Core Added to OSX and Vigeo Indices Core Laboratories celebrated many memorable events in 2013, including its 18th  year as a publicly traded Company and our 15th year of being listed on the New York  Stock Exchange (NYSE). Core also accomplished an ultra-long-term goal of being  nominated to the Philadelphia Oil Services Sector Index, better known on the floor  of the NYSE simply as the OSX. On 26 November 2013, Core Laboratories was added to the OSX, which is  composed of fifteen of the leading oilfield service companies, including Schlumberger,  Halliburton, Baker Hughes, National Oilwell Varco, Oceaneering, Tidewater, and Oil  States International, among others. The Index is designed to track the performance  of a representative group of companies involved in the oilfield services sector. When Core was added to the index, the OSX was at 278.84 and the CLB share  price was $185.37. The Index was established on 31 December 1996 with a base  of 75.00, on which day the CLB share price was $3.93. The Index is price-weighted;  therefore, CLB has the greatest weighting of the fifteen companies, representing  about 20% of the entire index. Since its inception, the OSX share price has increased  almost four-fold, while CLB shares are up over 45-fold. Table 6 shows the 15 members of the OSX and how each company’s respective  shares traded in 2013. Core Laboratories led the other 14 companies with a total  shareholder return (TSR) of 76.3%.  Other notables were Halliburton with  a 48.0% TSR and Schlumberger, which  registered a TSR of 32.1%.  The Company’s listing on the NYSE  Euronext Exchange in Amsterdam is  also yielding benefits. In December  2013, Core Lab was added to two NYSE  Euronext Indices – the Euronext Vigeo  US 50 and the Euronext Vigeo World  120. Vigeo describes the latter index  as containing “the 120 most advanced  companies at the global level”. Vigeo is  one of the leading providers of Socially  Responsible Investment analysis of  public companies, having reviewed over  2,500 companies worldwide.
