Summary of Significant Accounting Policies
1. Summary of Significant Accounting Policies

 

Organization

 

Sturm, Ruger & Company, Inc. (the “Company”) is principally engaged in the design, manufacture, and sale of firearms to domestic customers. Virtually all of the Company's total sales for the year ended December 31, 2014 were from the firearms segment and export sales represented approximately 4% of firearms sales. The Company's design and manufacturing operations are located in the United States and almost all product content is domestic. The Company's firearms are sold through a select number of independent wholesale distributors principally to the commercial sporting market.

 

The Company manufactures investment castings made from steel alloys and metal injection molding ("MIM") parts for internal use in its firearms and utilizes available capacity to manufacture and sell investment castings and MIM parts  to unaffiliated, third-party customers. Castings were less than 1% of the Company's total sales for the year ended December 31, 2014.

 

Preparation of Financial Statements

 

The Company follows United States generally accepted accounting principles (“GAAP”). 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 liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

 

The significant accounting policies described below, together with the notes that follow, are an integral part of the Financial Statements.

 

Principles of Consolidation


The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany accounts and transactions have been eliminated.


Revenue Recognition

 

Substantially all product sales are sold FOB (free on board) shipping point. Revenue is recognized when product is shipped and the customer takes ownership and assumes the risk of loss. Accruals are made for sales discounts and incentives based on the Company's experience. The Company accounts for cash sales discounts as a reduction in sales and sales incentives as a charge to selling expense. Amounts billed to customers for shipping and handling fees are included in net sales and costs incurred by the Company for the delivery of goods are classified as selling expenses. Federal excise taxes are excluded from net sales.

 

Cash and Cash Equivalents

 

The Company considers interest-bearing deposits with financial institutions with remaining maturities of three months or less at the time of acquisition to be cash equivalents.

 

Accounts Receivable

 

The Company establishes an allowance for doubtful accounts based on the credit worthiness of its customers and historical experience. While the Company uses the best information available to make its evaluation, future adjustments to the allowance for doubtful accounts may be necessary if there are significant changes in economic and industry conditions or any other factors considered in the Company's evaluation. Bad debt expense has been immaterial during each of the last three years.

 

Inventories

 

Substantially all of the Company's inventories are valued at the lower of cost, principally determined by the last-in, first-out (LIFO) method, or market. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead.

 

Property, Plant, and Equipment

 

Property, plant, and equipment are carried at cost. Depreciation is computed over useful lives using the straight-line and declining balance methods predominately over 15 years for buildings, 7 years for machinery and equipment and 3 years for tools and dies. When assets are retired, sold or otherwise disposed of, their gross carrying values and related accumulated depreciation are removed from the accounts and a gain or loss on such disposals is recognized when appropriate.

 

Maintenance and repairs are charged to operations; replacements and improvements are capitalized.

 

Long-lived Assets

 

The Company evaluates the carrying value of long-lived assets to be held and used when events or changes in circumstances indicate the carrying value may not be recoverable. In performing this review, the carrying value of the assets is compared to the projected undiscounted cash flows to be generated from the assets. If the sum of the undiscounted expected future cash flows is less than the carrying value of the assets, the assets are considered to be impaired. Impairment losses are measured as the amount by which the carrying value of the assets exceeds their fair value. The Company bases fair value of the assets on quoted market prices if available or, if not available, quoted market prices of similar assets. Where quoted market prices are not available, the Company estimates fair value using the estimated future cash flows generated by the assets discounted at a rate commensurate with the risks associated with the recovery of the assets.

  

Income Taxes

 

Income taxes are accounted for using the asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of “temporary differences” by applying enacted statutory rates applicable to future years to temporary differences between the financial statement carrying amounts and the tax basis of the Company's assets and liabilities.

 

Product Liability

 

The Company provides for product liability claims including estimated legal costs to be incurred defending such claims. The provision for product liability claims is charged to cost of products sold.

 

Advertising Costs

 

The Company expenses advertising costs as incurred. Advertising expenses for 2014, 2013, and 2012, were $3.6 million, $3.2 million, and $3.4 million, respectively.

 

Shipping Costs

 

Costs incurred related to the shipment of products are included in selling expense. Such costs totaled $7.1 million, $6.8 million, and $5.6 million in 2014, 2013, and 2012, respectively.

 

Research and Development

 

In 2014, 2013, and 2012, the Company spent approximately $10.0 million, $6.2 million, and $5.9 million, respectively, on research and development activities relating to new products and the improvement of existing products. These costs are expensed as incurred.

 

Earnings per Share

 

Basic earnings per share is based upon the weighted-average number of shares of common stock outstanding during the year. Diluted earnings per share reflect the impact of options, restricted stock units, and deferred stock outstanding using the treasury stock method.

In 2013, the Company revised its estimate of the useful life of machinery and equipment from 10 to 7 years. This change, which became effective December 31, 2013, resulted in increased depreciation expense of $7.1 million and $0.7 million for 2014 and 2013, respectively. The Company estimates that this change will increase depreciation expense for the machinery and equipment that was on hand at December 31, 2013 by approximately $3 million in 2015.

  8. Employee Benefit Plans

In the fourth quarter of 2014, the Company completed the migration of its retirement benefits from defined-benefit pension plans to defined-contribution retirement plans, utilizing its 401(k) plan.

The Company previously sponsored two qualified defined-benefit pension plans that covered substantially all employees. In 2007, the Company amended its hourly and salaried defined-benefit pension plans so that employees no longer accrued benefits under them. This action “froze” the benefits for all employees and prevented future hires from joining the plans. A third defined-benefit pension plan was non-qualified and covered certain executive officers of the Company.

The Company sponsors a defined-contribution 401(k) plan that covers substantially all employees. The Company matches employee contributions to their 401(k) accounts using the “safe harbor” guidelines provided in the Internal Revenue Code. In addition, the Company provides discretionary supplemental contributions to substantially all employees' individual 401(k) accounts.

Defined-Benefit Plans

 

In December 2014 the Company terminated its defined benefit pension plans and settled all obligations to employees. As a result of the termination of the plans, the Company recognized a one-time charge to expense of $41.0  million in the fourth quarter of 2014, primarily comprised of the recognition of previously deferred actuarial losses.

Active employees, all of whom were 100 percent vested in their pension benefits, were given the option of rolling the actuarially determined present value of their benefits into their 401(k) accounts, receiving deferred annuity contracts issued by an insurance carrier, or receiving a lump sum payment.

The Company contributed $7.5 million to the frozen pension plans in 2014 in order to fully fund the settlement, representing the shortfall of the existing pension fund assets on the termination date to the settlement value. The Company contributed $3 million and $3 million to these frozen pension plans in 2013 and 2012, respectively, which satisfied the required minimum contribution in each year.  Since the plans have been fully funded and settled, no further cash contributions will be required in future years.

The measurement dates of the assets and liabilities of all plans presented for 2014 and 2013 were December 31, 2014 and December 31, 2013, respectively.

In conjunction with the termination and settlement of the defined-benefit pension plans, the additional minimum pension liability was fully recognized. The Company recorded an adjustment to the additional minimum pension liability, net of tax, which increased comprehensive income by $10.2 million in 2013, and decreased comprehensive income by $2.1 million in 2012, respectively.

 

Plan Assets

 

As a result of the termination and settlement of the defined-benefit pension plans, there are no plan assets as of December 31, 2014. The following table sets forth the defined-benefit plans' assets at fair value as of December 31, 2013:

Defined-Contribution Plans

 

Prior to 2007, the Company also sponsored two qualified defined-contribution plans that covered substantially all of its hourly and salaried employees. Effective January 1, 2007, the qualified defined-contribution plans were merged into a single 401(k) plan. Under the terms of the 401(k) plan, the Company matches a certain portion of employee contributions. Expenses related to matching employee contributions to the 401(k) plan were $3.2 million, $3.0 million, and $2.3 million in 2014, 2013, and 2012, respectively.

 

Additionally, in 2014, 2013, and 2012 the Company provided discretionary supplemental contributions to the individual 401(k) accounts of substantially all employees. Each employee received a supplemental contribution to their account based on a uniform percentage of qualifying compensation established annually. The cost of these supplemental contributions totaled $5.6 million, $4.9 million, and $3.3 million in 2014, 2013, and 2012, respectively.

The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal and state income tax examinations by tax authorities for years before 2010.

 

The federal and state income tax provision consisted of the following:

 

Year ended December 31, 2014     2013     2012  
      Current       Deferred       Current       Deferred       Current       Deferred  
Federal   $ 25,797     $ (10,429   $ 49,022     $ 4,879     $ 34,941     $ (327 )
State     5,019       (1,775     9,202       857       6,635       231  
    $ 30,816     $ (12,204   $ 58,224     $ 5,736     $ 41,576     $ (96 )

 

The effective income tax rate varied from the statutory federal income tax rate as follows:

 

Year ended December 31, 2014     2013     2012  
Statutory federal income tax rate     35.0 %     35.0 %     35.0 %
State income taxes, net of federal tax benefit     3.7       3.7       4.0  
Domestic production activities deduction     (4.6 )     (2.7 )     (3.0 )
Other items     (1.6)       0.5       1.0  
Effective income tax rate     32.5 %     36.5 %     37.0 %

 

Significant components of the Company's deferred tax assets and liabilities are as follows:

 

December 31,   2014     2013  
Deferred tax assets:                
Product liability   $ 289     $ 451  
Employee compensation and benefits     3,621       3,708  
Allowances for doubtful accounts and discounts     2,351       2,558  
Inventories     1,411       932  
Additional minimum pension liability     -       10,905  
Stock-based compensation     4,517       3,672  
Other     1,487       1,853  
Total deferred tax assets     13,676       24,079  
Deferred tax liabilities:                
Pension plans     -       11,310  
Depreciation     14,377       14,311  
Other     387       422  
Total deferred tax liabilities     14,764       26,043  
Net deferred tax (liabilities) assets   $ (1,088 )   $ (1,964 )

 

Changes in deferred tax assets relating to the additional minimum pension liability are not charged to expense and are therefore not included in the deferred tax provision; instead they are charged to other comprehensive income.

 

The Company made income tax payments of approximately $34.0 million, $59.9 million, and $33.0 million, during 2014, 2013, and 2012, respectively. The Company expects to realize its deferred tax assets through tax deductions against future taxable income or carry back against taxes previously paid.

 

The Company does not believe it has included any “uncertain tax positions” in its federal income tax return or any of the state income tax returns it is currently filing. The Company has made an evaluation of the potential impact of additional state taxes being assessed by jurisdictions in which the Company does not currently consider itself liable. The Company does not anticipate that such additional taxes, if any, would result in a material change to its financial position.

11. Earnings Per Share

 

Set forth below is a reconciliation of the numerator and denominator for basic and diluted earnings per share calculations for the periods indicated:

Numerator:                        
Net income   $ 38,628     $ 111,272     $ 70,629  
Denominator:                        
Weighted average number of common shares outstanding – Basic     19,367,928       19,327,394       19,160,849  
Dilutive effect of options and restricted stock units outstanding under the Company's employee compensation plans     469,480       613,324       474,392  
Weighted average number of common shares outstanding – Diluted     19,837,408       19,940,718       19,635,241  

 

The dilutive effect of outstanding options and restricted stock units is calculated using the treasury stock method. There are no anti-dilutive stock options in 2014, 2013, and 2012 because the closing price of the Company's stock on December 31, 2014, 2013, and 2012 exceeded the strike price of all outstanding options on that date.

Compensation Plan [Abstract]  
Compensation Plan
13. Compensation Plans

 

In April 2007, the Company adopted and the shareholders approved the 2007 Stock Incentive Plan (the “2007 SIP”) under which employees, independent contractors, and non-employee directors may be granted stock options, restricted stock, deferred stock awards, restricted stock units (“RSU's”), and stock appreciation rights, any of which may or may not require the achievement of performance objectives. Vesting requirements are determined by the Compensation Committee of the Board of Directors. The Company reserved 2,550,000 shares for issuance under the 2007 SIP. At December 31, 2014, an aggregate of 628,000 shares remain available for grant under the 2007 SIP.

 

Compensation expense related to stock options is recognized based on the grant-date fair value of the awards estimated using the Black-Scholes option pricing model. Compensation expense related to deferred stock, restricted stock, and restricted stock units is recognized based on the grant-date fair value of the Company's common stock. The total stock-based compensation cost included in the Statements of Income was $5.6 million, $5.3 million, and $4.7 million in 2014, 2013, and 2012, respectively.

 

Stock Options

 

There were no stock options granted in 2014 and 2013. In 2012, 9,830 stock options were granted as an equitable adjustment in conjunction with the special dividend declared in the fourth quarter of 2012. For purposes of determining the fair value of stock option awards granted, the Company used the Black-Scholes option pricing model and the assumptions set forth in the table below.

 

    2012  
Dividend yield     2.9 %
Expected volatility     44.2 %
Risk free rate of return     4.0 %
Expected lives     2.9 years  

 

The estimated fair value of options granted is subject to the assumptions made and if the assumptions changed, the estimated fair value amounts could be significantly different.

 

The following table summarizes the stock option activity of the Plans:

At December 31, 2014, the aggregate intrinsic value of all options, including exercisable options, was $1.1 million.

 

Deferred Stock

 

Deferred stock awards vest based on the passage of time or the Company's attainment of performance objectives. Upon vesting, these awards convert one-for-one to common stock.


In 2014, 3,711 deferred stock awards were issued to non-employee directors that will vest in April 2015 and 7,002 deferred stock awards were issued to non-employee directors that will vest in April 2017.


In 2013, 4,430 deferred stock awards were issued to non-employee directors that will vest in April 2014 and 5,952 deferred stock awards were issued to non-employee directors that will vest in April 2016.

 

In 2012, 4,542 deferred stock awards were issued to non-employee directors that will vest in April 2013 and 6,102 deferred stock awards were issued to non-employee directors that will vest in April 2015.

 

Compensation expense related to these awards is amortized ratably over the vesting period. Compensation expense related to these awards was $0.6 million, $0.5 million and $0.5 million in 2014, 2013, and 2012, respectively.

 

At December 31, 2014, there was $0.6 million of unrecognized compensation cost related to deferred stock that is expected to be recognized over a period of three years.

 

Restricted Stock Units

 

Beginning in the second quarter of 2009, the Company began granting restricted stock units in lieu of incentive stock options to senior employees. These RSU's have a vesting “double trigger.” The vesting of these RSU's is dependent on the achievement of corporate objectives established by the Compensation Committee of the Board of Directors and the passage of time.


During 2014, 59,000 restricted stock units were issued. Compensation costs related to these restricted stock units was $3.8 million, of which $1.0 million was recognized in 2014. The remaining costs will be recognized ratably over the remaining period required before the units vest, which is 27 months.

 

During 2013, 32,000 restricted stock units were issued. Compensation costs related to these restricted stock units was $1.8 million, of which $0.6 and $0.5 million was recognized in 2014 and 2013, respectively. The remaining costs will be recognized ratably over the remaining period required before the units vest, which is 15 months.

During 2012, 139,000 restricted stock units were issued. Compensation costs related to these restricted stock units was $6.2 million, of which $1.5 million, $1.5 million and $1.2 million was recognized in 2014, 2013 and 2012, respectively. The remaining costs will be recognized ratably over the remaining period required before the units vest, which ranges from one to two years.

 

At December 31, 2014, there was $7.2 million of unrecognized compensation cost related to restricted stock units that is expected to be recognized over a period of 2.3 years.

Operating Segment Information
  14. Operating Segment Information

 

The Company has two reportable operating segments: firearms and castings. The firearms segment manufactures and sells rifles, pistols, revolvers, and shotguns principally to a number of federally-licensed, independent wholesale distributors primarily located in the United States. The castings segment manufactures and sells steel investment castings and metal injection molding parts.

 

Corporate segment income relates to interest income on short-term investments, the sale of non-operating assets, and other non-operating activities. Corporate segment assets consist of cash and short-term investments and other non-operating assets.

 

The Company evaluates performance and allocates resources, in part, based on profit and loss before taxes. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies (see Note 1). Intersegment sales are recorded at the Company's cost plus a fixed profit percentage.

Contingent Liabilities
16. Contingent Liabilities

 

As of December 31, 2014, the Company was a defendant in approximately three (3) lawsuits and is aware of certain other such claims. The lawsuits fall into three general categories, traditional products liability, municipal litigation, and commercial litigation, discussed in turn below.

 

Traditional Product Liability Litigation

 

One of the three lawsuits mentioned above involve claims for damages related to allegedly defective product design and/or manufacture. These types of lawsuits stem from a specific incident of personal injury and are based on traditional product liability theories such as strict liability, negligence and/or breach of warranty.

 

The Company management believes that the allegations in these cases are unfounded, and that the incidents were caused by the negligence and/or misuse of the firearms by third-parties or the claimant, and that there should be no  recovery against the Company.

 

Municipal Litigation

 

Municipal litigation generally includes those cases brought by cities or other governmental entities against firearms manufacturers, distributors and retailers seeking to recover damages allegedly arising out of the misuse of firearms by third-parties.

 

There is only one remaining lawsuit of this type, filed by the City of Gary in Indiana State Court, over fifteen years ago. The complaint in that case seeks damages, among other things, for the costs of medical care, police and emergency services, public health services, and other services as well as punitive damages. In addition, nuisance abatement and/or injunctive relief is sought to change the design, manufacture, marketing and distribution practices of the various defendants. The suit alleges, among other claims, negligence in the design of products, public nuisance, negligent distribution and marketing, negligence per se and deceptive advertising. The case does not allege a specific injury to a specific individual as a result of the misuse or use of any of the Company's products.

 

After a long procedural history, the case was scheduled for trial on June 15, 2009. The case was not tried on that date and no subsequent scheduling order has been entered. There has been no activity since that time.

 

Commercial Litigation

 

From time to time, the Company may be involved in commercial disputes that result in litigation. These disputes run the gamut and may involve intellectual property, real property, supply or distribution agreements, contract disputes, or other, general commercial matters. As of December 31, 2014, the Company was involved in one such lawsuit and is aware of certain other such claims.

 

Summary of Claimed Damages and Explanation of Product Liability Accruals

 

Punitive damages, as well as compensatory damages, are demanded in certain of the lawsuits and claims. Aggregate claimed amounts presently exceed product liability accruals and applicable insurance coverage. For product liability claims made after July 10, 2000, coverage is provided on an annual basis for losses exceeding $5 million per claim, or an aggregate maximum loss of $10 million annually, except for certain new claims which might be brought by governments or municipalities after July 10, 2000, which are excluded from coverage.

 

The Company management monitors the status of known claims and the product liability accrual, which includes amounts for asserted and unasserted claims. While it is not possible to forecast the outcome of litigation or the timing of costs, in the opinion of management, after consultation with special and corporate counsel, it is not probable and is unlikely that litigation, including punitive damage claims, will have a material adverse effect on the financial position of the Company, but may have a material impact on the Company's financial results for a particular period.

 

Product liability claim payments are made when appropriate if, as, and when claimants and the Company reach agreement upon an amount to finally resolve all claims. Legal costs are paid as the lawsuits and claims develop, the timing of which may vary greatly from case to case. A time schedule cannot be determined in advance with any reliability concerning when payments will be made in any given case.

 

Provision is made for product liability claims based upon many factors related to the severity of the alleged injury and potential liability exposure, based upon prior claim experience. Because the Company's experience in defending these lawsuits and claims is that unfavorable outcomes are typically not probable or estimable, only in rare cases is an accrual established for such costs. In most cases, an accrual is established only for estimated legal defense costs. Product liability accruals are periodically reviewed to reflect then-current estimates of possible liabilities and expenses incurred to date and reasonably anticipated in the future. Threatened product liability claims are reflected in the Company's product liability accrual on the same basis as actual claims; i.e., an accrual is made for reasonably anticipated possible liability and claims-handling expenses on an ongoing basis.

 

A range of reasonably possible loss relating to unfavorable outcomes cannot be made. However, in product liability cases in which a dollar amount of damages is claimed, the amount of damages claimed, which totaled $0.0 million and $0.0 million at December 31, 2014 and 2013, respectively, are set forth as an indication of possible maximum liability that the Company might be required to incur in these cases (regardless of the likelihood or reasonable probability of any or all of this amount being awarded to claimants) as a result of adverse judgments that are sustained on appeal.

 

As of December 31, 2014 and 2013, the Company was a defendant in 2 and 4 lawsuits, respectively, involving its products and is aware of other such claims. During 2014 and 2013, respectively, 0 and 2 claims were filed against the Company, 2 and 0 claims were settled, and no claims were dismissed in either year.

 

The Company's product liability expense was $0.8 million in 2014, $1.3 million in 2013, and $0.2 million in 2012. This expense includes the cost of outside legal fees, insurance, and other expenses incurred in the management and defense of product liability matters.

 

A roll-forward of the product liability reserve and detail of product liability expense for the three years ended December 31, 2014 follows:

Notes

 

(a)
The beginning and ending liability balances represent accrued legal fees only. Settlements and administrative costs are expensed as incurred. Only in rare instances is an accrual established for settlements.

 

(b)
The expense accrued in the liability is for legal fees only. In 2012, the costs incurred related to cases that were settled or dismissed were less than the amounts accrued for these cases in prior years.

 

(c)
Legal fees represent payments to outside counsel related to product liability matters.

 

(d)
Settlements represent payments made to plaintiffs or allegedly injured parties in exchange for a full and complete release of liability.

 

(e)
Insurance expense represents the cost of insurance premiums.

 

There were no insurance recoveries during any of the above years.

Organization

 

Sturm, Ruger & Company, Inc. (the “Company”) is principally engaged in the design, manufacture, and sale of firearms to domestic customers. Virtually all of the Company's total sales for the year ended December 31, 2014 were from the firearms segment and export sales represented approximately 4% of firearms sales. The Company's design and manufacturing operations are located in the United States and almost all product content is domestic. The Company's firearms are sold through a select number of independent wholesale distributors principally to the commercial sporting market.

 

The Company manufactures investment castings made from steel alloys and metal injection molding ("MIM") parts for internal use in its firearms and utilizes available capacity to manufacture and sell investment castings and MIM parts  to unaffiliated, third-party customers. Castings were less than 1% of the Company's total sales for the year ended December 31, 2014.

Preparation of Financial Statements

Preparation of Financial Statements

 

The Company follows United States generally accepted accounting principles (“GAAP”). 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 liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

 

The significant accounting policies described below, together with the notes that follow, are an integral part of the Financial Statements.

Principles of Consolidation

Principles of Consolidation


The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. All significant intercompany accounts and transactions have been eliminated.

Revenue Recognition

Revenue Recognition

 

Substantially all product sales are sold FOB (free on board) shipping point. Revenue is recognized when product is shipped and the customer takes ownership and assumes the risk of loss. Accruals are made for sales discounts and incentives based on the Company's experience. The Company accounts for cash sales discounts as a reduction in sales and sales incentives as a charge to selling expense. Amounts billed to customers for shipping and handling fees are included in net sales and costs incurred by the Company for the delivery of goods are classified as selling expenses. Federal excise taxes are excluded from net sales.

Cash and Cash Equivalents

Cash and Cash Equivalents

 

The Company considers interest-bearing deposits with financial institutions with remaining maturities of three months or less at the time of acquisition to be cash equivalents.

Accounts Receivable

Accounts Receivable

 

The Company establishes an allowance for doubtful accounts based on the credit worthiness of its customers and historical experience. While the Company uses the best information available to make its evaluation, future adjustments to the allowance for doubtful accounts may be necessary if there are significant changes in economic and industry conditions or any other factors considered in the Company's evaluation. Bad debt expense has been immaterial during each of the last three years.

Inventories

Inventories

 

Substantially all of the Company's inventories are valued at the lower of cost, principally determined by the last-in, first-out (LIFO) method, or market. Elements of cost in inventories include raw materials, direct labor and manufacturing overhead.

Property, Plant, and Equipment

Property, Plant, and Equipment

 

Property, plant, and equipment are carried at cost. Depreciation is computed over useful lives using the straight-line and declining balance methods predominately over 15 years for buildings, 7 years for machinery and equipment and 3 years for tools and dies. When assets are retired, sold or otherwise disposed of, their gross carrying values and related accumulated depreciation are removed from the accounts and a gain or loss on such disposals is recognized when appropriate.

 

Maintenance and repairs are charged to operations; replacements and improvements are capitalized.

Long-lived Assets

Long-lived Assets

 

The Company evaluates the carrying value of long-lived assets to be held and used when events or changes in circumstances indicate the carrying value may not be recoverable. In performing this review, the carrying value of the assets is compared to the projected undiscounted cash flows to be generated from the assets. If the sum of the undiscounted expected future cash flows is less than the carrying value of the assets, the assets are considered to be impaired. Impairment losses are measured as the amount by which the carrying value of the assets exceeds their fair value. The Company bases fair value of the assets on quoted market prices if available or, if not available, quoted market prices of similar assets. Where quoted market prices are not available, the Company estimates fair value using the estimated future cash flows generated by the assets discounted at a rate commensurate with the risks associated with the recovery of the assets.

Income Taxes

Income Taxes

 

Income taxes are accounted for using the asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of “temporary differences” by applying enacted statutory rates applicable to future years to temporary differences between the financial statement carrying amounts and the tax basis of the Company's assets and liabilities.

Product Liability

Product Liability

 

The Company provides for product liability claims including estimated legal costs to be incurred defending such claims. The provision for product liability claims is charged to cost of products sold.

Advertising Costs

Advertising Costs

 

The Company expenses advertising costs as incurred. Advertising expenses for 2014, 2013, and 2012, were $3.6 million, $3.2 million, and $3.4 million, respectively.

Shipping Costs

Shipping Costs

 

Costs incurred related to the shipment of products are included in selling expense. Such costs totaled $7.1 million, $6.8 million, and $5.6 million in 2014, 2013, and 2012, respectively.

Research and Development

Research and Development

 

In 2014, 2013, and 2012, the Company spent approximately $10.0 million, $6.2 million, and $5.9 million, respectively, on research and development activities relating to new products and the improvement of existing products. These costs are expensed as incurred.

Earnings per Share

Earnings per Share

 

Basic earnings per share is based upon the weighted-average number of shares of common stock outstanding during the year. Diluted earnings per share reflect the impact of options, restricted stock units, and deferred stock outstanding using the treasury stock method.
