Note 5. Borrowings

The Company classifies all borrowings that will mature within a year from the date on which the Company enters into them as short-term borrowings. Short-term borrowings sources consist of federal funds purchased, overnight repurchase agreements (which are secured transactions with customers that generally mature within one to four days), and advances from the FHLB.

The Company maintains federal funds lines with several correspondent banks to address short-term borrowing needs. At March 31, 2018 and December 31, 2017 the remaining credit available from these lines totaled $55.0 million and $45.0 million, respectively. The Company has a collateral dependent line of credit with the FHLB with remaining credit availability of $223.0 million and $217.0 as of March 31, 2018 and December 31, 2017, respectively.
