Employer Contributions:

Total contributions to be made during fiscal 2013, including the NCRA plan, will depend primarily on market returns on the pension plan assets and minimum funding level requirements. During the three months ended November 30, 2012, CHS and NCRA made no contributions to the pension plans. At this time, we do not anticipate having to make a contribution for our benefit plans in fiscal 2013.
