Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Maiden Holdings, Ltd. ("Maiden Holdings") and its subsidiaries (the "Company" or "Maiden"). They have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All significant intercompany transactions and accounts have been eliminated. These interim unaudited Condensed Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim period and all such adjustments are of a normal recurring nature. The results of operations for the interim period are not necessarily indicative, if annualized, of those to be expected for the full year. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. These unaudited Condensed Consolidated Financial Statements, including these notes, should be read in conjunction with the Company's audited Consolidated Financial Statements, and related notes thereto, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. Certain prior year comparatives have been reclassified to conform to the current year presentation. The effect of these reclassifications had no impact on previously reported shareholders' equity or net loss.
Recently Adopted Accounting Standards Updates and Recently Issued Accounting Standards Not Yet Adopted	Recently Adopted Accounting Standards Updates Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-13 ("ASU 2018-13") for changes to the disclosure framework related to Topic 820 which amends the disclosure requirements for fair value measurement. The following disclosure requirements were removed from Topic 820: (i) amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) policy for timing of transfers between levels, and (iii) valuation processes for Level 3 fair value measurements. The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added to Topic 820: (i) changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and (ii) range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in ASU 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of ASU 2018-13. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosures until their effective date. These amendments only impact disclosures made in "Note 5. Fair Value Measurements" therefore, the adoption of this standard on January 1, 2020 did not impact the Company’s consolidated balance sheets, results of operations or cash flows. Recently Issued Accounting Standards Not Yet Adopted Accounting for Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13 "Financial Instruments: Credit Losses (Topic 326)" replacing the "incurred loss" impairment methodology with an approach based on "expected losses" to estimate credit losses on certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance requires financial assets to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the cost of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. ASU 2016-13 also modified the accounting for available-for-sale ("AFS") debt securities, which must be individually assessed for credit losses when fair value is less than the amortized cost basis, in accordance with Subtopic 326-30, Financial Instruments: Credit Losses Available-for-Sale Debt Securities. Credit losses relating to AFS debt securities will be recorded through an allowance for credit losses rather than under the current other-than-temporarily impaired ("OTTI") methodology. In April 2019, the FASB issued ASU 2019-04 for targeted improvements related to ASU 2016-13 which clarify that an entity should include all expected recoveries in its estimate of the allowance for credit losses. In addition, for collateral dependent financial assets, the amendments mandate that an allowance for credit losses that is added to the amortized cost basis of the financial asset should not exceed amounts previously written off. It also clarifies FASB’s intent to include all reinsurance recoverables within the scope of Topic 944 to be within the scope of Subtopic 326-20, regardless of the measurement basis of those recoverables. The Company's reinsurance balances receivable and reinsurance recoverable on unpaid losses are its most significant financial assets within the scope of ASU 2016-13. The guidance is effective for public business entities, excluding entities eligible to be smaller reporting companies ("SRCs") as defined by the SEC, for annual periods beginning after December 15, 2019, and interim periods therein. The guidance is effective for all other entities, including public entities eligible to be SRCs, for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. As of December 31, 2019, the Company qualified for SRC status, as determined on the last business day of its most recent second quarter, and is thus eligible to follow the reporting deadlines and effective dates applicable to SRCs. Therefore Topic 326 will not be effective until the 2023 fiscal year. The Company continues to evaluate the impact of this guidance on its results of operations, financial condition and liquidity.
Fair Value of Financial Instruments	Fair Values of Financial Instruments Fair Value Measurements — Accounting Standards Codification ("ASC") Topic 820, "Fair Value Measurements and Disclosures" ("ASC 820") defines fair value as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between open market participants at the measurement date. Additionally, ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy is broken down into three levels based on the reliability of inputs as follows: •Level 1 — Valuations based on unadjusted quoted market prices for identical assets or liabilities that we have the ability to access. Because valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Examples of assets and liabilities utilizing Level 1 inputs include: U.S. Treasury bonds; •Level 2 — Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, or valuations based on models where the significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data. Examples of assets and liabilities utilizing Level 2 inputs include: U.S. government-sponsored agency securities; non-U.S. government and supranational obligations; commercial mortgage-backed securities ("CMBS"); collateralized loan obligations ("CLO"); corporate and municipal bonds; and •Level 3 — Valuations based on models where significant inputs are not observable. The unobservable inputs reflect our own assumptions about assumptions that market participants would use. Examples of assets and liabilities utilizing Level 3 inputs include: an investment in preference shares of a start-up insurance producer. The availability of observable inputs can vary and is affected by a wide variety of factors, including, for example, the type of financial instrument, whether the financial instrument is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires significantly more judgment. Accordingly, the degree of judgment exercised by management in determining fair value is greatest for instruments categorized in Level 3. 5. Fair Value of Financial Instruments (continued) We use prices and inputs that are current at the measurement date. In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified between levels. For investments that have quoted market prices in active markets, the Company uses the quoted market prices as fair value and includes these in the Level 1 hierarchy. The Company receives the quoted market prices from a third party nationally recognized provider ("the Pricing Service"). When quoted market prices are unavailable, the Company utilizes the Pricing Service to determine an estimate of fair value. The fair value estimates are included in the Level 2 hierarchy. The Company will challenge any prices for its investments which are considered not to be representative of fair value. If quoted market prices and an estimate from the Pricing Service are unavailable, the Company produces an estimate of fair value based on dealer quotations for recent activity in positions with the same or similar characteristics to that being valued. The Company determines whether the fair value estimate is in the Level 2 or Level 3 hierarchy depending on the level of observable inputs available when estimating the fair value. The Company bases its estimates of fair values for assets on the bid price as it represents what a third party market participant would be willing to pay in an orderly transaction. ASC 825, "Disclosure About Fair Value of Financial Instruments", requires all entities to disclose the fair value of their financial instruments, both assets and liabilities recognized and not recognized in the balance sheet, for which it is practicable to estimate fair value. The following describes the valuation techniques used by the Company to determine the fair value of financial instruments held at September 30, 2020 and December 31, 2019. U.S. government and U.S. agency — Bonds issued by the U.S. Treasury, the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation, Government National Mortgage Association, Federal National Mortgage Association and the Federal Farm Credit Banks Funding Corporation. The fair values of U.S. treasury bonds are based on quoted market prices in active markets, and are included in the Level 1 fair value hierarchy. We believe the market for U.S. treasury bonds is an actively traded market given the high level of daily trading volume. The fair values of U.S. agency bonds are determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. agency bonds are included in the Level 2 fair value hierarchy. Non-U.S. government and supranational bonds — These securities are generally priced by independent pricing services. The Pricing Service may use current market trades for securities with similar quality, maturity and coupon. If no such trades are available, the Pricing Service typically uses analytical models which may incorporate spreads, interest rate data and market/sector news. As the significant inputs used to price non-U.S. government and supranational bonds are observable market inputs, the fair values of non-U.S. government and supranational bonds are included in the Level 2 fair value hierarchy. Asset-backed securities — These securities comprise CMBS and CLO originated by a variety of financial institutions that on acquisition are rated BBB-/Baa3 or higher. These securities are priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. As the significant inputs used to price the CMBS and CLO are observable market inputs, the fair value of the CMBS and CLO securities are included in the Level 2 fair value hierarchy. Corporate and municipal bonds — Bonds issued by corporations, U.S. state and municipality entities or agencies that on acquisition are rated BBB-/Baa3 or higher. These securities are generally priced by independent pricing services. The credit spreads are sourced from broker/dealers, trade prices and the new issue market. Where pricing is unavailable from pricing services, custodian pricing or non-binding quotes are obtained from broker-dealers to estimate fair values. As the significant inputs used to price corporate and municipal bonds are observable market inputs, the fair values are included in the Level 2 fair value hierarchy. Other investments — Includes unquoted investments comprised of investments in limited partnerships, hedge funds and other investments which includes investments in special purpose vehicles focused on lending activities as well as investments in start-up insurance entities. The fair values of the limited partnerships and hedge funds are determined by the fund manager based on recent filings, operating results, balance sheet stability, growth and other business and market sector fundamentals. The fair value of these investments are measured using the NAV practical expedient and therefore have not been categorized within the fair value hierarchy. If there is a reporting lag between the current period end and reporting date of the latest available fund valuation, fair values are estimated by starting with the most recently available valuation and adjusting for return estimates as well as any subscriptions and distributions that took place during the current period. The investments made by SPVs focused on lending activities are carried at cost less impairment, if any, with any indication of impairment recognized in income when determined. As these investments are carried at cost, they are not included in the fair value hierarchy below. The fair value of the start-up insurance entities are determined using recent private market transactions and as such, the fair value of these investments are included in the Level 3 fair value hierarchy. Cash and cash equivalents (including restricted amounts), accrued investment income, reinsurance balances receivable, and certain other assets and liabilities — The carrying values reported in the Condensed Consolidated Balance Sheets for these financial instruments approximate their fair value due to their short term nature and are classified within the Level 2 fair value hierarchy. Loan to related party, reinsurance recoverable on unpaid losses, and funds withheld receivable — The carrying values reported in the Condensed Consolidated Balance Sheets for these financial instruments approximate their fair value and are included in the Level 2 fair value hierarchy. 5. Fair Value of Financial Instruments (continued) Senior notes — The carrying value for these financial instruments represents the principal value of the notes less any unamortized issuance costs. As these notes are presented at carrying value, they are not included in the fair value hierarchy below.

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Maiden Holdings, Ltd. ("Maiden Holdings") and its subsidiaries (the "Company" or "Maiden"). They have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All significant intercompany transactions and accounts have been eliminated.

These interim unaudited Condensed Consolidated Financial Statements reflect all adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim period and all such adjustments are of a normal recurring nature. The results of operations for the interim period are not necessarily indicative, if annualized, of those to be expected for the full year.

Recently Adopted Accounting Standards Updates

Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-13 ("ASU 2018-13") for changes to the disclosure framework related to Topic 820 which amends the disclosure requirements for fair value measurement. The following disclosure requirements were removed from Topic 820: (i) amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) policy for timing of transfers between levels, and (iii) valuation processes for Level 3 fair value measurements. The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added to Topic 820: (i) changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and (ii) range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements.

The amendments in ASU 2018-13 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of ASU 2018-13. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosures until their effective date. These amendments only impact disclosures made in "Note 5. Fair Value Measurements" therefore, the adoption of this standard on January 1, 2020 did not impact the Company’s consolidated balance sheets, results of operations or cash flows.

Accounting for Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13 "Financial Instruments: Credit Losses (Topic 326)" replacing the "incurred loss" impairment methodology with an approach based on "expected losses" to estimate credit losses on certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The guidance requires financial assets to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the cost of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. ASU 2016-13 also modified the accounting for available-for-sale ("AFS") debt securities, which must be individually assessed for credit losses when fair value is less than the amortized cost basis, in accordance with Subtopic 326-30, Financial Instruments: Credit Losses Available-for-Sale Debt Securities. Credit losses relating to AFS debt securities will be recorded through an allowance for credit losses rather than under the current other-than-temporarily impaired ("OTTI") methodology.

In April 2019, the FASB issued ASU 2019-04 for targeted improvements related to ASU 2016-13 which clarify that an entity should include all expected recoveries in its estimate of the allowance for credit losses. In addition, for collateral dependent financial assets, the amendments mandate that an allowance for credit losses that is added to the amortized cost basis of the financial asset should not exceed amounts previously written off. It also clarifies FASB’s intent to include all reinsurance recoverables within the scope of Topic 944 to be within the scope of Subtopic 326-20, regardless of the measurement basis of those recoverables. The Company's reinsurance balances receivable and reinsurance recoverable on unpaid losses are its most significant financial assets within the scope of ASU 2016-13.

The guidance is effective for public business entities, excluding entities eligible to be smaller reporting companies ("SRCs") as defined by the SEC, for annual periods beginning after December 15, 2019, and interim periods therein. The guidance is effective for all other entities, including public entities eligible to be SRCs, for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. As of December 31, 2019, the Company qualified for SRC status, as determined on the last business day of its most recent second quarter, and is thus eligible to follow the reporting deadlines and effective dates applicable to SRCs. Therefore Topic 326 will not be effective until the 2023 fiscal year. The Company continues to evaluate the impact of this guidance on its results of operations, financial condition and liquidity.

Fair Value of Financial Instruments

Fair Values of Financial Instruments

Fair Value Measurements — Accounting Standards Codification ("ASC") Topic 820, "Fair Value Measurements and Disclosures" ("ASC 820") defines fair value as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between open market participants at the measurement date. Additionally, ASC 820 establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

•Level 1 — Valuations based on unadjusted quoted market prices for identical assets or liabilities that we have the ability to access. Because valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Examples of assets and liabilities utilizing Level 1 inputs include: U.S. Treasury bonds;

•Level 2 — Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, or valuations based on models where the significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data. Examples of assets and liabilities utilizing Level 2 inputs include: U.S. government-sponsored agency securities; non-U.S. government and supranational obligations; commercial mortgage-backed securities ("CMBS"); collateralized loan obligations ("CLO"); corporate and municipal bonds; and

•Level 3 — Valuations based on models where significant inputs are not observable. The unobservable inputs reflect our own assumptions about assumptions that market participants would use. Examples of assets and liabilities utilizing Level 3 inputs include: an investment in preference shares of a start-up insurance producer.

The availability of observable inputs can vary and is affected by a wide variety of factors, including, for example, the type of financial instrument, whether the financial instrument is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires significantly more judgment. Accordingly, the degree of judgment exercised by management in determining fair value is greatest for instruments categorized in Level 3.

5. Fair Value of Financial Instruments (continued)

We use prices and inputs that are current at the measurement date. In periods of market dislocation, the observability of prices and inputs may be reduced for many instruments. This condition could cause an instrument to be reclassified between levels.

For investments that have quoted market prices in active markets, the Company uses the quoted market prices as fair value and includes these in the Level 1 hierarchy. The Company receives the quoted market prices from a third party nationally recognized provider ("the Pricing Service"). When quoted market prices are unavailable, the Company utilizes the Pricing Service to determine an estimate of fair value. The fair value estimates are included in the Level 2 hierarchy. The Company will challenge any prices for its investments which are considered not to be representative of fair value. If quoted market prices and an estimate from the Pricing Service are unavailable, the Company produces an estimate of fair value based on dealer quotations for recent activity in positions with the same or similar characteristics to that being valued. The Company determines whether the fair value estimate is in the Level 2 or Level 3 hierarchy depending on the level of observable inputs available when estimating the fair value. The Company bases its estimates of fair values for assets on the bid price as it represents what a third party market participant would be willing to pay in an orderly transaction.

ASC 825, "Disclosure About Fair Value of Financial Instruments", requires all entities to disclose the fair value of their financial instruments, both assets and liabilities recognized and not recognized in the balance sheet, for which it is practicable to estimate fair value. The following describes the valuation techniques used by the Company to determine the fair value of financial instruments held at September 30, 2020 and December 31, 2019.

U.S. government and U.S. agency — Bonds issued by the U.S. Treasury, the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation, Government National Mortgage Association, Federal National Mortgage Association and the Federal Farm Credit Banks Funding Corporation. The fair values of U.S. treasury bonds are based on quoted market prices in active markets, and are included in the Level 1 fair value hierarchy. We believe the market for U.S. treasury bonds is an actively traded market given the high level of daily trading volume. The fair values of U.S. agency bonds are determined using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. agency bonds are included in the Level 2 fair value hierarchy.

Non-U.S. government and supranational bonds — These securities are generally priced by independent pricing services. The Pricing Service may use current market trades for securities with similar quality, maturity and coupon. If no such trades are available, the Pricing Service typically uses analytical models which may incorporate spreads, interest rate data and market/sector news. As the significant inputs used to price non-U.S. government and supranational bonds are observable market inputs, the fair values of non-U.S. government and supranational bonds are included in the Level 2 fair value hierarchy.

Asset-backed securities — These securities comprise CMBS and CLO originated by a variety of financial institutions that on acquisition are rated BBB-/Baa3 or higher. These securities are priced by independent pricing services and brokers. The pricing provider applies dealer quotes and other available trade information, prepayment speeds, yield curves and credit spreads to the valuation. As the significant inputs used to price the CMBS and CLO are observable market inputs, the fair value of the CMBS and CLO securities are included in the Level 2 fair value hierarchy.

Corporate and municipal bonds — Bonds issued by corporations, U.S. state and municipality entities or agencies that on acquisition are rated BBB-/Baa3 or higher. These securities are generally priced by independent pricing services. The credit spreads are sourced from broker/dealers, trade prices and the new issue market. Where pricing is unavailable from pricing services, custodian pricing or non-binding quotes are obtained from broker-dealers to estimate fair values. As the significant inputs used to price corporate and municipal bonds are observable market inputs, the fair values are included in the Level 2 fair value hierarchy.

Other investments — Includes unquoted investments comprised of investments in limited partnerships, hedge funds and other investments which includes investments in special purpose vehicles focused on lending activities as well as investments in start-up insurance entities. The fair values of the limited partnerships and hedge funds are determined by the fund manager based on recent filings, operating results, balance sheet stability, growth and other business and market sector fundamentals. The fair value of these investments are measured using the NAV practical expedient and therefore have not been categorized within the fair value hierarchy. If there is a reporting lag between the current period end and reporting date of the latest available fund valuation, fair values are estimated by starting with the most recently available valuation and adjusting for return estimates as well as any subscriptions and distributions that took place during the current period.

The investments made by SPVs focused on lending activities are carried at cost less impairment, if any, with any indication of impairment recognized in income when determined. As these investments are carried at cost, they are not included in the fair value hierarchy below. The fair value of the start-up insurance entities are determined using recent private market transactions and as such, the fair value of these investments are included in the Level 3 fair value hierarchy.

Cash and cash equivalents (including restricted amounts), accrued investment income, reinsurance balances receivable, and certain other assets and liabilities — The carrying values reported in the Condensed Consolidated Balance Sheets for these financial instruments approximate their fair value due to their short term nature and are classified within the Level 2 fair value hierarchy.

Loan to related party, reinsurance recoverable on unpaid losses, and funds withheld receivable — The carrying values reported in the Condensed Consolidated Balance Sheets for these financial instruments approximate their fair value and are included in the Level 2 fair value hierarchy.

5. Fair Value of Financial Instruments (continued)

Senior notes — The carrying value for these financial instruments represents the principal value of the notes less any unamortized issuance costs. As these notes are presented at carrying value, they are not included in the fair value hierarchy below.
