The stock exchange behind Facebook’s calamitous debut in 2012 has set aside tens of millions of dollars to compensate aggrieved investors. Nasdaq revealed yesterday that it had created a $31 million (GBP20.7 million) pool to settle class action litigation arising from Facebook’s $104 billion float. The social network’s debut in May 2012 was hampered by a series of technical issues with the Nasdaq platform. The exchange would later be fined $10 million by the US Securities and Exchange Commission (SEC) for “serious and pervasive violations of fundamental rules”.
