Operational & Enterprise Convergence 14

Fiscal 2013 Outlook The recent acquisitions of Air Serv, HHA, and Calvert-Jones are expected to be slightly accretive (excluding transaction & integration costs). Collectively, LTM revenue for the three acquisitions was approximately $350 million Labor work days are 261 days, which is one work day fewer than fiscal 2012. The second quarter of fiscal 2013 has the one fewer work day The Company estimates one work day of labor expense for the Janitorial segment is in the range of $3.5 million to $4.5 million on a pre-tax basis Anticipating $1.5 million to $2.5 million increase in State Unemployment Insurance on a pre-tax basis. This increase in operating expense is expected to mostly impact the first half of the fiscal year Annual depreciation and amortization expense because of recent acquisitions, is expected to increase from fiscal 2012 in the range of $17 million to $19 million Interest expense anticipated to be in the range of $14 million to $16 million Capital expenditures are expected to be in the range of $39 million to $43 million Cash taxes are expected to be in the range of $23 million to $27 million; and Effective tax rate in the range of 38 percent to 40 percent. This assumes that the Federal Government extends the Workers Opportunity Tax Credit (WOTC) retroactively 15
