CY2017	us-gaap	Use Of Estimates UseOfEstimates	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Use of Estimates and Assumptions</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period and accompanying notes. Actual results could differ materially from those estimates and assumptions used. The more significant of these estimates and assumptions include the following:</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Claims</font><font style="font-family:inherit;font-size:10pt;"> – The Company’s reserve for claims is established using estimated amounts required to settle claims for which notice has been received (reported) and the amount estimated to be required to satisfy incurred claims of policyholders which may be reported in the future (incurred but not reported, or “IBNR”). A provision for estimated future claims payments is recorded at the time policy revenue is recorded as a percentage of premium income. By their nature, title claims can often be complex, vary greatly in dollar amounts, vary in number due to economic and market conditions such as an increase in mortgage foreclosures, and involve uncertainties as to ultimate exposure. In addition, some claims may require a number of years to settle and determine the final liability for indemnity and loss adjustment expense. The payment experience may extend for more than </font><font style="font-family:inherit;font-size:10pt;">20</font><font style="font-family:inherit;font-size:10pt;"> years after the issuance of a policy. Events such as fraud, defalcation and multiple property defects can substantially and unexpectedly cause increases in estimates of losses. Due to the length of time over which claim payments are made and regularly occurring changes in underlying economic and market conditions, these estimates are subject to variability.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Management considers factors such as the Company’s historical claims experience, case reserve estimates on reported claims, large claims, actuarial projections and other relevant factors in determining its loss provision rates and the aggregate recorded expected liability for claims. In establishing the reserve, actuarial projections are compared with recorded reserves to evaluate the adequacy of such recorded claims reserves and any necessary adjustments are then recorded in the current period’s income statement. As the most recent claims experience develops and new information becomes available, the loss reserve estimate related to prior periods will change to more accurately reflect updated and improved emerging data. The Company reflects any adjustments to the reserve in the results of operations in the period in which new information (principally claims experience) becomes available.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company’s reserve for claims is established using estimated amounts required to settle claims for which notice has been received (reported) and the amount estimated to be required to satisfy incurred claims of policyholders which have been incurred but not reported (“IBNR”).</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Premiums written</font><font style="font-family:inherit;font-size:10pt;"> – Premium revenues from certain agency operations include accruals for transactions which have settled but have not been reported as of the balance sheet date. These accruals are based on estimates of the typical lag time between settlement of real estate transactions and the agent’s reporting of these transactions to the Company. Reporting lag times vary by market. In certain markets, the lag time may be very short, but in others, can be as high as </font><font style="font-family:inherit;font-size:10pt;">100</font><font style="font-family:inherit;font-size:10pt;"> days. The Company reviews and adjusts lag time estimates periodically, using historical experience and other factors, and reflects any adjustments in the result of operations in the period in which new information becomes available. </font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;text-decoration:underline;">Impairments</font><font style="font-family:inherit;font-size:10pt;"> – Securities are regularly evaluated and reviewed for differences between the cost and estimated fair value of each security for factors that may indicate that a decline in estimated fair value is other-than-temporary. When, in the opinion of management, a decline in the estimated fair value of an investment is considered to be other-than-temporary, such investment is written down to its estimated fair value. Some factors considered in evaluating whether or not a decline in estimated fair value is other-than-temporary include the duration and extent to which the estimated fair value has been less than cost; the probability that the Company will be unable to collect all amounts due under the contractual terms of the security; with respect to equity securities, whether the Company’s ability and intent to retain the investment for a period of time is sufficient to allow for a recovery in value; with respect to fixed maturity securities, whether the Company has the intent to sell or will more likely than not be required to sell a particular security before recovery in value; and the financial condition and prospects of the issuer (including credit ratings). These factors are reviewed quarterly and any material degradation in the prospect for recovery will be considered in the other-than-temporary impairment analysis. Such reviews are inherently uncertain and the value of the investment may not fully recover or may decline in future periods resulting in a realized loss. The estimated fair values of the majority of the Company’s investments are based on quoted market prices from independent pricing services.</font></div></div>
