28. Pension and other post-retirement benefits

Cameco maintains both defined benefit and defined contribution plans providing pension and post-retirement benefits to substantially all of its employees.

Under the defined pension benefit plans, Cameco provides benefits to retirees based on their length of service and final average earnings. The non-pension post-retirement plan covers such benefits as group life and supplemental health insurance to eligible employees and their dependants. The costs related to the non-pension post-retirement plans are charged to earnings in the period during which the employment services are rendered. However, these future obligations are not funded.

The effective date for the most recent valuations for funding purposes on the pension benefit plans is January 1, 2012. The next planned effective date for valuation for funding purposes of the pension benefit plans is set to be January 1, 2013.

A reconciliation of the funded status of the benefit plans to the financial statements is as follows:

  Pension Benefit Plans  Other Benefit Plans 
  2012  2011  2012  2011 
Fair value of plan assets, beginning of year $21,766  $27,135 
Expected return on assets 713  880     
Actuarial gain (loss) 166  (562)    
Employer contributions 10,015  1,875     
Benefits paid (10,949) (7,562)    
Fair value of plan assets, end of year $21,711  $21,766 
Defined benefit obligation, beginning of year $44,111  $35,518  16,276  13,355 
Current service cost 1,717  1,283  834  727 
Interest cost 1,819  1,948  737  747 
Actuarial loss (gain) 797  12,934  (1,550) 1,803 
Past service cost 688 
Benefits paid (10,949) (7,562) (980) (1,044)
Foreign exchange (10)
Defined benefit obligation, end of year $37,497  $44,111  15,317  16,276 
Funded status of plans - deficit $(15,786) $(22,345) (15,317) (16,276)
Unrecognized past service cost 455  571 
Defined benefit liability [note 18] $(15,786) $(22,345) (14,862) (15,705)

The actual return on plan assets for the pension benefit plans for the year ended December 31, 2012 was $878,800 (2011 - $318,400).

The percentages of the total fair value of assets in the pension plans for each asset category at December 31 were as follows:

  Pension Benefit Plans 
  2012  2011 
  1. (i) The defined benefit plan assets contain no material amounts of related party assets at December 31, 2012 and 2011 respectively.
  2. (ii) Relates to the value of the refundable tax account held by the Canada Revenue Agency. The refundable total is approximately equal to half of the sum of the realized investment income plus employer contributions less half of the benefits paid by the plan.
Asset Category (i)    
Equity securities 28% 22%
Fixed income 24% 20%
Other (ii) 48% 58%
Total 100% 100%

The following represents the components of net pension and other benefit expense included primarily as part of administration expense:

  Pension Benefit Plans  Other Benefit Plans 
  2012  2011  2012  2011 
Current service cost $1,717  $1,283  $834  $727 
Interest cost 1,819  1,948  737  747 
Expected return on plan assets (713) (880)
Past service cost 116  117 
Defined benefit expense 2,823  2,351  1,687  1,591 
Defined contribution pension expense 16,114  16,663 
Net pension and other benefit expense $18,937  $19,014  $1,687  $1,591 

The assumptions used to determine the Company’s defined benefit obligation and net pension and other benefit expense were as follows at December 31:

  Pension Benefit Plans  Other Benefit Plans 
  2012  2011  2012  2011 
Discount rate 4.0% 4.5% 4.0% 4.5%
Rate of compensation increase 3.0% 4.0%
Long-term rate of return on assets 5.9% 5.9%
Initial health care cost trend rate 7.0% 9.0%
Cost trend rate declines to 5.0%
Year the rate reaches its final level 2018 

The long-term rate of return on assets has been determined using an asset model that takes into account the allocation of assets among various asset classes, the expected rate of return on each asset class, the variability of returns and the correlation of returns among asset classes.

An increase of 1% in the assumed health care cost trend rate would increase the aggregate of the current service cost and interest cost components of other benefit expense by $30,400 and increase the defined benefit obligation for these plans by $292,300. A decrease of 1% in the assumed health care cost trend rate would decrease the aggregate of the current service cost and interest cost components of other benefit expense by $41,800 and decrease the defined benefit obligation for these plans by $366,500.

The total amount of actuarial losses (gains) recognized in other comprehensive income is:

  Pension Benefit Plans  Other Benefit Plans 
  2012  2011  2012  2011 
Balance at beginning of year $14,070  $574  $1,803 
Recognized during the year 631  13,496  (1,550)   1,803 
  $14,701  $14,070  $253    $1,803 

The following table presents historical information on both the pension and other benefit plans:

Fair value of plan assets $21,711  $21,766 
Defined benefit obligation 37,497  44,111  15,317    16,276 
Deficit in the plan $(15,786) $(22,345) (15,317) (16,276)
Experience adjustments arising on plan assets 0.8% (2.6)%
Experience adjustments arising on plan liabilities 2.1% 29.3% (10.1)% 11.1%

The following are the contributions expected to be paid to the plans during the annual period beginning after the end of the current reporting period:

Employer contribution to funded pension plans $281 
Benefits paid for unfunded benefit plans 788 
Cash contributions to defined contribution plans 16,598 

BPLP

BPLP has a funded registered pension plan and an unfunded supplemental pension plan. The funded plan is a contributory, defined benefit plan covering all employees up to the limits imposed by the Income Tax Act. The supplemental pension plan is a non-contributory, defined benefit plan covering all employees with respect to benefits that exceed the limits under the Income Tax Act. These plans are based on years of service and final average salary.

BPLP also has other post-retirement benefit and other post-employment benefit plans that provide for group life insurance, health care and long-term disability benefits. These plans are non-contributory.

The effective date for the most recent valuations for funding purposes on the pension benefit plans is January 1, 2012. The next planned effective date for valuation for funding purposes of the pension benefit plans is set to be January 1, 2013. The status of Cameco’s proportionate share (31.6%) of the benefit plans is shown below.

A reconciliation of the funded status of the benefit plans to the financial statements is as follows:

  Pension Benefit Plans  Other Benefit Plans

Defined benefit liability [note 18] $(343,041) $(258,801) (211,491) (209,562)

The actual return on plan assets for the pension benefit plans for the year ended December 31, 2012 was $72,680,000 (2011 - $24,184,000).

The percentages of the total fair value of assets in the pension plans for each asset category at December 31 were as follows:

  Asset Allocation  Target Allocation 
  2012  2011  2012  2011 
  1. (i) The defined benefit plan assets contain no material amounts of related party assets at December 31, 2012.
Asset Category (i)        
Equity securities 58% 55% 60% 60%
Fixed income 39% 43% 40% 40%
Cash 3% 2%
Total 100% 100% 100% 100%

The assets of the pension plan are managed on a going concern basis subject to legislative restrictions. The plan’s investment policy is to maximize returns within an acceptable risk tolerance. Pension assets are invested in a diversified manner with consideration given to the demographics of the plan participants.

The following represents the components of net pension and other benefit expense included primarily as part of cost of products and services sold:

  Pension Benefit Plans  Other Benefit Plans 
  2012  2011  2012  2011 
Current service cost $35,430  $26,752  $9,936  $9,312 
Interest cost 49,427  47,122  9,665  9,424 
Expected return on plan assets (54,036) (50,484)
Past service cost 450  450 
Net pension and other benefit expense $30,821  $23,390  $20,051  $19,186 

The assumptions used to determine BPLP’s defined benefit obligation and net pension and other benefit expense related to the pension benefit and other benefit plans were as follows:

  Pension Benefit Plans  Other Benefit Plans 
  2012  2011  2012  2011 
Discount rate 4.3% 4.8% 4.1% 4.6%
Rate of compensation increase 3.5% 3.5% 3.5% 3.5%
Long-term rate of return on assets 7.0% 7.0%
Initial health care cost trend rate 8.5% 9.0%
Cost trend rate declines to 5.0% 5.0%
Year the rate reaches its final level 2019  2019 

The overall expected rate of return is a weighted average of the expected returns of the various categories of plan assets held. The assessment of the expected returns is based on historical return trends with reference to market interest rates at the measurement date on high-quality debt instruments with cash flows that match the timing and amount of expected future benefit payments.

An increase of 1% in the assumed health care cost trend rate would increase the aggregate of the current service cost and interest cost components of other benefit expense by $4,188,000 and increase the defined benefit obligation for these plans by $37,521,000. A decrease of 1% in the assumed health care cost trend rate would decrease the aggregate of the current service cost and interest cost components of other benefit expense by $3,119,000 and decrease the defined benefit obligation for these plans by $28,780,000.

The total amount of actuarial losses (gains) recognized in other comprehensive income is:

  Pension Benefit Plans  Other Benefit Plans 
  2012  2011  2012  2011
