(1)	We have deemed it unnecessary to record any liability for credit losses on these agreements.


(2)	The amount of standby letters of credit outstanding excludes commitments to issue standby letters of credit that expire within one year. At March 31, 2020, and December 31, 2019, these amounts totaled $11.5 million and $27.2 million,

respectively. Also excluded are commitments to issue standby letters of credit that expire after one year totaling $550 thousand and $1.8 million at March 31, 2020, and December 31, 2019, respectively.

(3)

Commitments for unused line-of-credit advances are generally for periods of up to 12 months. Since many of these commitments are not expected to be drawn upon, the total commitment amount does not necessarily indicate future liquidity requirements.
