Insurance Regulatory Restrictions	9. INSURANCE REGULATORY RESTRICTIONS United States: Ambac Assurance (exclusive of the Segregated Account which is under the control of OCI via the Segregated Account Rehabilitation Plan and Segregated Account Rehabilitation Proceedings) and Everspan are subject to the insurance laws and regulations of each jurisdiction in which it is licensed, some of which are described below. Failure to comply with applicable insurance laws and regulations (including, without limitation, minimum surplus requirements, aggregate risk limits and single risk limits) could expose Ambac Assurance or Everspan to fines, the loss or suspension of insurance licenses in certain jurisdictions, the imposition of orders by regulators with respect to the conduct of business by Ambac Assurance or Everspan and/or the inability to pay dividends, all of which could have an adverse impact on our business results and prospects. New York’s comprehensive financial guarantee insurance law defines the scope of permitted financial guarantee insurance and governs the conduct of business of all financial guarantors licensed to do business in New York, including Ambac Assurance. The New York financial guarantee insurance law also establishes single risk and aggregate limits with respect to obligations insured by financial guarantee insurers. Such single risk limits are specific to the type of insured obligation (for example, municipal or asset-backed). Under the aggregate limits, policyholders’ surplus and contingency reserves must at least equal a percentage of aggregate net financial guarantee liability that is equal to the sum of various percentages of aggregate net liability for various categories of specified obligations. Wisconsin laws and regulations applicable to financial guarantors, as well as the laws of several other states, are less comprehensive than New York law and relate primarily to single and aggregate risk limits. As a result of decreased statutory capital resulting from the significant losses experienced by Ambac Assurance, Ambac Assurance is not in compliance with applicable regulatory single and aggregate risk limits. Through run-off of the portfolio, Ambac Assurance will seek to reduce its exposure to no more than the permitted amounts, but may not be able to do so. Everspan is in compliance with all of such limits. Ambac Assurance’s ability to pay dividends is generally restricted by law and subject to approval by OCI. Wisconsin insurance law restricts the payment of dividends in any 12-month period without regulatory approval to the lesser of (a) 10% of policyholders’ surplus as of the preceding December 31, and (b) the greater of (i) statutory net income (loss) for the calendar year preceding the date of dividend, minus realized capital gains for that calendar year or (ii) the aggregate of statutory net income (loss) for three calendar years preceding the date of the dividend, minus realized capital gains for those calendar years and minus dividends paid or credited within the first two of the three preceding calendar years. In connection with the termination of reinsurance contracts, OCI requires adjustments to the dividend calculation for any surplus or net income gains recognized. Additionally, no quarterly dividend may exceed the dividend paid in the corresponding quarter of the preceding year by more than 15% without notifying OCI 30 days in advance of payment. Based upon these restrictions, at December 31, 2013, Ambac Assurance will not be able to pay common stock dividends during 2014 without regulatory approval. Ambac Assurance did not pay cash dividends on its common stock in 2013 or 2012. Ambac Assurance’s statutory financial statements are prepared on the basis of accounting practices prescribed or permitted by OCI. OCI recognizes only statutory accounting practices prescribed or permitted by the State of Wisconsin for determining and reporting the financial condition and results of operations of an insurance company for determining its solvency under Wisconsin Insurance Law. The National Association of Insurance Commissioners (“NAIC”) Accounting Practices and Procedures manual (“NAIC SAP”) has been adopted as a component of prescribed practices by the State of Wisconsin. Ambac Assurance’s statutory policyholder surplus and qualified statutory capital were $840,262 and $905,065 at December 31, 2013, respectively as compared to $100,000 and $628,302 as of December 31, 2012, respectively. The Segregated Account reported statutory policyholder surplus of $442,639 and ($61,812) as of December 31, 2013 and 2012, respectively. At December 31, 2013, Ambac Assurance’s surplus as regards to policyholders exceeds the Minimum Surplus Amount. At December 31, 2012, Ambac Assurance’s surplus as regards to policyholders was at the Minimum Surplus and therefore $163,687 of the Segregated Account’s insurance liabilities were not assumed by Ambac Assurance under the Reinsurance Agreement. Statutory capital and surplus differs from stockholders’ equity determined under GAAP principally due to statutory accounting rules that treat loss reserves, consolidation of subsidiaries, premiums earned, policy acquisition costs and deferred income taxes differently. Additionally, Fresh Start accounting is not applicable under statutory accounting principles. The Wisconsin Insurance Commissioner has prescribed or permitted additional accounting practices for Ambac Assurance and the Segregated Account of Ambac Assurance. As a result of the prescribed and permitted practices discussed below, Ambac Assurance’s statutory surplus at December 31, 2013 and December 31, 2012 was lower by $227,334 and greater by $81,846, respectively, than if Ambac Assurance and the Segregated Account had reported such amounts in accordance with NAIC SAP. OCI has prescribed an accounting practice related to the total liabilities and total surplus of the Segregated Account that are reported as discrete components of Ambac Assurance’s liabilities and surplus reported in Ambac Assurance’s statutory basis financial statements. Pursuant to this prescribed practice, the results of the Segregated Account are not included in Ambac Assurance’s financial statements if Ambac Assurance’s surplus is (or would be) less than the Minimum Surplus Amount. OCI has prescribed an additional accounting practice that differs from NAIC SAP. Paragraph 7 of Statement of Statutory Accounting Principles No. 60 “Financial Guaranty Insurance” (“SSAP 60”) allows for a deduction from loss reserves for the time value of money by application of a discount rate equal to the average rate of return on the admitted assets of the financial guaranty insurer as of the date of the computation of the reserve. The discount rate shall be adjusted at the end of each calendar year. Additionally, in accordance with paragraph 7 of Statutory Accounting Principles No. 5 “Liabilities, Contingencies and Impairments of Assets,” Ambac Assurance records probable losses on its subsidiaries credit derivative contracts, using a discount rate equal to the average rate of return on its admitted assets. Ambac Assurance’s average rates of return on its admitted assets at December 31, 2013 and December 31, 2012 were 9.80% and 8.01%, respectively. OCI has directed Ambac Assurance to utilize a prescribed discount rate of 5.10% for the purpose of discounting both its loss reserves and its estimated impairment losses on subsidiary guarantees. OCI has prescribed an additional accounting practice that differs from NAIC SAP. Paragraph 4 of Statement of Statutory Accounting Principles No. 41 “Surplus Notes” (“SSAP 41”) states that proceeds received by the issuer of surplus notes must be in the form of cash or other admitted assets having readily determinable values and liquidity satisfactory to the commissioner of the state of domicile. Under the statutory accounting principles as generally applied, surplus notes issued in conjunction with commutations or the settlement of claims would be valued at zero upon issuance pursuant to paragraph 4, SSAP 41. OCI has directed Ambac Assurance to record surplus notes issued in connection with commutations or the settlement of claims at full par value upon issuance as in these instances the surplus notes do not represent a contribution of capital, but rather a distribution of value from the common and preferred shareholders of Ambac Assurance. The surplus notes issued in connection with commutations or settlement of claims has a claim against surplus senior to the preferred and common shareholders. Statutory surplus is not impacted as a result of the prescribed practice as it is a reclassification from unassigned funds to surplus notes. OCI has extended the preceding prescribed practice related to surplus notes to the evaluation of other-than-temporary impairments for Ambac Assurance guaranteed securities held in the investment portfolio. Paragraph 35 of Statement of Statutory Accounting Principles No. 43R “Loan-backed and Structured Securities” states that when an other-than-temporary impairment has occurred, the amount of the other-than-temporary impairment recognized as a realized loss shall equal the difference between the investment’s amortized cost basis and the present value of cash flows expected to be collected, discounted at the loan-backed or structured security’s effective interest rate. Under NAIC SAP, the present value of cash flows expected to be collected should include the fair value of surplus notes received from Ambac Assurance, as required under the confirmed Segregated Account Rehabilitation Plan. OCI has prescribed an accounting practice that differs from NAIC SAP and has directed Ambac Assurance to utilize par value rather than fair value of these surplus notes in this computation. Wisconsin accounting practices for changes to contingency reserves differ from NAIC SAP. Under NAIC SAP, contributions to and releases from the contingency reserve are recorded via a direct charge or credit to surplus. Under the Wisconsin Administrative Code, contributions to and releases from the contingency reserve are to be recorded through underwriting income. Ambac Assurance received permission from OCI to record contributions to and releases from the contingency reserve and the related tax and loss bond impact, in accordance with NAIC SAP. Statutory surplus is the same using each of these accounting practices. Ambac Assurance received permission from OCI to report investment holdings of Ambac Assurance insured securities, with coverage under financial guaranty policies that have been allocated to the Segregated Account, as a separate invested asset on the balance sheet rather than combined with other bond investments. This permitted practice only impacts the balance sheet classification and has no impact on the valuation of the securities to which it applies or to statutory surplus. United Kingdom The Prudential Regulatory Authority (“PRA”) and Financial Conduct Authority (“FCA”) (and their predecessor regulator the Financial Services Authority (“FSA”)) have exercised significant oversight of Ambac UK since 2008, after Ambac, Ambac Assurance and Ambac UK began experiencing financial stress. In 2009, Ambac UK’s license to write new business was curtailed by the FSA and the insurance license was limited to undertaking only run-off related activity. As such, Ambac UK is authorized to run-off its credit, suretyship and financial guarantee insurance portfolio in the United Kingdom, and to do the same through a branch in Milan, Italy, and a number of other European Union (“EU”) countries. EU legislation has allowed Ambac UK to conduct business in EU states other than the United Kingdom through a “passporting” arrangement, which eliminates the necessity of additional licensing or authorization in those other EU jurisdictions. The PRA and FCA is the dual statutory regulator responsible for regulating the financial services industry in the United Kingdom, with the purpose of maintaining confidence in the U.K. financial system, providing public understanding of the system, securing the proper degree of protection for consumers and helping to reduce financial crime. In addition, the regulatory regime in the United Kingdom must comply with certain EU legislation binding on all EU member states. The PRA requires that non-life insurance companies such as Ambac UK maintain a margin of solvency at all times in respect of the liabilities of the insurance company, the calculation of which depends on the type and amount of insurance business a company writes.

9. INSURANCE REGULATORY RESTRICTIONS

United States:

Ambac Assurance (exclusive of the Segregated Account which is under the control of OCI via the Segregated Account Rehabilitation Plan and Segregated Account Rehabilitation Proceedings) and Everspan are subject to the insurance laws and regulations of each jurisdiction in which it is licensed, some of which are described below. Failure to comply with applicable insurance laws and regulations (including, without limitation, minimum surplus requirements, aggregate risk limits and single risk limits) could expose Ambac Assurance or Everspan to fines, the loss or suspension of insurance licenses in certain jurisdictions, the imposition of orders by regulators with respect to the conduct of business by Ambac Assurance or Everspan and/or the inability to pay dividends, all of which could have an adverse impact on our business results and prospects.

New York’s comprehensive financial guarantee insurance law defines the scope of permitted financial guarantee insurance and governs the conduct of business of all financial guarantors licensed to do business in New York, including Ambac Assurance. The New York financial guarantee insurance law also establishes single risk and aggregate limits with respect to obligations insured by financial guarantee insurers. Such single risk limits are specific to the type of insured obligation (for example, municipal or asset-backed). Under the aggregate limits, policyholders’ surplus and contingency reserves must at least equal a percentage of aggregate net financial guarantee liability that is equal to the sum of various percentages of aggregate net liability for various categories of specified obligations. Wisconsin laws and regulations applicable to financial guarantors, as well as the laws of several other states, are less comprehensive than New York law and relate primarily to single and aggregate risk limits.

As a result of decreased statutory capital resulting from the significant losses experienced by Ambac Assurance, Ambac Assurance is not in compliance with applicable regulatory single and aggregate risk limits. Through run-off of the portfolio, Ambac Assurance will seek to reduce its exposure to no more than the permitted amounts, but may not be able to do so. Everspan is in compliance with all of such limits.

Ambac Assurance’s ability to pay dividends is generally restricted by law and subject to approval by OCI. Wisconsin insurance law restricts the payment of dividends in any 12-month period without regulatory approval to the lesser of (a) 10% of policyholders’ surplus as of the preceding December 31, and (b) the greater of (i) statutory net income (loss) for the calendar year preceding the date of dividend, minus realized capital gains for that calendar year or (ii) the aggregate of statutory net income (loss) for three calendar years preceding the date of the dividend, minus realized capital gains for those calendar years and minus dividends paid or credited within the first two of the three preceding calendar years. In connection with the termination of reinsurance contracts, OCI requires adjustments to the dividend calculation for any surplus or net income gains recognized. Additionally, no quarterly dividend may exceed the dividend paid in the corresponding quarter of the preceding year by more than 15% without notifying OCI 30 days in advance of payment. Based upon these restrictions, at December 31, 2013, Ambac Assurance will not be able to pay common stock dividends during 2014 without regulatory approval. Ambac Assurance did not pay cash dividends on its common stock in 2013 or 2012.

Ambac Assurance’s statutory financial statements are prepared on the basis of accounting practices prescribed or permitted by OCI. OCI recognizes only statutory accounting practices prescribed or permitted by the State of Wisconsin for determining and reporting the financial condition and results of operations of an insurance company for determining its solvency under Wisconsin Insurance Law. The National Association of Insurance Commissioners (“NAIC”) Accounting Practices and Procedures manual (“NAIC SAP”) has been adopted as a component of prescribed practices by the State of Wisconsin.

Ambac Assurance’s statutory policyholder surplus and qualified statutory capital were $840,262 and $905,065 at December 31, 2013, respectively as compared to $100,000 and $628,302 as of December 31, 2012, respectively. The Segregated Account reported statutory policyholder surplus of $442,639 and ($61,812) as of December 31, 2013 and 2012, respectively. At December 31, 2013, Ambac Assurance’s surplus as regards to policyholders exceeds the Minimum Surplus Amount. At December 31, 2012, Ambac Assurance’s surplus as regards to policyholders was at the Minimum Surplus and therefore $163,687 of the Segregated Account’s insurance liabilities were not assumed by Ambac Assurance under the Reinsurance Agreement. Statutory capital and surplus differs from stockholders’ equity determined under GAAP principally due to statutory accounting rules that treat loss reserves, consolidation of subsidiaries, premiums earned, policy acquisition costs and deferred income taxes differently. Additionally, Fresh Start accounting is not applicable under statutory accounting principles.

The Wisconsin Insurance Commissioner has prescribed or permitted additional accounting practices for Ambac Assurance and the Segregated Account of Ambac Assurance. As a result of the prescribed and permitted practices discussed below, Ambac Assurance’s statutory surplus at December 31, 2013 and December 31, 2012 was lower by $227,334 and greater by $81,846, respectively, than if Ambac Assurance and the Segregated Account had reported such amounts in accordance with NAIC SAP.

OCI has prescribed an accounting practice related to the total liabilities and total surplus of the Segregated Account that are reported as discrete components of Ambac Assurance’s liabilities and surplus reported in Ambac Assurance’s statutory basis financial statements. Pursuant to this prescribed practice, the results of the Segregated Account are not included in Ambac Assurance’s financial statements if Ambac Assurance’s surplus is (or would be) less than the Minimum Surplus Amount.

OCI has prescribed an additional accounting practice that differs from NAIC SAP. Paragraph 7 of Statement of Statutory Accounting Principles No. 60 “Financial Guaranty Insurance” (“SSAP 60”) allows for a deduction from loss reserves for the time value of money by application of a discount rate equal to the average rate of return on the admitted assets of the financial guaranty insurer as of the date of the computation of the reserve. The discount rate shall be adjusted at the end of each calendar year. Additionally, in accordance with paragraph 7 of Statutory Accounting Principles No. 5 “Liabilities, Contingencies and Impairments of Assets,” Ambac Assurance records probable losses on its subsidiaries credit derivative contracts, using a discount rate equal to the average rate of return on its admitted assets. Ambac Assurance’s average rates of return on its admitted assets at December 31, 2013 and December 31, 2012 were 9.80% and 8.01%, respectively. OCI has directed Ambac Assurance to utilize a prescribed discount rate of 5.10% for the purpose of discounting both its loss reserves and its estimated impairment losses on subsidiary guarantees.

OCI has prescribed an additional accounting practice that differs from NAIC SAP. Paragraph 4 of Statement of Statutory Accounting Principles No. 41 “Surplus Notes” (“SSAP 41”) states that proceeds received by the issuer of surplus notes must be in the form of cash or other admitted assets having readily determinable values and liquidity satisfactory to the commissioner of the state of domicile. Under the statutory accounting principles as generally applied, surplus notes issued in conjunction with commutations or the settlement of claims would be valued at zero upon issuance pursuant to paragraph 4, SSAP 41. OCI has directed Ambac Assurance to record surplus notes issued in connection with commutations or the settlement of claims at full par value upon issuance as in these instances the surplus notes do not represent a contribution of capital, but rather a distribution of value from the common and preferred shareholders of Ambac Assurance. The surplus notes issued in connection with commutations or settlement of claims has a claim against surplus senior to the preferred and common shareholders. Statutory surplus is not impacted as a result of the prescribed practice as it is a reclassification from unassigned funds to surplus notes.

OCI has extended the preceding prescribed practice related to surplus notes to the evaluation of other-than-temporary impairments for Ambac Assurance guaranteed securities held in the investment portfolio. Paragraph 35 of Statement of Statutory Accounting Principles No. 43R “Loan-backed and Structured Securities” states that when an other-than-temporary impairment has occurred, the amount of the other-than-temporary impairment recognized as a realized loss shall equal the difference between the investment’s amortized cost basis and the present value of cash flows expected to be collected, discounted at the loan-backed or structured security’s effective interest rate. Under NAIC SAP, the present value of cash flows expected to be collected should include the fair value of surplus notes received from Ambac Assurance, as required under the confirmed Segregated Account Rehabilitation Plan. OCI has prescribed an accounting practice that differs from NAIC SAP and has directed Ambac Assurance to utilize par value rather than fair value of these surplus notes in this computation.

Wisconsin accounting practices for changes to contingency reserves differ from NAIC SAP. Under NAIC SAP, contributions to and releases from the contingency reserve are recorded via a direct charge or credit to surplus. Under the Wisconsin Administrative Code, contributions to and releases from the contingency reserve are to be recorded through underwriting income. Ambac Assurance received permission from OCI to record contributions to and releases from the contingency reserve and the related tax and loss bond impact, in accordance with NAIC SAP. Statutory surplus is the same using each of these accounting practices.

Ambac Assurance received permission from OCI to report investment holdings of Ambac Assurance insured securities, with coverage under financial guaranty policies that have been allocated to the Segregated Account, as a separate invested asset on the balance sheet rather than combined with other bond investments. This permitted practice only impacts the balance sheet classification and has no impact on the valuation of the securities to which it applies or to statutory surplus.

United Kingdom

The Prudential Regulatory Authority (“PRA”) and Financial Conduct Authority (“FCA”) (and their predecessor regulator the Financial Services Authority (“FSA”)) have exercised significant oversight of Ambac UK since 2008, after Ambac, Ambac Assurance and Ambac UK began experiencing financial stress. In 2009, Ambac UK’s license to write new business was curtailed by the FSA and the insurance license was limited to undertaking only run-off related activity. As such, Ambac UK is authorized to run-off its credit, suretyship and financial guarantee insurance portfolio in the United Kingdom, and to do the same through a branch in Milan, Italy, and a number of other European Union (“EU”) countries. EU legislation has allowed Ambac UK to conduct business in EU states other than the United Kingdom through a “passporting” arrangement, which eliminates the necessity of additional licensing or authorization in those other EU jurisdictions.

The PRA and FCA is the dual statutory regulator responsible for regulating the financial services industry in the United Kingdom, with the purpose of maintaining confidence in the U.K. financial system, providing public understanding of the system, securing the proper degree of protection for consumers and helping to reduce financial crime. In addition, the regulatory regime in the United Kingdom must comply with certain EU legislation binding on all EU member states.

The PRA requires that non-life insurance companies such as Ambac UK maintain a margin of solvency at all times in respect of the liabilities of the insurance company, the calculation of which depends on the type and amount of insurance business a company writes.
