Peyton Manning signed a 5 year - $96,000,000 contract with the Denver Broncos.

That includes $58,000,000 guaranteed, and an annual average salary of $19,200,000.

His CAP hit in 2015 will be $21.5M$

from that link:
2015 salary gauarantees if on the roster at the end of 2014 (spelling theirs)

It doesn't give a date for the guarantee activating. I'd guess the last day of the league year.
