Commitments and Contingencies Disclosure [Abstract] |
COMMITMENTS AND CONTINGENCIES | COMMITMENTS AND CONTINGENCIES The following table summarizes our contractual commitments under non-cancelable operating leases and purchase contracts as of December 31, 2013:

Total commitments | $ | 237.0 |  |  | $ | 103.3 |
Our operating lease commitments are primarily for railroad cars but also include distribution, warehousing and office space and data processing and office equipment. Virtually none of our lease agreements contain escalation clauses or step rent provisions. Total rent expense charged to operations amounted to $64.2 million, $60.5 million and $53.8 million in 2013, 2012 and 2011, respectively (sublease income is not significant). The above purchase commitments include raw material, capital expenditure and utility purchasing commitments utilized in our normal course of business for our projected needs. In conjunction with the St. Gabriel, LA conversion and expansion project, which was completed in the fourth quarter of 2009, we entered into a twenty-year brine and pipeline supply agreement with PetroLogistics. PetroLogistics installed, owns and operates, at its own expense, a pipeline supplying brine to the St. Gabriel, LA facility. Beginning November 2009, we are obligated to make a fixed annual payment over the life of the contract of $2.0 million for use of the pipeline, regardless of the amount of brine purchased. We also have a minimum usage requirement for brine of $8.4 million over the first five-year period of the contract. We have met or exceeded the minimum brine usage requirements since the inception of the contract. After the first five-year period, the contract contains a buy out provision exercisable by us for $12.0 million. We, and our subsidiaries, are defendants in various legal actions (including proceedings based on alleged exposures to asbestos) incidental to our past and current business activities. At December 31, 2013 and 2012, our consolidated balance sheets included liabilities for these legal actions of $19.3 million and $15.2 million, respectively. These liabilities do not include costs associated with legal representation. Based on our analysis, and considering the inherent uncertainties associated with litigation, we do not believe that it is reasonably possible that these legal actions will materially adversely affect our financial position, cash flows or results of operations. During the ordinary course of our business, contingencies arise resulting from an existing condition, situation or set of circumstances involving an uncertainty as to the realization of a possible gain contingency. In certain instances such as environmental projects, we are responsible for managing the cleanup and remediation of an environmental site. There exists the possibility of recovering a portion of these costs from other parties. We account for gain contingencies in accordance with the provisions of ASC 450 and therefore do not record gain contingencies and recognize income until it is earned and realizable. For the year ended December 31, 2013, we recognized $11.0 million as a reduction of cost of goods sold related to a Chlor Alkali Products favorable contract settlement. Also for the year ended December 31, 2013, we recognized $13.9 million as a reduction of selling and administration expense related to the recovery of legacy legal costs.
