Constitution Pipeline slips in-service date 6-12 mos!!! Cabot's stock drops 11%

I'm trying to understand why Cabot's stock price took a
staggering 11% drop (from $40 to $35.6) in late Feb
leading up to their 4Q13 earnings call.

It's very strange, because Cabot by the numbers looks good.
The Street lists it as a BUY. Everything is great!

The only thing I can figure is that the reason I can figure is
thy announced that Constitution Pipeline schedule slipped
the in-service date from March 2015 to late '15 or early '16.
(6 months to a year). This is the first time I've seen them change
the "March 2015" date since the open season announcement.

 Whoops. Slipped again, according to the Swift Affidavit,
to "in-service by December 2nd of 2016", that's LATE 2nd half 2016.

Woah. Now George Stark says the next pipeline won't be online for "another 5 years".
Now is March 2015. This means March 2020??! What tha...?
