     the Securities Exchange Act of 1934 or section 30 of the Investment
     Company Act of 1940 during the preceding 12 months or for such shorter
     period that the registrant was required to file such report(s) been

                                       [X]  Yes              [  ]  No

If so: attach an explanation of the anticipated change, both narratively and
quantitatively, and, if appropriate, state the reasons why a reasonable
estimate of the results cannot be made.


Currently, the floor of our building (a SMART Building) is under 
construction.  We believe the construction may have caused our modem line 
to be turned off which made it impossible to file our 10-Q in a timely 
manner.  We anticipate the filing of the 10-Q to follow this form 12B-25.
