(“HAL”), causing HAL to become a qualified REIT subsidiary. As a result of the acquisition, we succeeded to HAL’s tax attributes, including HAL’s tax basis in its net assets. Prior to the acquisition, HAL was a corporation subject to federal and state income taxes. In connection with the acquisition of HAL, NHP acquired approximately $82.5 million of federal net operating losses (“NOLs”) which we can carry forward to future periods and the use of which is subject to annual limitations imposed by IRC Section 382. While we believe that these NOLs are accurate, any adjustments to HAL’s tax returns for periods prior to June 1, 2006 by the Internal Revenue Service could change the amount of the NOLs that we can utilize. We have used a portion of this amount in 2007 and 2008 and anticipate using additional amounts in future years. These NOLs are set to expire between 2017 and 2025. NOLs related to various states were also acquired and are set to expire based on the various laws of the specific states. </div> <div style="margin-top: 6pt; font-size: 1pt">  </div> <div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"> In addition, we may be subject to a corporate-level tax on any taxable disposition of HAL’s pre-acquisition assets that occurs within ten years after the June 1, 2006 acquisition. The corporate-level tax would be assessed only to the extent of the built-in gain that existed on the date of acquisition, based on the fair market value of the asset on June 1, 2006. We do not expect to dispose of any asset included in the HAL acquisition if such a disposition would result in the imposition of a material tax liability, and no such sales have taken place through December 31, 2010. Accordingly, we have not recorded a deferred tax liability associated with this corporate-level tax. Gains from asset dispositions occurring more than 10 years after the acquisition will not be subject to this corporate-level tax. However, we may dispose of HAL assets before the <font style="white-space: nowrap">10-year</font> period if we are able to complete a tax-deferred exchange. </div> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescription containing the entire income tax disclosure.
