N-CSR, or the transition report or portion thereof, could not be filed within
the prescribed time period.

As reported in a press release dated December 13, 2005, First Bancorp (the
"Company") is in the process of preparing restated financial statements to
correct the accounting for certain mortgage-related transactions that the
subsidiary Bank entered into with other financial institutions and for the
interest rate swaps that it uses to hedge the interest rate risk inherent in its
brokered certificates of deposit and medium term notes. In addition, the
restatement may also address other accounting matters identified as a part of
the on-going restatement process. First BanCorp intends to complete the
restatement process and file restated financial statements with the Securities
and Exchange Commission in the summer of 2006. It expects to file the 2005
annual report on Form 10-K thereafter.


SEC   1344(07-03) Persons who are to respond to the collection of information
                  contained in this form are not required to respond unless
                  the form displays a currently valid OMB control number.

PART IV ---OTHER INFORMATION

      notification


                                               
Luis M. Cabrera                    (787)                     729-8111

(2)   Have all other periodic reports required under Section 13 or 15(d) of 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 file? If answer is
      no, identify report(s). Yes [ ] No [X]


      The Company's Quarterly Reports on Form 10-Q for the periods ended June
      30, 2005 and September 30, 2005 have not been filed, also pending
      completion of the Company's preparation of the restated financial
      statements.

(3)   Is it anticipated that any significant change in results of operations
      from the corresponding period for the last fiscal year will be reflected
      by the earnings statements to be included in the subject report or portion
      thereof?
                                                            Yes  [ ]    No   [X]

      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.

      The Company does not know now whether the results for the fiscal year
      ended December 31, 2005 will significantly differ from the 2004 fiscal
      year because it has not completed either the process of preparing restated
      financial statements for 2004 and for the first quarter of 2005 or the
      process of preparing interim financial statements for the second and third
      quarters of 2005.
