 Item 3. Quantitative and Qualitative Disclosures About Market Risk.
  
 Item 4. Controls and Procedures
 (a)
    
    Evaluation of disclosure controls and procedures:
 As of the end of the period covered by this quarterly report, we carried out an
evaluation, under the supervision and with the participation of the Companys management,
including the Companys Chief Executive Officer and Chief Financial Officer, of the
effectiveness of the design and operation of the Companys disclosure controls and
procedures. Based upon that evaluation, the Chief Executive Officer and Chief
Financial Officer concluded that the Companys disclosure controls and procedures
are effective in timely alerting them to material information relating to the Company
required to be included in the Companys periodic Securities and Exchange Commission
filings.
 (b)
    
    Changes in internal controls:
 There were no significant changes in the Companys internal controls over financial
reporting that occurred during our most recent fiscal quarter that materially affected,
or is reasonably likely to materially affect, our internal control over financial
reporting.
 (c)
    
    Asset-Backed issuers:
 Not applicable.
