-performance factor changes |     | 4Traditional pension plans are extremely sensitive to interest rate changes, which are macroeconomic factors out of the Company’s control                                                                                                                
 4Unlike the short-term and long-term incentive programs which are purely performance based, pension values are driven mostly by non-performance factors                                                                                                  |
| Compensation Committee committed to the ongoing sustainability of the pension plan  |     | 4Over the years, the Committee has taken actions to promote the sustainability of pension benefits for the future, shift to a more shared responsibility between employer and employee and meet evolving workforce needs to attract and retain employees 
 4Eligibility was closed to additional participants in the SERP nonqualified pension plan program beginning in 2016                                                                                                                                       
 4The pension plan formula changed in 2018 for new participants from a final average earnings formula to a cash balance formula                                                                                                                           
 4The Committee will continue to assess the pension program so that it attracts, engages, includes and retains the workforce necessary for today and tomorrow                                                                                             |

The values reported in this column are calculated pursuant to SEC requirements and are based on assumptions used in preparing the Company’s audited financial statements for the applicable fiscal years, as described further on page 71 .
