Crocs indicates that its sales exceeded $1 billion in 2011 for the first time in its history, as it revenues ended up at the high end of its expectations in the fourth quarter of the financial year. Investors responded positively, boosting the company's value on the stock exchange by 4.6 percent. The good results were given by Crocs' management at the ICR Xchange investor conference a few days ago. Two-thirds of the recent growth has come from higher-selling prices, thanks to the introduction of new products, but clogs still represent about half of the total business. The management is predicting annual growth of 10 to 15 percent for the next three years. While wholesale will continue to represent two-thirds of the total turnover, Crocs has just announced the appointment of a European retail director, Ann Chan, who previously worked for La Senza.
