Retirement Benefits. In addition to base salary, annual cash incentives, and long-term equity incentives, our Named Executive Officers are eligible to participate in the same broad-based, tax-qualified retirement and savings plans as other employees with similar dates of hire. They are also eligible to participate in certain non-qualified supplemental executive retirement plans because applicable tax rules do not permit them to receive benefits under our broad-based, tax-qualified plans at the same percentage of salary as other employees. The supplemental executive retirement plans generally provide benefits that, when added to the benefits available under our qualified plans, approach being equivalent, as a percentage of salary, to the benefits provided to other employees. We provide these benefits in lieu of additional current cash or equity compensation to assure that our Named Executive Officers have a source of retirement income that is consistent and available at the time of
retirement without regard to the performance of their personal savings and investment portfolios and because these programs enjoy more favorable corporate and/or personal income tax treatment under the federal tax laws than current compensation. Although we also use the supplemental plans to provide additional pension benefits to executives who are recruited from other employers in mid-career, we do not currently grant additional years of service credits for periods of employment with a prior employer as part of the employment negotiation. Our broad-based and executive-level retirement programs have benefit formulas that are tied to base salary. Cash incentives, restricted stock, option-related compensation and other items of compensation do not increase or reduce benefit levels.
