Item 2. Properties.

Our corporate headquarters are located in Denver, Colorado, consisting of one owned 240,000 square foot building and one leased 345,900 square foot location. Our headquarters are occupied by teammates engaged in management, finance, marketing, strategy, legal, compliance and other administrative functions. We lease five business offices located in California, Pennsylvania, Tennessee and Washington, and own one business office in Washington in the U.S. In addition, our international headquarters is located in the United Kingdom and consists of one leased business office. Our laboratory is based in Florida where we operate our lab services out of one leased building. We also lease other administrative offices in the U.S. and worldwide.

For our U.S. dialysis business we own the land and buildings for five outpatient dialysis centers. We also own 16 properties for development, including operating outpatient dialysis centers and properties we hold for sale. Our remaining outpatient dialysis centers are located on premises that we lease.

The majority of our leases for our U.S. dialysis business cover periods from five years to 15 years and typically contain renewal options of five years to ten years at the fair rental value at the time of renewal. Our leases are generally subject to periodic consumer price index increases, or contain fixed escalation clauses. Our outpatient dialysis centers range in size from approximately 1,000 to 33,000 square feet, with an average size of approximately 7,800 square feet. Our international leases generally range from one to ten years.

Some of our outpatient dialysis centers are operating at or near capacity. However, we believe that we have adequate capacity within most of our existing dialysis centers to accommodate additional patient volume through increased hours and/or

days of operation, or, if additional space is available within an existing facility, by adding dialysis stations. We can usually relocate existing centers to larger facilities or open new centers if existing centers reach capacity. With respect to relocating centers or building new centers, we believe that we can generally lease space at economically reasonable rates in the areas planned for each of these centers, although there can be no assurances in this regard. Expansion of existing centers or relocation of our dialysis centers is subject to review for compliance with conditions relating to participation in the Medicare ESRD program, among other things. In states that require a certificate of need or center license, additional approvals would generally be necessary for expansion or relocation.
