Your policy has a birthday, and it's the one day a year the policy asks something of you. Not money. Attention. Every year around the anniversary, the company issues an annual statement, and twenty minutes with it keeps small problems from becoming expensive ones.
Start by putting the statement next to the original illustration. Is the actual cash value tracking the illustrated column? One soft year means very little, since dividends and credited rates move around. A gap that widens for several years running is a conversation to have with your agent, and catching it in year four beats discovering it in year fifteen.
Watch for this: an IUL statement can show a respectable credited rate while rising insurance charges eat a growing share of it, because those charges climb with your age. Don't stop at the rate. Look at the net change in cash value for the year, since that single number includes everything pulling in both directions.
If you carry a policy loan, the anniversary is the day to look it in the eye. Unpaid loan interest gets added to the balance, and a loan that only ever grows is drifting toward the lapse scenario that turns years of tax-free growth into a taxable event. You set your own payback schedule with a policy loan, which is a feature right up until nobody's watching it. Nobody Bills You for a Policy Loan. Set a Schedule Anyway. covers the fix.
Then check the people. Beneficiaries current? Marriages, divorces, and births have a way of outrunning paperwork, and the beneficiary form controls who gets paid regardless of what your will says. Confirm addresses and payment method while you're in there.
That's the whole ritual. Twenty minutes, once a year, calendar reminder on the policy's anniversary date. Then put the statement away and go live your life. Owning this asset isn't supposed to be a hobby.
