Net sales are defined as net sales to external clients. None of our clients exceeded ten percent of consolidated net sales for the three months ended March 31, 2020 or 2019. A portion of our operating segments’ selling and administrative expenses arise from shared services and infrastructure that we have historically provided to them in order to realize economies of scale and to use resources efficiently. These expenses, collectively identified as corporate charges, include senior management expenses, internal audit, legal, tax, insurance services, treasury and other corporate infrastructure expenses. Charges are allocated to our operating segments, and the allocations have been determined on a basis that we consider to be a reasonable reflection of the utilization of services provided to or benefits received by the operating segments.
