These principles require management to make certain estimates and assumptions during the preparation of its consolidated financial statements. These estimates and assumptions impact the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amount of net earnings during any period. Actual results could differ from those estimates. In the opinion of HSNi's management, the assumptions underlying these interim unaudited financial statements are reasonable.</font></div><div style="line-height:120%;padding-top:12px;text-indent:32px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Significant estimates underlying the accompanying consolidated financial statements include: the determination of the lower of cost or market adjustment for inventory; sales returns and other revenue allowances; the allowance for doubtful accounts; the recoverability of long-lived assets; the impairment of intangible assets; the determination of deferred income taxes, including related valuation allowances; the accrual for actual, pending or threatened litigation, claims and assessments; and assumptions related to the determination of incentive compensation and contingent consideration.</font></div></div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for all significant accounting policies of the reporting entity.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18780-107790 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18726-107790 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Accounting Principles Board Opinion (APB) -Number 22 -Paragraph 8 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
