Certain leases are accounted for as sales-type leases.  For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment.  Other revenues include interest income on sales-type leases and rental income on facility leases.</font></p> <p style="text-align:justify;margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-weight:bold;font-family:Times New Roman;font-size:10pt;font-style:normal;text-transform:none;font-variant: normal;">Non-lease revenues<font style="font-weight:normal;"> - Sales revenue is recognized upon delivery and installation of the equipment to customers.  Certain leases are accounted for as sales-type leases.  For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment.</font></p> <p style="text-align:justify;margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Other revenue is recognized when earned and primarily includes interest income on sales-type leases, rental income on facility leases and certain logistics services.</p> <p style="text-align:justify;margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Sales taxes charged to customers are reported on a net basis and are excluded from revenues and expenses.</p>
