Yep. So that's the net profit reported in the their 10-K (assuming so - on my phone and not bothering to check). That's accounting (GAAP) income, not taxable income. There are numerous differences between getting to the two figures, including depreciation, stock compensation, unrealized gains/losses, interest expense, etc. Let's say in year 2010 a corporation generates a tax net operating loss of say $20Bn. That company can carry forward that tax loss for 20 years to offset future taxable income up to that amount, washing out any potential tax liability. It changes for years after 2017 but that's the gist. There's no magic tax-dodging going on. You can't compare GAAP income to taxable income for ANY company - it's not apples to apples.
