The Previously Announced KOG Deal For Liberty Resources Has Closed; Pricier Than Initial Numbers?

It's a little bit difficult for me to sort out exactly how much this deal cost KOG. From the press release:

• The announced purchase price for the asset package was $660 million. Post-closing adjustments were $52 million, including $31 million in working capital items and $21 million of cash flow adjustments to reflect the acquisition's March 1, 2013 effective date.  The Company paid an additional $20 million for acquisition costs associated with increased working interests acquired by Liberty subsequent to the effective date.

If I interpret that correctly:

• $660 million was the announced price
• an additional $52 million to reflect the acquisition's effective date
• an additional $20 million for acquisition costs

$660 + $72 = $732 million, making this pricey acquisition even pricier.  But again, I may be misinterpreting these numbers.

Mike Filloon used $660 million in his calculations when he looked at the deal: KOG's purchase of Liberty Resources could make or break its 2013.

Looking at share prices today, it's a bit difficult to see how the market views this new information. Maybe next week we will see some clarity. KOG is down 2.4% for the day; OAS is down 0.12%. CLR is flat, and WLL is down 1%.
