Text wrapping a footer in a specific LaTeX template

Question

I'm new to LaTeX (<48hrs experience) and am currently writing up a whitepaper using a the "Technical Report" template available through TeXnicCenter (code available at http://pastebin.com/mku5maC6.)

I would like to add a two sentence disclosure footer, but my text spills off the page and I receive an Overfull error. Neither \sloppy nor \usepackage{microtype} resolved the issue.

The code in question is:

% ********* Header and Footer **********
% This is something to play with forever. I use here the advanced settings of the KOMA script

\usepackage{scrpage2} %header and footer using the options for the KOMA script
\renewcommand{\headfont}{\footnotesize\sffamily} % font for the header
\renewcommand{\pnumfont}{\footnotesize\sffamily} % font for the pagenumbers

%the following lines define the pagestyle for the main document
\defpagestyle{cb}{%
(\textwidth,0pt)% sets the border line above the header
{\pagemark\hfill\headmark\hfill}% doublesided, left page
{\hfill\headmark\hfill\pagemark}% doublesided, right page
{\hfill\headmark\hfill\pagemark}%  onesided
(\textwidth,1pt)}% sets the border line below the header
%
{(\textwidth,1pt)% sets the border line above the footer
{{\it Federation Confidential}\hfill Chief O'Brian}% doublesided, left page
{Chief O'Brian\hfill{\it Federation Confidential}}% doublesided, right page
{Chief O'Brian\hfill{\it Federation Confidential}} % one sided printing
(\textwidth,0pt)% sets the border line below the footer
}

My attempt:

% ********* Header and Footer **********
% This is something to play with forever. I use here the advanced settings of the KOMA     script

\usepackage{scrpage2} %header and footer using the options for the KOMA script
\renewcommand{\headfont}{\footnotesize\sffamily} % font for the header
\renewcommand{\pnumfont}{\footnotesize\sffamily} % font for the pagenumbers

%%the following lines define the pagestyle for the main document
\defpagestyle{cb}{%
(\textwidth,0pt)% sets the border line above the header
{\pagemark\hfill\headmark\ Company X, LLC}% doublesided, left page
{Company X, LLC\headmark\hfill\pagemark}% doublesided, right page
{Company X, LLC\headmark\hfill\pagemark}%  onesided
(\textwidth,1pt)}% sets the border line below the header
%
{(\textwidth,1pt)% sets the border line above the footer
{\it This document contains unpublished confidential and proprietary information of      Company X. No disclosure or use of
any portion of these materials may be made without the express written consent of   Company X.}% doublesided, left page
{\it This document contains unpublished confidential and proprietary information of   Company X. No disclosure or use of
any portion of these materials may be made without the express written consent of  Company X.}% doublesided, right page
{\it This document contains unpublished confidential and proprietary information of Company X. No disclosure or use of
any portion of these materials may be made without the express written consent of Company     X.} % one sided printing
(\textwidth,0pt)% sets the border line below the footer
}

Any help or guidance would be much appreciated.

Answer 1

The footer's reference point is placed in a fixed position, so you need to use \parbox[t]{...}{...}; here's an example:

\documentclass[a4paper]{scrreprt}

\usepackage{scrpage2} %header and footer using the options for the KOMA script
\renewcommand{\headfont}{\footnotesize\sffamily} % font for the header
\renewcommand{\pnumfont}{\footnotesize\sffamily} % font for the pagenumbers

\newcommand{\confidentialtext}{\parbox[t]{\textwidth}{This document contains unpublished
  confidential and proprietary information of Company X. No disclosure or use of any
  portion of these materials may be made without the express written consent of Company X.}}

%%the following lines define the pagestyle for the main document
\defpagestyle{cb}{%
  (\textwidth,0pt)% sets the border line above the header
  {\pagemark\hfill\headmark\ Company X, LLC}% doublesided, left page
  {Company X, LLC\headmark\hfill\pagemark}% doublesided, right page
  {Company X, LLC\headmark\hfill\pagemark}%  onesided
  (\textwidth,1pt)}% sets the border line below the header
%
  {(\textwidth,1pt)% sets the border line above the footer
  {\slshape\confidentialtext}% doublesided, left 
  {\slshape\confidentialtext}% doublesided, right page
  {\slshape\confidentialtext}% one sided printing
  (\textwidth,0pt)% sets the border line below the footer
}

\usepackage{kantlipsum} % for the mock text

\begin{document}
\pagestyle{cb}
\kant
\end{document}

Notice that I've put the footer's text in a more convenient form: with a macro you don't need to edit the same text over and over. Since it is in sans serif type, \slshape is better suited.
