Condensed Consolidated Financial Statements

Condensed Consolidated Financial Statements

1. Condensed Consolidated Financial Statements

The unaudited condensed consolidated financial statements include the accounts of ACI Worldwide, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of September 30, 2011, and for the three and nine months ended September 30, 2011 and 2010, are unaudited and reflect all adjustments of a normal recurring nature, except as otherwise disclosed herein, which are, in the opinion of management, necessary for a fair presentation, in all material respects, of the financial position and operating results for the interim periods. The condensed consolidated balance sheet as of December 31, 2010 is derived from the audited financial statements.

The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2010, filed on February 18, 2011. Results for the three and nine months ended September 30, 2011, are not necessarily indicative of results that may be attained in the future.

The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue

Update to Revenue Accounting Policies. With the exception of the adoption of the new accounting pronouncements related to revenue recognition, which are discussed below, there have been no material changes to the Company’s significant accounting policies, as compared to the significant accounting policies described in its annual report on Form 10-K for the fiscal year ended December 31, 2010.

Revenue Recognition for Arrangements with Multiple Deliverables.

Effective January 1, 2011, the Company adopted on a prospective basis for all new or materially modified arrangements entered into on or after that date, the amended accounting guidance for multiple-deliverable revenue arrangements and the amended guidance related to the scope of existing software revenue recognition guidance. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements for the three and nine months ended September 30, 2011, nor does the Company expect it to have a material impact on its future financial statements.

A multiple-deliverable arrangement is separated into more than one unit of accounting if the delivered item(s) has value to the customer on a stand-alone basis; if the arrangement includes a general right of return relative to the delivered item(s); and if delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. If these criteria are not met, the arrangement is accounted for as a single unit of accounting which would result in revenue being recognized ratably over the contract term or being deferred until the earlier of when such criteria are met or when the last undelivered element is delivered. If these criteria are met for each, the arrangement consideration is allocated to the separate units of accounting based on each unit’s relative selling price. The selling price for each element is based upon the following selling price hierarchy: vendor-specific objective evidence (“VSOE”) if available, third party evidence (“TPE”) if VSOE is not available, or estimated selling price if neither VSOE nor TPE is available.

The Company enters into hosting-related arrangements that may consist of multiple service deliverables including initial implementation and setup services; on-going support services; and other services. The Company’s hosted products operate in a highly regulated and controlled environment which requires a highly specialized and unique set of initial implementation and setup services prior to the commencement of hosting-related services. Due to the essential and specialized nature of the implementation and setup services, these services do not qualify as separate units of accounting separate from the hosting service as the delivered services do not have value to the customer on a stand-alone basis. The on-going support and other services are considered as separate units of accounting. The total arrangement consideration is allocated to each of the separate units of accounting based on their relative selling price and revenue is recognized over their respective service periods. As the support and other services periods are the same as the hosting service period, the recognition pattern is similar to what was experienced prior to adopting the amended accounting guidance for multiple-deliverable revenue arrangements.

Vendor-Specific Objective Evidence

Certain of the Company’s software license arrangements include post contract customer support (maintenance or “PCS”) terms that fail to achieve VSOE of fair value due to non-substantive renewal periods, or contain a range of possible PCS renewal amounts. As a result of the maturation of certain retail payment engine products, including BASE24, a higher number of software license arrangements fail to achieve VSOE of fair value for PCS due to non-substantive renewal periods, or contain a range of possible PCS renewal amounts. For these arrangements, VSOE of fair value of PCS does not exist and revenues for the software license, PCS and services, if applicable, are considered to be one accounting unit and are therefore recognized ratably over the longer of the contractual service term or the initial PCS term once the delivery of both services has commenced. The Company typically classifies revenues associated with these arrangements in accordance with the contractually specified amounts, which approximate fair value assigned to the various elements, including software license fees, maintenance fees and services, if applicable.

This allocation methodology has been applied to the following amounts included in revenues in the consolidated statements of operations from arrangements for which VSOE of fair value does not exist for each undelivered element (in thousands):

		September 30,		September 30,		September 30,		September 30,
	Three Months Ended September 30,				Nine Months Ended September 30,
	2011		2010		2011		2010
Software license fees	$	11,954	$	14,553	$	53,794	$	26,335
Maintenance fees		3,047		2,349		11,859		5,507
Services		447		1,216		906		4,024

Total	$	15,448	$	18,118	$	66,559	$	35,866

2. Acquisitions

ISD Holdings, Inc.

On March 18, 2011, the Company closed the acquisition of ISD Holdings, Inc. and its 100% owned subsidiary ISD Corporation (collectively “ISD”). ISD’s suite of products enables retailers to consolidate, manage, secure and route all electronic transactions from their point-of-sale systems to third-party processors for authorization and settlement.

The aggregate purchase price of ISD was $19.2 million, after working capital adjustments in accordance with the terms of the purchase agreement, which included cash acquired of $2.4 million. The allocation of the purchase price to specific assets and liabilities was based on the relative fair value of all assets and liabilities.

In connection with the acquisition, the Company recorded the following amounts based upon its preliminary purchase price allocation during the nine months ended September 30, 2011 (in thousands, except weighted-average useful lives):

		September 30,			September 30,
	Amount			Weighted- Average Useful Lives
Cash	$	2,375
Accounts Receivable		2,030
Other current assets		958

Total current assets acquired		5,363


Noncurrent assets:
Property and equipment		519
Goodwill		11,380
Intellectual property rights		2,338			5 years
Customer relationships		4,059			9 years
Trade name		247			5 years

Total assets acquired		23,906


Current liabilities acquired		(4,681	)


Net assets acquired	$	19,225

Factors contributing to the purchase price that resulted in the goodwill (which is not tax deductible) include the acquisition of management, sales, and technology personnel with the skills to market new and existing products of the Company. Pro forma results are not presented because they are not material.

- Definition

Debt

9 Months Ended

Sep. 30, 2011

Debt

3. Debt

Credit Facility

The Company’s revolving credit facility expired and was repaid in full on September 29, 2011. On September 29, 2011, the Company entered into a five year senior secured revolving credit facility (the “Facility”) with Wells Fargo Bank, National Association (“Wells Fargo”), as lender, providing for revolving loans, swingline loans and letters of credit in an aggregate principal amount not to exceed $100 million. Subject to certain conditions the Company has the right to request an increase in the aggregate principal amount of the revolving credit facility or optional incremental term loans. The Facility has a maturity date of September 29, 2016, at which time any principal amounts outstanding are due. Obligations under the Facility are secured and are jointly and severally guaranteed by certain domestic and foreign subsidiaries of the Company.

The Company may select either a base rate loan or a LIBOR based loan. Base rate loans are computed at the highest of (a) the national prime interest rate as announced by Wells Fargo, (b) the sum of the Federal fund rate plus 0.5%, or (c) the LIBOR rate for an interest period of one month plus 1.0%, in each case, plus a margin ranging from 0.50% to 1.25%. LIBOR based loans are computed at the applicable LIBOR rate plus a margin ranging from 1.50% to 2.25%. The margins are dependent upon the Company’s total leverage ratio at the end of each quarter. The initial borrowing rate on September 29, 2011 was set using the LIBOR rate option, effecting a rate of 1.74%. Interest is due and payable quarterly.

The interest rate in effect at September 30, 2011 was 1.74%. There is also an unused commitment fee to be paid quarterly of 0.25% to 0.40% based on the Company’s leverage ratio. The initial principal borrowings of $75 million were outstanding at September 30, 2011. The amount of unused borrowings actually available under the Facility varies in accordance with the terms of the agreement.

The Facility contains certain affirmative and negative covenants, including limitations on the incurrence of indebtedness, asset dispositions, acquisitions, investments, dividends and other restricted payments, liens and transactions with affiliates. The Facility also contains financial covenants relating to maximum permitted leverage ratio and the minimum fixed charge coverage ratio. At September 30, 2011, (and at all times during the period) the Company was in compliance with its debt covenants. The Facility does not contain any subjective acceleration features and does not have any required payment or principal reduction schedule and is included as long-term in the accompanying consolidated balance sheet.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Stock-Based Compensation Plans

9 Months Ended

Stock-Based Compensation Plans

4. Stock-Based Compensation Plans

Employee Stock Purchase Plan

Under the Company’s 1999 Employee Stock Purchase Plan, as amended (the “ESPP”), a total of 1,500,000 shares of the Company’s common stock have been reserved for issuance to eligible employees. Participating employees are permitted to designate up to the lesser of $25,000 or 10% of their annual base compensation for the purchase of common stock under the ESPP. Purchases under the ESPP are made one calendar month after the end of each fiscal quarter. The price for shares of common stock purchased under the ESPP is 85% of the stock’s fair market value on the last business day of the three-month participation period. Shares issued under the ESPP during the nine months ended September 30, 2011 and 2010 totaled 30,021 and 45,642, respectively.

Stock-Based Payments

A summary of stock options issued pursuant to the Company’s stock incentive plans is as follows:

		September 30,			September 30,		September 30,		September 30,
	Number of Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value of In-the-Money Options
Outstanding as of December 31, 2010		3,510,538		$	21.55
Granted		70,000			29.00
Exercised		(232,499	)		11.95
Forfeited		(22,351	)		20.19

Outstanding as of September 30, 2011		3,325,688		$	22.38		5.14	$	21,022,107


Exercisable as of September 30, 2011		2,267,032		$	22.40		4.55	$	15,405,992

As of September 30, 2011, the Company expects that 94.9% of the options will vest over the vesting period.

The weighted-average grant date fair value of stock options granted during the nine months ended September 30, 2011 and 2010 was $13.69 and $9.39, respectively. The Company issued treasury shares for the exercise of stock options during the nine months ended September 30, 2011 and 2010. The total intrinsic value of stock options exercised during the nine months ended September 30, 2011 and 2010 was $4.5 million and $1.2 million, respectively.

There were no options granted during the three months ended September 30, 2011. The fair value of options granted during the nine months ended September 30, 2011 and 2010 was estimated on the date of grant using the Black-Scholes option-pricing model, a pricing model acceptable under U.S. GAAP, with the following weighted-average assumptions:

		September 30,			September 30,
	Nine Months Ended			Nine Months Ended
	September 30, 2011			September 30, 2010
Expected life (years)		5.50			5.63
Interest rate		1.6	%		2.3	%
Volatility		50.8	%		51.7	%
Dividend yield		—			—

Expected volatilities are based on the Company’s historical common stock volatility derived from historical stock price data for historical periods commensurate with the options’ expected life. The expected life of options granted represents the period of time that options granted are expected to be outstanding. The Company used the simplified method for determining the expected life. The simplified method was used as the historical data did not provide a reasonable basis upon which to estimate the expected term due to the extended period during which individuals were unable to exercise options while the Company was not current with its filings with the Securities and Exchange Commission (“SEC”). The risk-free interest rate is based on the implied yield currently available on United States Treasury zero coupon issues with a term equal to the expected term at the date of grant of the options. The expected dividend yield is zero as the Company has historically paid no dividends and does not anticipate dividends to be paid in the future.

A summary of nonvested long-term incentive program performance share awards (“LTIP performance shares”) outstanding as of September 30, 2011 and changes during the period are as follows:

		September 30,			September 30,
Nonvested LTIP Performance Shares	Number of Shares at Expected Attainment			Weighted- Average Grant Date Fair Value
Nonvested as of December 31, 2010		499,035		$	20.57
Forfeited		(27,274	)		18.69

Nonvested as of September 30, 2011		471,761		$	20.72

A summary of nonvested restricted share awards (“RSAs”) as of September 30, 2011 and changes during the period are as follows:

		September 30,			September 30,
Nonvested Restricted Share Awards	Number of Restricted Share Awards			Weighted-Average Grant Date Fair Value
Nonvested as of December 31, 2010		192,298		$	18.42
Awarded		1,300			29.00
Vested		(79,550	)		18.06
Forfeited		(9,000	)		17.36

Nonvested as of September 30, 2011		105,048		$	18.92

During the nine months ended September 30, 2011, 79,550 of the RSAs vested. The Company withheld 23,370 of those shares to pay the employees’ portion of the minimum payroll withholding taxes.

As of September 30, 2011, there were unrecognized compensation costs of $4.5 million related to nonvested stock options, $1.3 million related to the nonvested RSAs, and $5.1 million related to the LTIP performance shares, which the Company expects to recognize over weighted-average periods of 1.6 years, 1.3 years and 1.9 years, respectively.

The Company recorded stock-based compensation expenses for the three months ended September 30, 2011 and 2010 related to stock options, LTIP performance shares, RSAs, and the ESPP of $2.2 million and $1.9 million, respectively, with corresponding tax benefits of $0.7 million and $0.7 million, respectively. The Company recorded stock-based compensation expenses for the nine months ended September 30, 2011 and 2010 related to stock options, LTIP performance shares, RSAs, and the ESPP of $6.7 million and $5.5 million, respectively, with corresponding tax benefits of $2.4 million and $2.0 million, respectively. Tax benefits in excess of the option’s grant date fair value are classified as financing cash flows. No stock-based compensation costs were capitalized during the nine months ended September 30, 2011 and 2010. Estimated forfeiture rates, stratified by employee classification, have been included as part of the Company’s calculations of compensation costs. The Company recognizes compensation costs for stock option awards that vest with the passage of time with only service conditions on a straight-line basis over the requisite service period.

Cash received from option exercises for the nine months ended September 30, 2011 and 2010 was $2.8 million and $2.5 million, respectively. The actual tax benefit realized for the tax deductions from option exercises totaled $1.6 million and $0.4 million for the nine months ended September 30, 2011 and 2010, respectively.

Fair Value of Financial Instruments

9 Months Ended

Sep. 30, 2011

Fair Value of Financial Instruments

8. Fair Value of Financial Instruments

ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements.

ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. ASC 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

— Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

— Level 2 Inputs—Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

— Level 3 Inputs—Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

Available-for-Sales Securities. Equity securities are reported at fair value utilizing Level 1 inputs. The Company’s equity securities are comprised entirely of S1 Corporation common stock. The Company utilizes quoted prices from an active exchange market to fair value its equity securities.

The equity securities are accounted for as available-for-sale securities and are included in other noncurrent assets in the accompanying condensed consolidated balance sheets.

The Company looks at its classifications within the fair value hierarchy at each reporting period. There were no transfers between any levels of the fair value hierarchy during the periods presented in the table below.

The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (in thousands):

		September 30,		September 30,		September 30,
	Fair Value Measurements at Reporting Date Using
Description	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Equity Securities	$	10,151	$	—	$	—

Total assets as of September 30, 2011	$	10,151	$	—	$	—

Equity Securities	$	—	$	—	$	—

Total assets as of December 31, 2010	$	—	$	—	$	—

The Company pays interest quarterly on its revolving credit facility based upon the LIBOR rate plus a margin ranging from 0.50% to 1.25%, the margin being dependent upon the Company’s total leverage ratio at the end of the quarter. At September 30, 2011, the fair value of the Company’s revolving credit facility approximates its carrying value.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Basic earnings per share is computed on the basis of weighted average outstanding common shares. Diluted earnings per share is computed on the basis of basic weighted average outstanding common shares adjusted for the dilutive effect of stock options and other outstanding dilutive securities.

The following table reconciles the average share amounts used to compute both basic and diluted loss per share (in thousands):

		September 30,		September 30,		September 30,		September 30,
	Three Months Ended September 30,				Nine Months Ended September 30,
	2011		2010		2011		2010

Diluted weighted average shares outstanding		34,305		33,480		34,182		33,907

For the three and nine months ended September 30, 2011, 3.2 million options to purchase shares, restricted share awards, common stock warrants and contingently issuable shares were excluded from the diluted earnings per share computation as their effect would be anti-dilutive. For the three and nine months ended September 30, 2010, 5.5 million options to purchase shares, restricted share awards, common stock warrants and contingently issuable shares were excluded from the diluted earnings per share computation as their effect would be anti-dilutive.

Of the $15.9 million accumulated other comprehensive loss included in the Company’s consolidated balance sheets $16.1 million represents the accumulated foreign currency translation adjustment. Since the undistributed earnings of the Company’s foreign subsidiaries are considered to be permanently reinvested, the components of accumulated other comprehensive income (loss) have not been tax effected. The accumulated other comprehensive loss is partially offset by the $0.2 million unrealized gain on available-for-sale securities.

- Definition

The entire disclosure for comprehensive income. Includes, but is not limited to, the following: 1) the amount of income tax expense or benefit allocated to each component of other comprehensive income, including reclassification adjustments, 2) the reclassification adjustments for each classification of other comprehensive income and 3) the ending accumulated balances for each component of comprehensive income.

Income Taxes

Income Taxes

14. Income Taxes

The effective tax rate for the three months ended September 30, 2011 was 4.4%. The effective tax rate for the nine months ended September 30, 2011 was 22.4%. The effective tax rate in both periods of 2011 was positively impacted by the release of a $3.1 million liability due to the expiration of a contractual obligation related to the transfer of certain intellectual property rights from US to non-US entities. The effective tax rate for the nine months ended September 30, 2011 was also positively impacted by the favorable adjustment of $3.9 million to the Company’s uncertain tax positions, partially offset by a reversal of related deferred tax assets of $1.7 million. The accrual for uncertain tax positions and related deferred tax assets are no longer required as the statute of limitations expired for the tax returns to which they are associated during the nine months ended September 30, 2011. The earnings (losses) of the Company’s foreign entities for the three and nine months ended September 30, 2011 were $(0.2) million and $10.2 million, respectively. The tax rates in the foreign jurisdictions in which the Company operates are less than the Company’s domestic rate, therefore, losses in the foreign jurisdictions will have a negative impact on the Company’s effective tax rate, while earnings in the foreign jurisdictions will have a positive impact on the Company’s effective tax rate.

The effective tax rate for the three months ended September 30, 2010 was 58.3%. The effective tax rate for the nine months ended September 30, 2010 was 98.5%. The effective tax rate in both periods in 2010 were negatively impacted by the Company’s inability to recognize income tax benefits during the period on losses sustained in certain tax foreign jurisdictions where the future utilization of the losses are uncertain, and by the recognition of tax expense associated with the transfer of certain intellectual property rights from U.S. to non-U.S. entities.

The Company’s effective tax rate could fluctuate significantly on a quarterly basis and could be adversely affected to the extent earnings are lower in the countries in which it operates that have a lower statutory rate or higher in the countries in which it operates that have a higher statutory rate or the extent it has losses sustained in countries where the future utilization of losses are uncertain. The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes.

The amount of unrecognized tax benefits for uncertain tax positions was $3.9 million as of September 30, 2011 and $8.4 million as of December 31, 2010, excluding related liabilities for interest and penalties of $2.2 million as of September 30, 2011 and December 31, 2010.

The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $2.7 million, due to the settlement of various audits and the expiration of statutes of limitation.

S1 Corporation

On October 3, 2011, the Company and S1 Corporation (“S1”) announced that they had entered into a definitive transaction agreement. The Company will acquire S1 for approximately $364 million in cash and 5.9 million shares of the Company’s stock. Under the terms of the transaction, S1 stockholders can elect to receive $10.00 in cash or 0.3148 shares of the Company’s stock for each S1 share they own, subject to proration, such that in the aggregate 33.8% of S1 shares are exchanged for the Company’s shares and 66.2% are exchanged for cash.

Based on the closing sales price of the Company’s common stock on September 30, 2011, the blended value of the Company’s proposal is $9.55 per S1 share, assuming full proration. This price will fluctuate with changes in the trading price of the Company’s common stock until the transaction close date.

The Company intends to use $90 million of its current cash balance for the acquisition. The Company has obtained commitments from Wells Fargo Securities, LLC to arrange, and Wells Fargo to provide, subject to certain conditions, senior bank financing consisting of up to $450 million under a proposed new secured credit facility, comprising of a $200 million senior secured term loan (the “Term Facility”) and a $250 million senior secured revolving credit facility (the “Revolving Facility” and, together with the Term Facility, the “Loan Facility”) for financing the remainder of the cash component of the consideration to be paid to S1’s stockholders in connection with the transaction agreement. Additionally, the Company will have the right, but not the obligation, to increase the amount of the Loan Facility by incurring an incremental term loan facility or increasing the Revolving Facility in an aggregate principal amount not to exceed $75 million, subject to certain conditions and under terms to be determined.

The transaction is subject to satisfaction of customary closing conditions, including the expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act, and, if applicable, the termination or expiration of any agreement with the Federal Trade Commission or the Antitrust Division of the U.S. Department of Justice not to accept S1 shares for exchange or otherwise consummate the acquisition contemplated by the definitive transaction agreement.

The disclosures which may be required or desired include: (1) for assets and liabilities measured on a recurring basis, disclosure may include: (a) the fair value measurements at the reporting date; (b) the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3); (c) for fair value measurements using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following: (i) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets), and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (ii) purchases, sales, issuances, and settlements (net); (iii) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs); (d) the amount of the total gains or losses for the period in subparagraph (c) (i) above included in earnings (or changes in net assets) that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date and a description of where those unrealized gains or losses are reported in the statement of income (or activities); (e) the valuation technique(s) used to measure fair value and a discussion of changes in valuation techniques, if any, during the period and (2) for assets and liabilities that are measured at fair value on a nonrecurring basis (for example, impaired assets) disclosure may include, in addition to (a) above: (a) the reasons for the fair value measurements recorded; (b) the same as (b) above; (c) for fair value measurements using significant unobservable inputs (Level 3), a description of the inputs and the information used to develop the inputs; and (d) the valuation technique(s) used to measure fair value and a discussion of changes, if any, in the valuation technique(s) used to measure similar assets and/or liabilities in prior periods. Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.
