The gross finance lease receivables are reduced as customer payments are received. Approximately $0.1 million and $9.1 million of unguaranteed residual value at June 30, 2013 and December 31, 2012, respectively, were included in gross finance lease receivables. There were no executory costs included in gross finance lease receivables as of June 30, 2013 and December 31, 2012.2The difference between the gross finance lease receivable and the cost of the equipment or carrying amount at the lease inception is recorded as unearned income. Unearned income together with initial direct costs, are amortized to income over the lease term so as to produce a constant periodic rate of return. There were no unamortized initial direct costs as of June 30, 2013 and December 31, 2012.falseNet Investment in Direct Finance Leases (Details) (USD $)NoRoundingUnKnownUnKnownUnKnowntruefalsefalseSheethttp://capps.com/role/NetInvestmentInDirectFinanceLeasesDetails231
