APPENDIX

BASIS OF PRESENTATION

Commercial Lines provides workers’ compensation, property, automobile, general liability, umbrella, professional liability, bond, marine, livestock and accident and health reinsurance to businesses in the United States ("U.S.") and internationally. Commercial Lines generally consists of products written for small businesses, middle market companies and national accounts, largely distributed through retail agents and brokers, wholesale agents and global and specialty reinsurance brokers. Small commercial and middle market lines within middle & large commercial are generally referred to as standard commercial lines. Global specialty provides a variety of customized insurance products, including reinsurance.

DISCUSSION OF NON-GAAP AND OTHER FINANCIAL MEASURES

The Company uses non-GAAP and other financial measures in this Investor Financial Supplement to assist investors in analyzing the Company's operating performance. Because the Company's calculation of these measures may differ from similar measures used by other companies, investors should be careful when comparing the Company's non-GAAP and other financial measures to those of other companies. Non-GAAP measures are indicated with an asterisk the first time they appear in this document.

Underwriting gain (loss) is a before tax measure that represents earned premiums less incurred losses, loss adjustment expenses and underwriting expenses and policyholder dividends. Underwriting gain (loss) is influenced significantly by earned premium growth and the adequacy of the Company's pricing. Underwriting profitability over time is also greatly influenced by the Company's pricing and underwriting discipline, which seeks to manage exposure to loss through favorable risk selection and diversification, its management of claims, its use of reinsurance and its ability to manage its expense ratio, which it accomplishes through its management of acquisition costs and other underwriting expenses. Net income (loss) is the most directly comparable U.S. GAAP measure. The Company believes that underwriting gain (loss) provides investors with a valuable measure of before tax profitability derived from underwriting activities, which are managed separately from the Company's investing activities. A reconciliation of net income (loss) to underwriting gain (loss) for Commercial Lines reporting segment is set forth and available on The Hartford’s Investor Financial Supplement for first quarter 2019 filed with the Securities and Exchange Commission ("SEC"), on May 1, 2019 and fourth quarter 2018 filed with the SEC on February 4, 2019, and available at the Investor Relations section of The Hartford’s website at https://ir.thehartford.com.

Underlying combined ratio is a non-GAAP financial measure. Combined ratio is the most directly comparable GAAP measure. Underlying combined ratio represents the combined ratio before catastrophes and prior accident year development. 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. A reconciliation of the combined ratio to the underlying combined ratio Commercial Lines is set forth on page 1.
