Walay monthly, there is quarterly, semi annual and annual.
I have one here for 24 years old, my gf. It's still the same. Since cost of insurance is cheaper for females and at 24, then the rest will go to the investment fund. Take note that the insurance component is deducted monthly and depends on the attained age. Also, the amount that goes to investments is net of management fees.
On the 4th year, the total amount less the cost of insurance and rider(s) will go to investments but again, net of management fees. This is what Bro Makie is emphasizing that it's not really 100% that will go to investments.
