How many FTD's are there in Teco that would indicate naked short shares?

This is called a “buy–in,” and it is supposed to maintain the total number of shares in the market place equal to the number of shares the company has issued.
Market makers have special exemptions from the rules: they are allowed to carry a naked short for up to twenty–one trading days before they have to borrow a share. When the share is not borrowed in the allotted time and a buy–in does not occur, and they rarely do, the naked short becomes a fail–to–deliver (of the borrowed share).
