Summary Pro Forma Combined
Oil, Natural Gas and Natural Gas Liquids
Reserve Data
 
The following tables set forth summary pro forma information with respect to Vanguard's pro forma combined estimated net proved and proved developed natural gas, oil and natural gas liquids reserves as of December 31, 2011. This pro forma information gives effect to the ENP Merger, the Permian Basin Acquisition I, the Arkoma Basin Acquisition and the Rockies Acquisition as if they occurred on January 1, 2011. Future exploration, exploitation and development expenditures, as well as future commodity prices and service costs, will affect the reserve volumes attributable to the acquired properties and the standardized measure of discounted future net cash flows.
 
Estimated changes in the quantities of natural gas, oil and natural gas liquids reserves for the year ended December 31, 2011 are as follows:

(a)
Represents the reduction in future net cash flows and discounted future net cash flows relating to the properties acquired in the Arkoma Basin Acquisition primarily related to locations where Vanguard does not plan to undertake development activities. The adjustments also include the elimination of future tax expense since Vanguard is not a taxable entity.
(b)
The pro forma standardized measure includes Vanguard, the Permian Basin Acquisition I, the Arkoma Basin Acquisition and the Rockies Acquisition.

For the December 31, 2011 calculations in the preceding table, estimated future cash inflows from estimated future production of proved reserves were computed using the average oil and natural gas price based upon the 12-month unweighted average first-day-of-the-month price ("12-month average price), adjusted for quality, transportation fees and a regional price differential. The 12-month average prices are as follows:

 
 
Vanguard Historical
 
Arkoma Basin Acquisition
 
Rockies Acquisition
Oil (Price/Bbl)
 
$
96.24

 

 
$
92.71

Natural Gas (Price/Mcf)
 
$
4.12

 
$
3.90

 
$
3.93



We may receive amounts different than the standardize measure of discounted cash flow for a number of reasons, including price changes and the effects of our hedging activities.










The following are the principal sources of change in the pro forma combined standardized measure of discounted future net cash flows for the year ended December 31, 2011 (in thousands):
