Note 17  Business Segment Reporting Our business segments reflect the internal reporting that we use to evaluate operating performance of services and to assess the allocation of our resources. A brief description of our current business segments is as follows: Servicing. This segment is primarily comprised of our core residential servicing business. We provide residential and commercial mortgage loan servicing, special servicing and asset management services. We earn fees for providing these services to owners of the mortgage loans and foreclosed real estate. In most cases, we provide these services either because we purchased the MSRs from the owner of the mortgage, retained the MSRs on the sale of residential mortgage loans or because we entered into a subservicing or special servicing agreement with the entity that owns the MSR. Our residential servicing portfolio includes conventional, government-insured and non-Agency loans. Non-Agency loans include subprime loans, which represent residential loans that generally did not qualify under GSE guidelines or have subsequently become delinquent. Lending. The Lending segment originates conventional and government-insured residential forward and reverse mortgage loans through correspondent lending arrangements, broker relationships (wholesale) and directly with mortgage customers (retail). The loans are typically sold shortly after origination into a liquid market on a servicing retained (securitization) or servicing released (sale to a third party) basis.
