NEW YORK, Nov. 20, 2014 /PRNewswire/ -- S&P Dow Jones Indices will make the following changes to the S&P MidCap 400 and S&P SmallCap 600 indices:

• Western Refining Inc. (NYSE: WNR) will replace Bally Technologies Inc. (NYSE:BYI) in the S&P MidCap 400 after the close of trading on Monday, November 24. S&P SmallCap 600 constituent Scientific Games Corp. (NASD:SGMS) is acquiring Bally Technologies in a transaction expected to be completed on November 21.
• California Resources Corp. (NYSE:CRCwi) will replace Rayonier Advanced Materials Inc. (NYSE:RYAM) in the S&P MidCap 400, and Rayonier Advanced Materials will replace Symmetry Medical Inc. (NYSE:SMA) in the S&P SmallCap 600 after the close of trading on Friday, November 28. S&P 100 & 500 constituent Occidental Petroleum Inc. (NYSE:OXY) is spinning off California Resources in a transaction expected to be completed on that date. Occidental Petroleum will remain in the S&P 100 & 500 following the distribution. Rayonier Advanced Materials' market capitalization is below $1.1 billion, making it more representative of the small cap market space. Symmetry Medical is selling certain assets that will result in the remaining company's market capitalization being too small for continued inclusion in the SmallCap 600.

Western Refining operates as an independent crude oil refiner and marketer of refined products. Headquartered in El Paso, TX, the company will be added to the S&P MidCap 400 GICS (Global Industry Classification Standard) Oil & Gas Refining & Marketing Sub-Industry index.

California Resources provides oil and natural gas exploration and production services. Headquartered in Los Angeles, CA, the company will be added to the S&P MidCap 400 GICS Oil & Gas Exploration & Production Sub-Industry index.

Rayonier Advanced Materials is a producer of high-purity cellulose. Headquartered in Jacksonville, FL, the company will be added to the S&P SmallCap 600 GICS Specialty Chemicals Sub-Industry index.
