The Corporation evaluates individual investment securities quarterly for other-than-temporary declines in market value. At December 31, 2020, $17,000 of the $81,000 unrealized holding losses were 12 months or more; while at June 30, 2020, $17,000 of the $69,000 unrealized holding losses were 12 months or more. The unrealized losses on investment securities were attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. At December 31, 2020 and 2019, the Corporation did not have any investment securities with the intent to sell and determined it was more likely than not that the Corporation would not be required to sell the securities prior to recovery of the amortized cost basis; therefore, no impairment losses were recorded for the quarter ended December 31, 2020 and 2019.

Contractual maturities of investment securities as of December 31, 2020 and June 30, 2020 were as follows:
