Summary of Significant Accounting Policies


(a)	Description of Business

KVH Industries, Inc. (together with its subsidiaries, the Company or KVH) designs, develops, manufactures and markets mobile connectivity products and services for the marine and land markets, and inertial navigation products for both the commercial and defense markets. In the fourth quarter of 2016, consistent with certain internal organizational changes implemented, the Company changed its reporting structure from two operating segments based on geographies selling navigation, guidance and stabilization and mobile communication products, to two operating segments based on product lines: mobile connectivity and inertial navigation. The change was driven by several factors including:


•	changes in the Company's overall organizational structure, including the appointment of a Chief Operating Officer and a new Chief Financial Officer;


•	the completion of the Company's planning process for 2017 and later years, as a result of which the Company changed how it will measure and assess its financial performance; and


•	the Company's process for measuring incentive compensation for key executives for 2016 and later years.

KVH’s mobile connectivity products enable customers to receive voice and Internet services, and live digital television via satellite services in marine vessels, recreational vehicles, buses and automobiles. KVH’s CommBox offers a range of tools designed to increase communication efficiency, reduce costs, and manage network operations. KVH sells and leases its mobile connectivity products through an extensive international network of dealers and distributors. KVH also sells and leases products directly to end users.

KVH’s mobile connectivity service sales represent primarily sales earned from satellite voice and Internet airtime services. KVH provides, for monthly fixed and usage fees, satellite connectivity services, including broadband Internet, data and Voice over Internet Protocol (VoIP) services, to its TracPhone V-series customers. Mobile connectivity service sales also include the distribution of commercially licensed entertainment, including news, sports, music, and movies to commercial and leisure customers in the maritime, hotel, and retail markets through KVH Media Group (acquired as Headland Media Limited), the media and entertainment service company that KVH acquired on May 11, 2013, and the distribution of training films and eLearning computer-based training courses to commercial customers in the maritime market through Super Dragon Limited and Videotel Marine Asia Limited (together referred to as Videotel), a maritime training services company that KVH acquired on July 2, 2014. KVH also earns monthly usage fees from third-party satellite connectivity services, including voice, data and Internet services, provided to its Inmarsat and Iridium customers who choose to activate their subscriptions with KVH. Mobile connectivity service sales also include engineering services provided under development contracts, sales from product repairs, and extended warranty sales.

KVH's inertial navigation products offer precision fiber optic gyro (FOG)-based systems that enable platform and optical stabilization, navigation, pointing and guidance. KVH’s inertial navigation products also include tactical navigation systems that provide uninterrupted access to navigation and pointing information in a variety of military vehicles, including tactical trucks and light armored vehicles. KVH’s inertial navigation products are sold directly to U.S. and foreign governments and government contractors, as well as through an international network of authorized independent sales representatives. In addition, KVH's inertial navigation are used in numerous commercial products, such as navigation and positioning systems for various applications including precision mapping, dynamic surveying, autonomous vehicles, train location control and track geometry measurement systems, industrial robotics and optical stabilization.

KVH’s inertial navigation service sales include product repairs, engineering services provided under development contracts and extended warranty sales.


(b)	Principles of Consolidation

The accompanying consolidated financial statements of KVH Industries, Inc. and its wholly owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America. All of the operating expenses of the subsidiaries that serve as the Company’s European, Singaporean, Japanese, and Brazilian international distributors are reflected within sales, marketing, and support within the accompanying consolidated statements of operations. All significant intercompany accounts and transactions have been eliminated in consolidation. As a result of certain acquisitions as discussed in Note 9, “Acquisitions”, the operating results of these acquired entities are included in the Company’s consolidated results of operations from the date of acquisition prospectively. The Company adoption of ASU 2015-02, Consolidation (Topic 810) - Amendments to the Consolidation Analysis, on January 1, 2016 did not have an impact on the entities that the Company consolidates, which represent its wholly-owned subsidiaries, and had no impact on the Company’s consolidated results of operations or financial position.


(c)	Significant Estimates and Assumptions and Other Significant Non-Recurring Transactions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of sales and expenses during the reporting periods. On an on-going basis, the Company evaluates its significant estimates, including those related to revenue recognition, valuation of accounts receivable, value of inventory, valuations and purchase price allocations related to business combinations, expected future cash flows including growth rates, discount rates, terminal values and other assumptions and estimates used to evaluate the recoverability of long-lived assets and goodwill, estimated fair values of long-lived assets, including goodwill, amortization methods and periods, certain accrued expenses and other related charges, stock-based compensation, contingent liabilities, forfeitures and key valuation assumptions for its share-based awards, estimated fulfillment costs for warranty obligations, tax reserves and recoverability of the Company’s net deferred tax assets and related valuation allowance.

Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances.

The Company has accounted for its $35,600 contract received in June 2012 from SANG to purchase TACNAV products and services under ASC 605-25, Multiple-Element Arrangements. See section (e) of this note for estimates and assumptions related to multiple-element-arrangements and completed contract sales accounting.

The SANG total contract value associated with TACNAV products is $21,200, for which final shipments were completed in the second quarter of 2013. Revenue was recognized for these product sales after transfer of title and risk of loss and after inspection occurred. The total contract value associated with all services is $14,400, and services were completed in the third quarter of 2014. The revenue for these services is recognized using the proportional performance accounting method. The Company limits the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations, or subject to customer-specific return or refund privileges. Total revenue recognized on the SANG contract in 2014 was approximately $1,300.

During the fourth quarter of 2016, the Company entered into arrangements with certain third parties who co-produced certain content that the Company distributes where the Company had certain ongoing royalty payments to these third parties. The agreements entered into during the fourth quarter of 2016 settled all outstanding liabilities owed by the Company to these third parties, as well as, resulted in the Company obtaining sole ownership and rights to the applicable content. Based on the final amounts paid under these agreements, the Company recognized a gain in the fourth quarter of 2016 of approximately $855. This amount was recorded as a reduction to sales, marketing and support expense in the Company's consolidated statement of operations for the year ended December 31, 2016.


(d)	Concentration of Credit Risk and Single Source Suppliers

Cash, cash equivalents and marketable securities. The Company is potentially subject to financial instrument concentration of credit risk through its cash, cash equivalent and marketable securities investments. To mitigate these risks the Company maintains cash, cash equivalents and marketable securities with reputable and nationally recognized financial institutions. As of December 31, 2016, $25,712 classified as marketable securities was held by Wells Fargo and substantially all of the cash and cash equivalents were held by Bank of America, N.A. See Note 2 for a description of marketable securities.

Trade accounts receivable. Concentrations of risk (see Note 12) with respect to trade accounts receivable are generally limited due to the large number of customers and their dispersion across several geographic areas. Although the Company does not foresee that credit risk associated with these receivables will deviate from historical experience, repayment is dependent upon the financial stability of those individual customers. The Company establishes allowances for potential bad debts and evaluates, on a monthly basis, the adequacy of those reserves based upon historical experience and its expectations for future collectability concerns. The Company performs ongoing credit evaluations of the financial condition of its customers and generally does not require collateral. Activity within the Company’s allowance for doubtful accounts for the periods presented is as follows:



	2016			2015			2014
Beginning balance	$	3,534		$	2,723		$	1,705
Additions	872			1,342			1,610
Deductions (write-offs/recoveries) from reserve	(929		)	(531		)	(592		)
Ending balance	$	3,477		$	3,534		$	2,723

Certain components from third parties used in the Company’s products are procured from single sources of supply. The failure of a supplier, including a subcontractor, to deliver on schedule could delay or interrupt the Company’s delivery of products and thereby materially adversely affect the Company’s revenues and operating results.


(e)	Revenue Recognition

Product sales. Product sales are recognized when persuasive evidence of an arrangement exists, goods are shipped, title has passed and collectability is reasonably assured. The Company’s standard sales terms require that:


•	All sales are final;


•	Terms are generally Net 30;


•	Shipments are tendered and shipped FOB (or as may be applicable, FCA, or EXW) the Company’s plant or warehouse; and


•	Title and risk of loss or damage passes to the dealer or distributor at the point of shipment when delivery is made to the possession of the carrier.

For certain inertial navigation product sales, customer acceptance or inspection may be required before title and risk of loss transfers. For those sales, revenue is recognized after transfer of title and risk of loss and after notification of customer acceptance. In certain circumstances customers may request a bill and hold arrangement. Under these bill and hold arrangements, revenue is recognized when the Company has fulfilled all of its performance obligations, the units are segregated and available for shipment in accordance with the defined contract delivery schedule, and the Company has received notification of customer acceptance which transfers title and risk of loss to the customer.

Under certain limited conditions, the Company, at its sole discretion, provides for the return of goods. No product is accepted for return and no credit is allowed on any returned product unless the Company has granted and confirmed prior written permission by means of appropriate authorization. The Company establishes reserves for potential sales returns, credits, and allowances, and evaluates, on a monthly basis, the adequacy of those reserves based upon historical experience and expectations for the future.

Multiple-element revenue arrangements. Some of our sales involve multiple-element arrangements that include both hardware-related products and contracted service, or satellite connectivity that are accounted under ASC 605-25, Multiple-Element Arrangements.

Multiple elements, arrangement consideration is allocated to each element based on the relative selling prices of all of the elements in the arrangement using the fair value hierarchy as required by “Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements,” (Accounting Standards Codification “ASC” 605-35). ASC 605-35 requires that the Company establish VSOE of fair value based upon the price charged when the same element is sold separately or established by management having the relevant pricing authority. When VSOE exists it is used to determine the selling price of a deliverable. When VSOE is not established, the Company attempts to establish the selling price of each element based on TPE. When the Company is unable to establish selling price using VSOE or TPE, the Company uses BESP in the allocation of arrangement consideration for the relevant deliverables. The objective of BESP is to determine the price at which the Company would transact a sale if a product or service was sold on a stand-alone basis. The Company determines BESP for our products and certain services by considering multiple factors including, but not limited to, overall market conditions, including geographic or regional-specific market factors and profit objectives for such deliverables.

Each deliverable within the Company's multiple-deliverable revenue arrangements is accounted for as a separate unit of accounting under the guidance of ASC 605-35 if both of the following criteria are met: the delivered item or items have value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. The Company considers a deliverable to have standalone value if the item is sold separately by the Company or another vendor or if the item could be resold by the customer. Further, the Company's revenue arrangements generally do not include a general right of return relative to delivered products.

Deliverables not meeting the criteria for being a separate unit of accounting are combined with a deliverable that does meet that criterion. The appropriate allocation of arrangement consideration and recognition of revenue is then determined for the combined unit of accounting.

Satellite connectivity and media content sales. Directly sold and re-sold satellite connectivity service for voice, data and Internet is recognized monthly based upon minutes or megabytes of traffic processed or contracted fixed fee schedules. Typically, all subscribers enter into a contracted one-year minimum service agreement. The Company has evaluated the factors within ASC 605 regarding gross versus net revenue reporting for its satellite connectivity service sales and its payments to the applicable service providers. Based on the evaluation of the factors within ASC 605, the Company has determined that the applicable indicators of gross revenue reporting were met. The applicable indicators of gross revenue reporting included, but were not limited to, the following:

•

The Company is the primary obligor in its arrangements with its subscribers. The Company manages all interactions with the subscribers, while satellite connectivity service providers do not interact with the subscribers. In addition, the Company assumes the entire performance risk under its arrangements with the subscribers and in the event of a performance issue, the Company may incur reduction in fees without regard for any recourse that the Company may have with the applicable satellite connective service providers.


•	The Company has latitude in establishing pricing, as the pricing under its arrangements with the subscribers is negotiated through a contracting process and has discretion on establishing pricing. The Company then separately negotiates the fees with the applicable satellite service providers.


•	The Company has complete discretion in determining which satellite service providers it will contract with.

As a result, the Company has determined that we earn revenue (as a principal) from the delivery of satellite connectivity services to its subscribers and records all satellite connectivity service sales to subscribers as gross sales. All associated regulatory service fees and costs are recorded net in the consolidated financial statements. Media content sales include the Company's distribution of commercially licensed news, sports, movies and music content for commercial and leisure customers in the maritime, hotel, and retail markets as well as training videos to the merchant marine market that are typically based on a contracted fixed fee schedule. The Company typically recognizes revenue from media content sales ratably over the period of the service contract. The accounting estimates related to the recognition of satellite connectivity and media content service sales in results of operations requires the Company to make assumptions about future billing adjustments for disputes with subscribers as well as unauthorized usage.

Lease financing. Lease financing consists of sales-type leases primarily of the TracPhone V-IP Series. The Company records the leases at a price typically equivalent to normal selling price and in excess of the cost or carrying amount. Upon delivery, the Company records the present value of all payments under these leases as revenues, and the related costs of the product are charged to cost of sales. Interest income is recognized throughout the lease term (typically three to five years) using an implicit interest rate. Through December 31, 2016, lease sales have not been a significant portion of the Company’s total sales.

Contracted service sales. The Company engages in contracts for development, production, and services activities related to standard product modification or enhancement, which it accounts for using the proportional performance method of revenue recognition. The Company considers the nature of these contracts and the types of products and services provided when determining the proper accounting for a particular contract. Customer and government-agency contracted engineering service and grant sales under development contracts are recognized primarily under the proportional performance method during the period in which the Company performs the service or development efforts in accordance with the agreement. Services performed under these types of contracts include engineering studies, surveys, building construction, prototype development, and program management. Performance is determined principally by comparing the accumulated costs incurred to date with management’s estimate of the total cost to complete the contracted work. The Company establishes billing terms at the time project deliverables and milestones are agreed. Unbilled revenue recognized in excess of the amounts invoiced to clients are classified within the accompanying consolidated balance sheets in the caption “prepaid expenses and other assets.”

The use of contract accounting requires significant judgment relative to estimating total contract revenues and costs, including assumptions relative to the length of time to complete the contract, the nature and complexity of the work to be performed, and prices for subcontractor services and materials. The risk to the Company on a fixed-price contract is that if estimates to complete the contract change from one period to the next, profit levels will vary from period to period. The Company's estimates are based upon the professional knowledge and experience of its engineers, program managers and other personnel, who review each long-term contract monthly to assess the contract's schedule, performance, technical matters and estimated cost at completion. Changes in estimates are applied when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods. Any advance payments arising from such extended-term development contracts are recorded as deposits. If, in any period, estimated total costs under a contract indicate an expected loss, then such loss is provided for in that period. Through December 31, 2016, contracted service revenue has not been a significant portion of the Company’s total sales.

Product service sales. Product service sales other than under development contracts are recognized when completed services are provided to the customer and collectability is reasonably assured. The Company establishes reserves for potential sales returns, credit and allowances, and evaluates, on a monthly basis, the adequacy of those reserves based upon historical experience and its expectations for the future. Through December 31, 2016, product service sales have not been a significant portion of the Company’s total sales.

Extended warranty sales. The Company sells extended warranty contracts on mobile connectivity and inertial navigation products. Sales under these contracts are recognized ratably over the contract term. Through December 31, 2016, warranty sales have not been a significant portion of the Company’s total sales.


(f)	Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, which include cash equivalents, investments, accounts receivable, accounts payable and accrued expenses approximate their fair values due to the short maturity of these instruments. The carrying amount of the Company’s mortgage loan approximates fair value based on currently available quoted rates of similarly structured mortgage facilities. See Note 2 for more information on the fair value of the Company’s marketable securities.


(g)	Cash, Cash Equivalents, and Marketable Securities

In accordance with the Company’s investment policy, cash in excess of operational needs is invested in money market mutual funds, government agency bonds, United States treasuries, municipal bonds, corporate notes, and certificates of deposit. All highly liquid investments with a maturity date of three months or less at the date of purchase are classified as cash equivalents. The Company determines the appropriate classification of marketable securities at each balance sheet date. As of December 31, 2016 and 2015, all of the Company’s marketable securities have been designated as available-for-sale and are carried at their fair value with unrealized gains and losses included in accumulated other comprehensive (loss) income in the accompanying consolidated balance sheets.

The Company reviews investments in debt securities for other than temporary impairment whenever the fair value of an investment is less than amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other-than-temporary, the Company considers whether it intends to sell the security, whether it expects to recover the credit loss, and if it is more likely than not that the Company will be required to sell the security prior to recovery. Evidence considered in this assessment includes the reasons for the impairment, compliance with the Company’s investment policy, the severity and duration of the impairment, changes in value subsequent to year-end and forecasted performance of the investee. The Company has reviewed its securities with unrealized losses as of December 31, 2016 and 2015 and has concluded that no other-than-temporary impairments exist.


(h)	Inventories

Inventories are stated at the lower of cost or market using the first-in first-out costing method. The Company adjusted the carrying value of its inventory based on the consideration of excess and obsolete components based on future estimate demand. The Company records inventory charges to costs of product sales.


(i)	Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization are computed on the straight-line method over the estimated useful lives of the respective assets. The principal lives used in determining the depreciation rates of various assets are: buildings and improvements, 5-40 years; leasehold improvements, shorter of original lease term or useful life; machinery, satellite hubs and equipment, and video-on-demand (VOD) units, 4-10 years; office and computer equipment, 3-7 years; and motor vehicles, 5 years.


(j)	Goodwill, Intangible Assets and other Long-Lived Assets

The Company’s goodwill and intangible assets are associated with the purchase of Virtek Communication (now known as KVH Industries Norway AS) in September 2010, Headland Media Limited (now known as the KVH Media Group) in May 2013, and Videotel in July 2014.

Goodwill is recorded when the consideration for an acquisition exceeds the fair value of net tangible and identifiable intangible assets acquired. Goodwill is not amortized, but instead is tested for impairment at least annually, or if events or changes in circumstances indicate that the carrying value may not be recoverable. The Company has not historically incurred any goodwill impairment losses. The Company estimates the fair value of the reporting unit using a discounted cash flow model or other valuation models, such as comparative transactions and market multiples. The impairment test is performed through the application of a two-step process. The first step compares the carrying value of the Company’s reporting units to their estimated fair values as of the test date. If fair value is less than carrying value, a second step is performed to quantify the amount of the impairment, if any. As of August 31, 2016, the Company performed its annual impairment test for goodwill at the reporting unit level and, after conducting the first step, determined that it was not necessary to conduct the second step as it concluded that the fair value of its reporting units exceeded their carrying value. To date, the Company has not had to complete the second step of the goodwill impairment test and therefore has no accumulated goodwill impairment losses. The Company utilized an income approach and market approaches to estimate the fair value of the Company’s reporting units. The Company believes that its assumptions used to estimate the fair value of its reporting units were reasonable. As an additional corroborative test of the reasonableness of those assumptions, the Company completed a reconciliation of its market capitalization and overall enterprise value to the fair value of all of its reporting units as of August 31, 2016. If different assumptions were used, particularly with respect to estimating future cash flows, weighted average costs of capital, and terminal growth rates, different estimates of fair value may have resulted. However, based on the excess of fair value over carrying value and additional sensitivity analysis considered with respect to the Company’s valuation assumptions, the Company concluded it was more-likely-than-not that no goodwill impairment exists. As of August 31, 2016, the Company notes that the fair value of all of the Company’s reporting units exceeded their carrying values by more than 10%. The Company notes that its one reporting unit where the fair value exceeded the carrying value by less than 100% had goodwill of approximately $4,401 at both August 31, 2016 and December 31, 2016. A negative trend of operating results or material changes to forecasted operating results could result in the requirement for additional interim goodwill impairment tests and the potential of a future goodwill impairment charge, which could be material. The Company did not identify any impairment indicators that required an interim goodwill impairment test as of December 31, 2016.

Intangible assets with estimated lives and other long-lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of intangible assets with estimated lives and other long-lived assets is measured by a comparison of the carrying amount of an asset or asset group to future net undiscounted cash flows expected to be generated by the asset or asset group. If these comparisons indicate that an asset is not recoverable, the Company will recognize an impairment loss for the amount by which the carrying value of the asset or asset group exceeds the related estimated fair value. Estimated fair value is based on either discounted future operating cash flows or appraised values, depending on the nature of the asset. During 2016, there were no events or changes in circumstances that indicated any of the carrying amounts of the Company’s intangible assets may not be recoverable. See Note 10 for further discussion of goodwill and intangible assets. During the fourth quarter of 2016, the Company commenced certain facility and other operational improvements. As a result, the Company completed a review of impairment of other long-lived assets for the associated asset groups and a review of the estimated remaining useful lives under ASC 360-10, Impairment and Disposal of Long-Lived Assets, ("ASC 360-10"). Based on the impairment analysis under ASC 360-10, no impairment was noted. The Company did identify certain changes in the remaining estimated useful lives of certain property and equipment and certain components of internally-developed software acquired in the Company’s acquisition of Videotel (see Note 9). The impact of these changes in estimated useful lives resulted in approximately $368 and $188 of additional depreciation and amortization expense, respectively, in the fourth quarter of 2016. The Company notes that the changes in estimated useful lives are not expected to have a material impact to the Company’s future results from operations.


(k)	Other Non-Current Assets

Other non-current assets are primarily comprised of long-term lease receivables, prepaid expenses, and deposits.


(l)	Product Warranty

The Company’s products carry standard limited warranties that range from one to two years and vary by product. The warranty period begins on the date of retail purchase or lease by the original purchaser. The Company accrues estimated product warranty costs at the time of sale and any additional amounts are recorded when such costs are probable and can be reasonably estimated. Factors that affect the Company’s warranty liability include the number of units sold or leased, historical and anticipated rates of warranty repairs and the cost per repair. Warranty and related costs are reflected within sales, marketing and support in the accompanying statements of operations. As of December 31, 2016 and 2015, the Company had accrued product warranty costs of $2,280 and $1,880, respectively. The following table summarizes product warranty activity during 2016 and 2015:



	2016			2015
Beginning balance	$	1,880		$	1,853
Charges to expense	1,723			1,431
Costs incurred	(1,323		)	(1,404		)
Ending balance	$	2,280		$	1,880


(m)	Shipping and Handling Costs

Shipping and handling costs are expensed as incurred and included in cost of sales. Billings for shipping and handling are reflected within net sales in the accompanying statements of operations.


(n)	Research and Development

Expenditures for research and development, including customer-funded research and development, are expensed as incurred. Revenue and related development costs from customer-funded research and development are as follows:



	Year Ended December 31,
	2016		2015		2014
Customer-funded service sales	$	1,400	$	3,002	$	3,806
Customer-funded costs included in costs of service sales	498		1,546		2,633


(o)	Advertising Costs

Costs related to advertising are expensed as incurred. Advertising expense was $2,761, $2,712, and $2,825 for the years ended December 31, 2016, 2015, and 2014, respectively, and is included in sales, marketing, and support expense in the accompanying consolidated statements of operations.


(p)	Foreign Currency Translation

The financial statements of the Company’s foreign subsidiaries located in Denmark and Singapore are maintained using the United States dollar as the functional currency. Exchange rates in effect on the date of the transaction are used to record monetary assets and liabilities. Revenue and other expense elements are recorded at rates that approximate the rates in effect on the transaction dates. Foreign currency exchange gains and losses are recognized within “other (expense) income” in the accompanying consolidated statements of operations. For the years ended December 31, 2016, 2015, and 2014, the Company recorded a total of net foreign currency exchange (gains) losses in its accompanying consolidated statements of operations of $(53), $59, and $126, respectively, which is comprised of both realized and unrealized foreign currency exchange gains and losses.

The financial statements of the Company’s foreign subsidiaries located in the United Kingdom, Brazil, Norway, Cyprus, Belgium, the Netherlands and Japan use the foreign subsidiaries’ respective local currencies as the functional currency. The Company translates the assets and liabilities of these foreign subsidiaries at the exchange rates in effect at year-end. Net sales, costs and expenses are translated using average exchange rates in effect during the year. Gains and losses from foreign currency translation are credited or charged to accumulated other comprehensive loss included in stockholders' equity in the accompanying consolidated balance sheets.


(q)	Income Taxes

Income taxes are accounted for under the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records valuation allowances to reduce deferred income tax assets to the amount that is more likely than not to be realized. The Company determines whether it is more likely than not that a tax position will be sustained upon examination. If it is not more likely than not that a position will be sustained, no amount of the benefit attributable to the position is recognized. The tax benefit to be recognized of any tax position that meets the more likely than not recognition threshold is calculated as the largest amount that is more than 50% likely of being realized upon resolution of the contingency. See Note 8 for further discussion of income taxes.


(r)	Net (Loss) Income per Common Share

Basic net (loss) income per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted net income per share incorporates the dilutive effect of common stock equivalent options, warrants and other convertible securities, if any, as determined in accordance with the treasury stock accounting method. For the year ended December 31, 2016, due to the net loss, the Company excluded all outstanding stock options and non-vested restricted shares from its diluted loss per share calculation as inclusion of these securities would have reduced the net loss per share. Common stock equivalents related to options and restricted stock awards for 766 and 784 shares of common stock for the years ended December 31, 2015, and 2014, respectively, have been excluded from the fully diluted calculation of net income per share, as inclusion would be anti-dilutive.

A reconciliation of the basic and diluted weighted average common shares outstanding is as follows:



	2016	2015	2014
Weighted average common shares outstanding—basic	15,834	15,625	15,420
Dilutive common shares issuable in connection with stock plans	—	209	185
Weighted average common shares outstanding—diluted	15,834	15,834	15,605


(s)	Contingent Liabilities

The Company estimates the amount of potential exposure it may have with respect to claims, assessments and litigation in accordance with ASC 450, Contingencies. As of December 31, 2016, the Company was not party to any lawsuit or proceeding that, in management's opinion, was likely to materially harm the Company's business, results of operations, financial condition or cash flows, as described in Note 17. It is not always possible to predict the outcome of litigation, as it is subject to many uncertainties. Additionally, it is not always possible for management to make meaningful estimate of the potential loss or range of loss associated with such litigation.

As of December 31, 2015, the Company was party to a lawsuit, as described in Note 17. The Company settled the legal claim through a cash payment. The cash payment was included in accrued other in our consolidated balance sheet at December 31, 2015. The cash payment was made in January 2016.


(t)	Operating Segments

The Company operates in two segments, the mobile connectivity and inertial navigation segments. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions regarding resource allocation and assessing performance. The Company’s chief operating decision maker is its President, Chief Executive Officer and Chairman of the Board.

During the fourth quarter of 2016, the Company concluded that it had a change in its operating and reporting segments resulting in two new operating segments, which are also reportable segments and were organized based on products and services. The Company's reportable segments are: mobile connectivity and inertial navigation (see Note 13, "Segment Reporting"). The Company operates in a number of major geographic areas, including internationally. Revenues from international locations, primarily consisting of Canada, European countries, both inside and outside the European Union, as well as Africa, Asia/Pacific, the Middle East, and South America.

(u) Film Production Costs

The Company capitalizes direct costs incurred in the production of its training videos, such as writing, directing, narrating, casting, location rental, and editing. These film costs are classified as a non-current asset on its consolidated balance sheet and are placed into service upon the film title being released and available for customers' use. The Company’s sales model associated with training is subscription-based, in which fees from third parties are not directly attributable to the exhibition of a particular film but relate instead to access to the entire film library. Accordingly, management estimates that the straight line method is the most representative method for the amortization of film costs. Consistent with the period over which revenues are assessed (i.e. the subscription period), the film costs are amortized over four years. In the event that the film title is replaced or removed from the film library before the amortization period has expired, all unamortized costs are expensed immediately.

(v) Recently Issued Accounting Standards

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies. Recently issued standards typically do not require adoption until a future effective date. Prior to their effective date, the Company evaluates the pronouncements to determine the potential effects of adoption on our consolidated financial statements.

Standards Implemented

ASC Update No. 2015-03

In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, and that amortization of debt issuance costs be reported as interest expense. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. This ASU requires retrospective adoption and was effective for us beginning with our first quarterly filing in 2016. The Company had no material capitalized debt issuance costs as of the date of adoption and therefore, there was no material impact to the Company's consolidated financial position as a result of the adoption.

ASC Update No. 2015-05

In April 2015, the FASB issued ASC Update No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. Update No. 2015-05 provides accounting guidance on how customers should treat cloud computing arrangements. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. Update No. 2015-05 is effective for annual reporting periods beginning after December 15, 2015 and interim periods within those reporting periods. The Company elected to adopt the amendments prospectively to all arrangements entered into or materially modified after the effective date. The adoption of Update No. 2015-05 did not have a material impact on the Company’s financial position or results of operations.

ASC Update No. 2015-16

In September 2015, the FASB issued ASC Update No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement - Period Adjustments. Update No. 2015-16 eliminates the requirement to restate prior period financial statements for measurement period adjustments following a business combination. Update No. 2015-16 requires that the cumulative impact of a measurement period adjustment (including the impact on prior periods) be recognized in the reporting period in which the adjustment is identified. The prior period impact of the adjustment should be either presented separately on the face of the income statement or disclosed in the notes. Update No. 2015-16 is effective for fiscal years beginning after December 15, 2015. The adoption of Update No. 2015-16 did not impact the Company’s financial position or results of operations.

ASC Update No. 2015-17

In November 2015, the FASB issued ASC Update No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Update No. 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. It is effective for fiscal years beginning after December 15, 2016; however, earlier application is permitted. The Company elected to early adopt Update No. 2015-17 in 2016 on a prospective basis; as such, prior periods were not retrospectively adjusted. The adoption of Update No. 2015-17 did not have a material impact on the Company’s financial position or results of operations.

ASC Update No. 2017-01

On January 6, 2017, the FASB issued new guidance that changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. This guidance (ASU 2017-01, Business Combinations (Topic 805)-Clarifying the Definition of a Business) is effective for fiscal years beginning after December 15, 2017, including interim periods within those periods. However, early adoption is permitted. If the guidance is early adopted, early application of ASU 2017-01 is allowed for transactions for which the acquisition date occurs before the issuance date or effective date, only when the transaction has not been reported in financial statements that have been issued or made available for issuance. The Company has decided to early adopt Update No. ASU 2017-01 and adopted this guidance for transactions that occur subsequent to October 1, 2016. The adoption of Update No. ASU 2017-01 did not have a material impact on the Company’s financial position or results of operations.

Standards to be Implemented

ASC Updates No. 2014-09, No. 2016-08, No. 2016-10, No. 2016-11 and No. 2016-12

In May 2014, the FASB issued ASC Update No. 2014-09, Revenue from Contracts with Customers (Topic 606). Update No. 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies using International Financial Reporting Standards and U.S. GAAP. The core principle requires entities to recognize revenue in a manner that depicts the transfer of goods or services to customers in amounts that reflect the consideration an entity expects to be entitled to in exchange for those goods or services. In July 2015, the FASB voted to approve a one year deferral, making the standard effective for public entities for annual and interim periods beginning after December 15, 2017.

In March 2016, the FASB issued ASC Update No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). The purpose of Update No. 2016-08 is to clarify the guidance on principal versus agent considerations. It includes indicators that help to determine whether an entity controls the specified good or service before it is transferred to the customer and to assist in determining when the entity satisfied the performance obligation and as such, whether to recognize a gross or a net amount of consideration in their consolidated statement of operations.

In April 2016, the FASB issued ASC Update No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. Update No. 2016-10 clarifies that entities are not required to assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract. Update No. 2016-10 also addresses how to determine whether promised goods or services are separately identifiable and permits entities to make a policy election to treat shipping and handling costs as fulfillment activities. In addition, it clarifies key provisions in Topic 606 related to licensing.

In May 2016, the FASB issued ASC Update No. 2016-11, Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815). Update No. 2016-11 rescinds previous SEC comments that were codified in Topic 605, Topic 932 and Topic 815. Upon adoption of ASC 606, certain SEC comments including guidance on accounting for shipping and handling fees and costs and consideration given by a vendor to a customer should not be relied upon.

In May 2016, the FASB also issued ASC Update No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and Practical Expedients. Update No. 2016-12 provides clarity around collectability, presentation of sales taxes, non-cash consideration, contract modifications at transition and completed contracts at transition. Update No. 2016-12 also includes a technical correction within ASC 606 related to required disclosures if the guidance is applied retrospectively upon adoption.

The Company will adopt Topic 606 effective January 1, 2018. The Company anticipates it will adopt Topic 606 under the modified retrospective method and will only apply this method to contracts that are not completed as of the date of adoption. The modified retrospective method will result in a cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings at the date of initial application for any open contracts as of the adoption date. The Company is currently in the process of reviewing its contracts and related revenue streams to determine the impact that the adoption will have on the Company’s financial position and results of operations.

ASC Update No. 2016-01

In January 2016, the FASB issued ASC Update No. 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. It is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application of certain provisions is permitted. Update No. 2016-01 requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value with changes recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. It also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. Update No. 2016-01 also requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset and liability. The adoption of Update No. 2016-01 is not expected to have a material impact on the Company's financial position or results of operations.

ASC Update No. 2016-02

In February 2016, the FASB issued ASC Update No. 2016-02, Leases (Topic 842). It is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Earlier application is permitted. Update No. 2016-02 is intended to increase the transparency and comparability among organizations by recognizing lease asset and lease liabilities on the balance sheet, including those previously classified as operating leases under current U.S. GAAP, and disclosing key information about leasing arrangements. The Company is in the process of determining the effect that the adoption of this standard will have on its financial position and results of operations.

ASC Update No. 2016-09

In March 2016, the FASB issued ASC Update No. 2016-09, Compensation- Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update is effective for annual reporting periods after December 15, 2016, including interim periods within those fiscal periods. Early adoption is permitted. The purpose of the update is to simplify several areas of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Upon adoption, the impact on our financial position and results of operations will be dependent upon various factors including stock price and timing of option exercises which is difficult to estimate. The Company adopted this ASC update on January 1, 2017. Although, this ASC update does not impact the Company’s results of operations, financial position or cash flows for any periods prior to the adoption, the adoption of this ASC update had the following impact on the date of adoption:

•

The adoption of ASU 2016-09 also requires all income tax adjustments to be recorded in the consolidated statements of operations. The cumulative adjustment upon adoption to accumulated earnings was zero since the increase in net deferred tax assets was fully offset by a corresponding increase in the deferred tax asset valuation allowance. The amount of deferred tax assets that had not been previously recognized due to the recognition of excess tax benefits was

$1,571.


•	The Company has elected to account for forfeitures on share-based payments as these forfeitures occur, which represents a change from the accounting previously required under ASC 718. As a result, the Company notes that future forfeitures could result in a significant reversal of stock-based compensation expense recognized in the period in which such forfeitures occur.

ASC Update No. 2015-11

In April 2015, the FASB issued ASC Update No. 2015-11, Simplifying the Measurement of Inventory regarding ASC Topic 330 - Inventory. Update No. 2015-11 require entities that measure inventory using the first-in, first-out or average cost methods to measure inventory at the lower of cost and net realizable value. Net realizable value is defined as estimated selling price in the ordinary course of business less reasonably predictable costs of completion and disposal. Update No. 2015-11 is effective on a prospective basis for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016, with earlier application permitted. The Company adopted Update No. 2015-11 on January 1, 2017 and the adoption did not have a material effect on the Company's financial position, results of operations or cash flows.

ASC Update No. 2016-13

In June 2016, the FASB issued ASC Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The update is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for fiscal years beginning after December 15, 2018. The purpose of Update No. 2016-13 is to replace the current incurred loss impairment methodology for financial assets measured at amortized cost with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information, including forecasted information, to develop credit loss estimates. The Company is in the process of determining the effect that the adoption will have on its financial position and results of operation.

ASC Update No. 2016-15

In August 2016, the FASB issued ASC Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The purpose of Update No. 2016-15 is to reduce the diversity in practice in presentation and classification of the following items within the statement of cash flows: debt prepayments, settlement of zero coupon debt instruments, contingent consideration payments, insurance proceeds, securitization transactions and distributions from equity method investees. The update also addresses classification of transactions that have characteristics of more than one class of cash flows. The Company is in the process of determining the effect that the adoption will have on its financial position and results of operations.

ASC Update No. 2016-16

In October 2016, the FASB issued ASU Update No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The update is effective for fiscal years beginning after December 15, 2017, including interim reporting periods within those fiscal years. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance. The purpose of Update No. 2016-16 is to allow an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, as opposed to waiting until the asset is sold to an outside party. The Company is in the process of determining the effect that the adoption will have on its financial position and results of operations.

ASC Update No. 2017-04

In January 2017, the FASB issued ASU Update No. 2017-04, Intangibles--Goodwill and Other (Topic 350): Simplifying the Test of Goodwill Impairment. This ASU simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step of the goodwill impairment test under ASC 350. Under previous guidance, if the fair value of a reporting unit is lower than its carrying amount (Step 1), an entity calculates any impairment charge by comparing the implied fair value of goodwill with its carrying amount (Step 2). The implied fair value of goodwill is calculated by deducting the fair value of all assets and liabilities of the reporting unit from the reporting unit’s fair value as determined in Step 1. To determine the implied fair value of goodwill, entities estimate the fair value of any unrecognized intangible assets (including in-process research and development) and any corporate-level assets or liabilities that were included in the determination of the carrying amount and fair value of the reporting unit in Step 1. Under this new guidance if a reporting unit's carrying value exceeds its fair value, an entity will record an impairment charge based on that difference with such impairment charge limited to the amount of goodwill in the reporting unit. This ASU does not change the guidance on completing Step 1 of the goodwill impairment test. An entity will still be able to perform today’s optional qualitative goodwill impairment assessment before determining whether to proceed to Step 1. This ASU will be applied prospectively and is effective for annual and interim impairment test performed in periods beginning after December 15, 2019 for public business enterprises. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company has elected to early adopt this ASU as of January 1, 2017. The adoption of this ASU had no impact on the Company's consolidated statements of operations, financial condition or cash flows. The Company expects that adoption of this ASU will simplify the evaluation and recording of goodwill impairment charges, if any.

There are no other recent accounting pronouncements issued by the FASB that would have a material impact on the Company's financial statements.

Term Note and Line of Credit

On July 1, 2014, the Company entered into (i) a five-year senior credit facility agreement (the Credit Agreement) with Bank of America, N.A., as Administrative Agent, and the lenders named from time to time as parties thereto (the Lenders), for an aggregate amount of up to $80,000, including a revolving credit facility (the Revolver) of up to $15,000 and a term loan (Term Loan) of $65,000 to be used for general corporate purposes, including both (A) the refinancing of the Company’s $30,000 then-outstanding indebtedness under its previous credit facility and (B) permitted acquisitions, (ii) revolving credit notes (together, the Revolving Credit Note) to evidence the Revolver, (iii) term notes (together, the Term Note, and together with the Revolving Credit Note, the Notes) to evidence the Term Loan, (iv) a Security Agreement (the Security Agreement) required by the Lenders with respect to the grant by the Company of a security interest in substantially all of the assets of the Company in order to secure the obligations of the Company under the Credit Agreement and the Notes, and (v) Pledge Agreements (the Pledge Agreements) required by the Lenders with respect to the grant by the Company of a security interest in 65% of the capital stock of each of KVH Industries A/S and KVH Industries U.K. Limited held by the Company in order to secure the obligations of the Company under the Credit Agreement and the Notes.

The Credit Agreement was amended in June 2015 to modify the circumstances under which certain changes in the Company's Board of Directors would constitute a change of control. The Credit Agreement was further amended in September 2015 to modify the Maximum Consolidate Leverage Ratio as of September 30, 2015. The Credit Agreement was amended again in March 2017 to further modify the Maximum Consolidated Leverage Ratio, to amend the Applicable Rate and amortization schedule of the Term Loan and to modify the definition of Consolidated Fixed Charges, as well as make certain other changes.

The $65,000 Term Note was executed on July 1, 2014 in connection with the acquisition of Videotel. See Note 13 below for more information regarding the acquisition. Proceeds in the amount of $35,000 were applied toward the payment of a portion of the purchase price for the acquired shares of Videotel, and proceeds in the amount of approximately $30,000 were applied toward the refinancing of the then-outstanding balance of the Company’s previous credit facility. The Company was required to make principal repayments on the Term Loan in the amount of approximately $1,200 at the end of each of the first 8 three-month periods following the closing; thereafter, the Company was required to make principal repayments in the amount of approximately $1,600 for each succeeding three-month period until the maturity of the loan on July 1, 2019. The Company made the first payment on this debt in September 2014 and has made all required principal repayments on a timely basis. In connection with the March 2017 amendment, the Company made an additional principal repayment of $6,000 on the Term Note and amended the repayment terms. Under the amended terms, the Company must make principal repayments of $575 every three months starting on April 1, 2017 until the Term Note maturity on July 1, 2019. On the maturity date, the entire remaining principal balance of the loan, including any future loans under the Revolver, is due and payable, together with all accrued and unpaid interest, penalties, and other amounts due and payable under the Credit Agreement. The Credit Agreement contains provisions requiring the mandatory prepayment of amounts outstanding under the Term Loan and the Revolver under specified circumstances, including (i) 100% of the net cash proceeds from certain dispositions to the extent not reinvested in the Company’s business within a stated period, (ii) 50% of the net cash proceeds from stated equity issuances and (iii) 100% of the net cash proceeds from certain receipts of more than $250 outside the ordinary course of business. The prepayments are first applied to the Term Loan, in inverse order of maturity, and then to the Revolver. In the discretion of the Administrative Agent, certain mandatory prepayments made on the Revolver can permanently reduce the amount of credit available under the Revolver.

Loans under the Credit Agreement bear interest at varying rates determined in accordance with the Credit Agreement. Each LIBOR Rate Loan, as defined in the Credit Agreement, bears interest on the outstanding principal amount thereof for each interest period from the applicable borrowing date at a rate per annum equal to the LIBOR Daily Floating Rate or LIBOR Monthly Floating Rate, each as defined in the Credit Agreement, as applicable, plus the Applicable Rate, as defined in the Credit Agreement, and each Base Rate Loan, as defined in the Credit Agreement, bears interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the Base Rate, as defined in the Credit Agreement, plus the Applicable Rate. The Applicable Rate ranges from 1.75% to 2.25%, depending on the Company’s Consolidated Leverage Ratio, as defined in the Credit Agreement. The highest Applicable Rate applies when the Consolidated Leverage Ratio exceeds 1.50:1.00. Upon certain defaults, including failure to make payments when due, interest becomes payable at a higher default rate.

Borrowings under the Revolver are subject to the satisfaction of numerous conditions precedent at the time of each borrowing, including the continued accuracy of the Company’s representations and warranties and the absence of any default under the Credit Agreement. As of December 31, 2016, there were no borrowings outstanding under the revolver and the full balance of $15,000 was available for borrowing.

The Credit Agreement contains two financial covenants, a Maximum Consolidated Leverage Ratio and a Minimum Consolidated Fixed Charge Coverage Ratio, each as defined in the Credit Agreement. In September 2015, the Maximum Consolidated Leverage Ratio was increased from 1.00:1.00 to 1.75:1.00 for September 30, 2015, 1.50:1.00 for December 31, 2015, and 1.25:1.00 for March 31, 2016 and each fiscal quarter thereafter. The Minimum Consolidated Fixed Charge Coverage Ratio may not be less than 1.25:1.00. The Company was in compliance with these financial ratio debt covenants as of December 31, 2016. As a result of the March 2017 amendment, the Maximum Consolidated Leverage Ratio was increased to 1.50:1.00. In addition, the definition of the Consolidated Fixed Charge Coverage Ratio was amended to include only maintenance capital expenditures as defined.

The Credit Agreement imposes certain other affirmative and negative covenants, including without limitation covenants with respect to the payment of taxes and other obligations, compliance with laws, entry into material contracts, creation of liens, incurrence of indebtedness, investments, dispositions, fundamental changes, restricted payments, changes in the nature of the Company’s business, transactions with affiliates, corporate and accounting changes, and sale and leaseback arrangements.

The Company’s obligation to repay loans under the Credit Agreement could be accelerated upon a default or event of default under the terms of the Credit Agreement, including certain failures to pay principal or interest when due, certain breaches of representations and warranties, the failure to comply with the Company’s affirmative and negative covenants under the Credit Agreement, a change of control of the Company, certain defaults in payment relating to other indebtedness, the acceleration of payment of certain other indebtedness, certain events relating to the liquidation, dissolution, bankruptcy, insolvency or receivership of the Company, the entry of certain judgments against the Company, certain events relating to the impairment of collateral or the Lenders' security interest therein, and any other material adverse change with respect to the Company.

Mortgage Loan

On April 6, 2009, the Company entered into a mortgage loan in the amount of $4,000 related to its headquarters facility in Middletown, Rhode Island. On June 9, 2011, the Company entered into an amendment to the mortgage loan. The loan term is ten years, with a principal amortization of 20 years, and the interest rate will be a rate per year adjusted periodically based on a defined interest period equal to the BBA LIBOR Rate of 2.18% plus 2.00 percentage points. Land, building and improvements with an approximate carrying value of $5,000 as of December 31, 2016 secure the mortgage loan. The monthly mortgage payment is approximately $14 plus interest and increases in increments of approximately $1 each year throughout the life of the mortgage. Due to the difference in the term of the loan and amortization of the principal, a balloon payment of $2,551 is due on April 1, 2019. The loan contains one financial covenant, a Fixed Charge Coverage Ratio, which applies in the event that the Company’s consolidated cash, cash equivalents, and marketable securities balance falls below $25,000 at any time. As the Company’s consolidated cash, cash equivalents, and marketable securities balance was above the minimum threshold throughout the year ended December 31, 2016, the Fixed Charge Coverage Ratio did not apply. Under the mortgage loan, the Company may prepay its outstanding loan balance subject to certain early termination charges as defined in the mortgage loan agreement. If the Company were to default on its mortgage loan, the land, building and improvements would be used as collateral. As discussed in Note 16 to the consolidated financial statements, effective April 1, 2010, in order to reduce the volatility of cash outflows that arise from changes in interest rates, the Company entered into two interest rate swap agreements that are intended to hedge its mortgage interest obligations by fixing the interest rates specified in the mortgage loan to 5.91% for half of the principal amount outstanding and 6.07% for the remaining half of the principal amount outstanding as of April 1, 2010 until the mortgage loan expires on April 16, 2019.

Equipment Loan

On January 30, 2013, the Company borrowed $4,700 from a bank and pledged as collateral six satellite hubs and related equipment, including three hubs purchased in 2012. The term of the equipment loan is five years, and the loan bears interest at a fixed rate of 2.76% per annum. The monthly payment is approximately $83, including interest expense. On December 30, 2013, the Company borrowed $1,200 from a bank and pledged as collateral one satellite hub and related equipment. The term of the equipment loan is five years, and the loan bears interest at a fixed rate of 3.08% per annum. The monthly payment is approximately $21, including interest expense.

The following is a summary of future principal payments under these long-term debt agreements:



Year ending December 31,	Principal Payment
2017	$	7,900
2018	6,931
2019	43,222
Total outstanding at December 31, 2016	$	58,053

Stockholders’ Equity


(a)	Employee Stock Options

On June 15, 2016, at the Company's 2016 Annual Meeting of Stockholders, the stockholders of the Company approved the 2016 Equity and Incentive Plan (2016 Plan). The 2016 Plan authorizes the Company to issue up to 3,000 shares of common stock (plus an additional 1,690 shares intended to roll over into the 2016 Plan shares subject to awards outstanding on June 15, 2016 under earlier plans that may be forfeited, canceled, reacquired by the Company or terminated) pursuant to stock options, restricted stock awards and other stock-based awards.

Options are generally granted with an exercise price equal to the fair market value of the common stock on the date of grant and generally vest in equal annual amounts over four years beginning on the first anniversary of the date of the grant. No options are exercisable for periods of more than five years after date of grant. Under the 2016 Plan, each share issued under awards other than options and stock appreciation rights will reduce the number of shares reserved for issuance by two shares. Shares issued under options or stock appreciation rights will reduce the shares reserved for issuance on a share-for-share basis. The 2016 Plan and earlier equity compensation plans, pursuant to which 12,415 shares of the Company’s common stock were reserved for issuance, were all approved by the Company's shareholders. As of December 31, 2016, 2,895 shares were available for future grants. The Compensation Committee of the Board of Directors administers the equity compensation plans, approves the individuals to whom awards will be granted and determines the number of shares and other terms of each award. Outstanding options under the Company's equity compensation plans at December 31, 2016 expire from February 2017 through November 2021. None of the Company’s outstanding options includes performance-based or market-based vesting conditions as of December 31, 2016.

The Company has estimated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model. The expected volatility assumption is based on the historical daily price data of the Company’s common stock over a period equivalent to the weighted average expected life of the Company’s options. The expected term of options granted is derived using assumed exercise rates based on historical exercise patterns and represents the period of time the options granted are expected to be outstanding. The risk-free interest rate is based on the actual U.S. Treasury zero-coupon rates for bonds matching the expected term of the option as of the option grant date. The dividend yield of zero is based upon the fact that the Company has not historically declared or paid cash dividends, and does not expect to declare or pay dividends in the foreseeable future.

The per share weighted-average fair values of stock options granted during 2016, 2015, and 2014 were $2.77, $4.39, and $4.71, respectively. The weighted-average assumptions used to value options as of their grant date were as follows:



	Year Ended December 31,
	2016		2015		2014
Risk-free interest rate	1.43	%	1.55	%	1.52	%
Expected volatility	38.2	%	43.3	%	46.5	%
Expected life (in years)	4.18		4.17		4.21
Forfeiture rate	5.00	%	5.00	%	5.00	%
Dividend yield	0	%	0	%	0	%

The changes in outstanding stock options for the year ended December 31, 2016 are as follows:



	Number of Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in Years)	Aggregate Intrinsic Value
Outstanding at December 31, 2015	1,177		$	11.60
Granted	75		$	8.90
Exercised	(269	)	$	9.06
Expired, canceled or forfeited	(297	)	$	13.68
Outstanding at December 31, 2016	686		$	11.41	2.23	$	681
Exercisable at December 31, 2016	379		$	11.39	1.50	$	382
Options vested or expected to vest at December 31, 2016	674		$	11.42	2.04	$	662

The total aggregate intrinsic value of options exercised was $484, $50, and $232 in 2016, 2015, and 2014, respectively. The total aggregate intrinsic value of options outstanding at December 31, 2015 and 2014 was $123 and $1,814, respectively. The total aggregate intrinsic value of options exercisable at December 31, 2015 and 2014 was $122 and $761, respectively.

As of December 31, 2015 and 2014, the number of options exercisable was 687 and 490, respectively, and the weighted average exercise price of those options was $11.60 and $11.87 per share, respectively. The weighted average remaining contractual term for options exercisable at December 31, 2015 and 2014 was 2.00 and 1.76 years, respectively. The weighted average remaining contractual term for options outstanding at December 31, 2015 and 2014 was 2.04 and 2.72 years, respectively.

As of December 31, 2016, there was $790 of total unrecognized compensation expense related to stock options, which is expected to be recognized over a weighted-average period of 1.94 years. In 2016, 2015, and 2014, the Company recorded compensation charges of $702, $1,229, and $1,368, respectively, related to stock options. Compensation costs for options subject only to service conditions that vest ratably are recognized on a straight-line basis over the requisite service period for the entire award. During 2016, 2015, and 2014, cash received under stock option plans for exercises was $2,438, $90 and $471, respectively.


(b)	Restricted Stock

The Company granted 424, 203, and 265 restricted stock awards to employees under the terms of the 2016 Plan or the Amended and Restated 2006 Stock Incentive Plan (2006 Plan) for the years ended December 31, 2016, 2015, and 2014, respectively. The restricted stock awards generally vest annually over four years from the date of grant subject to the recipient remaining an employee through the applicable vesting dates. Compensation expense for restricted stock awards is measured at fair value on the date of grant based on the number of shares granted and the quoted market closing price of the Company’s common stock. Such value is recognized as expense over the vesting period of the award, net of estimated forfeitures. The weighted-average grant-date fair value of restricted stock granted during 2016, 2015, and 2014 was $8.68, $12.43, and $13.57 per share, respectively.

As of December 31, 2016, there was $4,344 of total unrecognized compensation expense related to restricted stock awards, which is expected to be recognized over a weighted-average period of 2.32 years. Compensation costs for awards subject only to service conditions that vest ratably are recognized on a straight-line basis over the requisite service period for the entire award. Compensation cost for awards initially subject to certain performance conditions are recognized on a ratable basis over the requisite service period for the entire award. In 2016, 2015, and 2014, the Company recorded compensation charges of $2,938, $2,422, and $2,317, respectively, related to restricted stock awards.

Restricted stock activity under the 2006 Plan and the 2016 Plan for 2016 is as follows:



	Number of Shares		Weighted- average grant date fair value
Outstanding at December 31, 2015, unvested	458		$	13.22
Granted	424		8.68
Vested	(186	)	12.82
Forfeited	(52	)	10.39
Outstanding at December 31, 2016, unvested	644		$	10.58


(c)	Employee Stock Purchase Plan

On June 15, 2016, at the Company's 2016 Annual Meeting of Stockholders, the stockholders of the Company also approved amendments to the Company's Amended and Restated 1996 Employee Stock Purchase Plan (ESPP) that, among other things, increased the number of shares of common stock reserved for issuance by 1,000 to a total of 1,650, of which 1,000 shares remain available as of December 31, 2016.

The ESPP covers all of the Company’s employees. Under the terms of the ESPP, eligible employees can elect to have up to six percent of their pre-tax compensation withheld to purchase shares of the Company’s common stock on a semi-annual basis. Before the amendment to the plan, the ESPP allowed eligible employees the right to purchase the Company’s common stock on a semi-annual basis at 85% of the market price at the end of each purchase period. Under the amendment, the ESPP now allows eligible employees the right to purchase the Company's common stock on a semi-annual basis at 85% of the market price on the first or last day of each purchase period, whichever is lower. During 2016, 2015, and 2014, shares issued under this plan were 18, 28, and 12 shares, respectively. The Company utilizes the Black-Scholes option-pricing model to calculate the fair value of these discounted purchases. The fair value of the 15% discount is recognized as compensation expense over the purchase period. The Company applies a graded vesting approach because the ESPP provides for multiple purchase periods and is, in substance, a series of linked awards. In 2016, 2015, and 2014, the Company recorded compensation charges of $11, $58, and $55, respectively, related to the ESPP. During 2016, 2015, and 2014, cash received under the ESPP was $146, $291, and $138, respectively.

As of December 31, 2016, the Company had federal research and development tax credit carry-forwards in the amount of $3,875 and other general business credits of $9 that expire in years 2026 through 2036. The Company also had alternative minimum tax credits of $54 that have no expiration date. As of December 31, 2016, the Company had state research and development tax credit carry-forwards in the amount of $3,529 that expire in years 2016 through 2023. The Company also had other state tax credit carry-forwards of $241 available to reduce future state tax expense that expire in years 2018 through 2019. The tax benefit related to $1,571 of federal and state tax credits would result in a credit to additional paid-in capital when these deferred tax assets reduce taxes payable.

The Company’s ability to utilize these net operating loss carry-forwards and tax credit carry-forwards may be limited in the future if the Company experiences an ownership change pursuant to Internal Revenue Code Section 382. An ownership change occurs when the ownership percentages of 5% or greater stockholders change by more than 50% over a three-year period.

In assessing the reliability of its net deferred tax assets, the Company considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. As of December 31, 2016, the Company concluded that a net increase of $6,879 of the valuation allowance was appropriate. As part of the Company’s analysis, the Company evaluated, among other factors, its recent history of generating taxable income and its near-term forecasts of future taxable income. The net increase in valuation allowance of $6,879 is composed of expense of $7,425, a decrease of $287 related to the expiration of previously reserved state tax credit carry-forwards, and a decrease of $258 related to the use of net operating loss and credit carryforwards attributed to tax deductions in excess of recognized compensation expense from employee stock compensation awards that existed as of the adoption of ASC 718, Compensation - Stock Compensation. Approximately $454 of the valuation allowance is attributable to tax deductions in excess of recognized compensation cost from employee stock compensation awards that existed as of the adoption of ASC 718. The Company will recognize the net deferred tax asset and corresponding benefit to additional paid-in capital for these windfall tax benefits once such amounts reduce income taxes payable, in accordance with the requirements of ASC 718.

As of December 31, 2016, the Company has not provided for U.S. deferred income taxes on undistributed earnings of its foreign subsidiaries of approximately $14,543 since these earnings are expected to be indefinitely reinvested. Upon distribution of those earnings in the form of dividends or otherwise, the Company will be subject to additional U.S. and state income taxes (less foreign tax credits), as well as withholding taxes in its foreign locations. The amount of taxes attributable to the undistributed earnings is not practicably determinable.

The Company establishes reserves for uncertain tax positions based on management’s assessment of exposure associated with tax deductions, permanent tax differences, and tax credits. The tax reserves are analyzed periodically and adjustments are made as events occur to warrant adjustment to the reserve. The Company's policy is to recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense.

During the years ended December 31, 2016, 2015, and 2014, the aggregate changes in the total gross amount of unrecognized tax benefits are summarized as follows:



	Year Ended December 31,
	2016			2015			2014
Unrecognized tax benefits as of January 1	$	983		$	2,487		$	—
Gross increase in unrecognized tax benefits - prior year tax positions	—			168			—
Gross decrease in unrecognized tax benefits due to currency fluctuations - prior year tax positions	(131		)	(116		)	—
Gross increase in unrecognized tax benefits - current year tax position	293			13			14
Settlements with taxing authorities	(330		)	(1,569		)	—
Lapse of statute of limitations	—			—			—
Positions assumed in Videotel transaction	—			—			2,473
Ending balance	$	815		$	983		$	2,487

The Company had gross unrecognized tax benefits of $815, $983, and $2,487 as of December 31, 2016, 2015, and 2014, respectively. $815, $983, and $1,172 represent the amount of unrecognized tax benefits that, if recognized, would result in a reduction of the Company's effective tax rate at December 31, 2016, 2015, and 2014, respectively.

The Company recorded interest and penalties of $40, $78, and $84 in its statement of operations for the years ended December 31, 2016, 2015, and 2014, respectively. The combined amount of accrued interest and penalties related to tax positions taken on our tax returns and included in non-current income taxes payable was approximately $545, $468, and $1,067 as of December 31, 2016, 2015, and 2014, respectively.

The timing of any resolution of income tax examinations is highly uncertain, as are the amounts and timing of any settlement payment. These events could cause fluctuations in the balance sheet classification of current and non-current assets and liabilities. The Company does not expect a reduction of unrecognized tax benefits within the next twelve months.

The Company’s tax jurisdictions include the United States, the UK, Denmark, Cyprus, Norway, Brazil, Singapore, Belgium, Bermuda, the Netherlands, Hong Kong, Japan, and India. In general, the statute of limitations with respect to the Company's United States federal income taxes has expired for years prior to 2013, and the relevant state and foreign statutes vary. However, preceding years remain open to examination by United States federal and state and foreign taxing authorities to the extent of future utilization of net operating losses and research and development tax credits generated in each preceding year.

Acquisition

Business Combinations [Abstract]

Acquisition

On July 2, 2014, KVH Media Group Limited (KMG UK), an indirectly wholly owned subsidiary of KVH, entered into a Share Purchase Agreement with Nigel Cleave to acquire all of the issued share capital of Super Dragon Limited and Videotel Marine Asia Limited, for an aggregate purchase price of approximately $47,446, which excluded $1,719 of cash consideration that was considered deferred compensation in purchase accounting. The Company expensed approximately $358 and $770 related to the deferred compensation during the year ended December 31, 2016 and 2015, respectively. Videotel is a maritime training services company headquartered in London that produces and distributes training films and eLearning computer-based training courses to commercial customers in the maritime market. Videotel also has sales offices in Hong Kong and Singapore. The purchase price was determined through arm’s-length negotiation and was subject to a potential post-closing adjustment based on the value of the net assets delivered at the closing. In the second quarter of 2015, the Company finalized its valuations of the fair value of the assets acquired and liabilities assumed, which resulted in no adjustments to the purchase price.

The Share Purchase Agreement contains certain representations, warranties, covenants and indemnification provisions. The Share Purchase Agreement provides that 10% of the purchase price would be held in escrow for a period of approximately 21 months after the closing in order to satisfy valid indemnification claims that KMG UK may assert for specified breaches of representations, warranties and covenants. The escrow and holdback amounts of approximately $6,000 were fully funded during the first quarter of 2015. In April 2016, approximately $600 of the $4,400 total escrow funds were released to the Company to cover post-completion accounts receivable write-offs and the balance was released to the seller. The holdback of approximately $1,600 was released to the seller in July 2016.

In the Share Purchase Agreement, Mr. Cleave agreed to comply with certain confidentiality, non-competition and non-solicitation covenants with respect to the business of Videotel for a period of 18 months after the closing.

The total purchase price and the excess of the total purchase price over the estimated fair value of the net assets acquired are as follows:



Consideration transferred - cash			$	47,446
Book value of tangible net assets acquired	$	1,732
Fair value adjustments to deferred revenue	961
Fair value of tangible net assets acquired			$	2,693

Identifiable intangibles at acquisition-date fair value
Subscriber relationships	$	12,759
Proprietary content	9,814
Internally developed software	2,160
Favorable operating leases	791
Total intangible assets			$	25,524
Deferred income taxes			(3,922		)
Goodwill			$	23,151

The acquired finite-lived intangible assets from the Videotel acquisition were recorded at their estimated fair value of $25,524 on the acquisition date. Refer to Note 1 and Note 10 for the classification of Videotel intangible assets including their useful lives.

From the acquisition on July 2, 2014 through December 31, 2016, the Company has recorded approximately $55,100 of service revenues attributable to Videotel within its consolidated financial statements, of which approximately $21,500 was recorded during the year ended December 31, 2016. Transaction costs related to the acquisition of Videotel were $1,200 for the year ended December 31, 2014.

The following table summarizes the supplemental statements of operations information on an unaudited pro forma basis as if the Videotel acquisition had occurred on January 1, 2013:



	Year Ended December 31,
	2014
Pro forma net revenues	$	183,886
Pro forma net income	$	2,386
Basic pro forma net income per share	$	0.15
Diluted pro forma net income per share	$	0.15

The pro forma results presented above are for illustrative purposes only for the periods presented and do not purport to be indicative of the actual results which would have occurred had the transaction been completed as of the beginning of the period, nor are they indicative of results of operations which may occur in the future.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Segment Reporting [Abstract]

Segment Reporting

During the fourth quarter of 2016, the Company had a change in its operating and reportable segments. This change was a result of the following:


•	Changes in overall organizational structure, including appointments of a Chief Operating Officer and a new Chief Financial Officer


•	Changes in how financial performance is measured and assessed based on current operating results and planned future operations driven by completion of the Company’s fiscal 2017 and long-term planning process


•	Consideration regarding how incentive compensation for key executives will be measured for both 2016 and prospectively.

Therefore, in the fourth quarter of 2016, the Company concluded that it has two new operating segments, which are also reportable segments, and were organized based on products and services. The Company’s reportable segments are:


•	Mobile connectivity, and


•	Inertial navigation

The Company’s Chief Operating Decision Maker (CODM), whom the Company has identified as its Chief Executive Officer, primarily evaluates the business and assesses performance based on the revenue and operating income of the segments. The Company does not allocate interest, taxes, and certain corporate-level costs to its reportable segments, as discussed further below.

The financial results of each segment are based on revenues from external customers, cost of revenue and operating expenses that are directly attributable to the segment and an allocation of costs from shared functions. These shared functions include, but are not limited to, facilities, human resources, information technology, and engineering. Allocations are made based on management’s judgment of the most relevant factors, such as head count, number of customer sites, or other operational data that contributes to the shared costs. Certain corporate-level costs have not been allocated as they are not attributable to either segment. These costs primarily consist of broad corporate functions, including executive, legal, finance, and costs associated with corporate actions. Segment-level asset information has not been provided as such information is not reviewed by the CODM for purposes of assessing segment performance and allocating resources. There are no inter-segment sales or transactions.

The Company's performance is impacted by the levels of activity in the marine and land mobile markets and defense sectors, among others. Performance in any particular period could be impacted by the timing of sales to certain large customers.

The mobile connectivity segment primarily manufactures and distributes a comprehensive family of mobile satellite antenna products and services that provide access to television, the Internet and voice services while on the move. Product sales within the mobile connectivity segment accounted for approximately 23%, 23% and 25% of our consolidated net sales for 2016, 2015 and 2014, respectively. Sales of mini-VSAT Broadband airtime service accounted for approximately 37%, 35%, and 35% of our consolidated net sales for 2016, 2015, 2014, respectively. Sales of content and training sales within the mobile connectivity segment accounted for approximately 20%, 21% and 14% of our consolidated net sales for 2016, 2015 and 2014, respectively.

The inertial navigation segment manufactures and distributes a portfolio of digital compass and fiber optic gyro (FOG)-based systems that address the rigorous requirements of military and commercial customers and provide reliable, easy-to-use and continuously available navigation and pointing data. The principal product categories in this segment include the FOG based inertial measurement units (IMUs) for precision guidance, FOGs for tactical navigation as well as pointing and stabilization systems, and digital compasses that provide accurate heading information for demanding applications, security, automation and access control equipment and systems. Sales of FOG-based guidance and navigation systems within the inertial navigation segment accounted for approximately 10%, 10%, and 12% of consolidated net sales for 2016, 2015, and 2014, respectively. Sales of tactical guidance and navigation systems within the inertial navigation segment accounted for approximately 8%, 8%, and 11% of consolidated net sales for 2016, 2015, and 2014, respectively.

No other single product class accounts for 10% or more of consolidated net sales.

The Company operates in a number of major geographic areas, including internationally. Revenues from international locations, primarily consisting of Canada, European countries, both inside and outside the European Union, as well as Africa, Asia/Pacific, the Middle East, and India. Revenues are based upon customer location and internationally represented 63%, 67%, and 58% of consolidated net sales for 2016, 2015 and 2014, respectively. Sales to Canada represented 11% and 10% of net sales for 2016 and 2015, respectively. No other individual foreign country represented 10% or more of the Company’s consolidated net sales for 2016 or 2015, respectively. No individual foreign country represented 10% or more of the Company's consolidated net sales for 2014.

As of December 31, 2016 and 2015, the long-lived tangible assets related to the Company’s international subsidiaries were less than 10% of the Company’s long-lived tangible assets and were deemed not material.

Net sales and operating earnings (loss) for the Company's reporting segments and the Company's loss (income) before benefit from income taxes for the years ended December 31, 2016, 2015, and 2014 were as follows:

Share Buyback Program	12 Months Ended
Share Buyback Program	Dec. 31, 2016
Disclosure of Repurchase Agreements [Abstract]
Share Buyback Program	Share Buyback Program On November 26, 2008, the Company’s Board of Directors authorized a program to repurchase up to 1,000 shares of the Company’s common stock. As of December 31, 2016, 341 shares of the Company’s common stock remain available for repurchase under the authorized program. The repurchase program is funded using the Company’s existing cash, cash equivalents, marketable securities and future cash flows. Under the repurchase program, the Company, at management’s discretion, may repurchase shares on the open market from time to time, in privately negotiated transactions or block transactions, or through an accelerated repurchase agreement. The timing of such repurchases depends on availability of shares, price, market conditions, alternative uses of capital, and applicable regulatory requirements. The program may be modified, suspended or terminated at any time without prior notice. The repurchase program has no expiration date. There were no other repurchase programs outstanding during the year ended December 31, 2016 and no repurchase programs expired during the period. During the years ended December 31, 2016, 2015, and 2014, the Company did not repurchase any shares of its common stock in open market transactions.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

ASC 820, Fair Value Measurements and Disclosures, provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. ASC 820 describes three levels of inputs that may be used to measure fair value:


Level 1:	Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. The Company’s Level 1 assets are investments in money market mutual funds, United States treasuries, and certificates of deposit.


Level 2:	Quoted prices for similar assets or liabilities in active markets; or observable prices that are based on observable market data, based on directly or indirectly market-corroborated inputs. The Company’s Level 2 assets are investments in certain corporate notes and its Level 2 liabilities are interest rate swaps.


Level 3:	Unobservable inputs that are supported by little or no market activity, and are developed based on the best information available given the circumstances. The Company has no Level 3 assets.

Assets and liabilities measured at fair value are based the valuation techniques identified in the table below. The valuation techniques are:


(a)	Market approach—prices and other relevant information generated by market transactions involving identical or comparable assets.

(b)

The valuations of the interest rate swaps intended to mitigate the Company’s interest rate risk are determined with the assistance of a third-party financial institution using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each instrument. This analysis utilizes observable market-based inputs, including interest rate curves and interest rate volatility, and reflects the contractual terms of these instruments, including the period to maturity.

The following tables present financial assets and liabilities at December 31, 2016 and December 31, 2015 for which the Company measures fair value on a recurring basis, by level, within the fair value hierarchy:



December 31, 2016	Total		Level 1		Level 2		Level 3		Valuation Technique
Assets
Money market mutual funds	$	21,848	$	21,848	$	—	$	—	(a)
Certificates of deposit	3,864		3,864		—		—		(a)
Liabilities
Interest rate swaps	$	158	$	—	$	158	$	—	(b)
December 31, 2015	Total		Level 1		Level 2		Level 3		Valuation Technique

Certificates of deposit	6,089		6,089		—		—		(a)
Liabilities
Interest rate swaps	$	238	$	—	$	238	$	—	(b)

Certain financial instruments are carried at cost on the consolidated balance sheets, which approximates fair value due to their short-term, highly liquid nature. These instruments include cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses.

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company's non-financial assets, such as goodwill, intangible assets, and other long-lived assets resulting from business combinations, are measured at fair value using income approach valuation methodologies at the date of acquisition and subsequently re-measured if an impairment exists. There were no impairments of the Company’s non-financial assets noted as of December 31, 2016 or 2015. The Company does not have any liabilities that are recorded at fair value on a non-recurring basis.

Derivative Instruments and Hedging Activities

General Discussion of Derivative Instruments and Hedging Activities [Abstract]

Derivative Instruments and Hedging Activities

Effective April 1, 2010, in order to reduce the volatility of cash outflows that arise from changes in interest rates, the Company entered into two interest rate swap agreements. These interest rate swap agreements are intended to hedge the Company’s mortgage loan related to its headquarters facility in Middletown, Rhode Island by fixing the interest rates specified in the mortgage loan to 5.9% for half of the principal amount outstanding and 6.1% for the remaining half of the principal amount outstanding as of April 1, 2010 until the mortgage loan expires on April 16, 2019. The Company does not use derivatives for speculative purposes. For a derivative that is designated as a cash flow hedge, changes in the fair value of the derivative are recognized in accumulated other comprehensive income ("AOCI") to the extent the derivative is effective at offsetting the changes in the cash flows being hedged until the hedged item affects earnings. To the extent there is any hedge ineffectiveness, changes in fair value relating to the ineffective portion are immediately recognized in earnings in other income (expense) in the Consolidated Statements of Income. The interest rate swap is recorded within accrued other liabilities on the balance sheet. The critical terms of the interest rate swaps were designed to mirror the terms of the Company’s mortgage loans. The Company designated these derivatives as cash flow hedges of the variability of the LIBOR-based interest payments on principal over a nine-year period, which ends on April 1, 2019. As of December 31, 2016, the Company determined that the existence of hedge ineffectiveness, if any, was immaterial and all changes in the fair value of the interest rate caps were recorded in the Consolidated Statements of Comprehensive (Loss) Income as a component of AOCI.

As of December 31, 2016, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk:



Interest Rate Derivatives	Notional (in thousands)		Asset (Liability)		Effective Date	Maturity Date	Index	Strike Rate
Interest rate swap	$	1,476	(76	)	April 1, 2010	April 1, 2019	1-month LIBOR	5.91	%
Interest rate swap	$	1,476	(82	)	April 1, 2010	April 1, 2019	1-month LIBOR	6.07	%
