[1] Impairment losses will not be recognized until the related properties are sold and realization is dependent upon generating sufficient taxable income in the year the property is sold.

[2] We have net operating loss carryforwards of $31.5 million that expire between the years of 2029 and 2034.

[3] Management believes it is more likely than not that a portion of the deferred tax assets, which primarily consists of impairment losses, interest expense and net operating losses, will not be realized and established a valuation allowance. However, the amount of the deferred tax asset considered realizable could be reduced if estimates of future taxable income are reduced.
