Linklaters and Davis Polk & Wardwell have taken lead roles on a $2bn (£1.3bn) notes offering by Rio Tinto, which saw the mining giant take advantage of current low yields on corporate bonds to reduce its debt costs.

Linklaters advised Rio – a longstanding client of the firm – on the offering, which is split into three parts, comprising $500m (£324m) of notes due in 2016, $1.15bn (£746m) due in 2021 and $350m (£227m) due in 2040.
