Supplementary Regulatory Capital Disclosure
The Company's subsidiary, WEX Bank is subject to various regulatory capital requirements administered by the FDIC and the Utah Department of Financial Institutions. Failure to meet minimum capital requirements can initiate certain mandatory, and possible additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, WEX Bank must meet specific capital guidelines that involve quantitative measures of WEX Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. WEX Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
Quantitative measures established by regulation to ensure capital adequacy require WEX Bank to maintain minimum amounts and ratios as defined in the regulations. As of December 31, 2015, the most recent FDIC exam report categorized WEX Bank as “well capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events subsequent to that examination report that management believes have changed WEX Bank’s capital rating.
