• The current replacement cycle suggests gaming devices should last 16+ years versus an average of 9 years from 2001 – 2006. • If the replacement cycle in 2007-08 kept pace with 2001-06 levels, an additional 76,600 machines would have been replaced (8% of the installed base). • The N.A. replacement cycle should rebound due to the following: • Aging floors and technology obsolescence • Need for customers to reinvest in existing assets to drive profits • Pressure from new competition with fresh floors • Investments in slot floors have a proven and immediate ROI Implied Average Machine Life 18 16 16
