Fiscal Year

The Company's fiscal year ends on the Sunday closest to December 31. Each fiscal year consists of four 13-week quarters, with one extra week added in the fourth quarter every five to six years.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances are eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Some of the more significant estimates include the allowance for sales returns and assumptions used to determine stock-based compensation expense. Actual results could differ materially from those estimates.

Foreign Currency

The functional currency of most of the Company's subsidiaries is the applicable local currency. Assets and liabilities have been translated to U.S. dollars using the exchange rates effective on the balance sheet dates, while income and expense accounts are translated at the average rates in effect during the periods presented. The resulting translation adjustments are recorded as a component of other comprehensive income within stockholders' equity.

The Company also recognizes gains and losses associated with transactions that are denominated in foreign currencies. The Company recorded a net loss resulting from foreign currency transactions of approximately $374,000, $222,000 and $145,000 in the fiscal years ended January 1, 2012, January 2, 2011 and January 3, 2010, respectively, within other income, net in the consolidated statements of operations.

Concentration of Risk

The Company maintains the majority of its cash and cash equivalents in accounts with five major financial institutions within and outside the United States, in the form of demand deposits, money market accounts and time deposits. Deposits in these institutions may exceed the amounts of insurance provided, or deposits may not at all be covered by insurance. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company's trade accounts receivable are primarily derived from credit card purchases from customers and the majority are settled within two business days.

The Company's ability to acquire diamonds and fine jewelry is dependent on its relationships with various suppliers from whom it purchases diamonds and fine jewelry. The Company has reached agreements with certain suppliers to provide access to their inventories of diamonds for its customers, but the terms of these agreements are limited and do not govern the purchase of diamonds for its inventory. Purchase concentration by major supply vendor in fiscal year ended January 1, 2012 with comparative information for fiscal years ended January 2, 2011 and January 3, 2010, is as follows:

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less, from the date of purchase, to be cash equivalents.

Short-term Investments

The Company classifies highly liquid investments with maturities greater than three months but less than one year as short-term investments.

Inventories

The Company's diamond, fine jewelry and watch inventories are classified at the lower of cost or market, using the specific identification method for diamonds and weighted average cost method for fine jewelry and watches. Commencing in December 2011, the Company no longer holds watches in its inventory. The Company lists loose diamonds and watches on its websites that are typically not included in inventory until the Company receives a customer order for those diamonds or watches. Upon receipt of a customer order, the Company purchases a specific diamond or watch and records it in inventory until it is delivered to the customer, at which time the revenue from the sale is recognized and inventory is relieved.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Maintenance and repairs are expensed as incurred. Depreciation expense is calculated on a straight-line basis over the estimated useful lives of the related assets. The cost and related accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and the related gain or loss is reported in the statement of operations. Estimated useful lives by major asset category are as follows:

Capitalized Software

The Company capitalizes costs to develop its websites and internal-use software and amortizes such costs on a straight-line basis over the estimated useful life of the software once it is available for use. Costs related to the design and maintenance of internal-use software and website development are expensed as incurred.

Impairment of Long-Lived Assets

The Company reviews the carrying value of its long-lived assets, including property and equipment and definite-lived intangible assets, whenever events or changes in circumstances indicate that the carrying value may not be recoverable. To the extent the estimated future cash inflows attributable to the assets, less estimated future cash outflows, are less than the carrying amount, an impairment loss would be recognized.

Intangible Assets

Intangible assets are recorded at cost and consist primarily of the costs incurred to acquire licenses and other similar agreements with finite lives. The gross carrying amount of these licenses was $0.5 million as of January 1, 2012 and $0.5 million as of January 2, 2011. Accumulated amortization was $314,000 and $260,000 as of January 1, 2012 and January 2, 2011, respectively. Amortization expense was $54,000 in the fiscal year ended January 1, 2012 and $51,000 in the fiscal year ended January 2, 2011. Amortization expense is estimated to be $58,000 in fiscal 2012, $55,000 in fiscal 2013, $37,000 in fiscal 2014, $22,000 in fiscal 2015, and $19,000 in fiscal 2016.

Intangible assets that are not being amortized relate to the Company's domain names, with total carrying amounts of $33,000 at both January 1, 2012 and January 2, 2011. These assets are tested for impairment annually and more frequently if certain circumstances indicate that impairment may have occurred.

Fair Value of Financial Instruments

The carrying amounts for the Company's cash, cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to their short maturities.

Treasury Stock

Treasury stock is recorded at cost and consists primarily of the repurchase of the Company's common stock in the open market.

Income Taxes

Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the tax rates that will be in effect when the differences are expected to reverse. Future tax benefits, such as return reserves, are recognized to the extent that realization of such benefits is considered to be more likely than not.

The Company utilizes a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. The Company does not have any unrecognized tax benefits. If interest and penalties related to unrecognized tax benefits were incurred, such amounts would be included in the Company's provision for income taxes.

Revenue Recognition

Net sales consist of products sold via the Internet and shipping revenue, net of estimated returns and promotional discounts and excluding sales taxes. The Company recognizes revenue when all of the following have occurred: persuasive evidence of an agreement with the customer exists, delivery has occurred or services have been rendered, the selling price is fixed or determinable and collectability of the selling price is reasonably assured. The Company evaluates whether it is appropriate to record the gross amount of product sales and related costs or the net amount earned. Revenue is recorded at the gross amount when the Company is the primary obligor, is subject to inventory and credit risk, has latitude in establishing price and product specification, or has most of these indicators. When the Company is not primarily obligated and has no latitude in establishing the price, revenue will be recorded at the net amount earned.

The Company requires payment at the point of sale. Amounts received before the customer assumes the risk of loss are not recorded as revenue. For sales to customers in the U.S., Canada and the E.U., the Company recognizes revenue when delivery has occurred, which is typically one to three days after shipment. For international sales, other than to Canada and the E.U., revenue is recognized upon shipment. The Company generally offers a return policy of 30 days and provides an allowance for sales returns during the period in which the sales are made. At January 1, 2012 and January 2, 2011, the reserve for sales returns was $1.1 million and $1.0 million, respectively, and was recorded as an accrued liability. Sales and cost of sales reported in the consolidated statements of operations are reduced to reflect estimated returns. The estimates are based on the Company's historical product return rates and current economic conditions.

During 2011, the Company offered a lifetime diamond upgrade program on all certified diamonds purchased since January 1, 2011. The Company concluded that this is a guarantee, versus a right of return, and estimated the fair value of the guarantee to be inconsequential. 

The Company generally does not extend credit to customers, except through third party credit cards. The majority of sales are through credit cards, and trade accounts receivable are composed primarily of amounts due from financial institutions related to credit card sales. The Company does not maintain an allowance for doubtful accounts because payment is typically received within two business days after the sale is complete.

Shipping and Handling Costs

The Company's shipping and handling costs primarily include payments to third-parties for shipping merchandise to the Company's customers. Shipping and handling costs of $4.2 million, $3.2 million and $2.8 million in the fiscal years ended January 1, 2012, January 2, 2011 and January 3, 2010, respectively, were included in cost of sales.

Cost of Sales

Cost of sales consists of the cost of merchandise sold to customers, inbound and outbound shipping costs, insurance on shipments, the costs incurred to set diamonds into ring, earring and pendant settings, including labor and related facility costs, and depreciation on assembly related property, plant and equipment.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of payroll and related benefit costs for the Company's employees, marketing costs, stock-based compensation and credit card fees. These expenses also include certain facility-related costs, and fulfillment, customer service, technology and depreciation expenses, as well as professional fees and other general corporate expenses.

Fulfillment costs include costs incurred in operating and staffing the fulfillment center, including costs attributable to receiving, inspecting and warehousing inventories and picking, packaging and preparing customers' orders for shipment. Fulfillment costs in the years ended January 1, 2012, January 2, 2011 and January 3, 2010 were approximately $3.5 million, $3.3 million and $3.0 million, respectively.

The Company has procedures in place to detect and prevent credit card fraud because the Company has exposure to losses from fraudulent charges. The Company records a reserve for fraud losses based on the Company's historical rate of such losses. This reserve is recorded as an accrued liability and amounted to $0.1 million at January 1, 2012, and $0.1 million at January 2, 2011.

Marketing

Marketing costs are expensed as incurred. Costs associated with web portal advertising contracts are amortized over the period such advertising is expected to be used. Costs of advertising associated with radio, print and other media are expensed when such services are used. Marketing expense for the years ended January 1, 2012, January 2, 2011 and January 3, 2010 was approximately $16.9 million, $14.5 million and $11.6 million, respectively.

Stock-Based Compensation

The Company measures compensation cost for all stock options and restricted stock units granted based on fair value on the measurement date, which is typically the grant date. The fair value of each stock option granted is estimated on the grant date using the Black-Scholes-Merton option valuation model. The fair value of each restricted stock unit is based on the fair market value of the Company's common stock on the date of the grant. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period for each stock option or restricted stock unit grant expected to vest with forfeitures estimated at the date of grant based on the Company's historical experience and future expectations. See Note 6 for additional details.

Stock Option Plans

The Company's 1999 Equity Incentive Plan ("1999 Plan") provides for the grant of incentive stock options, non-statutory stock options, stock bonuses and restricted stock awards, which may be granted to employees, including officers, non-employee directors and consultants. Options granted under the 1999 Plan generally provide for 25% vesting on the first anniversary from the date of grant with the remainder vesting monthly over the subsequent three years and expire 10 years from the date of grant. Options granted under the 1999 Plan were generally granted at fair value on the date of the grant. As of May 19, 2004, the effective date of the Company's initial public offering, no additional awards were granted under the 1999 Plan.

The Company's 2004 Equity Incentive Plan ("2004 Plan") provides for the grant of non-statutory stock options, restricted stock awards, stock appreciation rights, restricted stock units and other forms of equity compensation, which may be granted to employees, including officers, non-employee directors and consultants. As of January 1, 2012, the Company reserved 5,311,234 shares of common stock for future grants under the 2004 Plan, which amount will be increased annually on the first day of each fiscal year, up to and including 2014, by five percent of the number of shares of common stock outstanding on such date unless a lower number of shares is approved by the board of directors.

Options granted under the 2004 Plan generally provide for 25% vesting on the first anniversary of the date of grant with the remainder vesting monthly over the subsequent three years, and generally expire 10 years from the date of grant.

The Company's 2004 Non-Employee Directors' Stock Option Plan ("Directors' Plan") provides for the automatic grant of non-statutory stock options to purchase shares of common stock to non-employee directors. As of January 1, 2012, the Company reserved 389,818 shares of common stock for future grants under the Directors' Plan, which amount will be increased annually on the first day of each fiscal year, up to and including 2014, by the number of shares of common stock subject to options granted during the prior calendar year unless a lower number of shares is approved by the board of directors. There were 44,250 options granted under the Directors' Plan in the year ended January 1, 2012.

Employee Stock Purchase Plans

In April 2004, the Company adopted the 2004 Employee Stock Purchase Plan (the "Purchase Plan"). As of January 1, 2012, 1,000,000 shares of common stock are authorized to be sold under the Purchase Plan. Commencing on the first day of the fiscal year in which the Company first makes an offering under the Purchase Plan, this amount will be increased annually for 20 years. The increase in amount is the lesser of 320,000 shares or one and one half percent of the number of shares of common stock outstanding on each such date, unless a lower number of shares is approved by the board of directors. The Purchase Plan is intended to qualify as an "employee stock purchase plan" within the meaning of Section 423 of the Internal Revenue Code. As of January 1, 2012, no shares of common stock have been offered for sale under the Purchase Plan.

Option Grants to Non-Employees

The Company accounts for equity instruments issued to non-employees at their fair value on the measurement date.

Stock-Based Compensation Expense

The following weighted average assumptions were used for the valuation of stock options granted during the periods presented:

The assumptions used to calculate the fair value of options granted are evaluated and revised, as necessary, to reflect market conditions and the Company's experience.

The following table represents total stock-based compensation expense recognized in the consolidated financial statements (in thousands):

Stock-based compensation capitalized is included in property and equipment, net, in the consolidated balance sheets as a component of the cost capitalized for website development and the development of software for internal use. As of January 1, 2012, the Company had total unrecognized compensation costs related to unvested stock options of $8.8 million, before income taxes. The Company expects to recognize this cost over a weighted average period of 2.86 years.

The aggregate intrinsic values in the table above are before applicable income taxes and represent the amounts recipients would have received if all options had been exercised on the last business day of the period indicated, based on the Company's closing stock price.

The following table summarizes additional information about stock options outstanding at January 1, 2012:

The total intrinsic value of options exercised was $5.9 million, $15.4 million and $6.2 million in the years ended January 1, 2012, January 2, 2011 and January 3, 2010, respectively. During the years ended January 1, 2012, January 2, 2011 and January 3, 2010, the total fair value of options vested was $6.4 million, $6.8 million and $7.4 million, respectively.

During 2011, there were no restricted stock units granted, approximately 5,000 restricted stock units vested, and the remaining restricted stock units were cancelled. As of January 1, 2012, the Company has no restricted stock units that are vested or are expected to vest.

In February 2010, the Company's board of directors authorized the repurchase of up to $100.0 million of its common stock within the 24-month period following the approval date of such additional repurchase. In the year ended January 1, 2012, the Company repurchased 1.1 million shares of the Company's common stock for an aggregate purchase price of approximately $39.9 million. In the year ended January 2, 2011, the Company repurchased 0.5 million shares of the Company's common stock for an aggregate purchase price of approximately $25.3 million. In the year ended January 3, 2010, the Company did not repurchase shares of the Company's common stock.
