In FY16, we are expecting some reduced aircraft per contract with a few project cancellations, leading to reduced activity and an increase in supply of available aircraft. • Bristow is executing on specific plans during this downturn to reduce costs Finalize internal restructurings put in place in Q2 FY15 Proactively work with clients to find efficiencies and ways to reduce costs, without compromising safety Partner with original equipment manufacturers (OEMs) and lessors during this downturn to find cost and capital efficiencies 7
