As of December 31, 2017, our continuing operations occupied 3,651,434 square feet in over 210 locations. We own 911,085 square feet of this space, and lease the balance.

Facilities outside of the United States account for approximately 2,426,445 square feet of our owned and leased property, or approximately 66% of our total occupied space.

Our real property leases are both short-term and long-term. We believe that our properties are well-maintained and are adequate for our present requirements.
