Basis of Presentation |
Principles of Consolidation | Principles of Consolidation The condensed consolidated financial statements include the accounts of Simpson Manufacturing Co., Inc. and its subsidiaries (the “Company”). Investments in 50% or less owned affiliates are accounted for using either cost or the equity method. All significant intercompany transactions have been eliminated.
Interim Period Reporting | Interim Period Reporting The accompanying unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and footnotes required by accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These interim statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013 (the “2013 Annual Report”). The unaudited quarterly condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in the opinion of management, contain all adjustments (consisting of only normal recurring adjustments) necessary to state fairly the financial information set forth therein, in accordance with GAAP. The year-end condensed consolidated balance sheet data were derived from audited financial statements, but do not include all disclosures required by GAAP. The Company’s quarterly results fluctuate. As a result, the Company believes the results of operations for the interim periods presented are not necessarily indicative of the results to be expected for any future period.
Revisions | Revisions The Company revised its March 31, 2013, Condensed Consolidated Balance Sheet to classify $5.4 million of indefinite-lived assets as intangible assets, net, that had erroneously been classified as other noncurrent assets. The Condensed Consolidated Statement of Operations for the three months ended March 31, 2013, was revised to reflect $0.3 million of rent income from properties rented to third-parties as an offset to general and administrative expense rather than as net sales as originally reported in error. With this revision, rental incomes are reported, net of related expenses, in general and administrative expense. These revisions were not considered material to the affected periods.
Out-of-Period Adjustment | Out-of-Period Adjustment In the first quarter of 2014, the Company recorded an out-of-period adjustment, which had the effect of increasing gross profit, income from operations and net income by $2.3 million, $2.0 million and $1.3 million, respectively. The adjustment resulted primarily from an over-statement of prior periods’ workers compensation expense, net of cash profit sharing expense, and was not material to the current period or any prior period.
Revenue Recognition | Revenue Recognition The Company recognizes revenue when the earnings process is complete, net of applicable provision for discounts, returns and incentives, whether actual or estimated, based on the Company’s experience. This generally occurs when products are shipped to the customer in accordance with the sales agreement or purchase order, ownership and risk of loss pass to the customer, collectability is reasonably assured and pricing is fixed or determinable. The Company’s general shipping terms are F.O.B. shipping point, where title is transferred and revenue is recognized when the products are shipped to customers. When the Company sells F.O.B. destination point, title is transferred and the Company recognizes revenue on delivery or customer acceptance, depending on terms of the sales agreement. Service sales, representing after-market repair and maintenance, engineering activities, software license sales and services and lease income, though significantly less than 1% of net sales and not material to the condensed consolidated financial statements, are recognized as the services are completed or the software products and services are delivered. If actual costs of sales returns, incentives and discounts were to significantly exceed the recorded estimated allowance, the Company’s sales would be adversely affected.
Net Earnings Per Common Share | Net Earnings Per Common Share Basic earnings per common share is computed based on the weighted-average number of common shares outstanding. Potentially dilutive securities, using the treasury stock method, are included in the diluted per-share calculations for all periods when the effect of their inclusion is dilutive. The following is a reconciliation of basic earnings per common share to diluted earnings per share:

Accounting for Stock-Based Compensation | Accounting for Stock-Based Compensation With the approval of the Company’s stockholders on April 26, 2011, the Company adopted the Simpson Manufacturing Co., Inc. 2011 Incentive Plan (the “2011 Plan”). The 2011 Plan amended and restated in their entirety, and incorporated and superseded, both the Simpson Manufacturing Co., Inc. 1994 Stock Option Plan (the “1994 Plan”), which was principally for the Company’s employees, and the Simpson Manufacturing Co., Inc. 1995 Independent Director Stock Option Plan (the “1995 Plan”), which was for its directors who are not employees. Options previously granted under the 1994 Plan or the 1995 Plan were not affected by the adoption of the 2011 Plan and continue to be governed by the 1994 Plan or the 1995 Plan, respectively. Under the 1994 Plan, the Company could grant incentive stock options and non-qualified stock options. The Company, however, granted only non-qualified stock options under both the 1994 Plan and the 1995 Plan. The Company generally granted options under each of the 1994 Plan and the 1995 Plan once each year. The exercise price per share of each option granted under the 1994 Plan equaled the closing market price per share of the Company’s common stock as reported by the New York Stock Exchange on the day preceding the day that the Compensation and Leadership Development Committee of the Company’s Board of Directors met to approve the grant of the options. The exercise price per share under each option granted under the 1995 Plan was at the fair market value on the date specified in the 1995 Plan. Options vest and expire according to terms established at the grant date. Options granted under the 1994 Plan typically vest evenly over the requisite service period of four years and have a term of seven years. The vesting of options granted under the 1994 Plan will be accelerated if the grantee ceases to be employed by the Company after reaching age 60 or if there is a change in control of the Company. Options granted under the 1995 Plan were fully vested on the date of grant. Shares of common stock issued on exercise of stock options under the 1994 Plan and the 1995 Plan are registered under the Securities Act of 1933. Under the 2011 Plan, the Company may grant incentive stock options, non-qualified stock options, restricted stock and restricted stock units, although the Company currently intends to award primarily restricted stock units and to a lesser extent, if at all, non-qualified stock options. The Company has not awarded, and does not currently intend to award, incentive stock options or restricted stock. Under the 2011 Plan, no more than 16.3 million shares of the Company’s common stock may be issued (including shares already issued) pursuant to all awards under the 2011 Plan, including on exercise of options previously granted under the 1994 Plan and the 1995 Plan. Shares of common stock to be issued pursuant to the 2011 Plan are registered under the Securities Act of 1933. The following table represents the Company’s stock option and restricted stock unit activity for the three months ended March 31, 2014 and 2013:
|  | Three Months Ended March 31, |
(in thousands) |  | 2014 |  | 2013 |
Stock-based compensation expense recognized in operating expenses |  | $ | 2,476 |  | $ | 2,879 |
Tax benefit of stock-based compensation expense in provision for income taxes |  | 910 |  | 1,048 |
Stock-based compensation expense, net of tax |  | $ | 1,566 |  | $ | 1,831 |
Fair value of shares vested |  | $ | 2,379 |  | $ | 2,813 |
Proceeds to the Company from the exercise of stock-based compensation |  | $ | 1,769 |  | $ | 496 |
Tax effect from exercise of stock-based compensation, including shortfall tax benefits |  | $ | (135 | ) | $ | (1,843 | )
|  | At March 31, |
(in thousands) |  | 2014 |  | 2013 |
Stock-based compensation cost capitalized in inventory |  | $ | 459 |  | $ | 361 |
The amounts included in cost of sales, research and development and other engineering, selling, or general and administrative expense depend on the job functions performed by the employees to whom the stock options and restricted stock units were awarded. The assumptions used to calculate the fair value of restricted stock units awarded are evaluated and revised, as necessary, to reflect market conditions and the Company’s experience.
Fair Value of Financial Instruments | Fair Value of Financial Instruments The “Fair Value Measurements and Disclosures” topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification™ (“ASC”) establishes a valuation hierarchy for disclosure of the inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The Company’s investments consisted of only United States Treasury securities and money market funds, which are the Company’s primary financial instruments, maintained in cash equivalents and carried at cost, approximating fair value, based on Level 1 inputs. The balance of the Company’s primary financial instruments was as follows:
|  | At March 31, |  | At December 31 |
(in thousands) |  | 2014 |  | 2013 |  | 2013 |
Financial instruments |  | $ | 99,235 |  | $ | 59,074 |  | $ | 117,571 |
The carrying amounts of trade accounts receivable, accounts payable and accrued liabilities approximate fair value due to the short-term nature of these instruments. The fair value of the Company’s contingent consideration related to acquisitions is classified as Level 3 within the fair value hierarchy and is based on the Company’s unobserved inputs and assumptions, which are used to measure the liabilities at fair value.
Income Taxes | Income Taxes The Company uses an estimated annual effective tax rate to measure the tax benefit or tax expense recognized in each interim period. The effective tax rate was lower in the first quarter of 2014 than in the first quarter of 2013, primarily due to reduced first quarter 2014 operating losses in the Europe and Asia/Pacific segments, for which no tax benefit was recorded. The following table presents the Company’s effective tax rates and income tax expense for the three months ended March 31, 2014 and 2013:
|  | Three Months Ended March 31, |
(in thousands, except percentages) |  | 2014 |  | 2013 |
Effective tax rate |  | 38.6 | % | 47.0 | %
Provision for income taxes |  | $ | 7,604 |  | $ | 4,256 |
Acquisitions | Acquisitions In February 2013, the Company purchased certain assets relating to the TJ® ShearBrace (“ShearBrace”) product line of Weyerhaeuser NR Company (“Weyerhaeuser”) for $5.3 million in cash. The ShearBrace is a line of pre-fabricated shearwalls that complements the Company’s Strong-Wall shearwall, and is sold throughout North America. The Company’s measurement of assets acquired included goodwill of $0.9 million that has been assigned to the North America segment, and intangible assets of $3.6 million, both of which are subject to tax-deductible amortization. Net tangible assets consisting of inventory and equipment accounted for the balance of the purchase price. The weighted-average amortization period for the intangible assets is 11.3 years. In November 2013, the Company purchased certain assets related to a connector product line from Bierbach GmbH & Co. KG (“Bierbach”), a Germany corporation, for $1.2 million in cash and a contingent liability of $0.8 million. Bierbach manufactured and sold a line of connectors, primarily in Germany. The Company’s provisional measurement of assets acquired included goodwill of $0.7 million, which was assigned to the Europe segment, and intangible assets of $0.6 million, both of which are subject to tax-deductible amortization. Net tangible assets consisting of inventory and tooling accounted for the balance of the purchase price. In the first quarter of 2014, the Company paid $1.1 million in deferred consideration and $0.2 million in contingent consideration related to the acquisition of S&P Clever Reinforcement Company AG and S&P Clever International AG (collectively, “S&P Clever”). The remaining deferred and contingent consideration of $1.5 million is payable in the first quarter of 2015. Under the business combinations topic of the FASB ASC, the Company accounted for these acquisitions as business combinations and ascribed acquisition-date fair values to the acquired assets. Provisional fair value measurements were made in the first and fourth quarters of 2013 for the acquired assets of ShearBrace and Bierbach, respectively. Adjustments to those measurements may be made in subsequent periods, up to one year from the acquisition date, as information necessary to complete the analysis is obtained. Fair value of intangible assets was based on Level 3 inputs. The Company has completed the measurement process for ShearBrace assets and expects the measurement process for the Bierbach acquisition to be finalized within a year of its acquisition date. Pro-forma financial information is not presented as it would not be materially different from the information presented in the Condensed Consolidated Statements of Operations.
Recently Issued Accounting Standards | Recently Issued Accounting Standards In April 2014, the FASB issued ASC Update No. 2014-08 (Topic 205 and Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This ASC update modifies the definition of discontinued operations by limiting discontinued operations reporting to disposals of components of an entity that represent strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. This update also requires additional financial statement disclosures about discontinued operations, as well as disposal of an individually significant component of an entity that does not qualify for discontinued operations presentation. The updated guidance is effective prospectively for years beginning on or after December 15, 2014. The Company expects that the adoption of ASC Update 2014-08 will not materially affect its financial position or results of operations. Other recent authoritative guidance issued by the FASB (including technical corrections to the ASC), the American Institute of Certified Public Accountants and the Securities and Exchange Commission did not or is not expected to have a material effect on the Company’s consolidated financial statements.
