Exhibit 99.1

Glossary of Selected Terms

The following measures are used by the
Companys management to evaluate performance against historical results and establish targets on a consolidated basis. A number of these measures are components of net income or the balance sheet but, in some cases, may be considered non-GAAP
financial measures under applicable SEC rules because they are not displayed as separate line items in the Consolidated Statement of Operations or Consolidated Balance Sheets, and in some cases, there is inclusion or exclusion of certain items not
ordinarily included or excluded in a GAAP financial measure. In the opinion of the Companys management, a discussion of these measures is meaningful to provide investors with an understanding of the significant factors that comprise the
Companys periodic results of operations and financial condition.

Catastrophe costs  The sum of catastrophe losses and property and casualty catastrophe
reinsurance reinstatement premiums.

Catastrophe losses - In categorizing property and casualty claims as being from a
catastrophe, the Company utilizes the designations of the Property Claims Service, a subsidiary of Insurance Services Office, Inc., and additionally beginning in 2007, includes losses from all such events that meet the definition of covered loss in
the Companys primary catastrophe excess of loss reinsurance contract, and reports loss and loss adjustment expense amounts net of reinsurance recoverables. A catastrophe is a severe loss resulting from natural and man-made events within a
particular territory, including risks such as hurricane, fire, earthquake, windstorm, explosion, terrorism and other similar events, that causes $25 million or more in insured property and casualty losses for the industry and affects a significant
number of property and casualty insurers and policyholders. Each catastrophe has unique characteristics. Catastrophes are not predictable as to timing or amount of loss in advance. Their effects are not included in earnings or claim and claim
adjustment expense reserves prior to occurrence. In the opinion of the Companys management, a discussion of the impact of catastrophes is meaningful for investors to understand the variability in periodic earnings.

Insurance premiums written and contract deposits - Premiums written represent (1) the amount charged for policies issued during a
fiscal period for property and casualty business, such amounts may be earned and included in financial results over future fiscal periods, and (2) the amount charged for policies in force during a fiscal period for traditional life and group
life business. Amounts are reported net of reinsurance, unless otherwise specified. Contract deposits include amounts received from customers on deposit-type contracts, such as annuities and interest-sensitive life policy accounts, including deposit
amounts and any related contract or policy fees. Management utilizes this non-GAAP measure, which is based on statutory accounting principles, in analyzing and evaluating the business growth of its operating segments. Insurance premiums and contract
charges earned is the most directly comparable GAAP measure.

Net income before realized investment gains and losses - Net income
adjusted to exclude after tax realized investment gains and losses. Net income is the most directly comparable GAAP measure. Management believes that a projection of net income including after tax realized investment gains and losses is not
appropriate on a forward-looking basis because it is not possible to provide a valid forecast of realized investment gains and losses, which can vary substantially from one period to another and may have a significant impact on net income.

Net Reserves - Property and casualty unpaid claim and claim expense reserves net of anticipated reinsurance recoverables.

Prior Years Reserve Development - A measure which the Company reports for its property and casualty segment which
identifies the increase or decrease in net incurred claim and claim adjustment expense reserves at successive valuation dates for claims which occurred in previous calendar years. In the opinion of the Companys management, a discussion of
prior years loss reserve development is useful to investors as it allows them to assess the impact on current period earnings of incurred claims experience from the current calendar year and previous calendar years.

the consideration of investment income.

| |  |  | Combined Ratio Excluding Catastrophes and Prior Years Reserve Development - The sum of the Loss Ratio and the Expense Ratio adjusted to remove

Return on equity - The ratio of (1) trailing 12-month net income to (2) the average of ending shareholders equity for the current quarter end and the preceding four quarter ends.

Sales or Annualized New Sales - Sales represent the amount of new business sold during the period and exclude renewal of policies
sold in previous periods. Sales are measured by the Company as premiums and deposits to be collected over the 12 months following the sale of a new policy, and this time period may extend into the following calendar year. In addition to the
Companys products, sales data includes authorized products sold by Employee Agents, Exclusive Agents, and their licensed staff which are underwritten by third-party vendors. Sales should not be viewed as a substitute for any financial measure
determined in accordance with GAAP, including sales as it relates to non-insurance companies, and the Companys definition of sales might differ from that used by other companies. The Company utilizes sales information as a
performance measure that indicates the productivity of its agency force. Sales are also a leading indicator of future revenue trends.
