AerCap is buying AIG's International Lease Finance operations. From the WSJ, "The acquisition will make AerCap the world's largest plane lessor, with roughly 1,300 planes."
"AerCap is acquiring ILFC at "a significant discount to book value" thanks partly to accounting rules applied to the deal. This, combined with AerCap's Irish tax domicile, makes the deal highly attractive. He said that after the ILFC's portfolio revaluation, older models account for only about 15% of its value. The large number of older planes in ILFC's portfolio has been one uncertainty hanging over the company."
"After the deal completion, slated for the second quarter of next year, AIG will be the single largest shareholder in AerCap, with approximately 46% of the combined company."
I'm a holder of a few shares of AerCap (AER) since June '09.
