Interest on funds held for clients and investment income for fiscal 2013 are expected to continue to be impacted by changes in the interest rate environment. Our rate of return will be impacted by an anticipated change in mix in our short-term portfolio to a greater percentage of tax-exempt securities. Tax exempt securities typically earn a lower rate of return, but are expected to lower income tax expense on interest earned. Investment income is expected to benefit from ongoing investment of cash generated from operations.Note 1: In addition to reporting operating income, a United States (“U.S.”) generally accepted accounting principle (“GAAP”) measure, we present operating income, net of certain items, which is a non-GAAP measure. We believe operating income, net of certain items, is an appropriate additional measure, as it is an indicator of our core business operations performance period over period. It is also the basis of the measure used internally for establishing the following year’s targets and measuring management’s performance in connection with certain performance-based compensation payments and awards. Operating income, net of certain items, excludes interest on funds held for clients. Interest on funds held for clients is an adjustment to operating income due to the volatility of interest rates, which are not within the control of management. Operating income, net of certain items, is not calculated through the application of GAAP and is not the required form of disclosure by the Securities and Exchange Commission (“SEC”). As such, it should not be considered as a substitute for the GAAP measure of operating income and, therefore, should not be used in isolation, but in conjunction with, the GAAP measure. The use of any non-GAAP measure may produce results that vary from the GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies.
