On August 28 we issued $1.25 billion aggregate principal amount of 5 ¾ percent senior notes due 2022 (New Senior Notes). All of the proceeds from the issuance of the New Senior Notes along with related fees and interest through November 30 were deposited into escrow pending the consummation of the HCP acquisition.

- Center Activity: As of September 30 we operated or provided administrative services at 1,912 outpatient dialysis centers located in the United States serving approximately 150,000 patients and 24 outpatient dialysis centers serving approximately 1,200 patients that are located in five countries outside of the United States. During the third quarter of 2012, we acquired 10 centers and opened a total of 21 centers located in the United States.

We are updating our operating income guidance for 2012 for our dialysis services and related ancillary businesses to now be in the range of $1,315 million to $1,330 million. Our previous operating income guidance for our dialysis services and related ancillary businesses was in the range of $1,275 million to $1,325 million. Following the expected close of the HCP acquisition in early November 2012, we expect the incremental operating income contribution from HCP to be in the range of $25 million to $30 million per month for the remainder of the year. Our operating income guidance for our dialysis services and related ancillary businesses for 2012 excludes the legal proceeding contingency accrual and related expenses of $78 million and transaction expenses related to the HCP acquisition.
Our consolidated operating income guidance for 2013 is expected to be in the range of $1,750 million to $1,900 million including the operating results of HCP. Our operating income guidance for 2013 for our dialysis services and related ancillary businesses is expected to be in the range of $1,350 million to $1,450 million and our operating income guidance for 2013 for HCP is expected to be in the range of $400 million to $450 million. We also expect our consolidated operating cash flows for 2013 to be in the range of $1,350 million to $1,500 million.
