as a lease obligation. Certain leases contain provisions that require additional rental payments based upon restaurant sales volume (contingent rentals). Contingent rentals are
accrued each period as the liabilities are incurred, in addition to the straight-line rent expense noted above. This results in some variability in occupancy expense as a percentage of revenues over the term of the lease in restaurants where we pay
Management makes judgments regarding the probable term for each restaurant property lease, which can impact the
classification and accounting for a lease as capital or operating, the rent holiday and/or escalations in payments that are taken into consideration when calculating straight-line rent and the term over which leasehold improvements for each
restaurant are amortized. These judgments may produce materially different amounts of depreciation, amortization and rent expense than would be reported if different assumed lease terms were used.
In an exposure draft issued in 2010, the FASB, together with the International Accounting Standards Board, has proposed a comprehensive set of changes in
accounting for leases. While the Exposure Draft addresses new financial accounting rules for both lessors and lessees, the primary focus will likely be on changes affecting lessees. The lease accounting model contemplated by the new standard is a
right of use model that assumes that each lease creates an asset (the lessees right to use the leased asset) and a liability (the future rental payment obligations) which should be reflected on a lessees balance sheet to
fairly represent the lease transaction and the lessees related financial obligations. Currently, all of our restaurant leases and our home office lease are accounted for as operating leases, with no related assets and liabilities on our
balance sheet. The FASB has reopened the Exposure Draft for comments and has therefore not identified a proposed effective date for the issuance of the final standard. Changes in these accounting rules or their interpretation, or changes in
underlying assumptions, estimates or judgments by us could significantly change our reported or expected financial performance.
of Financial Instruments
The carrying value of cash and cash equivalents, investments classified as held-to-maturity or current assets,
accounts receivable, and current liabilities approximate fair values due to the short-term maturity of these instruments. Investments classified as available-for-sale or non-current assets are recorded at fair value based on valuation models and
methodologies provided by a third party using Level 3 inputs when the fair value of the investment cannot be determined based on current trades on the open market. The fair value of long-term debt is determined using current applicable
rates for similar instruments as of the balance sheet date and approximates the carrying value of such obligations. Temporary changes in fair value results in unrealized holding gains and losses being recorded in the other comprehensive income
(loss) component of shareholders equity and does not affect net income for the applicable accounting period. Declines in fair value below our carrying value deemed to be other than temporary are charged against net earnings.
Net Income Per Share
Basic net income
per share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares outstanding during the period. At January 3, 2012, approximately 0.5 million shares of restricted stock
units issued to team members were unvested, and were therefore excluded from the calculation of basic earnings per share for the 53 weeks ended January 3, 2012. Diluted net income per share reflects the potential dilution that could occur
if stock options issued by us to sell common stock at set prices were exercised and if restrictions on restricted stock units issued by us were to lapse. The consolidated financial statements present basic and diluted net income per share. Common
share equivalents included in the diluted computation represent shares to be issued upon assumed exercises of outstanding stock options and the assumed lapsing of the restrictions on restricted stock units using the treasury stock method.
