The Company believes that the per unit performance information is calculated and presented in accordance with the guidelines set forth under SFAS 128. The calculation includes the components of the results of operations divided by the weighted average number of units outstanding for the relevant period.
However, in future filings, beginning with Grant Park’s quarterly report on Form 10-Q for the quarter ended March 31, 2006, the increase or decrease in the net asset value per unit, per class, will also be included in the financial statements in the Statements of Operations.
In connection with this response letter, please be advised that Grant Park acknowledges that:
| (1) | Grant Park is responsible for the adequacy and accuracy of the disclosure in its filings; |
| (2) | Staff comments or changes to disclosure in response to staff comments do not foreclose the Commission from taking any action with respect to the filings; and |
| (3) | Grant Park may not assert staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States. |
We appreciate your prompt review of and assistance with this response. Please feel free to call me at 312-609-7835 if you have any questions or further comments.
