PENSIONS AND OTHER POSTRETIREMENT BENEFITS Pension Benefits We sponsor several single-employer defined benefit pension plans  the majority of which have been frozen. We  also participate in joint Company and Guild-sponsored plans covering employees of The New York Times Newspaper  Guild  including The Newspaper Guild of New York - The New York Times Pension Fund  which was frozen and  replaced with a new defined benefit pension plan  The Guild-Times Adjustable Pension Plan. The table below includes the liability for all of these plans. Our Company-sponsored defined benefit pension plans include qualified plans (funded) as well as non- qualified plans (unfunded). These plans provide participating employees with retirement benefits in accordance with  benefit formulas detailed in each plan. All of our non-qualified plans  which provide enhanced retirement benefits to  select employees  are currently frozen  except for a foreign-based pension plan discussed below. The New York Times  Newspaper Guild pension plan is a qualified plan and is also included in the table below. We also have a foreign-based pension plan for certain non-U.S. employees (the “foreign plan”). The information  for the foreign plan is combined with the information for U.S. non-qualified plans. The benefit obligation of the  foreign plan is immaterial to our total benefit obligation. The funded status of our qualified and non-qualified pension plans as of December 28  2014 is as follows: We made contributions of approximately $15 million to certain qualified pension plans in 2014. We expect  contributions to total approximately $9 million to satisfy minimum funding requirements in 2015. Pension expense is calculated using a number of actuarial assumptions  including an expected long-term rate of  return on assets (for qualified plans) and a discount rate. Our methodology in selecting these actuarial assumptions is  discussed below. In determining the expected long-term rate of return on assets  we evaluated input from our investment  consultants  actuaries and investment management firms  including our review of asset class return expectations  as  well as long-term historical asset class returns. Projected returns by such consultants and economists are based on  broad equity and bond indices. Our objective is to select an average rate of earnings expected on existing plan assets  and expected contributions to the plan during the year. The expected long-term rate of return determined on this  basis was 7.00% at the beginning of 2014. Our plan assets had an average rate of return of approximately 14.3% in  2014 and an average annual return of approximately 12.6% over the three-year period 2012-2014. We regularly review  our actual asset allocation and periodically rebalance our investments to meet our investment strategy. The value (“market-related value”) of plan assets is multiplied by the expected long-term rate of return on  assets to compute the expected return on plan assets  a component of net periodic pension cost. The market-related  value of plan assets is a calculated value that recognizes changes in fair value over three years. Based on the composition of our assets at the end of the year  we estimated our 2015 expected long-term rate of  return to be 7.00%  equal to 2014. If we had decreased our expected long-term rate of return on our plan assets by 50  THE NEW YORK TIMES COMPANY – P. 49 (In thousands) December 28  2014 December 29  2013 Pension and other postretirement liabilities $ 728 577 $ 563 162 Total liabilities $ 1 838 125 $ 1 726 018 Percentage of pension and other postretirement liabilities to total liabilities 40% 33% GLYPH<160> December 28  2014 (In thousands) Qualified Plans Non-Qualified Plans All Plans Pension obligation $ 2 101 573 $ 267 824 $ 2 369 397 Fair value of plan assets 1 837 250 GLYPH<151> 1 837 250 Pension underfunded/unfunded obligation  net $ 264 323 $ 267 824 $ 532 147
