Other Liquidity Items Cash payments required for long-term debt maturities, rental payments under noncancellable operating leases, purchase obligations and other commitments in effect at December 31, 2007, are summarized in the following table:
## Table 0 ##
(a) Amounts reported in local currencies have been translated at the year-end exchange rates.
(b) For variable rate facilities, amounts are based on interest rates in effect at year end and do not contemplate the effects of hedging instruments.
(c) The company’s purchase obligations include contracted amounts for aluminum, steel, plastic resin and other direct materials.
Also included are commitments for purchases of natural gas and electricity, aerospace and technologies contracts and other less significant items.
In cases where variable prices and/or usage are involved, management’s best estimates have been used.
Depending on the circumstances, early termination of the contracts may not result in penalties and, therefore, actual payments could vary significantly.
Contributions to the company’s defined benefit pension plans, not including the unfunded German plans, are expected to be $49 million in 2008.
This estimate may change based on plan asset performance.
Benefit payments related to these plans are expected to be $66 million, $70 million, $74 million, $77 million and $82 million for the years ending December 31, 2008 through 2012, respectively, and a total of $473 million for the years 2013 through 2017.
Payments to participants in the unfunded German plans are expected to be approximately $26 million in each of the years 2008 through 2012 and a total of $136 million for the years 2013 through 2017.
In accordance with United Kingdom pension regulations, Ball has provided an ￡8 million guarantee to the plan for its defined benefit plan in the United Kingdom.
If the company’s credit rating falls below specified levels, Ball will be required to either: (1) contribute an additional ￡8 million to the plan; (2) provide a letter of credit to the plan in that amount or (3) if imposed by the appropriate regulatory agency, provide a lien on company assets in that amount for the benefit of the plan.
The guarantee can be removed upon approval by both Ball and the pension plan trustees.
Our share repurchase program in 2007 was $211.3 million, net of issuances, compared to $45.7 million net repurchases in 2006 and $358.1 million in 2005.
The net repurchases included the $51.9 million settlement on January 5, 2007, of a forward contract entered into in December 2006 for the repurchase of 1,200,000 shares.
However, the 2007 net repurchases did not include a forward contract entered into in December 2007 for the repurchase of 675,000 shares.
The contract was settled on January 7, 2008, for $31 million in cash.
On December 12, 2007, in a privately negotiated transaction, Ball entered into an accelerated share repurchase agreement to buy $100 million of its common shares using cash on hand and available borrowings.
The company advanced the $100 million on January 7, 2008, and received approximately 2 million shares, which represented 90 percent of the total shares as calculated using the previous day’s closing price.
The exact number of shares to be repurchased under the agreement, which will be determined on the settlement date (no later than June 5, 2008), is subject to an adjustment based on a weighted average price calculation for the period between the initial purchase date and the settlement date.
The company has the option to settle the contract in either cash or shares.
Including the settlements of the forward share purchase contract and the accelerated share repurchase agreement, we expect to repurchase approximately $300 million of our common shares, net of issuances, in 2008.
Annual cash dividends paid on common stock were 40 cents per share in 2007, 2006 and 2005.
Total dividends paid were $40.6 million in 2007, $41 million in 2006 and $42.5 million in 2005.
?
Medium-duty truck and bus sales decreased primarily due to lower demand in the Brazilian truck market due to pre- buy activity in the second half of 2011 ahead of the implementation of Euro V emission regulations in the first quarter of 2012 and one of our customers replacing our B6.7 engine with a proprietary engine in 2012.
The B6.7 engine replacement was partially offset by the 2012 launch of our ISF and 9 liter engines in new light-duty on-highway and medium-duty truck applications, respectively, with this same customer.
The decrease was further offset by improved demand in North American markets.
The decreases above were partially offset by the following: ?
Heavy-duty truck engine sales increased due to growth in the North American on-highway markets in the first half of the year, primarily as a result of the replacement of aging fleets.  ?
Light-duty automotive and RV sales increased primarily due to a 37 percent improvement in units shipped to Chrysler.
Total on-highway-related sales for 2012 were 59 percent of total engine segment sales, compared to 56 percent in 2011.
Segment EBIT Engine segment EBIT decreased versus 2011, primarily due to lower gross margin, lower equity, royalty and interest income from investees, higher research, development and engineering expenses and higher selling, general and administrative expenses.
Engine segment EBIT for 2012 included restructuring and other charges of $20 million in the fourth quarter.
Major components of EBIT and related changes to segment EBIT and EBIT as a percentage of sales were as follows
## Table 1 ##
The decrease in gross margin versus 2011 was primarily due to lower volumes and restructuring and other charges, which was partially offset by improved price realization, lower material costs, favorable product mix and improved product coverage.
The increase in selling, general and administrative expenses was primarily due to increased headcount to support our strategic growth initiatives launched prior to a number of markets unexpectedly slowing in mid-2012, partially offset by decreased variable compensation expense.
The increase in research, development and engineering expenses was primarily due to new product development spending and increased headcount to support our strategic growth initiatives.
The decrease in equity, royalty and interest income from investees was primarily due to weaker demand for on-highway products at DCEC.
Components Segment Results Financial data for the Components segment was as follows:

experienced in 2008 as a result of the credit crisis and related market recession.
Based on the historical returns and forwardlooking return expectations, we believe an investment return assumption of 7.5 percent per year in 2014 for U. S.  pension assets is reasonable.
The methodology used to determine the rate of return on pension plan assets in the U. K.  was based on establishing an equityrisk premium over current long-term bond yields adjusted based on target asset allocations.
As of December 31, 2013, based upon our target asset allocations, it is anticipated that our U. K.  investment policy will generate an average annual return over the 20-year projection period equal to or in excess of 5.6 percent approximately 50 percent of the time while returns of 6.5 percent or greater are anticipated 25 percent of the time.
We expect additional positive returns from active investment management.
The one-year return for our U. K.  plan was 10.9 percent for 2013, and similar to our U. S.  plan, the 2008 market related deterioration in our plan assets has been eliminated.
Our strategy with respect to our investments in pension plan assets is to be invested with a long-term outlook.
Therefore, the risk and return balance of our asset portfolio should reflect a longterm horizon.
Based on the historical returns and forward-looking return expectations, we believe an investment return assumption of 5.8 percent in 2014 for U. K.  pension assets is reasonable.
Our pension plan asset allocations at December 31, 2013 and 2012 and target allocation for 2014 are as follows:
## Table 3 ##
The differences between the actual return on plan assets and expected long-term return on plan assets are recognized in the asset value used to calculate net periodic expense over five years.
The table below sets forth the expected return assumptions used to develop our pension cost for the period 2011-2013 and our expected rate of return for 2014.
