Initial Public Offering, Policy [Policy Text Block]

Initial Public Offering:

On March 5, 2014, the Company closed its initial public offering (“IPO”) whereby 5,300,436 shares of common stock were sold by the Company to the public (inclusive of 500,436 shares of common stock pursuant to the full exercise of an overallotment option granted to the underwriters). The aggregate net proceeds received by the Company from the offering were approximately $106,071, net of underwriting discounts and commissions and offering expenses payable by the Company. Upon the closing of the IPO, all shares of the Company’s outstanding convertible preferred stock automatically converted into 15,082,141 shares of common stock, and outstanding warrants to purchase convertible preferred stock automatically converted into warrants to purchase 122,572 shares of common stock. On March 13, 2014, all such warrants were exercised, in a net share settlement, resulting in the issuance of 107,217 shares of common stock.

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation:

The accompanying unaudited consolidated interim financial statements have been prepared in accordance with Article 10 of Regulation S-X, “Interim Financial Statements” and the rules and regulations for Form 10-Q of the Securities and Exchange Commission (the “SEC”). Pursuant to those rules and regulations, the Company has condensed or omitted certain information and footnote disclosure it normally includes in its annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”).

In management’s opinion, the Company has made all adjustments (consisting only of normal, recurring adjustments, except as otherwise indicated) necessary to fairly present its consolidated financial position, results of operations and cash flows. The Company’s interim period operating results do not necessarily indicate the results that may be expected for any other interim period or for the full fiscal year. These financial statements and accompanying notes should be read in conjunction with the 2014 consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for its fiscal year ended December 31, 2014 filed with the SEC on February 19, 2015 (the “2014 Form 10-K”). There have been no changes in the significant accounting policies from those that were disclosed in the audited consolidated financial statements for the fiscal year ended December 31, 2014 included in the 2014 Form 10-K.

Derivatives, Policy [Policy Text Block]

Derivative Instruments:

The Company’s primary objective for holding derivative instruments is to reduce its exposure to foreign currency rate changes. The Company reduces its exposure by entering into forward foreign exchange contracts with respect to operating expenses that are forecast to be incurred in currencies other than the U.S. dollar. A majority of the Company’s revenues and a majority of its operating expenditures are transacted in U.S. dollars. However, certain operating expenditures are incurred in or exposed to other currencies, primarily the New Israeli Shekel (“NIS”).

The Company has established forecasted transaction currency risk management programs to protect against fluctuations in fair value and the volatility of future cash flows caused by changes in exchange rates. The Company’s currency risk management program includes forward foreign exchange contracts designated as cash flow hedges. These forward foreign exchange contracts generally mature within 12 months. The Company does not enter into derivative financial instruments for trading purposes.

Derivative instruments measured at fair value and their classification on the consolidated balance sheets are presented in the following table (in thousands):

	Assets as of June 30, 2015 (unaudited)				Liabilities as of December 31, 2014
	Notional Amount		Fair Value		Notional Amount		Fair Value

Foreign exchange forward contract derivatives in cash flow hedging relationships - included in other current assets and accrued expenses and other liabilities	$	16,097	$	610	$	30,662	$	(326	)

For the three and six months ended June 30, 2015, the unaudited consolidated statements of operations reflect a loss of approximately $74 and $598, respectively, related to the effective portion of foreign currency forward contracts. For the three and six months ended June 30, 2014, the unaudited consolidated statements of operations reflect a gain of approximately $18 related to the effective portion of foreign currency forward contracts.

There was no ineffective portion for the three and six months ended June 30, 2015 and 2014.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Issued Accounting Pronouncements:

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”, an updated standard on revenue recognition. ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using IFRS and US GAAP. The core principle of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration (that is, payment) to which the company expects to be entitled in exchange for those goods or services. The new standard also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively (for example, service revenue and contract modifications) and improve guidance for multiple-element arrangements. ASU 2014-09 was initially effective for annual and interim reporting periods beginning after December 15, 2016 and may be adopted either on a full retrospective or modified retrospective approach. On July 9, 2015, the FASB approved a one year deferral of the effective date of the ASU. The revised effective date is for annual reporting periods beginning after December 15, 2017 and interim periods therein, with an early adoption permitted as of the original effective date. The Company is still evaluating the impact of implementation of this standard on its consolidated financial statements.
