My understanding is that you will have to pay 49.87 for each share of stock you buy. The incentive at the offering time was that the current price in the future could be higher than 49.87. Make sure you clear that with E-Trade.
You have 1000 shares. You can convert into 20,051 shares. At 49.87 each your cost will be $999,943.37.
I could be wrong....I hope so. Let me know how it works out.
