Unum Group Reports Second Quarter 2013 Results

CHATTANOOGA, Tenn.(August 5, 2013) - Unum Group (NYSE: UNM) today reported net income of $218.6 million ($0.82 per diluted common share) for the second quarter of 2013, compared to net income of $216.4 million ($0.76 per diluted common share) for the second quarter of 2012.

Included in the results for the second quarter of 2013 is a net after-tax gain of $0.1 million (less than a penny per diluted common share) resulting from the combined impact of realized investment gains and losses on the Company's investment portfolio and the amortization of prior period actuarial losses on the Company's pension plans. This compares to a net after-tax loss of $8.9 million ($0.03 per diluted common share) in the second quarter of 2012. Adjusting for these items, after-tax operating income was $218.5 million ($0.82 per diluted common share) in the second quarter of 2013, compared to $225.3 million ($0.79 per diluted common share) in the second quarter of 2012.

“Driven primarily by very good risk results across our core business lines, operating performance in the second quarter remained strong with solid returns in our core business segments.  I am also encouraged by the performance we are seeing in those areas which had been operating below our expectations, especially in our Unum UK segment where the repricing actions we are taking are beginning to emerge in our results,” said Thomas R. Watjen, president and chief executive officer. “While sales growth continues to be a challenge in the US, we remain committed to maintaining the pricing and underwriting discipline that has served us so well in the past. Although the environment is expected to gradually improve, it still remains challenging, and we will continue to take the actions necessary to maintain the momentum we have worked so hard to create at the Company.”

RESULTS BY SEGMENT

Unum US Segment

Unum US reported operating income of $214.0 million in the second quarter of 2013, an increase of 0.6 percent from $212.7 million in the second quarter of 2012. Premium income for the segment increased 1.5 percent to $1,131.5 million in the second quarter of 2013, compared to premium income of $1,115.0 million in the second quarter of 2012.

Within the Unum US operating segment, the group disability line of business reported a 3.7 percent increase in operating income, with $73.0 million in the second quarter of 2013 compared to $70.4 million in the second quarter of 2012. Premium income in group disability increased 1.5 percent to $523.9 million in the second quarter of 2013, compared to $516.0 million in the second quarter of 2012, as the impact of premium rate increases was partially offset by a decline in premium persistency and lower sales during the quarter. The benefit ratio for the second quarter of 2013 was 83.9 percent, compared to 84.7 percent in the second quarter of 2012. Underlying these results were improved risk results in group short-term disability. Unum US reported less favorable risk results in group long-term disability due primarily to the impact of a 50 basis point decrease in the discount rate during the third quarter of 2012 for new claim incurrals, partially offset by favorable new claim incidence. Group long-term disability sales declined 8.9 percent to $32.8 million in the second quarter of 2013, compared to $36.0 million in the second quarter of 2012. Group short-term disability sales decreased 20.8 percent to $18.7 million in the second quarter of 2013, compared to $23.6 million in the second quarter of 2012. Premium persistency in the group long-term disability line of business was 88.5 percent through the first two quarters of 2013, compared to 91.7 percent through the first two quarters of 2012. Case persistency for this line was 88.3 percent through the first two quarters of 2013, matching the level from the comparable period in 2012. Premium persistency in the group short-term disability line of business was 88.5 percent through the first six months of 2013, compared to 89.8 percent for the same period of 2012. Case persistency for the short-term disability line was 87.6 percent through the first six months of 2013, compared to 87.8 percent through the first six months of 2012.

The group life and accidental death and dismemberment line of business reported operating income of $57.3 million in the second quarter of 2013, in line with the results from the second quarter of 2012, as growth in premium income and favorable risk experience were offset by slightly higher operating expenses and lower net investment income. Premium income for this line of business increased 3.4 percent to $333.8 million in the second quarter of 2013, compared to $322.9 million in the second quarter of 2012, reflecting growth from prior year sales and rate increases, partially offset by lower premium persistency. The benefit ratio in the second quarter of 2013 was 71.1 percent, compared to 71.9 percent in the second quarter of 2012, reflecting more favorable experience related to the waiver of group life premium benefit. Sales of group life and accidental death and dismemberment products decreased 27.1 percent in the second quarter of 2013 to $36.5 million, compared to $50.1 million in the second quarter of 2012. Premium persistency in the group life line of business

UNUM IS A REGISTERED TRADEMARK AND MARKETING BRAND OF UNUM GROUP AND ITS INSURING SUBSIDIARIES. 2

was 89.1 percent through the first six months of 2013, compared to 91.6 percent for the same period of 2012. Case persistency in the group life line of business through the first six months of 2013, at 88.3 percent, was up slightly from 88.1 percent through the first six months of 2012.

The supplemental and voluntary line of business reported a 1.5 percent decrease in operating income to $83.7 million in the second quarter of 2013, compared to $85.0 million in the second quarter of 2012. Premium income for supplemental and voluntary decreased 0.8 percent to $273.8 million in the second quarter of 2013, compared to $276.1 million in the second quarter of 2012. This decrease results from a reinsurance agreement entered into during the second quarter of 2013 to cede a small block of individual disability - recently issued business, partially offset by increased premium income in the voluntary benefits business. The interest adjusted loss ratio for the individual disability - recently issued product line in the second quarter of 2013 rose to 31.3 percent from 30.8 percent in the second quarter of 2012, with stable claim experience but slightly higher reserve increases related to claim inventories as compared to the second quarter of 2012. The benefit ratio for voluntary benefits, at 48.2 percent in the second quarter of 2013, was up from 46.8 percent in the second quarter of 2012. Favorably impacting the benefit ratio for the second quarter of 2012 was the release of active life reserves associated with a voluntary benefits large case customer who terminated the existing individual contracts and bought voluntary group coverage during the second quarter of 2012. Relative to the second quarter of 2012, sales in the voluntary benefits line of business decreased 9.3 percent in the second quarter of 2013 to $33.2 million. Sales in the individual disability - recently issued line of business decreased 33.3 percent in the second quarter of 2013 to $10.2 million. Premium persistency in the individual disability - recently issued product line was 90.7 percent through the first six months of 2013, compared to 90.3 percent for the same period of 2012. Premium persistency in the voluntary benefits product line was 76.5 percent through the first six months of 2013, compared to 79.4 percent through the first six months of 2012.

Unum UK Segment

Unum UK reported operating income of $33.5 million in the second quarter of 2013, an increase of 11.7 percent from $30.0 million in the second quarter of 2012. In local currency, operating income for the second quarter of 2013 increased 14.1 percent, to £21.8 million from £19.1 million in the second quarter of 2012.

Premium income decreased 20.6 percent to $137.6 million in the second quarter of 2013, compared to $173.2 million in the second quarter of 2012, due primarily to reinsurance agreements entered into in the first quarter 2013 to cede an additional portion of the group life business. In local currency, premium income decreased 18.1 percent to £89.6 million in the second quarter of 2013, compared to £109.4 million in the second quarter of 2012. The benefit ratio in the second quarter of 2013 was 84.2 percent, compared to 85.4 percent in the comparable quarter in 2012. The lower benefit ratio in the second quarter of 2013 reflects favorable risk experience in the group long-term disability line resulting from favorable claim incidence and claim recovery rates.

UNUM IS A REGISTERED TRADEMARK AND MARKETING BRAND OF UNUM GROUP AND ITS INSURING SUBSIDIARIES. 3

Persistency in the group long-term disability line of business was 82.0 percent through the first six months of 2013, compared to 84.1 percent through the first six months of 2012. Persistency in the group life line of business was 74.0 percent through the first six months of 2013, compared to 82.4 percent through the comparable period of 2012. Sales decreased 9.6 percent to $21.7 million in the second quarter of 2013, compared to $24.0 million in the second quarter of 2012. In local currency, sales for the second quarter of 2013 decreased 7.2 percent to £14.2 million, compared to £15.3 million in the second quarter of 2012, reflecting a significant decline in group life sales due to rate increases and scaling back sales in certain market sectors, partially offset by stronger group long-term disability sales.

Colonial Life Segment

Colonial Life reported a 5.2 percent increase in operating income to $71.1 million in the second quarter of 2013, compared to $67.6 million in the second quarter of 2012.

Premium income for the second quarter of 2013 increased 3.7 percent to $307.9 million, compared to $296.9 million in the second quarter of 2012, driven by continued favorable persistency. The benefit ratio in the second quarter of 2013 was 52.1 percent, down from 52.5 percent in the second quarter of 2012, as less favorable incurred claims experience in the cancer and critical illness product line was more than offset by improved risk experience in the accident, sickness, and disability product line as well as the life product line.

Sales decreased 2.0 percent to $84.1 million in the second quarter of 2013 from $85.8 million in the second quarter of 2012, as a decrease in commercial sector sales in the second quarter of 2013 was only partially offset by an increase in public sector sales in the second quarter of 2013 relative to the comparable period in 2012.

Closed Block Segment

The Closed Block segment reported operating income of $29.6 million in the second quarter of 2013, compared to $25.7 million in the second quarter of 2012.

Premium income for this segment declined 4.0 percent in the second quarter of 2013 compared to the comparable year-ago quarter, primarily due to the expected run-off of the individual disability block of business. Net investment income was higher in the second quarter of 2013 relative to the same period of last year due primarily to an increase in assets supporting the long-term care block of business. The interest adjusted loss ratio for the individual disability line of business was 82.7 percent in the second quarter of 2013, in-line with the second quarter of 2012. The interest adjusted loss ratio for the long-term care line of business rose to 90.1 percent in the second quarter of 2013 from 87.8 percent in the second quarter of 2012 due to an increase in the level of submitted claims and slightly higher group long-term care persistency driving higher active life reserve changes.

Corporate Segment

The Corporate segment reported an operating loss of $37.1 million in the second quarter of 2013, compared to a loss of $25.9 million in the second quarter of 2012. The higher operating loss in the second

quarter of 2013 was driven primarily by lower net investment income and slightly higher interest expense due to the issuance of $250 million of debt during the third quarter of 2012. Net investment income was lower in the second quarter of 2013 compared to the second quarter of 2012 due to lower yielding assets and a decrease in investment income attributable to tax credit partnerships. However, the negative impact on net investment income from the tax credit partnerships was offset by a lower income tax rate due to the tax benefits recognized as a result of these investments.

The Company's average number of shares outstanding, assuming dilution, was 266.7 million for the second quarter of 2013, compared to 283.7 million for the second quarter of 2012.

NON-GAAP FINANCIAL MEASURES

The Company analyzes its 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 measures included in this release are:

• Operating income or loss, which is net income or loss, excluding net realized investment gains or losses and non-operating retirement-related gains or losses and, when reported by segment, is before tax.

• Operating earnings per share, which is after-tax operating income per diluted common share.

For a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures, refer to the tables in the Financial Highlights section below.

UNUM IS A REGISTERED TRADEMARK AND MARKETING BRAND OF UNUM GROUP AND ITS INSURING SUBSIDIARIES. 5

The Company believes operating income or loss is a better performance measure and a better indicator of the profitability and underlying trends in its business. Realized investment gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of the Company's segments. The Company's investment focus is on investment income to support its insurance liabilities as opposed to the generation of realized investment gains or losses. Although the Company 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 the Company's underlying business is long-term in nature, and the Company needs to earn the interest rates assumed in calculating its liabilities. Certain components of the net periodic benefit cost for the Company's pensions and other postretirement benefit plans, namely the amortization of prior period actuarial gains or losses, are primarily driven by market performance and are not indicative of the operational results of the Company's businesses. The Company believes that excluding the amortization of prior period gains or losses from operating income or loss by segment provides investors with additional information for comparison and analysis of operating results. Although the Company manages its non-operating retirement-related gains or losses separately from the operational performance of its business, these gains or losses impact the overall profitability of the Company and will increase or decrease over time, depending on market conditions and the resulting impact on the actuarial gains or losses in the Company's pensions and other postretirement benefit plans.

2013

In June 2013, we announced plan amendments which freeze participation and benefit accruals in our U.S. qualified and non-qualified defined benefit pension plans, effective December 31, 2013. Because the amendments eliminate all future service accruals subsequent to December 31, 2013 for active employees in these plans, we were required to remeasure the benefit obligations of our U.S. plans during the second quarter of 2013, which decreased our net pension liability by $327.4 million, with a corresponding increase in other comprehensive income, less applicable income tax of $114.6 million. The decrease in the net pension liability resulted primarily from the curtailment of benefits under the plan amendments as well as an increase in the discount rate assumption used to remeasure the benefit obligations.

2012

Effective January 1, 2012, we adopted an accounting standards update regarding the capitalization of costs associated with the acquisition of insurance contracts and applied the amendments retrospectively. Operating income by segment has been adjusted to reflect our retrospective adoption.

We previously allocated the amortization of prior period actuarial gains or losses, the component of the net periodic benefit costs for our pensions and other postretirement benefit plans which we consider to be non-operating, to our Corporate segment. During the first quarter of 2012, we determined that we would modify our segment reporting. Effective January 1, 2012, the amortization of prior period actuarial gains or losses was no longer included in operating income or operating loss by segment. Prior period segment results for our Corporate segment have been adjusted to conform to current year reporting.

2011

Year ended December 31, 2011 results included the following:

• A deferred acquisition costs impairment charge of $196.0 million before tax and $127.5 million after tax related to our long-term care closed block business.

• A reserve charge of $573.6 million before tax and $372.8 million after tax related to our long-term care closed block business.

• A reserve charge of $183.5 million before tax and $119.3 million after tax related to our individual disability closed block business.

• An income tax benefit of $41.3 million due to a final settlement with the Internal Revenue Service with respect to our appeal of audit adjustments for the tax years 1996 to 2004.

• An income tax charge of $18.6 million related to the repatriation of £150.0 million of dividends from our U.K. subsidiaries.

2010

Year ended December 31, 2010 results included a tax charge of $10.2 million to reflect the impact of a tax law change.

Notes to Statistical Supplement

Non-GAAP Financial Measures

We analyze our Company's performance using non-GAAP financial measures which exclude certain items and the related tax thereon from net income. We believe operating revenue, which excludes realized investment gains or losses, and operating income or loss, which excludes realized investment gains or losses and non-operating retirement-related gains or losses, both of which are recurring, are better performance measures and better indicators of the profitability and underlying trends in our business. Both realized investment gains or losses and non-operating retirement-related gains or losses depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our Company. The exclusion of these items from our performance does not replace revenue and net income or net loss as measures of our overall profitability. We also believe book value per common share excluding the components of Accumulated Other Comprehensive Income, certain of which tend to fluctuate depending on market conditions and general economic trends, is an important measure.

2013 Significant Transactions and Events

Financing

In January 2013, we purchased and retired the outstanding principal of $62.5 million on our senior secured notes issued by Tailwind Holdings, LLC, resulting in a before-tax gain of $4.0 million.

Share Repurchase Program

During the first six months of 2013, we repurchased 7.3 million shares at a cost of $193.5 million, including commissions, under the July 2012 share repurchase program. The dollar value of shares remaining under the repurchase program was $356.6 million at June 30, 2013.

Retirement Benefit Plan Changes

In June 2013, we announced plan amendments which freeze participation and benefit accruals in our U.S. qualified and non-qualified defined benefit pension plans, effective December 31, 2013. Because the amendments eliminate all future service accruals subsequent to December 31, 2013 for active employees in these plans, we were required to remeasure the benefit obligations of our U.S. plans during the second quarter of 2013, which decreased our net pension liability by $327.4 million, with a corresponding increase in other comprehensive income, less applicable income tax of $114.6 million.

As a result of these plan amendments, during the second quarter of 2013 we recognized a $0.7 million curtailment loss, with a corresponding reduction in the prior service cost included in accumulated other comprehensive income and associated with years of service no longer expected to be rendered. In addition, because all participants in the U.S. plans are considered inactive as a result of these amendments, we are required to amortize the net actuarial loss for these plans over the average remaining life expectancy of the plan participants, which is approximately 30 years. The net actuarial loss was previously amortized over the average future working life of pension plan participants, or approximately 11 years.

In June 2013, we also communicated plans to amend the defined benefit pension plan for employees in our U.K. operation to freeze participation and benefit accruals effective December 31, 2013. Consistent with U.K. regulatory requirements, this communication initiated a formal 60 day consultation process with U.K. plan participants. If approved, we will remeasure the benefit obligation for our U.K. operation's plan and will record the effect of the remeasurement in the third quarter of 2013.

The unrecognized net actuarial loss and prior service cost included in accumulated other comprehensive income and expected to be amortized and included in net periodic pension cost during 2013 is approximately $33.3 million before tax and $21.9 million after tax. These amounts may change if the benefit obligation for our U.K. operation's plan is remeasured during the third quarter of 2013. The quarterly amortization of our net actuarial loss will be approximately $2.7 million before tax during the remainder of 2013.

2012 Significant Transactions and Events

Accounting Standards Codification (ASC) 944 "Financial Services - Insurance”

In October 2010, the Financial Accounting Standards Board (FASB) issued an update to address the diversity in practice regarding the interpretation of which costs relating to the acquisition of new or renewal insurance contracts qualify as deferred acquisition costs.  The amendments in the update require that only incremental direct costs associated with the successful acquisition of a new or renewal insurance contract can be capitalized. All other costs are to be expensed as incurred. We adopted this update effective January 1, 2012 and applied the amendments retrospectively.

Financing

In August 2012, we issued $250.0 million of unsecured senior notes in a public offering. These notes, due in 2042, bear interest at a fixed rate of 5.75% and are payable semi-annually. The notes are callable at or above par and rank equally in right of payment with all of our other unsecured and unsubordinated debt.

Share Repurchase Program

In July 2012, our board of directors authorized a $750.0 million share repurchase program with an expiration date of January 2014. This program superseded and replaced the February 2011 $1.0 billion share repurchase program. During 2012, we repurchased 23.6 million shares on the open market at a cost of $500.6 million, including commissions of $0.6 million.

2011 Significant Transactions and Events

Long-term Care Strategic Review

Following a comprehensive and strategic review of our long-term care business, in February 2012 we announced that we would discontinue selling group long-term care. We discontinued selling individual long-term care during 2009. Because both group and individual long-term care are considered closed blocks of business, effective December 31, 2011, we reclassified our long-term care products from the Unum US segment to the Closed Block segment.  We also reclassified our other insurance products not actively marketed, including individual life and corporate-owned life insurance, reinsurance pools and management operations, group pension, health insurance, and individual annuities, which were previously reported in the Corporate and Other segment to the Closed Block segment. The inclusion of all closed blocks of business into one operating segment aligns with our reporting and monitoring of our closed blocks of business within a discrete segment and is consistent with our separation of these blocks of business from the lines of business which actively market new products.  Prior period segment results have been restated to reflect these changes in our reporting classifications.

As part of the strategic review, and as is typical in the fourth quarter of each year, we analyzed our reserve assumptions for long-term care in conjunction with our annual loss recognition testing. We generally perform loss recognition tests on our deferred acquisition costs and policy reserves in the fourth quarter of each year, but more frequently if appropriate, using best estimate assumptions as of the date of the test. Included in the analysis was a review of our reserve discount rate assumptions and mortality and morbidity assumptions. Our analysis of reserve discount rate assumptions considered the significant decline in long-term interest rates which occurred late in the third quarter of 2011 due to the European Union debt crisis and the Federal Reserve Board's actions, including the announcement of "Operation Twist." We also considered an updated industry study for long-term care experience which was made available mid-year 2011 from the Society of Actuaries. Our analysis of this study, which was completed during the fourth quarter of 2011, showed that lower termination rates than we had previously assumed were beginning to emerge in industry and in our own company experience. Based on our analysis, as of December 31, 2011 we lowered the discount rate assumption to reflect the low interest rate environment and our expectation of future investment portfolio yield rates. We also changed our mortality assumptions to reflect emerging experience due to an increase in life expectancies which increases the ultimate number of people who will utilize long-term care benefits and also lengthens the amount of time a claimant receives long-term care benefits. We changed our morbidity assumptions to reflect emerging industry experience as well as our own company experience. While our morbidity experience is still emerging

(continued on next page) 15. 1

and is not fully credible, we modified our assumptions to align more closely with the recently published industry study. Using our revised best estimate assumptions, as of December 31, 2011 we determined that deferred acquisition costs of $196.0 million, as adjusted for the January 1, 2012 retrospective adoption of the accounting standards update related to deferred acquisition costs, were not recoverable and that our policy and claim reserves should be increased by $573.6 million to reflect our current estimate of future benefit obligations. These charges decreased our 2011 net income by $500.3 million. The increase in reserves represented a 10.5 percent increase in long-term care policy and claim reserves as of December 31, 2011, which equaled $5.4 billion subsequent to the charge. 

Claim Reserve Increase for Individual Disability Closed Block Business

Claim reserves supporting our individual disability closed block of business are calculated using assumptions based on actual experience believed to be currently appropriate. Claim reserves are subject to revision as current claim experience emerges and alters our view of future expectations. Claim resolution rates, which measure the resolution of claims from recovery, deaths, settlements, and benefit expirations, are very sensitive to operational and environmental changes 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. We are now able, with a higher degree of confidence, to assess our own experience for older ages in our long duration lifetime claim block as our data has become credible. There is very little industry experience for lifetime disability benefits, as our insurance companies were the primary disability companies in the insurance industry at the time lifetime disability benefits were offered. These benefits were offered during the 1980s and 1990s, recent enough such that claimants are just reaching the older ages and providing us with data to build our claim experience base. Emerging experience indicates a longer life expectancy for our older age, longer duration disabled claimants, which lengthens the time a claimant receives disability benefits. As a result of this experience, as of December 31, 2011 we adjusted our mortality assumption within our claim resolution rate assumption and, as a result, increased our claim reserves for our individual disability closed block of business by $183.5 million and decreased net income by $119.3 million. The increase in reserves represented a 1.5 percent increase in individual disability policy and claim reserves as of December 31, 2011, which equaled $11.9 billion subsequent to the charge. 

Share Repurchase Program

In February 2011, our board of directors authorized the repurchase of up to $1.0 billion of Unum Group's common stock, in addition to the amount that remained to be repurchased under the May 2010 $500.0 million authorization. The $1.0 billion share repurchase program had an expiration date of August 2012.

During February 2011, we repurchased 7.1 million shares, at a cost of $200.0 million, using an accelerated repurchase agreement with a financial counterparty. Under the terms of the repurchase agreement, we received a price adjustment based on the volume weighted average price of our common stock during the term of the agreement. The price adjustment resulted in the delivery to us of 0.6 million additional shares. In total, we repurchased 7.7 million shares of our common stock under this agreement, which completed the May 2010 $500.0 million repurchase authorization and initiated the $1.0 billion repurchase program.

In addition to these repurchases, during 2011, we repurchased an additional 17.7 million shares on the open market at a cost of $419.9 million for a total repurchase of 25.4 million shares. Pursuant to these repurchase programs, we retired 7.7 million shares during 2011. All other repurchased shares were classified as treasury stock and accounted for using the cost method.

Income Tax

Our income tax for 2011 includes a reduction in federal income taxes of $41.3 million due to a final settlement with the IRS with respect to our appeal of audit adjustments for the tax years 1996 to 2004. Our income tax for 2011 was unfavorably impacted by an $18.6 million tax charge related to the repatriation of £150.0 million of dividends from our U.K. subsidiaries.

Financing

During 2011, the remaining $225.1 million of our 7.625% senior notes due March 2011 matured.

2010 Significant Transactions and Events

Share Repurchase Program

InMay 2010, our board of directors authorized the repurchase of up to $500.0 million of Unum Group's common stock. During 2010, we repurchased 16.4 million shares, at a cost of $356.0 million under this share repurchase program.

Financing

In 2010, we issued $400.0 million of unsecured senior notes in a public offering.  These notes, due in 2020, bear interest at a fixed rate of 5.625% and are payable semi-annually. We also purchased and retired $10.0 million of our 7.08% medium-term notes due 2024.

Tax Law Change

In March 2010, the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 were signed into law.  Among other things, the new legislation reduced the tax benefits available to an employer that receives a postretirement prescription drug coverage subsidy from the federal government under the Medicare Prescription Drug, Improvement and Modernization Act of 2003.  Under the new legislation, to the extent our future postretirement prescription drug coverage expenses are reimbursed under the subsidy program, the expenses covered by the subsidy will no longer be tax deductible after 2012.  Employers that receive the subsidy must recognize the deferred tax effects relating to the future postretirement prescription drug coverage in the period the legislation was enacted.  Our income tax expense for 2010 included a non-cash tax charge of $10.2 million to reflect the impact of the tax law change.
