Barclays and UBS have each secured one of their largest US advisory mandates of 2015, after the two were hired by acquisitive consumer brands group Jarden Corp to advise it on its own $18.4 billion agreed takeover bid by Newell Rubbermaid.

Jarden and Newell Rubbermaid, another owner of various consumer goods brands, announced on December 14 they would form an enlarged company called Newell Brands. Jarden's shareholders will receive $21 in cash and 0.862 Newell Rubbermaid shares for each of their shares, while Newell Rubbermaid's shareholders will own 55% of the combined company.
