July 29 (Reuters) - Chesapeake Energy Corp said it would spend $1.26 billion to buy back all of the outstanding preferred shares issued by its CHK Utica unit to simplify its balance sheet and eliminate about $75 million in annual dividend payments.
The natural gas producer also said it would exchange some acreage in Wyoming's Powder River Basin with a private oil and gas producer RKI Exploration & Production LLC to consolidate its holdings in the southern portion of the basin.
Chesapeake will pay RKI $450 million as part of the deal.
