Introduction

On September 8, 2011, we filed a Current Report on Form 8-K (the “Current Report”) describing, in Item 8.01 thereof, a change of our ticker symbol from “XRU” to “FXRU,” and, in Item 9.01 thereof, a Press Release dated September 8, 2011 (the “Original Press Release”) announcing the ticker symbol change. The Original Press Release incorrectly reported the new ticker symbol as “XFRU” instead of “FXRU.” Later that same day, we issued a second press release (the “Second Press Release”) correctly reporting our new ticker symbol as “FXRU.” This Amendment No. 1 to the Current Report is being filed to update our periodic reporting file by adding the Second Press Release to that file.

Item 9.01. Financial Statements and Exhibits

The following is filed as an Exhibit to this Report.
