GOING CONCERN	GOING CONCERN The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business for the twelve-month period following the date of issuance of these condensed consolidated financial statements. Our ability to sustain our business in the future will depend on sufficient oil and natural gas operating cash flows, which are highly sensitive to potentially volatile oil and natural gas prices, sufficient contract drilling operating cash flows, which are subject to potentially large changes in demand, and sufficient future land investment segment proceeds and distributions from the Kukio Resort Land Development Partnerships, the timing of which are both highly uncertain and not within Barnwell’s control. A sufficient level of such cash inflows are necessary to fund discretionary oil and natural gas capital expenditures, which must be economically successful to provide sufficient returns, as well as fund our non-discretionary outflows such as oil and natural gas asset retirement obligations and ongoing operating and general and administrative expenses. We have experienced a trend of losses and negative operating cash flows in recent years. Due to the additional impacts of the COVID-19 pandemic, we now face a greater uncertainty about our cash inflows as described above, which in turn leads to substantial doubt regarding our ability to make the required discretionary cash outflows for the capital expenditures necessary to convert our proved undeveloped reserves to proved developed reserves. Furthermore, because of the greater uncertainty about our cash inflows described above, there is substantial doubt about our ability to fund our non-discretionary cash outflows and thus substantial doubt about our ability to continue as a going concern for one year from the date of the filing of this report. The Company is investigating potential sources of funding, including non-core oil and natural gas property sales, however, no probable sources of such funding have yet been secured. Alternatively, management has the ability to sell its corporate office on the 29th floor of a commercial office building in downtown Honolulu, Hawaii, to generate liquidity without impacting operations significantly, in order to mitigate the substantial doubt about our ability to continue as a going concern. However, the Company’s ability to sell its corporate office at an appropriate time or for a sufficient price is outside of the Company's control and is therefore not probable. Because of this uncertainty as well as uncertainties regarding the potential duration and depth of the impacts of the COVID-19 pandemic on our business as described above, substantial doubt about our ability to continue as a going concern for one year from the date of the filing of this report exists. These financial statements do not include any adjustments that might result from the outcome of these uncertainties.

GOING CONCERN

The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business for the twelve-month period following the date of issuance of these condensed consolidated financial statements.

Our ability to sustain our business in the future will depend on sufficient oil and natural gas operating cash flows, which are highly sensitive to potentially volatile oil and natural gas prices, sufficient contract drilling operating cash flows, which are subject to potentially large changes in demand, and sufficient future land investment segment proceeds and distributions from the Kukio Resort Land Development Partnerships, the timing of which are both highly uncertain and not within Barnwell’s control. A sufficient level of such cash inflows are necessary to fund discretionary oil and natural gas capital expenditures, which must be economically successful to provide sufficient returns, as well as fund our non-discretionary outflows such as oil and natural gas asset retirement obligations and ongoing operating and general and administrative expenses.

We have experienced a trend of losses and negative operating cash flows in recent years. Due to the additional impacts of the COVID-19 pandemic, we now face a greater uncertainty about our cash inflows as described above, which in turn leads to substantial doubt regarding our ability to make the required discretionary cash outflows for the capital expenditures necessary to convert our proved undeveloped reserves to proved developed reserves. Furthermore, because of the greater uncertainty about our cash inflows described above, there is substantial doubt about our ability to fund our non-discretionary cash outflows and thus substantial doubt about our ability to continue as a going concern for one year from the date of the filing of this report.

The Company is investigating potential sources of funding, including non-core oil and natural gas property sales, however, no probable sources of such funding have yet been secured.
