W. R. Berkley and its subsidiaries own or lease office buildings or office space suitable to conduct their operations. At December 31, 2017, the Company had aggregate office space of 3,816,471 square feet, of which 1,096,493 were owned and 2,719,979 were leased.
The Company’s profitability is also affected by its investment income and investment gains. The Company’s invested assets are invested principally in fixed maturity securities. The return on fixed maturity securities is affected primarily by general interest rates, as well as the credit quality and duration of the securities. Returns available on fixed maturity investments have been at historically low levels in recent years.
The Company also invests in equity securities, merger arbitrage securities, investment funds (including energy related funds), private equity, loans and real estate related assets. The Company's investments in investment funds and its other alternative investments have experienced, and the Company expects to continue to experience, greater fluctuations in investment income.
The Tax Cuts and Jobs Act of 2017 (the Tax Act) was enacted on December 22, 2017. The Tax Act provides for a reduction of the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018. The Tax Act also provides for a mandatory repatriation of foreign earnings, which requires companies to pay a one-time tax on the unremitted accumulated earnings of their foreign subsidiaries. The Company has calculated the effects of the Tax Act as of December 31, 2017 and has included in its financial statements provisional estimates of its impact. The Company anticipates further guidance will be forthcoming and will continue to review and refine its calculations as guidance is provided and additional analysis of the Company's information is completed.
Commencing with the first quarter 2017, the Company reclassified two businesses from the Insurance segment to the Reinsurance segment. Reclassifications have been made to the Company's 2016 and earlier presented financial information to conform with this presentation.
Approximately $1.7 billion, or 17%, of the Company’s net loss reserves as of December 31, 2017 relate to the Reinsurance segment. There is a higher degree of uncertainty and greater variability regarding estimates of assumed loss reserves because those estimates are based, in part, upon information received from ceding companies. If information received from ceding companies is not timely or correct, the Company’s estimate of ultimate losses may not be accurate. Furthermore, due to delayed reporting of claim information by ceding companies, the claim settlement tail for assumed reinsurance is extended. Management considers the impact of delayed reporting in its selection of assumed loss development factors.
Reserves for excess and assumed workers’ compensation business are net of an aggregate net discount of $591 million and $640 million as of December 31, 2017 and 2016, respectively.
For professional liability business, adverse development was primarily related to unexpected large directors & officers ("D&O") liability losses at one of our U.S. operating units, and large professional indemnity and D&O losses in the U.K. The adverse development stemmed mainly from accident years 2013 through 2016 in the U.S. and 2011 through 2016 in the U.K.
The following table provides a summary of fixed maturity securities in an unrealized loss position as of December 31, 2017:
Common Stocks - At December 31, 2017, there were three common stocks in an unrealized loss position with an aggregate fair value of $18.6 million and a gross unrealized loss of $2.0 million. Based on management's view of these securities, the Company does not consider the common stocks to be OTTI. For the year ended December 31, 2017, there were no OTTI for common stocks. OTTI for common stocks for the year ended December 31, 2016 were $18.1 million.
Independent pricing services - Substantially all of the Company’s fixed maturity securities available for sale were priced by independent pricing services (generally one U.S. pricing service plus additional pricing services with respect to a limited number of foreign securities held by the Company). The prices provided by the independent pricing services are generally based on observable market data in active markets (e.g., broker quotes and prices observed for comparable securities). The determination of whether markets are active or inactive is based upon the volume and level of activity for a particular asset class. The Company reviews the prices provided by pricing services for reasonableness based upon current trading levels for similar securities. If the prices appear unusual to the Company, they are re-examined and the value is either confirmed or revised. In addition, the Company periodically performs independent price tests of a sample of securities to ensure proper
valuation and to verify our understanding of how securities are priced. As of December 31, 2017, the Company did not make any adjustments to the prices provided by the pricing services. Based upon the Company’s review of the methodologies used by the independent pricing services, these securities were classified as Level 2.
Following is a summary of gross and net premiums written, net premiums earned, loss ratios (losses and loss expenses incurred expressed as a percentage of net premiums earned), expense ratios (underwriting expenses expressed as a percentage of net premiums earned) and GAAP combined ratios (sum of loss ratio and expense ratio) for each of our business segments for the years ended December 31, 2017 and 2016. The GAAP combined ratio represents a measure of underwriting profitability, excluding investment income. A GAAP combined ratio in excess of 100 indicates an underwriting loss; a number below 100 indicates an underwriting profit.
The Company reported net income of $549 million in 2017 compared to $602 million in 2016. The 9% decrease in net income was primarily due to a decrease in after-tax underwriting income of $98 million (mainly driven by increased catastrophe losses from hurricanes Harvey, Irma, and Maria, two earthquakes in Mexico, and wildfires in California), an after-tax increase of $18 million in net foreign currency losses, an after-tax decrease in income from non-insurance businesses of $9 million, an increase in after-tax interest expense of $4 million, and an increase in after-tax other expenses of $7 million, partially offset by an increase in after-tax net investment gains of $45 million, a net benefit from tax reform of $21 million, an increase in after-tax net investment income of $8 million, an after-tax increase of $3 million in service fee income and an increase in income from other various sources of $6 million. The number of weighted average diluted shares remained relatively unchanged for 2017 and 2016.
Net premiums written were $6,261 million in 2017, a decrease of 3% from $6,424 million in 2016. Ceded reinsurance premiums as a percentage of gross written premiums were 16% in 2017 and 15% in 2016.
Net Realized Gains on Investment Sales. The Company buys and sells securities and other investment assets on a regular basis in order to maximize its total return on investments. Decisions to sell securities and other investment assets are based on management’s view of the underlying fundamentals of specific investments as well as management’s expectations regarding interest rates, credit spreads, currency values and general economic conditions. Net realized gains on investment sales were $336 million in 2017 compared with $285 million in 2016. In 2017, realized gains were primarily related to the sale of an investment in an office building located in Washington, D.C. and the sale of some shares of a publicly traded common stock. In 2016, realized gains were primarily related to the sale of Aero Precision Industries and the sale of some shares of a publicly traded common stock.
Other-Than-Temporary Impairments. The cost of securities is adjusted where appropriate to include a provision for a decline in value that is considered to be other-than-temporary. There were no other-than-temporary impairments in 2017 as compared to $18 million in 2016 primarily related to common stocks.
Losses and Loss Expenses. Losses and loss expenses increased to $4,002 million in 2017 from $3,846 million in 2016. The consolidated loss ratio was 63.4% in 2017 and 61.1% in 2016. Catastrophe losses, net of reinsurance recoveries and reinstatement premiums, were $184 million in 2017 compared with $105 million in 2016, an increase of 1.2 loss ratio points. Favorable prior year reserve development (net of premium offsets) was $37 million in 2017 compared with $59 million in 2016, a difference of 0.3 loss ratio points (see "- Critical Accounting Estimates - Reserves for Losses and Loss Expenses"). The loss ratio excluding catastrophe losses and prior year reserve development increased 0.8 points to 61.1% in 2017 from 60.3% in 2016.
A summary of loss ratios in 2017 compared with 2016 by business segment follows:
Other costs and expenses represent general and administrative expenses of the parent company and other expenses not allocated to business segments, including the cost of certain long-term incentive plans and new business ventures. Other costs and expenses increased to $191 million in 2017 from $179 million in 2016 primarily because of startup costs for new business ventures.
Net Income to Common Stockholders. The following table presents the Company’s net income to common stockholders and net income per diluted share for the years ended December 31, 2016 and 2015.
The Company reported net income of $602 million in 2016 compared to $504 million in 2015. The 20% increase in net income was primarily due to increases in after-tax net investment gains of $114 million, after-tax net investment income of $34 million and after-tax foreign currency gains of $8 million, partially offset by a decrease in after-tax underwriting income of $13 million, an increase in after-tax interest expense of $7 million, a decrease in after-tax income from non-insurance businesses of $6 million, a decrease in after-tax service fee income of $8 million and an an increase in after-tax other expenses of $24 million. The number of weighted average diluted shares decreased as a result of the Company’s repurchases of its common stock in 2016 and 2015.
A summary of gross premiums written in 2016 compared with 2015 by line of business within each business segment follows:
Net premiums written were $6,424 million in 2016, an increase of 4% from $6,190 million in 2015. Ceded reinsurance premiums as a percentage of gross written premiums were 15% in both 2016 and 2015.
Premiums earned increased 4% to $6,293 million in 2016 from $6,041 million in 2015. Insurance premiums (including the impact of rate changes) are generally earned evenly over the policy term, and accordingly recent rate increases will be earned over the upcoming quarters. Premiums earned in 2016 are related to business written during both 2016 and 2015. Audit premiums were $156 million in 2016 compared with $153 million in 2015.
Net Investment Income. Following is a summary of net investment income for the years ended December 31, 2016 and 2015:
Insurance Service Fees. The Company earns fees from an insurance distribution business, a third party administrator, and as a servicing carrier of workers' compensation assigned risk plans for certain states. Insurance service fees were $139 million in 2016 and 2015.
Net Realized Gains on Investment Sales. The Company buys and sells securities on a regular basis in order to maximize its total return on investments. Decisions to sell securities are based on management’s view of the underlying fundamentals of specific securities as well as management’s expectations regarding interest rates, credit spreads, currency values and general economic conditions. Net realized gains on investment sales were $285 million in 2016 compared with $126 million in 2015. In 2016, realized gains were primarily related to the sale of Aero Precision Industries and the sale of some shares of a publicly traded common stock. In 2015, realized gains were primarily related to sale of some shares of a publicly traded common stock held by one of the Company's investment funds.
Revenues from Non-Insurance Businesses. Revenues from non-insurance businesses were derived from a business engaged in the distribution of promotional merchandise and aviation-related businesses that provide services to aviation markets, including (i) the distribution, manufacturing, repair and overhaul of aircraft parts and components, (ii) the sale of new and used aircraft, and (iii) avionics, fuel, maintenance, storage and charter services. Revenues from non-insurance businesses decreased to $390 million in 2016 from $421 million in 2015, primarily due to the sale of Aero Precision Industries in August 2016.
Insurance service expenses, which represent the costs associated with the fee-based businesses, increased 9% to $139 million.
Income Taxes. The effective income tax rate was 33% in 2016 compared to 31% in 2015. The higher tax rate in 2016 was due, in part, to higher capital gains and state taxes. The effective income tax rate differs from the federal income tax rate of 35% primarily because of tax-exempt investment income.
Supranational represents investments in the North American Development Bank, European Investment Bank and International Bank for Reconstruction & Development.
Equity Securities Available for Sale. Equity securities primarily represent investments in common and preferred stocks in companies with potential growth opportunities in different sectors, including healthcare and financial institutions.
Cash Flow. Cash flow provided from operating activities decreased to $711 million in 2017 from $848 million in 2016, primarily due to the timing of loss and loss expense payments and payments to taxing authorities.
Equity. The Company repurchased 731,003, 2,395,892 and 4,502,025 shares of its common stock in 2017, 2016 and 2015, respectively. The aggregate cost of the repurchases was $48 million in 2017, $132 million in 2016 and $224 million in 2015. At December 31, 2017, total common stockholders’ equity was $5.41 billion, common shares outstanding were 121,514,852 and stockholders’ equity per outstanding share was $44.53.
The Company files a consolidated income tax return in the U.S. and foreign tax returns in each of the countries in which it has overseas operations. At December 31, 2017, the Company had a gross deferred tax asset (net of valuation allowance) of $314 million (which primarily relates to loss and loss expense reserves and unearned premium reserves) and a gross deferred tax liability of $401 million (which primarily relates to deferred policy acquisition costs and unrealized investment gains). The realization of the deferred tax asset is dependent upon the Company's ability to generate sufficient taxable income in future periods. Based on historical results and the prospects for future operations, management anticipates that it is more likely than not that future taxable income will be sufficient for the realization of this asset.
As result of the mandatory repatriation provision of the Tax Cuts and Jobs Act of 2017, the Company recognized a tax on the undistributed earnings of its foreign subsidiaries. The Company plans to continue its policy to permanently reinvest the undistributed earnings of its foreign subsidiaries.
Casualty reinsurance treaties - The Company purchases casualty reinsurance to reduce its exposure to large individual casualty losses, workers’ compensation catastrophe losses and casualty losses involving multiple claimants or insureds for the majority of business written by its U.S. companies. A significant casualty treaty (casualty catastrophe) in effect as of January 1, 2018 provides protection for losses between $5 million and $75 million from single events with claims involving two or more insurable interests or for systemic events involving multiple insureds and/or policy years. The treaty also covers casualty contingency losses in excess of $1 million and up to $111 million. For losses involving two or more claimants for primary workers’ compensation business, coverage is generally in place for losses between $5 million and $220 million. For excess workers’ compensation business, such coverage is generally in place for losses between $25 million and $275 million.
Following is a summary of earned premiums and loss and loss expenses ceded to reinsurers for each of the three years ended December 31, 2017:
The following table presents the credit quality of amounts due from reinsurers as of December 31, 2017. Amounts due from reinsurers are net of reserves for uncollectible reinsurance of $1 million in the aggregate.
Following is a summary of the Company's contractual obligations as of December 31, 2017:
We have audited the accompanying consolidated balance sheets of W. R. Berkley Corporation and Subsidiaries (the “Company”) as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes and financial statement schedules II to VI (collectively, the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 23, 2018 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
The consolidated financial statements, which include the accounts of W. R. Berkley Corporation and its subsidiaries (the "Company"), have been prepared on the basis of U.S. generally accepted accounting principles ("GAAP"). All significant intercompany transactions and balances have been eliminated. Reclassifications have been made in the 2016 and 2015 financial statements to conform to the presentation of the 2017 financial statements. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the revenues and expenses reflected during the reporting period. The most significant items on our balance sheet that involve a greater degree of accounting estimates that are subject to change in the future are the valuation of investments, other-than-temporary impairments, loss and loss expense reserves and premium estimates. Actual results could differ from those estimates.
Revenues from non-insurance businesses are derived from a business engaged in the distribution of promotional merchandise, world-wide textile solutions, and aircraft services provided to the general, commercial and military aviation markets. These aircraft services include (i) the distribution, manufacturing, repair and overhaul of aircraft parts and components, (ii) the sale of new and used aircraft, and (iii) avionics, fuel, maintenance, storage and charter services. Revenue is recognized upon the shipment of products and parts, the delivery of aircraft, the delivery of fuel, and upon completion of services.
of the building. Minimum rental income is recognized on a straight-line basis over the lease term. Income and expenses from real estate are reported as net investment income. The carrying value of real estate is reviewed for impairment and an impairment loss is recognized if the estimated undiscounted cash flows from the use and disposition of the property are less than the carrying value of the property.
The Company presents both basic and diluted net income per share (“EPS”) amounts. Basic EPS is calculated by dividing net income by weighted average number of common shares outstanding during the year (including 4,847,303 common shares held in a grantor trust established in March 2017). The common shares held in the grantor trust are for delivery upon settlement of vested but mandatorily deferred restricted stock units ("RSUs"). Shares held by the grantor trust do not affect diluted shares outstanding since the shares deliverable under vested RSUs were already included in diluted shares outstanding. Diluted EPS is based upon the weighted average number of basic and common equivalent shares outstanding during the year and is calculated using the treasury stock method for stock incentive plans. Common equivalent shares are excluded from the computation in periods in which they have an anti-dilutive effect.
Contracts that do not meet the risk transfer requirements of GAAP are accounted for using the deposit accounting method. Under this method, an asset or liability is recognized at the inception of the contract based on consideration paid or received. The amount of the deposit asset or liability is adjusted at subsequent reporting dates using the interest method with a corresponding credit or charge to interest income or expense. Deposit liabilities for assumed reinsurance contracts were $47 million and $51 million at December 31, 2017 and 2016, respectively.
Property, furniture and equipment are carried at cost less accumulated depreciation. Depreciation is calculated using the estimated useful lives of the respective assets. Depreciation expense was $50 million, $47 million and $45 million for 2017, 2016 and 2015, respectively.
Goodwill and other intangible assets are tested for impairment on an annual basis and at interim periods where circumstances require. The Company's impairment test as of December 31, 2017 indicated that there were no material impairment losses related to goodwill and other intangible assets. Intangible assets of $107 million and $82 million are included in other assets as of December 31, 2017 and 2016, respectively.
In May 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2015-09, Disclosures about Short-Duration Contracts. ASU 2015-09 requires companies that issue short duration insurance contracts to disclose additional information, including: (i) incurred and paid claims development tables; (ii) frequency and severity of claims; and (iii) information about material changes in judgments made in calculating the liability for unpaid claim adjustment expenses, including reasons for the change and the effects on the financial statements. The Company adopted this updated guidance on January 1, 2016 with regard to the annual requirements and on January 1, 2017 with regard to the interim requirements. The amendments in ASU 2015-09 are applied retrospectively by providing comparative disclosures for each period presented, except for those requirements that apply only to the current period. As the requirements are disclosure only, the adoption of this guidance did not impact our financial condition or results of operations, but did result in additional disclosures.
based payment awards for tax purposes that exceed the compensation cost recognized for financial reporting purposes) are reported within the income tax expense financial statement line item. Previously, excess tax benefits were reported within additional paid in capital. The Company adopted this updated guidance on January 1, 2017 prospectively. The adoption of this guidance did not have a material impact on the Company's financial condition or results of operations.
All other accounting and reporting standards that became effective in 2017 were either not applicable to the Company or their adoption did not have a material impact on the Company.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments. ASU 2016-01 amends the accounting guidance for financial instruments to require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The updated guidance is effective for public business entities for annual reporting periods beginning after December 15, 2017 and interim periods within those years. The adoption of this guidance is not expected to have a material effect on the Company’s financial condition upon adoption, but will impact results of operations after adoption of this guidance as unrealized gains and losses on equity securities will no longer be reported directly in accumulated other comprehensive income (AOCI), but will instead be reported in net income.
In March 2017, the Company acquired an 89.5% ownership interest for $73.3 million in a company engaged in providing textile solutions world-wide. The fair value of the assets acquired and liabilities assumed have been estimated based on a third party valuation.
The following table summarizes the estimated fair value of net assets acquired and liabilities assumed for the business combination completed in 2017:
In February 2016, the Company acquired an 85% ownership interest for $42.3 million in a company engaged in the distribution of promotional merchandise.
The following tables present the components of the changes in accumulated other comprehensive income (loss) (AOCI) as of and for the years ended December 31, 2017 and 2016:
The amortized cost and fair value of fixed maturity securities at December 31, 2017, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities because certain issuers may have the right to call or prepay obligations.
At December 31, 2017 and 2016, there were no investments, other than investments in United States government and government agency securities, which exceeded 10% of common stockholders’ equity. At December 31, 2017, investments with a carrying value of $1,353 million were on deposit in custodial or trust accounts, of which $995 million was on deposit with state insurance departments, $308 million was on deposit in support of the Company’s underwriting activities at Lloyd’s, $46 million was on deposit as security for reinsurance clients and $4 million was on deposit as security for letters of credit issued in support of the Company’s reinsurance operations.
At December 31, 2017 and 2016, investments in equity securities available for sale were as follows:
At December 31, 2017 and 2016, the fair value and carrying value of the arbitrage trading account were $618 million and $300 million, respectively. The primary focus of the trading account is merger arbitrage. Merger arbitrage is the business of investing in the securities of publicly held companies which are the targets in announced tender offers and mergers. Arbitrage investing differs from other types of investing in its focus on transactions and events believed likely to bring about a change in value over a relatively short time period (usually four months or less).
The Company evaluates whether it is an investor in a variable interest entity (VIE). Such entities do not have sufficient equity at risk to finance their activities without additional subordinated financial support, or the equity investors, as a group, do not have the characteristics of a controlling financial interest (primary beneficiary). The Company determines whether it is the primary beneficiary of an entity subject to consolidation based on a qualitative assessment of the VIE's capital structure, contractual terms, nature of the VIE's operations and purpose, and the Company's relative exposure to the related risks of the VIE on the date it becomes initially involved in the VIE and on an ongoing basis. The Company is not the primary beneficiary in any of its investment funds, and accordingly, carries its interests in investments funds under the equity method of accounting.
The Company’s maximum exposure to loss with respect to these investments is limited to the carrying amount reported on the Company’s consolidated balance sheet and its unfunded commitments of $406.2 million as of December 31, 2017.
Loans receivable in non-accrual status were $4.3 million and $5.4 million as of December 31, 2017 and 2016, respectively.
(1) Investment funds includes a gain of $124.3 million from the sale of an investment in an office building located in Washington, D.C. for the year ended December 31, 2017.
(2) Other includes a gain of $134.9 million from the sale of Aero Precision Industries and certain related aviation services business for the year ended December 31, 2016.
(3) There were no other than temporary impairments (OTTI) for the year ended December 31, 2017. For the year ended December 31, 2016, OTTI related to equity securities was $18.1 million. For the year ended December 31, 2015, OTTI related to equity securities was $24.3 million and related to fixed maturity securities was $9.0 million.
For the years ended December 31, 2017 and 2016, there were no OTTI recognized in earnings for fixed maturity securities.
Preferred Stocks - At December 31, 2017, there was one preferred stock in an unrealized loss position, with an aggregate fair value of $23.1 million and a gross unrealized loss of $2.6 million. The preferred stock is rated investment grade. Management believes the unrealized loss is due primarily to market and sector related factors and does not consider it to be OTTI. For the year ended December 31, 2017 and 2016, there were no OTTI for preferred stocks.
The following is supplementary information regarding average historical claims duration as of December 31, 2017:
The decrease in estimates for claims occurring in prior years is net of loss reserve discount. On an undiscounted basis, the estimates for claims occurring in prior years decreased by $32,132,000, $59,175,000 and $64,971,000 in 2017, 2016 and 2015, respectively.
For workers' compensation, the favorable development was related to both primary and excess business and to many accident years, including those prior to 2007. During 2016, reported workers' compensation losses continued to be below our expectations at most of our operating units. Loss frequency and severity trends continued to be better than the assumptions underlying our previous reserve estimates. Loss severity trends also benefited from our continued investment in medical case management services and from our preferred provider networks. The long term trend of declining workers' compensation frequency can be attributed to improved workplace safety.
Reinsurance - Reserves for the Reinsurance segment developed favorably by 6 million in 2016. The favorable development was primarily related to direct facultative reinsurance business and to accident years 2008 through 2014.
For professional indemnity business in the U.K., adverse development was primarily for accident years 2006 through 2013.
Reinsurance - Reserves for the Reinsurance segment developed favorably by $11 million in 2015. The favorable development was primarily related to direct facultative reinsurance business and to accident years 2005 through 2013. Loss reserves developed favorably for umbrella business and for other liability coverage for contractors.
Discounting - The Company discounts its liabilities for certain workers’ compensation reserves. The amount of workers’ compensation reserves that were discounted was $1,855 million and $1,907 million at December 31, 2017 and December 31, 2016, respectively. The aggregate net discount for those reserves, after reflecting the effects of ceded reinsurance, was $591 million and $640 million at December 31, 2017 and 2016, respectively. At December 31, 2017, discount rates by year ranged from 2.0% to 6.5%, with a weighted average discount rate of 3.8%.
The Company has calculated the effects of the Tax Act as of December 31, 2017 and has included in its financial statements provisional estimates of its impact. The Company anticipates further guidance will be forthcoming and will continue to review and refine its calculations as guidance is provided and additional analysis of the Company's information is completed.
As noted above, as a result of the mandatory repatriation provision of the Tax Act, the Company recognized a tax on the undistributed earnings of its foreign subsidiaries. The Company intends to continue its policy to permanently reinvest the undistributed earnings of its foreign subsidiaries.
The significant variances between SAP and GAAP are that for statutory purposes bonds are carried at amortized cost, acquisition costs are charged to income as incurred, deferred Federal income taxes are subject to limitations, excess and assumed workers’ compensation reserves are discounted at different discount rates and certain assets designated as “non-admitted assets” are charged against surplus. The Commissioner of Insurance of the State of Delaware has allowed BIC to discount non-tabular workers' compensation loss reserves, which is a permitted practice that differs from SAP. The effect of using this permitted practice was an increase to BIC’s statutory capital and surplus by $277 million at December 31, 2017.
The National Association of Insurance Commissioners (“NAIC”) has risk-based capital (“RBC”) requirements that require insurance companies to calculate and report information under a risk-based formula which measures statutory capital and surplus needs based on a regulatory definition of risk in a company’s mix of products and its balance sheet. This guidance is used to calculate two capital measurements: Total Adjusted Capital and RBC Authorized Control Level. Total Adjusted Capital is equal to the Company’s statutory capital and surplus excluding capital and surplus derived from the use of permitted practices that differ from statutory accounting practices. RBC Authorized Control Level is the capital level used by regulatory authorities to determine whether remedial action is required. Generally, no remedial action is required if Total Adjusted Capital is 200% or more of the RBC Authorized Control Level. At December 31, 2017, BIC’s Total Adjusted Capital of $5.203 billion was 397% of its RBC Authorized Control Level.
Treasury shares have been excluded from average outstanding shares from the date of acquisition. The weighted average number of basic shares outstanding includes the impact of 4,847,303 common shares held in a grantor trust established in March 2017. The common shares held in the grantor trust are for delivery upon settlement of vested but mandatorily deferred restricted stock units ("RSUs"). Shares held by the grantor trust do not affect diluted shares outstanding since shares deliverable under vested RSUs were already included in diluted shares outstanding. The difference in calculating basic and diluted net income per share is attributable entirely to the dilutive effect of stock-based compensation plans. Changes in shares of common stock outstanding, net of treasury shares, are presented below. Shares of common stock issued and outstanding do not include shares related to unissued restricted stock units (including shares held in the grantor trust).
The estimated fair values of the Company’s fixed maturity securities, equity securities available for sale and arbitrage trading account securities are based on various valuation techniques that rely on fair value measurements as described in Note 13 above. The fair value of loans receivable is estimated by using current institutional purchaser yield requirements for loans with similar credit characteristics, which is considered a Level 2 input. The fair value of the senior notes and other debt and the subordinated debentures is based on spreads for similar securities, which is considered a Level 2 input.

The Company and its subsidiaries have profit sharing plans in which substantially all employees participate. The plans provide for minimum annual contributions of 5% of eligible compensation; contributions above the minimum are discretionary and vary with each participating subsidiary’s profitability. Employees become eligible to participate in the plan on the first day of the calendar quarter following the first full calendar quarter after the employee's date of hire provided the employee has completed 250 hours of service during the calendar quarter. The plans provide that 40% of the contributions vest immediately and that the remaining 60% vest at varying percentages based upon years of service. Profit sharing expense was $42 million, $39 million and $42 million in 2017, 2016 and 2015, respectively.
