Basis of Presentation	'
	Note 2. Basis of Presentation
	The consolidated financial statements include the accounts of Jive Software, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
	The accompanying consolidated financial statements and condensed footnotes have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included. The results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results to be expected for the full year. For further information, refer to the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013, which was filed with the Securities and Exchange Commission (the “SEC”) on March 3, 2014.
	The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities in the financial statements and the accompanying notes. Significant estimates include the estimates relating to:
		•	revenue recognition;
		•	the useful lives of fixed assets;
		•	stock-based compensation;
		•	contingent liabilities;
		•	assumptions used in testing for impairment of goodwill and other long-lived assets; and
		•	the recoverability of deferred income tax assets and liabilities.
	Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements.

	Restricted stock results from the exercise of unvested restricted stock purchases (“RSPs”) and non-qualified stock options (“NSOs”) with reverse vesting provisions, and the grant of restricted stock awards (“RSAs”), PSUs and RSUs. The shares of restricted stock vest over the period specified in the related RSP, NSO, RSA, PSU and RSU agreements. Restricted stock activity was as follows:

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Note 7. Fair Value Measurements
	Factors used in determining the fair value of financial assets and liabilities are summarized into three broad categories:
		•		Level 1 – quoted prices in active markets for identical securities as of the reporting date;
		•		Level 2 – other significant directly or indirectly observable inputs, including quoted prices for similar securities, interest rates, prepayment speeds and credit risk; and
		•		Level 3 – significant inputs that are generally less observable than objective sources, including our own assumptions in determining fair value.
	The factors or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
	The following tables present our financial assets and liabilities that are measured at fair value on a recurring basis (in thousands):

	We classify our marketable securities as available-for-sale and, accordingly, record them at fair value based on quoted market prices. Unrealized holding gains and losses are excluded from earnings and are reported as a separate component of Stockholders’ equity until realized. See the Consolidated Statements of Comprehensive Loss.
	There were no changes to our valuation techniques during the three months ended March 31, 2014.
	During the three months ended March 31, 2014 and 2013, we did not record any other-than-temporary impairments on those financial assets required to be measured at fair value on a nonrecurring basis.
	We recognize or disclose the fair value of certain assets such as non-financial assets, primarily long-lived assets, goodwill, intangible assets and certain other assets in connection with impairment evaluations. All of our nonrecurring valuations use significant unobservable inputs and therefore fall under Level 3 of the fair value hierarchy.
	The carrying value of our term loan approximates its fair value and falls under Level 2 of the fair value hierarchy, as the interest rate is variable and based on current market rates.

	We have a secured revolving loan facility and term loan facility of up to $30.0 million under a loan agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”), which expires by its terms on May 23, 2015.
	On February 18, 2014, we entered into a Second Loan Modification Agreement with SVB to modify the minimum adjusted EBITDA financial covenant for periods occurring after December 31, 2013 and remove the fixed charge coverage ratio and maximum leverage ratio financial covenants, which were set to begin in periods occurring after December 31, 2013.
	At March 31, 2014, we had $1.0 million of outstanding letters of credit, no revolving loans outstanding under the Loan Agreement and $7.8 million of term loans outstanding at an interest rate of 2.23%. We were in compliance with all covenants as of March 31, 2014.

Accounting Changes And Error Corrections [Abstract]	'
New Accounting Pronouncements	'
	Note 12. New Accounting Pronouncements
	Recently Adopted Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 amends the guidance related to the presentation of unrecognized tax benefits and allows for the reduction of a deferred tax asset for a net operating loss (“NOL”) carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. ASU 2013-11 is effective for annual and interim periods for fiscal years beginning after December 15, 2013, and early adoption is permitted. Since ASU 2013-11 relates only to the presentation of unrecognized tax benefits, the adoption of ASU 2013-11 in January 2014 did not have a material effect on our financial position, results of operations or cash flows.
	Accounting Pronouncements Not Yet Adopted
	In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360) and Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU 2014-08 amends the definition for what types of asset disposals are to be considered discontinued operations, as well as amends the required disclosures for discontinued operations and assets held for sale. ASU 2014-08 also enhances the convergence of the FASB’s and the International Accounting Standard Board’s reporting requirements for discontinued operations. ASU 2014-08 is effective for annual and interim periods beginning on or after December 15, 2014. We do not expect the adoption of ASU 2014-08 to have a material effect on our financial position, results of operations or cash flows.
