Other Borrowings | Note 13—Other Borrowings The following is a summary of the Company’s other borrowings as of December 31, 2017 and 2016:

Total |  | $ | 31,187 |  |  | $ | 37,899 |
Securities sold under agreements to repurchase represent a demand deposit product offered to customers that sweep balances in excess of the FDIC insurance limit into overnight repurchase agreements. The Company pledges securities as collateral for the repurchase agreements. Refer to Note 4—Securities for additional discussion. On October 13, 2016, in connection with the Ridgestone acquisition, the Company entered into a $30.0 million credit agreement with The PrivateBank and Trust and Company, now known as CIBC Bank USA (“CIBC”), with a $300,000 commitment fee payable at such time. At December 31, 2016, the interest rate was 3.75%. 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 reaches $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”). The line of credit matured on October 12, 2017 and carried an interest rate equal to the Prime Rate. On October 12, 2017, the Company amended the credit agreement, which extended the maturity date to October 11, 2018. The amended revolving line of credit bears interest at either the London Interbank Offered Rate (“LIBOR”) Rate plus 250 basis points or the Prime Rate minus 25 basis points, based on the Company’s election, which is required to be communicated to CIBC 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 25 basis points. As of December 31, 2017, the line of credit has not been drawn upon, so an interest rate option has not been selected. Note 13—Other Borrowings (continued) The following table presents short-term credit lines available for use, for which the Company did not have an outstanding balance as of December 31, 2017 and 2016:
