seems like you are missing the entire structure of the deal.
CMLP is being merged into (acquired by) NRGM.
CMLP units convert at a fixed ratio to NRGM units.
Therefore any change in NRGM's price necessarily is reflected in that of CMLP (since the exchange ratio is fixed).
Because when the merger takes place. CMLP unit holders are going to receive 1.07 units of NRGM for every unit they own of CMLP. CMLP will go away. CMLP holder are also going to receive a special distribution of about a $1.03. So their unit prices are connected.
Thank you - but still have a question - what happens to NRGY? I have actually owned CMLP and NRGY for a long time, and I read the merger news, but didn't pick out that NRGM was the surviving company - Then will NRGY stay around?
