Financial Guarantees And Warranties	18. Financial Guarantees and Warranties Financial Guarantees We have agreements with certain of our Canadian customers' financial institutions under which we have guaranteed the repurchase of our customers' inventory or our customers' debt in the event these customers are unable to meet their obligations to those financial institutions.

The inventory repurchase agreements mostly range from one to two years.

The majority of our customers' debt guarantees are secured by certain assets of the customer.
