27Employee benefit expenses
Accounting policy
(i)Profit sharing
A provision is recorded to recognize the expenses related to employee profit sharing. This provision is calculated based on the qualitative and quantitative targets established by management and are recorded as “Employee benefits” in the income statement.
(ii)Share-based payments
The subsidiary NEXA PERU operates a cash-settled, share-based compensation plan, under which the company gives certain executives a package of equity instruments (options) as consideration for services received, which is based on the value of equity instruments (“Phantom options”) of the NEXA PERU.
The cost of the cash settled share-based payments plan is initially measured at fair value as at the grant date using the Black-Scholes financial model. This fair value is accrued over the period until the vesting date, with the recognition of the liability. The liability is measured again at fair value at each reporting date, and it is reported up to and including the settlement date, with changes in fair values recognized as expenses of employee benefits in the income statement.
The purpose of such incentive plan is to align a portion of the compensation of the company’s senior executives with the evolution of the NEXA PERU’s market value.
