Additions to other long lived assets represent primarily equity method investments and long term refundable real estate taxes. 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, which may differ from amounts that would be incurred if such services were purchased separately by the business segment. Corporate assets are primarily cash and equivalents, deferred income tax benefits and refundable income taxes. 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 $21.3 million held by One Earth and NuGen will be used primarily to fund working capital needs for the subsidiaries.
