ATP Oil & Gas Corp. saw relatively flat revenues from 2007 to 2008 but was able to grow net income over that period by reducing selling, general and administrative costs as a percentage of revenues. While the company has high debt levels, it has been effective at collecting receivables, with days receivables outstanding of 69 days in 2008. The financial statements show that from 2006 to 2009, the company invested heavily in property, plant and equipment but was able to fund much of that through debt issuances and proceeds from asset sales.
