105(h) Nondiscrimination -- premiums

[elmobob14]

Can an employer pay disparate premiums for highly compensated and nonhighly compensated under a self-insured plan? That is, contributing a higher percentage of premiums for the highly paid?

I've read Treas. Reg. 1.105-11, but it reads like it applies only to the actual benefits paid under the plan on claims made. I've also read a number of white papers that suggest that paying more premiums for the highly compensated violates Code Section 105, but I can't see where this follows in the Regs.
