The Company’s investments in equity affiliates are comprised principally of 50% ownership interests in a number of joint ventures that manufacture and sell coatings and glass products, the most significant of which produce fiber glass products and are located in Asia. The Company’s investments in and advances to equity affiliates also include its approximate 40% ownership interest in Pittsburgh Glass Works LLC (“PGW”), which had a carrying value of $94 million and $30 million at December 31, 2014 and December 31, 2013, respectively.

Until January 28, 2013, PPG held a 50% ownership interest in RS Cogen, LLC, which toll produced electricity and steam primarily for PPG's former Lake Charles, La. commodity chemicals facility and its joint venture partner under take-or-pay contracts with terms that extended to 2022. On January 28, 2013, PPG's investment in R.S. Cogen and its future purchase obligations under the take-or-pay commitments were transferred with the separation of its commodity chemicals business and the merger of the subsidiary holding the PPG commodity chemicals business with a subsidiary of Georgia Gulf. Refer to Note 2, "Acquisitions and Dispositions."

PPG’s share of undistributed net earnings of equity affiliates was $171 million and $98 million as of December 31, 2014 and December 31, 2013, respectively. Dividends received from equity affiliates were $5 million, $9 million and $12 million in 2014, 2013 and 2012, respectively.
