WASHINGTON, July 22 (Reuters) - The U.S. Treasury said on Wednesday it earned a 23.15 percent annualized return on its $10 billion investment in Goldman Sachs Group Inc., including stock warrants redeemed by the Wall Street giant for $1.1 billion.

“In just 9 months, the taxpayers have been repaid the full $10 billion that the government originally invested, along with $318 million in dividends,” a Treasury official said in a statement.

“And Goldman is repurchasing the warrants for $1.1 billion, generating a total of $1.418 billion in payments to the government. That amounts to an annualized return of 23.15 percent on the taxpayer’s investment,” the official added.
