(d)	Functional and presentation currency

These consolidated financial statements are presented in Canadian dollars, which is the functional currency of the Company and all of its subsidiaries, with the exception of Cronos Israel which has a functional currency of the Israeli Shekel ("ILS").

(e)	Estimates and critical judgments by management

The preparation of these consolidated financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the 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. These estimates are reviewed periodically and adjustments are made as appropriate in the year they become known. Items for which actual results may differ materially from these estimates are described in the following section.

(i)	Business combinations

	In determining the appropriate basis of accounting for an acquisition, judgment is used to determine if an acquisition is a business combination or an asset acquisition.

(ii)	Control, joint control, or level of influence

	In determining the appropriate basis of accounting for the Company’s interests in investees, judgment is applied regarding the degree to which the Company has the ability to exert influence directly or indirectly over the investees’ financial and operating activities.

(iii)	Warrants and stock options

	Warrants and stock options are initially valued at fair value, based on the application of the Black-Scholes option pricing model. This pricing model requires management to make various assumptions and estimates which are susceptible to uncertainty, including the volatility of the share price, expected dividend yield, expected term of the warrant or stock option and expected risk-free interest rate.

(iv)	Useful lives and impairment of long-lived assets

	Long-lived assets are defined as property, plant and equipment and intangible assets with finite lives. Depreciation and amortization are dependent upon estimates of useful lives and impairment is dependent upon estimates of recoverable amounts. These are determined through the exercise of judgment, and are dependent upon estimates that take into account factors such as economic and market conditions, frequency of use, anticipated changes in laws, and technological improvements.

(v)	Impairment of cash-generating units and goodwill

	The impairment test for cash generating units ("CGUs") to which goodwill is allocated is based on the value in use of the CGU, determined in accordance with the expected cash flow approach. The calculation is based on assumptions used to estimate future cash flows, the cash flow growth rate and the discount rate.

(e)	Estimates and critical judgments by management (continued)


(vi)	Income taxes

	Income taxes and tax exposures recognized in the consolidated financial statements reflect management's best estimate based on facts known at the reporting date. When the Company anticipates a future income tax payment based on its estimates, it recognizes a liability. The difference between the expected amount and the final tax outcome has an impact on current and deferred taxes when the Company becomes aware of this difference.

	In addition, when the Company incurs losses for income tax purposes, it assesses the probability of taxable income being available in the future based on its budgeted forecasts. These forecasts are adjusted to take into account certain non-taxable income and expenses and specific rules on the use of unused credits and tax losses. When the forecasts indicate that sufficient future taxable income will be available to deduct the temporary differences, a deferred tax asset is recognized for all deductible temporary differences.

(vii)	Biological assets and inventory

	Biological assets, consisting of cannabis plants, are measured at fair value less costs to sell. At the point of harvest, the biological assets are transferred to inventory at fair value less costs to sell. As a result, critical estimates related to the valuation of biological assets are also applicable to inventory. Determining the fair value less costs to sell requires the Company to make assumptions about the expected harvest yield from the cannabis plants, the value associated with each stage of the plants' growth cycle, estimated selling price, processing costs to convert harvested cannabis into finished goods, selling costs, the equivalency factor to convert dry cannabis into cannabis oil and the multiples of crude extract and isolate mass in diluted cannabis oil. The Company's estimates are, by their nature, subject to change. Refer to Note 7.

	Inventory is valued at the lower of cost and net realizable value. Determining the net realizable value requires the Company to make assumptions about the estimated selling price in the ordinary course of business, the estimated costs of completion and the estimated variable costs to sell.

(viii)	Expected credit losses on financial assets

	Determining an allowance for expected credit losses ("ECLs") for all debt financial assets not held at fair value through profit or loss requires management to make assumptions about the historical patterns for the probability of default, the timing of collection and the amount of incurred credit losses, which are adjusted based on management’s judgment about whether economic conditions and credit terms are such that actual losses may be higher or lower than what the historical patterns suggest.

(ix)	Variable consideration in revenue from contracts with customers

	Determining the amount of variable consideration to recognize, and whether the amount of variable consideration should be constrained, is dependent on management's estimate of the most likely amount to which the Company will be entitled and the probability of a significant reversal in that amount. These determinations require management to make estimates based on historical amounts received, current economic conditions, and current industry conditions, in Canada and abroad, adjusted for forward looking information.

(x)	Returns from customers

	Revenue is measured net of returns. As a result, the Company is required to estimate the amount of returns based on the historical data by customer and product type, adjusted for forward-looking information.
