F1	This acquisition resulted from the reporting person's election in a prior year (pursuant to the Company's Director Deferral Plan) to defer the reporting person's annual cash retainer, which the Company pays on a quarterly basis, into deferred share units that will be distributed in the form of the Company's common stock.
