Transformed in 2008 and 2009 During 2008 and 2009, in the midst of an economic downturn and while CapitalSource was transforming from a Finance Company to a Bank, the following changes in lending practices were implemented: Expanded lending efforts: Timeshare Healthcare real estate Technology cash flow Loans to home and commercial security monitoring companies Added new lending lines: Equipment finance Small business lending (SBA) Multifamily Reduced risk by: Discontinuing lending on real estate with insufficient in-place cash flow at closing, including repositioned assets. Limiting construction lending and eliminating land-secured loans Eliminating mezzanine or second lien lending on real estate Curtailing general cash flow lending and focusing on specific cash flow industry niches. Eliminating cash flow lending to media companies, and curtailing cash flow lending to retailers.
