Comparison of Fiscal Years Ended December 27, 2007 and December 30, 2006 Net Sales
## Table 1 ##
The increase in total net sales during fiscal 2007 was primarily due to the introduction of over 60 new products and overall demand for our automotive products.
The aviation, marine, and outdoor/fitness segments also experienced solid growth in 2007.
Total units sold increased 128% to 12.3 million in 2007 from 5.4 million in 2006.
The increase in net sales to consumers was primarily due to the introduction of many new automotive, outdoor/fitness, and marine products, strong demand for our automotive products, and solid demand for our aviation, marine, and outdoor/fitness products.
It is management’s belief that the continued demand for the Company’s automotive products is due to overall increased consumer awareness of the capabilities and applications of GPS, particularly as those capabilities pertain to automobile navigation.
Additionally, the expansion of the GPS market in general, as well as enhanced feature sets in our products specifically, has added to our growth.
Innovative new product offerings, enhanced cartography, rich feature sets, and products featuring high sensitivity GPS capabilities increased sales of our marine and outdoor fitness segments.
The increase in aviation sales for fiscal 2007 was primarily due to increased sales from panel mount products sold into the OEM (original equipment manufacturers) and retrofit markets.
Sales of the G1000 integrated glass cockpit were the primary reason for increased OEM sales in 2006.
While Temporary Flight Restrictions (TFR's) continue to impact general aviation, the flying community is adapting to these changes and returning to the skies in greater numbers.
Gross Profit
## Table 2 ##
The increase in gross profit dollars was primarily attributable to the introduction of over 60 new products and strong demand for our automotive and outdoor/fitness products.
The reduction in gross margin percentage was primarily due to the strong growth experienced in our lower-margin automotive/mobile product line, offset to some extent by strong gross margins in our other three segments.
Notably gross margin in our automotive/mobile segment did not fall as much as anticipated due to volume discounts on certain components, less price competition than anticipated, and new “premium” feature-rich products with higher selling prices and margins.
The rise in aviation gross margin was primarily due to a shift in product mix within our OEM and retrofit products.
The decline in gross margin in the outdoor/fitness and marine segments was primarily due to a shift in product mix.
December 27, 2008, December 29, 2007, and December 30, 2006, respectively.
In the next five years, the amortization expense is estimated to be $22,859, $22,285, $20,408, $10,465, and $3,965, respectively.
Marketable Securities Management determines the appropriate classification of marketable securities at the time of purchase and reevaluates such designation as of each balance sheet date.
All of the Company’s marketable securities are considered available-for-sale at December 27, 2008.
See Note 3.
Available-for-sale securities are stated at fair value, with the unrealized gains and losses, net of tax, reported in other comprehensive gain/(loss).
At December 27, 2008 and December 29, 2007, cumulative unrealized gains/(losses) of ($22,345) and $46,445, respectively, were reported accumulated in other comprehensive gain/(loss), net of related taxes.
The amortized cost of debt securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts to maturity, or in the case of mortgage-backed securities, over the estimated life of the security.
Such amortization is included in interest income from investments.
Realized gains and losses, and declines in value judged to be other-than-temporary are included in other income.
The cost of securities sold is based on the specific identification method.
Income Taxes The Company accounts for income taxes using the liability method in accordance with SFAS No.109, Accounting for Income Taxes.
The liability method provides that deferred tax assets and liabilities are recorded based on the difference between the tax bases of assets and liabilities and their carrying amount for financial reporting purposes as measured by the enacted tax rates and laws that will be in effect when the differences are expected to reverse.
Income taxes of $153,170 and $149,071 at December 27, 2008 and December 29, 2007, respectively, have not been accrued by the Company for the unremitted earnings of several of its subsidiaries because such earnings are intended to be reinvested in the subsidiaries indefinitely.
The Company adopted the provisions of FASB Interpretation No.48, Accounting for Uncertainty in Income Taxes (FIN 48), on December 31, 2006, the beginning of fiscal year 2007.
As a result of the implementation of FIN 48, the Company has not recognized a material increase or decrease in the liability for unrecognized tax benefits.
The total amount of unrecognized tax benefits as of December 27, 2008 was $214.4 million including interest of $11.1 million.
A reconciliation of the beginning and ending amount of unrecognized tax benefits for years ending December 27, 2008 and December 29, 2007 is as follows (in $millions):
