Quarterly Financial Information Disclosure [Abstract]

Quarterly Financial Data (unaudited)

The following unaudited quarterly financial data is presented on a consolidated basis for each of the years ended December 31, 2017 and December 31, 2016. Quarterly financial results necessarily rely heavily on estimates. This and certain other factors, such as the seasonal nature of portions of the insurance business, suggest the need to exercise caution in drawing specific conclusions from quarterly consolidated results.
