The PSLRA provides a safe harbor under the Securities Act of 1933 and the Securities Exchange Act of 1934 for forward-looking statements. These statements relate to our intentions, beliefs, projections, estimations, or forecasts of future events or our future financial performance and involve known and unknown risks, uncertainties, and other factors that may cause our or our industry’s actual results, levels of activity, or performance to be materially different from those expressed or implied by the forward-looking statements. In some cases, you can identify forward-looking statements by use of words such as “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “target,” “project,” “intend,” “believe,” “estimate,” “predict,” “potential,” “pro forma,” “seek,” “likely,” or “continue” or other comparable terminology. These statements are only predictions, and we can give no assurance that such expectations will prove to be correct. We undertake no obligation, other than as may be required under the federal securities laws, to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

Non-GAAP operating income, non-GAAP operating earnings per share, and non-GAAP operating return on equity differ from net income, earnings per share, and return on equity, respectively, by the exclusion of after-tax net realized gains and losses on investments, the deferred tax write-off that was recognized in 2017 in relation to tax reform, and the results of discontinued operations, if any. They are used as important financial measures by management, analysts, and investors, because the realization of net investment gains and losses in any given period is largely discretionary as to timing. In addition, these net realized investment gains and losses, the deferred tax write-off, as well as other-than-temporary investment impairments that are charged to earnings and the results of discontinued operations, could distort the analysis of trends. These operating measurements are not intended as a substitute for net income, earnings per share, or return on equity prepared in accordance with U.S. generally accepted accounting principles (GAAP). Reconciliations of net income, earnings per share, and return on equity to non-GAAP operating income, non-GAAP operating earnings per share, and non-GAAP operating return on equity, respectively, are provided in the tables above. Statutory data is prepared in accordance with statutory accounting rules as defined by the National Association of Insurance Commissioners Accounting Practices and Procedures Manual and, therefore, is not reconciled to GAAP.
