Valuing a deferred fixed index annuity

I am 69 years old, retired for the past year, and one of my IRAs is a 
Corebridge Financial Power Index 5 single premium deferred fixed index 
annuity, linked to the S&P 500, MSCI EAFE, and the Russell 500, with an 
annual 9.5% cap. This 5-year contract just passed its 1-year anniversary.

I’ve been valuing the account for the past year by applying the daily 
price history downloaded by Quicken for the S&P 500 and Russell indices. 
MSCI EAFE doesn’t appear to be downloadable, so I periodically go to the 
Corebridge website for price updates.

Since the past year has been a good one for equities, the 9.5% cap was 
applied to the account, so I’ve been over-valuing it.

I’d like to adjust the account to better show the value throughout the 
past year. My initial idea is to delete all the daily prices and 
substitute (maybe monthly) prices that are 9.5% higher each month.

Any better ideas?

Thanks
