Dispositions of $63 million in 2021 mainly relate to the sale of our agricultural asset portfolio.

The carrying values are based on external appraisals completed annually as at December 31. The appraisals utilize a combination of the discounted cash flow and sales comparison approaches to arrive at the estimated value. The significant unobservable inputs (Level 3) included in the discounted cash flow models used when determining the fair value of standing timber and agricultural assets include:

Valuation Techniques	Significant Unobservable Inputs	Relationship of Unobservable Inputs to Fair Value	Mitigating Factors
Discounted cash flow analysis	•Future cash flows	•Increases (decreases) in future cash flows increase (decrease) fair value	•Increases (decreases) in cash flows tend to be accompanied by increases (decreases) in discount rates that may offset changes in fair value from cash flows
	•Timber / agricultural prices	•Increases (decreases) in price increase (decrease) fair value	•Increases (decreases) in price tend to be accompanied by increases (decreases) in discount rates that may offset changes in fair value from price
	•Discount rate /terminal capitalization rate	•Increases (decreases) in discount rate or terminal capitalization rate decrease (increase) fair value	•Decreases (increases) in discount rates or terminal capitalization rates tend to be accompanied by increases (decreases) in cash flows that may offset changes in fair value from rates
	•Exit Date	•Increases (decreases) in exit date decrease (increase) fair value	•Increases (decreases) in the exit date tend to be the result of changing cash flow profiles that may result in higher (lower) growth in cash flows prior to stabilizing in the terminal year

As at December 31, 2021, there are no sustainable resources in our accounts receivable and other balance. Key valuation assumptions in the prior year included a weighted-average discount and terminal capitalization rate of 4.6% and terminal valuation dates of up to 18 years. Timber and agricultural asset prices were based on a combination of forward prices available in the market and price forecasts.
