During the year ended December 31, 2011, we changed the name of our seniors housing and care segment to seniors housing triple-net. Additionally, we added a new seniors housing operating segment. There was no activity related to this segment prior to September 1, 2010. We invest in seniors housing and health care real estate. We evaluate our business and make resource allocations on our three business segments: seniors housing triple-net, seniors housing operating and medical facilities. Our seniors housing triple-net properties include skilled nursing/post-acute facilities, assisted living facilities, independent living/continuing care retirement communities and combinations thereof. Under the seniors housing triple-net segment, we invest in seniors housing and health care real estate through acquisition and financing of primarily single tenant properties. Properties acquired are primarily leased under triple-net leases and we are not involved in the management of the property. Our seniors housing operating properties include assisted living facilities and independent living/continuing care retirement communities that are owned and/or operated through RIDEA partnership structures. Our primary medical facility properties include medical office buildings, hospitals and life science buildings. Our medical office buildings are typically leased to multiple tenants and generally require a certain level of property management. Our hospital investments are structured similar to our seniors housing triple-net investments. Our life science investments represent investments in an unconsolidated entity (see Note 7 for additional information). The accounting policies of the segments are the same as those described in the summary of significant accounting policies (in Note 2 to our audited consolidated financial statements). There are no intersegment sales or transfers. We evaluate performance based upon net operating income of the combined properties in each segment. Non-segment revenue consists mainly of interest income on non-real estate investments and other income. Non-segment assets consist of corporate assets including cash, deferred loan expenses and corporate offices and equipment among others. Non-property specific revenues and expenses are not allocated to individual segments in determining net operating income.

Summary information for the reportable segments during the years ended December 31, 2011, 2010 and 2009 is as follows (in thousands and includes amounts from discontinued operations):
