	1. Description of Business and Significant Accounting Policies
	Description of Business
	Digimarc Corporation (“Digimarc” or the “Company”), an Oregon corporation, enables governments and enterprises around the world to give digital identities to media and objects that computers can sense and recognize and to which they can react. The Company’s technology provides the means to infuse persistent digital information, “Digimarc IDs,” perceptible only to computers and digital devices, into all forms of media content. The unique digital identifier placed in media generally persists with it regardless of the distribution path and whether it is copied, manipulated or converted to a different format, and does not affect the quality of the content or the enjoyment or other traditional uses of it. The Company’s technology permits computers and digital devices to quickly and reliably identify all forms of media content.
	Interim Consolidated Financial Statements
	The Company has adhered to the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2013 in preparing the accompanying interim consolidated financial statements.
	The accompanying interim consolidated financial statements have been prepared from the Company’s records without audit and, in management’s opinion, include all adjustments (consisting of only normal recurring adjustments) necessary to fairly reflect the financial condition and the results of operations for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”).
	These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013, which was filed with the SEC on February 21, 2014. The results of operations for the interim periods presented in these consolidated financial statements are not necessarily indicative of the results for the full-year.
	Reclassifications
	Certain prior period amounts in the accompanying consolidated financial statements and notes thereto have been reclassified to conform to current period presentation. These reclassifications had no material effect on the results of operations or financial position for any period presented.
	Goodwill
	The Company tests goodwill for impairment annually in June and whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Such reviews assess the fair value of the Company’s assets compared to their carrying value. The Company operates as a single reporting unit. The Company estimates the fair value of its single reporting unit using a market approach, which takes into account the Company’s market capitalization plus an estimated control premium.
	In connection with the Company’s annual impairment test of goodwill as of June 30, 2014 and 2013, it was concluded that there was no impairment as the estimated fair value of the Company’s reporting unit substantially exceeded the carrying value.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU No 2014-09 provides specific guidance to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The amendments in this update permit the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method and is currently assessing the potential impact of this standard on the financial condition or results of operations of the Company.

Fair Value of Financial Instruments	'
	2. Fair Value of Financial Instruments
	The estimated fair values of the Company’s financial instruments, which include cash equivalents, accounts receivable, and accounts payable and other accrued liabilities approximate their carrying values due to the short-term nature of these instruments. The Company records marketable securities at amortized cost, which approximates fair value.
	The Company’s fair value hierarchy for its cash equivalents and marketable securities as of September 30, 2014 and December 31, 2013, respectively, was as follows:
	September 30, 2014		Level 1		Level 2		Level 3		Total

	Other municipals			—		153		—		153
	Total		$	2,343	$	31,253	$	—	$	33,596
	-1	Pre-refunded municipal bonds are collateralized by U.S. treasuries.
	The fair value maturities of the Company’s cash equivalents and marketable securities as of September 30, 2014 are as follows:
			Maturities by Period
			Total		Less than		1-5 years		5-10 years		More than
					1 year						10 years
	Cash equivalents and marketable securities		$	23,233	$	20,282	$	2,951	$	—	$	—
	The Company considers all highly liquid marketable securities with original maturities of 90 days or less at the date of acquisition to be cash equivalents. Cash equivalents include money market funds and certificates of deposit totaling $1,201 and $2,443 at September 30, 2014 and December 31, 2013, respectively. Cash equivalents are carried at cost or amortized cost, which approximates fair value.

	3. Acquisition of Attributor Corporation (“Attributor”)
	The Company accounted for the acquisition of Attributor in December 2012 using the acquisition method of accounting. Under the acquisition method of accounting, the total purchase price was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values.
	The Company recorded a $190 liability in the preliminary purchase price allocation reflecting the estimated fair value of the contingent merger consideration on the acquisition date. At March 31, 2013, the Company determined that the estimated fair value of the contingent merger consideration was $0 based on the Company’s most recent projections and therefore reversed the liability. The reversal of the $190 liability was reflected as a reduction in general and administrative expense within the consolidated statements of operations for the nine-month period ended September 30, 2013. The contingency period ended on December 31, 2013 with $0 contingent merger consideration being earned.

Revenue Recognition	'
	4. Revenue Recognition
	The Company derives its revenue primarily from professional services, consisting of development and consulting services, subscriptions and licensing of its patent portfolio:
		•		Service revenue consists primarily of software development and consulting services. The majority of service revenue arrangements are structured as time and materials consulting agreements.
		•		Subscription revenue includes subscriptions for products and services, is generally recurring, paid in advance and recognized over the term of the subscription.
		•		License revenue, including royalty revenue, originates primarily from licensing the Company’s technology and patents where the Company receives license fees and/or royalties as its income stream.
	Revenue is recognized in accordance with ASC 605 “Revenue Recognition” and ASC 985 “Software” when the following four criteria are met:
		(i)	persuasive evidence of an arrangement exists,
		(ii)	delivery has occurred,
		(iii)	the fee is fixed or determinable, and
		(iv)	collection is reasonably assured.
	Some customer arrangements encompass multiple deliverables, such as patent licenses, professional services, software subscriptions, and maintenance fees. For arrangements that include multiple deliverables, the Company identifies separate units of accounting at inception based on the consensus reached under ASC 605-25 “Multiple-Element Arrangements,” which provides that revenue arrangements with multiple deliverables should be divided into separate units of accounting if certain criteria are met. The Company applies ASC 985 to software deliverables when relevant. The consideration for the arrangement under ASC 605-25 is allocated to the separate units of accounting using the relative selling price method.
	The relative selling price method allocates the consideration based on the Company’s specific assumptions rather than assumptions of a marketplace participant, and any discount in the arrangement proportionally to each deliverable on the basis of each deliverable’s selling price.
	Applicable revenue recognition criteria is considered separately for each separate unit of accounting as follows:
		•		Service revenue is generally determined based on time and materials. Revenue for professional services is recognized as the services are performed. Billing for services rendered generally occurs within one month after the services are provided.
		•		Subscription revenue, which includes subscriptions for products and services, is generally paid in advance and recognized over the term of the subscription, which is generally one month to twenty-four months.
		•		License revenue is recognized when amounts owed to the Company have been earned, are fixed or determinable (within the Company’s normal 30 to 60 day payment terms), and collection is reasonably assured. If the payment terms extend beyond the normal 30 to 60 days, the fee may not be considered to be fixed or determinable, and the revenue would then be recognized when installments are due.
		•		The Company records revenue from certain license agreements upon cash receipt as a result of collectability not being reasonably assured.
		•		The Company’s standard payment terms for license arrangements are 30 to 60 days. Extended payment terms on patent license arrangements are not considered to be fixed or determinable if payments are due beyond the Company’s standard payment terms, primarily because of the risk of substantial modification present in the Company’s patent licensing business. As such, revenue on license arrangements with extended payment terms are recognized as fees become fixed or determinable.
	Deferred revenue consists of billings in advance for professional services, licenses and subscriptions for which revenue has not been earned.

Stock-Based Compensation	'
	6. Stock-Based Compensation
	Stock-based compensation includes expense charges for all stock-based awards to employees and directors. These awards include stock option grants and restricted stock awards.
	Stock-based compensation expense related to internal labor is capitalized to patents and fixed assets based on direct labor hours charged to capitalized patent costs and fixed assets.
	Determining Fair Value
	Stock Options
	Valuation and Amortization Method. The Company estimates the fair value of stock options granted using the Black-Scholes option valuation model. The Company amortizes the fair value of all awards on a straight-line basis over the requisite service periods, which are generally the vesting periods.
	Expected Life. The expected life of awards granted represents the period of time that they are expected to be outstanding. The Company determines the expected life based on historical experience with similar awards, giving consideration to the contractual terms, vesting schedules and pre-vesting and post-vesting forfeitures. Stock options granted generally vest over three to four years for employee grants and one to two years for director grants, and have contractual terms of ten years.
	Expected Volatility. The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of its common stock based on historical prices over the most recent period commensurate with the expected life of the award.
	Risk-Free Interest Rate. The Company determines the risk-free interest rate using current U.S. treasury yields for bonds with a maturity commensurate with the expected life of the award.
	Expected Dividend Yield. The expected dividend yield is derived by the Company’s expected annual dividend rate over the expected term divided by the fair value of the Company’s common stock at the grant date.
	There were no stock options granted during the three- and nine-month periods ended September 30, 2014 and 2013.
	The Company records stock-based compensation expense for stock option awards only for those awards that are expected to vest.
	Restricted Stock
	The fair value of restricted stock awarded is based on the fair market value of the Company’s common stock on the date of the grant (measurement date), and is recognized over the vesting period using the straight-line method.
	The Company records stock-based compensation expense for restricted stock awards only for those awards that are expected to vest.

Earnings Per Common Share	'
	8. Earnings Per Common Share
	The Company calculates basic and diluted earnings per common share in accordance with ASC 260 “Earnings Per Share,” using the two-class method because the Company’s unvested restricted stock is a participating security since these awards contain non-forfeitable rights to receive dividends. Under the two-class method, earnings are allocated to each class of common stock and participating security as if all of the net earnings for the period had been distributed.
	Basic earnings per common share excludes dilution and is calculated by dividing earnings to common shares by the weighted-average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing earnings to common shares by the weighted-average number of common shares, as adjusted for the potentially dilutive effect of stock options. The following table reconciles earnings (loss) per common share for the three- and nine-months ended September 30, 2014 and 2013:

The amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted.
