Our homebuilding operations are engaged in the development, design, construction, marketing and sale of single-family attached and detached homes in 17 states. We build and sell homes under our Century Communities and Century Complete brands. Our Century Communities brand is managed by geographic location, and each of our four geographic regions targets a wide range of buyer profiles including: first time, first and second time move up, and lifestyle homebuyers, and provides our homebuyers with the ability to personalize their homes through certain option and upgrade selections. Each of our four geographic regions is considered a separate operating segment. Our Century Complete brand targets first time homebuyers, primarily sells homes through retail studios and the internet, and provides no option or upgrade selections. Our Century Complete brand currently has operations in 11 states and is managed separately from our four geographic regions. Accordingly, it is considered a separate operating segment.

The management of our four geographic regions and Century Complete reports to our chief operating decision makers (which we refer to as “CODMs”), the Co-Chief Executive Officers of our Company. The CODMs review the results of our operations, including total revenue and income before income tax expense to determine profitability and to allocate resources. Accordingly, we have presented our homebuilding operations as the following five reportable segments:

Century Complete (Alabama, Arizona, Florida, Georgia, Indiana, Iowa, Michigan, North Carolina, Ohio, South Carolina, and Texas)

We have also identified our Financial Services operations, which provide mortgage, title, and insurance services to our homebuyers, as a sixth reportable segment. Our Corporate operations are a non-operating segment, as they serve to support our homebuilding, and to a lesser extent our financial services operations, through functions, such as our executive, finance, treasury, human resources, accounting and legal departments. The following table summarizes total revenue and income before income tax expense by segment (in thousands):
