Results of Operations

Based on the factors discussed below, the net loss attributable to common shareholders for the year ended June 30, 2017, decreased by $8.1 million, to a net loss of $14.7 million or $(0.68) per basic and diluted share in 2017 from a net loss of $22.8 million, or $(1.09) per basic and diluted share in 2016.

Comparison for Fiscal Years 2017 and 2016

Revenues. There were no revenues for the years ended June 30, 2017 and 2016.

Depreciation . Depreciation decreased 56% or $61,000 from fiscal 2016 to fiscal 2017. Depreciation expense was $48,000 and $109,000 in the years ended June 30, 2017 and 2016, respectively. The decrease is primarily attributed to no asset additions in the current year and a portion of assets used in the prior year being fully depreciated in the current year.

General, Administrative and Other Operating Expenses . Our general, administrative and other operating expenses were $13.6 million and $8.4 million for the years ended June 30, 2017 and 2016, respectively. This represents an increase of 63% or $5.2 million from fiscal 2016 to fiscal 2017. The $5.2 million increase in expense was attributable mainly to an increase in contractor expense by $4.2 million due to operations in Guinea. Also contributing to the increased expense were increased salary expense by $0.6 million due to increased staff at the corporate office as well as increased expense for travel and other employee expenses by $0.5 million.

Full-Cost ceiling test write-down . During fiscal year ended June 30, 2017, we had a full-cost ceiling test write-down of $5.2 million. During fiscal year ended June 30, 2016, we fully impaired our unproved oil and gas properties, which totaled $14.3 million.

Loss from Continuing Operations . Primarily as a result of the increase in general and administrative expenses of $5.2 million, offset by the decrease in the full-cost ceiling test write-down of $9.1 million, our loss from operations decreased by $3.9 million from $22.8 million for the year ended June 30, 2016 to $18.9 million for the year ended June 30, 2017.

The foregoing information is preliminary and unaudited and may be subject to change in the Report when filed.
