Actual maturities may differ from contractual maturities because some securities may be called or prepaid. Because of the potential for prepayment on mortgage-backed securities, they are not categorized by contractual maturity. Proceeds from the sales of available-for-sale securities were $40 million in 2018, $403 million in 2017, and $62 million in 2016. Realized gains were not significant in 2018 and 2016 and were $275 million in 2017 (see Note 5). 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 2018, 2017, and 2016. Unrealized losses at October 28, 2018 and October 29, 2017 were primarily the result of an increase in interest rates and 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.
