Ally has received about 90 percent of the total proceeds expected from the sales of non-U.S. companies.
Ally, formerly known as GMAC Inc., was owned by General Motors Corp. until 2006, when the automaker sold 51 percent to Cerberus Capital Management LP, a private-equity firm. The holding was later diluted by a $17.2 billion U.S. bailout during the financial crisis. As part of the bailout, the U.S. Treasury took a 74 percent stake in the company and later renamed it Ally.
"Ally is in a much stronger position today to further strengthen its domestic franchises and advance it efforts to repay the U.S. taxpayer," Carpenter said.
In April, Ally sold the majority of its overseas operations in Europe and Latin America to GM Financial for about $2.6 billion. The purchase includes operations in Germany, United Kingdom, France, Portugal, Italy, Sweden, Switzerland, Austria, Belgium, the Netherlands, Chile, Colombia and Mexico.
The international acquisitions, announced in November 2012, also cover a stake in a joint venture in China, which is pending certain regulatory and other approvals. GM Financial expects to close the deal in 2014.
When fully completed the deal will roughly double GM Financial in size in terms of assets to $30 billion, GM Financial said Tuesday. Ally listed $150.6 billion in assets as of June 30, 2013.
