income generated by the underlying investments as well as the liquidation of the underlying investments. There is generally not a public market for these investments.

The following tables present additional information about our private equity partnerships, including commitments for additional investments which may or may not be funded:

Realized and unrealized investment gains and losses presented in the preceding tables represent gains and losses only for the time during which the applicable financial instruments were classified as Level 3. The transfers between levels resulted primarily from a change in observability of three inputs used to determine fair values of the securities transferred: (1) transactional data for new issuance and secondary trades, (2) broker/dealer quotes and pricing, primarily related to changes in the level of activity in the market and whether the market was considered orderly, and (3) comparable bond metrics from which to perform an analysis. For fair value measurements of financial instruments that were transferred either into or out of Level 3, we reflect the transfers using the fair value at the beginning of the period. We believe this allows for greater transparency, as all changes in fair value that arise during the reporting period of the transfer are disclosed as a component of our Level 3 reconciliation. Gains (losses) which are included in earnings and are attributable to the change in fair value of assets or liabilities valued using significant unobservable inputs and still held at period end were $(0.8) million and $4.7 million for the three and six months ended June 30, 2019, respectively, and $(2.3) million and $(4.0) million for the three and six months ended June 30, 2018, respectively. These amounts relate entirely to the change in fair value of an embedded derivative in a modified coinsurance arrangement and are reported as a component of realized investment gains and losses.

The table below provides quantitative information regarding the significant unobservable inputs used in Level 3 fair value measurements derived from internal models. Certain securities classified as Level 3 are excluded from the table below due to limitations in our ability to obtain the underlying inputs used by external pricing sources.

(b) Represents basis point adjustments for credit-specific factors

(c) Represents a decision to price based on par value, cost, or owner's equity when limited data is available

(d) Represents various actuarial assumptions required to derive the liability cash flows including incidence, termination, and lapse rates

Isolated increases in unobservable inputs other than market convention will result in a lower fair value measurement, whereas isolated decreases will result in a higher fair value measurement. The unobservable input for market convention is not sensitive to input movements. The projected liability cash flows used in the fair value measurement of our Level 3 embedded derivative are based on expected claim payments. If claim payments increase, the projected liability cash flows will increase, resulting in a decrease in the fair value of the embedded derivative. Decreases in projected liability cash flows will result in an increase in the fair value of the embedded derivative.

Fair Value Measurements for Financial Instruments Not Carried at Fair Value

The methods and assumptions used to estimate fair values of financial instruments not carried at fair value are discussed as follows:

Mortgage Loans: Fair values are estimated using discounted cash flow analyses and interest rates currently being offered for similar loans to borrowers with similar credit ratings and maturities. Loans with similar characteristics are aggregated for purposes of the calculations.

Policy Loans: Fair values for policy loans, net of reinsurance ceded, are estimated using discounted cash flow analyses and interest rates currently being offered to policyholders with similar policies. Carrying amounts for ceded policy loans, which equal $3,348.0 million and $3,449.3 million as of June 30, 2019 and December 31, 2018, respectively, approximate fair value and are reported on a gross basis in our consolidated balance sheets. A change in interest rates for ceded policy loans will not impact our financial position because the benefits and risks are fully ceded to reinsuring counterparties.

Miscellaneous Long-term Investments: Carrying amounts for tax credit partnerships equal the unamortized balance of our contractual commitments and approximate fair value. Our shares of FHLB common stock are carried at cost, which approximates fair value.

Long-term Debt: Fair values for long-term debt are obtained from independent pricing services or discounted cash flow analyses based on current incremental borrowing rates for similar types of borrowing arrangements.

FHLB Funding Agreements: Funding agreements with the FHLB represent cash advances used for the purpose of investing in fixed maturity securities. Carrying amounts approximate fair value.

Unfunded Commitments to Investment Partnerships: Unfunded equity commitments represent amounts that we have committed to fund certain investment partnerships. These commitments are legally binding, subject to the partnerships meeting specified conditions. Carrying amounts of these financial instruments approximate fair value.

The following table presents the carrying amounts and estimated fair values of our financial instruments not measured at fair value and indicates the level in the fair value hierarchy of the estimated fair value measurement based on the observability of the inputs used:

Total Financial Instrument Liabilities Not Carried at Fair Value	$	1,429.8	$	1,745.7	$	—	$	3,175.5	$	3,077.6

The carrying values of financial instruments such as short-term investments, cash and bank deposits, accounts and premiums receivable, accrued investment income, securities lending agreements, and short-term debt approximate fair value due to the short-term nature of the instruments. As such, these financial instruments are not included in the above chart.

Fair values for insurance contracts other than investment contracts are not required to be disclosed. However, the fair values of liabilities under all insurance contracts are taken into consideration in our overall management of interest rate risk, which seeks to minimize exposure to changing interest rates through the matching of investment maturities with amounts due under insurance contracts.

The following chart depicts an analysis of our fixed maturity security portfolio between investment-grade and below-investment-grade categories as of June 30, 2019:

					Gross Unrealized Loss
	Fair Value		Gross Unrealized Gain		Amount		Percent of Total Gross Unrealized Loss
	(in millions of dollars)
Investment-Grade	$	43,232.8	$	5,664.6	$	58.5	39.4	%
Below-Investment-Grade	3,207.4		119.2		89.9		60.6
Total Fixed Maturity Securities	$	46,440.2	$	5,783.8	$	148.4	100.0	%

The unrealized losses on investment-grade fixed maturity securities principally relate to changes in interest rates or changes in market or sector credit spreads which occurred subsequent to the acquisition of the securities. Below-investment-grade fixed maturity securities are generally more likely to develop credit concerns than investment-grade securities. At June 30, 2019, the unrealized losses in our below-investment-grade fixed maturity securities were generally due to credit spreads in certain industries or sectors and, to a lesser extent, credit concerns related to specific securities. For each specific security in an unrealized loss position, we believe that there are positive factors which mitigate credit concerns and that the securities for which we have not recorded an other-than-temporary impairment will recover in value.

As of June 30, 2019, we held 105 individual investment-grade fixed maturity securities and 51 individual below-investment-grade fixed maturity securities that were in an unrealized loss position, of which 59 investment-grade fixed maturity securities and 41 below-investment-grade fixed maturity securities had been in an unrealized loss position continuously for over one year.

In determining when a decline in fair value below amortized cost of a fixed maturity security is other than temporary, we evaluate the following factors:

• Whether we expect to recover the entire amortized cost basis of the security

• Whether we intend to sell the security or will be required to sell the security before the recovery of its amortized cost basis

• Whether the security is current as to principal and interest payments

• The significance of the decline in value

• The time period during which there has been a significant decline in value

• Current and future business prospects and trends of earnings

• The valuation of the security's underlying collateral

• Relevant industry conditions and trends relative to their historical cycles

• Market conditions

• Rating agency and governmental actions

• Bid and offering prices and the level of trading activity

• Adverse changes in estimated cash flows for securitized investments

• Changes in fair value subsequent to the balance sheet date

• Any other key measures for the related security

While determining other-than-temporary impairments is a judgmental area, we utilize a formal, well-defined, and disciplined process to monitor and evaluate our fixed income investment portfolio, supported by issuer specific research and documentation as of the end of each period. The process results in a thorough evaluation of problem investments and the recording of losses on a timely basis for investments determined to have an other-than-temporary impairment.

We held no fixed maturity securities as of June 30, 2019 or December 31, 2018 for which a portion of an other-than-temporary impairment was recognized in accumulated other comprehensive income.

At June 30, 2019, we had commitments of $103.5 million to fund private placement fixed maturity securities, the amount of which may or may not be funded. 

Variable Interest Entities

We invest in variable interests issued by variable interest entities. These investments include tax credit partnerships, private equity partnerships, and special purpose entities. For those variable interests that are not consolidated in our financial statements, we are not the primary beneficiary because we have neither the power to direct the activities that are most significant to economic performance nor the responsibility to absorb a majority of the expected losses. The determination of whether we are the primary beneficiary is performed at the time of our initial investment and at the date of each subsequent reporting period.

As of June 30, 2019, the carrying amount of our variable interest entity investments that are not consolidated in our financial statements was $614.9 million, comprised of $74.6 million of tax credit partnerships and $540.3 million of private equity partnerships. At December 31, 2018, the carrying amount of our variable interest entity investments that are not consolidated in our financial statements was $575.3 million, comprised of $91.5 million of tax credit partnerships and $483.8 million of private equity partnerships. These variable interest entity investments are reported as other long-term investments in our consolidated balance sheets.

The Company invests in tax credit partnerships primarily for the receipt of income tax credits and tax benefits derived from passive losses on the investments. Amounts recognized in the consolidated statements of income are as follows:

	Three Months Ended June 30						Six Months Ended June 30
	2019			2018			2019			2018
	(in millions of dollars)
Income Tax Credits	$	9.4		$	10.3		$	18.8		$	20.7
Amortization, net of tax	(6.1		)	(7.0		)	(12.9		)	(14.0		)
Income Tax Benefit	$	3.3		$	3.3		$	5.9		$	6.7

Contractually, we are a limited partner in these tax credit partnerships, and our maximum exposure to loss is limited to the carrying value of our investment, which includes $2.3 million of unfunded unconditional commitments at June 30, 2019. See Note 3 for commitments to fund private equity partnerships.

We are the sole beneficiary of a special purpose entity which is consolidated in our financial statements.  This entity is a securitized asset trust containing a highly rated bond for principal protection which we contributed into the trust at the time it was established.  There are no restrictions on the asset held in this trust, and the trust is free to dispose of the asset at any time.  The fair values of the bond were $159.0 million and $156.7 million as of June 30, 2019 and December 31, 2018, respectively.  The bond is reported as a component of fixed maturity securities in our consolidated balance sheets.

Mortgage Loans

Our mortgage loan portfolio is well diversified by both geographic region and property type to reduce risk of concentration. All of our mortgage loans are collateralized by commercial real estate. When issuing a new loan, our general policy is not to exceed a loan-to-value ratio, or the ratio of the loan balance to the estimated fair value of the underlying collateral, of 75 percent. We update the loan-to-value ratios at least every three years for each loan, and properties undergo a general inspection at least every two years. Our general policy for newly issued loans is to have a debt service coverage ratio greater than 1.25 times on a normalized 25 year amortization period. We update our debt service coverage ratios annually. Mortgage loans by property type and geographic region are presented below.

We evaluate each of our mortgage loans individually for impairment and assign an internal credit quality rating based on a comprehensive rating system used to evaluate the credit risk of the loan. The factors we use to derive our internal credit ratings may include the following:

• Loan-to-value ratio

• Debt service coverage ratio based on current operating income

• Property location, including regional economics, trends and demographics

• Age, condition, and construction quality of property

• Current and historical occupancy of property

• Lease terms relative to market

• Tenant size and financial strength

• Borrower's financial strength

• Borrower's equity in transaction

• Additional collateral, if any

Although all available and applicable factors are considered in our analysis, loan-to-value and debt service coverage ratios are the most critical factors in determining whether we will initially issue the loan and also in assigning values and determining impairment. We assign an overall rating to each loan using an internal rating scale of Aa (highest quality) to B (lowest quality). We review and adjust, as needed, our internal credit quality ratings on an annual basis. This review process is performed more frequently for mortgage loans deemed to have a higher risk of delinquency.

Mortgage loans, sorted by the applicable credit quality indicators, are as follows:

	June 30, 2019		December 31, 2018
	(in millions of dollars)
Internal Rating
A	$	390.8	$	477.5

Total	$	2,218.9	$	2,295.0

There were no troubled debt restructurings during the three and six months ended June 30, 2019. We had one mortgage loan which was modified in a troubled debt restructuring during the second quarter of 2018. The loan had a principal balance of $3.6 million prior to the restructuring, wherein the terms of the loan were modified to reduce monthly payments to interest-only at the current note rate and to permit a discounted payoff by September 2018. We recorded an allowance for credit losses on mortgage loans for this restructuring and recognized an impairment loss of $0.2 million in the second quarter of 2018.

At June 30, 2019, we held no mortgage loans that were greater than 90 days past due regarding principal and/or interest payments. At December 31, 2018, we held one mortgage loan that was greater than 90 days past due regarding principal and/or interest payments which was settled during the first quarter of 2019 resulting in an additional loss of $0.1 million.

Our average investment in impaired mortgage loans was zero and $1.1 million for the three and six months ended June 30, 2019, respectively. Our average investment in impaired mortgage loans was $1.1 million for the three and six months ended June 30, 2018. We did not recognize any interest income on mortgage loans subsequent to impairment during the three and six months ended June 30, 2019 or 2018.

There have been no changes to our accounting policies or methodology from the prior period regarding estimating the allowance for credit losses on our mortgage loans. The activity in the allowance for credit losses is as follows:

	Three Months Ended June 30				Six Months Ended June 30

At June 30, 2019, we had commitments of $87.1 million to fund certain commercial mortgage loans, the amount of which may or may not be funded.

Transfers of Financial Assets

To manage our cash position more efficiently, we may enter into repurchase agreements with unaffiliated financial institutions. We generally use repurchase agreements as a means to finance the purchase of invested assets or for short-term general business purposes until projected cash flows become available from our operations or existing investments. Our repurchase agreements are typically outstanding for less than 30 days. We post collateral through our repurchase agreement transactions whereby the counterparty commits to purchase securities with the agreement to resell them to us at a later, specified date. The fair value of collateral posted is generally 102 percent of the cash received.

Our investment policy also permits us to lend fixed maturity securities to unaffiliated financial institutions in short-term securities lending agreements. These agreements increase our investment income with minimal risk. Our securities lending policy requires that a minimum of 102 percent of the fair value of the securities loaned be maintained as collateral. We may receive cash and/or securities as collateral under these agreements. Cash received as collateral is typically reinvested in short-term investments. If securities are received as collateral, we are not permitted to sell or re-post them.

As of June 30, 2019, the carrying amount of fixed maturity securities loaned to third parties under our securities lending program was $266.7 million, for which we received collateral in the form of cash and securities of $5.8 million and $274.5 million, respectively. As of December 31, 2018, the carrying amount of fixed maturity securities loaned to third parties under our securities lending program was $164.1 million, for which we received collateral in the form of cash and securities of $0.1 million and $171.4 million, respectively. We had no outstanding repurchase agreements at June 30, 2019 or December 31, 2018.

The remaining contractual maturities of our securities lending agreements disaggregated by class of collateral pledged are as follows:

Certain of our U.S. insurance subsidiaries are members of regional FHLBs. Membership, which requires that we purchase a minimum amount of FHLB common stock on which we receive dividends, provides access to low-cost funding. Advances received from the FHLB are used for the purchase of fixed maturity securities. Additional common stock purchases may be required, based on the amount of funds we borrow from the FHLBs. The carrying value of common stock owned, collateral posted, and advances received are as follows:

Offsetting of Financial Instruments

We enter into master netting agreements with each of our derivatives counterparties. These agreements provide for conditional rights of set-off upon the occurrence of an early termination event. An early termination event is considered a default, and it allows the non-defaulting party to offset its contracts in a loss position against any gain positions or payments due to the defaulting party. Under our agreements, default type events are defined as failure to pay or deliver as contractually agreed, misrepresentation, bankruptcy, or merger without assumption. See Note 5 for further discussion of collateral related to our derivative contracts.

We have securities lending agreements with unaffiliated financial institutions that post collateral to us in return for the use of our fixed maturity securities. A right of set-off exists that allows us to keep and apply collateral received in the event of default by the counterparty. Default within a securities lending agreement would typically occur if the counterparty failed to return the securities borrowed from us as contractually agreed. In addition, if we default by not returning collateral received, the counterparty has a right of set-off against our securities or any other amounts due to us.

Shown below are our financial instruments that either meet the accounting requirements that allow them to be offset in our balance sheets or that are subject to an enforceable master netting arrangement or similar agreement. Our accounting policy is to not offset these financial instruments in our balance sheets. Net amounts disclosed below have been reduced by the amount of collateral pledged to or received from our counterparties.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Purpose of Derivatives

We are exposed to certain risks relating to our ongoing business operations. The primary risks managed by using derivative instruments are interest rate risk, risk related to matching duration for our assets and liabilities, foreign currency risk, and credit risk. Historically, we have utilized current and forward interest rate swaps, current and forward currency swaps, forward benchmark interest rate locks, currency forward contracts, forward contracts on specific fixed income securities, and credit default swaps. Transactions hedging interest rate risk are primarily associated with our individual and group long-term care and individual and group disability products. All other product portfolios are periodically reviewed to determine if hedging strategies would be appropriate for risk management purposes. We do not use derivative financial instruments for speculative purposes.

Derivatives designated as cash flow hedges and used to reduce our exposure to interest rate and duration risk are as follows:

• Interest rate swaps are used to hedge interest rate risks and to improve the matching of assets and liabilities. An interest rate swap is an agreement in which we agree with other parties to exchange, at specified intervals, the difference between fixed rate and variable rate interest amounts. We use interest rate swaps to hedge the anticipated purchase of fixed maturity securities thereby protecting us from the potential adverse impact of declining interest rates on the associated policy reserves. We also use interest rate swaps to hedge the potential adverse impact of rising interest rates in anticipation of issuing fixed rate long-term debt.

• Forward benchmark interest rate locks are used to minimize interest rate risk associated with the anticipated purchase or disposal of fixed maturity securities. A forward benchmark interest rate lock is a derivative contract without an initial investment where we and the counterparty agree to purchase or sell a specific benchmark interest rate bond at a future date at a pre-determined price.

Derivatives designated as fair value hedges and used to reduce our exposure to interest rate and duration risk are as follows:

• Interest rate swaps are used to effectively convert certain of our fixed rate securities into floating rate securities which are used to fund our floating rate long-term debt. Under these swap agreements, we receive a variable rate of interest and pay a fixed rate of interest. Additionally, we use interest rate swaps to effectively convert certain fixed rate, long-term debt into floating rate long-term debt. Under these swap agreements, we receive a fixed rate of interest and pay a variable rate of interest.

Derivatives designated as either cash flow or fair value hedges and used to reduce our exposure to foreign currency risk are as follows:

• Foreign currency interest rate swaps are used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification. Under these swap agreements, we agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment.

Derivatives not designated as hedging instruments and used to reduce our exposure to foreign currency risk, credit losses on securities owned, and interest rate risk are as follows:

• Foreign currency interest rate swaps previously designated as hedges were used to hedge the currency risk of certain foreign currency-denominated fixed maturity securities owned for portfolio diversification. These derivatives were effective hedges prior to novation to a new counterparty. In conjunction with the novation, these derivatives were de-designated as hedges. We agree to pay, at specified intervals, fixed rate foreign currency-denominated principal and interest payments in exchange for fixed rate payments in the functional currency of the operating segment. We hold offsetting swaps wherein we agree to pay fixed rate principal and interest payments in the functional currency of the operating segment in exchange for fixed rate foreign currency-denominated payments.

• Credit default swaps are used as economic hedges against credit risk but do not qualify for hedge accounting. A credit default swap is an agreement in which we agree with another party to pay, at specified intervals, a fixed-rate fee in exchange for insurance against a credit event on a specific investment. If a defined credit event occurs, our counterparty may either pay us a net cash settlement or we may surrender the specific investment to them in exchange for cash equal to the full notional amount of the swap. Credit events typically include events such as bankruptcy, failure to pay, or certain types of debt restructuring.

• Interest rate swap was used to effectively convert certain of our floating rate, long-term debt into fixed rate long-term debt. Under this swap agreement, we received a variable rate of interest and paid a fixed rate of interest.

• Foreign currency forward contracts are used to minimize foreign currency risk. A foreign currency forward is a derivative without an initial investment where we and the counterparty agree to exchange a specific amount of currencies, at a specific exchange rate, on a specific date. We use these forward contracts to hedge the currency risk arising from foreign-currency denominated securities.

Derivative Risks

The basic types of risks associated with derivatives are market risk (that the value of the derivative will be adversely impacted by changes in the market, primarily the change in interest and exchange rates) and credit risk (that the counterparty will not perform according to the terms of the contract). The market risk of the derivatives should generally offset the market risk associated with the hedged financial instrument or liability. To help limit the credit exposure of the derivatives, we enter into master netting agreements with our counterparties whereby contracts in a gain position can be offset against contracts in a loss position. We also typically enter into bilateral, cross-collateralization agreements with our counterparties to help limit the credit exposure of the derivatives. These agreements require the counterparty in a loss position to submit acceptable collateral with the other counterparty in the event the net loss position meets or exceeds an agreed upon amount. Credit exposure on derivatives is limited to the value of those contracts in a net gain position, including accrued interest receivable less collateral held. At June 30, 2019, we had no credit exposure on derivatives. As of December 31, 2018, we had $0.9 million credit exposure on derivatives. The table below summarizes the nature and amount of collateral received from and posted to our derivative counterparties.

	June 30, 2019		December 31, 2018

Carrying Value of Collateral Received from Counterparties
Cash	$	22.3	$	24.0
Carrying Value of Collateral Posted to Counterparties
Fixed Maturity Securities	$	30.4	$	33.4

See Note 4 for further discussion of our master netting agreements.

The majority of our derivative instruments contain provisions that require us to maintain specified issuer credit ratings and financial strength ratings. Should our ratings fall below these specified levels, we would be in violation of the provisions, and our derivatives counterparties could terminate our contracts and request immediate payment. The aggregate fair value of all derivative instruments with credit risk-related contingent features that were in a liability position was $36.2 million and $38.0 million at June 30, 2019 and December 31, 2018, respectively.

Cash Flow Hedges

As of June 30, 2019 and December 31, 2018, we had $232.9 million and $286.4 million, respectively, notional amount of receive fixed, pay fixed, open current and forward foreign currency interest rate swaps to hedge fixed income foreign currency-denominated securities.

As of June 30, 2019, we expect to amortize approximately $71.7 million of net deferred gains on derivative instruments during the next twelve months. This amount will be reclassified from accumulated other comprehensive income into earnings and reported on the same income statement line item as the hedged item. The income statement line items that will be affected by this amortization are net investment income and interest and debt expense. Additional amounts that may be reclassified from accumulated other comprehensive income into earnings to offset the earnings impact of foreign currency translation of hedged items are not estimable.

As of June 30, 2019, we are hedging the variability of future cash flows associated with forecasted transactions through the year 2045.

Fair Value Hedges

As of June 30, 2019 and December 31, 2018, we had $177.7 million and $78.1 million respectively, notional amount of receive fixed, pay fixed, open current and forward foreign currency interest rate swaps to hedge fixed income foreign currency-denominated securities.

As of June 30, 2019 and December 31, 2018, we had $250.0 million notional amount of receive fixed, pay variable interest rate swaps to hedge the changes in the fair value of certain fixed rate long-term debt. These swaps effectively convert the associated fixed rate long-term debt into floating rate debt and provide for a better matching of interest rates with our short-term investments, which have frequent interest rate resets similar to a floating rate security.

The following table summarizes the carrying amount of hedged assets and liabilities and the related cumulative basis adjustments related to our fair value hedges.

	Carrying Amount of Hedged Assets (Liabilities)						Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets (Liabilities)
	June 30, 2019			December 31, 2018			June 30, 2019			December 31, 2018
	(in millions of dollars)
Fixed maturity securities:
Receive fixed functional currency interest, pay fixed foreign currency interest	$	120.7		$	56.2		$	(1.9	)	$	(2.7	)
Long-term Debt	(248.1		)	(244.4		)	1.5			5.1

For the three and six months ended June 30, 2019, $1.6 million and $1.5 million, respectively, of the derivative instruments' gain was excluded from the assessment of hedge effectiveness. For the three and six months ended June 30, 2018, $1.0 million of the derivative instruments' gain was excluded from the assessment of hedge effectiveness. There were no instances wherein we discontinued fair value hedge accounting due to a hedged firm commitment no longer qualifying as a fair value hedge.

Derivatives not Designated as Hedging Instruments

As of June 30, 2019 and December 31, 2018, we held $148.2 million and $173.7 million, respectively, notional amount of receive fixed, pay fixed, foreign currency interest rate swaps. These derivatives are not designated as hedges, and as such, changes in fair value related to these derivatives are reported in earnings as a component of net realized investment gain or loss.

As of June 30, 2019 and December 31, 2018, we held $10.9 million and $11.0 million, respectively, notional amount of single name credit default swaps. We entered into these swaps in order to mitigate the credit risk associated with specific securities owned.

We have an embedded derivative in a modified coinsurance arrangement for which we include in our realized investment gains and losses a calculation intended to estimate the value of the option of our reinsurance counterparty to cancel the reinsurance contract with us. However, neither party can unilaterally terminate the reinsurance agreement except in extreme circumstances resulting from regulatory supervision, delinquency proceedings, or other direct regulatory action. Cash settlements or collateral related to this embedded derivative are not required at any time during the reinsurance contract or at termination of the reinsurance contract. There are no credit-related counterparty triggers, and any accumulated embedded derivative gain or loss reduces to zero over time as the reinsured business winds down.

Insurance [Abstract]

Liability for Unpaid Claims and Claims Adjustment Expenses Disclosure

Changes in the liability for unpaid claims and claim adjustment expenses are as follows:

	2019			2018
	(in millions of dollars)
Balance at January 1	$	23,149.0		$	23,222.0
Less Reinsurance Recoverable	2,227.3			2,182.0
Net Balance at January 1	20,921.7			21,040.0
Incurred Related to
Current Year	3,101.9			2,943.0
Prior Years
Interest	545.5			552.1
All Other Incurred	(202.2		)	(230.9		)

Current Year	(973.4		)	(904.3		)
Prior Years	(2,542.1		)	(2,498.4		)
Total Paid	(3,515.5		)	(3,402.7		)
Net Balance at June 30	20,842.9			20,856.8
Plus Reinsurance Recoverable	2,247.7			2,188.4
Balance at June 30	$	23,090.6		$	23,045.2

The majority of the net balances are related to disability claims with long-tail payouts on which interest earned on assets backing liabilities is an integral part of pricing and reserving. Interest accrued on prior year reserves has been calculated on the opening reserve balance less one-half of the period's claim payments relative to prior years at our average reserve discount rate for the respective periods.

"Incurred Related to Prior Years - All Other Incurred" shown in the preceding chart is primarily impacted by the level of claim resolutions in the period relative to the long-term expectations reflected in the reserves. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the life of the block of business and will vary from actual experience in any one period, both favorably and unfavorably.

Reconciliation

A reconciliation of policy and contract benefits and reserves for future policy and contract benefits as reported in our consolidated balance sheets to the liability for unpaid claims and claim adjustment expenses is as follows:

	June 30
	2019		2018
	(in millions of dollars)
Policy and Contract Benefits	$	1,751.4	$	1,625.4
Reserves for Future Policy and Contract Benefits	47,138.3		43,959.4
Total	48,889.7		45,584.8
Less:
Life Reserves for Future Policy and Contract Benefits	8,335.1		8,276.9
Accident and Health Active Life Reserves	12,008.3		10,895.6
Adjustment Related to Unrealized Investment Gains and Losses	5,455.7		3,367.1
Liability for Unpaid Claims and Claim Adjustment Expenses	$	23,090.6	$	23,045.2

The adjustment related to unrealized investment gains and losses reflects the changes that would be necessary to policyholder liabilities if the unrealized investment gains and losses related to the corresponding available-for-sale securities had been realized. Changes in this adjustment are reported as a component of other comprehensive income or loss.

We measure and analyze our segment performance on the basis of "adjusted operating revenue" and "adjusted operating income" or "adjusted operating loss", which differ from total revenue and income before income tax as presented in our consolidated statements of income due to the exclusion of net realized investment gains and losses as specified in the reconciliations below. We believe adjusted operating revenue and adjusted operating income or loss are better performance measures and better indicators of the revenue and profitability and underlying trends in our business. These performance measures are in accordance with GAAP guidance for segment reporting, but they should not be viewed as a substitute for total revenue, income before income tax, or net income. 

Realized investment gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our segments. Our investment focus is on investment income to support our insurance liabilities as opposed to the generation of realized investment gains or losses. Although we may experience realized investment gains or losses which will affect future earnings levels, a long-term focus is necessary to maintain profitability over the life of the business since our underlying business is long-term in nature, and we need to earn the interest rates assumed in calculating our liabilities.

We may at other times exclude certain other items from our discussion of financial ratios and metrics in order to enhance the understanding and comparability of our operational performance and the underlying fundamentals. We exclude these items as we believe them to be infrequent or unusual in nature, but this exclusion is not an indication that similar items may not recur and does not replace net income or net loss as a measure of our overall profitability.

A reconciliation of total revenue to "adjusted operating revenue" and income before income tax to "adjusted operating income" is as follows:

The U.S. qualified and non-qualified defined benefit pension plans comprise the majority of our total benefit obligation and benefit cost. We maintain a separate defined benefit plan for eligible employees in our U.K. operation. The U.S. defined benefit pension plans were closed to new entrants on December 31, 2013, the OPEB plan was closed to new entrants on December 31, 2012, and the U.K. plan was closed to new entrants on December 31, 2002.

Stockholders' Equity and Earnings Per Common Share

Stockholders' Equity and Earnings Per Common Share [Abstract]

Earnings Per Share Disclosure

Earnings Per Common Share

Net income per common share is determined as follows:

	Three Months Ended June 30				Six Months Ended June 30
	2019		2018		2019		2018
	(in millions of dollars, except share data)
Numerator
Net Income	$	281.2	$	285.5	$	562.1	$	559.0
Denominator (000s)
Weighted Average Common Shares - Basic	211,068.7		220,776.7		212,672.8		221,335.7
Dilution for Assumed Exercises of Stock Options and Nonvested Stock Awards	43.9		286.0		88.3		484.5
Weighted Average Common Shares - Assuming Dilution	211,112.6		221,062.7		212,761.1		221,820.2
Net Income Per Common Share
Basic	$	1.33	$	1.29	$	2.64	$	2.53
Assuming Dilution	$	1.33	$	1.29	$	2.64	$	2.52

We use the treasury stock method to account for the effect of outstanding stock options, nonvested restricted stock units, and nonvested performance share units on the computation of diluted earnings per share. Under this method, these potential common shares will each have a dilutive effect, as individually measured, when the average market price of Unum Group common stock during the period exceeds the exercise price of the stock options and the grant price of the nonvested restricted stock units and the nonvested performance share units. The outstanding stock options have exercise prices ranging from $23.35 to $24.25, the nonvested restricted stock units have grant prices ranging from $33.28 to $55.26, and the nonvested performance share units have grant prices ranging from $37.67 to $49.86.

In computing earnings per share assuming dilution, only potential common shares that are dilutive (those that reduce earnings per share) are included. Potential common shares excluded in the computation of diluted earnings per share because the impact would be antidilutive, based on then current market prices, approximated 1.2 million potential common shares for both the three and six months ended June 30, 2019. There were approximately 0.7 million and 0.4 million potential common shares that were antidilutive for the three and six months ended June 30, 2018, respectively.

Stockholders' Equity Disclosure

Common Stock

During the second quarter of 2019, our board of directors authorized the repurchase of up to $750.0 million of Unum Group's outstanding common stock through November 23, 2020. This authorization replaced the previous authorization of $750.0 million that was scheduled to expire on November 24, 2019. The remaining repurchase amount under the new program was $716.2 million at June 30, 2019.

Common stock repurchases, which are accounted for using the cost method and classified as treasury stock until otherwise retired, were as follows:

	Three Months Ended June 30				Six Months Ended June 30
	2019		2018		2019		2018
	(in millions)
Shares Repurchased	2.9		2.5		5.6		4.4
Cost of Shares Repurchased1	$	100.2	$	100.1	$	200.2	$	200.3

¹ Includes commissions of $0.2 million for the three months ended June 30, 2019 and a de minimis amount of commissions for the three months ended June 30, 2018. For the six months ended June 30, 2019 and 2018, these amounts included commissions of $0.2 million, respectively.

Preferred Stock

Unum Group has 25.0 million shares of preferred stock authorized with a par value of $0.10 per share. No preferred stock has been issued to date.

Commitments and Contingent Liabilities

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies Disclosure

Commitments and Contingent Liabilities

Contingent Liabilities

We are a defendant in a number of litigation matters that have arisen in the normal course of business. Further, state insurance regulatory authorities and other federal and state authorities regularly make inquiries and conduct investigations concerning our compliance with applicable insurance and other laws and regulations. Given the complexity and scope of our litigation and regulatory matters, it is not possible to predict the ultimate outcome of all pending investigations or legal proceedings or provide reasonable estimates of potential losses, except if noted in connection with specific matters.

In some of these matters, no specified amount is sought. In others, very large or indeterminate amounts, including punitive and treble damages, are asserted. There is a wide variation of pleading practice permitted in the United States courts with respect to requests for monetary damages, including some courts in which no specified amount is required and others which allow the plaintiff to state only that the amount sought is sufficient to invoke the jurisdiction of that court. Further, some jurisdictions permit plaintiffs to allege damages well in excess of reasonably possible verdicts. Based on our extensive experience and that of others in the industry with respect to litigating or resolving claims through settlement over an extended period of time, we believe that the monetary damages asserted in a lawsuit or claim bear little relation to the merits of the case, or the likely disposition value. Therefore, the specific monetary relief sought is not stated.

Unless indicated otherwise in the descriptions below, reserves have not been established for litigation and contingencies. An estimated loss is accrued when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

Claims Handling Matters

We and our insurance subsidiaries, in the ordinary course of our business, are engaged in claim litigation where disputes arise as a result of a denial or termination of benefits. Most typically these lawsuits are filed on behalf of a single claimant or policyholder, and in some of these individual actions punitive damages are sought, such as claims alleging bad faith in the handling of insurance claims. For our general claim litigation, we maintain reserves based on experience to satisfy judgments and settlements in the normal course. We expect that the ultimate liability, if any, with respect to general claim litigation, after consideration of the reserves maintained, will not be material to our consolidated financial condition. Nevertheless, given the inherent unpredictability of litigation, it is possible that an adverse outcome in certain claim litigation involving punitive damages could, from time to time, have a material adverse effect on our consolidated results of operations in a period, depending on the results of operations for the particular period.

From time to time class action allegations are pursued where the claimant or policyholder purports to represent a larger number of individuals who are similarly situated. Since each insurance claim is evaluated based on its own merits, there is rarely a single act or series of actions which can properly be addressed by a class action. Nevertheless, we monitor these cases closely and defend ourselves appropriately where these allegations are made.

Miscellaneous Matters

Similar to other insurers, we were the subject of an examination by a third party acting on behalf of a number of state treasurers concerning our compliance with the unclaimed property laws of the participating states. We cooperated fully with this examination and in the fourth quarter of 2017, we started the process to reach a Global Resolution Agreement with the third party regarding settlement of the examination, which we finalized in January of 2018. Under the terms of the agreement, the third party acting on behalf of the signatory states compared insured data to the Social Security Administration's Death Master File to identify deceased insureds and contract holders where a valid claim has not been made. During the fourth quarter of 2017, we established reserves which reflect our estimate of the liability expected to be paid as we execute on the terms of the settlement. We also are cooperating with a Delaware Market Conduct examination involving the same issue, which is currently inactive. The legal and regulatory environment around unclaimed death benefits continues to evolve. It is possible that the current settlement and/or similar investigations by other state jurisdictions may result in payments to beneficiaries, the payment of abandoned funds under state law, and/or administrative penalties, the total of which may be in excess of the reserves established.

In 2009, a Pennsylvania-based insurance company and its affiliates were ordered into rehabilitation, and the Pennsylvania Insurance Commissioner, who was appointed as the Rehabilitator, filed petitions for liquidation with the Commonwealth Court of Pennsylvania. Under Pennsylvania law, payment of covered claims and other related insurance obligations are provided, within prescribed limits, by state guaranty associations. These guaranty associations assess fees to meet these obligations on insurance companies that sell insurance within the state, which are generally based on a company's pro rata portion of average premiums written or received for several years prior to the insolvency. In March 2017, a formal order of liquidation was issued, and as such, we were subject to an assessment by those guaranty associations that are responsible for policyholder claims, and accordingly accrued, in the first quarter of 2017, an estimated loss contingency. We continue to submit payment to satisfy this assessment as requests for payment are received from the guaranty associations.

Securities Class Actions: Three alleged securities class action lawsuits have been filed against Unum Group and individual defendants as follows:

• On June 13, 2018, an alleged securities class action lawsuit entitled Cynthia Pittman v. Unum Group, Richard McKenney, John McGarry, and Daniel Waxenberg was filed in the United States District Court for the Eastern District of Tennessee. The plaintiff seeks to represent purchasers of Unum Group publicly traded securities between January 31, 2018 and May 2, 2018. The plaintiff alleges the Company caused its shares to trade at artificially high levels by failing to disclose information about the rate of long-term care policy terminations and long-term care claim incidence resulting in misleading statements about capital management plans and long-term care reserves. The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder and seeks compensatory damages in an amount to be proven at trial. The Company strongly denies these allegations and will vigorously defend the litigation.

• On July 13, 2018, an alleged securities class action lawsuit entitled Scott Cunningham v. Unum Group, Richard McKenney, John McGarry, and Daniel Waxenberg was filed in the United States District Court for the Eastern District of Tennessee. The allegations, class period, and damages claimed mirror those in the Pittman matter. The Company strongly denies these allegations and will vigorously defend the litigation.

• On July 25, 2018, an alleged securities class action lawsuit entitled City of Taylor Police and Fire Retirement System v. Unum Group, Richard McKenney, John McGarry, Steve Zabel, and Daniel Waxenberg was filed in the United States District Court for the Eastern District of Tennessee. The plaintiff seeks to represent purchasers of Unum Group publicly traded securities between October 27, 2016 and May 1, 2018. The allegations and damages claimed mirror those in the Pittman matter. The Company strongly denies these allegations and will vigorously defend the litigation.

On November 9, 2018, the court consolidated the Pittman, Cunningham, and City of Taylor Police and Fire Retirement System cases into one matter entitled In re Unum Group Securities Litigation, appointed a lead plaintiff and lead plaintiff’s counsel, and directed the plaintiff to file a consolidated amended complaint. On January 15, 2019, the plaintiff filed a consolidated amended complaint asserting claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder and seeks compensatory damages in an amount to be proven at trial as well as costs, expenses, and attorney’s fees. On March 18, 2019, the Company filed a motion to dismiss the consolidated amended complaint.

These lawsuits are in a very preliminary stage, the outcome is uncertain, and the Company is unable to estimate a range of reasonably possible losses. Reserves have not been established for these matters. Although we believe these claims lack merit, an adverse outcome in one or more of these actions could, depending on the nature, scope, and amount of the ruling, materially adversely affect our consolidated results of operations in a period.

Leases [Abstract]

Lessee, Operating Leases

We lease certain buildings and equipment under various noncancelable operating lease agreements. In addition, we have sub-lease agreements on a limited number of our building lease agreements. The majority of our building leases and sub-leases expire within a five to ten year period and we generally have the option to renew at the end of the lease term for an additional five to ten year period at the fair rental value at the time of renewal. The majority of our equipment leases expire within a one to three year period and we generally have the option to renew at the end of the lease term for an additional one to three year period at the fair rental value at the time of renewal.

We do not have any lease agreements or sub-lease agreements that contain variable lease payments. In addition, we do not have lease agreements or sub-lease agreements that contain residual value guarantees or impose any restrictions or covenants with the lessors.

We determine if an arrangement is a lease at inception through a formal process that evaluates our right to control the use of an identified asset for a period of time in exchange for consideration. We account for the lease and non-lease components of our building leases separately and have elected to use the available practical expedient to account for the lease and non-lease components of our equipment leases as a single component. All of our leases are classified as operating, none of which are classified as short-term leases. For each operating lease, we calculate a lease liability at commencement date based on the present value of lease payments over the lease term and a corresponding right-of-use (ROU) asset, adjusted for lease incentives.

ROU assets represent our right to use an underlying asset for a specified lease term and are included in other assets in our consolidated balance sheet. Lease liabilities represent the present value of lease payments that we are obligated to pay arising from a lease and are included in other liabilities in our consolidated balance sheet. We consider the likelihood of renewal in determining the lease terms for the calculation of the ROU asset and lease liability. As most of our leases do not provide an implicit rate of interest, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate of interest when readily determinable.

Operating lease cost is calculated on a straight-line basis over the lease term and is included in other expenses in our consolidated statement of income. We amortize the ROU asset over the lease term on a pattern determined by the difference between the straight-line lease liability expense and the accretion of the imputed interest calculated on the lease liability.

Operating lease information is as follows:

Debt Disclosure [Abstract]

Debt Disclosure

Debt

During the six months ended June 30, 2019, we made principal payments of $30.0 million on our senior secured non-recourse notes issued by Northwind Holdings, LLC.

In June 2019, we issued $400.0 million of 4.00% senior notes due 2029. The notes are callable at or above par and rank equally in the right of payment with all of our other unsecured and unsubordinated debt.

In April 2019, we amended the terms of our existing five-year unsecured revolving credit facility, increasing it from $400.0 million to $500.0 million. The credit facility, which was previously set to expire in 2021, was extended through April 2024. Under the terms of the amended agreement, we may request that the credit facility be increased up to $700.0 million, up from the previous amount of $600.0 million. We also may request, on up to two occasions, that the lenders' commitment termination dates be extended by one year. The credit facility provides for the issuance of letters of credit subject to certain terms and limitations. At June 30, 2019, letters of credit totaling $2.0 million had been issued from the credit facility, but there were no borrowed amounts outstanding.

Also in April 2019, we separately entered into a three-year, $100.0 million unsecured revolving credit facility with a different syndicate of lenders, which is set to expire in April 2022. Under the terms of the agreement, we may request that the credit facility be increased up to $140.0 million. We also may request that the lenders' commitment termination dates be extended by

one year. The credit facility provides for the issuance of letters of credit subject to certain terms and limitations. At June 30, 2019, there have been no letters of credit issued from the credit facility and there were no borrowed amounts outstanding.

Borrowings under the credit facilities are for general corporate uses and are subject to financial covenants, negative covenants, and events of default that are customary. The two primary financial covenants include limitations based on our leverage ratio and consolidated net worth. We are also subject to covenants that limit subsidiary indebtedness. The credit facilities provide for borrowings at an interest rate based either on the prime rate or LIBOR.

Realized and unrealized investment gains and losses presented in the preceding tables represent gains and losses only for the time during which the applicable financial instruments were classified as Level 3. The transfers between levels resulted primarily from a change in observability of three inputs used to determine fair values of the securities transferred: (1) transactional data for new issuance and secondary trades, (2) broker/dealer quotes and pricing, primarily related to changes in the level of activity in the market and whether the market was considered orderly, and (3) comparable bond metrics from which to perform an analysis. For fair value measurements of financial instruments that were transferred either into or out of Level 3, we reflect the transfers using the fair value at the beginning of the period. We believe this allows for greater transparency, as all changes in fair value that arise during the reporting period of the transfer are disclosed as a component of our Level 3 reconciliation. Gains (losses) which are included in earnings and are attributable to the change in fair value of assets or liabilities valued using significant unobservable inputs and still held at period end were $(0.8) million and $4.7 million for the three and six months ended June 30, 2019, respectively, and $(2.3) million and $(4.0) million for the three and six months ended June 30, 2018, respectively. These amounts relate entirely to the change in fair value of an embedded derivative in a modified coinsurance arrangement and are reported as a component of realized investment gains and losses.

Quantitative Information Regarding Significant Unobservable Inputs

The table below provides quantitative information regarding the significant unobservable inputs used in Level 3 fair value measurements derived from internal models.
