Inversiones Aguas Metropolitanas 41 Annual Report 2017 Risk Factors Financial Management Seasonality Operational The water utility business is characterized by seasonality, risks which could lead to possible variations in results from quarter to quarter. The highest levels of demand and income are recorded during the summer months (December to March in the southern hemisphere), whilst the lowest demand coincides with the winter months (June to September).

Weather conditions The processes of catchment and production of potable water depend mainly on the climatic conditions in the river basins. Precipitations, temperature, sediment carryover, drought, among other factors, determine the quantity, quality and continuity of raw water available. In order to face these phenomena, IAM’s water utility facilities have water reserves and contingency plans which are constantly updated.

New investments IAM’s subsidiaries must comply with the development plans committed to the Superintendence of Sanitation Services (SISS), which involve economic, administrative and technical resources. However, the tariffs charged to customers include these new investments, guaranteeing
