The Company’s liquidity is concentrated in trade receivables that arise from sales of TiO₂ and titanium feedstock to customers in the TiO2 industry. The industry concentration has the potential to impact the Company’s overall exposure to credit risk, either positively or negatively, in that its customers may be similarly affected by changes in economic, industry or other conditions. The Company performs ongoing credit evaluations of its customers, and uses credit risk insurance policies from time to time, as deemed appropriate, to mitigate credit risk, but generally does not require collateral. The Company maintains allowances for potential credit losses based on historical experience. For the year ended December 31, 2012, the Company’s ten largest TiO2 customers represented approximately 46% of its total TiO₂ net sales; however, no single customer accounted for more than 10% of total net sales.
