It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits should not be reported as cash and cash equivalents.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7, 26 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 8, 9 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7 -Footnote 1 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 1 -Article 5 falsefalseCash and cash equivalents (includes $592 and $2,796 relating to Reciprocal Exchanges)7false0us-gaap_AccruedInvestmentIncomeReceivableus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truefalsefalse2648600026486falsefalsefalsefalsefalse2truefalsefalse2356200023562falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryInterest, dividends, rents, ancillary and other revenues earned but not yet received by the entity on its investments.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 3 -Article 5 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 4 -Article 7 falsefalseInvestment income receivable (includes $2,538 and $3,021 relating to Reciprocal Exchanges)8false0us-gaap_PremiumsReceivableAtCarryingValueus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truefalsefalse363996000363996falsefalsefalsefalsefalse2truefalsefalse387584000387584falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryThe carrying amount as of the balance sheet date due the entity from (a) agents and insureds, (b) uncollected premiums and (c) others, net of the allowance for doubtful accounts.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 5 -Article 7 falsefalsePremiums receivable (includes $36,673 and $53,953 relating to Reciprocal Exchanges)9false0us-gaap_ReinsuranceReceivablesPaidLossesRecoverableus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truefalsefalse2039400020394falsefalsefalsefalsefalse2truefalsefalse1821400018214falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryReceivables currently due from reinsurers for ceded claims paid.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 6 -Article 7 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 113 -Paragraph 14, 15 falsefalseReinsurance recoverable on paid losses (includes $2,487 and $2,167 relating to Reciprocal Exchanges)10false0us-gaap_ReinsuranceReceivablesIncurredButNotReportedClaimsus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truefalsefalse290352000290352falsefalsefalsefalsefalse2truefalsefalse282682000282682falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryThe portion of reinsurance receivables representing the aggregate amount of estimated amounts due as of the balance sheet date from another insurer;

Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits should not be reported as cash and cash equivalents.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7, 26 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 8, 9 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7 -Footnote 1 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 1 -Article 5 falsefalseCash and cash equivalents (includes $592 and $2,796 relating to Reciprocal Exchanges)34false0us-gaap_AccruedInvestmentIncomeReceivableus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truefalsefalse25380002538falsefalsefalsefalsefalse2truefalsefalse30210003021falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryInterest, dividends, rents, ancillary and other revenues earned but not yet received by the entity on its investments.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 3 -Article 5 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 4 -Article 7 falsefalseInvestment income receivable (includes $2,538 and $3,021 relating to Reciprocal Exchanges)35false0us-gaap_PremiumsReceivableAtCarryingValueus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truefalsefalse3667300036673falsefalsefalsefalsefalse2truefalsefalse5395300053953falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryThe carrying amount as of the balance sheet date due the entity from (a) agents and insureds, (b) uncollected premiums and (c) others, net of the allowance for doubtful accounts.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 5 -Article 7 falsefalsePremiums receivable (includes $36,673 and $53,953 relating to Reciprocal Exchanges)36false0us-gaap_ReinsuranceReceivablesPaidLossesRecoverableus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truefalsefalse24870002487falsefalsefalsefalsefalse2truefalsefalse21670002167falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryReceivables currently due from reinsurers for ceded claims paid.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 6 -Article 7 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 113 -Paragraph 14, 15 falsefalseReinsurance recoverable on paid losses (includes $2,487 and $2,167 relating to Reciprocal Exchanges)37false0us-gaap_ReinsuranceReceivablesIncurredButNotReportedClaimsus-gaaptruedebitinstantNo definition available.falsefalsefalsefalsefalsefalsefalsefalsefalsefalseverboselabel1truefalsefalse1175700011757falsefalsefalsefalsefalse2truefalsefalse1509200015092falsefalsefalsefalsefalseMonetaryxbrli:monetaryItemTypemonetaryThe portion of reinsurance receivables representing the aggregate amount of estimated amounts due as of the balance sheet date from another insurer;
