Our acquisition process has been very robust this year. We've acquired 4 facilities with trailing revenue over $550 million. Our acquisition of assets in Memorial Hospital in York, Pennsylvania was completed on July 1, 2012. The assets include 110 bed hospital as other, as well as other outpatient ancillary services.
The price for the fixed assets was $45 million or 40% of trailing revenue of $115 million. The hospital's trading margin is below single digits. While we've agreed to replace a placement hospital, it will not start construction for several years, and this is our 17th hospital in Pennsylvania.
The seller has disclosed a letter of intent for 2 hospital system with hospitals located in Wheeling, West Virginia and Martins Ferry, Ohio. This system has a total of 636 licensed beds and trailing revenue of approximately $170 million.
We continue to look for strategic opportunities and have a very strong and active pipeline.

As for the group of investigations that involve medical necessity of inpatient admissions, we continue to cooperate by providing documents and making witnesses available, as well as participating in meetings with the government to discuss the cases. We had hoped to be in the process on the probe audit we described in April. A third-party review of sample medical records had a small number of our hospitals. That review has not begun yet.
