Remarks

Index calculation: The PPVX is a weighted index so that the stocks of a few highly capitalized companies do not exert too much influence. It is divided into six classes, with different weighing points (WP) based on the companies' market capitalizations. A capitalization of less than €50 million has 1 WP; between €50 million and €200 million, 2 WP; between €200 million and €800 million, 3 WP (Canadian Solar, Centrotherm, Conergy, Delsolar, E-Ton, Gintech, Green Energy Technology, GT Solar, JA Solar, LDK Solar, Meyer Burger Technology, Neo Solar Power, NPC Inc., Q-Cells, ReneSola, Roth & Rau, Sino-American Silicon Products, Solarfun Power, Solargiga, STR Holdings, Woongjin Energy); between €800 million and €3.2 billion, 4 WP (Motech, Renewable Energy Corp., SolarWorld, SunPower, Suntech Power,Trina, Yingli); between €3.2 billion and €12.8 billion, 5 WP (First Solar and SMA Technology AG).
