13.	Income Taxes

For federal income tax purposes, as well as for state income tax purposes in the majority of the states in which the Partnership operates, the earnings attributable to the Partnership, as a separate legal entity, and the Operating Partnership are not subject to income tax at the Partnership level. Rather, the taxable income or loss attributable to the Partnership, as a separate legal entity, and to the Operating Partnership, which may vary substantially from the income before income taxes, reported by the Partnership in the condensed consolidated statement of operations, are includable in the federal and state income tax returns of the individual partners. The aggregate difference in the basis of the Partnership's net assets for financial and tax reporting purposes cannot be readily determined as the Partnership does not have access to information regarding each partner's basis in the Partnership.

The earnings of the Partnership's Corporate Entities are subject to federal and state income taxes. However, the Corporate Entities have experienced operating losses in recent years, and therefore a full valuation allowance has been provided against the deferred tax assets. As a result, at present, many of those Corporate Entities do not report a tax provision. The conclusion that a full valuation allowance is necessary was based upon an analysis of all available evidence, both negative and positive at the balance sheet date, which, taken as a whole, indicates that it is more likely than not that sufficient future taxable income will not be available to utilize the deferred tax assets of the Corporate Entities. Management's periodic reviews include, among other things, the nature and amount of the taxable income, the expected timing of when assets will be used or liabilities will be required to be reported and the reliability of historical profitability of businesses expected to provide future earnings. Furthermore, management considered tax-planning strategies it could use to increase the likelihood that the deferred tax assets will be realized.

In prior business combinations, the Partnership acquired (or established in purchasing accounting, as applicable) deferred tax assets. Certain provisions of the accounting guidance concerning business combinations, in particular a provision related to the accounting for acquired tax benefits, are required to be applied regardless of when the business combination occurred. Therefore, to the extent the Partnership's Corporate Entities generate taxable profits that enable the utilization of tax benefits acquired in prior business combinations, the corresponding reduction in the valuation allowance will be recorded as a reduction in the provision for income taxes. This reduction in tax expense would generally be offset either currently or over time, by an increase in tax expense associated with the taxable income that enabled utilization of the deferred tax asset.
