Granulocytes, specifically neutrophils, help the body fight bacterial infections. The number of granulocytes in the body usually increases when there is a serious infection. People with a lower number of granulocytes are more likely to develop bad infections more often.
Congrats on a sick trade. If the buyout happens before the options expiration, you can exercise your options for stock, purchase the stock at $28.00, and sell the shares for $40.00 and make $12.00 per share (less the price of the options). Realistically, the value of the call option will go up to $12.00+ and you can just sell the option.
Buyout auction is an auction with an additional set price (the 'buyout' price) that any bidder can accept at any time during the auction, thereby immediately ending the auction and winning the item. If no bidder chooses to utilize the buyout option before the end of bidding the highest bidder wins and pays their bid.
