Some of the companies with the best 401(k) plans include ConocoPhillips, Phillip Morris International, Amgen and Boston Scientific, as of 2014. The companies were ranked in a Bloomberg Business study that relied on employee data from 2012.
Houston-based oil and natural gas company ConocoPhillips ranked first in the study, largely due to its generous matching formula, which contributes a hefty portion of annual employee salaries even for those employees who save only a small portion of their pay. Tobacco giant Phillip Morris ranked second in the survey, due to its 5 percent match contribution coupled with an extra 15 percent compensation. All of the highest-ranked companies were those that chose to offer extra retirement bonuses to employees, even those who put aside very little for their 401(k).
