This has been talked about a few times here and lots of info available throughout the internet on this interest rate impact on pensions in general.
To be optimized under the Allstate lump sum pension, you need to be opted in under the old method, have 20 or more years with the company, and be 55 or older. If you are ALL three of those things, run the numbers on the pension calculator comparing lump sum payments with a date of 11/30/22 vs 12/31/22. The difference is how much you’ll lose due to the interest rate change. Then submit your retirement asap.
Those who are younger have time to see interest rates go back down. Those who haven’t been with the company at least 15 years are on the newer pension plan with a different calculation and much less impact.
