Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

1.	Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Additionally, the condensed consolidated financial statements should be read in conjunction with Item 2 of Management's Discussion and Analysis of Financial Condition and Results of Operations, included in this Form 10-Q. Operating results for the 13-week and 39-week periods ended September 24, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016.

The condensed consolidated balance sheet at December 26, 2015 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 26, 2015.

The Company’s fiscal year is based on a 52-53 week period ending on the last Saturday of the calendar year. Therefore the financial results of certain 53-week fiscal years, and the associated 14-week quarters, will not be exactly comparable to the prior and subsequent 52-week fiscal years and the associated 13-week quarters. The quarters ended September 24, 2016 and September 26, 2015 both contain operating results for 13 weeks. The Company’s fiscal quarter and year ending December 31, 2016 will contain operating results for 14 weeks and 53 weeks, respectively.

At the Company’s Annual General Meeting on June 10, 2016, the Company’s shareholders approved the cancellation of 10,000 registered shares of the Company held by the Company (the “Formation Shares”) and the reduction in par value of each share of the Company from CHF 10 to CHF 0.10 and the amendment of the Company’s Articles of Association to effect a corresponding share capital reduction. The Company completed the cancellation of the Formation Shares and the reduction in par value of each share and the corresponding reduction of the Company’s issued share capital during the quarter ended September 24, 2016. The related reduction of share capital and corresponding increase to additional paid-in capital is reflected within the condensed consolidated balance sheet as of September 24, 2016.

Segment Reporting [Abstract]

Segment Information

4.

Segment Information

The Company has identified five reportable segments – Auto, Aviation, Marine, Outdoor and Fitness. The Company’s Chief Operating Decision Maker (CODM) assesses segment performance and allocates resources to each segment individually.

Net sales, gross profit, and operating income for each of the Company’s reportable segments are presented below. In 2016 the Company moved action camera related revenue and expenses from the Outdoor segment to the Auto segment, allowing for alignment and synergies with other camera-based efforts occurring within the Auto segment. The overall impact of the move was immaterial. However, action camera related operating results for the 13-weeks and 39-weeks ended September 26, 2015 have been recast to conform to the current year presentation.

Warranty Reserves

5.	Warranty Reserves

The Company’s products sold are generally covered by a warranty for periods ranging from one to two years. The Company’s estimate of costs to service its warranty obligations are based on historical experience and expectation of future conditions and are recorded as a liability on the balance sheet. The following reconciliation provides an illustration of changes in the aggregate warranty reserve.

Commitments and Contingencies

Commitments and Contingencies

The Company is party to certain commitments, which include purchases of raw materials, advertising expenditures, investments in certain low income housing tax credit projects, and other indirect purchases in connection with conducting our business. The aggregate amount of purchase orders and other commitments open as of September 24, 2016 was approximately $277,041. We cannot determine the aggregate amount of such purchase orders that represent contractual obligations because purchase orders may represent authorizations to purchase rather than binding agreements. Our purchase orders are based on our current needs and are typically fulfilled within short periods of time.

In the normal course of business, the Company and its subsidiaries are parties to various legal claims, investigations and complaints, including matters alleging patent infringement and other intellectual property claims. The Company evaluates, on a quarterly basis, developments in legal proceedings, investigations or claims that could affect the amount of any accrual or disclosure. The assessment regarding whether a loss is probable or a reasonable possibility, and whether the loss or a range of loss is estimable, often involves a series of complex judgments about future events.

Management of the Company currently does not believe there is at least a reasonable possibility the Company may have incurred a material loss, or a material loss in excess of recorded accruals, with respect to loss contingencies individually and in the aggregate, for the fiscal quarter ended September 24, 2016. The results of legal proceedings, investigations and claims, however, cannot be predicted with certainty. Although management considers the likelihood to be remote, an adverse resolution of one or more of such matters in excess of management’s expectations could have a material adverse effect on the Company’s results of operations in a particular quarter or fiscal year.

The Company settled or resolved certain matters during the fiscal quarter ended September 24, 2016 that did not individually or in the aggregate have a material impact on the Company’s financial condition or results of operations.

Income Taxes

7.	Income Taxes

The Company’s income tax expense decreased from $45,592 to $24,711 for the 13-week period ended September 24, 2016, compared to the 13-week period ended September 26, 2015. The effective tax rate decreased to 16.5% in the third quarter of 2016, compared to 27.6% in the third quarter of 2015 primarily due to shifts in the projected income mix by jurisdiction during the third quarter of 2016 compared to the third quarter of 2015. The decrease in the effective tax rate was also a result of the permanent extension of the U.S. research and development tax credit legislation, which had not yet been extended in the third quarter of 2015.

The Company’s income tax expense decreased from $90,800 to $86,904 for the first three quarters of 2016, compared to the first three quarters of 2015. The effective tax rate decreased to 18.8% for the first three quarters of 2016, compared to 21.9% in the first three quarters of 2015 primarily due to shifts in the projected income mix by jurisdiction for 2016 compared to the projection at third quarter of 2015. The decrease in the effective tax rate was also a result of the permanent extension of the U.S. research and development tax credit legislation, which had not yet been extended in the third quarter of 2015.

Marketable Securities

8.	Marketable Securities

The Financial Accounting Standards Board ("FASB") ASC topic entitled Fair Value Measurements and Disclosures defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The accounting guidance classifies the inputs used to measure fair value into the following hierarchy:

Level 1

Unadjusted quoted prices in active markets for the identical asset or liability

Level 2

Observable inputs for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability

Level 3

Unobservable inputs for the asset or liability

The Company endeavors to utilize the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Valuation is based on prices obtained from an independent pricing vendor using both market and income approaches. The primary inputs to the valuation include quoted prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields, and credit spreads.

The method described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Available-for-sale securities measured at estimated fair value on a recurring basis are summarized below:

(1)

Represents impairment not related to credit for those investment securities that have been determined to be other-than-temporarily impaired.

(2)

Represents unrealized losses on investment securities that have not been determined to be other-than-temporarily impaired.

The Company’s investment policy requires investments to be rated A or better with the objective of minimizing the potential risk of principal loss. The fair value of the securities varies from period to period due to changes in interest rates, in the performance of the underlying collateral and in the credit performance of the underlying issuer, among other factors. The Company does not intend to sell the securities that have a material unrealized loss shown in the table above and it is not more likely than not that the Company will be required to sell the investment before recovery of their amortized costs bases, which may be maturity.

The Company recognizes the credit component of other-than-temporary impairments of debt securities in "Other Income" and the noncredit component in "Other comprehensive income (loss)" for those securities that we do not intend to sell and for which it is not more likely than not that we will be required to sell before recovery. During 2015 and the 39-week period ending September 24, 2016, the Company did not record any material impairment charges on its outstanding securities.

The amortized cost and estimated fair value of the securities at an unrealized loss position at September 24, 2016 were $692,047 and $685,131 respectively. Approximately 34.7% of securities in our portfolio were at an unrealized loss position at September 24, 2016. We have the ability to hold these securities until maturity or their value is recovered. We do not consider these unrealized losses to be other than temporary credit losses because there has been no material deterioration in credit quality and no change in the cash flows of the underlying securities. We do not intend to sell the securities and it is not more likely than not that we will be required to sell the securities; therefore, no material impairment has been recorded in the accompanying condensed consolidated statement of income.

The cost of securities sold is based on the specific identification method.

The following tables display additional information regarding gross unrealized losses and fair value by major security type for available-for-sale securities in an unrealized loss position as of September 24, 2016 and December 26, 2015:

Accounting Changes and Error Corrections [Abstract]

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes previous revenue recognition guidance. ASU 2014-09 requires that a company will recognize revenue at an amount that reflects the consideration to which the company expects to be entitled in exchange for transferring goods or services to a customer. The new standard may be applied retrospectively to each prior period presented or in a modified retrospective approach in which the cumulative effect will be recognized as of the date of adoption. Additional updates to Topic 606 issued by the FASB in 2015 and 2016 include the following:

•

ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU 2015-14”), which defers the effective date of the new guidance such that the new provisions will now be required for fiscal years, and interim periods within those years, beginning after December 15, 2017

•

ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (“ASU 2016-08”), which clarifies the implementation guidance on principal versus agent considerations (reporting revenue gross versus net).

•

ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing (“ASU 2016-10”), which clarifies the implementation guidance on identifying performance obligations and classifying licensing arrangements

•

ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”), which clarifies the implementation guidance in a number of other areas.

The Company is currently evaluating the impact of adopting the new revenue standards on its consolidated financial statements.

In January 2016, the FASB issued Accounting Standards Update No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). The standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company is currently evaluating the impact of adopting the new standard on its consolidated financial statements.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. ASU 2016-02 requires lessees to present a right-of-use asset and a corresponding lease liability on the balance sheet. Lessor accounting is substantially unchanged compared to the current accounting guidance. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new standard on its consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which is intended to simplify the accounting for share-based payment awards. The standard includes provisions addressing income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company does not intend to early adopt ASU 2016-09, rather, adoption will occur in the fiscal year ending December 30, 2017. ASU 2016-09 requires that tax effects from stock-based compensation be recognized in the income tax provision, as these amounts are currently recognized in additional paid-in capital. The Company believes this aspect of the standard may have a material effect on the income tax provision within the consolidated statements of income in future periods. Furthermore, under ASU 2016-09, excess income tax benefits from stock-based compensation arrangements are classified as a cash flow from operations, rather than as a cash flow from financing activities. The Company will apply both changes prospectively. The Company is currently unable to reasonably estimate the impact of these changes due to the dependency of these items on the underlying share price of the Company.

In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The standard addresses eight specific cash flow issues with the objective of reducing diversity in practice. ASU 2016-15 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new standard on its consolidated financial statements.
