Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 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 S-X. 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 property and equipment; • stock-based compensation; • assumptions used in testing for impairment of goodwill; • other long-lived assets; • capitalized software development costs; 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.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

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 that are measured at fair value on a recurring basis (in thousands): September 30, 2015 Level 1 Level 2 Level 3 Total Assets: Cash equivalents Money market mutual funds $ 902 $ — $ — $ 902 Marketable securities Commercial paper — 5,496 — 5,496 Corporate notes and bonds — 54,148 — 54,148 Government obligations — 4,001 — 4,001 U.S. agency obligations — 38,506 — 38,506 — 102,151 — 102,151 Total $ 902 $ 102,151 $ — $ 103,053 December 31, 2014 Level 1 Level 2 Level 3 Total Assets: Cash equivalents Money market mutual funds $ 1,609 $ — $ — $ 1,609 Marketable securities Commercial paper — 2,499 — 2,499 Corporate notes and bonds — 57,105 — 57,105 Government obligations — 1,996 — 1,996 U.S. agency obligations — 38,943 — 38,943 — 100,543 — 100,543 Total $ 1,609 $ 100,543 $ — $ 102,152 We did not have any financial liabilities measured at fair value on a recurring basis at September 30, 2015 or December 31, 2014. We classify our marketable securities as available-for-sale and, accordingly, record them at fair value based on quoted market prices for similar securities. 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 nine months ended September 30, 2015. During the three and nine-month periods ended September 30, 2015 and 2014, we did not record any other-than-temporary impairments. 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 non-recurring 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.

At September 30, 2015, we had $0.7 million of outstanding letters of credit, no revolving loans outstanding under the Loan Agreement and $4.2 million of term loans outstanding at an interest rate of 2.33%.

Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	Note 13. New Accounting Pronouncements Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective. The new standard, as amended, is effective for us on January 1, 2018 with early application effective January 1, 2017 permitted. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting. In April 2015, the FASB issued ASU No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40).” ASU 2015-05 provides guidance regarding the accounting for a customer’s fees paid in a cloud computing arrangement; specifically about whether a cloud computing arrangement includes a software license, and, if so, how to account for the software license. ASU 2015-05 is effective for public companies’ annual periods, including interim periods, beginning after December 15, 2015. Early adoption is permitted. We do not expect the adoption of ASU 2015-05 to have a material effect on our financial position, results of operations or cash flows.
