Basis of Presentation and Significant Accounting Policies

NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

 

The accompanying unaudited consolidated financial statements of Houston American Energy Corp., a Delaware corporation (the “Company”), have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q. They do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for a complete financial presentation. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation, have been included in the accompanying unaudited consolidated financial statements. Operating results for the periods presented are not necessarily indicative of the results that may be expected for the full year.

 

These unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes, which are included as part of the Company’s Form 10-K for the year ended December 31, 2015.

 

Going Concern

 

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of these consolidated financial statements. The Company has incurred continuing losses, negative operating cash flow and declining cash balances since 2011, including negative operating cash flow of $1,023,200 for the nine months ended September 30, 2016. These conditions, together with continued low oil and natural gas prices and financial commitments the Company has made relative to its Colombian properties, raise substantial doubt as to the Company’s ability to continue as a going concern. These financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

 

To address these concerns, the Company may seek additional financing or may consider divestiture of certain assets. There can be no assurance that the Company will be successful in its efforts.

 

Consolidation

 

The accompanying consolidated financial statements include all accounts of the Company and its subsidiaries (HAEC Louisiana E&P, Inc., HAEC Oklahoma E&P, Inc. and HAEC Caddo Lake E&P, Inc.). All significant inter-company balances and transactions have been eliminated in consolidation.

 

Accounting Principles and Use of Estimates

 

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. In preparing financial statements, management makes informed judgments and estimates that affect the reported amounts of assets and liabilities as of the date of the financial statements and affect the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management reviews its estimates, including those related to such potential matters as litigation, environmental liabilities, income taxes and the related valuation allowance, determination of proved reserves of oil and gas and asset retirement obligations. Changes in facts and circumstances may result in revised estimates and actual results may differ from these estimates.

 

Concentration of Credit Risk

 

Financial instruments that potentially subject the Company to a concentration of credit risk include cash, cash equivalents and any marketable securities. The Company had cash deposits of $494,077 in excess of the FDIC’s current insured limit on interest bearing accounts of $250,000 as of September 30, 2016. The Company has not experienced any losses on its deposits of cash and cash equivalents.

  

Loss per Share

 

Basic loss per share is computed by dividing net loss available to common shareholders by the weighted average common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares that then shared in the earnings of the Company. The Company’s only outstanding potentially dilutive securities are options and warrants. Using the treasury stock method, outstanding ‘in-the-money’ options would have increased our diluted weighted average shares outstanding by approximately 55,600 shares for the three and nine months ended September 30, 2016 and by approximately 55,600 shares for the three and nine months ended September 30, 2015; however, due to losses during these periods, these options were excluded from the diluted earnings per share calculation because their effect would have been anti-dilutive.

 

Subsequent Events

 

The Company has evaluated all transactions from September 30, 2016 through the financial statement issuance date for subsequent event disclosure consideration.

 

Recent Accounting Pronouncements

 

No accounting standards or interpretations issued recently are expected to a have a material impact on our consolidated financial position, operations or cash flows.

Oil and Gas Properties

NOTE 3 – OIL AND GAS PROPERTIES

 

During the nine months ended September 30, 2016, the Company invested $92,217 for the development of oil and gas properties, consisting of (1) preparation and evaluation costs in Colombia of $67,966, and (2) costs on U.S. properties of $24,251. Of the amount invested, the Company capitalized $24,251 to oil and gas properties subject to amortization, and $67,966 to oil and gas properties not subject to amortization.

 

During the nine months ended September 30, 2015, the Company disposed of a portion of its interest in three non-producing domestic prospects for proceeds of $56,705. Proceeds received from disposal of such interests were accounted for as a reduction in capitalized cost of oil and gas properties.

 

Geographical Information

 

The Company currently has operations in two geographical areas, the United States and Colombia. Revenues for the nine months ended September 30, 2016 and long lived assets (net of depletion, amortization, and impairments) as of September 30, 2016 attributable to each geographical area are presented below:

Stock-Based Compensation Expense

NOTE 4 – STOCK-BASED COMPENSATION EXPENSE

 

The Company periodically grants options to employees, directors and consultants under the Company’s 2005 Stock Option Plan and the Company’s 2008 Equity Incentive Plan (together, the “Plans”). The Company is required to make estimates of the fair value of the related instruments and recognize expense over the period benefited, usually the vesting period.

 

Stock Option Activity

 

In March 2016, options to purchase an aggregate of 20,000 shares were granted to non-employee directors. The options were granted in connection with service on an ad hoc board committee and vest on the earlier of August 15, 2016, the termination of the committee or termination of service on the committee due to death or disability. The options have a five-year life and an exercise price of $0.1982 per share. The options were valued on the date of grant at $2,896 using the Black-Scholes option-pricing model with the following parameters: (1) risk-free interest rate of 1.49%; (2) expected life in years of 4.99; (3) expected stock volatility of 106.95%; (4) expected dividend yield of 0%; and (5) forfeiture rate of 15.22%. The Company determined the options qualify as ‘plain vanilla’ under the provisions of SAB 107 and the simplified method was used to estimate the expected option life.

 

In June 2016, options to purchase an aggregate of 800,000 shares were granted to non-employee directors. The options, which included a one-time supplemental grant to purchase an aggregate of 600,000 shares, were granted in connection with service on the board of directors. 200,000 of the options granted to non-employee directors vested 20% on the grant date and vest as to the remaining 80% nine months from the grant date, have a ten-year life and have an exercise price of $0.2201 per share. Those option grants were valued on the date of grant at $32,640 using the Black-Scholes option-pricing model with the following parameters: (1) risk-free interest rate of 1.26%; (2) expected life in years of 5.28; (3) expected stock volatility of 108.5%; (4) expected dividend yield of 0%; and (5) forfeiture rate of 15.01%. 600,000 of the options granted to non-employee directors vest (i) 50% on the earlier of June 7, 2017 or the day preceding the next annual shareholders meeting at which directors are elected, (ii) 50% on the earlier of June 7, 2018 or the day preceding the second annual shareholders meeting (after the grant date) at which directors are to be elected, and (iii) in the event that the Company consummates a transaction(s) (after the option grant date) in the nature of a sale of shares of equity securities for cash or assets resulting in a net addition(s) to the Company’s stockholders’ equity of not less than $2 million, all unvested options vest in full. Those options have a ten-year life and have an exercise price of $0.2201 per share. Those option grants were valued on the date of grant at $83,421 using the Black-Scholes option-pricing model with the following parameters: (1) risk-free interest rate of 1.26% (2) expected life in years of 5.28, and (3) expected stock volatility of 108.5%. The Company determined the option qualifies as ‘plain vanilla’ under the provisions of SAB 107 and the simplified method was used to estimate the expected option life.

Share-Based Compensation Expense

 

During the three and nine months ended September 30, 2016, the Company recognized $37,805 and $99,006, respectively, of stock compensation expense attributable to the amortization of unrecognized stock-based compensation.

 

As of September 30, 2016, total unrecognized stock-based compensation expense related to non-vested stock options was $157,804. The unrecognized expense is expected to be recognized over a weighted average period of 1.36 years and the weighted average remaining contractual term of the outstanding options and exercisable options at September 30, 2016 is 6.6 years and 5.46 years, respectively.

Going Concern

Going Concern

 

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of these consolidated financial statements. The Company has incurred continuing losses, negative operating cash flow and declining cash balances since 2011, including negative operating cash flow of $1,023,200 for the nine months ended September 30, 2016. These conditions, together with continued low oil and natural gas prices and financial commitments the Company has made relative to its Colombian properties, raise substantial doubt as to the Company’s ability to continue as a going concern. These financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.

 

To address these concerns, the Company may seek additional financing or may consider divestiture of certain assets. There can be no assurance that the Company will be successful in its efforts.

( custom:GoingConcernPolicyTextBlock [Extension] )  
Consolidation

Consolidation

 

The accompanying consolidated financial statements include all accounts of the Company and its subsidiaries (HAEC Louisiana E&P, Inc., HAEC Oklahoma E&P, Inc. and HAEC Caddo Lake E&P, Inc.). All significant inter-company balances and transactions have been eliminated in consolidation.

( us-gaap:ConsolidationPolicyTextBlock )  
Accounting Principles and Use of Estimates

Accounting Principles and Use of Estimates

 

The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. In preparing financial statements, management makes informed judgments and estimates that affect the reported amounts of assets and liabilities as of the date of the financial statements and affect the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management reviews its estimates, including those related to such potential matters as litigation, environmental liabilities, income taxes and the related valuation allowance, determination of proved reserves of oil and gas and asset retirement obligations. Changes in facts and circumstances may result in revised estimates and actual results may differ from these estimates.

( us-gaap:UseOfEstimates )  
Concentration of Credit Risk

Concentration of Credit Risk

 

Financial instruments that potentially subject the Company to a concentration of credit risk include cash, cash equivalents and any marketable securities. The Company had cash deposits of $494,077 in excess of the FDIC’s current insured limit on interest bearing accounts of $250,000 as of September 30, 2016. The Company has not experienced any losses on its deposits of cash and cash equivalents.

( us-gaap:ConcentrationRiskCreditRisk )  
Loss per Share

Loss per Share

 

Basic loss per share is computed by dividing net loss available to common shareholders by the weighted average common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares that then shared in the earnings of the Company. The Company’s only outstanding potentially dilutive securities are options and warrants. Using the treasury stock method, outstanding ‘in-the-money’ options would have increased our diluted weighted average shares outstanding by approximately 55,600 shares for the three and nine months ended September 30, 2016 and by approximately 55,600 shares for the three and nine months ended September 30, 2015; however, due to losses during these periods, these options were excluded from the diluted earnings per share calculation because their effect would have been anti-dilutive.

( us-gaap:EarningsPerSharePolicyTextBlock )

The Company has evaluated all transactions from September 30, 2016 through the financial statement issuance date for subsequent event disclosure consideration.
