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 year’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.

Closed Block Individual Disability Reinsurance Transaction

In connection with the first phase of the Closed Block individual disability coinsurance agreement that closed in December 2020, we recorded a reinsurance recoverable of $6,141.5 million representing the ceded reserves related to the cohort of policies on claim status as of July 1, 2020 (DLR cohort) and an increase in benefits and change in reserves for future benefits of $1,284.5 million resulting from the realization of previously unrealized investment gains and losses recorded in accumulated other comprehensive income. These impacts are reflected in the chart shown above and the reconciliation shown below.

2020 Long-term Care Reserve Increase

During the fourth quarter of 2020, we completed a review of policy reserve adequacy, which incorporated our most recent experience and included a review of all material assumptions. Based on our analysis, during the fourth quarter of 2020, we updated our interest rate and premium rate increase reserve assumptions and determined that our gross long-term care policy and claim reserves should be increased by $151.5 million, of which $7.0 million was related to our liability for unpaid claims and claims adjustment expenses, which can be primarily attributed to prior year incurred claims, thereby impacting the results shown in the preceding chart.

2018 Long-term Care Reserve Increase

During the third quarter of 2018, we completed our annual review of policy reserve adequacy, which incorporated our most recent experience and included a review of all assumptions. Based on our analysis, during the third quarter of 2018, we updated our reserve assumptions and determined that our policy and claim reserves should be increased by $750.8 million of which, approximately $236 million was related to our liability for unpaid claims and claims adjustment expenses, which can be primarily attributed to prior year incurred claims, thereby impacting the results shown in the preceding chart.

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:

	December 31
	2020		2019		2018
	(in millions of dollars)
Policy and Contract Benefits	$	1,855.4	$	1,745.5	$	1,695.7
Reserves for Future Policy and Contract Benefits	49,653.0		47,780.1		44,841.9
Total	51,508.4		49,525.6		46,537.6
Less:
Life Reserves for Future Policy and Contract Benefits	8,371.7		8,435.7		8,330.9
Accident and Health Active Life Reserves	12,730.9		12,210.1		11,837.4
Adjustment Related to Unrealized Investment Gains and Losses	6,225.6		5,803.1		3,220.3
Liability for Unpaid Claims and Claim Adjustment Expenses	$	24,180.2	$	23,076.7	$	23,149.0

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.
