Line of Credit	8. LINE OF CREDIT: The Company renewed its loan agreement, effective June 30, 2017, with Frost Bank. Under the loan agreement, as renewed and amended, we are permitted to draw up to $25,000,000 on a revolving line of credit. Prior to June 30, 2019, interest is paid quarterly at The Wall Street Journal Prime Rate and the line of credit matures June 30, 2019. If a balance exists at June 30, 2019, the principal balance converts to a term facility payable quarterly over five years and interest is paid quarterly at our election at The Wall Street Journal Prime Rate plus 50 basis points or LIBOR plus 250 basis points. The line of credit is unsecured. Among other provisions in the credit agreement, we must satisfy certain financial covenants during the term of the loan agreement, including, without limitation, covenants that require us to maintain certain capital, tangible net worth, loan loss reserve, non-performing asset and cash flow coverage ratios. In addition, the credit agreement contains certain operational covenants, which among others, restricts the payment of dividends above 55% of consolidated net income, limits the incurrence of debt (excluding any amounts acquired in an acquisition) and prohibits the disposal of assets except in the ordinary course of business. Since 1995, we have historically declared dividends as a percentage of our consolidated net income in a range of 37% (low) in 1995 to 53% (high) in 2003 and 2006. The Company was in compliance with the financial and operational covenants at December 31, 2018. There was no outstanding balance under the line of credit as of December 31, 2018 or 2017.
