Provisions for other liabilities

The Group is subject to several laws, regulations and business practices of the countries where it operates. In the ordinary course of business, the Group is subject to certain contingent liabilities with respect to existing or potential claims, lawsuits and other proceedings, including those involving tax, labor and social security, administrative and civil and other matters. The Group accrues liabilities when it is probable that future costs will be incurred and it can reasonably estimate them. The Group bases its accruals on up-to-date developments, estimates of the outcomes of the matters and legal counsel experience in contesting, litigating and settling matters. As the scope of the liabilities becomes better defined or more information is available, the Group may be required to change its estimates of future costs, which could have a material effect on its results of operations and financial condition or liquidity.
