The table below is a summary of certain cash flows received from and paid to the trusts during the year. In 2004, we recognized a pre-tax loss of $26 million on the revolving sale of accounts receivable for the combined securitizations, compared to a pre-tax loss of $33 million in 2003. The table below shows balances for the combined securitizations at December 31, 2004 and the assump- tions that were used in the model on the date of  transfer and at December 31, 2004. A 10% or 20% adverse change in each of these assumptions would have no significant effect on the current fair value of the retained interest. 2004 2003 Collections reinvested in revolving sales 14,331 13,612 Increase (decrease) in sale proceeds  95 (5) Note  12 : Other Current Assets  NOTE 2004 2003 Future income taxes  8 489  197  Inventory 357  295  Prepaid expenses 256  195  Other  109  52  1,211  739 RANGE 2004 2003 Securitized interest in  accounts receivable 1,125 1,030 Retained interest 176 157 Servicing liability 1.3 1.4 Average accounts  receivable managed 1,323 1,265 Assumptions: Cost of funds 2.25%–3.05% 2.55% 3.22% Average  delinquency ratio 7.61%–8.24% 8.24% 7.58% Average net  credit loss ratio 0.91%–1.07% 1.03% 0.95% Weighted average  life (days) 32–35 32 35 Servicing fee liability 2.00% 2.00% 2.00% 2004 2003 ACCUMULATED NET BOOK ACCUMULATED NET BOOK COST AMORTIZATION VALUE COST AMORTIZATION VALUE Telecommunications assets Inside plant 20,066 13,836 6,230 20,234 13,588 6,646 Outside plant 12,627 8,008 4,619 12,221 7,658 4,563 Station equipment 2,788 1,625 1,163 2,759 1,526 1,233 Machinery and equipment 5,529 3,039 2,490 5,179 2,790 2,389 Buildings 2,682 1,384 1,298 2,551 1,308 1,243 Plant under construction 1,605 – 1,605 1,372 – 1,372 Satellites 1,769 758 1,011 1,376 704 672 Land 95 – 95 96 – 96 Other 278 97 181 506 225 281 Total property, plant and equipment 47,439 28,747 18,692 46,294 27,799 18,495 Finite-life intangible assets  Software 3,242 1,295 1,947 2,934 1,063 1,871 Customer relationships 603 42 561 603 21 582 Other 279 81 198 224 58 166 Total capital assets 51,563 30,165 21,398 50,055 28,941 21,114 Note  13 : Capital Assets  Bell Canada Enterprises  2004 Annual Report 103
