I beg to differ. While it's true that we don't know precisely how many shares each employee will get, there are a lot of numbers to which we already have the answer.
Currently, there are about 197 million shares of LCC (US Airways) outstanding. Each of those shares will be cancelled and replaced by one share of new AA on Monday. LCC closed today at about $22.55/sh
New AA will issue about 507 million additional shares of new stock. We already know that the APA pilots will get 13.5% of that, or about 68 million shares. At today's price, the APA will split about $1.5 billion. We know that the APFA will get 3% of that new stock, or about 15.2 million shares, worth an estimated $343 million. We know that the TWU will get 4,8% of that new stock, or about 24.3 million shares, worth an estimated $550 million. The agents, support staff and management (lower-level management that isn't getting big chunks of stock) will split 2.3% of that new stock, worth probably about $263 million or so.
The unsecured creditors will get much of the remaining stock, and, last, the current shareholders of old AAMRQ will divide up what's left. Some analysts are estimating that the holders of old AAMRQ might end up getting $5 billion or so worth of new AA stock. How much they ultimately get is really up in the air.
