[1] | We classify insurance contracts as Level 3 as there is limited activity or less observable inputs into valuation models, including current interest rates and estimated prepayment, default and recovery rates on the underlying portfolio or structured investment vehicle. The insurance contracts are valued using the plan’s own assumptions about the assumptions market participants would use in pricing the assets based on the best information available, such as investment manager pricing. Significant changes to assumptions or unobservable inputs in the valuation of our Level 3 instruments would not have a significant impact to our consolidated financial statements.
[2] | Funds that are measured at fair value using the net asset value (NAV) per share practical expedient have not been categorized in the fair value hierarchy. The amounts presented above are intended to permit reconciliation of the fair value hierarchy to the fair value of total plan assets in order to determine the amounts included in Other Liabilities in the Consolidated Balance Sheets.
