Dear Ms. Mengiste:

This letter responds to your additional comment received by telephone on April
1, 2009 for the N-14 filings referenced above. The comment and response are
outlined below:

     COMMENT: Confirm that the applicable Buying Fund and Selling Fund share
     classes exist for each proposed Reorganization.

     RESPONSE: The applicable share classes exist for each Buying Fund and
     Selling Fund involved in the proposed Reorganizations. For your reference
     we have provided a chart, attached as Exhibit A to this letter, which
     outlines the corresponding Buying Fund and Selling Fund series and class
     identifiers. With regard to



                                                                    Page 2 of 11


     certain Seligman Funds, share classes currently identified as Class R and
     Class I will be redesignated as Class R2 and Class R5, respectively, as a
     part of the integration-related work. These changes will occur after the
     effectiveness of the Form N-14 Registration Statements but prior to the
     Reorganization transactions and have been appropriately noted in Part A and
     Part B of the Form N-14 Registration Statements.

In connection with the above-referenced Registration Statements, each Registrant
hereby acknowledges the following:

     The disclosures in the filing are the responsibility of the Registrant and
     the Registrant is fully responsible for the adequacy or accuracy of the
     disclosures in this filing. The Registrant represents to the Commission
     that comments made by the Commission, or the staff acting pursuant to
     delegated authority, or changes to disclosure in response to staff comments
     in the filing reviewed by the staff, do not foreclose the Commission from
     taking any action with respect to the filing, and the Registrant represents
     that it will not assert this action as a defense in any proceeding
     initiated by the Commission or any person, under the federal securities
     laws of the United States.
