| (1) |  | The Plan is not subject to the PPA funding requirements under IRS Section 432 as the Plan was not in effect on July 16, 2006.
| (2) |  | In 2012, the Company agreed to contribute at least 11.7 percent of total wages paid to employees in covered Marine Engineer Benefits Association (“MEBA”) employment to the MEBA Pension Trust by a reallocation of the total labor cost under the collective bargaining agreement. The pension contribution rate was determined by the plan’s actuary to be necessary to maintain full funding of the pension plan and is fully offset by a reallocation of wages and other benefits.
| (3) |  | Matson's contributions to these plans commenced after the Horizon Acquisition on May 29, 2015.
| (4) |  | The Company does not make contributions directly to the Seafarers Pension Plan. Instead, contributions are made to the Seafarers Health and Benefits Plan, and are subsequently re-allocated to the Seafarers Pension Plan at the discretion of the plan Trustee.
