Allowance for Expected Credit Losses

We estimate our expected credit losses primarily by using an aging methodology and establish customer-specific reserves for higher risk trade customers. Our expected credit losses are evaluated and controlled within each geographic region considering the unique credit risk specific to the country, marketplace and economic environment. We take into account past events, current conditions and reasonable and supportable forecasts in developing the reserve.

The following table summarizes our allowance for expected credit losses by operating segment for the nine months ended September 30, 2021:
