Vince, a single individual, is one of the founders and original shareholders of Security Consulting, Inc., a corporate security consulting firm. The company was initially capitalized with $200,000, and Vince was a 50 percent owner with an investment of $100,000. The company was structured as a C corporation. Filing requirements and permissible tax elections that could benefits the owners were made at the time the company was created. After several years of successful operations, Security Consulting lost market share to large national firms, and eventually closed down operations.
