The  aggregate amount of other long-term debt maturing during the next five years is approximately: $0.2 million in each of 2001 and  2002  $0.1 million in each of 2003  2004 and 2005  and  $0.4 million thereafter. The income tax provision in the accompanying Consolidated Statements of Operations for the years ended December 31  2000  1999 and 1998 consisted of the following (in thousands): EMCOR adopted Fresh-Start Accounting in connection with EMCOR’s reorganization in December 1994. As a result  the tax benefit of any net operating loss carryforwards or net deductible temporary differences which existed as of December 15  1994 will result in a charge to the tax provision (provision in lieu of income taxes) and to capital surplus. Amounts credited to capital surplus were $24.4 million  $15.6 million and $8.2 million for the years ended December 31  2000  1999 and 1998  respectively. EMCOR files a consolidated federal income tax return including  all of its U.S. subsidiaries. At December 31  2000  EMCOR had net operating loss carryforwards (“NOLs”) for U.S. income tax  purposes of approximately $40.0 million  which expire in the years 2009 through 2012. The NOLs are subject to review by the Internal Revenue Service. Future changes in ownership of EMCOR  as defined by Section 382 of the Internal Revenue Code  could limit the amount of NOLs available for use in any one year. In the United Kingdom  EMCOR’s wholly owned subsidiary  Drake & Scull  has a trading loss carry-forward of approximately  $6.0 million. Trading losses may be carried forward  without a  time limit  against future income from the same trade.
