This is what I found about the "D"

"As the question states, a company that has undergone a reverse stock split often gets the letter "D" attached to the end of its ticker symbol. This letter is used to designate a company that is undergoing a stock split of some sort (most often a reverse split), or some form of corporate reorganization. This letter is generally attached to the end of the ticker for approximately 20 trading days before it's removed. "
