Table Heading Definitions

(a)    The “EIN/Pension Plan Number” column provides the Federal Employer Identification Number (EIN) and the three-digit plan number, if applicable.

(b) Unless otherwise noted, the most recent PPA zone status available in 2012 and 2011 is for the plan’s year-end status at December 31, 2011 and 2010, respectively. The zone status is based on information ABF received from the plan and is certified by the plan’s actuary.

(c) The “FIP/RP Status Pending/Implemented” column indicates if a financial improvement plan (FIP) or a rehabilitation plan (RP), if applicable, is pending or has been implemented.

(d) Contribution amounts reflect payments made in the respective year and differ from amounts expensed during the year, which are disclosed in total within this Note.

(e)    The surcharge column indicates if a surcharge was paid by the employer to the plan.

(1) ABF was listed by the plan as providing more than 5% of the total contributions to the plan for the plan years ended December 31, 2011 and 2010.

(2) Information for this fund was obtained from the annual funding notice, other notices received from the plan, and the Form 5500 filed for the plan years ended December 31, 2011 and December 31, 2010.

(3) Adopted a rehabilitation plan effective March 25, 2008 and updated rehabilitation plans effective December 31, 2010 (as further discussed in this Note) and December 31, 2011. Utilized amortization extension effective December 31, 2003.

(4) Utilized amortization extension to calculate the zone status beginning with the January 1, 2011 actuarial valuation.

(5) Certified as “endangered” status for the plan year beginning January 1, 2012. The funding improvement plan was not formally adopted as of December 31, 2012.

(6) Pension Protection Act zone status relates to plan years February 1, 2011 - January 31, 2012 and February 1, 2010 – January 31, 2011.

(7) ABF was listed by the plan as providing more than 5% of the total contributions to the plan for the plan years ended January 31, 2012 and 2011.

(8) Information for this fund was obtained from the annual funding notice, other notices received from the plan, and the Form 5500 filed for the plan years ended January 31, 2012 and January 31, 2011.

(9) Certified as “endangered” status for the plan year beginning February 1, 2010. The Plan adopted a funding improvement plan effective December 25, 2010. The Plan was subsequently certified for the plan year beginning February 1, 2011 as being in “neither endangered nor critical” status. Therefore, it never implemented the Funding Improvement Plan as required for plans certified as “endangered.”

(10) Contribution levels can be impacted by several factors such as changes in business levels and the related time worked by contractual employees, contractual rate increases for pension benefits, and the specific funding structure, which differs among funds. The pension contribution rate for contractual employees increased an average of 2.3%, 3.6%, and 9.6% effective primarily on August 1, 2012, 2011, and 2010, respectively. For the contractual increases effective August 1, 2012 and 2011, the plan’s Supplemental Negotiating Committee approved no increase for Central States Pension Fund. The Supplemental Negotiating Committee for the Western Conference of Teamsters Pension Plan approved no pension increase effective August 1, 2012. The year-over-year changes in multiemployer pension plan contributions presented above were also influenced by changes in ABF’s business levels.
