Rent expense is included in occupancy and other operating expenses on the consolidated statements of income. The difference between rent expense and rent paid is recorded as deferred rent, which is included in other noncurrent liabilities in the accompanying consolidated balance sheets.

Actual results could materially differ from those estimates. The Company’s significant estimates include estimates for impairment of goodwill, intangible assets and property and equipment, insurance reserves, lease termination liabilities, closed-store reserves, stock-based compensation, income tax receivable agreement liability, and income tax valuation allowances.</font></div></div>
