NON-GAAP Financial Measures

2. Assurant uses net operating income, excluding reportable catastrophes (defined above), per diluted share as an important measure of the company’s stockholder value. Net operating income, excluding reportable catastrophes, per diluted share equals net operating income, excluding reportable catastrophes, plus any dilutive preferred stock dividends divided by the weighted average number of diluted shares outstanding. The company believes this metric provides investors with an important measure of stockholder value because it excludes items that do not represent the ongoing operations of the company, and it also excludes reportable catastrophes, which can be volatile. The comparable GAAP measure is net income from continuing operations per diluted share, defined as net income from continuing operations plus any dilutive preferred stock dividends less net income from non-controlling interests divided by the weighted-average number of diluted shares outstanding.

3. Assurant uses Adjusted EBITDA, excluding reportable catastrophes, as an important measure of the company’s operating performance. Assurant defines Adjusted EBITDA, excluding reportable catastrophes, as net operating income, excluding reportable catastrophes (defined above), excluding interest expense, provision (benefit) for income taxes, depreciation expense and amortization of purchased intangible assets. The company believes Adjusted EBITDA is a better representation of the company’s operating performance, as compared to net operating income, because it reflects the company’s ongoing shift to more service-oriented, fee-based businesses, and it excludes amortization of purchased intangible assets related to acquisitions. The company believes it (i) enhances management’s and investors’ ability to analyze the ongoing operations of its businesses and (ii) facilitates comparisons of its operating performance over multiple periods, as the amortization expense associated with purchased intangible assets may fluctuate from period to period based on the timing, size, nature and number of acquisitions. Although the company excludes amortization of purchased intangible assets from Adjusted EBITDA, revenue generated from such intangible assets is included within the revenue in determining Adjusted EBITDA. In addition, it excludes reportable catastrophes, which can be volatile. The comparable GAAP measure is net income from continuing operations.
