NOTE J – EMPLOYEE BENEFIT PLANS

Nonunion Defined Benefit Pension, Supplemental Benefit Pension and Postretirement Health Benefit Plans

The Company has a noncontributory defined benefit pension plan covering substantially all noncontractual employees hired before January 1, 2006. Noncontractual employees hired after 2005 participate in a defined contribution plan (see Defined Contribution Plans section within this Note). Benefits under the defined benefit pension plan are generally based on years of service and employee compensation. The Company’s contributions to the defined benefit pension plan are based upon the minimum funding levels required under provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Pension Protection Act of 2006 (the “PPA”), with the maximum contributions not to exceed deductible limits under the U.S. Internal Revenue Code (“IRC”).

The Company also has an unfunded supplemental benefit plan (“SBP”) for the purpose of supplementing benefits under the Company’s nonunion defined benefit pension plan for executive officers designated as participants in the SBP by the Company’s Board of Directors. The Compensation Committee of the Company’s Board of Directors (“Compensation Committee”) elected to close the SBP to new entrants and to place a cap on the maximum payment per participant to existing participants in the SBP effective January 1, 2006. In place of the SBP, eligible officers of the Company appointed after 2005 participate in a long-term cash incentive plan (see Long-Term Cash Incentive Plan section within this Note). Effective December 31, 2009, the Compensation Committee elected to freeze the accrual of benefits for remaining participants under the SBP. With the exception of early retirement penalties that may apply in certain cases, the valuation inputs for calculating the frozen SBP benefits to be paid to participants, including final average salary and the interest rate, were established at December 31, 2009.

The Company also sponsors an insured postretirement health benefit plan that provides supplemental medical benefits and dental benefits primarily to certain officers of the Company and certain subsidiaries. Effective January 1, 2011, retirees pay a portion of the premiums under the plan according to age and coverage levels. The amendment to the plan to implement retiree premiums resulted in an unrecognized prior service credit which was included in accumulated other comprehensive loss as of December 31, 2010.

The following table discloses the changes in benefit obligations and plan assets of the Company’s nonunion benefit plans for years ended December 31, the measurement date of the plans:

Nonunion Defined Benefit Pension Plan Assets

The Company establishes the expected long-term rate of return on nonunion defined benefit pension plan assets, which are held in trust, by considering the historical returns for the current mix of investments. In addition, consideration is given to the range of expected returns for the current pension plan investment mix provided by the plan’s investment advisor. This approach is intended to establish a long-term, nonvolatile rate. The Company’s long-term expected rate of return utilized in determining its 2013 nonunion defined benefit pension plan expense is expected to be 7.5%.

The overall objectives of the investment strategy for the Company’s nonunion defined benefit plan are to achieve a rate of return that over the long term will fund liabilities and provide for required benefits under the plan in a manner that satisfies the fiduciary requirements of ERISA. The investment strategy aims to maximize the long-term return on plan assets subject to an acceptable level of investment risk, liquidity risk, and long-term funding risk utilizing target asset allocations for investments. The plan’s long-term asset allocation policy is intended to protect or improve the purchasing power of plan assets and provide adequate diversification to limit the possibility of experiencing a substantial loss over a one-year period.

The weighted-average asset allocation of the Company’s nonunion defined benefit pension plan at December 31 is summarized in the following table:

	2012	2011
Equity Securities
Large Cap U.S. Equity	32.1%	31.1%
Mid Cap U.S. Equity	11.1	10.3
Small Cap U.S. Equity	11.1	10.5
International Equity	11.1	8.4
Emerging Market Equity	5.0	5.5

Income Securities

Floating Rate Loan Fund	4.0	4.1

Cash Equivalents
Cash and Cash Equivalents	3.2	13.5
	100.0%	100.0%

At December 31, 2012, the target allocations and acceptable ranges for the Company’s nonunion defined benefit pension plan assets were as follows:

	Target	Acceptable
	Allocation	Range
Equity Securities
Large Cap U.S. Equity	30.0%	25.0% – 35.0%
Mid Cap U.S. Equity	10.0%	8.0% – 12.0%
Small Cap U.S. Equity	10.0%	8.0% – 12.0%
International Equity	10.0%	8.0% – 12.0%
Emerging Market Equity	5.0%	3.0% – 7.0%

Income Securities
Debt Instruments	20.0%	15.0% – 30.0%
Floating Rate Loans	5.0%	3.0% – 7.0%

Cash Equivalents
Cash and Cash Equivalents	10.0%	0.0% – 15.0%

Investment balances and results are reviewed quarterly. Although investment allocations which fall outside the acceptable range at the end of any quarter are usually rebalanced based on the target allocation, the Company has the discretion to maintain cash or other short-term investments during periods of market volatility. Investment performance is generally compared to the three-to-five year performance of recognized market indices as well as analyzed for periods shorter than three years for each investment fund and over five years for the total fund.

Certain types of investments and transactions are prohibited or restricted by the Company’s written investment policy, including, but not limited to, borrowing of money; purchase of securities on margin; short sales; pledging, mortgaging, or hypothecating securities except loans of securities that are fully-collateralized; purchase or sale of futures, options, or derivatives for speculation or leverage; purchase or sale of commodities; or illiquid interests in real estate or mortgages. Historically, index funds have primarily been used for investments in equity and fixed income securities; however in recent years the Company has invested certain of these investments in actively managed portfolios. Beginning in 2009, the Company invested a portion of the plan’s income securities into an actively managed portfolio of short-term debt instruments. The objectives of this portfolio are to preserve principal and maintain an investment maturity structure that matches scheduled cash flows of benefit payments. In addition to the requirements of the investment policy, certain investment restrictions apply to the actively managed portfolio, including: minimum acceptable credit quality of securities; maximum maturity of investments of 7 years; and, at the time of purchase, no single issue or issuer other than U.S. government securities representing more than 5% of portfolio investments, and no more than 25% of the portfolio invested in BBB rated debt. Beginning in 2011, the Company invested a portion of the plan’s equity investments in an actively managed portfolio of mid-cap U.S. equity securities. In 2012, a portion of the plan’s income security investments were placed in a separate actively managed portfolio of short duration debt instruments, with certain investment restrictions, including: guidelines for allowable securities and certain maximum concentrations of investments; maintenance of an average effective duration period not to exceed 3 years; and minimum acceptable credit quality of securities.

Based upon currently available actuarial information, the Company’s required minimum contribution to its nonunion defined benefit pension plan in 2013 is estimated to be between $8 million and $10 million. The plan had an adjusted funding target attainment percentage (“AFTAP”) of 90% as of the January 1, 2012 valuation date. The AFTAP is determined by measurements prescribed by the IRC, which differ from the funding measurements for financial statement reporting purposes. The Company intends to make contributions to its nonunion defined benefit pension plan necessary to maintain an AFTAP of no less than 80%.

Deferred Compensation Plans

The Company has deferred salary agreements with certain executives for which liabilities of $5.5 million and $6.3 million were recorded as of December 31, 2012 and 2011, respectively. The deferred salary agreements include a provision that immediately vests all benefits and provides for a lump-sum payment upon a change in control of the Company. The Compensation Committee elected to close the deferred salary agreement program to new entrants effective January 1, 2006. In place of the deferred salary agreement program, officers appointed after 2005 participate in the Long-Term Cash Incentive Plan (see Long-Term Cash Incentive Plan section within this Note).

An additional benefit plan provides certain death and retirement benefits for certain officers and directors of an acquired company and its former subsidiaries. The Company had recorded liabilities of $1.2 million at December 31, 2012 and 2011 for future costs under this plan.

The Company maintains a Voluntary Savings Plan (“VSP”), a nonqualified deferred compensation program for the benefit of certain executives of the Company and certain subsidiaries. Eligible employees may defer receipt of a portion of their salary and incentive compensation into the VSP by making an election prior to the beginning of the year in which the salary compensation is payable and, for incentive compensation, by making an election at least six months prior to the end of the performance period to which the incentive relates. The Company credits participants’ accounts with applicable rates of return based on a portfolio selected by the participants from the investments available in the plan. The Company match related to the VSP was suspended beginning January 1, 2010. All deferrals, Company match, and investment earnings are considered part of the general assets of the Company until paid. Accordingly, the consolidated balance sheets reflect the fair value of the aggregate participant balances, based on quoted prices of the mutual fund investments, as both an asset and a liability of the Company. As of December 31, 2012 and 2011, VSP balances of $3.0 million and $3.6 million, respectively, were included in other long-term assets with a corresponding amount recorded in other long-term liabilities.

Defined Contribution Plans

The Company and its subsidiaries have various defined contribution 401(k) plans that cover substantially all employees. The plans permit participants to defer a portion of their salary up to a maximum of 69% as provided in Section 401(k) of the IRC. For certain participating subsidiaries, the Company has historically matched 50% of nonunion participant contributions up to the first 6% of annual compensation. The plans also allow for discretionary Company contributions determined annually. The Company match was suspended for 2010 and 2011 and was reinstated beginning January 1, 2012. The Company’s matching expense for the 401(k) plans totaled $3.8 million for 2012.

All employees who were participants in the nonunion defined benefit pension plan on December 31, 2005 continue in that plan. In place of the defined benefit pension plan, substantially all nonunion employees hired subsequent to December 31, 2005, participate in a defined contribution plan in which participants are fully vested after three years of service. The Company may make discretionary contributions to the defined contribution plan. No contributions were made to the plan for 2012. The Company recognized expense of $1.1 million and $0.8 million related to its contributions to the defined contribution plan in 2011 and 2010, respectively.

Long-Term Cash Incentive Plan

Pursuant to stockholder approval of the 2005 Ownership Incentive Plan, the Compensation Committee established a performance-based Long-Term Cash Incentive Plan. Participants in the Long-Term Cash Incentive Plan are officers of the Company or its subsidiaries who are not active participants in the deferred salary agreement program. The Long-Term Cash Incentive Plan incentive, which is generally earned over three years, is based in part upon a proportionate weighting of return on capital employed and in part upon the Company achieving specified levels of profitability, earnings per share growth, or shareholder returns compared to a peer group, as specifically defined in the Long-Term Cash Incentive Plan. Minimum performance requirements were not achieved for 2010, 2011, and 2012 and, as a result, no payments for earned incentives under the Long-Term Cash Incentive Plan were made for these years. Based on performance results during the open three year periods through December 31, 2012, no amounts have been accrued for future payments at December 31, 2012.

Other Plans

Other long-term assets include $41.6 million and $39.4 million at December 31, 2012 and 2011, respectively, in cash surrender value of life insurance policies. These policies are intended to provide funding for long-term nonunion benefit arrangements such as the Company’s SBP and deferred compensation plans. A portion of the Company’s cash surrender value of variable life insurance policies have investments, through separate accounts, in equity and fixed income securities and, therefore, are subject to market volatility. The Company recognized gains associated with changes in the cash surrender value and proceeds from life insurance policies of $2.1 million, $2.6 million, and $2.5 million, during 2012, 2011, and 2010, respectively.

Multiemployer Plans

Under the provisions of the Taft-Hartley Act, retirement and health care benefits for ABF’s contractual employees are provided by a number of multiemployer plans. Due to the inherent nature of multiemployer plans, there are risks associated with participation in these plans that differ from single-employer plans. ABF contributes to multiemployer pension and postretirement benefit plans monthly based generally on the time worked by its contractual employees, in accordance with its collective bargaining agreement with the IBT and other related supplemental agreements. ABF recognizes as expense the contractually required contribution for the period and recognizes as a liability any contributions due and unpaid. Other unrelated employers contribute to these multiemployer plans pursuant to their respective collective bargaining agreements. Assets contributed by an employer to a multiemployer plan are not segregated into a separate account and are not restricted to provide benefits only to employees of that contributing employer. If a participating employer to a multiemployer plan no longer contributes to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers. In the event of the termination of a multiemployer pension plan or if ABF withdraws from a multiemployer pension plan, under current law, the Company would have material liabilities for its share of the unfunded vested liabilities of each such plan. Multiemployer plans that enter reorganization status subject contributing employers to an increased contribution requirement, but will generally not require a contribution increase of more than 7% over the level required in the preceding year. ABF has not received notification of any plan termination, and ABF does not currently intend to withdraw from these plans. Therefore, the Company believes the likelihood of events that would require recognition of liabilities for its share of unfunded vested benefits is remote.

The Company intends to meet its obligations to the multiemployer plans under its current collective bargaining agreement with the IBT, which extends through March 31, 2013. In late December 2012, ABF began negotiations with the IBT for a new collective bargaining agreement applicable for the period subsequent to March 31, 2013. The negotiation of terms of the collective bargaining agreement is very complex and the final agreement may impact future contribution levels.

ABF currently contributes to 25 multiemployer pension plans, which vary in size and in funded status. The trust funds for these plans are administered by trustees, an equal number of whom generally are appointed by the IBT and certain management carrier organizations or other appointing authorities for employer trustees, as set forth in the fund’s trust agreements.

In 2006, the Pension Protection Act (the “PPA”) became law and together with related regulations established new minimum funding requirements for multiemployer pension plans. The PPA mandates that multiemployer pension plans that are below certain funded levels or that have projected funded deficiencies adopt a funding improvement plan or a rehabilitation program to improve the funded levels over a defined period of time. As defined by the PPA, plans in “critical status” (or in the red zone) are generally less than 65% funded, plans in “endangered status” (or in the yellow zone) are less than 80% funded, and plans in “neither endangered nor critical status” (or in the green zone) are at least 80% funded. The PPA also accelerates the timing of annual funding notices and requires additional disclosures from multiemployer pension plans if such plans fall below the required funded levels. Based on the most recent annual funding notices the Company has received, most of which are for plan years ended December 31, 2011, approximately 63% of ABF’s contributions to multiemployer pension plans, including the Central States, Southeast and Southwest Areas Pension Fund (the “Central States Pension Fund”) discussed below, are made to plans that are in “critical status” and approximately 12% of ABF’s contributions to multiemployer pension plans are made to plans that are in “endangered status,” as defined by the PPA.

In December 2008, the Worker, Retiree, and Employer Recovery Act of 2008 (the “Recovery Act”) became law. For plan years beginning October 1, 2008 through September 30, 2009, the Recovery Act allowed multiemployer plans the option to freeze their funded certification based on the funded status of the previous plan year. In addition, the Recovery Act provided multiemployer plans in endangered or critical status in plan years beginning in 2008 or 2009 a three-year extension of the plan’s funding improvement or rehabilitation period.

The Preservation of Access to Care for Medicare Beneficiaries and Pension Relief Act of 2010 (the “Pension Relief Act”) was signed into law in June 2010. The Pension Relief Act includes provisions that may provide funding relief for multiemployer pension plans that satisfy certain solvency requirements. The Company has not received information from the multiemployer plan administrators regarding the impact, if any, of the Pension Relief Act on the funded status of the multiemployer pension plans to which ABF contributes. Due to their funded positions, certain plans may not be eligible for funding relief provisions of the Pension Relief Act because of the solvency requirements under the law.

ABF’s participation in multiemployer pension plans is outlined in the table below. The multiemployer pension funds listed separately in the table represent funds which are individually significant to ABF based on the amount of plan contributions. The severity of a plan’s underfunded status was also considered in ABF’s analysis of individually significant funds to be separately disclosed. ABF’s current collective bargaining agreement with the IBT requires contributions to these multiemployer plans.

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.

For 2012, 2011, and 2010, 50% to 55% of ABF’s multiemployer pension contributions were made to the Central States Pension Fund. The Central States Pension Fund adopted a rehabilitation plan as a result of its actuarial certification for the plan year beginning January 1, 2008 which placed the Central States Pension Fund in critical status in accordance with the PPA. ABF’s current collective bargaining agreement complies with the rehabilitation plan which was adopted by the Central States Pension Fund prior to the April 1, 2008 effective date of the collective bargaining agreement. The Actuarial Certification of Plan Status as of January 1, 2010 certified that the Central States Pension Fund remained in critical status with a funded percentage of 63.4%. In accordance with PPA requirements, the Central States Pension Fund adopted an updated rehabilitation plan effective December 31, 2010, which implements additional measures to improve the plan’s funded level, including establishing a minimum retirement age and actuarially adjusting certain pre-age 65 benefits for participants who retire after July 1, 2011. The updated rehabilitation plan also effectively caps the required pension contribution rates at the current levels for the rate class applicable to the National Master Freight Agreement (the “NMFA”); however, any changes to scheduled contribution rate increases under the current labor agreement, which ends on March 31, 2013, would be subject to approval by the bargaining parties. The Central States Pension Fund remained in critical status as of January 1, 2012 with a funded percentage of 53.9%, and an amended rehabilitation plan was implemented effective December 31, 2011.

In 2005, the IRS granted an extension of the period of time over which the Central States Pension Fund amortizes unfunded liabilities by ten years subject to the condition that a targeted funding ratio will be maintained by the fund. Due, in part, to the decline in asset values associated with the investment losses in the financial markets during 2008, the funded level of the Central States Pension Fund dropped below the targeted funding ratio set forth as a condition of the ten-year amortization extension beginning with the January 1, 2009 actuarial valuation. However, the amortization extension granted by the IRS in 2005 expressly indicated that modifications of conditions would be considered in the event of unforeseen market fluctuations which cause the plan to fail the funded ratio condition for a certain plan year. Based on information currently available to the Company, the Central States Pension Fund has not received notice of revocation of the ten-year amortization extension granted by the IRS. In the unlikely event that the IRS revokes the extension, revocation would apply retroactively to the 2004 plan year, which would result in a material liability for ABF’s share of the resulting funded deficiency, the extent of which is currently unknown to the Company. The Company believes that the occurrence of events that would require recognition of liabilities for ABF’s share of a funded deficiency is remote.

Other multiemployer pension plans in which ABF participates, including the plans previously outlined in the table within this Note, have adopted or will have to adopt either a funding improvement plan or a rehabilitation program, depending on their current funded status as required by the PPA. The Company believes that the contribution rates under ABF’s collective bargaining agreement will comply with any rehabilitation plan that has been or may be adopted by the majority of the multiemployer pension plans in which ABF participates. If the contribution rates in the collective bargaining agreement fail to meet the requirements established by the rehabilitation or funding improvement plan required by the PPA for underfunded plans, the PPA would impose additional contribution requirements on ABF in the form of a surcharge of an additional 5% to 10%. However, under the current collective bargaining agreement, any surcharges that may be required by the PPA are covered by the contractual contribution rate and should not increase ABF’s overall contribution obligation.

ABF contributes to 44 multiemployer health and welfare plans which provide health care benefits for active employees and retirees covered under ABF’s labor agreements. ABF’s contributions to multiemployer health and welfare plans totaled $113.0 million, $112.1 million, and $103.1 million for the year ended December 31, 2012, 2011, and 2010, respectively. The contribution rate for health and welfare benefits increased by an average of 5.3%, 4.1%, and 3.8% primarily on August 1, 2012, 2011, and 2010, respectively, under ABF’s current collective bargaining agreement with the IBT. Other than these rate increases and changes in rates and time worked, there have been no other significant changes that affect the comparability of the 2012, 2011, and 2010 multiemployer health and welfare contributions.

The Company cannot determine with any certainty the minimum contributions which will be required under future collective bargaining agreements for its contractual employees that will become effective after March 31, 2013. Furthermore, the Company cannot predict future requirements or the related amounts thereof, if any, to make additional contributions to multiemployer funds to satisfy existing or future statutory or other contractual obligations, including any requirements to remedy plan funding deficiencies.
