He passed at the age of 78 on Dec 2018.
This year I am 78.
In 2019 the company still using his RMD with uniform life table which I took the RMD. In 2020 they changed it to Actuarial Life Expectancy Factor but since it was not required to take it, I didn’t pay attention to it and didn’t take the RMD.
Now for 2021 I just noticed it, more than double the amount.
