UNITED FIRE GROUP INC

We evaluate profit or loss based upon operating and investment results. Profit or loss described in the following sections of this Management's Discussion and Analysis is reported on a pre-tax basis. Our primary sources of revenue are premiums and investment income. Major categories of expenses include losses and loss settlement expenses, underwriting and other operating expenses. Management uses metrics to provide financial statement users with a better understanding of results of operations, including adjusted operating income and three components of the loss ratio: underlying loss ratio, impacts of catastrophes and non-catastrophe prior period reserve development.

Adjusted operating income is calculated by excluding net investment gains and losses, after applicable federal and state income taxes from net income (loss). Management believes adjusted operating income is a meaningful measure for evaluating insurance company performance and a useful supplement to GAAP information because it better represents the normal, ongoing performance of our business. Investors and equity analysts who invest in and report on the insurance industry and the Company generally focus on this metric in their analyses.

Underlying loss ratio represents the net loss ratio less the impacts of catastrophes and non-catastrophe prior period reserve development. The underlying combined ratio represents the combined ratio less the impacts of catastrophes and non-catastrophe prior period reserve development. The Company believes that the underlying loss ratio and underlying combined ratio are meaningful measures to understand the underlying trends in the core business in the current accident year, removing the volatility of catastrophes and prior period impacts. Management believes separate discussions on catastrophe losses and prior period reserve development are important to understanding how the Company is managing catastrophe risk and in identifying developments in longer-tailed business.

Catastrophe losses is an operational measure that utilizes the designations of the Insurance Services Office ("ISO") and is reported with losses and loss adjustment expense amounts net of reinsurance recoverables, unless specified otherwise. In addition to ISO catastrophes, we also include as catastrophes those events which may include U.S. or international losses, that we believe are, or will be, material to our operations, either in amount or in number of claims made. Catastrophes are not predictable and are unique in terms of timing and financial impact. While management estimates catastrophe losses as incurred, due to the inherently unique nature of catastrophe losses, the impact in a reporting period is inclusive of catastrophes that occurred in the reporting period, as well as development on catastrophes that may have occurred in prior periods.

Prior period reserve development is the increase (unfavorable) or decrease (favorable) in incurred loss and loss adjustment expense reserves at the valuation dates for losses which occurred in previous calendar years. This measure excludes development on catastrophe losses.
