Multiple Liability Duration Match Method 今年变了吗？

hi,  just wanted to clarify, for the Multiple Liability Duration Match Method:

one of the conditions in the past year was the dispersion of the cash flow is greater than the liability, i.e. the distribution of Cash Flow to Asset is greater than Liability ->早过开始晚过结束. Is this condition being released now? I don't see the condition being mentioned in the class:  it is MVa > MVl; BPVa= BPVl; Convexity A > Convexity l.

Kindly verify.
