Competition

We compete for investments with a number of BDCs and investment funds (including private equity and hedge funds), as well as traditional financial services companies such as commercial banks and other sources of financing. Many of these entities have greater financial and managerial resources than we do. We believe we are able to be competitive with these entities primarily on the basis of the experience and contacts of our management team, our responsive and efficient investment analysis and decision-making processes, the investment terms we offer, the model that we employ to perform our due diligence with the broader New Mountain Capital team and our model of investing in companies and industries we know well.

We believe that some of our competitors may make investments with interest rates and returns that are comparable to or lower than the rates and returns that we target. Therefore, we do not seek to compete solely on the interest rates and returns that we offer to potential portfolio companies. For additional information concerning the competitive risks we face, see
