Our revised guidance is as follows:
|Payroll service revenue||2||%||
|Total service revenue||5||%||—||6||%|
|Interest on funds held for clients||(8||)%||—||(6||)%|
|Investment income, net||—||—||
Operating income, net of certain items, as a percent of total service revenue is expected to be approximately 37% for fiscal 2013. The effective income tax rate for fiscal 2013 is expected to approximate the tax rate for the first six months.
