The total number of securities with unrealized losses at June 30, 2020, and June 30, 2019 were 24 and 100, respectively. Unrealized losses on securities have not been recognized in income because management has the intent and ability to hold the securities for the foreseeable future, and has determined that it is not more likely than not that the Company will be required to sell the securities prior to a recovery in value. The increase in fair value was largely due to decreases in market interest rates. The Company had no other than temporary impairment losses during the years ended June 2020, 2019 or 2018.
