 with an underlying single or multiple high-quality fixed income investments, fixed income mutual funds, or with units of a collective trust bond portfolio. The wrap contract is owned by the Plan while the underlying investments may or may not be owned by the Plan, depending on the contract. Wrap contracts are issued by insurance or financial services institutions. Investment gains and losses are amortized over the expected duration of the underlying investments of that contract through the calculation of an interest rate applicable to the contract on a prospective basis. The wrap contracts provide for a variable crediting rate, which typically resets quarterly, and the issuer of the wrap contract provides assurance that future adjustments to the crediting rate cannot result in a crediting rate less than zero. The wrap contract crediting rate is typically based on the current yield-to-maturityof the covered investments, plus or minus an amortization of the difference between the market value and contract value of the covered investments over the duration of the covered investments at the time of computation. The crediting rate is affected by the change in the annual effective yield-to-maturityof the underlying securities, and is also affected by the differential between the contract value and the market value of the covered investments. In addition, changes in duration from reset period to reset period can affect the crediting rate. Certain events can limit the ability of the Plan to transact at contract value. Such events can include, but are not limited to, the following: (i) complete or partial Plan termination or merger with another plan; (ii) changes to the Plan’s prohibition on competing investment options or deletion of equity wash provisions; (iii) bankruptcy of BNSF or other BNSF events (e.g., divestitures or spin-offof a subsidiary) which cause a significant withdrawal from the Plan; or (iv) the failure of the Plan or Master Trust to qualify for exemption from federal income taxes or any required prohibited transaction exemption under ERISA. The Plan Administrator does not believe that the occurrence of any such event, which would limit the Plan’s ability to transact at contract value with participants, is probable. Investment contracts generally impose conditions on the Plan. If an event of default occurs and is not cured, the issuer may terminate the contract. These events may include: (i) a breach of material obligation under the contract; (ii) a material misrepresentation; or (iii) a material amendment to the Plan agreement that is not approved and accepted by the issuer. The Plan may terminate wrap contracts at any time with notice, subject to certain conditions.
