Other than the obligations associated with the acquisition and exploration of our oil and gas leases disclosed elsewhere in this report, we have no material future contractual obligations as of May 31, 2013.
During the period from June 2012, through February 2013, we sold 4,405,667 shares of our common stock to twenty eight accredited investors at a price of $1.20 per share. Gross proceeds from these private placements totaled $5,286,800. We paid $164,038 in finder’s fees in connection with the sale of these shares.
During December 2011, we retired $70,000 in non-interest bearing notes payable to an unrelated party. In exchange for the notes, we issued 23,334 investment units to the noteholder. The investment units were priced at $3.00 each and consisted of one share of our common stock, and one stock purchase warrant. Each stock purchase warrant entitles the holder to purchase one share of our common stock at a price of $4.50 per share until November 5, 2013.
During May 2011, we sold 120,000 investment units. The investment units were priced at $3.00 each and consisted of one share of our common stock and one stock purchase warrant. Each stock purchase warrant entitles the holder to purchase one share of our common stock at a price of $4.50 per share until April 15, 2013. Proceeds from the private placement totaled $360,000, all of which were paid in cash. We paid $2,400 in finder’s fees in connection with the sale of the units. Our Chief Executive Officer acquired 50,000 investment units in this private placement.
During April 2011, we sold 390,000 investment units at a price of $3.00 per unit. Each unit consisted of one share of our common stock and one warrant. Each warrant entitles the holder to purchase one share of our common stock at a price of $4.50 per share until April 1, 2013. Proceeds from the private placement totaled $1,170,000, all of which was paid in cash. We paid $46,800 in finder's fees in connection with the sale of the units.
During December 2010, we sold 86,870 investment units at a price of $2.30 per unit. Each unit consisted of one share of our common stock and one warrant. Each warrant entitles the holder to purchase one share of our common stock at a price of $3.50 per share until December 29, 2012. Proceeds from the private placement totaled $191,100 (net of $8,700 in fees) of which $166,100 was paid in cash and $25,000 was a repayment of a loan.
In connection with the San Miguel Farmout Agreement, we obtained $400,000 in temporary financing from our largest shareholder. This financing was subject to a non-interest bearing demand note payable. The entire $400,000 note balance was repaid from proceeds of a private placement of investment units during April 2011.
We believe our plan of operations, exclusive of costs associated with the KGP or other acquired assets, will require from $1,500,000 to $2,000,000 in financing over the twelve-month period ending June 30, 2014 to cover general, administrative, and other costs.
If we are unable to raise the financing we need, our business plan may fail and our stockholders could lose their investment. There can be no assurance that we will be successful in raising the capital we require, or that if the capital is offered, it will be subject to terms we consider acceptable. Investors should be aware that even if we are able to raise the funds we require, there can be no assurance that we will succeed in our acquisition, exploration or production plans and we may never be profitable.
As of July 10, 2013 we did not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future material effect on our financial condition, changes in financial condition, results of operations, liquidity or capital resources.
Critical Accounting Policies and Estimates
Measurement Uncertainty
The preparation of consolidated financial statements in conformity with US GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We regularly evaluate estimates and assumptions. We base our estimates and assumptions on current facts, historical experience and various other factors we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced by us may differ materially and adversely from our estimates. To the extent there are material differences between the estimates and the actual results, future results of operations will be affected. The most significant estimates with regard to our consolidated financial statements relate to carrying values of oil and gas properties, the estimate of proved oil and gas reserves and related present value estimates of future net cash flows, asset retirement obligations, the valuation of goodwill, determination of fair values of stock-based transactions, deferred income tax rates, and environmental risks and exposures.
