## 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. According to Vigeo, its indices are composed of the highest-ranking listed companies evaluated in terms of performance in
