 Structure and Strategy Misaligned  Portfolio Composition Impediment to Value Creation  Historical All-Equity Investment Strategy  Challenges All Surmountable  Strategy Misaligned with BDC / RIC Structure  CSWC’s strategy was to invest solely in equity and hold almost indefinitely Certain investments have been held for many decadesLarger control assets had a very low cost basis, a large embedded capital gain and a significant tax due upon divestiture  Value creation almost exclusively from equity appreciation rather than investment incomeLack of investment income = insignificant and inconsistent shareholder dividendsBDC/RIC designation restricts investments in control companies and asset concentrationsFinancial and operating performance of large industrial assets shrouded by investment company accounting method used by CSWC  Vast majority of portfolio value in strong companies100% owned industrial assets are now large enough to stand alone outside of BDC portfolio Seller’s market favorable to the divestiture of minority equity positionsManagement relationships would facilitate team augmentation with credit experience  12/31/2013 Portfolio  All equityLarge concentrationsLarge public company holdingsEmbedded gains
