Supplemental Disclosures about Oil and Natural Gas Producing Properties (unaudited)

Costs incurred for oil and natural gas property acquisition, exploration and development activities

The following table summarizes costs incurred and capitalized in oil and natural gas property acquisition, exploration and development activities. Property acquisition costs are those costs incurred to lease property, including both undeveloped leasehold and the purchase of reserves in place. Exploration costs include costs of identifying areas that may warrant examination and examining specific areas that are considered to have prospects containing oil and natural gas reserves, including costs of drilling exploratory wells, geological and geophysical costs and carrying costs on undeveloped properties. Development costs are incurred to obtain access to proved reserves, including the cost of drilling. Exploration and development costs also include amounts incurred due to the recognition of asset retirement obligations of $86,384 and $43,922 during the years ended June 30, 2019 and 2018, respectively.

Estimated Net Quantities of Proved Oil and Natural Gas Reserves

The following estimates of the net proved oil and natural gas reserves of our oil and gas properties located entirely within the United States of America are based on evaluations prepared by third-party reservoir engineers. Reserve volumes and values were determined under the method prescribed by the SEC for our fiscal years ended June 30, 2019 and 2018, which requires the application of the previous 12 months unweighted arithmetic average first-day-of-the-month price, and current costs held constant throughout the projected reserve life, when estimating whether reserve quantities are economical to produce.

Proved oil and natural gas reserves are estimated quantities of crude oil, natural gas and natural gas liquids that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed oil and natural gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment and operating methods. There are uncertainties inherent in estimating quantities of proved oil and natural gas reserves, projecting future production rates, and timing of development expenditures. Accordingly, reserve estimates often differ from the quantities of oil and natural gas that are ultimately recovered.

Estimated quantities of proved oil and natural gas reserves and changes in quantities of proved developed and undeveloped reserves for each of the periods indicated were as follows:



	Crude Oil (Bbls)		Natural Gas Liquids (Bbls)		Natural Gas (Mcf)	BOE
Proved developed and undeveloped reserves:
June 30, 2017	8,372,150		1,686,228		—	10,058,378
Revisions of previous estimates (a)	369,971		(315,090	)	—	54,881

Sales of minerals in place	—		—		—	—
Production (sales volumes)	(626,879	)	(112,089	)	—	(738,968	)
June 30, 2019	7,615,731		1,364,761		—	8,980,492
Proved developed reserves:
June 30, 2017	6,617,389		1,332,803		—	7,950,192
June 30, 2018	6,291,850		993,741		—	7,285,591
June 30, 2019	6,273,907		1,124,302		—	7,398,209
Proved undeveloped reserves:
June 30, 2017	1,754,761		353,425		—	2,108,186
June 30, 2018	1,798,340		284,031		—	2,082,371
June 30, 2019	1,341,824		240,459		—	1,582,283

(a) The positive crude oil revision resulted from better production performance during fiscal 2018. The negative NGL revision results primarily from lower expectations for ultimate NGL recoveries from the plant based on production data subsequent to the commencement of plant production.

(b) The positive crude oil and NGL revisions were the result of improvements in well and NGL plant performance respectively.

Standardized Measure of Discounted Future Net Cash Flows

Future oil and natural gas sales and production and development costs have been estimated using prices and costs in effect at the end of the years indicated, as required by ASC 932, Extractive Activities - Oil and Gas ("ASC 932"). ASC 932 requires that net cash flow amounts be discounted at 10%. Future production and development costs are computed by estimating the expenditures to be incurred in developing and producing our proved oil and natural gas reserves and asset retirement obligations assuming continuation of existing economic conditions. Future income tax expenses are computed by applying the appropriate period-end statutory tax rates to the future pretax net cash flow relating to our proved oil and natural gas reserves, less the tax basis of the related properties. The future income tax expenses do not give effect to tax credits, allowances, or the impact of general and administrative costs of ongoing operations relating to the Company's proved oil and natural gas reserves. Changes in the demand for oil and natural gas, inflation, and other factors make such estimates inherently imprecise and subject to substantial revision. The table below should not be construed to be an estimate of the current market value of our proved reserves.

The standardized measure of discounted future net cash flows related to proved oil and natural gas reserves as of June 30, 2019 and 2018 are as follows:



	As of June 30,
	2019			2018
Future cash inflows	$	524,037,200		$	521,533,765
Future production costs and severance taxes	(208,539,679		)	(228,478,119		)
Future development costs	(18,395,252		)	(22,213,269		)
Future income tax expenses	(55,881,997		)	(50,810,883		)
Future net cash flows	241,220,272			220,031,494
10% annual discount for estimated timing of cash flows	(114,488,230		)	(101,073,080		)
Standardized measure of discounted future net cash flows	$	126,732,042		$	118,958,414

Future cash inflows represent expected revenues from production of period-end quantities of proved reserves based on the previous 12 months unweighted arithmetic average first-day-of-the-month commodity prices for each year and reflect adjustments for lease quality, transportation fees, energy content and regional price differentials.



	For the Years Ended June 30,
	2019			2018
	Oil (Bbl)		Gas (MMBtu)	Oil (Bbl)		Gas (MMBtu)
NYMEX prices used in determining future cash flows	$	61.62	n/a	$	57.50	n/a

There were no natural gas reserves in 2019 and 2018. The NGL prices utilized for future cash inflows were based on historical prices received, where available. For the Delhi NGL plant, we utilized historical prices for the expected mix and net pricing of natural gas liquid products projected to be produced by the plant.

A summary of the changes in the standardized measure of discounted future net cash flows applicable to proved crude oil, natural gas liquids, and natural gas reserves is as follows:
