File Nos. 33-33980 and 811-6067
Dear Ms. Hatch:
I am writing on behalf of the above-referenced Registrant, pursuant to Rule
477(a) under the Securities Act of 1933, as amended, to request the consent of
the U.S. Securities and Exchange Commission (the "Commission") to the withdrawal
of the post-effective amendment to the Registrant's registration statement on
Form N-1A filed with EDGAR submission type 485BPOS, which was accepted via the
EDGAR system at 4:17 p.m. on September 28, 2007 (Accession No.
0001193125-07-210001). Such post-effective amendment was filed with the
incorrect EDGAR submission type of 485BPOS. The post-effective amendment has
been re-filed using the correct EDGAR submission type of 485BXT.
Therefore, Registrant respectfully requests the Commission's consent to the
withdrawal of Registrant's post-effective amendment (Accession No.
0001193125-07-210001) filed under the EDGAR submission type 485BPOS.
If you have any questions, or require anything further regarding the
request, please contact me at (215) 564-8048.
Very truly yours,
/s/Jana L. Cresswell
