Retirement-Related Benefits

The Company offers a 401(k) plan for associates in the U.S. under which eligible associates can begin contributing to the plan immediately upon hire. The Company also offers a 401(k) type plan for associates in Puerto Rico under which associates can begin to contribute generally after one year of employment. Under these plans, after one year of employment, the Company matches 100% of participant contributions up to 6% of annual eligible earnings. The matching contributions immediately vest at 100% for each associate. Participants can contribute up to 50% of their pretax earnings, but not more than the statutory limits.

Associates in international countries who are not U.S. citizens are covered by various defined contribution post-employment benefit arrangements. These plans are administered based upon the legislative and tax requirements in the countries in which they are established.
