Employee Benefits

All employees except the Associate Divers, the Associate Tugmasters, and union employees in the Pacific Northwest, are eligible to participate in the Company’s 401(k) Retirement Plan after completing six months of service. Each participant may contribute between 1% and 80% of eligible compensation on a pretax basis, up to the annual IRS limit. The Company matches 100% on the first 2% of eligible compensation contributed to the Plan and 50% on the next 2% of eligible compensation contributed to the Plan. Participants’ contributions are fully vested at all times. Employer matching contributions vest over a four-year period. At its discretion, the Company may make additional matching and profit-sharing contributions. During the years ended December 31, 2014, the Company contributed $1.2 million to the plan, and in 2013 and 2012, the Company contributed $1.0 million to the plan in each respective year.

The Company contributes to several multiemployer defined pension plans under the terms of collective-bargaining agreements that cover its union-represented employees. Risks of participating in these multiemployer plans are different from single-employer plans in the following aspects:


•	Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.


•	If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.


•	If the Company chooses to stop participating in its multiemployer plans, it may be required to pay a withdrawal liability based on the underfunded status of the plan.

The following table presents the Company's participation in these plans:

1. The most recent PPA zone status available in 2014 and 2013 is for the plan's year end during 2013 and 2012, respectively. Zone status is based on information received from the plan and is indicative of the plans funding status. Among other factors, plans in the red zone are generally less than 65 percent funded, plans in the orange zone are less than 80 percent funded and have an Accumulated Funding Deficiency in the current year or projected into the next six years, plans in the yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded.

2. The FIP/RP Status P/I column indicates plans for which a financial improvement plan ("FIP") or a rehabilitation plan ("RP") is either pending ("P"), or implemented ("I").

There are currently no plans to withdraw from any of the multiemployer plans in which the Company participates.
