© 2016 Avaya Inc. All rights reserved. 11 Fiscal Q2 2016 Financial Outlook (As Delivered 02/08/2016)  Given our current visibility, our backlog, and the potential continued headwinds from macroeconomic and currency-related uncertainty, we believe the second fiscal quarter revenue will be in the range of $915million to $955 million dollars.  Compared to Q2 FY ‘15, this is down 3% to 7%. In the past four years, second quarter revenue has declined sequentially by 6% to 10% and has declined by 2% to 11% year-over-year.  We also expect EBITDA will be in the range of 22.5 percent to 24.5 percent of revenue.  We continue to expect total cash requirements for restructuring, pension, interest, cash taxes and capital spending in fiscal 2016 to be $870 million or less with restructuring cash of approximately $100 million and pension contributions in the range of $150 to $160 million.  We expect cash restructuring requirements for the second fiscal quarter to be approximately $30 million dollars, primarily associated with previously announced headcount-related actions, particularly in EMEA. Also, our semi-annual interest on the 10.5 percent notes will be paid in the March quarter.  This is expected to result in total cash requirements for the second quarter of between $235 and $245 million dollars, which is a sequential increase of $55 to $65 million dollars.
