|1 | The standby letters of credit maturing in 2015 were issued with a one-year term and will be automatically renewed on a year-by-year basis until the underlying
obligations are resolved. These obligations are primarily the decommissioning and reclamation of Cameco Corporations mining and conversion facilities. As such, the letters of credit are expected to remain outstanding well into the future.
