| APPENDIX A |

### Appendix A: Reconciliation of Non-GAAP Financial Measures
Assurant uses the following non-GAAP financial measures in this proxy statement to analyze the Company’s operating performance. Assurant’s non-GAAP financial measures should not be considered in isolation or as a substitute for GAAP financial measures. Because Assurant’s calculation of these measures may differ from similar measures used by other companies, investors should be careful when comparing Assurant’s non-GAAP financial measures to those of other companies.

Assurant uses net operating income, excluding reportable catastrophes (which represents individual catastrophic events that generate losses in excess of $5.0 million, pre-tax, net of reinsurance and client profit sharing adjustments and including reinstatement and other premiums), per diluted share as an important measure of the Company's stockholder value in this proxy statement. Net operating income equals GAAP net income (or net income from continuing operations), excluding net realized losses (gains) on investments and fair value changes to equity securities, non-core operations and restructuring costs related to strategic exit activities, as well as other highly variable or unusual items. Assurant defines this metric as net operating income, excluding reportable catastrophes (each as defined above), plus any dilutive preferred stock dividends, divided by the weighted average diluted shares outstanding. The Company believes this metric provides investors with an important measure of stockholder value because the excluded items do not represent the ongoing operations of the Company, and it excludes reportable catastrophes, which can be volatile. The comparable GAAP measure is net income (or net income from continuing operations) per diluted share, defined as net income (or 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.
