Pretty simple concept. UAL had several years of "losses". The government doesn't give you money when you have "negative income", but you can use those loses to mitigate future taxes (if you lost one mill this year and made one mil next, you'd pay no taxes since your net was 0). The "credit" for "negative taxes" owed is carried on the balance sheet until it is offset by "positive taxes" owed.
In short, UAL will pay no taxes on the money they made this Q, but the total credit for "negative taxes" will be reduced on the balance sheet by the amount the would have owed without losses in previous years.
The credits don't last forever (5 years?) and are lost if the company has a "change of control" (to prevent a company from buying a BK company just for it's tax credits, this was an issue when AMR bought TWA). AMR will also have the same accounting "gimick" from their losses in the early 2000's
I agree with you and I understand the concept of net loss carryforwards.
My question is why UA and DL have shown this phantom tax they won't pay (due to the NOLs) yet AMR has not done the same thing on its quarterly financials?
AMR has shown profits for several consecutive quarters yet has completely omitted any non-cash income tax charge against those earnings.
