Note 1. Summary of Significant Accounting Policies

Basis of presentation – Loews Corporation is a holding company. Its subsidiaries are engaged in the following lines of business: commercial property and casualty insurance (CNA Financial Corporation (“CNA”), a 90% owned subsidiary); the operation of offshore oil and gas drilling rigs (Diamond Offshore Drilling, Inc. (“Diamond Offshore”), a 53% owned subsidiary); transportation and storage of natural gas and natural gas liquids (Boardwalk Pipeline Partners, LP (“Boardwalk Pipeline”), a 51% owned subsidiary); and the operation of a chain of hotels (Loews Hotels Holding Corporation (“Loews Hotels”), a wholly owned subsidiary). Unless the context otherwise requires, the terms “Company,” “Loews” and “Registrant” as used herein mean Loews Corporation excluding its subsidiaries and the term “Net income (loss) attributable to Loews Corporation” as used herein means Net income (loss) attributable to Loews Corporation shareholders.

Principles of consolidation – The Consolidated Financial Statements include all subsidiaries and intercompany accounts and transactions have been eliminated. The equity method of accounting is used for investments in associated companies in which the Company generally has an interest of 20% to 50%.

Accounting estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the related notes. Actual results could differ from those estimates.

Investments – The Company classifies its fixed maturity securities and equity securities as either available-for-sale or trading, and as such, they are carried at fair value. Short term investments are carried at fair value. Changes in fair value of trading securities are reported within Net investment income on the Consolidated Statements of Income. Changes in fair value related to available-for-sale securities are reported as a component of Other comprehensive income. Losses may be recognized within the Consolidated Statements of Income when a decline in value is determined by the Company to be other-than-temporary.

The cost of fixed maturity securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts, which are included in Net investment income on the Consolidated Statements of Income. The amortization of premium and accretion of discount for fixed maturity securities takes into consideration call and maturity dates that produce the lowest yield. In 2015, the Company changed its accounting principle as previously the amortization of premiums was to maturity. This change in estimate, effected by a change in accounting principle was adopted in the fourth quarter of 2015 and decreased Net investment income and the amortized cost of fixed maturity securities by $39 million in the Consolidated Statements of Income for the year ended December 31, 2015 and the Consolidated Balance Sheet as of December 31, 2015. The decrease to Net investment income included a $22 million cumulative adjustment relating to prior periods. The total adjustment decreased basic and diluted net income per share by $0.06 for the year ended December 31, 2015.

To the extent that unrealized gains on fixed income securities supporting long term care products and structured settlements not funded by annuities would result in a premium deficiency if those gains were realized, a related increase in Insurance reserves is recorded, net of tax and noncontrolling interests, as a reduction of net unrealized gains through Other comprehensive income (“Shadow Adjustments”). Shadow Adjustments decreased $87 million (after tax and noncontrolling interests) and $159 million (after tax and noncontrolling interests) for the years ended December 31, 2016 and 2015. As of December 31, 2016 and 2015, net unrealized gains on investments included in Accumulated other comprehensive income (“AOCI”) were correspondingly reduced by Shadow Adjustments of $909 million and $996 million (after tax and noncontrolling interests).

For asset-backed securities included in fixed maturity securities, the Company recognizes income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The amortized cost of high credit quality fixed rate securities is adjusted to the amount that would have existed had the new effective yield been applied since the acquisition of the securities. Such adjustments are reflected in Net investment income on the Consolidated Statements of Income. Interest income on lower rated and variable rate securities is determined using the prospective yield method.

The Company’s carrying value of investments in limited partnerships is its share of the net asset value of each partnership, as determined by the general partner. Certain partnerships for which results are not available on a timely basis are reported on a lag, primarily three months or less. These investments are accounted for under the equity method and changes in net asset values are recorded within Net investment income on the Consolidated Statements of Income.

Investments in derivative securities are carried at fair value with changes in fair value reported as a component of Investment gains (losses), Income (loss) from trading portfolio, or Other comprehensive income (loss), depending on their hedge designation. A derivative is typically defined as an instrument whose value is “derived” from an underlying instrument, index or rate, has a notional amount, requires little or no initial investment and can be net settled. Derivatives include, but are not limited to, the following types of investments: interest rate swaps, interest rate caps and floors, put and call options, warrants, futures, forwards, commitments to purchase securities, credit default swaps and combinations of the foregoing. Derivatives embedded within non-derivative instruments (such as call options embedded in convertible bonds) must be split from the host instrument when the embedded derivative is not clearly and closely related to the host instrument.

A security is impaired if the fair value of the security is less than its cost adjusted for accretion, amortization and previously recorded other-than-temporary impairment (“OTTI”) losses, otherwise defined as an unrealized loss. When a security is impaired, the impairment is evaluated to determine whether it is temporary or other-than-temporary.

Significant judgment is required in the determination of whether an OTTI loss has occurred for a security. CNA follows a consistent and systematic process for determining and recording an OTTI loss. CNA has established a committee responsible for the OTTI process referred to as the Impairment Committee. The Impairment Committee is responsible for evaluating all securities in an unrealized loss position on at least a quarterly basis.

The Impairment Committee’s assessment of whether an OTTI loss has occurred incorporates both quantitative and qualitative information. Fixed maturity securities that CNA intends to sell, or it more likely than not will be required to sell before recovery of amortized cost, are considered to be other-than-temporarily impaired and the entire difference between the amortized cost basis and fair value of the security is recognized as an OTTI loss in earnings. The remaining fixed maturity securities in an unrealized loss position are evaluated to determine if a credit loss exists. The factors considered by the Impairment Committee include: (i) the financial condition and near term and long term prospects of the issuer, (ii) whether the debtor is current on interest and principal payments, (iii) credit ratings of the securities and (iv) general market conditions and industry or sector specific outlook. CNA also considers results and analysis of cash flow modeling for asset-backed securities, and when appropriate, other fixed maturity securities.

The focus of the analysis for asset-backed securities is on assessing the sufficiency and quality of underlying collateral and timing of cash flows based on scenario tests. If the present value of the modeled expected cash flows equals or exceeds the amortized cost of a security, no credit loss is judged to exist and the asset-backed security is deemed to be temporarily impaired. If the present value of the expected cash flows is significantly less than amortized cost, the security is judged to be other-than-temporarily impaired for credit reasons and that shortfall, referred to as the credit component, is recognized as an OTTI loss in earnings. The difference between the adjusted amortized cost basis and fair value, referred to as the non-credit component, is recognized as OTTI in Other comprehensive income. In subsequent reporting periods, a change in intent to sell or further credit impairment on a security whose fair value has not deteriorated will cause the non-credit component originally recorded as OTTI in Other comprehensive income to be recognized as an OTTI loss in earnings.

CNA performs the discounted cash flow analysis using stressed scenarios to determine future expectations regarding recoverability. Significant assumptions enter into these cash flow projections including delinquency rates, probable risk of default, loss severity upon a default, over collateralization and interest coverage triggers and credit support from lower level tranches.

CNA applies the same impairment model as described above for the majority of its non-redeemable preferred stock securities on the basis that these securities possess characteristics similar to debt securities and that the issuers maintain their ability to pay dividends. For all other equity securities, in determining whether the security is other-than-temporarily impaired, the Impairment Committee considers a number of factors including, but not limited to: (i) the length of time and the extent to which the fair value has been less than amortized cost, (ii) the financial condition and near term prospects of the issuer, (iii) the intent and ability of CNA to retain its investment for a period of time sufficient to allow for an anticipated recovery in value and (iv) general market conditions and industry or sector specific outlook.

Joint venture investments – The Company has 20% to 50% interests in operating joint ventures related to hotel properties and had joint venture interests in the former Bluegrass Project, as discussed in Note 2, that are accounted for under the equity method. The Company’s investment in these entities was $217 million and $234 million for the years ended December 31, 2016 and 2015 and reported in Other assets on the Company’s Consolidated Balance Sheets. Equity income (loss) for these investments was $41 million, $43 million and $(62) million for the years ended December 31, 2016, 2015 and 2014 and reported in Other operating expenses on the Company’s Consolidated Statements of Income. Some of these investments are variable interest entities (“VIE”) as defined in the accounting guidance because the entities will require additional funding from each equity owner throughout the development and construction phase and are accounted for under the equity method since the Company is not the primary beneficiary. The maximum exposure to loss for the VIE investments is $337 million, consisting of the amount of the investment and debt guarantees.

The following tables present summarized financial information for these joint ventures:


Year Ended December 31			2016		2015

(In millions)

Total assets			$	1,749	$	1,577
Total liabilities				1,444		1,231

Year Ended December 31	2016		2015		2014


Revenues	$	693	$	606	$	491
Net income		80		71		32

Hedging – The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedging transactions. The Company also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in fair value or cash flows of hedged items and whether those derivatives may be expected to remain highly effective in future periods. When it is determined that a derivative for which hedge accounting has been designated is not (or ceases to be) highly effective, the Company discontinues hedge accounting prospectively. See Note 3 for additional information on the Company’s use of derivatives.

Securities lending activities – The Company lends securities for the purpose of enhancing income or to finance positions to unrelated parties who have been designated as primary dealers by the Federal Reserve Bank of New York. Borrowers of these securities must deposit and maintain collateral with the Company of no less than 100% of the fair value of the securities loaned. U.S. Government securities and cash are accepted as collateral. The Company maintains effective control over loaned securities and, therefore, continues to report such securities as investments on the Consolidated Balance Sheets.

Securities lending is typically done on a matched-book basis where the collateral is invested to substantially match the term of the loan. This matching of terms tends to limit risk. In accordance with the Company’s lending agreements, securities on loan are returned immediately to the Company upon notice. Collateral is not reflected as an asset of the Company. There was no collateral held at December 31, 2016 and 2015.

Revenue recognition – Premiums on property and casualty insurance contracts are recognized in proportion to the underlying risk insured and are principally earned ratably over the duration of the policies. Premiums on long term care contracts are earned ratably over the policy year in which they are due. The reserve for unearned premiums represents the portion of premiums written relating to the unexpired terms of coverage.

Insurance receivables include balances due currently or in the future, including amounts due from insureds related to losses under high deductible policies, and are presented at unpaid balances, net of an allowance for doubtful accounts. Amounts are considered past due based on policy payment terms. The allowance is determined based on periodic evaluations of aged receivables, management’s experience and current economic conditions. Insurance receivables and any related allowance are written off after collection efforts are exhausted or a negotiated settlement is reached.

Property and casualty contracts that are retrospectively rated contain provisions that result in an adjustment to the initial policy premium depending on the contract provisions and loss experience of the insured during the experience period. For such contracts, CNA estimates the amount of ultimate premiums that it may earn upon completion of the experience period and recognizes either an asset or a liability for the difference between the initial policy premium and the estimated ultimate premium. CNA adjusts such estimated ultimate premium amounts during the course of the experience period based on actual results to date. The resulting adjustment is recorded as either a reduction of or an increase to the earned premiums for the period.

Contract drilling revenue from dayrate drilling contracts is recognized as services are performed. In connection with such drilling contracts, Diamond Offshore may receive fees (either lump-sum or dayrate) for the mobilization of equipment. These fees are earned as services are performed over the initial term of the related drilling contracts. Absent a contract, mobilization costs are recognized currently. From time to time, Diamond Offshore may receive fees from its customers for capital improvements to their rigs. Diamond Offshore defers such fees received and recognizes these fees into revenue on a straight-line basis over the period of the related drilling contract. Diamond Offshore capitalizes the costs of such capital improvements and depreciates them over the estimated useful life of the improvement.

Revenues from transportation and storage services are recognized in the period the service is provided based on contractual terms and the related transported and stored volumes. The majority of Boardwalk Pipeline’s operating subsidiaries are subject to Federal Energy Regulatory Commission (“FERC”) regulations and, accordingly, certain revenues collected may be subject to possible refunds to its customers. An estimated refund liability is recorded considering regulatory proceedings, advice of counsel and estimated total exposure.

Claim and claim adjustment expense reserves – Claim and claim adjustment expense reserves, except reserves for structured settlements not associated with asbestos and environmental pollution (“A&EP”), workers’ compensation lifetime claims and long term care claims, are not discounted and are based on (i) case basis estimates for losses reported on direct business, adjusted in the aggregate for ultimate loss expectations; (ii) estimates of incurred but not reported losses; (iii) estimates of losses on assumed reinsurance; (iv) estimates of future expenses to be incurred in the settlement of claims; (v) estimates of salvage and subrogation recoveries and (vi) estimates of amounts due from insureds related to losses under high deductible policies. Management considers current conditions and trends as well as past CNA and industry experience in establishing these estimates. The effects of inflation, which can be significant, are implicitly considered in the reserving process and are part of the recorded reserve balance. Ceded claim and claim adjustment expense reserves are reported as a component of Receivables on the Consolidated Balance Sheets.

Claim and claim adjustment expense reserves are presented net of anticipated amounts due from insureds related to losses under deductible policies of $1.2 billion as of December 31, 2016 and 2015. A significant portion of these amounts are supported by collateral. CNA also has an allowance for uncollectible deductible amounts, which is presented as a component of the allowance for doubtful accounts included in Receivables on the Consolidated Balance Sheets.

Structured settlements have been negotiated for certain property and casualty insurance claims. Structured settlements are agreements to provide fixed periodic payments to claimants. CNA’s obligations for structured settlements not funded by annuities are included in claim and claim adjustment expense reserves and carried at present values determined using interest rates ranging from 5.5% to 8.0% at December 31, 2016 and 2015. At December 31, 2016 and 2015, the discounted reserves for unfunded structured settlements were $544 million and $560 million, net of discount of $841 million and $880 million. For the years ended December 31, 2016, 2015 and 2014, the amount of interest recognized on the discounted reserves of unfunded structured settlements was $42 million, $42 million and $43 million. This interest accretion is presented as a component of Insurance claims and policyholders’ benefits on the Consolidated Statements of Income but is excluded from the disclosure of prior year development.

Workers’ compensation lifetime claim reserves are calculated using mortality assumptions determined through statutory regulation and economic factors. At December 31, 2016 and 2015, workers’ compensation lifetime claim reserves are discounted at a 3.5% interest rate. As of December 31, 2016 and 2015, the discounted reserves for workers’ compensation lifetime claim reserves were $371 million and $396 million, net of discount of $202 million and $218 million. For the years ended December 31, 2016, 2015 and 2014, the amount of interest accretion recognized on the discounted reserves of workers’ compensation lifetime claim reserves was $17 million, $20 million and $22 million.

Long term care claim reserves are calculated using mortality and morbidity assumptions based on CNA and industry experience. Long term care claim reserves are discounted at interest rates ranging from 4.5% to 6.8% at December 31, 2016 and 2015. At December 31, 2016 and 2015, such discounted reserves totaled $2.2 billion, net of discount of $529 million and $435 million.

Future policy benefits reserves – Future policy benefits reserves represent the active life reserves related to CNA’s long term care policies and are computed using the net level premium method, which incorporates actuarial assumptions as to morbidity, persistency, discount rate and expenses. Expense assumptions primarily relate to claim adjudication. Actuarial assumptions generally vary by plan, age at issue policy duration and gender. The initial assumptions are determined at issuance, include a margin for adverse deviation and are locked in throughout the life of the contract unless a premium deficiency develops. If a premium deficiency emerges, the assumptions are unlocked and deferred acquisition costs, if any, and the future policy benefits reserves are adjusted. The December 31, 2015 gross premium valuation (“GPV”) indicated a premium deficiency of $296 million. The indicated premium deficiency necessitated a charge to income that was effected by the write off of the entire long term care deferred acquisition cost asset of $289 million and an increase to active life reserves of $7 million. As a result, the long term care active life reserves carried as of December 31, 2015 represent management’s best estimate assumptions at that date with no margin for adverse deviation. The December 31, 2016 GPV indicated the carried reserves were sufficient, therefore there was no unlocking of assumptions. Interest rates for long term care active life reserves range from 6.6% to 7.0% as of December 31, 2016 and 2015.

Guaranty fund and other insurance-related assessments – Liabilities for guaranty fund and other insurance-related assessments are accrued when an assessment is probable, when it can be reasonably estimated and when the event obligating the entity to pay an imposed or probable assessment has occurred. Liabilities for guaranty funds and other insurance-related assessments are not discounted and are included as part of Other liabilities on the Consolidated Balance Sheets. As of December 31, 2016 and 2015, the liability balances were $125 million and $129 million.

Reinsurance – Reinsurance accounting allows for contractual cash flows to be reflected as premiums and losses. To qualify for reinsurance accounting, reinsurance agreements must include risk transfer. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity.

Reinsurance receivables related to paid losses are presented at unpaid balances. Reinsurance receivables related to unpaid losses are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefits reserves. Reinsurance receivables are reported net of an allowance for doubtful accounts on the Consolidated Balance Sheets. The cost of reinsurance is primarily accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies or over the reinsurance contract period. The ceding of insurance does not discharge the primary liability of CNA.

CNA has established an allowance for doubtful accounts on reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. The allowance for doubtful accounts on reinsurance receivables is estimated on the basis of periodic evaluations of balances due from reinsurers, reinsurer solvency, management’s experience and current economic conditions. Reinsurer financial strength ratings are updated and reviewed on an annual basis or sooner if CNA becomes aware of significant changes related to a reinsurer. Because billed receivables generally approximate 3% or less of total reinsurance receivables, the age of the reinsurance receivables related to paid losses is not a significant input into the allowance analysis. Changes in the allowance for doubtful accounts on reinsurance receivables are presented as a component of Insurance claims and policyholders’ benefits on the Consolidated Statements of Income.

Amounts are considered past due based on the reinsurance contract terms. Reinsurance receivables related to paid losses and any related allowance are written off after collection efforts have been exhausted or a negotiated settlement is reached with the reinsurer. Reinsurance receivables related to paid losses from insolvent insurers are written off when the settlement due from the estate can be reasonably estimated. At the time reinsurance receivables related to paid losses are written off, any required adjustment to reinsurance receivables related to unpaid losses is recorded as a component of Insurance claims and policyholders’ benefits on the Consolidated Statements of Income.

Reinsurance contracts that do not effectively transfer the economic risk of loss on the underlying policies are recorded using the deposit method of accounting, which requires that premium paid or received by the ceding company or assuming company be accounted for as a deposit asset or liability. CNA had $3 million recorded as deposit assets at December 31, 2016 and 2015, and $6 million and $8 million recorded as deposit liabilities as of December 31, 2016 and 2015. Income on reinsurance contracts accounted for under the deposit method is recognized using an effective yield based on the anticipated timing of payments and the remaining life of the contract. When the anticipated timing of payments changes, the effective yield is recalculated to reflect actual payments to date and the estimated timing of future payments. The deposit asset or liability is adjusted to the amount that would have existed had the new effective yield been applied since the inception of the contract.

A loss portfolio transfer is a retroactive reinsurance contract. If the cumulative claim and allocated claim adjustment expenses ceded under a loss portfolio transfer exceed the consideration paid, the resulting gain from such excess is deferred and amortized into earnings in future periods in proportion to actual recoveries under the loss portfolio transfer. In any period in which there is a gain position and a revised estimate of claim and allocated claim adjustment expenses, a portion of the deferred gain is cumulatively recognized in earnings as if the revised estimate was available at the inception date of the loss portfolio transfer.

Deferred acquisition costs – Deferrable acquisition costs include commissions, premium taxes and certain underwriting and policy issuance costs which are incremental direct costs of successful contract acquisitions. Acquisition costs related to property and casualty business are deferred and amortized ratably over the period the related premiums are earned. Deferred acquisition costs are presented net of ceding commissions and other ceded acquisition costs.

CNA evaluates deferred acquisition costs for recoverability. Anticipated investment income is considered in the determination of the recoverability of deferred acquisition costs. Adjustments, if necessary, are recorded in current period results of operations.

Deferred acquisition costs related to long term care contracts issued prior to January 1, 2004 include costs which vary with and are primarily related to the acquisition of business. As noted under Future policy benefits reserves, all of the long term care deferred acquisition costs of $289 million were written off as of December 31, 2015 in recognition of a premium deficiency.

Investments in life settlement contracts and related revenue recognition – Prior to 2002, CNA purchased investments in life settlement contracts. CNA obtained the ownership and beneficiary rights of an underlying life insurance policy through a life settlement contract with the owner of the life insurance contract.

CNA accounts for its investments in life settlement contracts using the fair value method. Under the fair value method, each life settlement contract is carried at its fair value at the end of each reporting period. The change in fair value estimated through CNA’s internal valuation process, life insurance proceeds received and periodic maintenance costs, such as premiums, necessary to keep the underlying policy in force, are recorded in Other revenues on the Consolidated Statements of Income. The increase in fair value recognized in Other revenues for the years ended December 31, 2016, 2015 and 2014 on contracts still held was $7 million, $1 million and $8 million. The gains recognized during the years ended December 31, 2016, 2015 and 2014 on contracts that settled were $8 million, $24 million and $25 million.

In December of 2016, CNA reached agreement on terms to sell the entire portfolio of life settlement contracts to a third party. CNA expects to consummate this transaction in 2017. As a result, the portfolio was determined to be held for sale as of December 31, 2016. Therefore, the contracts were measured at the lower of the carrying amount or the fair value per the agreed terms, resulting in a $10 million loss recognized within Other operating expenses. As of December 31, 2016, there were 526 life settlement contracts with a total fair value of $58 million, included in Other assets on the Consolidated Balance Sheets, and a face value of $285 million.

Goodwill – Goodwill represents the excess of purchase price over fair value of net assets of acquired entities. Goodwill is tested for impairment annually or when certain triggering events require additional tests. Subsequent reversal of a goodwill impairment charge is not permitted.

Property, plant and equipment – Property, plant and equipment is carried at cost less accumulated depreciation and amortization. Depreciation is computed principally by the straight-line method over the estimated useful lives of the various classes of properties. Leaseholds and leasehold improvements are depreciated or amortized over the terms of the related leases (including optional renewal periods where appropriate) or the estimated lives of improvements, if less than the lease term.

The principal service lives used in computing provisions for depreciation are as follows:


	Years
Pipeline equipment		30 to 50
Offshore drilling equipment		15 to 30
Other		3 to 40

Impairment of long-lived assets –Long-lived assets are reviewed for impairment when changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets and intangibles with finite lives, under certain circumstances, are reported at the lower of carrying amount or fair value. Assets to be disposed of and assets not expected to provide any future service potential to the Company are recorded at the lower of carrying amount or fair value less cost to sell.

Income taxes – The Company and its eligible subsidiaries file a consolidated tax return. Deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities, based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on deferred tax assets and liabilities is recognized in income in the period in which such change is enacted. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is established for any portion of a deferred tax asset that management believes may not be realized.

The Company recognizes uncertain tax positions that it has taken or expects to take on a tax return. The tax benefit of a qualifying position is the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority having full knowledge of all relevant information. See Note 10 for additional information on the provision for income taxes.

Pension and postretirement benefits – The Company recognizes the overfunded or underfunded status of its defined benefit plans in Other assets or Other liabilities in the Consolidated Balance Sheets. Changes in funded status related to prior service costs and credits and actuarial gains and losses are recognized in the year in which the changes occur through Accumulated other comprehensive income (loss). The Company measures its benefit plan assets and obligations at December 31. Annual service cost, interest cost, expected return on plan assets, amortization of prior service costs and credits and amortization of actuarial gains and losses are recognized in the Consolidated Statements of Income.

Stock-based compensation – The Company records compensation expense upon issuance, modification or cancellation of all share-based payment awards granted, primarily on a straight-line basis over the requisite service period, generally three to four years. Stock Appreciation Rights (“SARs”) are valued using the Black-Scholes option pricing model. The application of this valuation model involves assumptions that are judgmental and highly sensitive. These assumptions include the term that the awards are expected to be outstanding, an estimate of the volatility of the underlying stock price, applicable risk-free interest rates and the dividend yield of the Company’s stock. Restricted Stock Units (“RSUs”) are valued using the grant-date fair value of the Company’s stock.

Net income per share – Companies with complex capital structures are required to present basic and diluted net income per share. Basic net income per share excludes dilution and is computed by dividing net income attributable to common stock by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

For each of the years ended December 31, 2016, 2015 and 2014, approximately 0.4 million, 0.3 million and 0.6 million potential shares attributable to issuances and exercises under the Loews Corporation 2016 Incentive Compensation Plan and the prior plan were included in the calculation of diluted net income per share. For those same periods, approximately 3.7 million, 4.8 million and 2.3 million shares attributable to employee stock-based compensation awards were not included in the calculation of diluted net income per share because the effect would have been antidilutive.

Foreign currency – Foreign currency translation gains and losses are reflected in Shareholders’ equity as a component of Accumulated other comprehensive income (loss). The Company’s foreign subsidiaries’ balance sheet accounts are translated at the exchange rates in effect at each reporting date and income statement accounts are translated at the average exchange rates during the reporting period. Foreign currency transaction losses of $21 million, $8 million and $22 million for the years ended December 31, 2016, 2015 and 2014 were included in the Consolidated Statements of Income.

Regulatory accounting – The majority of Boardwalk Pipeline’s operating subsidiaries are regulated by FERC. GAAP for regulated entities requires Texas Gas Transmission, LLC (“Texas Gas”), a wholly owned subsidiary of Boardwalk Pipeline, to report certain assets and liabilities consistent with the economic effect of the manner in which independent third party regulators establish rates. Effective April 1, 2016, Gulf South Pipeline, LP (“Gulf South”), a wholly owned subsidiary of Boardwalk Pipeline, implemented a fuel tracker pursuant to a FERC rate case settlement, for which Gulf South applies regulatory accounting. Accordingly, certain costs and benefits are capitalized as regulatory assets and liabilities in order to provide for recovery from or refund to customers in future periods. Other than as described for Texas Gas and Gulf South, regulatory accounting is not applicable to Boardwalk Pipeline’s other FERC regulated entities or operations.

Supplementary cash flow information – Cash payments made for interest on long term debt, net of capitalized interest, amounted to $511 million, $513 million and $501 million for the years ended December 31, 2016, 2015 and 2014. Cash payments for federal, foreign, state and local income taxes amounted to $114 million, $110 million and $189 million for the years ended December 31, 2016, 2015 and 2014. Investing activities exclude $18 million and $3 million of accrued capital expenditures for the years ended December 31, 2016 and 2015 and include $14 million of previously accrued capital expenditures for the year ended December 31, 2014.

Accounting changes – In April of 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The updated accounting guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, rather than as a deferred asset. As required, the Company’s Consolidated Balance Sheet has been retrospectively adjusted to reflect the effect of the adoption of the updated accounting guidance, which resulted in a decrease of $23 million in Other assets and Long term debt at December 31, 2015.

In May of 2015, the FASB issued ASU 2015-09, “Financial Services – Insurance (Topic 944): Disclosures about Short-Duration Contracts.” The updated accounting guidance requires enhanced disclosures to provide additional information about insurance liabilities for short-duration contracts. The guidance is effective for annual periods beginning after December 15, 2015 and for interim periods beginning after December 15, 2016. The Company has adopted the change in disclosure requirements for short-duration contracts.

Recently issued ASUs – In May of 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” The core principle of the new accounting guidance is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new accounting guidance provides a five-step analysis of transactions to determine when and how revenue is recognized and requires enhanced disclosures about revenue. In August of 2015, the FASB formally amended the effective date of this update to annual reporting periods beginning after December 15, 2017, including interim periods. The guidance can be adopted either retrospectively or with a cumulative effect adjustment at the date of adoption. The Company expects the updated guidance will not have a material impact on its consolidated financial statements.

In January of 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The updated accounting guidance requires changes to the reporting model for financial instruments. The guidance is effective for interim and annual periods beginning after December 15, 2017. The Company is currently evaluating the effect the guidance will have on its consolidated financial statements, and expects the primary change to be the requirement for equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income.

In February of 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” The updated guidance requires lessees to recognize lease assets and lease liabilities for most operating leases. In addition, the updated guidance requires that lessors separate lease and nonlease components in a contract in accordance with the new revenue guidance in ASU 2014-09. The updated guidance is effective for interim and annual periods beginning after December 15, 2018. The Company is currently evaluating the effect the updated guidance will have on its consolidated financial statements.

In June of 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The updated accounting guidance requires changes to the recognition of credit losses on financial instruments not accounted for at fair value through net income. The guidance is effective for interim and annual periods beginning after December 15, 2019. The Company is currently evaluating the effect the guidance will have on its consolidated financial statements, and expects the primary changes to be the use of the expected credit loss model for the mortgage loan portfolio and reinsurance receivables and the presentation of credit losses within the available-for-sale fixed maturities portfolio through an allowance method rather than as a direct write-down. The expected credit loss model will require a financial asset to be presented at the net amount expected to be collected. The allowance method for available-for-sale debt securities will allow the Company to record reversals of credit losses if the estimate of credit losses declines.
