Because of the potential for prepayment on mortgage-backed securities, they are not categorized by contractual maturity. Proceeds from the sales of debt securities, realized gains, realized losses, the increase (decrease) in net unrealized gains or losses, and unrealized losses that have been continuous for over twelve months were not significant in 2021, 2020, and 2019. Unrealized losses at October 31, 2021 and November 1, 2020 were not recognized in income due to the ability and intent to hold to maturity. There were no significant impairment write-downs in the periods reported.
