On the Interest Reset Date, which is the day after the 3 month T Bill auction, the Calculation Agent will establish the new rate based on the BEY for the 3 month T Bill auction pulished in H.15 (http://www.publicdebt.treas.gov/of/ofrespr.htm).

In the event that the results of the 91 day Treasury Bill auction ceases to be published or reported, or that no auction is held in a particular week, then the rate in effect as a result of the last such report will remain in effect until such time, as the results of auctions of 91 day Treasury Bills will again be published.
