Calculation of 415 max. lump sum benefit in year after plan termination date

Thanks for your help in advance.

A DB plan terminates on December 31, 2021.  The distribution for the owner (only participant) will take place in early 2022 (will be age 63 or so).  Highest 3 year average = 285K so benefit will be based on 415 dollar limit. 

Is the calculation of the maximum lump sum benefit to be paid in 2022 based on $230,000 (in effect on plan termination date) or $245,000 (the new limit for 2022 since will be paid in 2022)?

Thanks

If accrued benefits were not frozen at plan termination date - $245,000. If accrued benefits were frozen at plan termination date, it depends on the language of the freeze amendment: no special language - $230,000; allowing increase in 415 dollar limit post benefit freeze - $245,000.

Thank you Calavera!
