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 period ended March 28, 2015 are not necessarily indicative of the results that may be expected for the year ending December 26, 2015.

The condensed consolidated balance sheet at December 27, 2014 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 27, 2014.

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 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 quarters having only 13 weeks. The quarters ended March 28, 2015 and March 29, 2014 both contain operating results for 13 weeks.

Commitments and Contingencies

6.	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. Pursuant to these agreements, the Company is contractually committed to make payments of approximately $372,852 over the next five years. Subsequent to March 28, 2015, a portion of a commitment was satisfied with a $43,000 prepayment to a supplier, the majority of which will be classified as a noncurrent asset.

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 March 28, 2015. 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 March 28, 2015 that did not individually or in the aggregate have a material impact on the Company’s financial condition or results of operations.

7. Income Taxes

The Company’s income tax expense decreased by $14,246, to $9,403 for the 13-week period ended March 28, 2015, from $23,649 for the 13-week period ended March 29, 2014. The effective tax rate was 12.3% in the first quarter of 2015 compared to 16.6% in the first quarter of 2014. Release of uncertain tax position reserves due to expiration of certain statutes of limitations or completion of tax audits reduced our expense by $5,287 and $5,795, respectively, in first quarter 2015 and first quarter 2014. The first quarter 2015 effective tax rate decreased as compared to first quarter 2014 primarily due to the current projected full year income mix for 2015 compared to the same projection at first quarter of 2014. The full year 2014 effective tax rate was subsequently reduced as our income projection increased and income mix by taxing jurisdiction improved throughout 2014.

8. Marketable Securities

The 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:

⁽²⁾ Represents impairment not related to credit for those investment securities that have been determined to be other-than-temporarily impaired.

⁽³⁾ 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 our 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 an 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. In 2013, Garmin experienced unrealized, noncredit losses on its investment portfolio resulting in gross other-than-temporary impairment and other unrealized losses on marketable securities. The decrease in estimated fair value was primarily due to market valuations declining on mortgage- and asset-backed securities and government and agency securities. During 2014 and the first quarter of 2015, 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 March 28, 2015 were $962,449 and $952,364, respectively. Approximately 43% of securities in our portfolio were at an unrealized loss position at March 28, 2015. 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 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 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 table displays 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 March 28, 2015.

Share Repurchase Plan

9. Share Repurchase Plan

On February 13, 2015, the Board of Directors approved a share repurchase program authorizing the Company to repurchase up to $300,000 of the common shares of Garmin Ltd. The repurchases may be made from time to time as market and business conditions warrant on the open market or in negotiated transactions in compliance with the SEC’s Rule 10b-18. The timing and amounts of any repurchases will be determined by the Company’s management depending on market conditions and other factors including price, regulatory requirements and capital availability. The program does not require the purchase of any minimum number of shares and may be suspended or discontinued at any time. The share repurchase authorization expires on December 31, 2016. As of March 28, 2015, the Company had repurchased 331 shares using cash of $16,260. There remains approximately $283,740 available to repurchase additional shares under this authorization.

11. Recently Issued Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update No. 2014-09 “Revenue from Contracts with Customers” (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 or transferring goods or services to a customer. In applying the new guidance, a company will (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the contract’s performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The provisions of this new guidance are effective for reporting periods beginning after December 15, 2016 and can be adopted using either a full retrospective or modified approach. The Company is currently evaluating the impact of adopting this new guidance on the Company’s financial statements.

In February 2015, Restricted Stock Units (RSUs) were granted to certain employees under the Company’s 2005 Equity Incentive Plan (the “2005 Plan”). The vesting of these RSUs is contingent upon the achievement of certain revenue and profitability goals, as well as on time-based vesting requirements. The compensation expense related to these grants did not have a material impact on the results of operations for the fiscal quarter ended March 28, 2015 and is not expected to have a material impact on the results of operations for the fiscal year ending December 26, 2015. The 2005 Plan is discussed further in our Annual Report on Form 10-K for the fiscal year ended December 27, 2014.
