Our policy is to report loans that are 60 or more days past due, which equates to two or more payments missed, as delinquent. We do not accrue interest on loans 90 days past due, and any interest received on these loans is either applied to the principal or recorded in net investment income on our Consolidated Statements of Comprehensive Income (Loss) when received, depending on the assessment of the collectability of the loan. We resume accruing interest once a loan complies with all of its original terms or restructured terms. Mortgage loans deemed uncollectible are charged against the valuation allowance, and subsequent recoveries, if any, are credited to the valuation allowance.
Other assets and other liabilities on our Consolidated Balance Sheets include GLB features and remaining guaranteed interest and similar contracts that are carried at fair value, which may be reported in either other assets or other liabilities. The fair value of these items represents approximate exit price including an estimate for our NPR. Certain of these features have elements of both insurance benefits and embedded derivatives. Through our hybrid accounting approach, for reserve calculation purposes we assign product cash flows to the embedded derivative or insurance portion of the reserves based on the life-contingent nature of the benefits. We classify these GLB reserves embedded derivatives in Level 3 within the hierarchy levels described above in “Fair Value Measurement.” We report the insurance portion of the reserves in future contract benefits.
which the majority of account values are expected to run off, or 20 years. During 2012 and 2013, we completed reinsurance transactions whereby we ceded a closed block of UL contracts with secondary guarantees to LNBAR. We are recognizing the gains related to these transactions over a period of 30 years. During 2009, we completed a reinsurance transaction whereby we assumed a closed block of term contracts from First Penn-Pacific Life Insurance Company, a wholly-owned subsidiary of LNC. We are recognizing the gain related to this transaction over a period of 15 years.
The timing of revenue recognition as it relates to fees assessed on investment contracts is determined based on the nature of such fees. Asset-based fees, cost of insurance and contract administration charges are assessed on a daily or monthly basis and recognized as revenue as performance obligations are met, over the period underlying customer assets are owned or advisory services are provided. Percent of premium charges are assessed at the time of premium payment and recognized as revenue when assessed and earned. Certain amounts assessed that represent compensation for services to be provided in future periods are reported as unearned revenue and recognized in income over the periods benefited. Surrender charges are recognized upon surrender of a contract by the contract holder in accordance with contractual terms.
At the time of adoption, we had equity securities classified as AFS with a total carrying value of $246 million. We classified, prospectively, $110 million of equity securities within the scope of this ASU in a separate line on our Consolidated Balance Sheets. The remaining securities, consisting of $136 million of FHLB stock, are classified in other investments on our Consolidated Balance Sheets and carried at cost. The cumulative effect adjustment of adopting this ASU did not have a material impact on our consolidated financial condition or results of operations.
As described in Note 1, we use the loan-to-value and debt-service coverage ratios as credit quality indicators for our commercial mortgage loans on real estate (dollars in millions) as follows:
Our indexed annuity and IUL contracts permit the holder to elect an interest rate return or an equity market component, where interest credited to the contracts is linked to the performance of the S&P 500. Contract holders may elect to rebalance index options at renewal dates, either annually or biannually. As of each renewal date, we have the opportunity to re-price the indexed component by establishing participation rates, caps, spreads and specified rates, subject to contractual guarantees. We purchase call options that are highly correlated to the portfolio allocation decisions of our contract holders, such that we are economically hedged with respect to equity returns for the current reset period.
As of December 31, 2018, we did not have any exposure related to credit default swaps for which we are the seller.
We are exposed to credit losses in the event of non-performance by our counterparties on various derivative contracts and reflect assumptions regarding the credit or NPR. The NPR is based upon assumptions for each counterparty’s credit spread over the estimated weighted average life of the counterparty exposure, less collateral held. As of December 31, 2018, the NPR adjustment was less than $1 million. The credit risk associated with such agreements is minimized by entering into agreements with financial institutions with long-standing, superior performance records. Additionally, we maintain a policy of requiring derivative contracts to be governed by an International Swaps and Derivatives Association (“ISDA”) Master Agreement. We are required to maintain minimum ratings as a matter of routine practice in negotiating ISDA agreements. Under some ISDA agreements, we and LLANY have agreed to maintain certain financial strength or claims-paying ratings. A downgrade below these levels could result in termination of derivative contracts, at which time any amounts payable by us would be dependent on the market value of the underlying derivative contracts. In certain transactions, we and the counterparty have entered into a credit support annex requiring either party to post collateral when net exposures exceed pre-determined thresholds. These thresholds vary by counterparty and credit rating. The amount of such exposure is essentially the net replacement cost or market value less collateral held for such agreements with each counterparty if the net market value is in our favor. We did not have any exposure as of December 31, 2018 or 2017.
Our reinsurance operations were acquired by Swiss Re in December 2001 through a series of indemnity reinsurance transactions. As such, Swiss Re reinsured certain liabilities and obligations under the indemnity reinsurance agreements. As we are not relieved of our liability to the ceding companies for this business, the liabilities and obligations associated with the reinsured policies remain on our Consolidated Balance Sheets with a corresponding reinsurance receivable from Swiss Re, which totaled $1.5 billion and $1.9 billion as of December 31, 2018 and 2017, respectively. Swiss Re has funded a trust, with a balance of $2.4 billion as of December 31, 2018, to support this business. In addition to various remedies that we would have in the event of a default by Swiss Re, we continue to hold assets in support of certain of the transferred reserves. These assets consist of those reported as trading securities and certain mortgage loans. Our liabilities for funds withheld and embedded derivatives as of December 31, 2018, included $177 million and $24 million, respectively, related to the business sold to Swiss Re. In addition, the amounts recoverable from LNBAR were $2.5 billion and $2.1 billion as of December 31, 2018 and 2017, respectively. LNBAR has funded trusts to support the business ceded of which the balance in the trusts changes as a result of ongoing reinsurance activity and totaled $1.9 billion as of December 31, 2018.
We establish liabilities for litigation and regulatory loss contingencies when information related to the loss contingencies shows both that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. It is possible that some matters could require us to pay damages or make other expenditures or establish accruals in amounts that could not be estimated as of December 31, 2018. While the potential future charges could be material in the particular quarterly or annual periods in which they are recorded, based on information currently known by management, management does not believe any such charges are likely to have a material adverse effect on LNL’s financial condition.
For some matters, the Company is able to estimate a reasonably possible range of loss. For such matters in which a loss is probable, an accrual has been made. For such matters where a loss is believed to be reasonably possible, but not probable, no accrual has been made. Accordingly, the estimate contained in this paragraph reflects two types of matters. For some matters included within this estimate, an accrual has been made, but there is a reasonable possibility that an exposure exists in excess of the amount accrued. In these cases, the estimate reflects the reasonably possible range of loss in excess of the accrued amount. For other matters included within this estimation, no accrual has been made because a loss, while potentially estimable, is believed to be reasonably possible but not probable. In these cases, the estimate reflects the reasonably possible loss or range of loss. As of December 31, 2018, we estimate the aggregate range of reasonably possible losses to be up to approximately $50 million.
In re: Lincoln National COI Litigation, pending in the U.S. District Court for the Eastern District of Pennsylvania, Master File No. 2:16-cv-06605-GJP, is a consolidated litigation matter related to multiple putative class action filings that were consolidated by an order dated March 20, 2017. In addition to consolidating a number of existing matters, the order also covers any future cases filed in the same district related to the same subject matter. Plaintiffs own universal life insurance policies originally issued by Jefferson-Pilot (now LNL). Plaintiffs allege that LNL and LNC breached the terms of policyholders’ contracts by increasing non-guaranteed cost of insurance rates beginning in 2016. Plaintiffs seek to represent classes of policyowners and seek damages on their behalf. We are vigorously defending this matter.
LSH Co. and Wells Fargo Bank, National Association, as securities intermediary for LSH Co. v. Lincoln National Corporation and The Lincoln National Life Insurance Company, pending in the U.S. District Court for the Eastern District of Pennsylvania, No. 2:18-cv-05529, is a civil action filed on December 21, 2018. Plaintiffs own universal life insurance policies originally issued by Jefferson-Pilot (now LNL). Plaintiffs allege that LNL breached the terms of policyholders’ contracts when it increased non-guaranteed cost of insurance rates in 2016 and 2017. Because the majority of policies at issue experienced a rate change in 2016, we expect the case will be consolidated with the In re: Lincoln National COI Litigation and EFG Bank cases, discussed above. We are vigorously defending this matter.
State guaranty funds assess insurance companies to cover losses to contract holders of insolvent or rehabilitated companies. Mandatory assessments may be partially recovered through a reduction in future premium taxes in some states. We have accrued for expected assessments and the related reductions in future state premium taxes, which net to assessments (recoveries) of $(18) million and $(17) million as of December 31, 2018 and 2017, respectively.
See “Fair Value Measurement” in Note 1 for discussion on how we categorize our pension plans’ assets into the three-level fair value hierarchy. See “Financial Instruments Carried at Fair Value” in Note 22 for a summary of our fair value measurement of our pension plans’ assets by the three-level fair value hierarchy.
