The following table summarizes segment and other results and assets (amounts in thousands):

Certain corporate costs and expenses, including information technology, employee benefits and other shared services are allocated to the business segments. The allocations are generally amounts agreed upon by management and are based on a reasonable and systematic approach, which may differ from amounts that would be incurred if such services were purchased separately by the business segment. Corporate assets are primarily cash. Cash, except for cash held by One Earth and NuGen, is considered to be fungible and available for both corporate and segment use depending on liquidity requirements. Cash of approximately $115.8 million held by One Earth and NuGen will be used by the subsidiaries primarily to fund liquidity requirements, maintain adequate working capital levels and pay dividends.
