NOTE 10. Pension and Postretirement Benefit Plans

 

3M has company-sponsored retirement plans covering substantially all U.S. employees and many employees outside the United States. In total, 3M has over 70 plans in 25 countries. Pension benefits associated with these plans generally are based on each participant's years of service, compensation, and age at retirement or termination. The U.S. defined-benefit pension plan was closed to new participants effective January 1, 2009. The Company also provides certain postretirement health care and life insurance benefits for substantially all of its U.S. employees who reach retirement age while employed by the Company. Most international employees and retirees are covered by government health care programs. The cost of company-provided postretirement health care plans for international employees is not material and is combined with U.S. amounts in the tables that follow.

 

The Company also sponsors employee savings plans under Section 401(k) of the Internal Revenue Code. These plans are offered to substantially all regular U.S. employees. Effective January 1, 2010, substantially all Company contributions to the plans are made in cash. During 2008 the Board of Directors approved various changes to the employee savings plans. For substantially all employees hired prior to January 1, 2009, employee 401(k) contributions of up to 6% of eligible compensation are matched at rates of 60% or 75%, depending on the plan the employee participated in. Employees hired on or after January 1, 2009 receive a cash match of 100% for employee 401(k) contributions of up to 6% of eligible compensation and also receive an employer retirement income account cash contribution of 3% of the participant's total eligible compensation. All contributions are invested in a number of investment funds pursuant to their elections. U.S. expenses related to employer contributions to these plans were $124 million, and $109 million and $97 million for 2012, 2011 and 2010, respectively. Various international countries also participate in defined contribution plans. International expenses related to employer contributions to these plans were $58 million, $54 million and $36 million for 2012, 2011 and 2010, respectively.

 

The Company's defined benefit pension funding policy is to deposit with independent trustees amounts allowable by law. Trust funds and deposits with insurance companies are maintained to provide pension benefits to plan participants and their beneficiaries. There are no plan assets in the non-qualified plan due to its nature. For its U.S. postretirement health care and life insurance benefit plans, the Company has set aside amounts at least equal to annual benefit payments with an independent trustee.

 

In August 2006, the Pension Protection Act (PPA) was signed into law in the U.S. The PPA transition rules increased the funding target for defined benefit pension plans to 100% of the target liability by 2011. 3M's U.S. qualified defined benefit plan does not have a mandatory cash contribution because the Company has a significant credit balance from previous discretionary contributions that can be applied to any PPA funding requirements.

 

In the fourth quarter of 2010, the Company made further changes to its U.S. postretirement benefit plans. As a result of these changes, the Company will transition all current and future retirees to the savings account benefits-based plan announced in 2008. These changes become effective beginning January 1, 2013, for all Medicare eligible retirees and their Medicare eligible dependents and January 1, 2015, for all non-Medicare eligible retirees and their eligible dependents.

In the second quarter of 2010, 3M's Brazilian subsidiary received approval from the government in Brazil to freeze its defined benefit pension plan. Effective March 31, 2010, participants in this subsidiary's pension plan no longer accrue additional pension benefits. As a result, the Company recorded a $22 million curtailment gain in the second quarter of 2010.

 

In December 2011, the Company began offering a voluntary early retirement incentive program to certain eligible participants of its U.S. pension plans who meet age and years of pension service requirements. The eligible participants who accepted the offer and retired on February 1, 2012 received an enhanced pension benefit. Pension benefits were enhanced by adding one additional year of pension service and one additional year of age for certain benefit calculations. 616 participants accepted the offer and retired on February 1, 2012. As a result, the Company incurred a $26 million charge related to these special termination benefits in the first quarter of 2012.

 

Effective July 1, 2012, 3M Canada closed its pension plans for salaried employees to new participants. The change did not trigger a plan remeasurement and therefore there is no immediate impact to the liability and expense.

 

3M was informed during the first quarter of 2009 that the general partners of WG Trading Company, in which 3M's benefit plans hold limited partnership interests, are the subject of a criminal investigation as well as civil proceedings by the SEC and CFTC (Commodity Futures Trading Commission). In March 2011, over the objections of 3M and six other limited partners of WG Trading Company, the district court judge ruled in favor of the court appointed receiver's proposed distribution plan. In April 2011, the 3M benefit plans received their share under the court-ordered distribution plan. 3M and six other limited partners of WG Trading Company have appealed the court's order to the United States Court of Appeals for the Second Circuit. The benefit plan trustee holdings of WG Trading Company interests were adjusted to reflect the decreased estimated fair market value, inclusive of estimated insurance proceeds, as of the annual measurement dates. The Company has insurance that it believes, based on what is currently known, will result in the recovery of a portion of the decrease in original asset value. As of the 2012 measurement date these holdings represented less than one percent of 3M's fair value of total plan assets. 3M currently believes that the resolution of these events will not have a material adverse effect on the consolidated financial position of the Company.

The following tables include a reconciliation of the beginning and ending balances of the benefit obligation and the fair value of plan assets as well as a summary of the related amounts recognized in the Company's consolidated balance sheet as of December 31 of the respective years. 3M also has certain non-qualified unfunded pension and postretirement benefit plans, inclusive of plans related to supplement/excess benefits for employees impacted by particular relocations and other matters, that individually and in the aggregate are not significant and which are not included in the tables that follow. The obligations for these plans are included within other liabilities in the Company's consolidated balance sheet and aggregated less than $40 million as of both December 31, 2012 and 2011.

The Company is in the process of transitioning all current and future retirees to the savings account benefits-based plan announced in 2008. The contributions provided by the Company to the health savings accounts increase three percent per year. Therefore, the Company no longer has material exposure to health care cost inflation.

The Company determines the discount rate used to measure plan liabilities as of the December 31 measurement date for the pension and postretirement benefit plans, which is also the date used for the related annual measurement assumptions. The discount rate reflects the current rate at which the associated liabilities could be effectively settled at the end of the year. The Company sets its rate to reflect the yield of a portfolio of high quality, fixed-income debt instruments that would produce cash flows sufficient in timing and amount to settle projected future benefits. Using this methodology, the Company determined a discount rate of 4.14% for pension and 4.00% for postretirement benefits to be appropriate for its U.S. plans as of December 31, 2012, which is a decrease of 0.01 percentage points and 0.04 percentage points, respectively, from the rates used as of December 31, 2011. For the international pension and postretirement plans the discount rates also reflect the current rate at which the associated liabilities could be effectively settled at the end of the year. If the country has a deep market in corporate bonds the Company matches the expected cash flows from the plan either to a portfolio of bonds that generate sufficient cash flow or a notional yield curve generated from available bond information. In countries that do not have a deep market in corporate bonds, government bonds are considered with a risk premium to approximate corporate bond yields.

 

For the U.S. qualified pension plans, the Company's assumption for the expected return on plan assets was 8.25% in 2012. The Company is lowering the 2013 expected return on plan assets for its U.S. pension plan by 0.25 percentage points to 8.00%. This will increase the 2013 expected pension expense by approximately $33 million. Projected returns are based primarily on broad, publicly traded equity and fixed-income indices and forward-looking estimates of active portfolio and investment management. As of December 31, 2012, the Company's 2013 expected long-term rate of return on U.S. plan assets is based on an asset allocation assumption of 30% global equities, with an expected long-term rate of return of 7.58%; 16% private equities, with an expected long-term rate of return of 12.58%; 33% fixed-income securities, with an expected long-term rate of return of 3.72%; 16% absolute return investments independent of traditional performance benchmarks, with an expected long term return of 6.43%; and 5% commodities, with an expected long-term rate of return of 6.08%. The Company expects additional positive return from active investment management. These assumptions result in an 8.00% expected rate of return on an annualized basis in 2013. The actual rate of return on plan assets in 2012 was 13.6%. In 2011 the plan earned a rate of return of 8.7% and in 2010 earned a return of 14.4%. The average annual actual return on the plan assets over the past 10 and 25 years has been 10.5% and 10.6%, respectively. Return on assets assumptions for international pension and other post-retirement benefit plans are calculated on a plan-by-plan basis using plan asset allocations and expected long-term rate of return assumptions.

 

During 2012, the Company contributed $1.079 billion to its U.S. and international pension plans and $67 million to its postretirement plans. During 2011, the Company contributed $517 million to its U.S. and international pension plans and $65 million to its postretirement plans. In 2013, the Company expects to contribute an amount in the range of $400 million to $600 million of cash to its U.S. and international retirement plans. The Company does not have a required minimum cash pension contribution obligation for its U.S. plans in 2013. Therefore, the amount of the anticipated discretionary contribution could vary significantly depending on the U.S. plans' funded status and the anticipated tax deductibility of the contribution. Future contributions will also depend on market conditions, interest rates and other factors.

Plan Asset Management

 

3M's investment strategy for its pension and postretirement plans is to manage the funds on a going-concern basis. The primary goal of the funds is to meet the obligations as required. The secondary goal is to earn the highest rate of return possible, without jeopardizing its primary goal, and without subjecting the Company to an undue amount of contribution rate volatility. Fund returns are used to help finance present and future obligations to the extent possible within actuarially determined funding limits and tax-determined asset limits, thus reducing the level of contributions 3M must make. The investment strategy has used long duration cash and derivative instruments to offset a significant portion of the interest rate sensitivity of U.S. pension liabilities. In addition, credit risk is managed through mandates for public securities and maximum issuer limits that are established and monitored on a regular basis.

 

Normally, 3M does not buy or sell any of its own stock as a direct investment for its pension and other postretirement benefit funds. However, due to external investment management of the funds, the plans may indirectly buy, sell or hold 3M stock. The aggregate amount of the shares would not be considered to be material relative to the aggregate fund percentages.

 

The discussion that follows references the fair value measurements of certain assets in terms of levels 1, 2 and 3. See Note 12 for descriptions of these levels. While the company believes the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

 

U.S. Pension Plans Assets

 

In order to achieve the investment objectives in the U.S. pension plans, the investment policy includes a target strategic asset allocation. The investment policy allows some tolerance around the target in recognition that market fluctuations and illiquidity of some investments may cause the allocation to a specific asset class to stray from the target allocation, potentially for long periods of time. Acceptable ranges have been designed to allow for deviation from long-term targets and to allow for the opportunity for tactical over- and under-weights. The portfolio will normally be rebalanced when the quarter-end asset allocation deviates from acceptable ranges. The allocation is reviewed regularly by the named fiduciary of the plans.

 

The fair values of the assets held by the U.S. pension plans by asset class are as follows:

Publicly traded equities are valued at the closing price reported in the active market in which the individual securities are traded. Index funds, including Europe, Australasia, and Far East (EAFE) funds, are valued at the net asset value (NAV) as determined by the custodian of the fund. The NAV is based on the fair value of the underlying assets owned by the fund, minus its liabilities then divided by the number of units outstanding. Long/short equity interests are valued using the most recent general partner statement of fair value, updated for any subsequent partnership interests' cash flows or expected changes in fair value.

       

Fixed income includes derivative instruments such as credit default swaps, interest rate swaps and futures contracts that are used to help manage risks. U.S. government and government agency bonds and notes are valued at the closing price reported in the active market in which the individual security is traded. Corporate bonds and notes, asset backed securities and collateralized mortgage obligations are valued at either the yields currently available on comparable securities of issuers with similar credit ratings or valued under a discounted cash flows approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks. Private placement funds are valued using the most recent general partner statement of fair value, updated for any subsequent partnership interests' cash flows or expected changes in fair value. Swaps and derivative instruments are valued by the custodian using closing market swap curves and market derived inputs.

 

The private equity portfolio is a diversified mix of partnership interests including buyouts, derivative instruments, direct investments, distressed debt, growth equity, mezzanine, real estate and venture capital investments. Partnership interests are valued using the most recent general partner statement of fair value, updated for any subsequent partnership interests' cash flows or expected changes in fair value.

 

Absolute return consists primarily of private partnership interests in hedge funds, hedge fund of funds and bank loan funds. Partnership interests are valued using the NAV as determined by the administrator or custodian of the fund. Hedge fund partnership interests, which have a redemption right and are past any lock-up redemption period, are classified as level 2. A hedge fund was restructured during 2012, extending the lock-up redemption period, and therefore was moved to level 3 during 2012.

 

Commodities consist of commodity-linked notes and commodity-linked derivative contracts designed to deliver investment returns similar to the Goldman Sachs Commodities Index (GSCI) or Dow Jones UBS Commodity index returns. Commodities are valued at closing prices determined by calculation agents for outstanding transactions.

 

Other items to reconcile to fair value of plan assets include the net of insurance receivables for WG Trading Company, interest receivables, amounts due for securities sold, amounts payable for securities purchased and interest payable.

International Pension Plans Assets

 

Outside the U.S., pension plan assets are typically managed by decentralized fiduciary committees. The disclosure below of asset categories is presented in aggregate for over 65 plans in 24 countries; however, there is significant variation in policy asset allocation from country to country. Local regulations, local funding rules, and local financial and tax considerations are part of the funding and investment allocation process in each country. 3M's Treasury group provides standard funding and investment guidance to all international plans with more focused guidance to the larger plans.

 

Each plan has its own strategic asset allocation. The asset allocations are reviewed periodically and rebalanced when necessary.

 

The fair values of the assets held by the international pension plans by asset class are as follows:

Equities consist primarily of mandates in public equity securities managed to the Morgan Stanley Capital All Country World Index. Publicly traded equities are valued at the closing price reported in the active market in which the individual securities are traded.

 

Fixed Income investments include domestic and foreign government, corporate, mortgage backed and other debt. Governments, corporate bonds and notes and mortgage backed securities are valued at the closing price reported if traded on an active market or at yields currently available on comparable securities of issuers with similar credit ratings or valued under a discounted cash flows approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.

 

Private equity funds consist of both active and passive mandates. Partnership interests are valued using the most recent general partner statement of fair value, updated for any subsequent partnership interests' cash flows or expected changes in fair value. Real estate consists of property funds and REITS (Real Estate Investment Trusts). Property funds are valued using the most recent partnership statement of fair value, updated for any subsequent partnership interests' cash flows. REITS are valued at the closing price reported in the active market in which it is traded.

 

Absolute return consists of private partnership interests in hedge funds, insurance contracts, derivative instruments, hedge fund of funds, and bank loan funds. Insurance consists of insurance contracts, which are valued using cash surrender values which is the amount the plan would receive if the contract was cashed out at year end. Derivative instruments consist of interest rate swaps that are used to help manage risks. Hedge funds are valued at the NAV as determined by the independent administrator or custodian of the fund.

 

Other items to reconcile to fair value of plan assets include the net of interest receivables, amounts due for securities sold, amounts payable for securities purchased and interest payable.

Postretirement Benefit Plans Assets

 

In order to achieve the investment objectives in the U.S. postretirement plan, the investment policy includes a target strategic asset allocation. The investment policy allows some tolerance around the target in recognition that market fluctuations and illiquidity of some investments may cause the allocation to a specific asset class to stray from the target allocation, potentially for long periods of time. Acceptable ranges have been designed to allow for deviation from long-term targets and to allow for the opportunity for tactical over- and under-weights. The portfolio will normally be rebalanced when the quarter-end asset allocation deviates from acceptable ranges. The allocation is reviewed regularly by the named fiduciary of the plan.

 

The fair values of the assets held by the postretirement benefit plans by asset class are as follows:
