Leases - Estimating the incremental borrowing rate The Company cannot readily determine the interest rate implicit in the lease, therefore, it uses its incremental borrowing rate (IBR) to measure lease liabilities. The IBR is the rate of interest that the Company would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment. The IBR therefore reflects what the Company ‘would have to pay’, which requires estimation when no observable rates are available (such as for subsidiaries that do not enter into financing transactions) or when they need to be adjusted to reflect the terms and conditions of the lease (for example, when leases are not in the subsidiary’s functional currency). The Company estimates the IBR using observable inputs (such as market interest rates) when available and is required to make certain entity-specific estimates. Identification and fair-value measurement of assets and liabilities acquired in a business combination Business combinations are accounted for using the acquisition method. Such method requires recognizing and measuring the identifiable assets acquired, the liabilities assumed and any non-controlling interest in the acquiree. The Company, as the acquirer, must classify or designate the identifiable assets and liabilities assumed on the basis of its own contractual terms, economic conditions, operating and accounting policies and other relevant conditions as at the acquisition date. Such assessment requires judgments from the Company on the methods used to determine the fair value of the assets acquired and liabilities assumed, including valuation techniques that may require prospective financial information inputs. Impairment of non-financial assets Impairment exists when the carrying value of an asset or cash generating unit (“CGU”) or group of CGUs exceeds its recoverable amount, defined as the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on data available from binding sales transactions, conducted at arm’s length, for similar assets or observable market prices less incremental costs of disposing of the asset. The value in use calculation is based on a discounted cash flow model (“DCF” model). The cash flows are derived from the budget for the next five years and do not include restructuring activities to which the Company has not yet committed or significant future investments that will enhance the performance of the assets of the CGU being tested. The recoverable amount is sensitive to the discount rate used for the DCF model as well as to expected future cash-inflows and the growth rate used for extrapolation purposes. These estimates are most relevant to goodwill and indefinite lived intangible assets recognized by the Company. The key assumptions used to determine the recoverable amount for each CGU, including a sensitivity analysis, are disclosed and further explained in Note 12. Share-based compensation Estimating fair value for share-based payment transactions requires determination of the most appropriate valuation model, which depends on the terms and conditions of the grant.

Significant accounting estimates and assumptions

3 Significant accounting estimates and assumptions

The preparation of the Company’s consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods. Accounting estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Revisions to estimates are recognized prospectively.

Other disclosures relating to the Company’s exposure to risks and uncertainties includes:

· Capital management – Note 15

· Financial instruments risk management objectives and policies – Note 13.4

· Sensitivity analyses disclosures – Note 13.4.1

Estimates and assumptions

The key assumptions about the future and other key sources of estimated uncertainty as of the reporting date that include a significant risk of a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Company based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances that arise and that are beyond the Company’s control. Such changes are reflected in the assumptions where they occur.

Leases - Estimating the incremental borrowing rate

The Company cannot readily determine the interest rate implicit in the lease, therefore, it uses its incremental borrowing rate (IBR) to measure lease liabilities. The IBR is the rate of interest that the Company would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use asset in a similar economic environment. The IBR therefore reflects what the Company ‘would have to pay’, which requires estimation when no observable rates are available (such as for subsidiaries that do not enter into financing transactions) or when they need to be adjusted to reflect the terms and conditions of the lease (for example, when leases are not in the subsidiary’s functional currency).

The Company estimates the IBR using observable inputs (such as market interest rates) when available and is required to make certain entity-specific estimates.

Identification and fair-value measurement of assets and liabilities acquired in a business combination

Business combinations are accounted for using the acquisition method. Such method requires recognizing and measuring the identifiable assets acquired, the liabilities assumed and any non-controlling interest in the acquiree. The Company, as the acquirer, must classify or designate the identifiable assets and liabilities assumed on the basis of its own contractual terms, economic conditions, operating and accounting policies and other relevant conditions as at the acquisition date. Such assessment requires judgments from the Company on the methods used to determine the fair value of the assets acquired and liabilities assumed, including valuation techniques that may require prospective financial information inputs.

Impairment of non-financial assets

Impairment exists when the carrying value of an asset or cash generating unit (“CGU”) or group of CGUs exceeds its recoverable amount, defined as the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on data available from binding sales transactions, conducted at arm’s length, for similar assets or observable market prices less incremental costs of disposing of the asset. The value in use calculation is based on a discounted cash flow model (“DCF” model). The cash flows are derived from the budget for the next five years and do not include restructuring activities to which the Company has not yet committed or significant future investments that will enhance the performance of the assets of the CGU being tested. The recoverable amount is sensitive to the discount rate used for the DCF model as well as to expected future cash-inflows and the growth rate used for extrapolation purposes.

These estimates are most relevant to goodwill and indefinite lived intangible assets recognized by the Company. The key assumptions used to determine the recoverable amount for each CGU, including a sensitivity analysis, are disclosed and further explained in Note 12.

Share-based compensation

Estimating fair value for share-based payment transactions requires determination of the most appropriate valuation model, which depends on the terms and conditions of the grant. This estimate also requires determination of the most appropriate inputs to the valuation model including the expected life of the share option or appreciation right, volatility and dividend yield and making assumptions about them. For the measurement of the fair value of equity-settled transactions, the Company uses the Binomial model. As disclosed on Note 16 (b) the Company had stock plans that were fully exercised on July 31, 2019, for which the Monte Carlo and Black & Scholes pricing model were used for the Afya Brazil and Guardaya plans, respectively. The assumptions and models used for estimating fair value for share-based payment transactions are disclosed in Note 16 (b).
