During the three and six months ended June 30, 2013, we contributed approximately $6 million and $8 million, respectively, to our pension and postretirement benefit plans. For the remainder of 2013, we expect to contribute approximately $5 million to our pension and postretirement benefit plans. A portion of this funding will be reimbursed for costs related to employees of managed hotels.
