ETP had allowed shareholders to choose whether they wanted to receive the proceeds of the sale as cash or ETP units. Most opted for cash. But the terms allowed for only $2.6 billion to be paid in cash, so most shareholders will receive cash and ETP units.
Owners of 4 percent of Sunoco shares elected to take only ETP units.
Many market watchers had expected ETP's units to decline Friday on the New York Stock Exchange under pressure from Sunoco shareholders seeking to unload their new ETP units.
But ETP units closed at $43.59, up $1.97, or 4.7 percent. About 8.5 million units changed hands, or six times normal volume.
The tax implications for the sale could be profound for Sunoco shareholders.
For federal income-tax purposes, Sunoco shareholders will generally recognize a gain or loss on the cash portion they received. But the exchange of ETP shares for Sunoco shares is a tax-free event. Shareholders report a gain or loss only when they sell the ETP units.
Ownership of the ETP units may be a new experience for Sunoco shareholders. ETP is a master limited partnership, not a corporation. Its publicly traded securities are actually partnership units, whose distributions are taxed and reported to the government differently from common stock dividends.
ETP also took on about $965 million of outstanding Sunoco debt as part of the sale.
Sunoco Inc. will be held inside an ETP holding company, and its primary business will be the retail marketing of fuels and merchandise through Sunoco's 4,900 gas stations and convenience stores.
Ownership of Sunoco Logistics, which operates a network of pipelines and storage terminals, will be held directly by ETP. Sunoco Logistics is building a pipeline, called Mariner East, to transport liquid by-products of Marcellus Shale natural gas to Marcus Hook, site of a former Sunoco refinery, where the fuels will be processed, stored, and shipped by sea.
