There is a difference in price because Friday was a holiday and different brokers bought at different times leading into March 29. That is why there is such a disparity. You could have prices range from $3.71 to $3.99. The market opened on Thursday at $3.90 and fell to $3.71 before closing at $3.99.
Let's see, back when Maggie became FTR Czar if you owned 10k shares your dividend of $.25 would have been $2,500 and you would have gotten 200 more shares.
Now you would receive $1000 and gotten 264 more shares at $3.79 each.
The above math is something sage seems to like -- the higher the DRIP share count the more he thinks is coming in.
