RULE 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate.)


  (a)   The reasons described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;
  (b)   The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and
  (c)   The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.




State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, N-SAR, N-CSR or the transition report or portion thereof, could not be filed within the prescribed time period.

As previously announced and as described in the Current Report on Form 8-K of Transaction Systems Architects, Inc. (the “Company”) dated October 27, 2006, the Company’s Audit Committee initiated a voluntary review of the Company’s historical stock option grants for all periods from 1995 to present. The Audit Committee was assisted by independent counsel and outside accounting experts in this review. The Company determined that measurement dates for accounting purposes differed from recorded dates for a number of awards beginning with the Company’s initial public offering in 1995 through fiscal year 2002. Under accounting principles in effect during this period, some of these differences required that non-cash charges be recorded to the extent that TSA’s stock price on the measurement dates were higher than the prices on the recorded dates. On October 27, 2006, the Board of Directors concluded that the Company’s financial statements and all earnings releases and similar communications issued by the Company relating to financial periods since fiscal year 1995 should no longer be relied upon. As described in the Current Report on Form 8-K of Company dated March 16, 2007, the Company announced the completion of its voluntary review of the Company’s historical stock option granting practices and the resulting estimated non-cash stock based compensation-related adjustments to prior period financial statements. The Company has completed its analysis of the accounting treatment for certain past stock option grants to determine the extent of corrections that were required to its previously reported financial results. These corrections are contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2006, which was filed on May 11, 2007.

As a result of the delay in completing the fiscal 2006 year-end audit and the resulting delay in Company’s ability to file its 10-Q for the first fiscal quarter of fiscal 2007, the Company was not able to file its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2007 on the May 10, 2007 required filing date. The Company intends to continue to devote all available resources with the objective of filing its Form 10-Q for such period as promptly as practicable.

(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 filed?

Quarterly Report on Form 10-Q for the quarter ended December 31, 2006.

Current Report on Form 8-K/A, which would have amended the Current Report on Form 8-K dated October 2, 2006 to include the financial information required by Form 8-K in connection with the September 29, 2006 acquisition by the Company of P&H Solutions, Inc.

(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     x  No

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

No significant change in the results of operations from the fiscal 2006 period will be reflected in the Company’s second fiscal quarter of fiscal 2007 Form 10-Q, other than as related to the Company’s historical stock option practices during prior fiscal periods discovered during the Audit Committee review.
