We finance a large portion of customer purchases of Xerox equipment through our bundled lease arrangements. We believe that financing facilitates customer acquisition of Xerox technology and enhances our value proposition to the customer while providing Xerox a profitable revenue stream and a strong return on equity.
As a result of our customer financing program, we benefit by gaining in-depth knowledge of the products being leased and a deep understanding of the customer base and their use of our technology. This knowledge allows us to effectively manage the credit and residual value risk normally associated with financing. Our financing risk is further mitigated because the majority of our lease contracts are non-cancelable and include cancellation penalties approximately equal to the full value of the lease receivables.
Because our lease contracts permit customers to pay for equipment over time rather than at the date of installation, we maintain a certain level of debt to support our investment in these lease contracts. We fund our customer financing activity through a combination of cash generated from operations, cash on hand, borrowings under bank credit facilities and proceeds from capital market offerings. At December 31, 2008 we had $7.3 billion of finance receivables and $0.6 billion of equipment on operating leases, or Total Finance assets of $7.9 billion. We maintain an assumed 7:1 leverage ratio of debt to equity as compared to our Finance assets and therefore a significant portion of our $8.4 billion of debt is associated with our financing business.
In addition to being an excellent customer retention vehicle, our customer financing program also achieves an attractive gross margin which provides us a reasonable return on our investment in this business. This program is also a strong value proposition for our customers because it provides them a bundled monthly payment for their document management needs and an attractive financing alternative.
