The majority of the net balances are related to disability claims with long-tail payouts on which interest earned on assets backing liabilities is an integral part of pricing and reserving. Interest accrued on prior year reserves has been calculated on the opening reserve balance less one-half of the period's claim payments relative to prior years at our average reserve discount rate for the respective periods.

"Incurred Related to Prior Years - All Other Incurred" shown in the preceding chart includes the increase in benefits and change in reserves for future benefits resulting from the realization of previously unrealized investment gains and losses as a result of the Closed Block individual disability reinsurance agreement and reserve adjustments as discussed in the following paragraphs, which impact the comparability between the years presented. Excluding those adjustments, the variability exhibited year over year is primarily caused by the level of claim resolutions in the period relative to the long-term expectations reflected in the reserves. Our claim resolution rate assumption used in determining reserves is our expectation of the resolution rate we will experience over the life of the block of business and will vary from actual experience in any one period, both favorably and unfavorably.

2021 Reserve Assumption Updates

During the third quarter of 2021, we completed a review of policy and claim reserve adequacy, which incorporated our most recent experience and included a review of all material assumptions. Based on our analysis, during the third quarter of 2021, we updated our reserve assumptions and determined that our claim reserves should be reduced by $215.0 million in our Unum US group long-term disability product line due primarily to sustained improvement in claim recovery trends since our last assumption update. We also increased our claim reserves for our Closed Block long-term care and individual disability product lines by $2.1 million and $6.4 million, respectively, to reflect our current estimate of future benefit obligations. As a result, a net reduction of approximately $206.5 million, which can be primarily attributed to prior year incurred claims, impacts the results shown in the preceding chart. We increased policy reserves in our Closed Block group pension product line by $25.1 million as a result of this review which did not affect the results shown in the preceding chart.

Closed Block Individual Disability Reinsurance Transaction

In connection with the second phase of the Closed Block individual disability coinsurance agreement that closed in March 2021, we recorded a reinsurance recoverable of $990.0 million representing the ceded reserves related to the cohort of policies on claim status as of January 1, 2021 and an increase in benefits and change in reserves for future benefits of $133.1 million resulting from the realization of previously unrealized investment gains and losses recorded in accumulated other comprehensive income. See Note 12 for further discussion regarding the total impacts of the Closed Block individual disability reinsurance transaction.

Reconciliation

A reconciliation of policy and contract benefits and reserves for future policy and contract benefits as reported in our consolidated balance sheets to the liability for unpaid claims and claim adjustment expenses is as follows:

	September 30
	2021		2020
	(in millions of dollars)
Policy and Contract Benefits	$	1,920.4	$	1,801.6
Reserves for Future Policy and Contract Benefits	48,475.7		48,844.3
Total	50,396.1		50,645.9
Less:
Life Reserves for Future Policy and Contract Benefits	8,465.8		8,327.8
Accident and Health Active Life Reserves	13,016.9		12,478.5
Adjustment Related to Unrealized Investment Gains and Losses	5,143.9		6,971.3
Liability for Unpaid Claims and Claim Adjustment Expenses	$	23,769.5	$	22,868.3

The adjustment related to unrealized investment gains and losses reflects the changes that would be necessary to policyholder liabilities if the unrealized investment gains and losses related to the corresponding available-for-sale securities had been realized. Changes in this adjustment are reported as a component of other comprehensive income or loss.
