The information in this Current Report on Form 8-K and the attached supplemental information contain forward-looking statements. The forward-looking statements are based on certain assumptions and analyses made by the Partnership in light of its experience and its perception of historical trends, current conditions, expected future developments, and other factors it believes are appropriate in the circumstances. Such statements are subject to a number of risks and uncertainties, many of which are beyond the control of the Partnership. Investors are cautioned that any such statements are not guarantees of future performances or results and that actual results or developments may differ materially from those projected in the forward-looking statements. Some of the factors that could affect actual results are described in the Partnership Annual Report on Form 10-K for the year ended December 31, 2015, as well as other risks identified from time to time in its Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC. The Partnership undertakes no obligation to update or revise any forward-looking statement to reflect new information or events. Forward-looking statements in this Current Report on Form 8-K relate to, among other things, the integration of CVR Nitrogen, LP (f/k/a East Dubuque Nitrogen Partners, L.P. and f/k/a Rentech Nitrogen Partners, L.P.) and the Private Offering (as defined below) and the use of proceeds therefrom.
