Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Principles of Consolidation These financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Cash and Cash Equivalents We consider all highly liquid temporary investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents consist of bank deposits and highly liquid, interest-bearing money market funds. The Company's cash and cash equivalents are held in a few financial institutions in amounts that exceed the insurance limits of the Federal Deposit Insurance Corporation. However, management believes that the Company's counterparty risks are minimal based on the reputation and history of the institutions selected. Investments Certificates of Deposit We held $12.0 million and $11.4 million in certificates of deposit at December 31, 2015 and December 31, 2014 , respectively. At December 31, 2015 , the certificates of deposit bear interest ranging from 0.25% to 0.90% per annum and have various maturities ranging from less than one month to approximately 15 months . Investments Held to Maturity At December 31, 2015 , our investments held to maturity were comprised of $17.5 million of corporate notes and bonds with various maturities ranging from less than one month to approximately 15 months . The investments have moderate risk with S&P ratings ranging from AA+ to BBB-. We record the amortized cost basis and accrued interest of the corporate notes and bonds in the Consolidated Balance Sheets. We record the interest and amortization of bond premium to interest income in the Consolidated Statements of Income. The following summarizes the amortized cost and estimated fair value of our investments held to maturity at December 31, 2015 and December 31, 2014 : Amortized Cost Gross Unrealized Gain Gross Unrealized (Loss) Fair Value December 31, 2015: (in thousands) Current assets: Investments held to maturity $ 12,444 $ — $ (16 ) $ 12,428 Non current assets: Investments held to maturity 5,039 — (17 ) 5,022 Total $ 17,483 $ — $ (33 ) $ 17,450 December 31, 2014: Current assets: Investments held to maturity $ 11,972 $ — $ (7 ) $ 11,965 Non current assets: Investments held to maturity 4,015 — (16 ) 3,999 Total $ 15,987 $ — $ (23 ) $ 15,964 We evaluate these investments for other-than-temporary impairments on a quarterly basis. We do not believe there was an other-than-temporary impairment for our investments at December 31, 2015 or 2014 . Accounts and Note Receivable Accounts and note receivable are stated at amounts due from customers, net of an allowance for doubtful accounts. We generally do not require that our customers provide collateral. The Company determines its allowance for doubtful accounts by considering a number of factors, including the credit risk of specific customers, the customer’s ability to pay current obligations, historical trends, economic and market conditions and the age of the receivable. Accounts are considered past due when the balance has been outstanding for ninety days past negotiated credit terms. Past due accounts are generally written-off against the allowance for doubtful accounts only after all collection attempts have been exhausted. Concentration of Credit Risk Our customers are concentrated primarily in the domestic commercial and industrial new construction and replacement markets. To date, our sales have been primarily to the domestic market, with foreign sales accounting for approximately 4% , 6% and 5% of revenues for the years ended December 31, 2015 , 2014 and 2013 , respectively. One customer accounted for 10% or more of our sales during 2015 . No customer accounted for 10% or more of our sales during 2014 or 2013 . No customer accounted for 5% or more of our accounts receivable balance at December 31, 2015 or 2014 . Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents, receivables, accounts payable and accrued liabilities approximate fair value because of the short-term maturity of the items. The carrying amount of the Company's revolving line of credit, and other payables, approximate their fair values either due to their short term nature, the variable rates associated with the debt or based on current rates offered to the Company for debt with similar characteristics. Inventories Inventories are valued at the lower of cost or market using the first-in, first-out (“FIFO”) method. Cost in inventory includes purchased parts and materials, direct labor and applied manufacturing overhead. We establish an allowance for excess and obsolete inventories based on product line changes, the feasibility of substituting parts and the need for supply and replacement parts. Property, Plant and Equipment Property, plant and equipment, including significant improvements, are recorded at cost, net of accumulated depreciation. Repairs and maintenance and any gains or losses on disposition are included in operations. Depreciation is computed using the straight-line method over the following estimated useful lives: Buildings 3-40 years Machinery and equipment 3-15 years Furniture and fixtures 3-7 years Impairment of Long-Lived Assets We review long-lived assets for possible impairment when events or changes in circumstances indicate, in management’s judgment, that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset or asset group to its estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the undiscounted cash flows are less than the carrying amount of the asset or asset group, an impairment loss is recognized for the amount by which the carrying amount of the asset or asset group exceeds its fair value. Research and Development The costs associated with research and development for the purpose of developing and improving new products are expensed as incurred. For the years ended December 31, 2015 , 2014 , and 2013 research and development costs amounted to approximately $7.5 million, $6.3 million , and $5.2 million , respectively. Advertising Advertising costs are expensed as incurred. Advertising expense for the years ended December 31, 2015 , 2014 , and 2013 was approximately $1.2 million, $1.0 million , and $0.9 million , respectively. Shipping and Handling We incur shipping and handling costs in the distribution of products sold that are recorded in cost of sales. Shipping charges that are billed to the customer are recorded in revenues and as an expense in cost of sales. For the years ended December 31, 2015 , 2014 and 2013 shipping and handling fees amounted to approximately $9.6 million, $8.5 million , and $7.9 million , respectively. Income Taxes Income taxes are accounted for under the asset and liability method. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the book carrying amounts and the tax basis of assets and liabilities. We establish accruals for unrecognized tax positions when it is more likely than not that our tax return positions may not be fully sustained. The Company records a valuation allowance for deferred tax assets when, in the opinion of management, it is more likely than not that deferred tax assets will not be realized. Share-Based Compensation The Company recognizes expense for its share-based compensation based on the fair value of the awards that are granted. The Company’s share-based compensation plans provide for the granting of stock options and restricted stock. The fair values of stock options are estimated at the date of grant using the Black-Scholes-Merton option valuation model. The use of the Black-Scholes-Merton option valuation model requires the input of subjective assumptions. Measured compensation cost, net of estimated forfeitures, is recognized ratably over the vesting period of the related share-based compensation award. Forfeitures are estimated based on the Company's historical experience. The fair value of restricted stock awards is determined based on the market value of the Company’s shares on the grant date and the compensation expense is recognized on a straight-line basis during the service period of the respective grant. Derivative Instruments In the course of normal operations, the Company occasionally enters into contracts such as forward priced physical contracts for the purchase of raw materials that qualify for and are designated as normal purchase or normal sale contracts. Such contracts are exempted from the fair value accounting requirements and are accounted for at the time product is purchased or sold under the related contract. The Company does not engage in speculative transactions, nor does the Company hold or issue financial instruments for trading purposes. Revenue Recognition We recognize revenues from sales of products when title and risk of ownership pass to the customer. Final sales prices are fixed and based on purchase orders. Sales allowances and customer incentives are treated as reductions to sales and are provided for based on historical experiences and current estimates. Sales of our products are moderately seasonal with the peak period being July - November of each year. In addition, the Company presents revenues net of sales tax and net of certain payments to our independent manufacturer representatives (“Representatives”). Representatives are national companies that are in the business of providing HVAC units and other related products and services to customers. The end user customer orders a bundled group of products and services from the Representative and expects the Representative to fulfill the order. Only after the specifications are agreed to by the Representative and the customer, and the decision is made to use an AAON HVAC unit, will we receive notice of the order. We establish the amount we must receive for our HVAC unit (“minimum sales price”), but do not control the total order price which is negotiated by the Representative with the end user customer. We are responsible for billings and collections resulting from all sales transactions, including those initiated by our Representatives. The Representatives submit the total order price to us for invoicing and collection. The total order price includes our minimum sales price and could contain an additional amount which may include both the Representatives’ fee and amounts due for additional products and services required by the customer. These additional products and services may include controls purchased from another manufacturer to operate the unit, start-up services, and curbs for supporting the unit (“Third Party Products”). All are associated with the purchase of a HVAC unit but may be provided by the Representative or another third party. The Company is under no obligation related to Third Party Products. The Representatives’ fee and Third Party Products amounts (“Due to Representatives”) are paid only after all amounts associated with the order are collected from the customer. The Due to Representatives amount is paid only after all amounts associated with the order are collected from the customer. The amount of payments to our representatives was $55.4 million, $59.7 million , and $63.0 million for each of the years ended December 31, 2015 , 2014 , and 2013 , respectively. The Company also sells extended warranties on parts for various lengths of time ranging from six months to 10 years. Revenue for these separately priced warranties is deferred and recognized on a straight-line basis over the separately priced warranty period. Insurance Reserves Under the Company’s insurance programs, coverage is obtained for significant liability limits as well as those risks required to be insured by law or contract. It is the policy of the Company to self-insure a portion of certain expected losses related primarily to workers’ compensation and medical liability. Provisions for losses expected under these programs are recorded based on the Company’s estimates of the aggregate liabilities for the claims incurred. Product Warranties A provision is made for the estimated cost of maintaining product warranties to customers at the time the product is sold based upon historical claims experience by product line. The Company records a liability and an expense for estimated future warranty claims based upon historical experience and management's estimate of the level of future claims. Changes in the estimated amounts recognized in prior years are recorded as an adjustment to the liability and expense in the current year. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Because these estimates and assumptions require significant judgment, actual results could differ from those estimates and could have a significant impact on our results of operations, financial position and cash flows. We reevaluate our estimates and assumptions as needed, but at a minimum on a quarterly basis. The most significant estimates include, but are not limited to, the allowance for doubtful accounts, inventory reserves, warranty accrual, workers compensation accrual, medical insurance accrual, share-based compensation and income taxes. Actual results could differ materially from those estimates. |

Note Receivable | Note Receivable In connection with the closure of our Canadian facility on May 18, 2009, we sold land and a building in September 2010 and assumed a note receivable from the borrower secured by the property. The $1.1 million , 15 year note has an interest rate of 4.0% and is payable to us monthly, and has a $0.6 million balloon payment due in October 2025 . Interest payments are recognized in interest income. We evaluate the note for impairment on a quarterly basis. We determine the note receivable to be impaired if we are uncertain of its collectability based on the contractual terms. At December 31, 2015 and 2014 , there was no impairment. |

Income Taxes | Income Taxes The provision (benefit) for income taxes consists of the following: Years Ending December 31, 2015 2014 2013 (in thousands) Current $ 24,439 $ 26,199 $ 20,341 Deferred 1,172 (2,111 ) (1,594 ) $ 25,611 $ 24,088 $ 18,747 The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate before the provision for income taxes. The reconciliation of the federal statutory income tax rate to the effective income tax rate is as follows: Years Ending December 31, 2015 2014 2013 Federal statutory rate 35 % 35 % 35 % State income taxes, net of federal benefit 5 % 5 % 4 % Domestic manufacturing deduction (3 )% (4 )% (4 )% Other (1 )% (1 )% (2 )% 36 % 35 % 33 % Other primarily relates to certain domestic credits. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amount used for income tax purposes. The significant components of the Company’s deferred tax assets and liabilities are as follows: December 31, 2015 2014 (in thousands) Deferred income tax assets (liabilities): Accounts receivable and inventory reserves $ 351 $ 355 Warranty accrual 3,405 3,263 Other accruals 1,248 1,238 Share-based compensation 1,099 707 Donations 691 1,309 Other, net 986 888 Total deferred income tax assets 7,780 7,760 Property & equipment (16,486 ) (15,294 ) Total deferred income tax liabilities $ (16,486 ) $ (15,294 ) Net deferred income tax liabilities $ (8,706 ) $ (7,534 ) In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Taxes , which requires presentation of deferred tax assets and liabilities as non-current in a classified balance sheet. The ASU becomes effective in the annual reporting period beginning after December 31, 2016, including interim reporting periods. Early adoption is allowed as of the beginning of any interim or annual reporting period. The standard permits the use of the retrospective or prospective transition method. We have early adopted the standard effective October 1, 2015, for the interim and annual reporting periods ending December 31, 2015 and have applied the retrospective transition method. The following table displays the prior period quantitative effects on the consolidated balance sheets: December 31, 2014 As Reported As Restated (in thousands) Deferred tax assets $ 6,143 $ — Total current assets 131,083 124,940 Total assets 233,117 226,974 Deferred tax liabilities 13,677 7,534 Total liabilities and stockholders' equity 233,117 226,974 There are no prior period quantitative effects on the consolidated statements of income, stockholders' equity or cash flows. We file income tax returns in the U.S., state and foreign income tax returns jurisdictions. We are subject to U.S. examinations for tax years 2012 to present, and to non-U.S. income tax examinations for the tax years of 2011 to present. In addition, we are subject to state and local income tax examinations for the tax years 2011 to present. The Company continues to evaluate its need to file returns in various state jurisdictions. Any interest or penalties would be recognized as a component of income tax expense. On January 2, 2013 the ATRA was signed into law. Some of the provisions were retroactive to January 1, 2012, including the extension of certain tax credits. Had the ATRA had been enacted prior to January 1, 2013, our overall tax expense for 2013 would have been approximately $0.5 million higher. This was recorded as a reduction in expense in the first quarter of 2013. The Company also had a change in estimate related to the recoverability of certain 2012 tax credits that was recorded in the first quarter of 2013 for approximately $0.6 million . This change in estimate was the result of additional and better information. Had the ATRA impact and the change in estimate been booked in 2012 instead of 2013, our overall effective tax rate would have been approximately 35.3% for the year ended December 31, 2013. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
Share-Based Compensation | Share-Based Compensation We have historically maintained a stock option plan for key employees, directors and consultants (“the 1992 Plan”). The 1992 Plan provided for 14.9 million shares to be issued under the plan in the form of stock options. Under the terms of the plan, the exercise price of shares granted may not be less than 85% of the fair market value at the date of the grant. Options granted to directors prior to May 25, 2004, vest one year from the date of grant and are exercisable for nine years thereafter. Options granted to directors on or after May 25, 2004, vest one-third each year, commencing one year after the date of grant. All other options granted vest at a rate of 20% per year, commencing one year after date of grant, and are exercisable during years 2 - 10 . On May 22, 2007, our stockholders adopted a Long-Term Incentive Plan (“LTIP”) which provides an additional 3.3 million shares that can be granted in the form of stock options, stock appreciation rights, restricted stock awards, performance units and performance awards. Since inception of the Plan, non-qualified stock options and restricted stock awards have been granted with the same vesting schedule as the previous plan. Under the LTIP, the exercise price of shares granted may not be less than 100% of the fair market value at the date of the grant. The total pre-tax compensation cost related to unvested stock options not yet recognized as of December 31, 2015 is $2.4 million and is expected to be recognized over a weighted-average period of 2.05 years. The following weighted average assumptions were used to determine the fair value of the stock options granted on the original grant date for expense recognition purposes for options granted during December 31, 2015 , 2014 and 2013 using a Black Scholes-Merton Model: 2015 2014 2013 Director and Officers: Expected dividend yield $ 0.18 N/A $ 0.08 Expected volatility 44.14 % N/A 47.08 % Risk-free interest rate 1.97 % N/A 1.55 % Expected life (in years) 8 N/A 7 Employees: Expected dividend yield $ 0.22 $ 0.14 $ 0.08 Expected volatility 42.71 % 44.85 % 45.92 % Risk-free interest rate 1.41 % 2.26 % 1.40 % Expected life (in years) 8 8 8 The expected term of the options is based on evaluations of historical and expected future employee exercise behavior. The risk-free interest rate is based on the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life at the grant date. Volatility is based on historical volatility of our stock over time periods equal to the expected life at grant date. The following is a summary of stock options vested and exercisable as of December 31, 2015 : Weighted Average Weighted Range of Number Remaining Average Exercise of Contractual Exercise Intrinsic Prices Shares Life Price Value (in thousands) $4.31 - 8.65 421,237 4.89 $ 7.04 $ 6,814 $8.70 - 22.76 27,134 7.82 15.31 215 $23.57 - 23.57 — 0.00 — — Total 448,371 5.07 $ 7.54 $ 7,029 The following is a summary of stock options vested and exercisable as of December 31, 2014 : Weighted Average Weighted Range of Number Remaining Average Exercise of Contractual Exercise Intrinsic Prices Shares Life Price Value (in thousands) $3.21 - 6.89 411,553 3.46 $ 5.16 $ 7,113 $7.13 - 8.17 81,050 6.54 7.27 1,226 $8.65 - 21.14 175,527 6.53 8.76 2,392 Total 668,130 4.64 $ 6.36 $ 10,731 The following is a summary of stock options vested and exercisable as of December 31, 2013 : Weighted Average Weighted Range of Number Remaining Average Exercise of Contractual Exercise Intrinsic Prices Shares Life Price Value (in thousands) $3.21 - 6.89 422,003 4.09 $ 4.85 $ 6,941 $7.13 - 8.17 63,225 7.45 7.24 889 $8.65 - 9.34 97,887 8.38 8.65 1,238 Total 583,115 5.17 $ 5.75 $ 9,068 A summary of option activity under the plan is as follows: Weighted Average Exercise Options Shares Price Outstanding at December 31, 2014 1,233,911 $ 8.16 Granted 363,895 22.79 Exercised (435,562 ) 6.42 Forfeited or Expired (31,334 ) 14.02 Outstanding at December 31, 2015 1,130,910 $ 13.38 Exercisable at December 31, 2015 448,371 $ 7.54 The total intrinsic value of options exercised during December 31, 2015 , 2014 and 2013 was $7.4 million , $2.8 million and $2.7 million , respectively. The cash received from options exercised during December 31, 2015 , 2014 and 2013 was $2.8 million , $1.3 million and $1.5 million , respectively. The impact of these cash receipts is included in financing activities in the accompanying Consolidated Statements of Cash Flows. Since 2007, as part of the LTIP, the Compensation Committee of the Board of Directors has authorized and issued restricted stock awards to directors and key employees. Restricted stock awards granted to directors vest one-third each year. All other restricted stock awards vest at a rate of 20% per year. The fair value of restricted stock awards is based on the fair market value of AAON common stock on the respective grant dates, reduced for the present value of dividends. These awards are recorded at their fair value on the date of grant and compensation cost is recorded using straight-line vesting over the service period. At December 31, 2015 , unrecognized compensation cost related to unvested restricted stock awards was approximately $4.7 million which is expected to be recognized over a weighted average period of 1.99 years.

Employee Benefits | Employee Benefits Defined Contribution Plan - 401(k ) - We sponsor a defined contribution plan (“the Plan”). Eligible employees may make contributions in accordance with the Plan and IRS guidelines. In addition to the traditional 401(k), eligible employees are given the option of making an after-tax contribution to a Roth 401(k) or a combination of both. The Plan provides for automatic enrollment and for an automatic increase to the deferral percentage at January 1st of each year and each year thereafter. Eligible employees are automatically enrolled in the Plan at a 6% deferral rate and currently contributing employees deferral rates will be increased to 6% unless their current rate is above 6% or the employee elects to decline the automatic enrollment or increase. Under the Plan, through September 30, 2013, the Company contributed a specified percentage of each eligible employee’s compensation. In addition, the Company contributed 1.5% of eligible payroll to the Plan each year. Effective October 1, 2013, the Plan was amended such that the Company contributes 3% of eligible payroll to the Plan for each employee and matches 100% up to 6% of employee contributions of eligible compensation. We contribute in the form of cash and direct the investment to shares of AAON stock. Employees are 100% vested in salary deferral contributions and vest 20% per year at the end of years two through six of employment in employer matching contributions. The additional 3% Company contribution, a Safe-Harbor contribution, vests over two years. Effective January 1, 2016, the Plan has been amended such that the Company will match 175% up to 6% of employee contributions of eligible compensation. The Company will no longer contribute 3% of eligible payroll to the Plan for each employee. The Company will cease paying administrative expenses for the Plan at which time administrative expenses will be paid for by Plan participants. Additionally, Plan participant forfeitures will be used to reduce the cost of the Company contributions. For the years ended December 31, 2015 , 2014 and 2013 we made contributions of $9.0 million , $6.8 million and $3.0 million , respectively. Administrative expenses were approximately $0.1 million , $0.2 million , and $0.2 million for the years ended 2015 , 2014 and 2013 , respectively. Profit Sharing Bonus Plan - We maintain a discretionary profit sharing bonus plan under which approximately 10% of pre-tax profit is paid to eligible employees on a quarterly basis in order to reward employee productivity. Eligible employees are regular full-time employees who are actively employed and working on the first and last days of the calendar quarter and who were employed full-time for at least three full months prior to the beginning of the calendar quarter. Profit sharing expense was $8.0 million , $7.8 million and $6.4 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies We are subject to various claims and legal actions that arise in the ordinary course of business. We closely monitor these claims and legal actions and frequently consult with our legal counsel to determine whether they may, when resolved, have a material adverse effect on our financial position, results of operations or cash flows and we accrue and/or disclose loss contingencies as appropriate. We have concluded that the likelihood is remote that the ultimate resolution of any pending litigation or claims will be material or have a material adverse effect on the Company's business, financial position, results of operations or cash flows. We are occasionally party to short-term, cancellable and occasionally non-cancellable, fixed price contracts with major suppliers for the purchase of raw material and component parts. We expect to receive delivery of raw materials for use in our manufacturing operations. These contracts are not accounted for as derivative instruments because they meet the normal purchase and normal sales exemption. At December 31, 2013, we had one material contractual purchase agreement for approximately $1.4 million that expired in December 2014. |

New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
New Accounting Pronouncements | New Accounting Pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASUs") to the FASB's Accounting Standards Codification. We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers , 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 ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, with the issuance of ASU 2015-14, the FASB amended the effective date for us to January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. We do not expect ASU 2014-09 will have a material effect on our consolidated financial statements and notes thereto. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Taxes , which requires presentation of deferred tax assets and liabilities as non-current in a classified balance sheet. We have early adopted the standard effective October 1, 2015, for the interim and annual reporting periods ending December 31, 2015 and have applied the retrospective transition method. Additional information regarding our adoption is contained in Note 10 to the Consolidated Financial Statements. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , which will address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The ASU becomes effective in the annual reporting period beginning after December 31, 2017, including interim reporting periods. We do not expect ASU 2016-01 will have a material effect on our consolidated financial statements and notes thereto. |

Earnings Per Share | Earnings Per Share Basic net income per share is calculated by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share assumes the conversion of all potentially dilutive securities and is calculated by dividing net income by the sum of the weighted average number of shares of common stock outstanding plus all potentially dilutive securities. Dilutive common shares consist primarily of stock options and restricted stock awards.

Accounting Policies [Abstract] | |
Principles of Consolidation | Principles of Consolidation These financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. |
Cash and Cash Equivalents | Cash and Cash Equivalents We consider all highly liquid temporary investments with original maturity dates of three months or less to be cash equivalents. Cash and cash equivalents consist of bank deposits and highly liquid, interest-bearing money market funds. The Company's cash and cash equivalents are held in a few financial institutions in amounts that exceed the insurance limits of the Federal Deposit Insurance Corporation. However, management believes that the Company's counterparty risks are minimal based on the reputation and history of the institutions selected. |
Investments | Investments Certificates of Deposit We held $12.0 million and $11.4 million in certificates of deposit at December 31, 2015 and December 31, 2014 , respectively. At December 31, 2015 , the certificates of deposit bear interest ranging from 0.25% to 0.90% per annum and have various maturities ranging from less than one month to approximately 15 months . Investments Held to Maturity At December 31, 2015 , our investments held to maturity were comprised of $17.5 million of corporate notes and bonds with various maturities ranging from less than one month to approximately 15 months . The investments have moderate risk with S&P ratings ranging from AA+ to BBB-. We record the amortized cost basis and accrued interest of the corporate notes and bonds in the Consolidated Balance Sheets. We record the interest and amortization of bond premium to interest income in the Consolidated Statements of Income. The following summarizes the amortized cost and estimated fair value of our investments held to maturity at December 31, 2015 and December 31, 2014 : Amortized Cost Gross Unrealized Gain Gross Unrealized (Loss) Fair Value December 31, 2015: (in thousands) Current assets: Investments held to maturity $ 12,444 $ — $ (16 ) $ 12,428 Non current assets: Investments held to maturity 5,039 — (17 ) 5,022 Total $ 17,483 $ — $ (33 ) $ 17,450 December 31, 2014: Current assets: Investments held to maturity $ 11,972 $ — $ (7 ) $ 11,965 Non current assets: Investments held to maturity 4,015 — (16 ) 3,999 Total $ 15,987 $ — $ (23 ) $ 15,964 We evaluate these investments for other-than-temporary impairments on a quarterly basis. We do not believe there was an other-than-temporary impairment for our investments at December 31, 2015 or 2014 . |
Accounts and Note Receivable | Accounts and Note Receivable Accounts and note receivable are stated at amounts due from customers, net of an allowance for doubtful accounts. We generally do not require that our customers provide collateral. The Company determines its allowance for doubtful accounts by considering a number of factors, including the credit risk of specific customers, the customer’s ability to pay current obligations, historical trends, economic and market conditions and the age of the receivable. Accounts are considered past due when the balance has been outstanding for ninety days past negotiated credit terms. Past due accounts are generally written-off against the allowance for doubtful accounts only after all collection attempts have been exhausted. |
Concentration of Credit Risk | Concentration of Credit Risk Our customers are concentrated primarily in the domestic commercial and industrial new construction and replacement markets. To date, our sales have been primarily to the domestic market, with foreign sales accounting for approximately 4% , 6% and 5% of revenues for the years ended December 31, 2015 , 2014 and 2013 , respectively. One customer accounted for 10% or more of our sales during 2015 . No customer accounted for 10% or more of our sales during 2014 or 2013 . No customer accounted for 5% or more of our accounts receivable balance at December 31, 2015 or 2014 . |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents, receivables, accounts payable and accrued liabilities approximate fair value because of the short-term maturity of the items. The carrying amount of the Company's revolving line of credit, and other payables, approximate their fair values either due to their short term nature, the variable rates associated with the debt or based on current rates offered to the Company for debt with similar characteristics. |
Inventories | Inventories Inventories are valued at the lower of cost or market using the first-in, first-out (“FIFO”) method. Cost in inventory includes purchased parts and materials, direct labor and applied manufacturing overhead. We establish an allowance for excess and obsolete inventories based on product line changes, the feasibility of substituting parts and the need for supply and replacement parts. |
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment, including significant improvements, are recorded at cost, net of accumulated depreciation. Repairs and maintenance and any gains or losses on disposition are included in operations. Depreciation is computed using the straight-line method over the following estimated useful lives: Buildings 3-40 years Machinery and equipment 3-15 years Furniture and fixtures 3-7 years |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets We review long-lived assets for possible impairment when events or changes in circumstances indicate, in management’s judgment, that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset or asset group to its estimated undiscounted future cash flows expected to be generated by the asset or asset group. If the undiscounted cash flows are less than the carrying amount of the asset or asset group, an impairment loss is recognized for the amount by which the carrying amount of the asset or asset group exceeds its fair value. |
Research and Development | Research and Development The costs associated with research and development for the purpose of developing and improving new products are expensed as incurred. For the years ended December 31, 2015 , 2014 , and 2013 research and development costs amounted to approximately $7.5 million, $6.3 million , and $5.2 million , respectively. |
Advertising | Advertising Advertising costs are expensed as incurred. Advertising expense for the years ended December 31, 2015 , 2014 , and 2013 was approximately $1.2 million, $1.0 million , and $0.9 million , respectively. |
Shipping and Handling | Shipping and Handling We incur shipping and handling costs in the distribution of products sold that are recorded in cost of sales. Shipping charges that are billed to the customer are recorded in revenues and as an expense in cost of sales. For the years ended December 31, 2015 , 2014 and 2013 shipping and handling fees amounted to approximately $9.6 million, $8.5 million , and $7.9 million , respectively. |
Income Taxes | Income Taxes Income taxes are accounted for under the asset and liability method. The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the book carrying amounts and the tax basis of assets and liabilities. We establish accruals for unrecognized tax positions when it is more likely than not that our tax return positions may not be fully sustained. The Company records a valuation allowance for deferred tax assets when, in the opinion of management, it is more likely than not that deferred tax assets will not be realized. |
Share-Based Compensation | Share-Based Compensation The Company recognizes expense for its share-based compensation based on the fair value of the awards that are granted. The Company’s share-based compensation plans provide for the granting of stock options and restricted stock. The fair values of stock options are estimated at the date of grant using the Black-Scholes-Merton option valuation model. The use of the Black-Scholes-Merton option valuation model requires the input of subjective assumptions. Measured compensation cost, net of estimated forfeitures, is recognized ratably over the vesting period of the related share-based compensation award. Forfeitures are estimated based on the Company's historical experience. The fair value of restricted stock awards is determined based on the market value of the Company’s shares on the grant date and the compensation expense is recognized on a straight-line basis during the service period of the respective grant. |
Financial Derivatives | Derivative Instruments In the course of normal operations, the Company occasionally enters into contracts such as forward priced physical contracts for the purchase of raw materials that qualify for and are designated as normal purchase or normal sale contracts. Such contracts are exempted from the fair value accounting requirements and are accounted for at the time product is purchased or sold under the related contract. The Company does not engage in speculative transactions, nor does the Company hold or issue financial instruments for trading purposes. |
Revenue Recognition | Revenue Recognition We recognize revenues from sales of products when title and risk of ownership pass to the customer. Final sales prices are fixed and based on purchase orders. Sales allowances and customer incentives are treated as reductions to sales and are provided for based on historical experiences and current estimates. Sales of our products are moderately seasonal with the peak period being July - November of each year. In addition, the Company presents revenues net of sales tax and net of certain payments to our independent manufacturer representatives (“Representatives”). Representatives are national companies that are in the business of providing HVAC units and other related products and services to customers. The end user customer orders a bundled group of products and services from the Representative and expects the Representative to fulfill the order. Only after the specifications are agreed to by the Representative and the customer, and the decision is made to use an AAON HVAC unit, will we receive notice of the order. We establish the amount we must receive for our HVAC unit (“minimum sales price”), but do not control the total order price which is negotiated by the Representative with the end user customer. We are responsible for billings and collections resulting from all sales transactions, including those initiated by our Representatives. The Representatives submit the total order price to us for invoicing and collection. The total order price includes our minimum sales price and could contain an additional amount which may include both the Representatives’ fee and amounts due for additional products and services required by the customer. These additional products and services may include controls purchased from another manufacturer to operate the unit, start-up services, and curbs for supporting the unit (“Third Party Products”). All are associated with the purchase of a HVAC unit but may be provided by the Representative or another third party. The Company is under no obligation related to Third Party Products. The Representatives’ fee and Third Party Products amounts (“Due to Representatives”) are paid only after all amounts associated with the order are collected from the customer. The Due to Representatives amount is paid only after all amounts associated with the order are collected from the customer. The amount of payments to our representatives was $55.4 million, $59.7 million , and $63.0 million for each of the years ended December 31, 2015 , 2014 , and 2013 , respectively. The Company also sells extended warranties on parts for various lengths of time ranging from six months to 10 years. Revenue for these separately priced warranties is deferred and recognized on a straight-line basis over the separately priced warranty period. |
Insurance Reserves | Insurance Reserves Under the Company’s insurance programs, coverage is obtained for significant liability limits as well as those risks required to be insured by law or contract. It is the policy of the Company to self-insure a portion of certain expected losses related primarily to workers’ compensation and medical liability. Provisions for losses expected under these programs are recorded based on the Company’s estimates of the aggregate liabilities for the claims incurred. |
Product Warranties | Product Warranties A provision is made for the estimated cost of maintaining product warranties to customers at the time the product is sold based upon historical claims experience by product line. The Company records a liability and an expense for estimated future warranty claims based upon historical experience and management's estimate of the level of future claims. Changes in the estimated amounts recognized in prior years are recorded as an adjustment to the liability and expense in the current year. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Because these estimates and assumptions require significant judgment, actual results could differ from those estimates and could have a significant impact on our results of operations, financial position and cash flows. We reevaluate our estimates and assumptions as needed, but at a minimum on a quarterly basis. The most significant estimates include, but are not limited to, the allowance for doubtful accounts, inventory reserves, warranty accrual, workers compensation accrual, medical insurance accrual, share-based compensation and income taxes. Actual results could differ materially from those estimates. |
New Accounting Pronouncements | Changes to U.S. GAAP are established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASUs") to the FASB's Accounting Standards Codification. We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial statements and notes thereto. |
