ABOUT US OUR BUSINESS PORTFOLIO INVESTOR RELATIONS CONTACT US Value-focused investing. Our investment strategy is based on the premise that lower middle market companies require flexible and creative financing solutions from value-added partners. We fully understand that our success depends on that of our portfolio companies. To that end, we invest the time, human resources, and capital necessary to create value for all our constituents, including our portfolio companies, management teams, co-investors, and shareholders. We intend to invest primarily in mezzanine debt, senior secured debt, and equity securities of lower middle market companies, which we define as companies with revenues of $10 to $150 million. When the right opportunity presents itself, we may occasionally make investments in larger or smaller companies. Our approach is to invest in lower middle market companies with proven business models, leading market positions, high free cash flow, and strong management teams. In addition, we focus on opportunities in industries where we have prior investment experience. We believe that by continuing to adhere to this philosophy, we can generate attractive risk-adjusted returns and minimize capital losses. Our investment strategy also includes taking a proactive stance towards risk management. This includes conducting intensive due diligence prior to investing, utilizing our flexible mandate to structure our investments so as to withstand both positive and negative events, and ongoing and active portfolio management, including board observation rights in conjunction with almost all of our investments. We believe this strategy enhances our ability to be a value-added partner for our portfolio companies.
