	Summary of Significant Accounting Policies
	Basis of Presentation and Summary of Accounting Policies
	All amounts included herein related to the condensed consolidated financial statements as of September 30, 2014 and the three and nine months ended September 30, 2014 and 2013 are unaudited and should be read in conjunction with the audited consolidated financial statements and the notes thereto included in Callidus Software Inc.'s ("the Company") Annual Report on Form 10-K for the year ended December 31, 2013. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to the Securities and Exchange Commission ("SEC") rules and regulations regarding interim financial statements.
	In the opinion of management, the accompanying condensed consolidated financial statements include all necessary adjustments for the fair presentation of the Company’s financial position, results of operations and cash flows. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the full fiscal year ending December 31, 2014.
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, which include wholly-owned subsidiaries in Australia, Canada, Germany, Hong Kong, India, Japan, Malaysia, Mexico, New Zealand, Netherlands, Serbia, Singapore, and the United Kingdom. All intercompany transactions and balances have been eliminated upon consolidation.
	Use of Estimates
	Preparation of the condensed consolidated financial statements in conformity with GAAP and the rules and regulations of the SEC requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, the reported amounts of revenue and expenses during the reporting period and the accompanying notes. Estimates are used for, but not limited to, uncertain tax liabilities, allowances for doubtful accounts, the useful lives of fixed assets and intangible assets, goodwill and intangible asset impairments, stock-based compensation forfeiture rates, accrued liabilities, the allocation of the value of purchase consideration for business acquisitions, and other contingencies. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates such estimates and assumptions on an ongoing basis for continued reasonableness, using historical experience and other factors, including the current economic environment. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such evaluation. Illiquid credit markets, volatile equity and foreign currency markets and declines in information technology spending by prospective customers have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ materially from those estimates. Changes in those estimates, if any, resulting from continuing changes in the economic environment, will be reflected in the condensed consolidated financial statements in future periods.
	Recent Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09) "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605)”, and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on the consolidated financial statements.

Restructuring	'
	Restructuring and Other
	During the three months ended June 30, 2014, management approved and initiated restructuring plans to realign our resources to improve cost efficiencies. Restructuring and other expenses primarily consist of costs associated with exit of excess facilities, employee terminations and incremental depreciation expense as a result of the change in the estimated useful life of assets to be abandoned. The Company incurred restructuring and other expense of $0.3 million and $0.1 million during the three months ended September 30, 2014 and 2013, respectively, and $0.7 million and $1.7 million during the nine months ended September 30, 2014 and 2013, respectively.
	The following tables set forth a summary of accrued restructuring expenses for the nine months ended September 30, 2014 and 2013, respectively (in thousands):
		31-Dec-13		Additions		Adjustments			Cash			September 30, 2014

	Total accrued restructuring expenses	$	375	$	232	$	20		$	(350	)	$	277
	During the three and nine months ended September 30, 2014, the Company also incurred $0.3 million and $0.5 million of non-cash expense, respectively, primarily related to incremental depreciation expense as a result of the change in the estimated useful life of assets at the current headquarters in Pleasanton, CA.

	Acquisitions
	Clicktools Ltd.
	On September 16, 2014, the Company acquired Clicktools Ltd. (“Clicktools”), a provider of premium, cloud-based survey products and services for businesses. The purchase consideration was $16.4 million, which included $14.8 million paid in cash and $1.6 million as an indemnity holdback payable upon the one year closing anniversary, which remains outstanding as of September 30, 2014.
	The preliminary purchase price allocation for Clicktools is summarized as follows (in thousands):
		Fair Value
	Net assets assumed	$	394
	Intangible assets	3,100
	Goodwill	12,911
	Total purchase price	$	16,405
	The excess of purchase consideration over the fair value of net tangible assets assumed and identifiable intangible assets acquired was recorded as goodwill. Goodwill is primarily attributed to the anticipated synergies from the acquisition and expanded market opportunities with respect to the integration of Clicktools' business-to-business survey management platform with the Company’s other solutions. The goodwill balance is not deductible for U.S. income tax purposes.
	Due to the recent closing of the Clicktools acquisition at quarter-end, the initial allocation of the purchase price is pending the completion of various analysis and finalization of estimates. The Company expects to finalize the valuation, including deferred revenue, as soon as practicable, but no later than one-year from the acquisition date.
	The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the date of the Clicktools acquisition (in thousands):
		Fair Value			Useful Life
	Developed technology	$	1,400		5 years
	Domain names and trademarks	600			3 years
	Customer relationships	1,100			3 years
	Total intangible assets subject to amortization	$	3,100
	Pro forma results of operations for the Clicktools acquisition have not been presented because the acquisition is not material.
	LeadRocket, Inc.
	On February 4, 2014, the Company acquired all of the common stock of LeadRocket, Inc. (“LeadRocket”), a privately-held company providing marketing automation and demand generation solutions that enable both marketing and sales users to identify and connect with leads efficiently. The Company acquired LeadRocket to strengthen its social engagement and digital marketing platform. The purchase consideration was $3.0 million, which included $2.5 million paid in cash and $0.5 million as indemnity holdback payable upon the one year closing anniversary. As of September 30, 2014, $0.4 million of the indemnity holdback remains accrued for potential indemnification claims, and the timing and amount of any additional indemnification items under the holdback is unknown.
	The preliminary purchase price allocation for LeadRocket is summarized as follows (in thousands):
		Fair Value
	Net liabilities assumed	$	(1,075	)
	Intangible assets	2,640
	Goodwill	1,584
	Deferred tax liabilities	(149		)
	Total purchase price	$	3,000
	The excess of purchase consideration over the fair value of net tangible liabilities assumed and identifiable intangible assets acquired was recorded as goodwill. The fair values assigned to tangible and identifiable intangible assets acquired and liabilities assumed are based on management’s estimates and assumptions. The estimated fair values of assets acquired and liabilities assumed, specifically current and noncurrent income taxes payable and deferred taxes, may be subject to change as additional information is received and certain tax returns are finalized. Thus the provisional measurements of fair value set forth above are subject to change. The Company expects to finalize the valuation as soon as practicable, but no later than one-year from the acquisition date.
	The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the date of the LeadRocket acquisition (in thousands):
		Fair Value			Useful Life
	Developed technology	$	570		2-4 years
	Patents	1,060			10 years
	Domain names and trademarks	850			5 years
	Customer relationships	160			3 years
	Total intangible assets subject to amortization	$	2,640
	The goodwill balance is primarily attributed to the anticipated synergies from the acquisition and expanded market opportunities with respect to the integration of LeadRocket’s digital marketing platform with the Company’s other solutions. The goodwill balance is not deductible for U.S. income tax purposes.
	Pro forma results of operations for the LeadRocket acquisition have not been presented because the acquisition is not material.
	Goodwill
	Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. Goodwill amounts are not amortized, but rather tested for impairment at least annually or as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.
	As of September 30, 2014 and December 31, 2013, goodwill consisted of the following (in thousands):
	Balance as of December 31, 2013	$	31,207
	LeadRocket	1,584
	Clicktools	$	12,911
	Foreign currency translation impact	$	(18	)
	Balance as of September 30, 2014	$	45,684

	As of September 30, 2014 and December 31, 2013, all investment debt securities are classified as available-for-sale and carried at estimated fair value, which is determined based on the inputs discussed below.
	The Company classifies all highly liquid instruments with an original maturity on the date of purchase of three months or less as cash and cash equivalents.  The Company classifies available-for-sale securities that have a maturity date longer than three months as short-term investments, including those investments with a maturity date of longer than one year that are highly liquid and which the Company does not intend to hold to maturity.
	Realized gains and losses are calculated using the specific identification method. As of September 30, 2014 and December 31, 2013, the Company had no short-term investments in a material unrealized loss position.
	The components of the Company’s cash, cash equivalents, and investments classified as available-for-sale were as follows at September 30, 2014 and December 31, 2013 (in thousands):

	Total	$	2,778		$	2,774
	At September 30, 2014, the Company had no material unrealized losses on our short-term investments.
	The Company had no realized gains or losses on sales of its investments for the three and nine months ended September 30, 2014 and 2013. The Company had proceeds, net of purchases of investments, of $5.1 million and $3.8 million from maturities and sales of investments during the nine months ended September 30, 2014 and 2013, respectively.
	The short-term investments in government obligations or highly rated credit securities generally have minor to moderate fluctuations in the fair values from period to period. The Company monitors credit ratings, downgrades and significant events surrounding these securities so as to assess if any of the impairments will be considered other-than-temporary. The Company did not identify any government obligations or highly rated credit securities held as of September 30, 2014 or as of December 31, 2013 for which the fair value declined significantly below amortized cost and were considered other-than-temporary impairments.

The Company values these securities using a pricing matrix from a pricing service provider, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs). The Company classifies all of its available-for-sale securities, except for money market funds, as having Level 2 inputs. The Company validates the estimated fair value of certain securities from a pricing service provider on a quarterly basis. The valuation techniques used to measure the fair value of the financial instruments having Level 2 inputs, all of which have counterparties with high credit ratings, were derived from the following: non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments or pricing models, such as discounted cash flow techniques, with all significant inputs derived from or corroborated by observable market data.
	Level 3
	As of September 30, 2014, the Company had no Level 3 instruments. The Company did not have any transfers between Level 1, Level 2 and Level 3 fair value measurements during the periods presented as there were no changes in the composition in Level 1, 2 or 3.

Please also refer to Note 13 - Subsequent Event for additional commitments that the Company has entered into subsequent to September 30, 2014.
	Revolving Line of Credit
	In May 2014, the Company entered into a credit agreement with Wells Fargo Bank, National Association ("Lender"), under which the Lender agreed to make a revolving loan ("Revolver") to the Company in an amount not to exceed $10.0 million, with an accordion feature that allows the Company to increase the maximum borrowing amount by not less than $5.0 million and not more than $10.0 million. The Revolver matures in May 2019. Outstanding borrowings under the Revolver bear interest, at the Company's option, at a base rate plus an applicable margin. The applicable margin ranges between 0.75% and 2.25% depending on the Company's leverage ratio. Interest is payable every three months.
	During the three months ended September 30, 2014, the Company increased the maximum borrowing amount under the Revolver to $15.0 million.
	As of September 30, 2014, the Company had borrowed $10.5 million under the Revolver. The carrying value of total debt approximates fair market value.
	Letter of Credit
	During the three months ended September 30, 2014, the Company reduced the security deposit from $0.4 million to $0.2 million for its current headquarters office at 6200 Stoneridge Mall Road, Suite 500, Pleasanton, California 94588. As a result, $0.4 million was released to the Company in cash, and the Company obtained a $0.2 million letter of credit in August 2014 for the security deposit. The letter of credit will expire on August 31, 2015.
	Financing Arrangement for Equipment Purchase
	In September 2014, the Company entered into a financing arrangement for the purchase of storage equipment, primarily for its data centers. The principal amount financed is $3.8 million and is payable in two installments of $2.6 million and $1.2 million in three months and one year, respectively, from November 2014. The financing arrangement does not bear interest. There are no financial covenants associated with the financing arrangement. In the event of default by the Company, the financing company may repossess the equipment and sell it in the in order to offset the Company’s liability to it. As of September 31, 2014, the Company had received, and accrued for, $0.1 million of storage equipment. Any shortfall from the sale of the equipment will be due and payable by the Company to the financing company.
	Warranties and Indemnification
	The Company generally warrants that its software will perform in accordance with its standard documentation. Under the Company’s standard warranty, should a software product not perform as specified in the documentation within the warranty period, the Company will repair or replace the software or refund the license fee paid. To date, the Company has not incurred any incremental costs related to warranty obligations for its software.
	The Company’s product license and on-demand agreements typically include a limited indemnification provision for claims by third parties relating to the Company’s intellectual property. To date, the Company has not incurred material costs, and has not accrued any costs related to such indemnification provisions.
	Intellectual Property Litigation
	Versata Software, Inc. and Versata Development Group, Inc. v. Callidus Software, Inc. - Ongoing
	On July 19, 2012, Versata Software, Inc. and Versata Development Group, Inc. (collectively, “Versata”) filed suit against Callidus in the United States District Court for the District of Delaware (“Delaware District Court”). The suit asserts that the Company infringes U.S. Patent Nos. 7,904,326, 7,908,304 and 7,958,024. The Company believes that the claims are without merit and intends to vigorously defend against these claims. On May 30, 2013, the Company answered the complaint and filed a counterclaim against Versata in the Delaware District Court. The Company's counterclaim asserts that Versata infringes U.S. Patent Nos. 6,269,355, 6,850,924 and 6,473,748. On August 30, 2013, the Company filed petitions with the United States Patent and Trademark Office Patent Trial and Appeal Board (“PTAB”) for covered business method (“CBM”) patent review of U.S. Patent Nos. 7,904,326, 7,908,304 and 7,958,024, which Versata filed responses to on December 12, 2013. The Company also filed a motion with the Delaware District Court on August 30, 2013 to stay the litigation pending completion of the patent review proceedings with the PTAB (“Motion to Stay”). On January 8, 2014, the Company was granted leave by the Delaware District Court to add Versata Inc. as a counterclaim defendant. On March 4, 2014, the PTAB instituted covered business method patent review of each of Versata’s patents, namely, U.S. Patent Nos. 7,904,326, 7,908,304 and 7,958,024, finding that it is more likely than not that the Company will prevail in establishing that the challenged claims are not patentable. After requesting that the PTAB reconsider its decision to institute, which was denied, Versata filed a petition for writ of mandamus with the Court of Appeals for the Federal Circuit (“CAFC”) on April 11, 2014 asking that Court to deny institution of CBM patent review by the PTAB. The CAFC denied Versata’s petition for writ of mandamus on May 5, 2014. On April 17, 2014, the Company filed additional petitions with the PTAB for CBM patent review to address all of the remaining claims not previously covered in the prior petitions with respect to U.S Patent Nos. 7,908,304 and 7,958,024. On May 8, 2014, the Delaware District Court: (i) granted the Company’s Motion to Stay in part with respect to U.S. Patent No. 7,904,326, and (ii) denied the Company’s Motion to Stay in part with respect to U.S. Patent Nos. 7,908,304 and 7,958,024. On May 8, 2014, the Company appealed to the CAFC the Delaware District Court’s denial of the Motion to Stay with respect to U.S. Patent Nos. 7,908,304 and 7,958,024. On October 2, 2014, the PTAB instituted covered business method patent review of the remaining claims covered in the second set of petitions for U.S Patent Nos. 7,908,304 and 7,958,024. On October 21, 2014, the Company and Versata engaged in a mediation to settle their present dispute and to reach global settlement to avoid future patent infringement lawsuits. Following the mediation, considering all facts and circumstances, the Company determined that it had incurred a liability as of September 30, 2014 and recorded an estimated potential loss for this case in the amount of $3.0 million. The estimated potential loss was recorded to cost of recurring revenue and to general and administrative expenses in the amounts of $1.2 million and $1.8 million, respectively.
	Other Matters
	In addition to the above litigation matter, the Company is from time to time a party to other various litigation and customer disputes incidental to the conduct of its business. At the present time, the Company believes that none of these matters are likely to have a material adverse effect on the Company’s future financial results.
	The Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Company reviews the need for any such liability on a quarterly basis and records any necessary adjustments to reflect the effect of ongoing negotiations, contract disputes, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case in the period they become known. At September 30, 2014, the Company had not recorded any such liabilities in accordance with accounting for contingencies. However, litigation and other disputes are subject to inherent uncertainties and the Company's view on these matters may change in the future.

	Net Loss Per Share
	Basic net loss per share is calculated by dividing net loss for the period by the weighted average common shares outstanding during the period. Diluted net loss per share is calculated by dividing the net loss for the period by the weighted average common shares outstanding, adjusted for all dilutive potential common shares, which includes shares issuable for the period of time the Convertible Notes were outstanding, the exercise of outstanding common stock options, the release of restricted stock units, and purchases of shares pursuant to our employee stock purchase plan ("ESPP"), to the extent these shares are dilutive. For the three and nine months ended September 30, 2014 and 2013, the diluted net loss per share calculation was the same as the basic net loss per share calculation as all potential common shares were anti-dilutive.
	Diluted net loss per share does not include the effect of the following potential weighted average common shares because to do so would be anti-dilutive for the periods presented (in thousands):

	Performance Awards
	In 2014, the Company granted performance awards with vesting contingent on absolute SaaS revenue growth over the three year period from 2014 through 2016, and the Company’s relative total stockholder return over the three year period from 2014 through 2016 versus an index of 17 SaaS companies.
	In 2013, the Company granted performance awards with vesting contingent on successful attainment of pre-set SaaS revenue growth and recurring revenue gross profit targets.
	Determination of Fair Value
	The fair value of service-based awards is estimated based on the market value of the Company’s stock on the date of grant. A portion of the performance awards granted during 2014 are based on relative stockholder return and therefore, are subject to a market condition. As a result, the fair value of performance awards is calculated using a Monte Carlo simulation model that estimates the distribution of the potential outcomes of the grants of performance awards based on simulated future index of the peer companies.
	The fair value of each stock option is estimated on the date of grant using the Black-Scholes valuation model and the assumptions noted in the following table. No stock options were granted during the three and nine months ended September 30, 2014.

	Income tax expense for the three and nine months ended September 30, 2014 was $0.3 million and $0.9 million, compared to income tax expense of $0.5 million and $1.7 million for the same periods of 2013. The decrease for the three and nine month periods was primarily due to a decrease in the withholding taxes in the foreign jurisdictions. The decrease for the nine months ended September 30, 2014 was also impacted by the release in the three months ended September 30, 2014 of a portion of the valuation allowance associated with the acquisition of LeadRocket and the mix of foreign earnings and tax rates.

	New Headquarters Building Lease
	In October 2014, the Company entered into a sublease agreement ("Sublease") with Oracle America, Inc. (“Sublandlord”) for office space located at 4140 Dublin Boulevard, Dublin, California 94568 ("Subleased Premises"), to replace the Company’s current corporate headquarters.
	The term of the Sublease commences on the date the Sublandlord delivers possession of the Subleased Premises to the Company and expires on May 15, 2022. The Company expects to receive possession within the next twelve months. Base rent will be abated from the commencement of the Sublease until November 30, 2015. Thereafter, monthly base rent will be $149,928 for 2015 and increase annually as set forth in the Sublease, up to $184,411 in 2022. The total cash obligation for base rent over the term of the Sublease is approximately $15.1 million, without rent abatement. In addition to base rent, the Company will be required to pay its pro rata share of building operating costs including utilities, insurance, repair and personnel costs, along with real estate taxes in excess of the amounts for certain base years.
	Amendment to Current Headquarters Lease
	In October 2014, in connection with the execution of the Sublease, the Company and the current landlord entered into the Third Amendment to Lease (“Lease Amendment”) to amend the Office Lease Agreement between the Company and current landlord, dated March 30, 2010, as amended (“Current Lease”), for the Company’s current headquarters at 6200 Stoneridge Mall Road, Suite 500, Pleasanton, California 94588 (“Current Premises”).

Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to the Securities and Exchange Commission ("SEC") rules and regulations regarding interim financial statements.
	In the opinion of management, the accompanying condensed consolidated financial statements include all necessary adjustments for the fair presentation of the Company’s financial position, results of operations and cash flows. The results of operations for the interim periods presented are not necessarily indicative of the operating results to be expected for any subsequent interim period or for the full fiscal year ending December 31, 2014.
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, which include wholly-owned subsidiaries in Australia, Canada, Germany, Hong Kong, India, Japan, Malaysia, Mexico, New Zealand, Netherlands, Serbia, Singapore, and the United Kingdom. All intercompany transactions and balances have been eliminated upon consolidation.
Use of Estimates	'
	Use of Estimates
	Preparation of the condensed consolidated financial statements in conformity with GAAP and the rules and regulations of the SEC requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, the reported amounts of revenue and expenses during the reporting period and the accompanying notes. Estimates are used for, but not limited to, uncertain tax liabilities, allowances for doubtful accounts, the useful lives of fixed assets and intangible assets, goodwill and intangible asset impairments, stock-based compensation forfeiture rates, accrued liabilities, the allocation of the value of purchase consideration for business acquisitions, and other contingencies. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates such estimates and assumptions on an ongoing basis for continued reasonableness, using historical experience and other factors, including the current economic environment. Appropriate adjustments, if any, to the estimates used are made prospectively based upon such evaluation. Illiquid credit markets, volatile equity and foreign currency markets and declines in information technology spending by prospective customers have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ materially from those estimates. Changes in those estimates, if any, resulting from continuing changes in the economic environment, will be reflected in the condensed consolidated financial statements in future periods.
Recently Adopted Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09 (ASU 2014-09) "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605)”, and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The Company is currently in the process of evaluating the impact of the adoption of ASU 2014-09 on the consolidated financial statements.
