|Analysis of Changes in Proved Reserves
The following table sets forth information regarding the Company's estimated proved oil and gas reserve quantities, all of which are included in assets held for sale in the accompanying consolidated balance sheets as of June 30, 2016 and 2015. The Company emphasizes that reserve estimates are inherently imprecise and that estimates of new discoveries and undeveloped locations are more imprecise than estimates of established producing oil and gas properties. Accordingly, these estimates are expected to change as economic conditions change and new information becomes available.

The following table summarizes the resulting prices used for proved reserves for the fiscal years ended:

The following table presents the standardized measure of discounted future net cash flows related to proved oil and gas reserves for the United States cost center only:
|Standardized Measure of Oil and Gas - Changes in Standardized Measure of Discounted Future Net Cash Flows
A summary of changes in the standardized measure of discounted future net cash flows is as follows:
(1) The increase in cash flows from the net change in income taxes in fiscal year 2015 represents the decrease in future income taxes as a result of the elimination of cash flows from PUD reserves.
(2) For fiscal year 2016, there was an $11.0 million downward revision in reserve value due to the net change in prices and production costs. This change was the result of the steep decline in the WTI price, the benchmark oil price for sale of the Company's crude oil.
(3) The downward revision of $5.8 million relates to the reduction of 643 Mbbls of proved developed non-producing reserves as a result of the elimination of the Company's workover program.
