In order to generate cash and improve liquidity, commodity trader Noble Group Ltd. Inked a deal to purchase its American energy business to US power generation company Calpine Corporation for $1.05 billion.

The deal is the latest action in a series of undertakings designed to lower its debt as well as improve its reputation. Shares of Noble have staggered badly since February 2015, when an anonymous research group accused it of questionable accounting methods. Noble insists it did nothing wrong, and even accelerated disclosures. Poor showing of commodity prices did not help the poor earnings experienced by the company.

Therefore, in order to create cash and ease liquidity, Noble announced a series of sales of assets and reduced expenditures.

In a statement released to the Singapore Exchange, Noble announced that it will receive $800 million for Noble Americas Energy Solutions. It will be paid an additional $248 million for the US unit’s working capital.

Calpine describes itself as America’s largest generator of electricity from natural gas and geothermal resources. In July it its third quarterly loss in a row.
