assessments in all states , insurers licensed to transact certain classes of insurance are required to become members of a guaranty fund . in most states , in the event of the insolvency of an insurer writing any such class of insurance in the state , the guaranty funds may assess its members to pay covered claims of the insolvent insurers . assessments are based on each member 2019s proportionate share of written premiums in the state for the classes of insurance in which the insolvent insurer was engaged . assessments are generally limited for any year to one or two percent of the premiums written per year depending on the state . some states permit member insurers to recover assessments paid through surcharges on policyholders or through full or partial premium tax offsets , while other states permit recovery of assessments through the rate filing process . liabilities for guaranty fund and other insurance-related assessments are accrued when an assessment is probable , when it can be reasonably estimated , and when the event obligating the company to pay an imposed or probable assessment has occurred . liabilities for guaranty funds and other insurance- related assessments

and in certain instances enable the counterparties to terminate the agreements and demand immediate settlement of all outstanding derivative positions traded under each impacted bilateral agreement . the settlement amount is determined by netting the derivative positions transacted under each agreement . if the termination rights were to be exercised by the counterparties , it could impact the legal entity 2019s ability to conduct hedging activities by increasing the associated costs and decreasing the willingness of counterparties to transact with the legal entity . the aggregate fair value of all derivative instruments with credit-risk-related contingent features that are in a net liability position as of december 31 , 2016 was $ 1.4 billion . of this $ 1.4 billion , the legal

as collateral . based on derivative market values as of december 31 , 2016 , a downgrade of two levels below the current financial strength ratings by either moody 2019s or s&p would require additional $ 10 of assets to be posted as collateral . these collateral amounts could change as derivative market values change , as a result of changes in our hedging activities or to the extent changes in contractual terms are negotiated . the nature of the collateral that we post , when required , is primarily in the form of u.s . treasury bills , u.s . treasury notes and government agency securities . guarantees in the ordinary course of selling businesses or entities to third parties , the company has agreed to indemnify purchasers for losses arising subsequent to the closing due to
