The Company pledges securities as collateral for the repurchase agreements. Refer to Note 4—Securities for additional discussion.

On October 13, 2016, the Company entered into a $30.0 million credit agreement with a correspondent bank. In April 2017, the revolving line of credit was amended to a non-revolving line of credit as long as the outstanding balance exceeds $5.0 million. When the outstanding balance is reduced to $5.0 million, the line of credit will be converted to a revolving line of credit with credit availability up to $5.0 million until maturity. In July 2017, the Company repaid the outstanding balance, in full, under this line of credit of $16.2 million with proceeds from its initial public offering (“IPO”). Prior to its maturity on October 10, 2019, the line of credit carried an interest rate at either the London Interbank Offered Rate (“LIBOR”) for the applicable interest period plus 225 basis points or the Prime Rate minus 50 basis points, based on the Company’s election. On April 30, 2019, the Company drew on the line of credit for $5.7 million and selected the LIBOR plus 225 basis points interest rate option, which was the interest rate option at the time of the draw. The funds were utilized to repay a line of credit assumed as a result of the Oak Park River Forest acquisition. The Company repaid the $5.7 million outstanding balance of the line of credit in full on May 31, 2019. On October 10, 2019, the Company entered into a fourth amendment to the revolving credit agreement, which increased the revolving loan commitment to $15.0 million and extended the maturity of the credit facility to October 9, 2020. The amended revolving line of credit bears interest at either LIBOR plus 195 basis points or Prime Rate minus 75 basis points, based on the Company’s election, which is required to be communicated at least three business days prior to the commencement of an interest period. If the Company fails to provide timely notification, the interest rate will be Prime Rate minus 75 basis points. As of December 31, 2019 and 2018, the line of credit had no outstanding balance, therefore an interest rate option has not been selected.
