The traditional final average pay plan is noncontributory, covers select employees, and provides retirement benefits based on the employees’ years of benefit service, average final compensation and age at retirement. The cash balance plan is also noncontributory, covers substantially all employees, and provides retirement benefits based on eligible compensation and interest credits. While we are obligated to fund the retirement plan by contributing the minimum amount required by the Employee Retirement Income Security Act of 1974, as amended, it is our practice to contribute the maximum allowable amount as defined by section 404 of the Internal Revenue Code. We contributed $6.0 million to the defined benefit retirement plan in July 2010. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     We have also established two supplemental nonqualified, noncontributory, retirement benefit plans for selected management employees.
