The Hartford (NYSE: HIG) today announced financial results for the third quarter ended Sept. 30, 2021. In the quarter, The Hartford earned $476 million in net income available to common stockholders, or $1.36 per diluted share, and core earnings* of $442 million, or $1.26 per diluted share. Reported results included catastrophe (CAT) losses of $300 million, before tax, Property & Casualty (P&C) unfavorable prior accident year reserve development (PYD) of $90 million, before tax, and excess mortality losses in Group Benefits of $212 million, before tax.

Improving operating efficiencies and a lower expense ratio from Hartford Next, the company’s operational transformation and cost reduction program, have benefited results. The program delivered $306 million in pre-tax expense savings in the nine months ended Sept. 30, 2021, compared with the corresponding period in 2019. We continue to expect full year pre-tax savings of approximately $540 million in 2022 and $625 million in 2023.

“Our outstanding underwriting capabilities and ability to consistently execute on our strategic initiatives become increasingly evident with each quarterly earnings report. Strong underlying results and excellent investment returns offset the impact of higher catastrophe losses and an increase in pandemic related excess mortality, resulting in a trailing 12-month core earnings ROE of 12.5%,” said Chairman and CEO Christopher Swift.

President, Doug Elliot said, “Our P&C underlying results were excellent, driven by strong earned pricing and underwriting execution. Commercial Lines delivered a second consecutive quarter of double-digit top line growth led by strong new business and retention. Commercial Lines renewal written pricing, excluding workers’ compensation, was 8.1%. In Personal Lines, we continued the rollout of our new auto and home product, now available in seven states."

Swift said, “Our focus remains on optimizing returns. In the first nine months of the year we returned $1.6 billion of capital to shareholders and are pleased to announce a 10% increase in our common dividend and an increase in the share repurchase authorization to $3.0 billion through 2022. With high recurring cash flow and active capital management we are on the path to generate sustainable industry leading returns, deliver on our financial objectives and maximize value creation for all stakeholders.”

CONSOLIDATED RESULTS:

Third quarter 2021 net income available to common stockholders was $476 million, or $1.36 per diluted share, up $23 million, or 5% from third quarter 2020, primarily due to a $158 million, before tax, increase in net investment income, a $99 million, before tax, decrease in restructuring and other costs, a $64 million, before tax, increase in net realized gains and higher earnings from Hartford Funds partially offset by a $148 million, before tax, decrease in P&C underwriting gain*, and a $170 million, before tax, increase in excess mortality losses.

Third quarter 2021 core earnings were $442 million, or $1.26 per diluted share, decreasing 16% from third quarter 2020. The decrease was primarily due to:

• Excess mortality of $212 million, before tax, in group life in third quarter 2021, primarily caused by direct and indirect impacts of the COVID-19 pandemic, compared with $42 million, before tax, in third quarter 2020
• Unfavorable P&C PYD within core earnings of $62 million, before tax, in third quarter 2021, compared with $89 million of net favorable PYD within core earnings in third quarter 2020
• P&C CAY CAT losses of $300 million, before tax, in third quarter 2021, compared with $229 million of CAY CAT losses in third quarter 2020
• Underlying Personal Lines loss ratio* of 64.4% in third quarter 2021, up 8.4 points from 56.0% in third quarter 2020 as the prior year benefited from lower auto claim frequency due to the pandemic
• An increase in insurance operating costs and other expenses in P&C and Group Benefits, primarily driven by higher incentive compensation, technology costs, P&C commissions and claim costs in Group Benefits to handle elevated claim levels resulting from the pandemic, partially offset by lower staffing and other costs due to the Hartford Next program
• An increase in short-term-disability losses as the prior year period benefited from fewer elective procedures during the early stages of the pandemic

Partially offset by:

• An increase in net investment income to $650 million, before tax, from $492 million in third quarter 2020, primarily driven by higher income from limited partnerships and alternative investments (LPs), which were $83 million, before tax, in third quarter 2020 compared with $259 million, before tax, in third quarter 2021, with LP income in third quarter 2021 driven by higher valuations and cash distributions within private equity funds and sales of underlying investments in real estate
• Underlying ex-COVID-19 Commercial Lines loss ratio* of 55.1% in third quarter 2021, down 4.0 points from 59.1% in third quarter 2020 driven by improvement in all three businesses
• Higher Commercial Lines earned premium, including higher audit and endorsement premiums
• A $34 million, before tax, decrease in COVID-19 incurred losses with $3 million of COVID-19 losses in third quarter 2021 compared with $37 million in third quarter 2020
• An $18 million increase in Hartford Funds core earnings largely driven by higher assets under management
• A loss in core earnings from the previously owned equity interest in Talcott Resolution of $21 million, before tax, in third quarter 2020

Sept. 30, 2021 book value per diluted share of $50.53 was mostly flat compared with $50.39 at Dec. 31, 2020, as the effect of share repurchases on diluted shares outstanding was largely offset by a decrease in total stockholders' equity driven by a decline in AOCI.

Book value per diluted share (excluding AOCI) of $49.64 as of Sept. 30, 2021 increased from $47.16 at Dec. 31, 2020, due to net income in excess of share repurchases and common stockholder dividends during the nine months ended September 30, 2021.

Through Sept. 30, 2021, The Hartford returned approximately $1.6 billion to shareholders, consisting of $1.2 billion of share repurchases and $365 million in common stockholder dividends paid.

Third quarter 2021 net income available to common stockholders' ROE (net income ROE) was 12.3% at Sept. 30, 2021.

Core earnings ROE at Sept. 30, 2021 was 12.5%, an increase of 0.2 points from 12.3% in third quarter 2020 due to higher trailing 12-month core earnings partially offset by higher average common stockholders' equity.

BUSINESS RESULTS:

Commercial Lines

Third quarter 2021 net income of $357 million increased from net income of $323 million in third quarter 2020, principally due to higher net investment income and a change from net realized losses to net realized gains, partially offset by a change from an underwriting gain of $92 million in third quarter 2020 to an underwriting loss of $30 million in third quarter 2021.

Commercial Lines core earnings of $344 million in third quarter 2021 decreased by $5 million from third quarter 2020, primarily resulting from:

• Unfavorable PYD within core earnings of $94 million, before tax, in third quarter 2021, compared with $71 million of favorable PYD within core earnings in third quarter 2020. The $94 million of net unfavorable development in third quarter 2021 primarily included $144 million, before tax, of reserve increases for general liability driven by the settlement agreement with BSA announced in September, partially offset by reserve reductions in workers' compensation, package business and bond
• CAY CAT losses of $222 million, before tax, in third quarter 2021, including $164 million from Hurricane Ida, compared with $107 million in third quarter 2020

Partially offset by:

• Improved underlying underwriting gain before COVID-19 losses of $138 million, before tax, or 5.0 points, including a lower CAY ex-COVID-19 loss ratio before CATs of 4.0 points and a lower expense ratio of 0.9 points
• Net investment income of $421 million, before tax, compared with $316 million in third quarter 2020, including higher returns on LP investments
• Higher earned premium, including higher audit and endorsement premiums
• A $34 million, before tax, decrease in COVID-19 incurred losses with $3 million of COVID-19 losses in third quarter 2021 compared with $37 million in third quarter 2020

Combined ratio was 101.2 in third quarter 2021, 5.3 points higher than 95.9 in third quarter 2020, primarily due to a 7.5 point change from favorable to unfavorable PYD and a 4.3 point increase in CAY CAT losses, partially offset by a 6.5 improvement in the underlying combined ratio. The combined ratio included 1.1 points, or $28 million, before tax, of adverse development for Navigators related to 2018 and prior accident years that has been economically ceded to NICO but recorded as a deferred gain, compared with 0.6 points, or $14 million, before tax, of Navigators adverse development recognized in third quarter 2020.

Underlying combined ratio was 87.2, improving 6.5 points from third quarter 2020 with 1.5 points of the improvement driven by lower COVID-19 incurred losses.

Before COVID-19 losses, the underlying combined ratio improved 5.0 points, including:

• A 4.0 point decrease in the underlying loss and loss adjustment expense ratio primarily due to lower loss ratios in Global Specialty, workers' compensation, general liability, and non-catastrophe property
• A 0.9 point decrease in the expense ratio, driven by the effect of earned premium growth, a lower provision for doubtful accounts, and savings from the Hartford Next program, partially offset by higher commissions, incentive compensation and technology costs

The underlying combined ratio in Commercial Lines improved across all three businesses:

• Small Commercial underlying combined ratio of 83.9 improved by 3.8 points from third quarter 2020 driven primarily by a lower CAY loss ratio before CATs and COVID losses in workers’ compensation, lower non-CAT property losses, and, to a lesser extent, a 0.5 point decrease in COVID losses and a 0.5 point decrease in the expense ratio
• Middle & Large Commercial underlying combined ratio of 91.4 improved by 6.3 points from third quarter 2020 primarily due to a lower CAY loss ratio before CATs and COVID losses in workers’ compensation and general liability, a 1.6 point decrease in COVID losses and, to a lesser extent, a 0.3 point decrease in the expense ratio
• Global Specialty underlying combined ratio of 86.9 improved by 11.3 points from third quarter 2020 due to a lower CAY loss ratio before CATs and COVID losses in several lines, including international, Global Re, U.S. wholesale and U.S. financial lines, a 3.3 point decrease in COVID losses and a 2.0 point decrease in the expense ratio

Third quarter 2021 written premiums of $2.5 billion were up 15% from third quarter 2020, reflecting higher audit and endorsement premiums, an increase in new business across Small Commercial, Middle Market, and Global Specialty, higher policy retention in Middle Market and continued strong renewal written price increases in Middle Market and Global Specialty.

Personal Lines

Net income of $51 million in third quarter 2021 was down $28 million from third quarter 2020 largely driven by a decrease in underwriting gain, partially offset by an increase in net investment income.

Personal Lines core earnings of $48 million declined by $29 million primarily due to a decrease in underlying underwriting gain, partially offset by a $44 million, before tax, decrease in CAY CAT losses. An underlying underwriting gain of $61 million, before tax, in third quarter 2021 compared with a gain of $145 million in third quarter 2020, largely due to a higher CAY loss ratio before CATs in auto and, to a lesser extent, an increase in underwriting expenses and lower earned premiums.

Combined ratio of 98.7 in third quarter 2021 was 5.4 points higher than third quarter 2020, primarily due to higher CAY losses before CATs and an increase in the expense ratio, partially offset by a lower CAY CAT ratio.

Underlying combined ratio of 91.8 was 10.4 points higher than third quarter 2020, primarily due to an increase in CAY losses before CATs in auto and a 2.0 point increase in the expense ratio.

• The auto underlying combined ratio of 99.7 increased 14.8 points from 84.9 in third quarter 2020, primarily due to an increase in auto frequency as a result of increased miles driven and an increase in claim severity as well as a higher expense ratio
• The homeowners underlying combined ratio of 74.6 increased 0.6 points from 74.0 in third quarter 2020, primarily due to a higher expense ratio. The CAY loss ratio before CATs was flat year over year as the effect of earned pricing increases was offset by an increase in both weather and non-weather non-catastrophe losses with an increase in severity partially offset by lower claim frequency. Contributing to the increase in homeowners severity was the effect of higher rebuilding costs and a greater number of large losses

The increase in the expense ratio was driven by higher incentive compensation, technology and direct marketing costs, as well as the effect of a decline in earned premium, partially offset by savings from the Hartford Next program.

Written premiums in third quarter 2021 were $765 million compared with $781 million in third quarter 2020 with the decrease due to:

• A reduction in auto written premiums as non-renewed premium exceeded new business
• A reduction in homeowners as non-renewed premium exceeded new business, partially offset by renewal written price increases in homeowners of 8.1% in third quarter 2021

Group Benefits

Net income and core earnings were $28 million and $19 million, respectively, decreasing from $119 million and $116 million, respectively, in third quarter 2020, largely driven by an increase in excess mortality losses in group life, partially offset by an increase in net investment income.

Fully insured ongoing premiums were up 4%, compared with third quarter 2020, driven by an increase in exposure on existing accounts as our customers emerge from the pandemic as well as strong persistency and sales. Fully insured ongoing sales were $82 million in third quarter 2021, down 39%, as the prior year period had two large account sales.

Loss ratio of 84.7% deteriorated 10.9 points compared with 73.8% in third quarter 2020 driven by an increase in group life and, to a lesser extent, an increase in group disability:

• Total group life loss ratio of 110.9% increased 23.4 points, primarily due to a 28.8 point increase in excess mortality losses. Excess mortality losses were $212 million, before tax, or 35.9 points, in third quarter 2021 compared with $42 million, before tax, or 7.1 points, in third quarter 2020. The $212 million in third quarter 2021 included $233 million related to claims with dates of death in the third quarter, partially offset by a $21 million decrease related to prior quarters, the majority of which related to second quarter 2021
• Total disability loss ratio of 68.4% increased 3.1 points compared with third quarter 2020, due to an increase in short-term disability claim incidence as the prior year benefited from fewer elective procedures during the early stages of the pandemic

Expense ratio of 25.2% increased 0.9 points from third quarter 2020 due to an increase in incentive compensation, technology costs and claim costs to handle elevated claim levels resulting from the pandemic as well as a lower decrease in the allowance for credit losses on premiums receivables, partially offset by lower staffing and other costs as a result of the Hartford Next program and higher earned premiums.

Hartford Funds

Net income and core earnings were $56 million and $58 million, respectively, increasing from $44 million and $40 million in third quarter 2020, largely driven by higher daily average Hartford Funds AUM. Daily average AUM of $155 billion rose 27% from third quarter 2020 due to increases in market values and strong net inflows over the previous 12 months. Fee income and variable expenses rose with the increase in AUM.

Mutual fund and ETP net inflows totaled $0.3 billion in third quarter 2021, compared with net outflows of $1.3 billion in third quarter 2020.

Corporate

Net loss available to common stockholders of $38 million in third quarter 2021 decreased $76 million compared with third quarter 2020, driven by a decrease in restructuring and other costs and the effect of a loss from the company’s previously owned 9.7% equity interest in Talcott Resolution in the 2020 period, partially offset by a decrease in net realized gains.

Third quarter 2021 core loss of $47 million decreased $10 million compared with third quarter 2020 core loss of $57 million primarily due to a $21 million, before tax, loss in third quarter 2020 from the company's previously owned 9.7% equity interest in Talcott Resolution, partially offset by an increase in expenses.

INVESTMENT INCOME AND PORTFOLIO DATA:

Third quarter 2021 consolidated net investment income of $650 million increased $158 million from $492 million in third quarter 2020 largely driven by higher income from LPs, a higher level of invested assets and higher income from equity investments, partially offset by a lower yield on fixed maturities resulting from reinvesting at lower rates.

Income from LPs was $259 million, before tax, in third quarter 2021, increasing from $83 million, before tax, in third quarter 2020, mostly driven by higher valuations and cash distributions within private equity funds and sales of underlying investments within real estate. Income from LPs, including from private equity and other funds, is generally reported on a three-month lag.

Total invested assets of $57.6 billion increased 2% from Dec. 31, 2020, primarily due to increases in LPs and mortgage loans, partially offset by a decrease in fixed maturities. Valuations of fixed maturities decreased driven by higher interest rates, partially offset by tighter credit spreads.

DISCUSSION OF NON-GAAP FINANCIAL MEASURES

The Hartford uses non-GAAP financial measures in this press release to assist investors in analyzing the company's operating performance for the periods presented herein. Because The Hartford's calculation of these measures may differ from similar measures used by other companies, investors should be careful when comparing The Hartford's non-GAAP financial measures to those of other companies. Definitions and calculations of other financial measures used in this press release can be found below and in The Hartford's Investor Financial Supplement for third quarter 2021, which is available on The Hartford's website, https://ir.thehartford.com.

Annualized investment yield, excluding limited partnerships and other alternative investments - This non-GAAP measure is calculated as (a) the annualized net investment income, on a Consolidated, P&C or Group Benefits level, excluding limited partnerships and other alternative investments, divided by (b) the monthly average invested assets at amortized cost, excluding repurchase agreement and securities lending collateral, derivatives book value, and limited partnerships and other alternative investments. The Company believes that annualized investment yield, excluding limited partnerships and other alternative investments, provides investors with an important measure of the trend in investment earnings because it excludes the impact of the volatility in returns related to limited partnerships and other alternative investments. Annualized investment yield is the most directly comparable GAAP measure.

Book value per diluted share (excluding AOCI) - This is a non-GAAP per share measure that is calculated by dividing (a) common stockholders' equity, excluding AOCI, after tax, by (b) common shares outstanding and dilutive potential common shares. The Company provides this measure to enable investors to analyze the amount of the Company's net worth that is primarily attributable to the Company's business operations. The Company believes that excluding AOCI from the numerator is useful to investors because it eliminates the effect of items that can fluctuate significantly from period to period, primarily based on changes in interest rates. Book value per diluted share is the most directly comparable U.S. GAAP measure.

Core earnings - The Hartford uses the non-GAAP measure core earnings as an important measure of the Company’s operating performance. The Hartford believes that core earnings provides investors with a valuable measure of the performance of the Company’s ongoing businesses because it reveals trends in our insurance and financial services businesses that may be obscured by including the net effect of certain items. Therefore, the following items are excluded from core earnings:

• Certain realized gains and losses - Some realized gains and losses are primarily driven by investment decisions and external economic developments, the nature and timing of which are unrelated to the insurance and underwriting aspects of our business. Accordingly, core earnings excludes the effect of all realized gains and losses that tend to be highly variable from period to period based on capital market conditions. The Hartford believes, however, that some realized gains and losses are integrally related to our insurance operations, so core earnings includes net realized gains and losses such as net periodic settlements on credit derivatives. These net realized gains and losses are directly related to an offsetting item included in the income statement such as net investment income.
• Restructuring and other costs - Costs incurred as part of a restructuring plan are not a recurring operating expense of the business.
• Loss on extinguishment of debt - Largely consisting of make-whole payments or tender premiums upon paying debt off before maturity, these losses are not a recurring operating expense of the business.
• Gains and losses on reinsurance transactions - Gains or losses on reinsurance, such as those entered into upon sale of a business or to reinsure loss reserves, are not a recurring operating expense of the business.
• Integration and other non-recurring M&A costs - These costs, including transaction costs incurred in connection with an acquired business, are incurred over a short period of time and do not represent an ongoing operating expense of the business.
• Change in loss reserves upon acquisition of a business - These changes in loss reserves are excluded from core earnings because such changes could obscure the ability to compare results in periods after the acquisition to results of periods prior to the acquisition.
• Deferred gain resulting from retroactive reinsurance and subsequent changes in the deferred gain - Retroactive reinsurance agreements economically transfer risk to the reinsurers and including the full benefit from retroactive reinsurance in core earnings provides greater insight into the economics of the business.
• Change in valuation allowance on deferred taxes related to non-core components of pre-tax income - These changes in valuation allowances are excluded from core earnings because they relate to non-core components of pre-tax income, such as tax attributes like capital loss carryforwards.
• Results of discontinued operations - These results are excluded from core earnings for businesses sold or held for sale because such results could obscure the ability to compare period over period results for our ongoing businesses.

In addition to the above components of net income available to common stockholders that are excluded from core earnings, preferred stock dividends declared, which are excluded from net income available to common stockholders, are included in the determination of core earnings. Preferred stock dividends are a cost of financing more akin to interest expense on debt and are expected to be a recurring expense as long as the preferred stock is outstanding.

Net income (loss) and net income (loss) available to common stockholders are the most directly comparable U.S. GAAP measures to core earnings. Core earnings should not be considered as a substitute for net income (loss) or net income (loss) available to common stockholders and does not reflect the overall profitability of the Company’s business. Therefore, The Hartford believes that it is useful for investors to evaluate net income (loss), net income (loss) available to common stockholders, and core earnings when reviewing the Company’s performance.

A reconciliation of net income (loss) to core earnings for the quarterly periods ended September 30, 2021 and 2020, is included in this press release. A reconciliation of net income (loss) to core earnings for individual reporting segments can be found in this press release under the heading "The Hartford Financial Services Group, Inc. Consolidating Income Statements" and in The Hartford's Investor Financial Supplement for the quarter ended September 30, 2021.

Core earnings margin - The Hartford uses the non-GAAP measure core earnings margin to evaluate, and believes it is an important measure of, the Group Benefits segment's operating performance. Core earnings margin is calculated by dividing core earnings by revenues, excluding buyouts and realized gains (losses). Net income margin, calculated by dividing net income by revenues, is the most directly comparable U.S. GAAP measure. The Company believes that core earnings margin provides investors with a valuable measure of the performance of Group Benefits because it reveals trends in the business that may be obscured by the effect of buyouts and realized gains (losses) as well as other items excluded in the calculation of core earnings. Core earnings margin should not be considered as a substitute for net income margin and does not reflect the overall profitability of Group Benefits. Therefore, the Company believes it is important for investors to evaluate both core earnings margin and net income margin when reviewing performance. A reconciliation of net income margin to core earnings margin for the quarterly periods ended September 30, 2021 and 2020, is set forth below.

Core earnings per diluted share - This non-GAAP per share measure is calculated using the non-GAAP financial measure core earnings rather than the GAAP measure net income. The Company believes that core earnings per diluted share provides investors with a valuable measure of the Company's operating performance for the same reasons applicable to its underlying measure, core earnings. Net income (loss) available to common stockholders per diluted common share is the most directly comparable GAAP measures. Core earnings per diluted share should not be considered as a substitute for net income (loss) available to common stockholders per diluted common share and does not reflect the overall profitability of the Company's business. Therefore, the Company believes that it is useful for investors to evaluate net income (loss) available to common stockholders per diluted common share and core earnings per diluted share when reviewing the Company's performance. A reconciliation of net income (loss) available to common stockholders per diluted common share to core earnings per diluted share for the quarterly periods ended September 30, 2021 and 2020 is provided in the table below.

Core Earnings Return on Equity - The Company provides different measures of the return on stockholders' equity (ROE). Core earnings ROE is calculated based on non-GAAP financial measures. Core earnings ROE is calculated by dividing (a) the non-GAAP measure core earnings for the prior four fiscal quarters by (b) the non-GAAP measure average common stockholders' equity, excluding AOCI. Net income ROE is the most directly comparable U.S. GAAP measure. The Company excludes AOCI in the calculation of core earnings ROE to provide investors with a measure of how effectively the Company is investing the portion of the Company's net worth that is primarily attributable to the Company's business operations. The Company provides to investors return on equity measures based on its non-GAAP core earnings financial measure for the reasons set forth in the core earnings definition.

A reconciliation of consolidated net income (loss) ROE to Consolidated Core earnings ROE is set forth below.

Net investment income, excluding limited partnerships and other alternative investments -This non-GAAP measure is the amount of net investment income, on a Consolidated, P&C or Group Benefits level earned from invested assets, excluding the net investment income related to limited partnerships and other alternative investments. The Company believes that net investment income, excluding limited partnerships and other alternative instruments, provides investors with an important measure of the trend in investment earnings because it excludes the impact of the volatility in returns related to limited partnerships and other alternative instruments. Net investment income is the most directly comparable GAAP measure.

Underlying combined ratio- This non-GAAP financial measure of underwriting results represents the combined ratio before catastrophes, prior accident year development and current accident year change in loss reserves upon acquisition of a business. Combined ratio is the most directly comparable GAAP measure. The underlying combined ratio represents the combined ratio for the current accident year, excluding the impact of current accident year catastrophes and current accident year change in loss reserves upon acquisition of a business. The Company believes this ratio is an important measure of the trend in profitability since it removes the impact of volatile and unpredictable catastrophe losses and prior accident year loss and loss adjustment expense reserve development. The changes to loss reserves upon acquisition of a business are excluded from underlying combined ratio because such changes could obscure the ability to compare results in periods after the acquisition to results of periods prior to the acquisition as such trends are valuable to our investors' ability to assess the Company's financial performance. A reconciliation of the combined ratio to the underlying combined ratio for individual reporting segments can be found in this press release under the heading "Business Results" for Commercial Lines" and "Personal Lines"

Underwriting gain (loss) - The Hartford's management evaluates profitability of the Commercial and Personal Lines segments primarily on the basis of underwriting gain or loss. Underwriting gain (loss) is a before tax non-GAAP measure that represents earned premiums less incurred losses, loss adjustment expenses and underwriting expenses. Net income (loss) is the most directly comparable GAAP measure. Underwriting gain (loss) is influenced significantly by earned premium growth and the adequacy of The Hartford's pricing. Underwriting profitability over time is also greatly influenced by The Hartford's underwriting discipline, as management strives to manage exposure to loss through favorable risk selection and diversification, effective management of claims, use of reinsurance and its ability to manage its expenses. The Hartford believes that the measure underwriting gain (loss) provides investors with a valuable measure of profitability, before tax, derived from underwriting activities, which are managed separately from the Company's investing activities. A reconciliation of net income to underwriting results for the quarterly periods ended September 30, 2021 and 2020, is set forth below.

Underlying underwriting gain (loss) - This non-GAAP measure of underwriting profitability represents underwriting gain (loss) before current accident year catastrophes, PYD and current accident year change in loss reserves upon acquisition of a business. The most directly comparable GAAP measure is net income (loss). The Company believes underlying underwriting gain (loss) is important to understand the Company’s periodic earnings because the volatile and unpredictable nature (i.e., the timing and amount) of catastrophes and prior accident year reserve development could obscure underwriting trends. The changes to loss reserves upon acquisition of a business are also excluded from underlying underwriting gain (loss) because such changes could obscure the ability to compare results in periods after the acquisition to results of periods prior to the acquisition as such trends are valuable to our investors' ability to assess the Company's financial performance. A reconciliation of net income (loss) to underlying underwriting gain (loss) for individual reporting segments for the quarterly periods ended September 30, 2021 and 2020, is set forth below.
