Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	Note 1. Basis of Presentation Business Description Airgain, Inc. (the Company) was incorporated in the State of California on March 20, 1995, and reincorporated in the State of Delaware on August 15, 2016. The Company is a leading provider of embedded antenna technologies used to enable high performance wireless networking across a broad range of home, enterprise, and industrial devices. The Company designs, develops, and engineers its antenna products for original equipment and design manufacturers worldwide. The Company’s main office is in San Diego, California with office space and research facilities in San Diego, California, Taipei, Taiwan, Shenzhen and Jiangsu, China and Cambridgeshire, United Kingdom. Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Interim financial results are not necessarily indicative of results anticipated for the full year. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the financial statements and accompanying notes included in the Company’s final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on August 12, 2016. The condensed balance sheet as of December 31, 2015 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. The condensed statement of operations for the three months ended June 30, 2016 and June 30, 2015 and the six months ended June 30, 2016 and June 30, 2015, and the balance sheet data as of June 30, 2016 have been prepared on the same basis as the audited financial statements. In the opinion of management, the accompanying unaudited condensed financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation of results of the Company’s operations and financial position for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2016 or for any future period. In July 2016, the Company effected a one-for-ten reverse stock split of its common stock. All issued and outstanding common stock, and per share amounts contained in the financial statements have been retroactively adjusted to reflect this reverse stock split for all periods presented. Inventory The vast majority of the Company’s products are manufactured by third parties that retain ownership of the inventory until title is transferred to the customer at the shipping point. In certain instances, shipping terms are delivery at place and the Company is responsible for arranging transportation and delivery of goods ready for unloading at the name place. The Company bears all risk involved in bringing the goods to the named place and records the related inventory in transit to the customer as inventory on the accompanying balance sheet. Segment Information The Company’s operations are located primarily in the United States, and most of its assets are located in San Diego, California. The Company operates in one segment related to the sale of antenna products. The Company’s chief operating decision-maker is its chief executive officer, who reviews operating results on an aggregate basis and manages the Company’s opertions as a single operating segment. Initial Public Offering On August 17, 2016, the Company completed its initial public offering (IPO) in which it issued and sold 1.5 million shares of common stock at a public offering price of $8.00 per share. The Company received net proceeds of approximately $9.8 million after deducting underwriting discounts and commissions of $0.8 million and estimated offering-related transaction costs of approximately $1.4 million. Upon the closing of the IPO, all shares of the Company’s then-outstanding preferred redeemable convertible stock and preferred convertible stock automatically converted into an aggregate of 3,080,733 shares of common stock and the Company issued 1,945,892 shares of common stock in satisfaction of accumulated dividends. On August 29, 2016 the underwriters exercised their over-allotment option to purchase an additional 200,100 shares of common stock at the public offering price of $8.00 per share, which resulted in net proceeds to the Company of approximately $1.5 million, after deducting underwriting discounts, commissions and estimated offering-related transaction costs of approximately $0.1 million. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include valuation of the preferred redeemable convertible stock warrant liability and determining the assumptions used in measuring stock-based compensation expense.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies as described in the Proscpectus that have had a material impact on the Company’s unaudited condensed financial statements and related notes. Fair Value Measurements The carrying values of the Company’s financial instruments, including cash, trade accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to the short maturity of these instruments. Fair value measurements are market-based measurements, not entity-specific measurements. Therefore, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. The Company follows a three-level hierarchy to prioritize the inputs used in the valuation techniques to derive fair values. The basis for fair value measurements for each level within the hierarchy is described below: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. • Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable in active markets. Because some of the inputs to the Company’s valuation model were either not observable or were not derived principally from or corroborated by observable market data by correlation or other means, the warrant liability was classified as Level 3 in the fair value hierarchy. The following table provides a summary of the recognized liabilities carried at fair value on a recurring basis: Balance as of December 31, 2015 Level 1 Level 2 Level 3 Liabilities: Warrant liability (note 10) $ — — $ 709,504 The Company’s accounting policy is to recognize transfers between levels of the fair value hierarchy on the date of the event or change in circumstances that caused the transfer. There were no transfers into or out of Level 1, Level 2, or Level 3 for the six months ended June 30, 2016 and the year ended December 31, 2015. The following table provides a rollforward of the Company’s Level 3 fair value measurements during the six months ended June 30, 2016 and 2015: Six Months Ended June 30, 2016 2015 Beginning balance $ 709,504 $ 809,974 Change in fair value of warrant liability (460,289 ) (258,138 ) Conversion of warrants (249,215 ) — Ending balance $ — $ 551,836 In May 2016, the warrants were amended such that the warrants became immediately exercisable into shares of the Company’s common stock. Concurrent with such amendment, the holders of the outstanding warrants elected to net exercise the warrants, and the Company issued an aggregate of 127,143 shares of common stock. A final valuation of the warrants was completed and the remaining balance was reclassified to additional paid in capital. Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (FASB), issued Accounting Standards Update, or ASU, No. 2016-09 Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09). ASU 2016-09 simplifies several aspects 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. For public entities, ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact the guidance will have on its financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (ASU 2016-2), which requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets. The new standard is effective January 1, 2019. The Company is evaluating the effect that ASU 2014-09 will have on its financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on the Company’s ongoing financial reporting. In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This guidance simplifies the presentation of deferred income taxes by requiring that deferred tax liabilities and assets all be classified as noncurrent in a classified statement of financial position. The guidance is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company does not expect the adoption of this guidance to have a material impact on its financial statements. In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Business Combinations (Topic 815): Simplifying the Accounting Measurement-Period Adjustments. This guidance requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The guidance is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material impact on its financial statements. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. The update requires companies to measure certain inventory at the lower of cost and net realizable value. This guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those years on a prospective basis. Early application is permitted. The Company does not expect the adoption of this guidance to have a material impact on its financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with customers (ASU 2014-09), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard will replace most existing revenue recognition guidance in GAAP when it becomes effective. The new standard is effective for us on January 1, 2019. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of that standard on the Company’s ongoing financial reporting.

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	Note 3. Net Income (Loss) Per Share Basic net income or loss per share is calculated by dividing net income or loss available to common stockholders by the weighted average shares of common stock outstanding for the period. The per share computations reflect the stock split as noted in note 16. Diluted net income or loss per share is calculated by dividing net income or loss by the weighted average shares of common stock outstanding for the period plus amounts representing the dilutive effect of securities that are convertible into common stock.

Acquisition

Business Combinations [Abstract]
Acquisition	Note 4. Acquisition On December 17, 2015, the Company executed and entered into an asset purchase agreement for certain North American assets of Skycross, Inc. (Skycross), a manufacturer of advanced antenna and radio-frequency solutions. As a result of the acquisition, the Company expects to benefit from the acquisition primarily through the addition of new customers. The goodwill of $1,249,956 arising from the acquisition relates to expected synergies and cost reductions through economies of scale. Upon fulfillment of the contingent consideration arrangement, the amount of goodwill expected to be deductible for tax purposes is $1,249,956. In addition to the $4.0 million paid up front, the purchase price also includes a contingent consideration arrangement. The $1.0 million of deferred consideration is contingent upon the later of (i) the expiration of the Transition Services Agreement between the Company and Skycross, Inc. which defines transition services to be provided by Skycross to the Company and (ii) the date on which the Company has received copies of third party approvals with respect to each customer and program that was purchased. The potential undiscounted amount of all future payments that could be required to be paid under the contingent consideration arrangement is between $0.0 and $1.0 million. The fair value of the contingent consideration was estimated by applying the income approach. The income approach is based on estimating the value of the present worth of future net cash flows. The following table summarizes the consideration paid and the amounts of estimated fair value of the assets acquired and liabilities assumed at the acquisition date. Consideration: Cash $ 4,000,000 Contingent consideration arrangement 1,000,000 Fair value of total consideration transferred $ 5,000,000 Recognized amounts of identifiable assets acquired and liabilities assumed: Accounts receivable $ 429,267 Intangible assets 3,497,000 Current liabilities (176,223 ) Total identifiable net assets acquired 3,750,044 Goodwill 1,249,956 Total $ 5,000,000 The fair value of accounts receivable was $429,267 at the date of acquisition. The contingent consideration of $1.0 million is included in the deferred purchase price balance on the accompanying balance sheet as of June 30, 2016. Revenue associated with the acquired Skycross assets since the date of acquisition was $1.4 million and $2.4 million for the three months ended June 30, 2016 and for the six months ended June 30, 2016, respectively. Cost of goods sold associated with the acquired Skycross assets since the date of acquisition was $0.4 million and $0.8 million for the three months ended June 30, 2016 and for the six months ended June 30, 2016, respectively. The acquired assets were not managed as a discrete business by the previous owner. Accordingly, the historical financial information for the assets acquired was impracticable to obtain, and inclusion of pro forma information would require the Company to make estimates and assumptions regarding these assets’ historical financial results that may not be reasonable or accurate. As a result, pro forma results are not presented. It is not practicable to determine net income included in the Company’s operating results relating to Skycross assets since the date of acquisition because the assets have been fully integrated into the Company’s operations, and the operating results of the Skycross assets can therefore not be separately identified.

Long-term Notes Payable (including current portion) and Line of Credit In June 2012, the Company amended its line of credit with Silicon Valley Bank. The amended revolving line of credit facility allows for an advance up to $3.0 million. The facility bears interest at the U.S. prime rate (3.5% as of December 31, 2015) plus 1.25%. The revolving facility is available as long as the Company maintains a liquidity ratio of cash and cash equivalents plus accounts receivable to outstanding debt under the facility of 1.25 to 1.00; otherwise, the facility reverts to its previous eligible receivables financing arrangement. The amended facility matures in April 2018. The bank has a first security interest in all the Company’s assets excluding intellectual property, for which the bank has received a negative pledge. There was no balance owed on the line of credit as of June 30, 2016 and December 31, 2015. In December 2013, the Company further amended its revolving line of credit with Silicon Valley Bank to include a growth capital term loan of up to $750,000. The growth capital term loan requires interest only payments through June 30, 2014 at which point it is to be repaid in 32 equal monthly installments of interest and principal.

The Company must maintain a liquidity ratio of cash and cash equivalents plus accounts receivable to outstanding debt under the facility of greater than or equal to 1.00 to 1.00. As of June 30, 2016 and December 31, 2015, $203,471 and $346,895 was outstanding under this loan, respectively. The remaining principal payments on the growth capital term loan subsequent to June 30, 2016 are as follows: Year ending: 2016 $ 148,273 2017 55,198 $ 203,471 In December 2015, the Company entered into a loan agreement with Silicon Valley Bank in the amount of $4.0 million.

Income Tax Disclosure [Abstract]
Income Taxes	Note 8. Income Taxes The Company’s effective tax rate may vary from the U.S. federal statutory tax rate due to the change in the mix of earnings in tax jurisdictions with different statutory rates, benefits related to tax credits, and the tax impact of non-deductible expenses and other permanent differences between income before income taxes and taxable income. The effective tax rate for the three and six months ended June 30, 2016 was 0.06%. The variance from the U.S. federal statutory tax rate of 34% was primarily attributable to the utilization of deferred tax attributes that had a full valuation allowance as well as nondeductible meals and entertainment expenses, nondeductible incentive stock option compensation expenses, and nontaxable warrant adjustments. Deferred income taxes are provided for temporary differences in recognizing certain income and expense items for financial and reporting purposes. A valuation allowance has been recorded to fully offset the deferred tax asset as it is more likely than not that the asset will not be realized. As of June 30, 2016, the Company has available $25.5 million in federal and $18.7 million in state net operating loss carryforwards to offset future taxable income. Current federal and state tax laws include substantial restrictions on the annual utilization of net operating loss and tax credit carryforwards in the event of an ownership change as defined. Accordingly, the Company’s ability to utilize net operating loss and tax credit carryforwards may be limited as a result of such ownership change. Such information could result in the expiration of carryforwards before they are utilized.

The fair value of the warrants was estimated using a combination of an option-pricing model and current value model under the probability-weighted return method, using significant unobservable inputs (Level 3 inputs) including: management’s cash flow projections; probability and timing of potential liquidity scenarios; weighted-average cost of capital that included the addition of a company specific risk premium to account for uncertainty associated with the Company achieving future cash flows; selection of appropriate market comparable transactions and multiples; expected volatility; and risk-free rate. The Company used a combination of discounted cash flow, guideline public company and market transaction valuation techniques in estimating the fair value of the warrant liability at each reporting date. The discount rates used were 20% and 21% at May 24, 2016 and December 31, 2015, respectively. The fair value of the warrants was $249,215 and $709,504 as of May 24, 2016 and December 31, 2015, respectively.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Interim financial results are not necessarily indicative of results anticipated for the full year. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the financial statements and accompanying notes included in the Company’s final prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on August 12, 2016. The condensed balance sheet as of December 31, 2015 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. The condensed statement of operations for the three months ended June 30, 2016 and June 30, 2015 and the six months ended June 30, 2016 and June 30, 2015, and the balance sheet data as of June 30, 2016 have been prepared on the same basis as the audited financial statements. In the opinion of management, the accompanying unaudited condensed financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation of results of the Company’s operations and financial position for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2016 or for any future period. In July 2016, the Company effected a one-for-ten reverse stock split of its common stock. All issued and outstanding common stock, and per share amounts contained in the financial statements have been retroactively adjusted to reflect this reverse stock split for all periods presented.
Inventory	Inventory The vast majority of the Company’s products are manufactured by third parties that retain ownership of the inventory until title is transferred to the customer at the shipping point. In certain instances, shipping terms are delivery at place and the Company is responsible for arranging transportation and delivery of goods ready for unloading at the name place. The Company bears all risk involved in bringing the goods to the named place and records the related inventory in transit to the customer as inventory on the accompanying balance sheet.
Segment Information	Segment Information The Company’s operations are located primarily in the United States, and most of its assets are located in San Diego, California. The Company operates in one segment related to the sale of antenna products. The Company’s chief operating decision-maker is its chief executive officer, who reviews operating results on an aggregate basis and manages the Company’s opertions as a single operating segment.
Initial Public Offering	Initial Public Offering On August 17, 2016, the Company completed its initial public offering (IPO) in which it issued and sold 1.5 million shares of common stock at a public offering price of $8.00 per share. The Company received net proceeds of approximately $9.8 million after deducting underwriting discounts and commissions of $0.8 million and estimated offering-related transaction costs of approximately $1.4 million. Upon the closing of the IPO, all shares of the Company’s then-outstanding preferred redeemable convertible stock and preferred convertible stock automatically converted into an aggregate of 3,080,733 shares of common stock and the Company issued 1,945,892 shares of common stock in satisfaction of accumulated dividends. On August 29, 2016 the underwriters exercised their over-allotment option to purchase an additional 200,100 shares of common stock at the public offering price of $8.00 per share, which resulted in net proceeds to the Company of approximately $1.5 million, after deducting underwriting discounts, commissions and estimated offering-related transaction costs of approximately $0.1 million.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include valuation of the preferred redeemable convertible stock warrant liability and determining the assumptions used in measuring stock-based compensation expense.
Fair Value Measurements	Fair Value Measurements The carrying values of the Company’s financial instruments, including cash, trade accounts receivable, accounts payable, and accrued liabilities approximate their fair values due to the short maturity of these instruments. Fair value measurements are market-based measurements, not entity-specific measurements. Therefore, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. The Company follows a three-level hierarchy to prioritize the inputs used in the valuation techniques to derive fair values. The basis for fair value measurements for each level within the hierarchy is described below: • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. • Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable in active markets. Because some of the inputs to the Company’s valuation model were either not observable or were not derived principally from or corroborated by observable market data by correlation or other means, the warrant liability was classified as Level 3 in the fair value hierarchy. The following table provides a summary of the recognized liabilities carried at fair value on a recurring basis: Balance as of December 31, 2015 Level 1 Level 2 Level 3 Liabilities: Warrant liability (note 10) $ — — $ 709,504 The Company’s accounting policy is to recognize transfers between levels of the fair value hierarchy on the date of the event or change in circumstances that caused the transfer. There were no transfers into or out of Level 1, Level 2, or Level 3 for the six months ended June 30, 2016 and the year ended December 31, 2015. The following table provides a rollforward of the Company’s Level 3 fair value measurements during the six months ended June 30, 2016 and 2015: Six Months Ended June 30, 2016 2015 Beginning balance $ 709,504 $ 809,974 Change in fair value of warrant liability (460,289 ) (258,138 ) Conversion of warrants (249,215 ) — Ending balance $ — $ 551,836 In May 2016, the warrants were amended such that the warrants became immediately exercisable into shares of the Company’s common stock. Concurrent with such amendment, the holders of the outstanding warrants elected to net exercise the warrants, and the Company issued an aggregate of 127,143 shares of common stock. A final valuation of the warrants was completed and the remaining balance was reclassified to additional paid in capital.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (FASB), issued Accounting Standards Update, or ASU, No. 2016-09 Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09). ASU 2016-09 simplifies several aspects 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. For public entities, ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. The Company is currently evaluating the impact the guidance will have on its financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (ASU 2016-2), which requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets. The new standard is effective January 1, 2019. The Company is evaluating the effect that ASU 2014-09 will have on its financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on the Company’s ongoing financial reporting. In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. This guidance simplifies the presentation of deferred income taxes by requiring that deferred tax liabilities and assets all be classified as noncurrent in a classified statement of financial position. The guidance is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company does not expect the adoption of this guidance to have a material impact on its financial statements. In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Business Combinations (Topic 815): Simplifying the Accounting Measurement-Period Adjustments. This guidance requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The guidance is effective for fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2015. The Company does not expect the adoption of this guidance to have a material impact on its financial statements. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. The update requires companies to measure certain inventory at the lower of cost and net realizable value. This guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those years on a prospective basis. Early application is permitted. The Company does not expect the adoption of this guidance to have a material impact on its financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with customers (ASU 2014-09), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard will replace most existing revenue recognition guidance in GAAP when it becomes effective. The new standard is effective for us on January 1, 2019. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of that standard on the Company’s ongoing financial reporting.
