Employee Retirement Plans

Employee Retirement Plans

The Company sponsors defined benefit plans and defined contribution profit sharing plans that provide retirement income and death benefits for eligible employees. The annual measurement date of the benefit obligations, fair value of plan assets, and funded status is December 31.

Actuarial Assumptions

	Year Ended December 31,
	2012	2011	2010
Assumptions used to determine benefit obligations at the annual measurement date were:
Obligation discount rate	4.25%	5.40%	5.90%
Compensation increase rate	4.00%	3.00%	3.00%
Assumptions used to determine net periodic benefit costs were:
Obligation discount rate	5.40%	5.90%	6.10%
Long-term rate of return on plan assets	7.75%	7.75%	7.75%
Compensation increase rate	3.00%	3.00%	3.00%

The obligation discount rate assumption is determined by deriving a single discount rate from a theoretical settlement portfolio of high quality corporate bonds sufficient to provide for the plans' projected benefit payments. The expected long-term rate of return on plan assets is an assumption reflecting the anticipated weighted average rate of earnings on the portfolio over the long-term. To arrive at this rate, we developed estimates based upon the anticipated performance of the assets in its portfolio. The compensation increase rate pertains solely to the pension plan of the Company's Inland Barge segment as the accrued benefits of the Company's remaining pension plans were frozen in 2009.

The Company's pension investment strategies have been developed as part of a comprehensive asset/liability management process that considers the relationship between both the assets and liabilities of the plans. These strategies consider not only the expected risk and returns on plan assets, but also the actuarial projections of liabilities, projected contributions, and funded status. The equity allocation is heavily weighted toward domestic large capitalized companies. There is also a lesser exposure to domestic small/mid cap companies, international equities, and domestic real estate investment trusts. The fixed income allocation is weighted toward domestic long duration bonds. There is also a lesser exposure to domestic high yield and emerging market sovereign debt. This asset mix is designed to meet the longer-term obligations of the plan as projected by actuarial studies.

The principal pension investment strategies include asset allocation and active asset management. The range of target asset allocations has been determined after giving consideration to the expected returns of each asset category, the expected performance of each asset category, the volatility of the asset returns over time, and the complementary nature of the asset mix within the portfolio. Each asset category is managed by external money managers with the objective of generating returns that exceed market-based benchmarks.

The pension plan assets are valued at fair value. The following is a description of the valuation methodologies used in determining fair value, including the general classification of such instruments pursuant to the valuation hierarchy as described further in Note 3 Fair Value Accounting.

Temporary cash investments - These investments consist of U.S. dollars held in master trust accounts with the trustee. These temporary cash investments are classified as Level 1 instruments.

Common trust funds - Common trust funds are comprised of shares or units in commingled funds that are not publicly traded. The underlying assets in these funds are publicly traded on exchanges and price quotes for the assets held by these funds are readily available. Holdings of common trust funds are classified as Level 2 investments.

Registered investment companies - Registered investment companies are mutual funds registered with the Securities and Exchange Commission. Mutual fund shares are traded actively on public exchanges. The share prices for mutual funds are published at the close of each business day. Holdings of mutual funds are classified as Level 1 investments.

Cash Flows

Employer contributions for the year ending December 31, 2013 are expected to be $18.9 million for the defined benefit plans compared to $17.3 million contributed during 2012. Employer contributions to the 401(k) plans and the Supplemental Profit Sharing Plan for the year ending December 31, 2013 are expected to be $11.9 million compared to $9.3 million, $8.2 million and $7.9 million during 2012, 2011, and 2010, respectively.

Benefit payments expected to be paid during the next ten years are as follows:

	Years ending December 31,
	(in millions)
2013	$	15.8
2014	16.8
2015	18.0
2016	19.2
2017	20.6
2018-2022	122.5

Participants in the Pension Plan are eligible to receive future retirement benefits through a company-funded annual retirement contribution provided through the Profit Sharing Plan for Employees of Trinity Industries, Inc. and Certain Affiliates. The contribution ranges from one to three percent of eligible compensation based on service. Both the annual retirement contribution and the company matching contribution are discretionary, requiring board approval, and are made annually with the investment of the funds directed by the participants.
