FinancialL Statement Presentation	'

	1.FINANCIAL STATEMENT PRESENTATION
	The accompanying unaudited condensed consolidated financial statements of Interactive Intelligence Group, Inc. (“the Company”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and with the instructions for Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, certain information and note disclosures normally included in the Company’s financial statements prepared in accordance with GAAP have been condensed, or omitted, pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”).

	The preparation of the Company’s condensed consolidated financial statements requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, at the respective balance sheet dates, and the reported amounts of revenues and expenses during the respective reporting periods. Despite management’s best effort to establish good faith estimates and assumptions, actual results could differ from these estimates. In management’s opinion, the Company’s accompanying condensed consolidated financial statements include all adjustments necessary (which are of a normal and recurring nature, except as otherwise noted) for the fair presentation of the results of the interim periods presented.

	The Company’s accompanying condensed consolidated financial statements as of December 31, 2012 have been derived from the Company’s audited consolidated financial statements at that date but do not include all of the information and notes required by GAAP for complete financial statements. These accompanying condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2012, included in the Company’s most recent Annual Report on Form 10-K as filed with the SEC on March 18, 2013. The Company’s results of operations for any interim period are not necessarily indicative of the results of operations for any other interim period or for a full fiscal year.

	Principles of Consolidation

	The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after elimination of all significant intercompany accounts and transactions.

	Reclassification and Adjustments

	Effective January 1, 2013, the Company reclassified certain expenses which were included in cost of services in prior periods to sales and marketing expenses. In prior years, these costs were not significant; however, as these costs have continued to increase in line with the Company’s growth strategy, the Company concluded that it is appropriate to report these expenses as sales and marketing. For the three and nine months ended September 30, 2012, $508,000 and $1.2 million, respectively, has been reclassified to sales and marketing expenses based on this new expense presentation. The reclassification did not have any impact on the overall results previously reported.

	During the second quarter of 2013, the Company reclassified liabilities related to straight-line rent accruals which were included in accrued liabilities to other long-term liabilities. In the condensed consolidated balance sheet at December 31, 2012, $3.4 million has been reclassified to other long-term liabilities. This reclassification did not have a material impact on the overall results previously reported.

Summary Of Certain Accounting Policies And Recent Accounting Pronouncements	'

	2.SUMMARY OF CERTAIN ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS

	For a complete summary of the Company’s significant accounting policies and critical accounting estimates, refer to Note 2 of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

	In July 2012, the Financial Accounting Standards Board (“the FASB”) issued FASB Accounting Standards Update (“ASU”) 2012-02, Intangibles – Testing Indefinite-Lived Intangible Assets for Impairment, which amends FASB Accounting Standards Codification (“ASC”) Topic 350, Intangibles – Goodwill and Other. This updated guidance allows an entity to first assess qualitative factors to determine whether it is necessary to perform a quantitative impairment test. Under the amended guidance, an entity would not be required to calculate the fair value of an indefinite-lived intangible asset unless the entity determines, based on a qualitative assessment, that it is more likely than not that the indefinite-lived intangible asset is impaired. The amendments include a number of events and circumstances for an entity to consider in conducting the qualitative assessment. The guidance applies to both public and non-public entities and is effective for annual and interim goodwill impairment tests performed in fiscal years beginning after September 15, 2012. Early adoption is permitted. The Company adopted this guidance in the first quarter of 2013 and noted no material impact on its consolidated financial statements upon adoption.

	In February 2013, the FASB issued FASB ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (Topic 220). The amendments in this update supersede and replace the presentation requirements for reclassifications out of accumulated other comprehensive income in FASB ASUs 2011-05 and 2011-12 for all public and private organizations. The amendments require an entity to provide additional information about reclassifications out of accumulated other comprehensive income. The guidance became effective for public entities for fiscal years and interim periods beginning after December 15, 2012. The Company adopted this guidance in the first quarter of 2013 and noted no material impact on its consolidated financial statements upon adoption.

	In July 2013, the FASB issued FASB ASU 2013-11, Income Taxes. This updated guidance requires an entity to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss (NOL) carryforward, or similar tax loss or tax credit carryforward, rather than as a liability when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) the entity intends to use the deferred tax asset for that purpose. This ASU does not require new recurring disclosures. The Company will adopt this guidance during the fourth quarter of 2013 and does not expect that there will be a material impact on its consolidated financial statements upon adoption.

	The Company capitalizes costs related to its cloud-based services and certain projects for internal use in accordance with FASB ASC 350-40, Internal Use Software. Once an application has reached the development stage, internal and external costs, if direct and incremental, are capitalized until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing. Costs incurred in the preliminary stages of development, maintenance and training costs are expensed as incurred. During the nine months ended September 30, 2013, the Company capitalized $1.7 million of year-to-date costs related to the development of its cloud-based offering. The Company will continue to capitalize development costs related to this project and will begin amortizing such costs once the software is ready for production, which is expected to be mid-2014.

	During the nine months ended September 30, 2013, there were no other material changes to the Company’s significant accounting policies or critical accounting estimates.

	3.INVESTMENTS

	FASB ASC 820, as amended, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes the following three levels of inputs that may be used to measure fair value:

	·	Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

	·	Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

	·	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

	The Company’s short-term investments all mature in less than one year and its long-term investments all mature within three years. Both short-term and long-term investments are considered available for sale. The Company’s assets that are measured at fair value on a recurring basis are classified within Level 1 or Level 2 of the fair value hierarchy. The types of instruments valued based on quoted market prices in active markets include money market securities. Such instruments are classified within Level 1 of the fair value hierarchy. The Company invests in money market funds that are traded daily and does not adjust the quoted price for such instruments. The types of instruments valued based on quoted prices in less active markets, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include corporate notes, agency bonds, commercial paper, certificates of deposit, and international government bonds. Such instruments are classified within Level 2 of the fair value hierarchy. The Company uses consensus pricing, which is based on multiple pricing sources, to value its fixed income investments.

	The following table sets forth a summary of the Company’s financial assets, classified as cash and cash equivalents, short-term investments and long-term investments on its condensed consolidated balance sheets, measured at fair value as of September 30, 2013 and December 31, 2012 (in thousands):

	4.NET INCOME (LOSS) PER SHARE

	Basic net income (loss) per share is calculated based on the weighted-average number of common shares outstanding in accordance with FASB ASC Topic 260, Earnings per Share. Diluted net income per share is calculated based on the weighted-average number of common shares outstanding plus the effect of dilutive potential common shares. Potential common shares consist of shares of common stock issuable upon the exercise of stock options and vesting of restricted stock units (“RSUs”). The calculation of diluted net income per share excludes shares underlying stock options outstanding that would be anti-dilutive. When the Company reports a net loss, the calculation of diluted net loss per share excludes potential common shares as the effect would be anti-dilutive. The following table sets forth the calculation of basic and diluted net income (loss) per share (in thousands, except per share amounts):


		Three Months Ended September 30				Nine Months Ended September 30,
		2013		2012		2013		2012
	Net income (loss), as reported (A)	$	1,627	$	-445	$	5,985	$	-1,364

	Weighted average shares of common stock outstanding (B)		20,112		19,283		19,922		19,199
	Dilutive effect of employee stock options and RSUs		1,068		-		1,056		-
	Common stock and common stock equivalents (C)		21,180		19,283		20,978		19,199

	Net income (loss) per share:
	Basic (A/B)	$	0.08	$	-0.02	$	0.30	$	-0.07
	Diluted (A/C)		0.08		-0.02		0.29		-0.07

	The Company’s calculation of diluted net income per share for the three and nine months ended September 30, 2013 excludes stock options to purchase approximately 40,000 and 212,000 shares of the Company’s common stock, respectively, as their effect would be anti-dilutive.

	5	STOCK-BASED COMPENSATION

	Stock Option Plans

	The Company’s stock option plans, adopted in 1995, 1999 and 2006, authorize the Board of Directors or the Compensation Committee, as applicable, to grant incentive and nonqualified stock options, and, in the case of the 2006 Equity Incentive Plan, as amended and as assumed by the Company (the “2006 Plan”), stock appreciation rights, restricted stock, RSUs, performance shares, performance units and other stock-based awards. After adoption of the 2006 Plan by the Company’s shareholders in May 2006, the Company may no longer make any grants under previous plans, but any shares subject to awards under the 1999 Stock Option and Incentive Plan and the Outside Directors Stock Option Plan (collectively, the “1999 Plans”) that are cancelled are added to shares available under the 2006 Plan. At the Company’s 2013 Annual Meeting of Shareholders held on May 22, 2013, the Company’s shareholders approved an amendment to the 2006 Plan to increase the number of shares available for issuance under the 2006 Plan by 2,000,000 shares. A maximum of 9,050,933 shares are available for delivery under the 2006 Plan, which consists of (i) 5,350,000 shares, plus (ii) 320,000 shares available for issuance under the 1999 Plans, but not underlying any outstanding stock options or other awards under the 1999 Plans, plus (iii) up to 3,380,933 shares subject to outstanding stock options or other awards under the 1999 Plans that expire, are forfeited or otherwise terminate unexercised on or after May 18, 2006. The number of shares available under the 2006 Plan is subject to adjustment for certain changes in the Company’s capital structure. The exercise price of options granted under the 2006 Plan is equal to the closing price of the Company’s common stock, as reported by The NASDAQ Global Select Market, on the business day immediately preceding the date of grant. As of September 30, 2013, there were 2,312,756 shares of stock available for issuance for equity compensation awards under the 2006 Plan.

	The Company grants RSUs and three types of stock options. The first type of stock option is non-performance-based subject only to time-based vesting, and these stock options are granted by the Company as annual grants to executives, to certain new employees and to newly-elected non-employee directors. These stock options vest in four equal annual installments beginning one year after the grant date. The fair value of these option grants is determined on the date of grant and the related compensation expense is recognized for the entire award on a straight-line basis over the requisite service period.

	The second type of stock option granted by the Company is performance-based subject to cancellation if the specified performance targets are not met. If the applicable performance targets have been achieved, the options will vest in four equal annual installments beginning one year after the performance-related period has ended. The fair value of these stock option grants is determined on the date of grant and the related compensation expense is recognized over the requisite service period, including the initial period for which the specified performance targets must be met.

	The third type of stock option granted by the Company is director options granted to non-employee directors annually. These options are similar to the non-performance-based options described above except that the director options vest one year after the grant date. The fair value of these option grants is determined on the date of the grant and the related compensation expense is recognized over one year. These director options are generally granted at the Company’s Annual Meeting of Shareholders during the second quarter of each fiscal year.

	The Company grants RSUs to certain key employees, executives and certain new employees. The fair value of the RSUs is determined on the date of grant and the RSUs vest in four equal annual installments beginning one year after the grant date. RSUs are not included in issued and outstanding common stock until the shares are vested and settlement has occurred.

	The plans may be terminated by the Company’s Board of Directors at any time.

	Stock Option and RSU Valuation

	The Company estimated the fair value of stock options using the Black-Scholes valuation model. There were no material changes in the way the assumptions were calculated as previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. Non-performance-based options can be granted to all employees and newly-elected non-employee directors throughout the year, while performance-based options are only granted to sales and marketing employees during the first quarter of each year and annual option grants to non-employee directors only occur during the second quarter of each year. The weighted-average estimated per option value of each category of options granted during the nine months ended September 30, 2013 and 2012 used the following assumptions:

	6.ACCOUNTS RECEIVABLE AND CONCENTRATION OF CREDIT RISK

	The Company records unbilled accounts receivable which represents amounts recognized as revenues for invoices that have not yet been sent to customers. This balance fluctuates depending on the contractual billing milestones and work performed related to projects specified in the contract. When the work performed is ahead of the billing milestones related to a services engagement, unbilled accounts receivable will be recorded. The balance of unbilled accounts receivable recorded as of September 30, 2013 was $7.5 million.

	No customer or partner accounted for more than 10% of the Company’s accounts receivable as of September 30, 2013 or December 31, 2012 or for more than 10% of the Company’s revenues for the three and nine months ended September 30, 2013 or 2012. The Company’s top five customers collectively represented 21% and 22% of the Company’s accounts receivables balance at September 30, 2013 and December 31, 2012, respectively. No individual country accounted for more than 10% of the Company’s revenues except for the United States, which accounted for 65% of the Company’s revenues in both the three and nine months ended September 30, 2013 and 66% and 65% of the Company’s revenues in the three and nine months ended September 30, 2012, respectively.

	7.COMMITMENTS AND CONTINGENCIES
	Legal Proceedings

	From time to time, the Company receives notification from competitors and other technology providers claiming that the Company’s technology infringes upon their proprietary rights. The Company cannot provide assurance that these matters can be resolved amicably without litigation, or that the Company will be able to enter into licensing arrangements on terms and conditions that would not have a material adverse effect on its business, financial condition or results of operations.

	From time to time, the Company is also involved in certain legal proceedings in the ordinary course of conducting its business. While the ultimate liability pursuant to these actions cannot currently be determined, the Company believes these legal proceedings will not have a material adverse effect on its financial position or results of operations. Litigation, in general, and intellectual property litigation, in particular, can be expensive and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict.

	Guarantees
	The Company provides indemnifications of varying scope and amount to certain customers against claims of intellectual property infringement made by third parties arising from the use of its products. The Company’s direct software license agreements include certain provisions for indemnifying customers, in material compliance with their license agreement, against liabilities if the Company’s software products infringe upon a third party's intellectual property rights, over the life of the agreement. There is no maximum potential amount of future payments set under the guarantee. However, the Company may at any time and at its option and expense: (i) procure the right of the customer to continue to use the Company’s software that may infringe a third party’s rights; (ii) modify its software so as to avoid infringement; or (iii) require the customer to return its software and refund the customer the fee actually paid by the customer for its software less depreciation based on a five-year straight-line depreciation schedule. The customer’s failure to provide timely notice or reasonable assistance will relieve the Company of its obligations under this indemnification to the extent that it has been actually and materially prejudiced by such failure. To date, the Company has not incurred, nor does it expect to incur, any material related costs and, therefore, has not reserved for such liabilities, in accordance with FASB ASC Topic 460, Guarantees.
	The Company’s software license agreements also include a warranty that its software products will substantially conform to its software user documentation for a period of one year, provided the customer is in material compliance with the software license agreement. To date, the Company has not incurred any material costs associated with these product warranties, and as such, has not reserved for any such warranty liabilities in its operating results.
	Lease Commitments

	The Company leases space for its world headquarters in Indianapolis, Indiana under an operating lease agreement and amendments which expire on March 31, 2018. The Company also has multiple leases for offices and other space throughout the world. The office space for sales, services, development and international offices and a product distribution center located in Indianapolis, Indiana are rented under operating leases which expire at various times through 2016. In accordance with FASB ASC Topic 840, Leases, rental expense is recognized ratably over the lease period, including those leases containing escalation clauses.

	Other Contingencies

	The Company has received and may continue to receive certain payroll tax credits and real estate tax abatements that were granted to the Company based upon specified growth projections. If the Company’s actual performance is less than those projections, the Company may be subject to repayment of some or all of the tax credits or payment of additional real estate taxes in the case of the abatements. The Company does not believe that it will be subject to payment of any money related to these taxes; however, the Company cannot provide assurance as to the outcome.

	The Company’s effective tax rate for the three and nine months ended September 30, 2013 was 51.8% and 10.8%, respectively, compared to 33.9% and 29.9%, respectively, for the same periods in 2012. During the three months ended March 31, 2013, the Company recorded a $600,000 U.S. Federal research and development credit related to 2012. During the second quarter of 2013, the Company changed its transfer pricing methods with respect to its foreign subsidiaries, which change was retroactively applied to the first quarter of 2013 and full year 2012 and resulted in a $436,000 tax credit recorded in the three months ended June 30, 2013. During the quarter ended September 30, 2013, the Company recorded $372,000 in additional tax expense for adjustments resulting from an IRS audit related to the tax years ended December 31, 2010 and 2011. Without the effect of the 2012 research and development credit as a discrete item, the change in transfer pricing, and the adjustments related to the IRS audit, the Company’s effective tax rate for the nine months ended September 30, 2013 would have been 19.5%, primarily due to the allocation of book income between the Company’s US subsidiaries.

	10. Derivatives

	The Company enters into derivative contracts to mitigate its foreign currency risk associated with transacting business internationally. The Company uses foreign currency forward contracts to hedge the revaluation exposure of its net monetary assets and liabilities including cash, accounts receivable, accounts payable and certain intercompany payables and receivables. These hedges are not designated under GAAP, and all realized and unrealized gains and losses are recorded as incurred within other income (expense) on the Company’s condensed consolidated statements of operations and comprehensive income (loss). The objective is to offset the gains and losses on the underlying exposures with the gains and losses from the forward contracts. The Company’s hedging policy prohibits entering into hedge contracts that are speculative in nature.

	The Company records the fair value of its outstanding hedge contracts in other current assets and accrued liabilities depending upon the market value of the forward contracts at each balance sheet date. The following table summarizes the notional amount and fair value of the Company’s outstanding currency contracts at September 30, 2013 and December 31, 2012, respectively.
