Твёрдого контракта нет, наши СМИ соврали, как всегда :-))

"FARNBOROUGH -- Pearl Aircraft Corporation, a new Bermuda based lessor, has announced memorandum of understanding to purchase 30 Sukhoi Superjet aircraft plus 15 options. The order marks the first order for the 100 seat jetliner in the North American market."
