2. Basis of preparation

(a) Statement of compliance

These condensed consolidated interim financial statements have been prepared in accordance with International Financial Reporting Standard (“IFRS”) as issued by the International Accounting Standards Board ("IASB"). These condensed consolidated interim financial statements do not include all of the necessary information required for full annual financial statements in accordance with IFRS and should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2020.

These condensed consolidated interim financial statements were approved and authorized for issuance by the Board of Directors on August 16, 2021.

(b) Functional and presentation currency

These condensed consolidated interim financial statements are presented in Canadian dollars, which is the Company’s functional currency.

(c) Basis of measurement

These financial statements have been prepared on the historical cost basis except for:

(d) Basis of consolidation

For financial reporting purposes, subsidiaries are defined as entities controlled by the Company. The Company controls an entity when it has power over the investee; it is exposed to, or has rights to, variable returns from its involvement with the entity; and it has the ability to affect those returns through its power over the entity.

2. Basis of preparation (continued)

In instances where the Company does not hold a majority of the voting rights, further analysis is performed to determine whether or not the Company has control of the entity. The Company is deemed to have control when, according to the terms of the shareholder’s and/or other agreements, it makes most of the decisions affecting relevant activities.

Theses consolidated financial statements include the accounts of the Company and its subsidiary Drosrite International LLC. Drosrite International LLC is owned by a member of the Company’s key management personnel and close member of the CEO and controlling shareholder’s family and is deemed to be controlled by the Company. All significant transactions and balances between the Company and its subsidiary have been eliminated upon consolidation.

3. Significant accounting judgments, estimates and assumptions

The significant judgments, estimates and assumptions applied by the Company’s in these condensed consolidated interim financial statements are the same as those applied by the Company in its audited annual financial statements as at and for the year ended December 31, 2020.

The COVID-19 pandemic continues to evolve as vaccination campaigns are currently underway in Canada and other countries in which the Company operates while more contagious variants of the virus have evolved. The financial effect of the pandemic is still uncertain at this time as is the Company’s business continuity plans and other mitigating measures. Estimates of the length and seriousness of these developments is therefore subject to significant uncertainty, and accordingly estimates of the extent to which the COVID-19 pandemic may materially and adversely affect the Company’s operations, financial results and condition in future periods are also subject to significant uncertainty.

Therefore, uncertainty about judgments, estimates and assumptions made by management during the preparation of the Company’s interim consolidated financial statements related to potential impacts of the COVID-19 pandemic on revenue, expenses, assets, liabilities, and note disclosures could result in a material adjustment to the carrying value of the asset or liability affected.

22. Financial instruments

As part of its operations, the Company carries a number of financial instruments. It is management's opinion that the Company is not exposed to significant interest, currency or credit risks arising from these financial instruments except as otherwise disclosed. The Company's overall risk management program focuses on the unpredictability of the financial market and seeks to minimize potential adverse effects on the Company's financial performance. The Company does not use derivative financial instruments to hedge these risks.

Foreign currency risk

The Company enters into transactions denominated in US dollars for which the related revenues, expenses, accounts receivable and accounts payable and accrued liabilities balances are subject to exchange rate fluctuations.

As at June 30, 2021 the following items are denominated in US dollars:

Foreign currency risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates.

22. Financial instruments (continued)

Sensitivity analysis

At June 30, 2021, if the US Dollar changes by 10% against the Canadian dollar with all other variables held constant, the impact on pre-tax gain or loss for the year ended June 30, 2021 would have been $556,576 (2020 – $174,000).

Credit risk

Credit risk is the risk that one party to a financial instrument will cause a financial loss for the other party by failing to discharge an obligation. The maximum credit risk to which the Company is exposed as at June 30, 2021 represents the carrying amount of cash, accounts receivable and deposits.

Credit concentration

During the three and six months ended June 30, 2021, three customers accounted for 47%, 26%,18% and 31%, 31%, 29% respectively of revenues from operations.

Two customers accounted for 95% (December 31, 2020 – two customers for 69%) of trade accounts receivable with amounts owing to the Company of $8,961,341 (2020 - $1,211,177), representing the Company's major credit risk exposure. Credit concentration is determined based on customers representing 10% or more of total revenues and/or total accounts receivable. The Company believes that there is no unusual exposure associated with the collection of these receivables. The Company manages its credit risk by performing credit assessments of its customers and provides allowances for potentially uncollectible accounts receivable. The Company does not generally require collateral or other security from customers on accounts receivable.

Fair value of financial instruments

Financial instruments are comprised of cash, accounts receivable, investments, deposits, accounts payable and accrued liabilities, term loans, long-term debt and convertible debentures. There are three levels of fair value that reflect the significance of inputs used in determining fair values of financial instruments:

22. Financial instruments (continued)

Investments in BGF shares are valued as at June 30, 2021 at quoted market prices and are classified as Level 1. Investments in BGF shares were valued as at December 31, 2018 based on a valuation technique that estimates a business' value based on a recent round of financing and were classified as Level 3.

Investments in HPQ shares are valued at quoted market prices and are classified as Level 1.

Investments in HPQ warrants are valued using the Black-Scholes pricing model and are classified as Level 3.

The fair values of cash, accounts receivable, accounts payable and accrued liabilities, and term loans approximate their carrying amounts due to their short-term maturities.

The fair value of the long-term debt approximates their carrying amounts due to their recent issuance.

Interest rate risk

Interest rate risk is the risk that the value of a financial instrument might be adversely affected by a change in interest rates. Changes in market interest rates may have an effect on the cash flows associated with some financial assets and liabilities, known as cash flow risk, and on the fair value of other financial assets or liabilities, known as price risk, and on the fair value of investments or liabilities, known as price risks. The Company is exposed to a risk of fair value on the term loans and convertible debentures as those financial instruments bear interest at fixed rates.

Price risk

Price risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market price (other than those arising from foreign currency risk and interest risk), whether those changes are caused by factors specific to the individual financial instrument or its issuers or factors affecting all similar financial instruments traded in the market. The most significant exposure to the price risk for the Company arises from its investments in shares of public companies quoted on the TSXV Exchange. If equity prices had increased or decreased by 25% as at June 30, 2021, with all other variables held constant, the Company’s investments would have increased or decreased respectively, by approximately $6,527,000 (2020 - $11,874,375).

Liquidity risk

Liquidity risk is the risk that the Company will encounter difficulty in meeting obligations associated with financial liabilities that are settled by delivery of cash or another financial asset. The Company's ability to continue as a going concern is dependent on management's ability to raise required funding through future

equity and / or debt issuances and to generate positive cash flows from operations (see note 1 (b)). The Company manages its liquidity risk by forecasting cash flows from operations and anticipating any investing and financing activities. Management and the Board of Directors are actively involved in the review, planning and approval of significant expenditures and commitments.

22. Financial instruments (continued)

The following table summarizes the contractual maturities of financial liabilities as at June 30, 2021:

23. Contingent liabilities

The Company is currently a party to various legal proceedings and a tax authorities’ review. If management believes that a loss arising from these matters is probable and can reasonably be estimated, that amount of the loss is recorded. As additional information becomes available, any potential liability related to these matters is assessed and the estimates are revised, if necessary. Based on currently available information, management believes that the ultimate outcome of these matters, individually and in aggregate, will not have a material adverse effect on the Company’s financial position or overall trends in results of operations.

The Company had received a government grant in prior years of approximately $800,000 to assist with the development of a new system of advanced waste treatment systems technology. The grant is potentially repayable at the rate of 3% of any consideration received as a result of the project, for which funding has been received, to a maximum of the actual grant received. This repayment provision will remain in effect until May 30, 2024. The Company abandoned the project in 2011 and accordingly, no amount is expected to be repaid.

24. Capital management

The Company’s objectives in managing capital are:

The Company’s primary objectives when managing capital is to ensure the entity continues as a going concern as well as to maintain optimal returns to shareholders and benefits for other stakeholders.

The Company currently funds these requirements from cash flows from operations and with financing arrangements with third parties and shareholders. The Company is not subject to any externally imposed capital requirements.

The Company monitors its working capital in order to meet its financial obligations. For the three and six months ending June 30, 2021, the Company’s working capital was $28,373,616 (2020 – $13,797,579).

24. Capital management (continued)

Although there were no significant changes in the Company’s approach during fiscal 2020, the Company was able to retire its term loans and convert its convertible debentures to common shares. In order to maintain or adjust capital structure, the Company may issue new shares, sell portions of its strategic investment and periodically purchase its own shares on the open market.

25. Segment information

The Company operates in one segment, based on financial information that is available and evaluated by the Company’s Board of Directors.

The purchase price will be paid upon AST meeting various contract and business-related milestones.
