Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Description of Business Westell Technologies, Inc. (the Company) is a holding company. Its wholly-owned subsidiary, Westell, Inc., designs and distributes telecommunications products which are sold primarily to major telephone companies. Noran Tel, Inc. is a wholly-owned subsidiary of Westell, Inc. Noran Tel's operations focus on power distribution product development and sales of Company products in Canada. On April 1, 2013, Westell, Inc. acquired 100% of the outstanding shares of Kentrox, Inc. (Kentrox). Kentrox designed and distributed intelligent site management solutions that provided comprehensive monitoring, management and control of any site. On March 1, 2014, Westell, Inc. acquired 100% of the outstanding shares of Cellular Specialties, Inc. (CSI). CSI designs and develops in-building wireless solutions, including distributed antenna systems (DAS) products and small cell connectivity equipment. The assets and liabilities acquired and the results of operations relating to Kentrox and CSI are included in the Company's Condensed Consolidated Financial Statements from the dates of acquisitions. Basis of Presentation and Reporting The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. The Condensed Consolidated Financial Statements have been prepared using generally accepted accounting principles (GAAP) in the United States for interim financial reporting, and consistent with the instructions of Form 10-Q and Article 10 of Regulation S-X, and accordingly they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company’s Annual Report on Form 10-K/A for the year ended March 31, 2015 . All intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited interim financial statements included herein reflect all adjustments, consisting of normal recurring adjustments, necessary to present fairly the Company’s condensed consolidated financial position and the results of operations, comprehensive income (loss) and cash flows at September 30, 2015 , and for all periods presented. The results of operations for the periods presented are not necessarily indicative of the results that may be expected for fiscal year 2016 . 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 that affect revenue and expenses during the periods reported. Estimates are used when accounting for the allowance for uncollectible accounts receivable, net realizable value of inventory, product warranty accrued, relative selling prices, stock-based compensation, goodwill and intangible assets fair value, depreciation, income taxes, and contingencies, among other things. Actual results could differ from those estimates. Recently Issued Accounting Pronouncements Adopted In September 2015, the FASB issued ASU 2015-16, Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments (ASU 2015-16), which eliminates the requirement to retroactively account for measurement-period adjustments to provisional amounts recognized in a business combination. Under the new guidance, the measurement-period adjustments must be recognized in the period in which adjustments are determined, including the effect on earnings of any amounts that would have been recorded in previous periods. The standard is effective for our financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. We adopted this guidance in the second quarter of fiscal year 2016. Recently Issued Accounting Pronouncements Not Yet Adopted In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory (ASU 2015-11). The core principle of the guidance is that an entity should measure inventory at the "lower of cost and net realizable value" and options that currently exist for "market value" will be eliminated. The ASU defines net realizable value as the "estimated selling prices in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation." The standard is effective for our financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on our consolidated financial statements. In June 2015, the FASB issued ASU No. 2015-10, Technical Corrections and Improvements (ASU 2015-10) , which covers a wide range of topics in the FASB Accounting Standards Codification (the "Codification"). The amendments in this update represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect of current accounting practice or create a significant administrative cost at most entities. The amendments in ASU 2015-10 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early application is permitted. The Company is in the process of evaluating the impact the adoption of ASU 2015-10 will have its Consolidated Financial Statements or related disclosures. In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15) , to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company does not expect the adoption of ASU 2014-15 to have a significant impact on its Consolidated Financial Statements or related disclosures. In May 2014, the FASB issued ASU No. 2014-09, Revenue From Contracts With Customers (ASU 2014-09) , that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The ASU is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. ASU 2014-09 was originally effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and early adoption was not permitted. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date , as a revision to ASU 2014-09, which revised the effective date to fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, but not prior to periods beginning after December 15, 2016 (the original adoption date per ASU 2014-09). The Company is currently assessing the transition methods and impact these ASUs will have on its Consolidated Financial Statements.

Restructuring Charges [Abstract]
Restructuring Charge	Restructuring Charge In the fourth quarter of fiscal year 2015, the Company approved a plan to restructure its business, including reduction of headcount and consolidation of office space within the Aurora headquarters facility, with the intent to optimize operations. The restructuring was substantially completed during the fourth quarter of fiscal year 2015 and impacted 17 employees. The Company recognized a restructuring expense of $3.2 million in the three months ended March 31, 2015, inclusive of a non-cash charge of $2.7 million related to a loss on a lease, net of sublease income. The Company recognized a restructuring expense of $17,000 in the six months ended September 30, 2015 related to employee separation costs. As of September 30, 2015, $1.1 million and $1.1 million of the restructuring costs primarily related to the office space are unpaid and accrued on the Condensed Consolidated Balance Sheets presented in accrued restructuring and accrued restructuring non-current, respectively. As of March 31, 2015, $1.2 million and $1.6 million of the restructuring costs primarily related to the office space are unpaid and accrued on the Condensed Consolidated Balance Sheets presented in accrued restructuring and accrued restructuring non-current, respectively. The restructuring costs are expected to be paid by fiscal year 2018 concurrent with the termination date of the contractual lease. In the first quarter of fiscal year 2014, the Company acquired Kentrox and identified redundant employees who exited the business after a period of time. The Company recognized a restructuring expense of $55,000 in the six months ended September 30, 2014 for severance for these transitional employees. Total liability for restructuring charges and their utilization for the six months ended September 30, 2015 , and 2014 , are summarized as follows: Six months ended September 30, 2015 Six months ended September 30, 2014 (in thousands) Employee-related Other costs Total Employee-related Liability at beginning of period $ 15 $ 2,788 $ 2,803 $ 57 Charged 17 — 17 55 Paid (32 ) (597 ) (629 ) (112 ) Liability at end of period $ — $ 2,191 $ 2,191 $ —

Segment Reporting [Abstract]
Interim Segment Information	Interim Segment Information Segment information is presented in accordance with a “management approach", which designates the internal reporting used by the chief operating decision-maker (CODM) for making decisions and assessing performance as the source of the Company's reportable segments. Westell’s Chief Executive Officer is the CODM. The CODM continues to define segment profit as gross profit less research and development expenses. The accounting policies of the segments are the same as those for Westell Technologies, Inc. described in the summary of significant accounting policies. The Company’s two reportable segments are as follows: In-Building Wireless (IBW) Segment The IBW segment solutions include distributed antenna systems (DAS) conditioners, high-performance digital repeaters and bi-directional amplifiers (BDAs), and system components and antennas, all used by wireless service providers and neutral-party hosts to fine tune radio frequency (RF) signals that helps extend coverage to areas not served well or at all by traditional cell sites. Communication Solutions Group (CSG) Segment The CSG segment solutions include intelligent site management (ISM), cell site optimization (CSO), and outside plant (OSP) as follows: • ISM solutions include a suite of Remote monitoring and control devices which, when combined with the Company's Optima management system, provides comprehensive machine-to-machine (M2M) communications that enable operators to remotely monitor, manage, and control site infrastructure and support systems. • CSO solutions consist of tower mounted amplifiers (TMAs), small outdoor-hardened units mounted next to antennas on cell towers, enabling wireless service providers to improve the overall performance of a cell site, including increasing data throughput and reducing dropped connections. • OSP solutions, which are sold to wireline and wireless service providers as well as industrial network operators, consist of a broad range of offerings, including cabinets, enclosures, and mountings; synchronous optical networks/time division multiplexing (SONET/TDM) network interface units; power distribution units; copper and fiber connectivity panels; hardened Ethernet switches; and systems integration services.

Share-based Compensation [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Westell Technologies, Inc. 2015 Omnibus Incentive Compensation Plan (the "2015 Plan") was approved at the annual meeting of stockholders on September 16, 2015. The 2015 Plan replaces the Westell Technologies, Inc. 2004 Stock Incentive Plan (the "2004 Plan"). The 2015 Plan includes a total of 4,200,000 shares of Class A Common Stock ("Shares") plus the number of Shares reserved for issuance under the 2004 Plan that have not been granted or reserved for issuance under an outstanding award may be issued under the 2015 Omnibus Plan. If any award granted under the 2015 Plan or the 2004 Plan is canceled, terminates, expires, or lapses for any reason, any Shares subject to such award shall again be available for the grant of an award under the 2015 Plan.

Product Warranties Disclosures [Abstract]
Product Warranties	Product Warranties The Company’s products carry a limited warranty ranging from one to five years for the products within the IBW segment and one to seven years for products within the CSG segment. The specific terms and conditions of those warranties vary depending upon the customer and the products sold. Factors that enter into the estimate of the Company’s warranty reserve include: the number of units shipped, anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the reserve as necessary. The current portions of the warranty reserve are $379,000 and $383,000 as of September 30, 2015 , and March 31, 2015 , respectively, and are presented on the Condensed Consolidated Balance Sheets as Accrued expenses. The non-current portions of the warranty reserves are $141,000 and $122,000 as of September 30, 2015 , and March 31, 2015 , respectively, and are presented on the Condensed Consolidated Balance Sheets in Other non-current liabilities. The following table presents the changes in the Company’s product warranty reserve: Three months ended September 30, Six months ended September 30, (in thousands) 2015 2014 2015 2014 Total product warranty reserve at the beginning of the period $ 548 $ 424 $ 505 $ 328 Warranty expense to cost of revenue 56 288 153 410 Utilization (84 ) (46 ) (138 ) (72 ) Total product warranty reserve at the end of the period $ 520 $ 666 $ 520 $ 666

Guarantees [Abstract]
Equity Method Investment [Text Block]	Variable Interest Entity and Guarantee The Company has a 50% equity ownership in AccessTel Kentrox Australia PTY LTD (AKA). AKA distributes network management solutions provided by the Company and the other 50% owner to one customer. The Company holds equal voting control with the other owner. All actions of AKA are decided at the board level by majority vote. The Company evaluated ASC 810, Consolidations , and concluded that AKA is a variable interest entity (VIE). The Company has concluded that it is not the primary beneficiary of AKA and therefore consolidation is not required. As of September 30, 2015 , and March 31, 2015 , the carrying amount of the Company's investment in AKA was approximately $0.1 million , which is presented on the Condensed Consolidated Balance Sheets within Other non-current assets. The Company's revenue from sales to AKA for the three months ended September 30, 2015 and 2014 was $0.9 million and $0.9 million , respectively. The Company's revenue from sales to AKA for the six months ended September 30, 2015 and 2014 was $1.4 million and $1.1 million , respectively. Accounts receivable from AKA was $0.8 million and $0.4 million as of September 30, 2015 , and March 31, 2015 , respectively. Deferred revenue which primarily relates to AKA maintenance contracts was $1.5 million and $1.1 million as of September 30, 2015 and March 31, 2015 , respectively. The Company also has provided an unlimited guarantee for the performance of the other 50% owner in AKA, which primarily provides support and engineering services to the customer. This guarantee was put in place at the request of the AKA customer. The guarantee, which is estimated to have a maximum potential future payment of $0.7 million , will stay in place as long as the contract between AKA and the customer is in place. The Company would have recourse against the other 50% owner in AKA in the event the guarantee is triggered. The Company determined that it could perform on the obligation it guaranteed at a positive rate of return and therefore did not assign value to the guarantee. The Company's exposure to loss as a result of its involvement with AKA, exclusive of lost profits, is limited to the items noted above.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each interim period, the Company makes its best estimate of the effective tax rate expected to be applicable for the full fiscal year and uses that rate to provide for income taxes on a current year-to-date basis before discrete items. If a reliable estimate cannot be made, the Company may make a reasonable estimate of the annual effective tax rate, including use of the actual effective rate for the year-to-date. The impact of discrete items is recorded in the quarter in which they occur. The Company utilizes the liability method of accounting for income taxes and deferred taxes which are determined based on the differences between the financial statements and tax basis of assets and liabilities given the enacted tax laws. The Company evaluates the need for valuation allowances on the net deferred tax assets under the rules of ASC 740, Income Taxes. In assessing the realizability of the Company's deferred tax assets, the Company considered whether it is more likely than not that some or all of the deferred tax assets will be realized through the generation of future taxable income. In making this determination, the Company assessed all of the evidence available at the time including recent earnings, forecasted income projections and historical performance. The Company determined that the negative evidence outweighed the objectively verifiable positive evidence and recorded a full valuation allowance against deferred tax assets. The Company will continue to reassess realizability going forward. The Company recorded $20,000 and $82,000 of income tax benefit in the three and six months ended September 30, 2015 , using an effective income tax rate of 1.2% . The Company recorded $69,000 and $98,000 of income tax benefit in the three and six months ended September 30, 2014 , using an effective rate of 0.4% plus discrete items. The effective rate is impacted by the intraperiod allocation as a result of loss from continuing operations and income from discontinued operations, loss in a foreign jurisdiction with no valuation allowance, and states which base tax on gross margin and not pretax income.

Commitments and Contingencies	Commitments and Contingencies Obligations Future obligations and commitments, which are comprised of future minimum lease payments, inventory purchase obligations, and contingent consideration, decreased $1.1 million in the six months ended September 30, 2015 , to $16.1 million , from $17.2 million at March 31, 2015 . This decrease included a $0.5 million payment of contingent consideration. Purchase obligations relate to inventory that arises in the normal course of business operations. Future obligations and commitments as of September 30, 2015 , consisted of the following: Payments due within (in thousands) Year 1 Year 2 Year 3 Year 4 Year 5 Thereafter Total Purchase obligations (1) $ 9,354 $ — $ — $ — $ — $ — $ 9,354 Future minimum operating lease payments 3,170 2,097 370 116 — — 5,753 Contingent consideration 1,030 — — — — — 1,030 Future obligations and commitments $ 13,554 $ 2,097 $ 370 $ 116 $ — $ — $ 16,137 (1) A reserve for a net loss on firm purchase commitments of $414,000 and $675,000 is recorded on the balance sheet as of September 30, 2015 and March 31, 2015, respectively. Litigation and Contingency Reserves The Company and its subsidiaries are involved in various assertions, claims, proceedings and requests for indemnification concerning intellectual property, including patent infringement suits involving technologies that may be incorporated in the Company’s products, which are being handled and defended in the ordinary course of business. These matters are in various stages of investigation and litigation, and they are being vigorously defended. Although the Company does not expect that the outcome in any of these matters, individually or collectively, will have a material adverse effect on its financial condition or results of operations, litigation is inherently unpredictable. Therefore, judgments could be rendered, or settlements entered, that could adversely affect the Company’s operating results or cash flows in a particular period. The Company routinely assesses all of its litigation and threatened litigation as to the probability of ultimately incurring a liability, and it records its best estimate of the ultimate loss in situations where it assesses the likelihood of loss as probable. As of September 30, 2015 , and March 31, 2015, the Company has not recorded any contingent liability attributable to existing litigation. As of March 31, 2015 , the Company had total contingency reserves of $0.4 million related to the discontinued operations of ConferencePlus which was sold in fiscal year 2012. The contingency reserves are classified as Accrued expenses on the Consolidated Balance Sheets. In the six months ended September 30, 2015, a pre-tax gain of $0.4 million resulted from the expiration of an indemnity period and release of a contingency reserve related to the sale of ConferencePlus and was recorded in discontinued operations. Additionally, the Company has a contingent cash consideration payable related to an acquisition. The contingent consideration becomes payable based upon the profitability of the acquired products for post-closing periods through June 30, 2016, and is offset by working capital adjustments and other indemnification claims. The maximum earn-out that could be paid before offsets is $3.5 million . As of September 30, 2015 , and March 31, 2015 , the fair value of the contingent consideration liability after offsetting a working capital adjustment and an indemnification claim for warranty obligations was $1.0 million and $1.6 million , respectively (See Note 11 ).

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined by ASC 820, Fair Value Measurements and Disclosures (ASC 820) , as the price that would be received upon selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: • Level 1 – Quoted prices in active markets for identical assets and liabilities. • Level 2 – Quoted prices in active markets for similar assets and liabilities, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. The Company’s money market funds are measured using Level 1 inputs. The contingent consideration described in Note 9 is measured using Level 3 inputs. The following table presents available-for sale securities and non-financial liabilities measured at fair value on a recurring basis and their related valuation inputs as of September 30, 2015 : (in thousands) Total Fair Value Quoted Prices in Significant Other Significant Balance Sheet Assets: Money market funds $ 23,300 $ 23,300 — — Cash and cash Liabilities: Contingent consideration, current $ 1,030 — — $ 1,030 Contingent consideration payable The following table presents financial assets, excluding cash, and non-financial liabilities measured at fair value on a recurring basis and their related valuation inputs as of March 31, 2015 : (in thousands) Total Fair Value Quoted Prices in Significant Other Significant Balance Sheet Assets: Money market funds $ 2,879 $ 2,879 — — Cash and cash Liabilities: Contingent consideration, current $ 1,184 — — $ 1,184 Contingent consideration payable Contingent consideration, non- $ 400 — — $ 400 Contingent The fair value of the money market funds approximates their carrying amounts due to the short-term nature of these financial assets. In connection with an acquisition in the quarter ended June 30, 2012, payment of a portion of the purchase price is contingent upon the profitability of the acquired products for post-closing periods through June 30, 2016, and may be offset by working capital adjustments and other indemnification claims. The Company estimates the fair value of contingent consideration as the present value of the expected payments over the term of the arrangement based on financial forecasts of future profitability of the acquired products, and reaching the forecast. This estimate is subject to ongoing evaluation. Inputs such as forecasted revenue for the acquired products and acquired product profitability are the most significant drivers of the fair value measurement and are based on full attainment. Significant decreases in any of those inputs would result in a significantly lower fair value measurement. The actual cash payment could range from $1.9 million to $2.7 million of which $1.6 million has been paid as of September 30, 2015. The fair value measurement of contingent consideration as of September 30, 2015 , and March 31, 2015 , encompasses the following significant unobservable inputs: ($ in thousands) Unobservable Inputs September 30, 2015 March 31, 2015 Estimated earn-out contingent consideration $ 3,361 $ 3,500 Working capital and other adjustment (444 ) (444 ) Indemnification related to warranty claims (303 ) (303 ) Discount rate 6.3 % 6.3 % Approximate timing of cash flows 0.9 years 1.4 years The following table summarizes contingent consideration activity: (in thousands) Balance as of March 31, 2015 $ 1,584 Contingent consideration – payments (454 ) Contingent consideration – change in fair value in General and Administrative expense (100 ) Balance as of September 30, 2015 $ 1,030

Payments for Repurchase of Equity [Abstract]
Share Repurchases	Share Repurchases In August 2011, the Board of Directors authorized a share repurchase program whereby the Company may repurchase up to an aggregate of $20.0 million of its outstanding Class A Common Stock (the "authorization”). There were no shares repurchased under this authorization during the six months ended September 30, 2015 or September 30, 2014. There was approximately $0.1 million remaining for additional share repurchases under this program as of September 30, 2015 . Additionally, in the six months ended September 30, 2015 and September 30, 2014, the Company repurchased 73,765 and 215,890 shares of Class A Common Stock, respectively, from certain employees that were surrendered to satisfy the minimum statutory tax withholding obligations on the vesting of restricted stock, RSUs and PSUs. These repurchases are not included in the authorized share repurchase program and had a weighted-average purchase price of $1.15 and $3.19 per share, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Condensed consolidated financial statements	The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries. The Condensed Consolidated Financial Statements have been prepared using generally accepted accounting principles (GAAP) in the United States for interim financial reporting, and consistent with the instructions of Form 10-Q and Article 10 of Regulation S-X, and accordingly they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in the Company’s Annual Report on Form 10-K/A for the year ended March 31, 2015 . All intercompany accounts and transactions have been eliminated in consolidation.
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 that affect revenue and expenses during the periods reported. Estimates are used when accounting for the allowance for uncollectible accounts receivable, net realizable value of inventory, product warranty accrued, relative selling prices, stock-based compensation, goodwill and intangible assets fair value, depreciation, income taxes, and contingencies, among other things. Actual results could differ from those estimates.
New Accounting Pronouncements	Recently Issued Accounting Pronouncements Adopted In September 2015, the FASB issued ASU 2015-16, Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments (ASU 2015-16), which eliminates the requirement to retroactively account for measurement-period adjustments to provisional amounts recognized in a business combination. Under the new guidance, the measurement-period adjustments must be recognized in the period in which adjustments are determined, including the effect on earnings of any amounts that would have been recorded in previous periods. The standard is effective for our financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. We adopted this guidance in the second quarter of fiscal year 2016. Recently Issued Accounting Pronouncements Not Yet Adopted In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory (ASU 2015-11). The core principle of the guidance is that an entity should measure inventory at the "lower of cost and net realizable value" and options that currently exist for "market value" will be eliminated. The ASU defines net realizable value as the "estimated selling prices in the ordinary course of business, less reasonably predictable cost of completion, disposal, and transportation." The standard is effective for our financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on our consolidated financial statements. In June 2015, the FASB issued ASU No. 2015-10, Technical Corrections and Improvements (ASU 2015-10) , which covers a wide range of topics in the FASB Accounting Standards Codification (the "Codification"). The amendments in this update represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect of current accounting practice or create a significant administrative cost at most entities. The amendments in ASU 2015-10 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early application is permitted. The Company is in the process of evaluating the impact the adoption of ASU 2015-10 will have its Consolidated Financial Statements or related disclosures. In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (ASU 2014-15) , to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company does not expect the adoption of ASU 2014-15 to have a significant impact on its Consolidated Financial Statements or related disclosures. In May 2014, the FASB issued ASU No. 2014-09, Revenue From Contracts With Customers (ASU 2014-09) , that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The ASU is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. ASU 2014-09 was originally effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and early adoption was not permitted. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date , as a revision to ASU 2014-09, which revised the effective date to fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, but not prior to periods beginning after December 15, 2016 (the original adoption date per ASU 2014-09). The Company is currently assessing the transition methods and impact these ASUs will have on its Consolidated Financial Statements.
