Overseas Shipholding Group Inc investors have reached $16.25 million in settlements with the executives, underwriters and an auditor of the tanker company in a lawsuit related to its 2012 bankruptcy and tax problems. Company directors and officers, including former Chief Executive Morten Arntzen and former Chief Financial Officer Myles Itkin, agreed to pay $10.5 million, papers filed in Manhattan federal court on Thursday showed. Underwriters including Citigroup Inc, Deutsche Bank AG and Goldman Sachs Group Inc will pay $4 million, while accounting firm PricewaterhouseCoopers LLP will pay $1.75 million. "We're think its an extraordinary result in an extremely complex case," David Rosenfeld, a lawyer for the plaintiffs, said on Friday.
