Announced with benchmark size, we heard initial thoughts as T+210 area.

Went straight to launch at $750m 7y at T+175.

Ultimately, a $750m deal priced as follows:

$750m 5.854% 5/13/32 100.00 5.854% T+175. MW+30.

As for r/v, the only outstanding Gold Fields priced back in 2019. It is now pretty illiquid we heard some had the outstanding trading as wide as G165. With no great peers pricing recently, we’re going CONCESSION N/A.
