The health care real estate investment trust HCP Inc. of Long Beach on Thursday said that it expects about $2.37 billion in net proceeds from an offering of senior unsecured notes.

The proceeds will finance part of the cash portion of its recent $6.1 billion cash-and-stock acquisition of 300 rehabilitation and nursing facilities operated by Toledo, Ohio-based ManorCare. HCP will lease the real estate back to ManorCare to operate.

The offering is expected to close on Monday. The real estate acquisition is expected to close this quarter.

BofA Merrill Lynch, UBS Investment Bank, Wells Fargo Securities, Citi and J.P. Morgan are joint book-running managers for the offering. The total of $2.4 billion in notes have yields ranging from 2.73 percent to 6.83 percent and maturities from 2014 to 2041.

HCP shares were up 34 cents, or less than a percent, to $36.29 in midday trading on the New York Stock Exchange.
