On an interim basis, Halkyard's responsibilities will be assumed by other members of the company's senior management team, including Chairman, CEO and President Gary Loveman.
"We have an experienced team of senior leaders who will oversee the finance functions and ensure that we maintain our momentum as we execute on our growth plans. We have made significant progress in improving our operations and balance sheet, and will ensure these efforts continue," Loveman said. "Jonathan has played an important role in managing the company's financial position and in helping us return to the public equity markets earlier this year. We thank him for his service and wish him well in his future endeavors."
During the past several years, the company has completed multiple exchange offers and other transactions that have reduced outstanding debt by more than $5 billion and financings that have extended the company's maturity profile and bolstered its liquidity.
