The continul extend has a no lapse guarantee, as stated in the illustration.
The illustration is the most important legal doc concerning uls' and is a simple tool for understanding their cash value and reduction.
AG's continul extend is very hard to beat, due to the tables are scaled at 15%. WCL, even if they approved it at the same table, would be slightly higher.
WCL's standard rate would be $3200/year versus $4400/year on the AG ContinUL Extend, so it would still likely be significantly cheaper when multiplied out by the table ratings. Still, they'd probably be better off with the term insurance and pocketing the difference since the death benefit would be paid up in 15 years anyway. The WCL 15-year standard rate is $2361/year, which would save him somewhere around $2k/year. American General's 15-year rate is $2918 at standard.
