Segment Information We currently operate in 13 states that are grouped into three homebuilding segments based on geography. Revenues from our homebuilding segments are derived from the sale of homes that we construct and from land and lot sales. Our reportable segments have been determined on a basis that is used internally by management for evaluating segment performance and resource allocations. We have considered the applicable aggregation criteria and have combined our homebuilding operations into three reportable segments as follows: West : Arizona, California, Nevada, and Texas East : Delaware, Indiana, Maryland, New Jersey (a) , Tennessee, and Virginia Southeast : Florida, Georgia, North Carolina, and South Carolina (a) During our fiscal 2015, we made the decision that we would not continue to reinvest in new homebuilding assets in our New Jersey division; therefore, it is no longer considered an active operation. However, it is included in this listing because the segment information below continues to include New Jersey. Managements evaluation of segment performance is based on segment operating income (loss). Operating income (loss) for our homebuilding segments is defined as homebuilding and land sales and other revenue less home construction, land development, and land sales expense, commission expense, depreciation and amortization, and certain G&amp;A expenses that are incurred by or allocated to our homebuilding segments. The accounting policies of our segments are those described in Note 2 to the consolidated financial statements within our 2019 Annual Report.
