The funds held in the QSF Trust would be available to provide funding for the Section 524(g) Trust upon effectiveness of the Plan. If approved by the Bankruptcy Court and other conditions are satisfied, the QSF Trust is expected to be funded prior to January 31, 2022. At this point in the Chapter 11 cases of Aldrich and Murray, it is not possible to predict whether the Bankruptcy Court will approve the terms of the Plan, what the extent of the asbestos liability will be or how long the Chapter 11 cases will last.

Inputs and Valuation Techniques [Table] Fair Value Measurement Inputs and Valuation Techniques [Table] Deferred and noncurrent income taxes Deferred Tax Liabilities And Other Tax Liabilities Noncurrent Represents the noncurrent portion of deferred and other tax liabilities. Deferred tax liabilities result from applying the applicable tax rate to net taxable temporary differences pertaining to each jurisdiction to which the entity is obligated to pay income tax. A noncurrent taxable temporary difference is a difference between the tax basis and the carrying amount of a noncurrent asset or liability in the financial statements prepared in accordance with generally accepted accounting principles. In a classified statement of financial position, an enterprise separates deferred tax liabilities and assets into a current amount and a noncurrent amount. Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting. A deferred tax liability or asset that is not related to an asset or liability for financial reporting, including deferred tax assets related to carryforwards, are classified according to the expected reversal date of the temporary difference.
