10. Other Postretirement Benefits Net Periodic Other Postretirement Benefit Expense/(Income) We provide health benefits to retired employees (and their eligible dependents) who meet the definition of an  eligible participant and certain age and service requirements, as outlined in the plan document. While we offer pre- age 65 retiree medical coverage to employees who meet certain retiree medical eligibility requirements, we no longer  provide post-age 65 retiree medical benefits for employees who retired on or after March 1, 2009. We also contribute to  a postretirement plan for Guild employees of New York Times Newspaper under the provisions of a collective  bargaining agreement. We accrue the costs of postretirement benefits during the employees’ active years of service  and our policy is to pay our portion of insurance premiums and claims from our assets. The components of net periodic postretirement benefit expense/(income) were as follows: In 2012, we sold the Regional Media Group. The sale significantly reduced the expected years of future service  for current employees, resulting in a remeasurement and curtailment of a postretirement benefit plan. We recognized  a curtailment gain of $27.2 million in the first quarter of 2012, which is included in the gain on the sale within  “(Loss)/income from discontinued operations, net of income taxes” in the Consolidated Statement of Operations. In 2013, we completed the sale of the New England Media Group, consisting of The Boston Globe,  BostonGlobe.com, Boston.com, the Worcester Telegram & Gazette (“T&G”), Telegram.com and related properties. As  a result of the sale, the Company recorded a $49.1 million post-retirement curtailment gain in 2013, which is included  in the gain on sale within “(Loss)/income from discontinued operations, net of income taxes” in the Consolidated  Statement of Operations. This gain is primarily related to an acceleration of prior service credits from plan  amendments announced in prior years, and is due to a reduction in the expected years of future Company service for  employees at the New England Media Group.  In September 2014 and December 2014, the ERISA Management Committee approved certain changes to The  New York Times Company Retiree Medical Plan provisions, which triggered a remeasurement under ASC 715-60,  “Compensation — Retirement Benefits — Defined Benefit Plans — Other Postretirement.” The changes in the plan  provisions decreased obligations by $25.5 million and the change in discount rate as of the remeasurement date  increased obligations by $3.6 million. Overall, the remeasurement decreased our obligations by $21.9 million as  reflected in other comprehensive income in our Condensed Consolidated Balance Sheets and Condensed  Consolidated Statements of Comprehensive Income/(Loss). The changes in the benefit obligations recognized in other comprehensive loss were as follows: P. 88 – THE NEW YORK TIMES COMPANY (In thousands) December 28, 2014 December 29, 2013 December 30, 2012 Net actuarial loss/(gain) $ 8,882 $ (13,500) $ 11,562 Prior service credit (25,489) (1,690) GLYPH<151> Amortization of loss (4,948) (4,440) (3,328) Amortization of prior service credit 7,199 13,051 15,112 Recognition of prior service credit due to curtailment GLYPH<151> 49,122 27,213 Total recognized in other comprehensive (income)/loss (14,356) 42,543 50,559 Net periodic postretirement benefit expense/(income) 4,402 (52,543) (33,055) Total recognized in net periodic postretirement benefit income and other comprehensive (income)/loss $ (9,954) $ (10,000) $ 17,504 (In thousands) December 28, 2014 December 29, 2013 December 30, 2012 Service cost $ 580 $ 1,089 $ 957 Interest cost 3,722 4,101 4,985 Amortization and other costs 7,299 4,440 3,328 Amortization of prior service credit (7,199) (13,051) (15,112) Effect of curtailment GLYPH<151> (49,122) (27,213) Net periodic postretirement benefit expense/(income) $ 4,402 $ (52,543) $ (33,055)
