PART III — NARRATIVE

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

SuccessFactors, Inc. (“SuccessFactors” or “the Company”) is unable to timely file its Annual Report on Form 10-K for the year ended December 31, 2010 (the “Form 10-K”) without unreasonable effort or expense by the prescribed due date. The Company reassessed its accounting for an Australian holding company, originally established to effect the third quarter acquisition of Infohrm Pty. Ltd (Inform), and concluded that the Company had not correctly accounted for a $3.5 million foreign exchange gain on an intercompany loan in the Australian holding company. As a result, the Company expects to file an amended Form 10-Q for the third quarter of fiscal 2010. The Company expects the line item “interest income and other, net” to decrease and the line item “net loss,” on a generally accepted accounting principles (GAAP) basis, to increase by approximately $3.5 million for the three and nine months ended September 30, 2010 and such line items to decrease and increase, respectively, by up to approximately $1.5 million for the three months ended December 31, 2010 and approximately $5.0 million for the year ended December 31, 2010.

The changes had no impact on previously-reported total cash flows from operations, revenues, billings, non-GAAP operating results and non-GAAP net loss (which excludes the foreign exchange gain on the intercompany loan).

SuccessFactors currently anticipates that the Form 10-K will be filed on or before the fifteenth calendar day following the prescribed due date.

(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 quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.
