CTL isn't valued at $16B. That's only the market capitalization of its common shares outstanding.
LVLT market cap = $19.4B
LVLT assets = $24.1B (as of FYE15)
CTL market cap = $16.5B
CTL assets = $47.6B (as of FYE15)
This deal's ~$10B cash + ~$15B stock (edit: based on diff. article from wsj[0] It's $34B if you include $10B in LT debt.) CTL needs to raise cash and issue/buy-back shares. Lots of options, but I'm sure they already have creditors lined up.On an unrelated note, CTL has $20B in goodwill on its balance sheet. Wow...
