Accounting Policies [Abstract]
Summary of Operations and Significant Accounting Policies	Note 1. Summary of Operations and Significant Accounting Policies Description of Business TPI Composites, Inc. is the holding company that conducts substantially all of its business operations through its direct and indirect subsidiaries (collectively, the Company). The Company was founded in 1968 and has been producing composite wind blades since 2001. The Company’s knowledge and experience of composite materials and manufacturing originates with its predecessor company, Tillotson Pearson Inc., a leading manufacturer of high-performance sail and powerboats along with a wide range of composite structures used in other industrial applications. Following the separation from the boat building business in 2004, the Company reorganized in Delaware as LCSI Holding, Inc. and then changed its corporate name to TPI Composites, Inc. in 2008. Today, the Company is headquartered in Scottsdale, Arizona and has expanded its global footprint to include domestic facilities in Newton, Iowa; Fall River, Massachusetts; Warren, Rhode Island and Santa Teresa, New Mexico and international facilities in Dafeng, China; Taicang Port, China; Taicang City, China; Juárez, Mexico and Izmir, Turkey. Initial Public Offering and Stock Split In July 2016, the Company completed an initial public offering (IPO) of 7,187,500 shares of the Company’s common stock at a price of $11.00 per share, which included 937,500 shares issued pursuant to the underwriters’ over-allotment option. Certain of the Company’s existing shareholders, a director and executive officers purchased an aggregate of 1,250,000 shares of common stock in the IPO included in the total issuance above. The net proceeds from the IPO were $67.2 million after deducting underwriting discounts and offering expenses. Immediately prior to the closing of the IPO, all shares of the then-outstanding redeemable preferred shares converted into an aggregate of 21,110,204 shares of common stock and the redeemable preferred share warrants converted on a net issuance basis into 120,923 shares of common stock. In addition, concurrent with the closing of the IPO, certain subordinated convertible promissory notes in the aggregate principal and interest amount of $11.9 million were converted into 1,079,749 shares of common stock at the public offering price of $11.00 per share. Prior to the IPO, in July 2016 the Company amended its amended and restated certificate of incorporation to effect a 360-for-1 forward stock split of its common stock. As a result of the stock split, the Company has adjusted the share amounts authorized and issuable under the share-based compensation plans. All share and per share common stock information (including the share-based compensation plans) referenced throughout the unaudited condensed consolidated financial statements and notes thereto have been retroactively adjusted to reflect this stock split. The stock split did not cause an adjustment to the par value of the authorized shares of common stock. Basis of Presentation The Company divides its business operations into four geographic operating segments—the United States, Asia, Mexico and EMEA, as follows: • The U.S. segment includes (1) the manufacturing of wind blades at the Newton, Iowa plant, (2) the manufacturing of precision molding and assembly systems used for the manufacture of wind blades in the Warren, Rhode Island facility, (3) the manufacturing of composite solutions for the transportation industry, which the Company also conducts in its Rhode Island and Massachusetts facilities and (4) its corporate headquarters, the costs of which are included in general and administrative expenses. • The Asia segment includes (1) the manufacturing of wind blades at a facility in Taicang Port, China and in two facilities in Dafeng, China, (2) the manufacturing of precision molding and assembly systems in the Taicang City, China facility, (3) the manufacture of components in a second Taicang Port, China facility and (4) wind blade inspection and repair services. • The Mexico segment manufactures wind blades from two facilities in Juárez, Mexico, one of which commenced operations in early 2014 and the second during the third quarter of 2016. The Mexico segment has also entered into a new lease agreement with a third party for a third manufacturing facility in Juárez, Mexico, and expects to commence operations in this new facility in the first quarter of 2017. • The EMEA segment manufactures wind blades from two facilities in Izmir, Turkey. The Company entered into a joint venture with ALKE Insaat Sanayive Ticaret A.S. (ALKE) in March 2012 to produce wind blades in the first Turkey plant and in December 2013 became the sole owner of the Turkey operation with the acquisition of the remaining 25% interest owned primarily by ALKE. The EMEA segment commenced operations in the second facility during the third quarter of 2016. The accompanying consolidated financial statements include the accounts of TPI Composites, Inc. and all majority owned subsidiaries. All significant intercompany transactions and balances have been eliminated. The condensed consolidated financial statements included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC) and should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2015 included in the Company’s Registration Statement on Form S-1. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been condensed or omitted, as permitted by the SEC, although the Company believes the disclosures that are made are adequate to make the information presented herein not misleading. The accompanying condensed consolidated financial statements reflect, in the opinion of management, all normal recurring adjustments necessary to present fairly the Company’s financial position at September 30, 2016, and the results of the Company’s operations, comprehensive income (loss) and cash flows for the periods presented. The Company derived the December 31, 2015 condensed consolidated balance sheet data from audited financial statements, but does not include all disclosures required by GAAP. Interim results for the three and nine months ended September 30, 2016 and 2015 are not necessarily indicative of the results to be expected for the full years. Warranty Expense The Company provides a limited warranty for its precision molding and assembly systems and wind blade products, including parts and labor, with terms and conditions that vary depending on the product sold, for periods that range from two to five years. Warranty expense is recorded based upon estimates of future repairs using a probability-based methodology. Once the warranty period has expired, any remaining unused warranty accrual for the specific products is reversed against the current year warranty expense amount. Warranty accrual consisted of the following (in thousands): 2016 Warranty accrual at beginning of year $ 13,596 Accrual during the period 19,132 Cost of warranty services provided during the period (385 ) Reduction of reserves (1,286 ) Warranty accrual at end of the period $ 31,057 In June 2016, the Company entered into a settlement agreement and release with one of its customers to resolve a potential warranty claim related to wind blades primarily manufactured in 2014 in the Company’s Turkey facility. The settlement agreement and release requires the Company to make a cash payment to the customer, replace or repair a specified number of wind blades and provide margin concessions on certain products to be produced by the Company. The expected aggregate cost to the Company of fulfilling its obligations under the settlement agreement and release is estimated to be $15.0 million, all of which has been accrued. Net Income Per Share Calculation The basic net income per common share is computed by dividing the net income by the weighted-average number of common shares outstanding during a period. Diluted net income per common share is computed by dividing the net income, adjusted on an as-if-converted basis, by the weighted-average number of common shares outstanding plus potentially dilutive securities. The table below reflects the calculation of the weighted-average number of common shares outstanding, on an as if converted basis, used in computing basic and diluted earnings per common share (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Basic weighted-average shares outstanding 27,284 4,238 12,042 4,238 Effect of dilutive stock options and warrants 91 — 91 — Diluted weighted-average shares outstanding 27,375 4,238 12,133 4,238 The Company has potentially dilutive securities outstanding that are not shown in a diluted net loss per share calculation because their effect would be anti-dilutive for the three and nine months ended September 30, 2015. The potentially dilutive securities excluded from the calculation include common shares issued upon conversion or exercise of options and warrants. Assuming that the IPO had occurred on January 1, 2015, diluted earnings per share would have been $0.08 and a loss of $0.06 for the three months ended September 30, 2016 and 2015, respectively. For the nine months ended September 30, 2016 and 2015, diluted earnings per share would have been $0.48 and a loss of $0.11, respectively. Use of Estimates The preparation of these condensed consolidated 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Recently Issued Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers The new requirements are effective for the Company beginning January 1, 2018, and may be implemented either retrospectively for all periods presented, or as a cumulative-effect adjustment as of the date of adoption. Adoption as of January 1, 2017 is permitted. The Company expects to adopt Topic 606 as of January 1, 2017 with retrospective application to January 1, 2015 through December 31, 2016. Based on the Company’s preliminary evaluation of the new standard, revenue recognition in accordance with Topic 606 differs from the current guidance provided by GAAP as outlined in the SEC’s Staff Accounting Bulletin 104, which requires the Company to defer recognition of revenue until the risk of loss has passed to the customer and delivery has been made or a fixed delivery schedule has been provided by the customer. Since the Company’s products have no alternative use to the Company due to contractual restrictions placed by each customer on the technical specifications and design of the products, the Company’s preliminary assessment is that revenue upon adoption of Topic 606 will likely be recognized over time during the course of the production process and before the product is delivered to the customer. The Company expects that the adoption of Topic 606 will have a material impact on the amount of net sales, cost of goods sold and income from operations reported in the Statements of Operations in future periods. In accordance with Topic 606, revenues will be recognized over the time period of the production process, whereas currently it is recognized upon delivery to the client. Further, since revenue will be recognized over time for manufacturing contracts, future net sales will include amounts related to products that are in production as of the period end. Finally, the gross margin realized in the period may be impacted by the changes related to the timing and amount of revenue recognized for products in the production process. The changes noted above involving the timing of revenue recognition will materially impact the amount of reported assets and liabilities associated with our manufacturing contracts. Upon adoption of Topic 606, the Company will include amounts recognized in revenue for products in production in contract assets, which differs from the current practice of including the balances in inventory and will include an amount for the margin recognized to date. The Company believes that it will no longer report inventory held for customer orders since revenue will be recognized over time during the course of the production process and before the product is delivered to the customer. Contract liabilities will be reported for amounts collected from customers in advance of the production of products. The amount of deferred revenue will be substantially reduced as revenue for products will be recognized over time. The Company does not anticipate a change in the timing of cash receipts and payments from customers as customers will continue to be invoiced as products are completed; however, the impact to the amounts reported in the statements of cash flows operating activities upon application of Topic 606 is expected to be material. The Company has a project plan in place for the transition to revenue recognition in accordance with Topic 606 including necessary changes to accounting processes and procedures, the chart of accounts, the system of internal control and retrospective application of the standard to periods beginning December 31, 2014 through December 31, 2016. The Company expects to complete the plan in time to report in accordance with Topic 606 for the first quarterly filing on Form 10-Q for the period ended March 31, 2017.

Text Block [Abstract]
Significant Risks and Uncertainties	Note 2. Significant Risks and Uncertainties The Company’s revenues and receivables are from a small number of customers. As such, the Company’s production levels are dependent on these customers’ orders. See note 12, Concentration of Customers. The Company maintains its U.S. cash in bank deposit accounts that, at times, exceed U.S. federally insured limits. U.S. bank accounts are guaranteed by the Federal Deposit Insurance Corporation (FDIC) in an amount up to $250,000 during 2016 and 2015. At September 30, 2016 and December 31, 2015, the Company had $89.8 million and $33.2 million, respectively, of cash in deposit accounts in U.S. banks, which was in excess of FDIC limits. The Company has not experienced losses in any such accounts in the past. The Company also maintains cash in bank deposit accounts outside the U.S. with no deposit insurance. This includes $10.6 million in China, $5.8 million in Turkey and $0.6 million in Mexico as of September 30, 2016. The Company has not experienced losses in these accounts in the past.

Related Party Transactions [Abstract]
Related-Party Transactions	Note 3. Related-Party Transactions Related party transactions include transactions between the Company and certain of its affiliates. The following transactions were in the normal course of operations and were measured at the exchange amount, which is the amount of consideration established and agreed to by the parties. The Company has entered into several agreements with subsidiaries of General Electric Company and consolidated affiliates (GE) for the manufacture and supply of wind blades. In October 2016, the Company extended the term of certain of its supply agreements with GE through December 31, 2020 and entered into a new supply agreement as described in note 14, Subsequent Events For the three months ended September 30, 2016 and 2015, the Company recorded related-party sales with GE of $98.1 million and $82.2 million, respectively, and for the nine months ended September 30, 2016 and 2015, the Company recorded related-party sales with GE of $292.4 million and $213.9 million, respectively. The Company has entered into five separate supply agreements with GE to manufacture wind blades in Newton, Iowa; Taicang Port, China; Juárez, Mexico (2) and Izmir, Turkey. As a result of the supply agreements, GE is the Company’s largest customer. As of September 30, 2016 and December 31, 2015, the Company had accounts receivables related to sales to GE of approximately $29.2 million and $19.0 million, respectively. In January 2016, the Company entered into an agreement with GE and received an advance of $2.0 million, which the Company repaid in full in August 2016. Certain of the Company’s existing stockholders, consisting of entities associated with Element Partners, Angeleno Group and Landmark Partners, each of which is an affiliate of a member of the board of directors, as well as certain executive officers and a director, purchased an aggregate of 1,250,000 shares of common stock in the IPO. In addition, all outstanding obligations under the Company’s subordinated convertible promissory notes, including accrued interest, held by certain existing stockholders, including Element Partners, Angeleno Group and Landmark Partners, were converted into an aggregate of 1,079,749 shares of common stock concurrent with the closing of the IPO at the public offering price of $11.00 per share.

Share-Based Compensation Plans	Note 9. Share-Based Compensation Plans The Company granted stock option awards during the nine months ended September 30, 2016 to certain employees under the Amended and Restated 2015 Stock Option and Incentive Plan (the 2015 Plan). Each award granted prior to the consummation of the IPO included a performance condition that required the completion of an initial public offering by the Company and a required vesting period of one to four years commencing upon achievement of the performance condition. As the IPO was consummated in July 2016, the Company began recording compensation expense in July 2016 for the requisite service period from the grant date through the IPO date with the balance of the share-based compensation to be expensed over the remaining vesting period. Total share-based compensation expense recognized during the three and nine months ended September 30, 2016 was $8.1 million, of which approximately $6.3 million related to the service period from the grant date to through June 30, 2016. Of the $8.1 million expense, $1.2 million is included in cost of goods sold and the remaining $6.9 million included in general and administrative expenses. The amount recorded related to restricted stock units was $3.0 million while $5.1 million related to stock options. Furthermore, the total tax benefits related to share-based compensation expense was $1.8 million for the three and nine months ended September 30, 2016. No share-based compensation costs were capitalized during the nine months ended September 30, 2016. As of September 30, 2016, the unamortized cost of the outstanding restricted stock units was $3.3 million, which the Company expects to recognize in the consolidated financial statements over a weighted-average period of approximately 1.9 years. The total unrecognized cost related to non-vested stock option awards was $8.2 million as of September 30, 2016. The Company expects to recognize such costs in the consolidated financial statements over a weighted-average period of approximately 2.2 years. The following table summarizes the activity of the stock options and restricted stock units (RSU) under the Company’s incentive plans: Stock Options RSUs Shares Available for Grant Shares Weighted- Average Exercise Price Options Exercisable Units Weighted- Average Grant Date Fair Value Balance as of December 31, 2015 3,392,141 3,261,663 $ 11.90 35,703 731,880 $ 10.89 Granted (486,000 ) 486,000 17.37 — — Forfeited/cancelled 519,995 (424,235 ) 11.78 (95,760 ) 10.87 Balance as of September 30, 2016 3,426,136 3,323,428 12.71 25,828 636,120 10.90 The following table summarizes the outstanding and exercisable stock option awards as of September 30, 2016: Options Outstanding Options Exercisable Range of Exercise Prices: Shares Weighted- Average Remaining Contractual Life (in years) Weighted- Average Exercise Price Shares Weighted- Average Exercise Price $8.49 25,828 3.3 $ 8.49 25,828 $ 8.49 $10.87 - $11.00 2,322,000 8.7 10.87 — — $14.31 - $16.53 640,800 9.3 16.41 — — $18.70 334,800 10.0 18.70 — — $8.49 to $18.70 3,323,428 8.9 12.71 25,828 8.49

Accounting Policies [Abstract]
Description of Business	Description of Business TPI Composites, Inc. is the holding company that conducts substantially all of its business operations through its direct and indirect subsidiaries (collectively, the Company). The Company was founded in 1968 and has been producing composite wind blades since 2001. The Company’s knowledge and experience of composite materials and manufacturing originates with its predecessor company, Tillotson Pearson Inc., a leading manufacturer of high-performance sail and powerboats along with a wide range of composite structures used in other industrial applications. Following the separation from the boat building business in 2004, the Company reorganized in Delaware as LCSI Holding, Inc. and then changed its corporate name to TPI Composites, Inc. in 2008. Today, the Company is headquartered in Scottsdale, Arizona and has expanded its global footprint to include domestic facilities in Newton, Iowa; Fall River, Massachusetts; Warren, Rhode Island and Santa Teresa, New Mexico and international facilities in Dafeng, China; Taicang Port, China; Taicang City, China; Juárez, Mexico and Izmir, Turkey.
Initial Public Offering and Stock Split	Initial Public Offering and Stock Split In July 2016, the Company completed an initial public offering (IPO) of 7,187,500 shares of the Company’s common stock at a price of $11.00 per share, which included 937,500 shares issued pursuant to the underwriters’ over-allotment option. Certain of the Company’s existing shareholders, a director and executive officers purchased an aggregate of 1,250,000 shares of common stock in the IPO included in the total issuance above. The net proceeds from the IPO were $67.2 million after deducting underwriting discounts and offering expenses. Immediately prior to the closing of the IPO, all shares of the then-outstanding redeemable preferred shares converted into an aggregate of 21,110,204 shares of common stock and the redeemable preferred share warrants converted on a net issuance basis into 120,923 shares of common stock. In addition, concurrent with the closing of the IPO, certain subordinated convertible promissory notes in the aggregate principal and interest amount of $11.9 million were converted into 1,079,749 shares of common stock at the public offering price of $11.00 per share. Prior to the IPO, in July 2016 the Company amended its amended and restated certificate of incorporation to effect a 360-for-1 forward stock split of its common stock. As a result of the stock split, the Company has adjusted the share amounts authorized and issuable under the share-based compensation plans. All share and per share common stock information (including the share-based compensation plans) referenced throughout the unaudited condensed consolidated financial statements and notes thereto have been retroactively adjusted to reflect this stock split. The stock split did not cause an adjustment to the par value of the authorized shares of common stock.
Basis of Presentation	Basis of Presentation The Company divides its business operations into four geographic operating segments—the United States, Asia, Mexico and EMEA, as follows: • The U.S. segment includes (1) the manufacturing of wind blades at the Newton, Iowa plant, (2) the manufacturing of precision molding and assembly systems used for the manufacture of wind blades in the Warren, Rhode Island facility, (3) the manufacturing of composite solutions for the transportation industry, which the Company also conducts in its Rhode Island and Massachusetts facilities and (4) its corporate headquarters, the costs of which are included in general and administrative expenses. • The Asia segment includes (1) the manufacturing of wind blades at a facility in Taicang Port, China and in two facilities in Dafeng, China, (2) the manufacturing of precision molding and assembly systems in the Taicang City, China facility, (3) the manufacture of components in a second Taicang Port, China facility and (4) wind blade inspection and repair services. • The Mexico segment manufactures wind blades from two facilities in Juárez, Mexico, one of which commenced operations in early 2014 and the second during the third quarter of 2016. The Mexico segment has also entered into a new lease agreement with a third party for a third manufacturing facility in Juárez, Mexico, and expects to commence operations in this new facility in the first quarter of 2017. • The EMEA segment manufactures wind blades from two facilities in Izmir, Turkey. The Company entered into a joint venture with ALKE Insaat Sanayive Ticaret A.S. (ALKE) in March 2012 to produce wind blades in the first Turkey plant and in December 2013 became the sole owner of the Turkey operation with the acquisition of the remaining 25% interest owned primarily by ALKE. The EMEA segment commenced operations in the second facility during the third quarter of 2016. The accompanying consolidated financial statements include the accounts of TPI Composites, Inc. and all majority owned subsidiaries. All significant intercompany transactions and balances have been eliminated. The condensed consolidated financial statements included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC) and should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2015 included in the Company’s Registration Statement on Form S-1. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been condensed or omitted, as permitted by the SEC, although the Company believes the disclosures that are made are adequate to make the information presented herein not misleading. The accompanying condensed consolidated financial statements reflect, in the opinion of management, all normal recurring adjustments necessary to present fairly the Company’s financial position at September 30, 2016, and the results of the Company’s operations, comprehensive income (loss) and cash flows for the periods presented. The Company derived the December 31, 2015 condensed consolidated balance sheet data from audited financial statements, but does not include all disclosures required by GAAP. Interim results for the three and nine months ended September 30, 2016 and 2015 are not necessarily indicative of the results to be expected for the full years.
Warranty Expense	Warranty Expense The Company provides a limited warranty for its precision molding and assembly systems and wind blade products, including parts and labor, with terms and conditions that vary depending on the product sold, for periods that range from two to five years. Warranty expense is recorded based upon estimates of future repairs using a probability-based methodology. Once the warranty period has expired, any remaining unused warranty accrual for the specific products is reversed against the current year warranty expense amount. Warranty accrual consisted of the following (in thousands): 2016 Warranty accrual at beginning of year $ 13,596 Accrual during the period 19,132 Cost of warranty services provided during the period (385 ) Reduction of reserves (1,286 ) Warranty accrual at end of the period $ 31,057 In June 2016, the Company entered into a settlement agreement and release with one of its customers to resolve a potential warranty claim related to wind blades primarily manufactured in 2014 in the Company’s Turkey facility. The settlement agreement and release requires the Company to make a cash payment to the customer, replace or repair a specified number of wind blades and provide margin concessions on certain products to be produced by the Company. The expected aggregate cost to the Company of fulfilling its obligations under the settlement agreement and release is estimated to be $15.0 million, all of which has been accrued.
Net Income Per Share Calculation	Net Income Per Share Calculation The basic net income per common share is computed by dividing the net income by the weighted-average number of common shares outstanding during a period. Diluted net income per common share is computed by dividing the net income, adjusted on an as-if-converted basis, by the weighted-average number of common shares outstanding plus potentially dilutive securities. The table below reflects the calculation of the weighted-average number of common shares outstanding, on an as if converted basis, used in computing basic and diluted earnings per common share (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Basic weighted-average shares outstanding 27,284 4,238 12,042 4,238 Effect of dilutive stock options and warrants 91 — 91 — Diluted weighted-average shares outstanding 27,375 4,238 12,133 4,238 The Company has potentially dilutive securities outstanding that are not shown in a diluted net loss per share calculation because their effect would be anti-dilutive for the three and nine months ended September 30, 2015. The potentially dilutive securities excluded from the calculation include common shares issued upon conversion or exercise of options and warrants. Assuming that the IPO had occurred on January 1, 2015, diluted earnings per share would have been $0.08 and a loss of $0.06 for the three months ended September 30, 2016 and 2015, respectively. For the nine months ended September 30, 2016 and 2015, diluted earnings per share would have been $0.48 and a loss of $0.11, respectively.
Use of Estimates	Use of Estimates The preparation of these condensed consolidated 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers The new requirements are effective for the Company beginning January 1, 2018, and may be implemented either retrospectively for all periods presented, or as a cumulative-effect adjustment as of the date of adoption. Adoption as of January 1, 2017 is permitted. The Company expects to adopt Topic 606 as of January 1, 2017 with retrospective application to January 1, 2015 through December 31, 2016. Based on the Company’s preliminary evaluation of the new standard, revenue recognition in accordance with Topic 606 differs from the current guidance provided by GAAP as outlined in the SEC’s Staff Accounting Bulletin 104, which requires the Company to defer recognition of revenue until the risk of loss has passed to the customer and delivery has been made or a fixed delivery schedule has been provided by the customer. Since the Company’s products have no alternative use to the Company due to contractual restrictions placed by each customer on the technical specifications and design of the products, the Company’s preliminary assessment is that revenue upon adoption of Topic 606 will likely be recognized over time during the course of the production process and before the product is delivered to the customer. The Company expects that the adoption of Topic 606 will have a material impact on the amount of net sales, cost of goods sold and income from operations reported in the Statements of Operations in future periods. In accordance with Topic 606, revenues will be recognized over the time period of the production process, whereas currently it is recognized upon delivery to the client. Further, since revenue will be recognized over time for manufacturing contracts, future net sales will include amounts related to products that are in production as of the period end. Finally, the gross margin realized in the period may be impacted by the changes related to the timing and amount of revenue recognized for products in the production process. The changes noted above involving the timing of revenue recognition will materially impact the amount of reported assets and liabilities associated with our manufacturing contracts. Upon adoption of Topic 606, the Company will include amounts recognized in revenue for products in production in contract assets, which differs from the current practice of including the balances in inventory and will include an amount for the margin recognized to date. The Company believes that it will no longer report inventory held for customer orders since revenue will be recognized over time during the course of the production process and before the product is delivered to the customer. Contract liabilities will be reported for amounts collected from customers in advance of the production of products. The amount of deferred revenue will be substantially reduced as revenue for products will be recognized over time. The Company does not anticipate a change in the timing of cash receipts and payments from customers as customers will continue to be invoiced as products are completed; however, the impact to the amounts reported in the statements of cash flows operating activities upon application of Topic 606 is expected to be material. The Company has a project plan in place for the transition to revenue recognition in accordance with Topic 606 including necessary changes to accounting processes and procedures, the chart of accounts, the system of internal control and retrospective application of the standard to periods beginning December 31, 2014 through December 31, 2016. The Company expects to complete the plan in time to report in accordance with Topic 606 for the first quarterly filing on Form 10-Q for the period ended March 31, 2017.
