Segment Reporting [Abstract]

Segment Reporting, Policy [Policy Text Block]

We have two reportable business segments: Single-Family and Multifamily. The Single-Family business operates in the secondary mortgage market relating to loans secured by properties containing four or fewer residential dwelling units. The Multifamily business operates in the secondary mortgage market relating primarily to loans secured by properties containing five or more residential units. We describe the management reporting and allocation process used to generate our segment results in “Note 10, Segment Reporting.”

We have two reportable business segments: Single-Family and Multifamily. Our CEO is the chief operating decision maker and allocates resources and assesses performance based on these two business segments. Results of our two business segments are intended to reflect each segment as if it were a stand-alone business. The sum of the results for our two business segments equals our consolidated results of operations.
