Lord Abbett Series Fund — Bond Debenture Portfolio
Annual Report

For the fiscal year ended December 31, 2016

From left to right: James L.L. Tullis, Chairman of the Lord Abbett Funds and Daria L. Foster Director, President, and Chief Executive Officer of the Lord Abbett Funds. Dear Shareholders: We are pleased to provide you with this overview of the performance of Lord Abbett Series Fund — Bond Debenture Portfolio for the fiscal year ended December 31, 2016. On this page, and the following pages, we discuss the major factors that influenced fiscal year performance. For additional information about the Fund, please visit our website at www.lordabbett.com, where you also can access the quarterly commentaries that provide updates on the Fund’s performance and other portfolio related updates. Thank you for investing in Lord Abbett mutual funds. We value the trust that you place in us and look forward to serving your investment needs in the years to come.   Best regards,   Daria L. Foster Director, President and Chief Executive Officer

For the fiscal year ended December 31, 2016, the Fund returned 12.13%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the Bloomberg Barclays U.S. Aggregate Bond Index¹ which returned 2.65% over the same period.

The high yield sector of the U.S. fixed income market experienced strong returns during the 12-month period, outperforming traditional government-related and investment grade securities

within the fixed income market as well as the U.S. equity market. Leveraged loans also experienced strong returns, although not to the same extent as high yield bonds.

As it has in the past, the Fund maintained a significant allocation to high yield bonds, as we remained positive on the high yield market from a fundamental perspective. The Fund’s exposure to high yield bonds likely contributed to relative performance, as the high yield market significantly outperformed the Fund’s benchmark.

1

The Fund maintained a sizable allocation to equities throughout the period, as equities provided portfolio diversification, a high degree of liquidity, and a more diverse opportunity set to express certain investment themes than did certain fixed income securities. The Fund’s allocation to equities likely contributed to relative performance, as the asset class outperformed the Bloomberg Barclays U.S. Aggregate Bond Index.

Within the Fund’s investment grade bond allocation, the Fund’s exposure to ‘AAA’ rated bonds likely detracted from performance, as ‘AAA’ rated bonds underperformed the benchmark during the period.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹   The Bloomberg Barclays U.S. Aggregate Bond Index represents securities that are SEC-registered, taxable, and dollar-denominated. The index covers the U.S. investment-grade fixed-rate bond market, with index components for government and corporate securities, mortgage pass-through securities, and asset-backed securities. Total return comprises price appreciation/depreciation and income as a percentage of the original investment.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense

waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer own the securities described above or may have otherwise changed their positions in the securities. For more recent information about the Fund’s portfolio holdings, please visit www.lordabbett.com.

A Note about Risk: See Notes to Financial Statements for a discussion of investment risks. For a more detailed discussion of the risks associated with each Fund, please see the Fund’s prospectus.

Mutual funds are not insured by the FDIC, are not deposits or other obligations of, or guaranteed by, banks, and are subject to investment risks including possible loss of principal amount invested.

The Fund serves as an underlying investment vehicle for variable annuity contracts and variable life insurance policies.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the Bloomberg Barclays U.S. Aggregate Bond Index and the BofA Merrill Lynch U.S. High Yield Constrained Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. This line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During certain periods, expenses of the Fund have been waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

	Average Annual Total Returns for the Periods Ended December 31, 2016
		1 Year		5 Years		10 Years
Class VC		12.13	%	7.00	%	6.82	%

¹   Performance for each unmanaged index does not reflect any fees or expenses. The performance of each index is not necessarily representative of the Fund’s performance.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

4

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning	Ending	Expenses
	Account	Account	Paid During
	Value	Value	Period†
			7/1/16 -
	7/1/16	12/31/16	12/31/16

Hypothetical (5% Return Before Expenses)	$1,000.00	$1,020.61	$4.57

^† Net expenses are equal to the Fund’s annualized expense ratio of 0.90%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

(1)	Refer to Note 2(n) for a description of fair value measurements and the three-tier hierarchy of inputs.
(2)	See Schedule of Investments for fair values in each industry and identification of foreign issuers and/or geography. The table above is presented by Investment Type. Industries are presented within an Investment Type should such Investment Type include securities classified as two or more levels within the three-tier fair value hierarchy.
(3)	Includes securities valued using third party pricing information without adjustment. Such valuations are based on unobservable inputs. A significant change in third party information could result in a significantly lower or higher value of such Level 3 investments.
(4)	Level 3 securities fair valued by the Pricing Committee, as described in Note 2(a) in the Notes to Financials.
(5)	As of December 31, 2016, Moncler SpA. was categorized as level 1 due to an active market quoted price. For the period ended December 31, 2016, the total amount transferred from Level 2 to Level 1 was $899,705.
(6)	Floating Rate Loans categorized as Level 3 are valued based on a single quotation obtained from a dealer. Accounting principles generally accepted in the United States of America do not require the Fund to create quantitative unobservable inputs that were not developed by the Fund. Therefore, the Fund does not have access to unobservable inputs and cannot disclose such inputs in the valuation.

The Company consists of thirteen separate portfolios. This report covers Bond-Debenture Portfolio (the “Fund”).

The Fund’s investment objective is to seek high current income and the opportunity for capital appreciation to produce a high total return. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES 

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices. Fixed income securities are valued based on evaluated prices supplied by independent pricing services, which reflect broker/dealer supplied valuations and the independent pricing services’ own electronic data processing techniques. Exchange traded options and futures contracts are valued at the last sale price in the market where they are principally traded. If no sale has occurred, the mean between the most recently quoted bid and asked prices is used. Floating rate loans are valued at the average of bid and ask quotations obtained from dealers in loans on the basis of prices supplied by independent pricing services. Forward foreign currency exchange contracts are valued using daily forward exchange rates. Swaps are valued daily using independent pricing services or quotations from broker/dealers to the extent available.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including

48

Notes to Financial Statements (continued)

	observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values, yield curves, broker quotes, observable trading activity, option adjusted spread models and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.
(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on futures contracts, swaps and translation of assets and liabilities denominated in foreign currencies on the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized loss on futures contracts, swaps and foreign currency related transactions on the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
	The Fund uses foreign currency exchange contracts to facilitate transactions in foreign-denominated securities. Losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts’ terms.

49

Notes to Financial Statements (continued)

(g)	Forward Foreign Currency Exchange Contracts–The Fund may enter into forward foreign currency exchange contracts in order to reduce exposure to changes in foreign currency exchange rates on foreign portfolio holdings, or gain or reduce exposure to foreign currency solely for investment purposes. A forward foreign currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated rate. The contracts are valued daily at forward exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on futures contracts, swaps and translation of assets and liabilities denominated in foreign currencies on the Fund’s Statement of Operations. The gain (loss) arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing of such contracts is included in Net realized loss on futures contracts, swaps and foreign currency related transactions on the Fund’s Statement of Operations.
(h)	Futures Contracts–The Fund may purchase and sell futures contracts to enhance returns, to attempt to economically hedge some of its investment risk, or as a substitute position in lieu of holding the underlying asset on which the instrument is based. At the time of entering into a futures transaction, an investor is required to deposit and maintain a specified amount of cash or eligible securities called “initial margin.” Subsequent payments made or received by the Fund called “variation margin” are made on a daily basis as the market price of the futures contract fluctuates. The Fund will record an unrealized gain (loss) based on the amount of variation margin. When a contract is closed, a realized gain (loss) is recorded equal to the difference between the opening and closing value of the contract.
(i)	When-Issued, Forward Transactions or To-Be-Announced (“TBA”) Transactions–The Fund may purchase portfolio securities on a when-issued or forward basis. When-issued, forward transactions or TBA transactions involve a commitment by a fund to purchase securities, with payment and delivery (“settlement”) to take place in the future, in order to secure what is considered to be an advantageous price or yield at the time of entering into the transaction. During the period between purchase and settlement, the fair value of the securities will fluctuate and assets consisting of cash and/or marketable securities (normally short-term U.S. Government or U.S. Government sponsored enterprise securities) marked to market daily in an amount sufficient to make payment at settlement will be segregated at the Fund’s custodian in order to pay for the commitment. At the time the Fund makes the commitment to purchase a security on a when-issued basis, it will record the transaction and reflect the liability for the purchase and fair value of the security in determining its net asset value (“NAV”). The Fund, generally, has the ability to close out a purchase obligation on or before the settlement date rather than take delivery of the security. Under no circumstances will settlement for such securities take place more than 120 days after the purchase date.
(j)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.

50

Notes to Financial Statements (continued)

(k)	Reverse Repurchase Agreements–Each Fund may enter into reverse repurchase agreements. In a reverse repurchase agreement, a Fund sells a security to a securities dealer or bank for cash and also agrees to repurchase the same security later at a set price. Reverse repurchase agreements expose the Fund to credit risk (that is, the risk that the counterparty will fail to resell the security to the Fund). Engaging in reverse repurchase agreements also may involve the use of leverage, in that the Fund may reinvest the cash it receives in additional securities. Reverse repurchase agreements involve the risk that the market value of the securities to be repurchased by the Fund may decline below the repurchase price.
(l)	Credit Default Swaps–The Fund may enter into credit default swap contracts in order to hedge credit risk or for speculation purposes. As a seller of a credit default swap contract (“seller of protection”), the Fund is required to pay the notional amount or other agreed-upon value of a referenced debt obligation to the counterparty in the event of a default by or other credit event involving the referenced issuer, obligation or index. In return, the Fund receives from the counterparty a periodic stream of payments over the term of the contract.
	As a purchaser of a credit default swap contract (“buyer of protection”), the Fund would receive the notional amount or other agreed upon value of a referenced debt obligation from the counterparty in the event of default by or other credit event involving the referenced issuer, obligation or index. In return, the Fund would make periodic payments to the counterparty over the term of the contracts, provided no event of default has occurred.
	These credit default swaps may have as a reference obligation corporate or sovereign issuers or credit indices. These credit indices are comprised of a basket of securities representing a particular sector of the market.
	Credit default swaps are fair valued based upon quotations from counterparties, brokers or market-makers and the change in value, if any, is recorded as an unrealized appreciation or depreciation. For a credit default swap sold by the Fund, payment of the agreed-upon amount made by the Fund in the event of default of the referenced debt obligation is recorded as the cost of the referenced debt obligation purchased/received. For a credit default swap purchased by the Fund, the agreed-upon amount received by the Fund in the event of default of the referenced debt obligation is recorded as proceeds from sale/delivery of the referenced debt obligation and the resulting gain or loss realized on the referenced debt obligation is recorded as such by the Fund.
	Any upfront payments made or received upon entering a credit default swap contract would be amortized or accreted over the life of the swap and recorded as realized gains or losses. Collateral, in the form of cash or securities, may be required to be held in segregated accounts with the custodian bank or broker in accordance with the swap agreement. The value and credit rating of each credit default swap where the Fund is the seller of protection, are both measures of the current payment/performance risk of the swap. As the value of the swap changes as a positive or negative percentage of the total notional amount, the payment/performance risk may decrease or increase, respectively. The maximum potential amount of future payments (undiscounted) that the Fund as a seller of protection could be required to make under a credit default swap agreement would be an amount equal to the notional amount of the agreement. These potential amounts would be partially offset by any recovery values of the respective referenced obligations, upfront payments received upon entering into the agreement, or net amounts received from the settlement of buy protection credit default swap agreements entered into by the Fund for the same referenced entity or entities.

51

Notes to Financial Statements (continued)

	Entering into credit default swaps involves credit and market risk. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates, and that Lord Abbett does not correctly predict the creditworthiness of the issuers of the reference obligation on which the credit default swap is based.
(m)	Floating Rate Loans–The Fund may invest in floating rate loans, which usually take the form of loan participations and assignments. Loan participations and assignments are agreements to make money available to U.S. or foreign corporations, partnerships or other business entities (the “Borrower”) in a specified amount, at a specified rate and within a specified time. A loan is typically originated, negotiated and structured by a U.S. or foreign bank, insurance company or other financial institution (the “Agent”) for a group of loan investors (“Loan Investors”). The Agent typically administers and enforces the loan on behalf of the other Loan Investors in the syndicate and may hold any collateral on behalf of the Loan Investors. Such loan participations and assignments are typically senior, secured and collateralized in nature. The Fund records an investment when the Borrower withdraws money and records interest as earned. These loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or London InterBank Offered Rate (“LIBOR”).
	The loans in which the Fund invests may be subject to some restrictions on resale. For example, the Fund may be contractually obligated to receive approval from the Agent and/or Borrower prior to the sale of these investments. The Fund generally has no right to enforce compliance with the terms of the loan agreement with the Borrower. As a result, the Fund assumes the credit risk of the Borrower, the selling participant and any other persons interpositioned between the Fund and the Borrower (“Intermediate Participants”). In the event that the Borrower, selling participant or Intermediate Participants become insolvent or enter into bankruptcy, the Fund may incur certain costs and delays in realizing payment or may suffer a loss of principal and/or interest.
	Unfunded commitments represent the remaining obligation of the Fund to the Borrower. At any point in time, up to the maturity date of the issue, the Borrower may demand the unfunded portion. Until demanded by the Borrower, unfunded commitments are not recognized as an asset on the Statement of Assets and Liabilities. Unrealized appreciation/depreciation on unfunded commitments presented on the Statement of Assets and Liabilities represents mark to market of the unfunded portion of the Fund’s floating rate notes. As of December 31, 2016, the Fund had no unfunded loan commitment.
(n)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk – for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or

52

Notes to Financial Statements (continued)

liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:
•	Level 1 –	unadjusted quoted prices in active markets for identical investments;
•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).
A summary of inputs used in valuing the Fund’s investments and other financial instruments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.
Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES 

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.50%
Over $1 billion	.45%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of .47% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses to an annual rate of .90%. This agreement may be terminated only upon the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily NAV of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The

53

Notes to Financial Statements (continued)

Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS 

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended		Year Ended
	12/31/2016		12/31/2015
Distributions paid from:
Ordinary income	$	47,075,516	$	41,858,433
Net long-term capital gains		–		5,541,865
Total distributions paid	$	47,075,516	$	47,400,298

As of December 31, 2016, the components of accumulated gains on a tax-basis were as follows:

Capital loss carryforwards*	$	(22,106,945	)
Temporary differences		(133,147	)
Unrealized gains – net		41,021,871
Total accumulated gains – net	$	18,781,779

* The capital losses will carryforward indefinitely

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	1,012,297,828
Gross unrealized gain		54,164,307
Gross unrealized loss		(12,722,196	)
Net unrealized security gain	$	41,442,111

54

Notes to Financial Statements (continued)

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to the tax treatment of certain distributions received, premium amortization and wash sales.

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Distributions in
Excess of Net
Investment	Accumulated Net
Income	Realized Loss	Paid-in Capital
$1,980,492	$(1,844,812)	$(135,680)

The permanent differences are attributable to the tax treatment of premium amortization, certain securities, certain distributions and foreign currency transactions.

5. PORTFOLIO SECURITIES TRANSACTIONS 

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

U.S.	Non-U.S.	U.S.	Non-U.S.
Government	Government	Government	Government
Purchases*	Purchases	Sales*	Sales
$197,236,658	$1,036,374,302	$212,132,059	$984,859,960

* Includes U.S. Government sponsored enterprise securities.

The Fund is permitted to purchase and sell securities (“cross-trade”) from and to other Lord Abbett funds or client accounts pursuant to procedures approved by the Board in compliance with Rule 17a-7 under the Act (the “Rule”). Each cross-trade is executed at a fair market price in compliance with provisions of the Rule. For the period ended December 31, 2016, the Fund engaged in crosstrades purchases of $551,529 and sales of $8,951,649, which resulted in net realized loss of $(166,490).

6. DISCLOSURES ABOUT DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES 

The Fund entered into forward foreign currency exchange contracts for the fiscal year ended December 31, 2016 (as described in note 2(g)). A forward foreign currency exchange contract reduces the Fund’s exposure to changes in the value of the currency it will deliver (or settle in cash) and increases its exposure to changes in the value of the currency it will receive (or settle in cash) for the duration of the contract. The Fund’s use of forward foreign currency exchange contracts involves the risk that Lord Abbett will not accurately predict currency movements, and the Fund’s returns could be reduced as a result. Forward foreign currency exchange contracts are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time. The Fund’s risk of loss from counterparty credit risk is the unrealized appreciation on forward foreign currency exchange contracts and deposits with brokers as collateral.

The Fund entered into U.S. Treasury futures contracts for the fiscal year ended December 31, 2016 (as described in note 2(h)) to economically hedge against changes in interest rates. The Fund bears the risk of interest rates moving unexpectedly, in which case the Fund may not achieve the anticipated benefits of the futures contracts and realize a loss. There is minimal counterparty credit risk to the Fund since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees futures against default.

55

Notes to Financial Statements (continued)

The Fund entered into centrally cleared credit default swaps on indexes during the fiscal year ended December 31, 2016 (as described in note 2(l)) to economically hedge credit risk. Centrally cleared credit default swaps on indexes involve the exchange of a fixed rate premium for protection against the loss in value of underlying securities within an index in the event of a defined credit event, such as payment default or bankruptcy. Under a credit default swap one party acts as a guarantor by receiving the fixed periodic payment in exchange for the commitment to purchase the underlying security at par if the defined credit event occurs. Upon the occurrence of a defined credit event, the difference between the value of the reference obligation and the swap’s notional amount is recorded as realized gain or loss on swap transactions in the Statements of Operations. There is minimal counterparty credit risk to the Funds since these credit default swaps are traded through a central clearinghouse. As a counterparty to all centrally cleared credit default swaps, the clearinghouse guarantees credit default swaps against default.

As of December 31, 2016, the Fund had the following derivatives at fair value, grouped into appropriate risk categories that illustrate the Fund’s use of derivative instruments:

		Foreign
	Interest Rate	Currency	Credit
Asset Derivatives	Contracts	Contracts	Contracts

7. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES 

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

8. DIRECTORS’ REMUNERATION 

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

9. EXPENSE REDUCTIONS 

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

10. LINE OF CREDIT 

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

11. INTERFUND LENDING PROGRAM 

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund participated as a lender in the Interfund Lending Program. The average amount loaned and interest rate were $12,712,216 and 0.725%, respectively. The Fund earned interest of $253, which is included in the Statement of Operations. There were no interfund loans outstanding as of December 31, 2016.

12. CUSTODIAN AND ACCOUNTING AGENT 

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

13. INVESTMENT RISKS 

The Fund is subject to the general risks and considerations associated with investing in debt securities. The value of an investment will change as interest rates fluctuate and in response to market movements. When interest rates rise, the prices of debt securities are likely to decline; when rates fall, such prices tend to rise. Longer-term debt securities are usually more sensitive to interest rate changes. There is also the risk that an issuer of a debt security will fail to make timely payments of principal or interest to the Fund, a risk that is greater with high-yield securities (sometimes called “lower-rated bonds” or “junk bonds”) in which the Fund may substantially invest. Some issuers, particularly of high-yield securities, may default as to principal and/or interest payments after the Fund purchases its securities. A default, or concerns in the market about an increase in risk of default, may result in losses to the Fund. High-yield securities are subject to greater price fluctuations, as well as additional risks.

The mortgage-related securities in which the Fund may invest may be particularly sensitive to changes in prevailing interest rates and economic conditions, including delinquencies and/or defaults. These changes can affect the value, income and/or liquidity of such positions. When interest rates are declining, the value of these securities with prepayment features may not increase as much as other fixed income securities. Early principal repayment may deprive the Fund of income payments above current market rates. Alternatively, rising interest rates may cause

59

Notes to Financial Statements (concluded)

prepayments to occur at a slower-than-expected rate, extending the duration of a security and typically reducing its value. The payment rate will thus affect the price and volatility of a mortgage-related security. In addition, while securities of government sponsored enterprises are guaranteed with respect to the timely payment of interest and principal by the particular enterprise involved, they are not guaranteed by the U.S. Government. In addition, the Fund may invest in non-agency asset backed and mortgage-related securities, which are issued by private institutions, not by government sponsored enterprises.

The Fund may invest a portion of its net assets in equity securities, the value of which fluctuates in response to movements in the equity securities market in general and to the changing prospects of individual companies in which the Fund invests.

The Fund may invest in convertible securities, which have both equity and fixed income risk characteristics. Generally, convertible securities offer lower interest or dividend yields than non-convertible securities of similar quality and less potential for gains or capital appreciation in a rising equity securities market than equity securities. They tend to be more volatile than other fixed income securities, and the market for convertible securities may be less liquid than the markets for stocks or bonds. A significant portion of convertible securities have below investment grade credit ratings and are subject to increased credit and liquidity risks.

Due to the Fund’s investment exposure to foreign companies and American Depositary Receipts, the Fund may experience increased market, liquidity, currency, political, information and other risks.

The Fund is subject to the risks associated with derivatives, which may be different from and greater than the risks associated with directly investing in securities. Derivatives may be subject to risks such as liquidity risk, leveraging risk, interest rate risk, market risk, and credit risk. Illiquid securities may lower the Fund’s returns since the Fund may be unable to sell these securities at their desired time or price. Derivatives also may involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the value of the underlying asset, rate or index. Whether the Fund’s use of derivatives is successful will depend on, among other things, the Fund’s ability to correctly forecast market movements and other factors. If the Fund incorrectly forecasts these and other factors, the Fund’s performance could suffer. The Fund’s use of derivatives could result in a loss exceeding the amount of the Fund’s investment in these instruments.

The Fund may invest a portion of its net assets in floating rate or adjustable rate senior loans, including bridge loans, novations, assignments, and participations, which are subject to increased credit and liquidity risks. Senior loans are business loans made to borrowers that may be U.S. or foreign corporations, partnerships or other business entities.

These factors can affect the Fund’s performance.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Bond-Debenture Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Bond-Debenture Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian, brokers, and agent banks; when replies were not received from brokers and agent banks, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Bond-Debenture Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year, three-year, five-year and ten-year periods. The Board also considered Lord Abbett’s performance and reputation generally, the

67

Approval of Advisory Contract (continued)

performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoint in the level of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible

68

Approval of Advisory Contract (concluded)

benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

For the fiscal year ended December 31, 2016, the Fund returned 15.10%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the S&P 500^® Index¹, which returned 11.96% over the same period.

Domestic equity markets (as represented by the S&P 500^® Index¹) returned 11.96% over the past year. Despite this general move higher, there were significant bouts of volatility within U.S. stock markets, including their worst start to a calendar year on record.

Crude oil prices played a significant role in the increased market volatility, as Brent oil prices fluctuated sharply throughout the fiscal year. In December, the Organization of Petroleum Exporting Countries agreed to reduce oil production effective 2017. Furthermore, global markets were affected by the devaluation of China’s currency and weak economic data out of the region. The Chinese economy advanced at an annual rate of 6.7% in the third quarter of 2016, a slower pace than in recent years.

1

Geopolitical events also contributed to volatility in global markets. The United Kingdom’s referendum in June to leave the European Union (“Brexit”) was a surprise that caused a sell-off in global markets.

In contrast to the equity market volatility, the U.S. economy continued to expand during the trailing 12-month period. The Federal Reserve (Fed) raised target rates for the second time in 12 months in December, from 0.25%–0.50% to 0.50%–0.75%. U.S. gross domestic product (GDP) grew at a 3.2% pace during the third quarter, a significant increase over the second quarter. The U.S. Bureau of Economic Analysis stated that during the third-quarter personal consumption and federal government spending increased. In addition to GDP growth, the U.S. unemployment rate remained relatively steady throughout the period, finishing at 4.6% in November.

The U.S. presidential election took an unexpected turn as Donald J. Trump was elected president, in contrast to indications from poll numbers before the election. Markets rallied on improved clarity in the U.S. political agenda, with the House and Senate also under Republican control.

The Fund focuses on U.S. large cap companies that consistently have grown their dividends over time, which represents a relatively narrow market segment, compared to its benchmark, the S&P 500. Relative to the S&P 500 benchmark, stock selection and sector weightings drove the Fund’s relative performance during the year.

Stock selection in the industrials sector was a positive contributor to the Fund’s performance, relative to its benchmark, during the period. Within industrials, one of the largest contributors was 3M Co., a diversified industrial manufacturer. 3M Co. reported stable, positive growth throughout the year with additional growth being forecasted in the future. Also contributing to relative performance was FedEx Corp., a provider of transportation, e-commerce, and business services. FedEx reported a strong fiscal first quarter of 2017, which beat consensus estimates, with earnings per share growing 20% year over year. In addition, the company was able to raise ground daily package volumes by 10%, while increasing margins in the segment by 0.20%.

The Fund’s sector underweight and positive stock selection in the health care sector also contributed to the Fund’s performance, relative to its benchmark. Within the health care sector, an overweight position in C.R. Bard, Inc., a medical equipment manufacturer, helped relative performance. The company benefited from a strong second quarter earnings report, which beat consensus estimates and raised future revenue growth estimates. The company’s international segments also contributed to earnings as investments overseas continued to pay off. Similarly, the Fund’s holdings of Abbvie Inc., a pharmaceuticals developer and manufacturer, contributed to performance. The company’s stock

2

advanced as challenges to its important Humira patent were rejected and Trump’s presidential victory was viewed positively for pharmaceuticals, with Hillary Clinton’s proposed reforms now less likely to succeed.

Conversely, the Fund’s stock selection in the consumer staples sector detracted from relative performance. Within consumer staples, shares of CVS Health Corp., an integrated pharmacy health care services company, detracted from performance. The company’s shares declined, reflecting a lower profit outlook following the projected loss of significant retail prescriptions due to new retail pharmacy networks that are excluding CVS pharmacy drug stores. Also detracting from relative performance were shares of Kimberly-Clark Corp., a global health and hygiene company, which declined during the period. The company reported third

quarter 2016 earnings that missed expectations with lower organic sales growth than estimated. Foreign exchange changes also adversely impacted the company as management cited a more challenging economic and competitive environment.

The Fund’s underweight to the financials sector also detracted from relative performance during the year. After a challenging start to the year, the sector performed strongly following Trump’s presidential victory and market expectations for stronger growth, higher inflation, and reduced regulations.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹ The S&P 500^® Index is widely regarded as the standard for measuring large cap U.S. stock market performance and includes a representative sample of leading companies in leading industries.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer own the securities described above or may have otherwise changed their positions in the securities. For more recent information about the Fund’s portfolio holdings, please visit www.lordabbett.com.

A Note about Risk: See Notes to Financial Statements for a discussion of investment risks. For a more detailed discussion of the risks associated with each Fund, please see the Fund’s prospectus.

Mutual funds are not insured by the FDIC, are not deposits or other obligations of, or guaranteed by, banks, and are subject to investment risks including possible loss of principal amount invested.

The Fund serves as an underlying investment vehicle for variable annuity contracts and variable life insurance policies.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the S&P 500^® Index and the S&P 900^® 10-Year Dividend Growth Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. The line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During certain periods, expenses of the Fund have been waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

The S&P 900^® 10-Year Dividend Growth Index is a custom index that, along with changes in the Fund’s investment strategy, the Fund began disclosing in its prospectus effective September 27, 2012.

Average Annual Total Returns for the Periods Ended December 31, 2016
	1 Year	5 Years	10 Years
Class VC	15.10%	12.57%	6.92%

¹ Performance for the unmanaged index does not reflect transaction costs, management fees or sales charges. The performance of the index is not necessarily representative of the Fund’s performance.

² Performance for the unmanaged index does not reflect transaction costs, management fees or sales charges. The performance of the index is not necessarily representative of the Fund’s performance. Performance for the index began on September 27, 2012.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

6

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value	Ending Account Value	Expenses Paid During Period†
			7/1/16 -
	7/1/16	12/31/16	12/31/16
Class VC
Actual	$1,000.00	$1,034.60	$4.35
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,020.86	$4.32

^† Net expenses are equal to the Fund’s annualized expense ratio of 0.85%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION  

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Calibrated Dividend Growth Portfolio (the “Fund”).

The Fund’s investment objective is to seek current income and capital appreciation. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices. Exchange traded options and futures contracts are valued at the last sale price in the market where they are principally traded. If no sale has occurred, the mean between the most recently quoted bid and asked prices is used.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.

18

Notes to Financial Statements (continued)

	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.
(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on futures contracts and translation of assets and liabilities denominated in foreign currencies in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized gain on futures contracts and foreign currency related transactions in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Futures Contracts–The Fund may purchase and sell index futures contracts to manage cash, or as a substitute position in lieu of holding the underlying asset on which the instrument is based. At the time of entering into a futures transaction, an investor is required to deposit and maintain a specified amount of cash or eligible securities called “initial margin.” Subsequent payments made or received by the Fund called “variation margin” are made on a daily basis as the market price of the futures contract fluctuates. The Fund will record an unrealized gain (loss) based on the amount of variation margin. When a contract is closed, a realized gain (loss) is recorded equal to the difference between the opening and closing value of the contract.
(h)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an

19

Notes to Financial Statements (continued)

agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.

(i)

Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk – for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

• Level 1 – unadjusted quoted prices in active markets for identical investments;

• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and

• Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments and other financial instruments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

20

Notes to Financial Statements (continued)

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.75%
Next $1 billion	.70%
Over $2 billion	.65%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of .35% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses to an annual rate of .85%. This agreement may be terminated only upon the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended 12/31/2016		Year Ended 12/31/2015
Distributions paid from:
Ordinary income	$	4,821,625	$	5,299,556
Net long-term capital gains		8,282,898		6,242,510
Total distributions paid	$	13,104,523	$	11,542,066

21

Notes to Financial Statements (continued)

As of December 31, 2016, the components of accumulated gains on a tax-basis were as follows:

Undistributed ordinary income – net	$	1,216,635
Undistributed long-term capital gains		696,061
Total undistributed earnings		1,912,696
Temporary differences		(20,203	)
Unrealized gains – net		4,866,095
Total accumulated gains – net	$	6,758,588

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	166,319,915
Gross unrealized gain		8,066,778
Gross unrealized loss		(3,200,683	)
Net unrealized security gain	$	4,866,095

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to wash sales.

5. PORTFOLIO SECURITIES TRANSACTIONS  

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases	Sales
$157,793,354	$108,703,756

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES  

The Fund entered into E-Mini S&P 500 Index futures contracts for the fiscal year ended December 31, 2016 (as described in note 2(g)) to manage cash. The Fund bears the risk that the underlying index will move unexpectedly, in which case the Fund may realize a loss. There is minimal counterparty credit risk to the Fund since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees futures against default.

As of December 31, 2016, the Fund had futures contracts with unrealized depreciation of $(4,125), which is included in the Schedule of Investments. Only current day’s variation margin is reported within the Fund’s Statement of Assets and Liabilities. Amounts of $146,195 and $164 are included in the Statement of Operations related to futures contracts under the captions Net realized gain on futures contracts and Net change in unrealized appreciation/depreciation on futures contracts, respectively. The average number of futures contracts throughout the period was 10.

7. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash

22

Notes to Financial Statements (continued)

collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

			Gross Amounts		Net Amounts of
			Offset in the		Assets Presented
	Gross Amounts of		Statement of Assets		in the Statement of
Description	Recognized Assets		and Liabilities		Assets and Liabilities
Repurchase Agreement		$1,684,987	$	–		$1,684,987
Total		$1,684,987	$	–		$1,684,987

	Net Amounts
	of Assets		Amounts Not Offset in the
	Presented in		Statement of Assets and Liabilities
	the Statement				Cash		Securities
	of Assets and		Financial		Collateral		Collateral			Net
Counterparty	Liabilities		Instruments		Received(a)		Received(a)			Amount(b)
Fixed Income Clearing Corp.		$1,684,987	$	–	$	–		$(1,684,987	)	$	–
Total		$1,684,987	$	–	$	–		$(1,684,987	)	$	–

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

8. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

9. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

10. LINE OF CREDIT  

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million,

23

Notes to Financial Statements (concluded)

or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

11. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

12. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

13. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with equity investing. The Fund invests primarily in equity securities of large and mid-sized company stocks that have a history of growing their dividends, but there is no guarantee that a company will pay a dividend. The value of the Fund’s investments in equity securities will fluctuate in response to general economic conditions and to the changes in the prospects of particular companies and/or sectors in the economy. If the Fund’s fundamental research and quantitative analysis fail to produce the intended result, the Fund may suffer losses or underperform its benchmark or other funds with the same investment objective or similar strategies, even in a rising market.

Large and mid-sized company stocks each may perform differently than the market as a whole and other types of stocks. This is because different types of stocks tend to shift in and out of favor depending on market and economic conditions. Mid-sized company stocks may be less able to weather economic shifts or other adverse developments than those of larger, more established companies.

The Fund’s exposure to foreign companies and markets presents increased market, liquidity, currency, political and other risks.

These factors can affect the Fund’s performance.

14. SUMMARY OF CAPITAL TRANSACTIONS  

Transactions in shares of capital stock were as follows:

	Year Ended			Year Ended
	December 31, 2016			December 31, 2015
Shares sold		6,045,995			2,104,100
Reinvestment of distributions		893,876			827,804
Shares reacquired		(2,821,771	)		(2,817,767	)

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Calibrated Dividend Growth Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Calibrated Dividend Growth Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Calibrated Dividend Growth Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year, three-year and ten-year periods and

31

Approval of Advisory Contract (continued)

below the median of the performance peer group for the five-year period. The Board also considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than

32

Approval of Advisory Contract (concluded)

investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

Director, President and Chief Executive Officer

For the fiscal year ended December 31, 2016, the Fund returned 12.44%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the Russell 1000^® Index,¹ which returned 12.05% over the same period.

Domestic equity markets (as represented by the S&P 500^® Index²) returned 11.96% over the past year. Despite this general move higher, there were significant bouts of volatility within U.S. stock markets, including their worst start to a calendar year on record.

Crude oil prices played a significant role in the increased market volatility, as Brent oil prices fluctuated sharply throughout the fiscal year. In December, the Organization of Petroleum Exporting Countries (OPEC) agreed to reduce oil production effective 2017. Furthermore, global markets were affected by the devaluation of China’s currency and weak economic data out of the region. The Chinese economy advanced at an annual rate of 6.7% in the third quarter of 2016, a slower pace than in recent years.

1

Geopolitical events also contributed to volatility in global markets. The United Kingdom’s referendum in June to leave the European Union (“Brexit”) was a surprise that caused a sell-off in global markets.

In contrast to the equity market volatility, the U.S. economy continued to expand during the trailing 12-month period. The Federal Reserve (Fed) raised target rates in for the second time in 12 months in December, from 0.25%–0.50% to 0.50%–0.75%. U.S. gross domestic product (GDP) grew at a 3.2% pace during the third quarter, a significant increase over the second quarter. The U.S. Bureau of Economic Analysis stated that during the third-quarter personal consumption and federal government spending increased, quarter over quarter. In addition to GDP growth, the U.S. unemployment rate remained relatively steady throughout the period, and was reported at 4.6% in November.

The U.S. presidential election took an unexpected turn as Donald J. Trump was elected president, in contrast to indications from poll numbers before the election. Markets rallied on improved clarity in the U.S. political agenda, with the House and Senate also under Republican control.

The Fund modestly outperformed its index during the period. The largest contributors to relative performance during the 12-month period were the heath care and energy sectors. Within the health care sector, shares of UnitedHealth Group Inc., a diversified health and well-being company, rose in the fourth quarter

due to increased momentum in Medicare Advantage enrollment and 2017 earnings guidance that was well above consensus estimates. Shares of St. Jude Medical, Inc., a developer, manufacturer, and distributor of cardiovascular medical devices, surged in late April after it was announced that the company would be acquired by Abbott Laboratories at a substantial premium to its previous closing price, which validated our investment thesis that St. Jude’s underlying assets were more valuable than its share price implied. Within the energy sector, shares of Devon Energy Corp., a North American energy exploration and production company, rose as the company took several steps in 2016 to strengthen its balance sheet, including sale of valuable, but non-core, assets, which helped its shares rise as investors recognized this financial improvement. Shares of EOG Resources, Inc., an explorer, developer, producer, and marketer of natural gas and crude oil, also rose after the company released strong second quarter earnings and growth estimates. The company also advanced in the fourth quarter following OPEC’s agreement to reduce oil production for the first time in eight years.

The largest detractors to relative performance during the trailing 12-month period were the consumer staples and materials sectors. Within the consumer staples sector, shares of CVS Health Corporation, a pharmacy and health care company, fell after the California Public Employee’s Retirement System switched

2

their PBM (pharmacy benefit manager) contract to United Healthcare’s OptumRx. CVS was further hurt during the fourth quarter after the company revised its 2017 guidance expectations, which were well below consensus estimates. Shares of Colgate-Palmolive Co., a manufacturer and seller of consumer products, fell as the company experienced challenges from slower growth due to the headwinds from the macro-economic environment and pressures from competitors in China and India. Within the materials sector, shares of PPG Industries Inc., a manufacturer and distributor of coatings, specialty materials, and glass products, dropped as the

company’s large international exposure created challenges due to the uncertainty of macro-economic conditions, foreign exchange headwinds, and rising prices of raw materials. Shares of Dow Chemical Co., a diversified chemical company that provides chemical, plastic, and agricultural products and services to various customer markets, fell due to investor concerns of a potential global recession following “Brexit”.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹  The Russell 1000^® Index measures the performance of the 1,000 largest companies in the Russell 3000 Index, which represent approximately 92% of the total market capitalization of the Russell 3000 Index.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in both the Russell 1000^® Index and the S&P 500^® Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. This line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or Fund shares. During certain periods, expenses of the Fund have been waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning	Ending	Expenses
	Account	Account	Paid During

Hypothetical (5% Return Before Expenses)	$1,000.00	$1,020.36	$4.82

^† Net expenses are equal to the Fund’s annualized expense ratio of 0.95%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION 

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Classic Stock Portfolio (the “Fund”).

The Fund’s investment objective is growth of capital and growth of income consistent with reasonable risk. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES 

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.

16

Notes to Financial Statements (continued)

(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on investments in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized gain on investments in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.
(h)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable

17

Notes to Financial Statements (continued)

inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

•	Level 1 –	unadjusted quoted prices in active markets for identical investments;
•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES 

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.70%
Next $1 billion	.65%
Over $2 billion	.60%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of .32% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary

18

Notes to Financial Statements (continued)

to limit total net annual operating expenses, to an annual rate of ..95%. This agreement may be terminated only upon the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS 

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended 12/31/2016		Year Ended 12/31/2015
Distributions paid from:
Ordinary income	$	442,540	$	305,595
Net long-term capital gains		1,677,064		6,419,296
Total distributions paid	$	2,119,604	$	6,724,891

As of December 31, 2016, the components of accumulated gains on a tax-basis were as follows:

Undistributed ordinary income – net	$	5,787
Undistributed long-term capital gains		685,043
Total undistributed earnings		690,830
Temporary differences		(6,008	)
Unrealized gains – net		4,160,472
Total accumulated gains – net	$	4,845,294

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Notes to Financial Statements (continued)

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to the tax treatment of certain distributions received and wash sales.

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Distributions in	Accumulated
Excess of Net	Net Realized
Investment Income	Gain
$(36,120)	$36,120

The permanent differences are attributable to the tax treatment of certain distributions received.

5. PORTFOLIO SECURITIES TRANSACTIONS 

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases	Sales
$45,795,535	$39,309,303

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES 

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

Description	Gross Amounts of Recognized Assets		Gross Amounts Offset in the Statement of Assets and Liabilities		Net Amounts of Assets Presented in the Statement of Assets and Liabilities
Repurchase Agreement		$938,800	$	–		$938,800
Total		$938,800	$	–		$938,800

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

7. DIRECTORS’ REMUNERATION 

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

8. EXPENSE REDUCTIONS 

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

9. LINE OF CREDIT 

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

10. INTERFUND LENDING PROGRAM 

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

21

Notes to Financial Statements (concluded)

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

11. CUSTODIAN AND ACCOUNTING AGENT 

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

12. INVESTMENT RISKS 

The Fund is subject to the general risks and considerations associated with equity investing, as well as the particular risks associated with value and growth stocks. This means the value of your investment will fluctuate in response to movements in the equity securities market in general and to the changing prospects of individual companies in which the Fund invests. Large-cap value and growth stocks may perform differently than the market as a whole and differently than each other or other types of stocks, such as small company stocks. This is because different types of stocks tend to shift in and out of favor depending on market and economic conditions. The market may fail to recognize the intrinsic value of particular value stocks for a long time. Growth stocks may be more volatile than other stocks. In addition, if the Fund’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is wrong, the Fund could suffer losses or produce poor performance relative to other funds, even in a rising market.

Due to its investment exposure to foreign companies and American Depositary Receipts, the Fund may experience increased market, liquidity, currency, political, information, and other risks.

These factors can affect the Fund’s performance.

13. SUMMARY OF CAPITAL TRANSACTIONS 

Transactions in shares of capital stock were as follows:

	Year Ended December 31, 2016	Year Ended December 31, 2015
Shares sold	2,570,120	1,904,507
Reinvestment of distributions	169,122	558,469
Shares reacquired	(2,011,279)	(2,638,654	)
Increase (decrease)	727,963	(175,678	)

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Classic Stock Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Classic Stock Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Classic Stock Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally.The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance.The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year, three-year and ten-year periods and below the median of the performance peer group for the five-year period. The Board also considered Lord

29

Approval of Advisory Contract (continued)

Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods.The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability.The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale.The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett.The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible

30

Approval of Advisory Contract (concluded)

benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements.The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

31

Householding

The Company has adopted a policy that allows it to send only one copy of the Fund’s prospectus, proxy material, annual report and semiannual report to certain shareholders residing at the same “household.” This reduces Fund expenses, which benefits you and other shareholders. If you need additional copies or do not want your mailings to be “householded,” please call Lord Abbett at 888-522-2388 or send a written request with your name, the name of your fund or funds and your account number or numbers to Lord Abbett Family of Funds, P.O.

For the fiscal year ended December 31, 2016, the Fund returned -2.60%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the Russell 2000 Growth^® Index¹, which returned 11.32% over the same period.

Domestic equity markets (as represented by the S&P 500^® Index²) returned 11.96% over the past year. Despite this general move higher, there were significant bouts of volatility within U.S. stock markets, including their worst start to a calendar year on record.

Crude oil prices played a significant role in the increased market volatility, as Brent oil prices fluctuated sharply throughout the fiscal year. In December, the Organization of Petroleum Exporting Countries agreed to reduce oil production effective 2017. Furthermore, global markets were affected by the devaluation of China’s currency and weak economic data out of the region. The Chinese economy advanced at an annual rate of 6.7% in the third quarter of 2016, a slower pace than in recent years.

1

Geopolitical events also contributed to volatility in global markets. The United Kingdom’s referendum in June to leave the European Union (“Brexit”) was a surprise that caused a sell-off in global markets.

In contrast to the equity market volatility, the U.S. economy continued to expand during the trailing 12-month period. The Federal Reserve (Fed) raised target rates for the second time in 12 months in December, from 0.25%–0.50% to 0.50%–0.75%. U.S. gross domestic product (GDP) grew at a 3.2% pace during the third quarter, a significant increase over the second quarter. The U.S. Bureau of Economic Analysis stated that during the third-quarter personal consumption and federal government spending increased, quarter over quarter. In addition to GDP growth, the U.S. unemployment rate remained relatively steady throughout the period, and was reported at 4.6% in November.

The U.S. presidential election took an unexpected turn as Donald J. Trump was elected president, in contrast to indications from poll numbers before the election. Markets rallied on improved clarity in the U.S. political agenda, with the House and Senate also under Republican control.

The leading detractor from the Fund’s performance relative to the benchmark during the period was stock selection within the information technology sector. Within this sector, the Fund’s position in SunPower Corp., a global energy company, was a primary detractor. Shares of SunPower fell during the period as the company failed to

deliver on second quarter earnings expectations and lowered future revenue and margin guidance. Another detractor within the sector was the Fund’s position in Gogo, Inc., a provider of in-flight connectivity and wireless entertainment solutions. Shares of Gogo fell as the company reported mixed results for third quarter 2016; the growth of its average revenue per aircraft was expected to slow.

Stock selection in the industrials sector was another detractor from the Fund’s performance relative to the benchmark during the period. Within this sector, the Fund’s holdings of Dycom Industries, Inc., a North American provider of specialty contracting services, detracted most. Dycom experienced a pause in fiber deployment from an unnamed customer, which had a significant effect on its fiscal fourth quarter revenue.

The leading contributor to the Fund’s relative performance during the reporting period was security selection in the health care sector. Within this sector, the Fund’s holdings of Exelixis, Inc., a biopharmaceutical company, contributed most. Shares of Exelixis rose as its kidney cancer treatment, CABOMETYX, was approved in Europe. Another contributor within this sector over the past year was the Fund’s position in ZELTIQ Aesthetics, Inc., a medical technology company. Shares of ZELTIQ Aesthetics rose as improvements in its utilization and international growth helped it beat third quarter revenue and earnings expectations.

2

An underweight in the real estate sector also positively impacted the portfolio’s relative performance during the period. The real estate sector was negatively impacted by investors’ shift away from income-oriented securities, as the probability of a December Federal Reserve rate hike increased and ultimately materialized.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹ The Russell 2000^® Growth Index measures the performance of those Russell 2000 companies with higher price-to-book ratios and higher forecasted growth values.

² The S&P 500^® Index is widely regarded as the standard for measuring large cap U.S. stock market performance and includes a representative sample of leading companies in leading industries.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer own the securities described above or may have otherwise changed their positions in the securities. For more recent information about the Fund’s portfolio holdings, please visit www.lordabbett.com.

A Note about Risk: See Notes to Financial Statements for a discussion of investment risks. For a more detailed discussion of the risks associated with each Fund, please see the Fund’s prospectus.

Mutual funds are not insured by the FDIC, are not deposits or other obligations of, or guaranteed by, banks, and are subject to investment risks including possible loss of principal amount invested.

The Fund serves as an underlying investment vehicle for variable annuity contracts and variable life insurance policies.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the Russell 2000^® Growth Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. The line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would belower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During the period, expenses of the Fund were waivedor reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

Average Annual Total Returns for the Periods Ended December 31, 2016
	1 Year	5 Years	Life of Class
Class VC2	–2.60%	10.25%	10.79%

¹ Performance for the unmanaged index does not reflect any fees or expenses. The performance of the index is not necessarily representative of the Fund’s performance. Performance for the index began on May 1, 2010.

² The Class VC shares commenced operations on April 23, 2010. Performance for the Class began on May 1, 2010.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value	Ending Account Value	Expenses Paid During Period†
	7/1/16	12/31/16	7/1/16 - 12/31/16
Class VC
Actual	$1,000.00	$1,063.20	$4.67
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,020.61	$4.57

^† Net expenses are equal to the Fund’s annualized expense ratio of 0.90%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION  

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Developing Growth Portfolio (the “Fund”).

The Fund’s investment objective is long-term growth of capital. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.

16

Notes to Financial Statements (continued)

(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on investments in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized loss on investments in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.
(h)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs

17

Notes to Financial Statements (continued)

refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

Level 1 –	unadjusted quoted prices in active markets for identical investments;
Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $100 million	.75%
Over $100 million	.50%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of 0.14% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of ..04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses to an annual rate of 0.90%. This agreement may be terminated only upon the approval of the Board.

18

Notes to Financial Statements (continued)

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended 12/31/2016		Year Ended 12/31/2015
Distributions paid from:
Ordinary income	$	–	$	187,754
Net long-term capital gains		–		47,612
Total distributions paid	$	–	$	235,366

As of December 31, 2016, the components of accumulated losses on a tax-basis were as follows:

Capital loss carryforwards*	$	(3,966,903	)
Temporary differences		(1,760	)
Unrealized gains – net		1,267,707
Total accumulated losses – net	$	(2,700,956	)

* The capital losses will carry forward indefinitely.

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	27,054,131
Gross unrealized gain		2,009,432
Gross unrealized loss		(741,725	)
Net unrealized security gain	$	1,267,707

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to wash sales.

19

Notes to Financial Statements (continued)

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Accumulated Net Investment Loss	Accumulated Net Realized Loss	Paid-in Capital
$103,382	$893	$(104,275	)

The permanent differences are attributable to the tax treatment of net investment losses and certain distributions received.

5. PORTFOLIO SECURITIES TRANSACTIONS  

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases	Sales
$66,548,581	$66,528,730

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty. As of December 31, 2016, the Fund did not have assets or liabilities subject to the FASB disclosure requirements.

7. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

20

Notes to Financial Statements (continued)

8. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

9. LINE OF CREDIT  

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

10. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

11. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

12. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with equity investing. The value of an investment will fluctuate in response to movements in the equity securities markets in general and to the changing prospects of individual companies in which the Fund invests.

The Fund has particular risks associated with growth stocks. Different types of stocks shift in and out of favor depending on market and economic conditions. Growth stocks tend to be more volatile than other stocks. In addition, if the Fund’s assessment of a company’s potential for growth or market conditions is wrong, it could suffer losses or produce poor performance relative to other funds, even in a rising market. The Fund invests primarily in small-cap growth company stocks, which tend to be more volatile and can be less liquid than other types of stocks. Small-cap companies may also have more limited product lines, markets or financial resources, and typically experience a higher risk of failure than large-cap companies. Because the Fund may invest a portion of its assets in foreign securities and American Depositary Receipts, it may experience increased market, liquidity, currency, political, information and other risks.

21

Notes to Financial Statements (concluded)

These factors can affect the Fund’s performance.

13. SUMMARY OF CAPITAL TRANSACTIONS  

Transactions in shares of capital stock were as follows:

	Year Ended December 31, 2016			Year Ended December 31, 2015
Shares sold		738,518			905,924

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Developing Growth Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Developing Growth Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Developing Growth Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of the Fund’s benchmark; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and the Fund’s benchmark as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was below the median of the performance peer group for the one-year, three-year and five-year periods. The Board noted a presentation on investment performance by Lord Abbett, which, among other things, indicated the

29

Approval of Advisory Contract (continued)

Fund’s “high growth” style may have impacted its relative ranking in the performance peer group. The Board also considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoint in the level of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than

30

Approval of Advisory Contract (concluded)

investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

For the fiscal year ended December 31, 2016, the Fund returned 15.74%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the Russell 1000^® Value Index¹, which returned 17.34% over the same period.

Domestic equity markets (as represented by the S&P 500^® Index²) returned 11.96% over the past year. Despite this general move higher, there were significant bouts of volatility within U.S. stock markets, including their worst start to a calendar year on record.

Crude oil prices played a significant role in the increased market volatility, as Brent oil prices fluctuated sharply throughout the fiscal year. In December, the Organization of Petroleum Exporting Countries agreed to reduce oil production effective 2017. Furthermore, global markets were affected by the devaluation of China’s currency and weak economic data out of the region. The Chinese economy advanced at an annual rate of 6.7% in the third quarter of 2016, a slower pace than in recent years.

1

Geopolitical events also contributed to volatility in global markets. The United Kingdom’s referendum in June to leave the European Union (“Brexit”) was a surprise that caused a sell-off in global markets.

In contrast to the equity market volatility, the U.S. economy continued to expand during the trailing 12-month period. The Federal Reserve (Fed) raised target rates in for the second time in 12 months in December, from 0.25%–0.50% to 0.50%–0.75%. U.S. gross domestic product (GDP) grew at a 3.2% pace during the third quarter, a significant increase over the second quarter. The U.S. Bureau of Economic Analysis stated that during the third-quarter personal consumption and federal government spending increased, quarter over quarter. In addition to GDP growth, the U.S. unemployment rate remained relatively steady throughout the period, finishing at 4.6% in November.

The U.S. presidential election took an unexpected turn as Donald J. Trump was elected president, in contrast to indications from poll numbers before the election. Markets rallied on improved clarity in the U.S. political agenda, with the House and Senate also under Republican control.

The Fund underperformed its benchmark during the period. During the trailing 12-month period, stock selection within the materials and consumer staples sectors detracted from relative performance the most. Within the materials sector, shares of E.I. DuPont de Neumours and Co., a science and

technology-based company, declined as the company faced fundamental headwinds from agriculture volatility, weaker global currencies, and slowing industrial production. Shares of Reliance Steel & Aluminum Co., a metals service center company, also fell during the third quarter due to lower-than-expected steel prices and easing of the company’s gross margins. Within the consumer staples sector, shares of CVS Health Corporation, a pharmacy and health care company, fell after the California Public Employee’s Retirement System switched their PBM (pharmacy benefit manager) contract to United Healthcare’s OptumRx. CVS was further hurt during the fourth quarter after the company revised its 2017 guidance expectations, which were well below consensus estimates. Shares of Kroger Co., an operator of retail food and drug stores, also dropped, as meat and dairy prices deflated and competition offering discounted prices accelerated.

The largest contributors to relative performance during the trailing 12-month period were the health care and financials sectors. Within the health care sector, shares of UnitedHealth Group Inc., a diversified health and well-being company, rose in the fourth quarter due to increased momentum in Medicare Advantage enrollment and 2017 earnings guidance that was well above consensus estimates. Shares of Johnson & Johnson, a developer, manufacturer, and seller of consumer health care products, spiked from

2

improving fundamentals, strong organic growth, and better than estimated earnings and sales during the second quarter. Within the financials sector, shares of Citizens Financial Group, Inc., a retail and commercial bank holdings company, rose, reflecting the company’s continuous profitability improvement and the anticipation for higher interest rates and a better U.S. economy following the presidential election. Shares of J.P. Morgan Chase & Co., a financial services and retail

banking company, also rose after the presidential election due to the anticipation of a better macro-economic environment with higher rates, less regulation, and lower taxes.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹  The Russell 1000^® Value Index measures the performance of those Russell 1000 companies with lower price-to-book ratios and lower forecasted growth values.

²  The S&P 500^® Index is widely regarded as the standard for measuring large cap U.S. stock market performance and includes a representative sample of leading companies in leading industries.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense

waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer own the securities described above or may have otherwise changed their positions in the securities.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the Russell 1000^® Value Index, Russell 3000^® Index, Russell 3000^® Value Index, and S&P 500^® Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. This line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During certain periods, expenses of the Fund have been waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

 

	Average Annual Total Returns for the Periods Ended December 31, 2016
	1 Year		5 Years		10 Years

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning		Ending		Expenses
	Account		Account		Paid During

					7/1/16 -

Hypothetical (5% Return Before Expenses)	$	1,000.00	$	1,019.36	$	5.84

^†  Net expenses are equal to the Fund’s annualized expense ratio of 1.15%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION  

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Fundamental Equity Portfolio (the “Fund”).

The Fund’s investment objective is long-term growth of capital and income without excessive fluctuations in market value. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2.	SIGNIFICANT ACCOUNTING POLICIES
(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.

16

Notes to Financial Statements (continued)

	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.
(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on investments in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized gain on investments in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.

17

Notes to Financial Statements (continued)

(h) Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances.The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

• Level 1 – unadjusted quoted prices in active markets for identical investments;

• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and

• Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.75	%
Next $1 billion	.70	%
Over $2 billion	.65	%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of .70% of the Fund’s average daily net assets.

18

Notes to Financial Statements (continued)

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses to an annual rate of 1.15%. This agreement may be terminated only upon the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to ..25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended 12/31/2016		Year Ended 12/31/2015
Distributions paid from:
Ordinary income	$	9,867,397	$	5,438,690
Net long-term capital gains		1,517,940		22,224,761
Total distributions paid	$	11,385,337	$	27,663,451

As of December 31, 2016, the components of accumulated gains on a tax-basis were as follows:

Undistributed ordinary income – net	$	3,204,712
Total undistributed earnings		3,204,712
Temporary differences		(48,682	)
Unrealized gains – net		32,666,216
Total accumulated gains – net	$	35,822,246

19

Notes to Financial Statements (continued)

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	352,484,600
Gross unrealized gain		37,042,991
Gross unrealized loss		(4,376,775	)
Net unrealized security gain	$	32,666,216

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to wash sales.

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Distributions in Excess of Net Investment Income			Accumulated Net Realized Loss
	$(243,168	)		$243,168

The permanent differences are attributable to the tax treatment of certain distributions.

5. PORTFOLIO SECURITIES TRANSACTIONS  

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases		Sales
$	510,433,719	$	432,022,950

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

Description	Gross Amounts of Recognized Assets		Gross Amounts Offset in the Statement of Assets and Liabilities		Net Amounts of Assets Presented in the Statement of Assets and Liabilities
Repurchase Agreement		$4,116,402	$	–	$	4,116,402
Total		$4,116,402	$	–	$	4,116,402

Notes to Financial Statements (continued)

	Net Amounts of Assets Presented in		Amounts Not Offset in the Statement of Assets and Liabilities
Counterparty	the Statement of Assets and Liabilities		Financial Instruments		Cash Collateral Received(a)		Securities Collateral Received(a)			Net Amount(b)
Fixed Income Clearing Corp.	$	4,116,402	$	–	$	–	$	(4,116,402	)	$	–
Total	$	4,116,402	$	–	$	–	$	(4,116,402	)	$	–

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

7. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

8. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

9. LINE OF CREDIT  

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

10. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

21

Notes to Financial Statements (concluded)

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

11. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

12. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with investing in equity securities as well as the particular risks associated with value stocks. The value of an investment will fluctuate in response to movements in the equity securities market in general and to the changing prospects of individual companies in which the Fund invests. Large value stocks, in which the Fund invests a significant portion of its assets, may perform differently than the market as a whole and other types of stocks, such as mid-sized or small-company stocks and growth stocks. This is because different types of stocks tend to shift in and out of favor depending on market and economic conditions. Mid-cap and small-cap company stocks in which the Fund may invest may be more volatile and less liquid than large-cap stocks. The market may fail to recognize the intrinsic value of a particular value stock for a long time. In addition, if the Fund’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is wrong, the Fund could suffer losses or produce poor performance relative to other funds, even in a rising market.

Due to the Fund’s investment exposure to foreign companies and American Depositary Receipts, the Fund may experience increased market, liquidity, currency, political, information, and other risks.

The Fund is subject to the risks associated with derivatives, which may be different and greater than the risks associated with investing directly in securities and other investments.

These factors can affect the Fund’s performance.

13. SUMMARY OF CAPITAL TRANSACTIONS  

Transactions in shares of capital stock were as follows:

	Year Ended December 31, 2016			Year Ended December 31, 2015
Shares sold		15,238,804			10,986,185

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Fundamental Equity Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Fundamental Equity Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Fundamental Equity Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016 the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year, three-year and ten-year periods and below the median of the performance peer group for the five-year period. The Board also

29

Approval of Advisory Contract (continued)

considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was above the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable in light of the long-term performance of the Fund and the quality of the services received.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord

30

Approval of Advisory Contract (concluded)

Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

31

Householding

The Company has adopted a policy that allows it to send only one copy of the Fund’s prospectus, proxy material, annual report and semiannual report to certain shareholders residing at the same “household.” This reduces Fund expenses, which benefits you and other shareholders.

Box 219336, Kansas City, MO 64121.

Lord Abbett Series Fund — Growth and Income Portfolio Annual Report

For the fiscal year ended December 31, 2016

  From left to right: James L.L. Tullis, Chairman of the Lord Abbett Funds and Daria L. Foster Director, President, and Chief Executive Officer of the Lord Abbett Funds. Dear Shareholders: We are pleased to provide you with this overview of the performance of Lord Abbett Series Fund — Growth & Income Portfolio for the fiscal year ended December 31, 2016. On this page and the following pages, we discuss the major factors that influenced fiscal year performance. For additional information about the Fund, please visit our website at www.lordabbett.com, where you also can access the quarterly commentaries that provide updates on the Fund’s performance and other portfolio related updates. Thank you for investing in Lord Abbett mutual funds. We value the trust that you place in us and look forward to serving your investment needs in the years to come.   Best regards,     Daria L. Foster Director, President and Chief Executive Officer

For the fiscal year ended December 31, 2016, the Fund returned 17.11%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the Russell 1000^® Value Index,¹ which returned 17.34% over the same period.

Domestic equity markets (as represented by the S&P 500^® Index²) returned 11.96% over the past year. Despite this general move higher, there were significant bouts of volatility within U.S. stock markets, including their worst start to a calendar year on record.

Crude oil prices played a significant role in the increased market volatility, as Brent oil prices fluctuated sharply throughout the fiscal year. In December, the Organization of Petroleum Exporting Countries agreed to reduce oil production effective 2017. Furthermore, global markets were affected by the devaluation of China’s currency and weak economic data out of the region. The Chinese economy advanced at an annual rate of 6.7% in the third quarter of 2016, a slower pace than in recent years.

Geopolitical events also contributed to volatility in global markets. The United Kingdom’s referendum in June to leave the European Union (“Brexit”) was a surprise that caused a sell-off in global markets.

In contrast to the equity market volatility, the U.S. economy continued to expand during the trailing 12-month period. The Federal Reserve (Fed) raised target rates in for the second time in 12 months in December, from 0.25%–0.50% to 0.50%–0.75%. U.S. gross domestic product (GDP) grew at a 3.2% pace during the third quarter, a significant increase over the second quarter. The U.S. Bureau of Economic Analysis stated that during the third-quarter personal consumption and federal government spending increased, quarter over quarter. In addition to GDP growth, the U.S. unemployment rate remained relatively steady throughout the period, finishing at 4.6% in November.

The U.S. presidential election took an unexpected turn as Donald J. Trump was elected president, in contrast to indications from poll numbers before the election. Markets rallied on improved clarity in the U.S. political agenda, with the House and Senate also under Republican control.

The Fund modestly underperformed its benchmark index for the period. During the trailing 12-month period, the materials and consumer staples sectors detracted from relative performance the most. Within the materials sector, shares of E.I. DuPont de Neumours and Co., a science and technology-based company, declined as the

company faced fundamental headwinds from agriculture volatility, weaker global currencies, and slowing industrial production. Shares of Reliance Steel & Aluminum Co., a metals service center company, also fell during the third quarter due to lower-than-expected steel prices and easing of the company’s gross margins. Within the consumer staples sector, shares of CVS Health Corporation, a pharmacy and health care company, fell after the California Public Employee’s Retirement System switched their PBM (pharmacy benefit manager) contract to United Healthcare’s OptumRx. CVS was further hurt during the fourth quarter after the company revised its 2017 guidance expectations, which were well below consensus estimates. Shares of Kroger Co., an operator of retail food and drug stores, also dropped, as meat and dairy prices deflated and competition offering discounted prices accelerated.

The largest contributor to relative performance during the trailing 12-month period was the financials sector. Shares of J.P. Morgan Chase & Co., a financial services and retail banking company, rose after the presidential election due to the anticipation of a better macro-economic environment with higher rates, less regulation, and lower taxes. Shares of Citizens Financial Group, Inc., a retail and commercial bank holdings company, also rose reflecting the company’s continuous profitability improvement and the anticipation for higher interest rates and a better U.S. economy following the presidential election.

2

Another contributor to relative performance during the trailing 12-month period was the Fund’s underweight to the real estate sector, as the sector performed the worst in the index over the timeframe.

The heath care sector also contributed to relative performance during the trailing 12-month period. Within the health care sector, shares of UnitedHealth Group Inc., a diversified health and well-being company, rose in the fourth quarter due to increased momentum in Medicare Advantage enrollment and 2017 earnings guidance that

was well above consensus estimates. Shares of Johnson & Johnson, a developer, manufacturer, and seller of consumer health care products, spiked as a result of improving fundamentals, strong organic growth, and better-than-estimated earnings and sales during the second quarter.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹ The Russell 1000^® Value Index measures the performance of those Russell 1000 companies with lower price-to-book ratios and lower forecasted growth values.

² The S&P 500^® Index is widely regarded as the standard for measuring large cap U.S. stock market performance and includes a representative sample of leading companies in leading industries.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the Russell 1000^® Value Index, the S&P 500^® Index and the S&P 500^® Value Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. This line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Past performance is no guarantee of future results.

	Average Annual Total Returns for the
	Periods Ended December 31, 2016
	1 Year	5 Years	10 Years
Class VC	17.11%	13.28%	4.87%

¹ Performance for each unmanaged index does not reflect any fees or expenses. The performance of each index is not necessarily representative of the Fund’s performance.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value	Ending Account Value	Expenses Paid During Period†
	7/1/16	12/31/16	7/1/16 - 12/31/16
Class VC
Actual	$1,000.00	$1,116.70	$5.00
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,020.41	$4.77

^† Net expenses are equal to the Fund’s annualized expense ratio of 0.94%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION   

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Growth and Income Portfolio (the “Fund”).

The Fund’s investment objective is long-term growth of capital and income without excessive fluctuations in market value. The Fund’s Variable Contract class shares (“Class VC Shares”), are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES   

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.

16

Notes to Financial Statements (continued)

(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on investments in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized loss on investments in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.
(h)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs

17

Notes to Financial Statements (continued)

refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk-for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

•	Level 1 –	unadjusted quoted prices in active markets for identical investments;
•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES   

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.50%
Over $1 billion	.45%

For the fiscal year ended December 31, 2016, the effective management fee paid to Lord Abbett was at an annualized rate of .50% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract

18

Notes to Financial Statements (continued)

owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended			Year Ended
		12/31/2016			12/31/2015
Distributions paid from:
Ordinary income			$17,544,959			$  9,226,920
Net long-term capital gains			2,143,944			39,501,560
Total distributions paid			$19,688,903			$48,728,480

As of December 31, 2016, the components of accumulated gains on a tax-basis were as follows:

Undistributed ordinary income – net	$	4,812,150
Total undistributed earnings		4,812,150
Temporary differences		(212,408	)
Unrealized gains – net		84,052,504
Total accumulated gains – net	$	88,652,246

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	644,306,357
Gross unrealized gain		91,214,526
Gross unrealized loss		(7,162,022	)
Net unrealized security gain	$	84,052,504

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to wash sales.

19

Notes to Financial Statements (continued)

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Distributions in	Accumulated
Excess of Net	Net Realized
Investment Income	Loss
$(544,202)	$544,202

The permanent differences are attributable to the tax treatment of certain distributions.

5. PORTFOLIO SECURITIES TRANSACTIONS   

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases	Sales
$675,273,057	$780,771,296

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES   

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

		Gross Amounts	Net Amounts of
		Offset in the	Assets Presented
	Gross Amounts of	Statement of Assets	in the Statement of
Description	Recognized Assets	and Liabilities	Assets and Liabilities
Repurchase Agreement	$13,003,275	$     –	$13,003,275
Total	$13,003,275	$     –	$13,003,275

	Net Amounts
	of Assets	Amounts Not Offset in the
	Presented in	Statement of Assets and Liabilities
	the Statement		Cash	Securities
	of Assets and	Financial	Collateral	Collateral	Net
Counterparty	Liabilities	Instruments	Received(a)	Received(a)	Amount(b)
Fixed Income Clearing Corp.	$13,003,275	$          –	$          –	$(13,003,275)	$          –
Total	$13,003,275	$          –	$          –	$(13,003,275)	$          –

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

Notes to Financial Statements (continued)

7. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

8. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

9. LINE OF CREDIT   

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

10. INTERFUND LENDING PROGRAM   

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund participated as a lender in the Interfund Lending Program. The average amount loaned and interest rate were $13,565,965 and 0.725%, respectively. The Fund earned interest of $269, which is included in the Statement of Operations. There were no interfund loans outstanding as of December 31, 2016.

11. CUSTODIAN AND ACCOUNTING AGENT   

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

12. INVESTMENT RISKS   

The Fund is subject to the general risks and considerations associated with equity investing, as well as the particular risks associated with value stocks. The value of an investment will fluctuate in response to movements in the equity securities market in general and to the changing prospects of individual companies in which the Fund invests. Large-cap value stocks may perform differently than the market as a whole and other types of stocks, such as small company stocks and growth stocks. This is because different types of stocks tend to shift in and out of favor depending on market and economic conditions. The market may fail to recognize the intrinsic value of particular value stocks for a long time. In addition, if the Fund’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is wrong, the Fund could suffer losses or produce poor performance relative to other funds, even in a rising market.

Due to its investments in multinational companies, foreign companies and American Depositary Receipts, the Fund may experience increased market, liquidity, currency, political, information and other risks.

These factors can affect the Fund’s performance.

13. SUMMARY OF CAPITAL TRANSACTIONS   

Transactions in shares of capital stock were as follows:

		Year Ended				Year Ended
	December 31, 2016				December 31, 2015
Shares sold			565,181				762,180
Reinvestment of distributions			534,694				1,522,289
Shares reacquired			(4,015,682	)			(4,628,201	)
Decrease			(2,915,807	)			(2,343,732	)

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Growth and Income Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Growth and Income Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Growth and Income Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year and three-year periods and below the median of the performance peer group for the five-year and ten-year periods. The Board also

29

Approval of Advisory Contract (continued)

considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoint in the level of the management fee, adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible

30

Approval of Advisory Contract (concluded)

benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

For the fiscal year ended December 31, 2016, the Fund returned 1.23%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the Russell Midcap^® Growth Index,¹ which returned 7.33% over the same period.

Domestic equity markets (as represented by the S&P 500^® Index²) returned 11.96% over the past year. Despite this general move higher, there were significant bouts of volatility within U.S. stock markets, including their worst start to a calendar year on record.

Crude oil prices played a significant role in the increased market volatility, as Brent oil prices fluctuated sharply throughout the fiscal year. In December, the Organization of Petroleum Exporting Countries agreed to reduce oil production effective 2017. Furthermore, global markets were affected by the devaluation of China’s currency and weak economic data out of the region. The Chinese economy advanced at an annual rate of 6.7% in the third quarter of 2016, a slower pace than in recent years.

1

Geopolitical events also contributed to volatility in global markets. The United Kingdom’s referendum in June to leave the European Union (“Brexit”) was a surprise that caused a sell-off in global markets.

In contrast to the equity market volatility, the U.S. economy continued to expand during the trailing 12-month period. The Federal Reserve (Fed) raised target rates in for the second time in 12 months in December, from 0.25%–0.50% to 0.50%–0.75%. U.S. gross domestic product (GDP) grew at a 3.2% pace during the third quarter, a significant increase over the second quarter. The U.S. Bureau of Economic Analysis stated that during the third-quarter personal consumption and federal government spending increased, quarter over quarter. In addition to GDP growth, the U.S. unemployment rate remained relatively steady throughout the period, finishing at 4.6% in November.

The U.S. presidential election took an unexpected turn as Donald J. Trump was elected president, in contrast to indications from poll numbers before the election. Markets rallied on improved clarity in the U.S. political agenda, with the House and Senate also under Republican control.

During the period, stock selection in the information technology and consumer discretionary sectors were the largest detractors from the Fund’s performance relative to its benchmark. Within the information technology sector, the Fund’s holdings of LinkedIn Corp., a social media company focused on professional

networks, detracted most. Shares of LinkedIn plummeted as it issued lower revenue growth guidance for 2016 and began exiting Bizo, a business marketing firm it acquired in 2014. The Fund’s position in Alliance Data Systems, Inc., a provider of outsourced marketing solutions, also detracted from performance. Shares fell as the Canadian economy struggled; approximately 12% of Alliance Data Systems’ revenue is derived from Canada. In addition, its credit card services and Loyalty One business fell short of consensus estimates.

Within the consumer discretionary sector, the Fund’s holdings of Delphi Automotive PLC, a vehicle components manufacturer, detracted the most from relative performance. Shares of Delphi Automotive fell as it provided earnings per share and organic growth targets that were below consensus estimates.

During the period, security selection in the health care and materials sectors were the largest contributors to the Fund’s relative performance. Within the health care sector, the Fund’s holdings of Medivation, Inc., a biopharmaceutical company, contributed most. Shares of Medivation rose after Pfizer completed its acquisition of the company in September 2016. IDEXX Laboratories, a multinational corporation engaged in the development, manufacture, and distribution of products and services for the companion animal veterinary, livestock and poultry, water testing, and dairy markets, also contributed

2

to performance. Shares of IDEXX Laboratories increased as instrument placement metrics strengthened, specifically its Sedivue Dx analyzer.

Within the materials sector, the Fund’s holdings of Vulcan Materials Co., a producer of construction materials, contributed the most. Shares of Vulcan Materials moved higher as the company experienced volume growth across all of its

markets and benefited from expectations for a strong Department of Transportation budget.

The Fund’s portfolio is actively managed and therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹   The Russell Midcap^® Growth Index measures the performance of those Russell Midcap companies with higher price-to-book ratios and higher forecasted growth values.

²   The S&P 500^® Index is widely regarded as the standard for measuring large cap U.S. stock market performance and includes a representative sample of leading companies in leading industries.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense

waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer own the securities described above or may have otherwise changed their positions in the securities.

A Note about Risk: See Notes to Financial Statements for a discussion of investment risks. For a more detailed discussion of the risks associated with each Fund, please see the Fund’s prospectus.

Mutual funds are not insured by the FDIC, are not deposits or other obligations of, or guaranteed by, banks, and are subject to investment risks including possible loss of principal amount invested.

The Fund serves as an underlying investment vehicle for variable annuity contracts and variable life insurance policies.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in both the Russell Midcap^® Growth Index and the Russell Midcap^® Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. The line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During certain periods, expenses of the Fund have been waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value	Ending Account Value	Expenses Paid During Period†
	7/1/16	12/31/16	7/1/16 – 12/31/16
Class VC
Actual	$1,000.00	$1,007.20	$5.55
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,019.61	$5.58

^† Net expenses are equal to the Fund’s annualized expense ratio of 1.10%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION  

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (“the Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Growth Opportunities Portfolio (the “Fund”).

The Fund’s investment objective is capital appreciation. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.

16

Notes to Financial Statements (continued)

(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on investments in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized gain on investments in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.
(h)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of

17

Notes to Financial Statements (continued)

unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

• Level 1 – unadjusted quoted prices in active markets for identical investments;

• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and

• Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.80%
Next $1 billion	.75%
Next $1 billion	.70%
Over $3 billion	.65%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of .60% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

18

Notes to Financial Statements (continued)

Effective May 1, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses to an annual rate of 1.10%. This agreement may be terminated only upon the approval of the Board. Prior to May 1, 2016, Lord Abbett had contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net operating expenses to an annual rate of 1.20%

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended 12/31/2016			Year Ended 12/31/2015
Distributions paid from:
Ordinary income		$	–		$	2,224,813
Net long-term capital gains			736,893			7,531,254
Total distributions paid		$	736,893		$	9,756,067

As of December 31, 2016, the components of accumulated losses on a tax-basis were as follows:

Undistributed long-term capital gains	$	775,057
Total undistributed earnings		775,057
Temporary differences		(17,279	)
Unrealized losses – net		(1,079,662	)
Total accumulated losses – net	$	(321,884	)

19

Notes to Financial Statements (continued)

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	125,009,365
Gross unrealized gain		4,616,059
Gross unrealized loss		(5,695,721	)
Net unrealized security loss	$	(1,079,662	)

The difference between book-basis and tax basis unrealized gains (losses) is attributable to wash sales.

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Accumulated		Accumulated
Net Investment		Net Realized		Paid-in
Loss		Loss		Capital
	$265,510		$15,742		$(281,252	)

The permanent differences are attributable to the tax treatment of certain distributions received and net investment losses.

5. PORTFOLIO SECURITIES TRANSACTIONS  

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases	Sales
$196,319,320	$165,283,623

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

20

Notes to Financial Statements (continued)

Description	Gross Amounts of Recognized Assets		Gross Amounts Offset in the Statement of Assets and Liabilities		Net Amounts of Assets Presented in the Statement of Assets and Liabilities
Repurchase Agreement		$1,759,653	$	–	$	1,759,653
Total		$1,759,653	$	–	$	1,759,653

	Net Amounts
	of Assets		Amounts Not Offset in the
	Presented in		Statement of Assets and Liabilities
Counterparty	the Statement of Assets and Liabilities		Financial Instruments		Cash Collateral Received(a)		Securities Collateral Received(a)			Net Amount(b)
Fixed Income Clearing Corp.	$	1,759,653	$	–	$	–	$	(1,759,653	)	$	–
Total	$	1,759,653	$	–	$	–	$	(1,759,653	)	$	–

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

7. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

8. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

9. LINE OF CREDIT  

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

21

Notes to Financial Statements (concluded)

10. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

11. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

12. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with equity investing. The value of an investment will fluctuate in response to movements in the equity securities market in general, and to the changing prospects of individual companies in which the Fund invests. The Fund has particular risks associated with growth stocks. Growth companies may grow faster than other companies, which may result in more volatility in their stock prices. In addition, if the Fund’s assessment of a company’s potential for growth or market conditions is wrong, it could suffer losses or produce poor performance relative to other funds, even in a rising market. The Fund invests largely in mid-sized company stocks, which may be less able to weather economic shifts or other adverse developments than those of larger, more established companies.

Due to the Fund’s investment exposure to foreign companies and American Depositary Receipts, the Fund may experience increased market, liquidity, currency, political, information, and other risks.

These factors can affect the Fund’s performance.

13. SUMMARY OF CAPITAL TRANSACTIONS  

Transactions in shares of capital stock were as follows:

	Year Ended December 31, 2016		Year Ended December 31, 2015
Shares sold	12,040,758		7,558,407
Reinvestment of distributions	59,571		815,710
Shares reacquired	(9,493,978	)	(7,389,904	)

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Growth Opportunities Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Growth Opportunities Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Growth Opportunities Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the

29

Approval of Advisory Contract (continued)

median of the performance peer group for the three-year and ten-year periods, equal to the median of the performance peer group for the five-year period and below the median of the performance peer group for the one-year period. The Board also considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

30

Approval of Advisory Contract (concluded)

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

Dear Shareholders: We are pleased to provide you with this overview of the performance of Lord Abbett Series Fund — International Core Equity Portfolio for the fiscal year ended December 31, 2016.

Foster Director, President and Chief Executive Officer

For the fiscal year ended December 31, 2016, the Fund returned -1.74%, reflecting performance at the net asset value (NAV) of Class VC Shares, with all distributions reinvested, compared to its benchmark, the MSCI EAFE^® Index with Gross Dividends¹, which returned 1.51% over the same period.

Over the period, global equity markets experienced significant volatility, as a result of continued central bank stimulus, sharp moves in commodity prices, the United Kingdom’s Brexit vote, uncertainty around Chinese economic growth, and the

U.S. election. Overall, European markets (as measured by the EURO STOXX 50^®2) rose roughly 1.7% in U.S. dollars for the period, while Japan’s Nikkei 225³ rose 2.38%.

At the end of 2015, the Federal Reserve (Fed) raised interest rates, for the first time since the financial crisis, to a range between 0.25%–0.50%. At that time, Fed expectations were for 4 rate hikes in 2016. That did not materialize, but the Fed did raise rates again at the December 2016 Fed meeting, from a range of 0.25%–0.50% to a range of 0.50%–0.75%, and indicated that it was targeting three rate hikes in

1

2017. Similarly, other central banks continued their accommodative monetary policies, as the European Central Bank cut the deposit rate in the Eurozone from –0.2% to –0.3% in December 2015 and increased its existing monetary easing program to €80 billion per month in March 2016. In January 2016, the Bank of Japan introduced negative rates on excess reserves in an effort to stimulate economic growth and, at its September meeting, introduced “yield curve control” to regulate both short- and long-term rates. The Bank of Japan also committed itself to expand the monetary base until inflation—as measured by the Consumer Price Index—exceeds 2%.

By February of 2016, crude oil prices had fallen to under $27/bbl. By the end of the year, however, prices had recovered to above $50, helped by an OPEC agreement to cut 1.2mm barrels per day in production and a separate production cut deal with non-OPEC producers. Adding to the volatility during the year was the United Kingdom’s vote, to leave the European Union, which rattled global financial markets that had largely expected a “remain” vote. Following the vote, the British pound fell to a 30-year low and yields on U.K. bonds also fell to historical lows.

In November, Donald Trump won the U.S. presidential election, with Republicans seizing control of both the House of Representatives and the Senate, contributing to a strong U.S. market rally to finish 2016, which was fueled by

expectations for increased infrastructure and defense spending, broad tax reform, and decreased regulations. The Trump election drove the Japanese yen sharply lower, resulting in a double-digit rally in Japan’s Nikkei to close out the year. The Mexican peso also has suffered significantly since the election, as Trump repeatedly threatened to build a border wall with Mexico and took aim at multinational exporters and free-trade agreements. In Italy, a referendum on constitutional reforms was voted down, causing Prime Minister Matteo Renzi to submit his resignation. The Italian government also approved a €20 billion facility in December to provide stability to its banking sector after capital levels were criticized by the ECB.

During the period, the Fund’s underperformance relative to the benchmark was primarily driven by stock selection in the consumer discretionary and industrials sectors. Within the consumer discretionary sector, Berkeley Group Holdings plc, an English mixed-use property development company, detracted from relative performance. The company’s stock declined significantly after the United Kingdom’s Brexit vote, with a broad decline in the country’s biggest homebuilders. In addition, ITV plc, a United Kingdom-based media company, performed poorly over the period. The company suffered after the U.K.’s Brexit vote due to its significant operational exposure.

2

Within the industrials sector, Japan Airlines Co. Ltd., a Japan-based airline company, performed poorly over the period after company earnings decreased due to employee cost increases and decreased travel volume stemming from an increase in terrorist acts around the world.

Stock selection within the materials sector contributed to the Fund’s relative performance during the period. Within materials, shares of Fortescue Metals Group, an iron ore exploration, development, production, and processing company, rallied on the back of both higher iron ore prices and greater production. In addition, shares of South32 Ltd., an Australian metals and mining company, rose as the company was able to reduce

costs while its higher margin mining assets performed better than expected.

Stock selection within the utilities sector also contributed to the Fund’s relative performance during the period. Within the sector, shares of Snam S.p.A., an Italian natural-gas distribution network, performed well, as the company benefited from being viewed as a safety stock following volatility caused by the U.K.’s Brexit vote.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after

this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer own the securities described above or may have otherwise changed their positions in the securities. For more recent information about the Fund’s portfolio holdings, please visit www.lordabbett.com.

A Note about Risk: See Notes to Financial Statements for a discussion of investment risks. For a more detailed discussion of the risks associated with each Fund, please see the Fund’s prospectus.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the MSCI EAFE^® Index with Gross Dividends and the MSCI EAFE^® Index with Net Dividends, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. This line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During the period, expenses of the Fund were waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

¹ Performance for each unmanaged index does not reflect any fees or expenses. The performance of each index is not necessarily representative of the Fund’s performance. Performance for each index began on May 1, 2010.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

6

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value	Ending Account Value	Expenses Paid During Period†
	7/1/16	12/31/16	7/1/16 - 12/31/16
Class VC
Actual	$1,000.00	$1,045.60	$4.47
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,020.76	$4.42

^† Net expenses are equal to the Fund’s annualized expense ratio of 0.87%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION  

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (“the Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers International Core Equity Portfolio (the “Fund”).

The Fund’s investment objective is to seek long-term capital appreciation. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a) Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.

Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.

Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.

Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.

20

Notes to Financial Statements (continued)

(b) Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.

(c) Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.

(d) Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.

The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

(e) Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.

(f) Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on translation of assets and liabilities denominated in foreign currencies in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized loss on foreign currency related transactions in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.

The Fund uses foreign currency exchange contracts to facilitate transactions in foreign-denominated securities. Losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts’ terms.

(g) Forward Foreign Currency Exchange Contracts–The Fund may enter into forward foreign currency exchange contracts in order to reduce their exposure to changes in foreign currency exchange rates on their foreign portfolio holdings, or gain or reduce exposure to foreign currency solely for investment purposes. A forward foreign currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated rate. The contracts are valued daily at forward exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on translation of assets and liabilities denominated in foreign currencies in the Fund’s Statement of Operations. The gain (loss) arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing of such contracts is included in Net realized loss on foreign currency related transactions in the Fund’s Statement of Operations.

21

Notes to Financial Statements (continued)

(h) Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.

(i) Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

•	Level 1 –	unadjusted quoted prices in active markets for identical investments;
•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.75%
Next $1 billion	.70%
Over $2 billion	.65%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of 0.23% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses, excluding any acquired fund fees and expenses, to an annual rate of .87%. This agreement may be terminated only upon the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to ..25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

23

Notes to Financial Statements (continued)

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended 12/31/2016	Year Ended 12/31/2015
Distributions paid from:
Ordinary income	$1,555,460	$911,239
Return of capital	–	31,072
Total distributions paid	$1,555,460	$942,311

As of December 31, 2016, the components of accumulated losses on a tax-basis were as follows:

Capital loss carryforwards*	$	(8,417,878	)
Temporary differences		(13,012	)
Unrealized gains – net		924,191
Total accumulated losses – net	$	(7,506,699	)

* The capital losses will carry forward indefinitely.

At the Fund’s election, certain losses incurred within the taxable year (Qualified Late-Year Losses) are deemed to arise on the first business day of the Fund’s next taxable year. The Fund incurred and will elect to defer late-year ordinary losses of $8,472 during fiscal 2016.

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	57,989,121
Gross unrealized gain		2,765,823
Gross unrealized loss		(1,836,905	)
Net unrealized security gain	$	928,918

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to the tax treatment of certain foreign securities and wash sales.

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Distributions in Excess of Net Investment Income	Accumulated Net Realized Loss		Paid-in Capital
$112,006	$(95,405	)	$(16,601	)

The permanent differences are attributable to the tax treatment of foreign currency transactions, certain expenses, certain distributions, and certain foreign securities.

5. PORTFOLIO SECURITIES TRANSACTIONS  

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases	Sales
$110,408,183	$108,278,226

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

24

Notes to Financial Statements (continued)

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

Description	Gross Amounts of Recognized Assets	Gross Amounts Offset in the Statement of Assets and Liabilities		Net Amounts of Assets Presented in the Statement of Assets and Liabilities
Repurchase Agreement	$1,103,554	$	–	$1,103,554
Total	$1,103,554	$	–	$1,103,554

	Net Amounts of Assets Presented in	Amounts Not Offset in the Statement of Assets and Liabilities
Counterparty	the Statement of Assets and Liabilities	Financial Instruments		Cash Collateral Received(a)		Securities Collateral Received(a)	Net Amount(b)
Fixed Income Clearing Corp.	$1,103,554	$	–	$	–	$(1,103,554)	$	–
Total	$1,103,554	$	–	$	–	$(1,103,554)	$	–

^(a) Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.

^(b) Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

7. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

8. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

25

Notes to Financial Statements (continued)

9. LINE OF CREDIT  

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

10. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

11. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

12. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with equity investing. The value of an investment will fluctuate in response to movements in the equity securities markets in general and to the changing prospects of individual companies in which the Fund invests.

Large company value stocks, in which the Fund invests, may perform differently than the market as a whole and other types of stocks, such as small company stocks and growth stocks.

The Fund is subject to the risks of investing in foreign securities and derivatives. Foreign securities may pose greater risks than domestic securities, including greater price fluctuations and higher transaction costs. Foreign investments also may be affected by changes in currency rates or currency controls. These risks are generally greater for securities issued by companies in emerging market countries.

The Fund is also subject to the risks associated with derivatives, which may be different from and greater than the risks associated with investing directly in securities and other investments.

These factors can affect the Fund’s performance.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of International Core Equity Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the International Core Equity Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of International Core Equity Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year period and below the median of the performance peer group for the three-year and five-year periods. The Board also considered Lord

34

Approval of Advisory Contract (continued)

Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible

35

Approval of Advisory Contract (concluded)

benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

Lord Abbett Series Fund — International Opportunities Portfolio
Annual Report

For the fiscal year ended December 31, 2016

  From left to right: James L.L. Tullis, Chairman of the Lord Abbett Funds and Daria L. Foster Director, President, and Chief Executive Officer of the Lord Abbett Funds. Dear Shareholders: We are pleased to provide you with this overview of the performance of Lord Abbett Series Fund — International Opportunities Portfolio for the fiscal year ended December 31, 2016. On this page and the following pages, we discuss the major factors that influenced fiscal year performance. For additional information about the Fund, please visit our website at www.lordabbett.com, where you also can access the quarterly commentaries that provide updates on the Fund’s performance and other portfolio related updates. Thank you for investing in Lord Abbett mutual funds. We value the trust that you place in us and look forward to serving your investment needs in the years to come.   Best regards,     Daria L. Foster Director, President and Chief Executive Officer

For the fiscal year ended December 31, 2016, the Fund returned -4.28%, reflecting performance at the net asset value (NAV) of Class VC Shares, with all distributions reinvested, compared to its benchmark, the S&P Developed Ex US SmallCap^® Index¹, which returned 3.78% over the same period.

Over the period, global equity markets experienced significant volatility, as a result of continued central bank stimulus, sharp moves in commodity prices, the United Kingdom’s Brexit vote, uncertainty around Chinese economic growth, and the U.S. election. Overall, European markets (as measured by the EURO STOXX 50^®2) rose

roughly 1.7% in U.S. dollars for the period, while Japan’s Nikkei 225³ rose 2.38%.

At the end of 2015, the Federal Reserve (Fed) raised interest rates, for the first time since the financial crisis, to a range between 0.25% - 0.50%. At that time, Fed expectations were for 4 rate hikes in 2016. That did not materialize, but the Fed did raise rates again at the December 2016 Fed meeting, to a range of 0.50%-0.75%, and indicated that it was targeting three rate hikes in 2017. Similarly, other central banks continued their accommodative monetary policies, as the European Central Bank cut the deposit rate in the Eurozone from -0.2% to -0.3% in December 2015 and increased

1

its existing monetary easing program to €80 billion per month in March 2016. In January 2016, the Bank of Japan introduced negative rates on excess reserves in an effort to stimulate economic growth and, at its September meeting, introduced “yield curve control” to regulate both short- and long-term rates. The Bank of Japan also committed itself to expand the monetary base until inflation–as measured by the Consumer Price Index - exceeds 2%.

By February of 2016, crude oil prices had fallen to under $27/bbl. By the end of the year, however, prices had recovered to above $50, helped by an OPEC agreement to cut 1.2mm barrels per day in production and a separate production cut deal with non-OPEC producers. Adding to the volatility during the year was the United Kingdom’s vote, to leave the European Union, which rattled global financial markets that had largely expected a “remain” vote. Following the vote, the British pound fell to a 30-year low and yields on U.K. bonds also fell to historical lows.

In November, Donald Trump won the U.S. presidential election, with Republicans seizing control of both the House of Representatives and the Senate, contributing to a strong U.S. market rally to finish 2016, which was fueled by expectations for increased infrastructure and defense spending, broad tax reform, and decreased regulations. The Trump election drove the Japanese yen sharply lower, resulting in a double-digit rally in Japan’s Nikkei to close out the year. The Mexican peso also has suffered significantly since the election, as Trump repeatedly threatened to build a border wall with Mexico and took aim at multinational exporters and free-trade

agreements. In Italy, a referendum on constitutional reforms was voted down, causing Prime Minister Matteo Renzi to submit his resignation. The Italian government also approved a €20 billion facility in December to provide stability to its banking sector after capital levels were criticized by the ECB.

Stock selection, most notably in the materials and consumer discretionary sectors, was the primary driver of relative underperformance during the period. Within materials, shares of Essentra plc, a United Kingdom-based manufacturer and distributor of tobacco supplies, declined after missing earnings for the first half of 2016 and experiencing a decline in revenue. In addition, Hill & Smith Holdings PLC, a United Kingdom-based manufacturer and supplier of infrastructure products and galvanizing services, detracted from performance as shares reversed from strong gains earlier in the year.

Within the consumer discretionary sector, shares of DFS Furniture PLC, a United Kingdom-based furniture and fixture manufacturer, declined after the U.K.’s Brexit vote in June and amid concerns for the housing market.

Conversely, stock selection in the information technology and consumer staples sectors contributed to relative performance. Within the information technology sector, shares of SUMCO Corp., a Japanese silicon manufacturer, rose as the company benefited from the yen’s weakening and the higher value of the company’s exports. In addition, shares of Hitachi High-Tech Corp., an electronic components manufacturer, also rose, as the company benefited from continued

2

growth in the science and medical systems segment and as the company’s exports benefited from a weaker yen.

Within the consumer staples sector, Treasury Wine Est. Ltd, an operator of vineyards and wineries, contributed to the Fund’s performance. The company’s stock rose as the company continued to focus on

growing margins with ambitious expansion initiatives.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹  The S&P Developed Ex-U.S. SmallCap^® Index captures the bottom 15% of companies domiciled in the developed markets (excluding the United States) within the S&P Global BMI with a float-adjusted market capitalization of at least US$100 million and a value traded of at least US$50 million for the past 12 months at the time of the annual reconstitution.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be

higher or lower than the performance quoted.

You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer own the securities described above or may have otherwise changed their positions in the securities.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the S&P Developed Ex-U.S. SmallCap Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. This line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During certain periods, expenses of the Fund have been waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value	Ending Account Value	Expenses Paid During Period†
	7/1/16	12/31/16	7/1/16 - 12/31/16
Class VC
Actual	$1,000.00	$1,021.90	$6.10
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,019.10	$6.09

Notes to Financial Statements

1. ORGANIZATION  

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers International Opportunities Portfolio (the “Fund”).

The Fund’s investment objective is long-term capital appreciation. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.

18

Notes to Financial Statements (continued)

(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on translation of assets and liabilities denominated in foreign currencies in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized loss on foreign currency related transactions in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
	The Fund uses foreign currency exchange contracts to facilitate transactions in foreign-denominated securities. Losses from these transactions may arise from changes in the value of the foreign currency or if the counterparties do not perform under the contracts’ terms.
(g)	Forward Foreign Currency Exchange Contracts–The Fund may enter into forward foreign currency exchange contracts in order to reduce exposure to changes in foreign currency exchange rates on foreign portfolio holdings or gain or reduce exposure to foreign currency solely for investment purposes. A forward foreign currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated rate. The contracts are valued daily at forward exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on translation of assets and liabilities denominated in foreign currencies in the Fund’s Statement of Operations. The gain (loss) arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing of such contracts is included in Net realized loss on foreign currency related transactions in the Fund’s Statement of Operations.

19

Notes to Financial Statements (continued)

(h)

Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.

(i)

Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk – for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

•	Level 1 –	unadjusted quoted prices in active markets for identical investments;
•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.75%
Next $1 billion	.70%
Over $2 billion	.65%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of .39% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses to an annual rate of 1.20%. This agreement may be terminated only upon the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to ..25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

21

Notes to Financial Statements (continued)

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended 12/31/2016		Year Ended 12/31/2015
Distributions paid from:
Ordinary income	$	435,134	$	1,143,859
Net long-term capital gains		–		3,386,299
Total distributions paid	$	435,134	$	4,530,158

As of December 31, 2016, the components of accumulated losses on a tax-basis were as follows:

Undistributed ordinary income – net	$	29,201
Total undistributed earnings		29,201
Capital loss carryforwards*		(1,785,796	)
Temporary differences		(8,166	)
Unrealized gains – net		1,217,950
Total accumulated losses – net	$	(546,811	)

* The capital losses will carry forward indefinitely.

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	41,544,984
Gross unrealized gain		3,693,232
Gross unrealized loss		(2,474,247	)
Net unrealized security gain	$	1,218,985

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to the tax treatment of certain foreign securities and wash sales.

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Distributions in Excess of Net Investment Income		Accumulated Net Realized Loss
	$107,107		$(107,107	)

The permanent differences are attributable to the tax treatment of certain foreign securities, certain expenses, and foreign currency transactions.

5. PORTFOLIO SECURITIES TRANSACTIONS  

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases		Sales
	$39,112,621		$46,543,621

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

Description	Gross Amounts of Recognized Assets		Gross Amounts Offset in the Statement of Assets and Liabilities		Net Amounts of Assets Presented in the Statement of Assets and Liabilities
Repurchase Agreement	$	221,368	$	–	$	221,368
Total	$	221,368	$	–	$	221,368

	Net Amounts of Assets Presented in		Amounts Not Offset in the Statement of Assets and Liabilities
Counterparty	the Statement of Assets and Liabilities		Financial Instruments		Cash Collateral Received(a)		Securities Collateral Received(a)			Net Amount(b)
Fixed Income Clearing Corp.	$	221,368	$	–	$	–	$	(221,368	)	$	–
Total	$	221,368	$	–	$	–	$	(221,368	)	$	–

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

7. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

8. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

23

Notes to Financial Statements (continued)

9. LINE OF CREDIT  

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

10. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

11. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

12. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with equity investing. These include the risks of investing in equity markets in foreign countries, the risk of investing in derivatives, liquidity risk, and the risks from leverage. The value of an investment will fluctuate in response to movements in the stock market in general, and to the changing prospects of individual companies in which the Fund invests. The Fund is subject to the risks of investing in foreign securities and in the securities of small companies. Foreign securities may pose greater risks than domestic securities, including greater price fluctuations and higher transaction costs. Foreign investments also may be affected by changes in currency rates or currency controls. These risks are generally greater for securities issued by companies in emerging market countries. Investing in small companies generally involves greater risks than investing in the stocks of larger companies, including more volatility and less liquidity.

The Fund is also subject to the risks associated with derivatives, which may be different from and greater than the risks associated with investing directly in securities and other instruments.

These factors can affect the Fund’s performance.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of International Opportunities Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the International Opportunities Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of International Opportunities Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of the Fund’s benchmark; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and the Fund’s benchmark as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the three-year and five-year periods and below the median of the performance peer group for the one-year and ten-year periods. The Board also considered Lord

32

Approval of Advisory Contract (continued)

Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord

33

Approval of Advisory Contract (concluded)

Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

Director, President and Chief Executive Officer

For the fiscal year ended December 31, 2016, the Fund returned 16.39%, reflecting performance at the net asset value (NAV) of Class A shares, with all distributions reinvested, compared to its benchmark, the Russell Midcap^® Value Index,¹ which returned 20.00% over the same period.

Domestic equity markets (as represented by the S&P 500^® Index²) returned 11.96% over the past year. Despite this general move higher, there were significant bouts of volatility within U.S. stock markets, including their worst start to a calendar year on record.

Crude oil prices played a significant role in the increased market volatility, as Brent oil prices fluctuated sharply throughout the fiscal year. In December, the Organization of Petroleum Exporting Countries agreed to reduce oil production effective 2017. Furthermore, global markets were affected by the devaluation of China’s currency and weak economic data out of the region. The Chinese economy advanced at an annual rate of 6.7% in the third quarter of 2016, a slower pace than in recent years.

1

Geopolitical events also contributed to volatility in global markets. The United Kingdom’s referendum in June to leave the European Union (“Brexit”) was a surprise that caused a sell-off in global markets.

In contrast to the equity market volatility, the U.S. economy continued to expand during the trailing 12-month period. The Federal Reserve (Fed) raised target rates for the second time in 12 months in December, from 0.25%–0.50% to 0.50%–0.75%. U.S. gross domestic product (GDP) grew at a 3.2% pace during the third quarter, a significant increase over the second quarter. The U.S. Bureau of Economic Analysis stated that during the third-quarter personal consumption and federal government spending increased, quarter over quarter. In addition to GDP growth, the U.S. unemployment rate remained relatively steady throughout the period, finishing at 4.6% in November.

The U.S. presidential election took an unexpected turn as Donald J. Trump was elected president, in contrast to indications from poll numbers before the election. Markets rallied on improved clarity in the U.S. political agenda, with the House and Senate also under Republican control.

During the period, stock selection and an underweight in the industrials sector were the largest detractors from the Fund’s performance relative to its benchmark. Within the industrials sector, the Fund’s holdings of Parker Hannifin Corp., a manufacturer of motion-control and fluid

systems and components within multiple industries, detracted most. Parker Hannifin fell as organic growth expectations remained flat, specifically its business segments in North America. The Fund’s position in Stanley Works, a provider of appliances and tools for various industrial applications, also detracted from performance. Shares fell as the company faced macro headwinds from declining industry sales and low growth in emerging market regions.

Stock selection in the information technology sector also detracted from the Fund’s performance. The Fund’s holdings of Verifone Systems, Inc., an electronic payment solutions company, detracted most. Shares of Verifone Systems, Inc. fell as it missed second quarter earnings estimates as macro challenges outside the United States created headwinds for future revenue growth and profitability.

During the period, security selection and an overweight in the energy sector were the largest contributors to the Fund’s relative performance. Within the energy sector, the Fund’s holdings of Patterson-UTI Energy, Inc., a domestic land-based drilling rigs and pressure pumping equipment operator, and Cimarex Energy Co., an independent oil and gas exploration and production company, both contributed to performance. Patterson and Cimarex benefitted as U.S. rig counts and oil prices increased throughout the calendar year.

Stock selection in the consumer discretionary sector also contributed to the

2

Fund’s performance. The Fund’s holding of Whirlpool Corp., a marketer and manufacturer of home appliances, contributed most. Whirlpool shares gained as the firm expected to implement cost-cutting and productivity measures that were expected to improve earnings growth despite a declining industry growth.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹  The Russell Midcap^® Value Index measures the performance of those Russell Midcap companies with lower price-to-book ratios and lower forecasted growth values. The stocks are also members of the Russell 1000^® Value index.

²  The S&P 500^® Index is widely regarded as the standard for measuring large cap U.S. stock market performance and includes a representative sample of leading companies in leading industries.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted.

You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in both the Russell Midcap^® Value Index and the S&P MidCap 400^® Value Index assuming reinvestment of all dividends and distributions. the Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. This line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Past performance is no guarantee of future results.

 

Average Annual Total Returns for the

Periods Ended December 31, 2016

Class VC	16.39%	13.27%	5.66%

¹  Performance for each unmanaged index does not reflect any fees or expenses. The performance of each index is not necessarily representative of the Fund’s performance.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning	Ending	Expenses
	Account	Account	Paid During
	Value	Value	Period(a)
			7/1/16 -
	7/1/16	12/31/16	12/31/16
Class VC
Actual	$1,000.00	$1,102.40	$6.24
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,019.20	$5.99

^(a) Net expenses are equal to the Fund’s annualized expense ratio of 1.18%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION  

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (“the Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Mid Cap Stock Portfolio (the “Fund”).

The Fund’s investment objective is to seek capital appreciation through investments, primarily in equity securities, which are believed to be undervalued in the marketplace. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.

16

Notes to Financial Statements (continued)

(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on investments in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized gain on investments in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.
(h)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer

17

Notes to Financial Statements (continued)

broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

•	Level 1 –	unadjusted quoted prices in active markets for identical investments;
•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.75%
Next $1 billion	.70%
Over $2 billion	.65%

For the fiscal year ended December 31, 2016, the effective management was at an annualized rate of .75% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the

18

Notes to Financial Statements (continued)

insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended 12/31/2016		Year Ended 12/31/2015
Distributions paid from:
Ordinary income	$	1,708,602	$	2,135,083
Net long-term capital gains		19,456,583		21,990,439
Total distributions paid	$	21,165,185	$	24,125,522

As of December 31, 2016, the components of accumulated gains on a tax-basis were as follows:

Undistributed ordinary income – net	$	198,039
Undistributed long-term capital gains		6,479,470
Total undistributed earnings		6,677,509
Temporary differences		(107,369	)
Unrealized gains – net		39,520,337
Total accumulated gains – net	$	46,090,477

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	317,356,045
Gross unrealized gain		46,515,719
Gross unrealized loss		(6,995,382	)
Net unrealized security gain	$	39,520,337

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to wash sales.

19

Notes to Financial Statements (continued)

5. PORTFOLIO SECURITIES TRANSACTIONS  

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases		Sales
	$227,469,927		$266,251,600

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

Description	Gross Amounts of Recognized Assets		Gross Amounts Offset in the Statement of Assets and Liabilities		Net Amounts of Assets Presented in the Statement of Assets and Liabilities
Repurchase Agreement	$	3,082,595	$	–	$	3,082,595
Total	$	3,082,595	$	–	$	3,082,595

	Net Amounts
	of Assets		Amounts Not Offset in the
	Presented in		Statement of Assets and Liabilities
Counterparty	the Statement of Assets and Liabilities		Financial Instruments		Cash Collateral Received(a)		Securities Collateral Received(a)			Net Amount(b)
Fixed Income Clearing Corp.	$	3,082,595	$	–	$	–	$	(3,082,595	)	$	–
Total	$	3,082,595	$	–	$	–	$	(3,082,595	)	$	–

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

7. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’

20

Notes to Financial Statements (continued)

fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

8. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

9. LINE OF CREDIT  

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

10. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

11. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

12. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with equity investing, as well as the particular risks associated with value and mid-sized company stocks. The value of an investment will fluctuate in response to movements in the equity securities market in general and to the changing prospects of individual companies in which the Fund invests. The market may fail to recognize for a long time the intrinsic value of particular value stocks the Fund may hold. The mid-sized company stocks in which the Fund invests may be less able to weather economic shifts or other adverse developments than those of larger, more established companies. In addition, if the Fund’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is wrong, the Fund could suffer losses or produce poor performance relative to other funds, even in a rising market.

21

Notes to Financial Statements (concluded)

Due to the Fund’s investment exposure to foreign companies and American Depositary Receipts, the Fund may experience increased market, liquidity, currency, political, information, and other risks.

These factors can affect the Fund’s performance.

13. SUMMARY OF CAPITAL TRANSACTIONS  

Transactions in shares of capital stock were as follows:

	Year Ended December 31, 2016		Year Ended December 31, 2015
Shares sold	972,000		783,314

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Mid Cap Stock Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Mid Cap Stock Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Mid Cap Stock Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the three-year period and below the median of the performance peer group for the one-year, five-year and ten-year periods. The Board also considered

29

Approval of Advisory Contract (continued)

Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was slightly above the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that

30

Approval of Advisory Contract (concluded)

the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

Lord Abbett Series Fund — Short Duration Income Portfolio Annual Report

For the fiscal year ended December 31, 2016

  From left to right: James L.L. Tullis, Chairman of the Lord Abbett Funds and Daria L. Foster Director, President, and Chief Executive Officer of the Lord Abbett Funds. Dear Shareholders: We are pleased to provide you with this overview of the performance of Lord Abbett Series Fund — Short Duration Income Portfolio for the fiscal year ended December 31, 2016. On this page and the following pages, we discuss the major factors that influenced fiscal year performance. For additional information about the Fund, please visit our website at www.lordabbett.com, where you also can access the quarterly commentaries that provide updates on the Fund’s performance and other portfolio related updates. Thank you for investing in Lord Abbett mutual funds. We value the trust that you place in us and look forward to serving your investment needs in the years to come.   Best regards,     Daria L. Foster Director, President and Chief Executive Officer

For the fiscal year ended December 31, 2016, the Fund returned 3.47%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the BofA Merrill Lynch 1-3 year U.S. Corporate Credit Index,¹ which returned 2.39% over the same period.

Yields on longer-dated Treasury bonds were relatively flat, rising only slightly over the 12-month period ended December 31, 2016, while the yield on shorter-dated two-year Treasury notes increased 0.18%

over the same period, leading to a slight flattening of the Treasury yield curve. Corporate credit spreads narrowed over the 12-month period, particularly within lower-rated, investment grade debt. Consumer prices rose at a moderate pace, with the Consumer Price Index (CPI) rising 2.1% over the 12-month period ended December 31, 2016. Meanwhile, the employment picture continued to improve as the unemployment rate remained steady at 4.7%, with 156,000 jobs added in December 2016; employment growth has

1

averaged 165,000 per month, over the last three months. This compares with an unemployment rate of 5.0% a year earlier and a recent high of 10.0% in October 2009. In December, the U.S. Federal Reserve (Fed) raised its target for short-term interest rates 0.25%, to a range of 0.50% - 0.75%, as economic data continued to suggest a strengthening domestic economy.

Consistent with the Fund’s strategic design, the Fund maintained exposures to a variety of bond market sectors, in addition to the investment grade corporate bonds represented in the benchmark. This design allows for the flexibility to take advantage of relative value opportunities across sectors, and these weightings were important factors affecting performance. The primary factors contributing to the Fund’s relative performance over the period were allocations to high yield corporate bonds and commercial mortgage-backed securities (CMBS). High

¹ The BofA Merrill Lynch 1-3 Year U.S. Corporate Credit Index is an unmanaged index comprised of U.S. dollar-denominated investment grade corporate debt securities publicly issued in the U.S. domestic market with between one and three years remaining to final maturity.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that

yield bonds outperformed higher-rated securities as spreads tightened, contributing to the relative performance of the Fund. Additionally, the Fund maintained out-of-benchmark exposure to securitized sectors, including commercial mortgage-backed securities, which aided absolute performance, as these sectors outperformed investment grade corporate bonds during the 12-month period.

The Fund’s underweight to investment grade corporates detracted from performance during the 12-month period. However, security selection was positive as the Fund remained overweight ‘BBB’ rated securities, which outperformed higher-rated securities.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

shares, on any given day or when redeemed, may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer

own the securities described above or may have otherwise changed their positions in the securities. For more recent information about the Fund’s portfolio holdings, please visit www.lordabbett.com.

The Fund serves as an underlying investment vehicle for variable annuity contracts and variable life insurance policies.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the BofA Merrill Lynch 1-3 Year U.S. Corporate Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. This line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During the period, expenses of the Fund were waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

Average Annual Total Returns for the Periods Ended December 31, 2016
	1 Year	Life of Class
Class VC2	3.47%	1.56%

¹  Performance for the unmanaged index does not reflect any fees or expenses. The performance of the index is not necessarily representative of the Fund’s performance. Performance for the index began on April 14, 2014.

²  The Class VC shares commenced operations on April 4, 2014. Performance for the Class began on April 14, 2014.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning Account Value	Ending Account Value	Expenses Paid During Period†
			7/1/16 -
	7/1/16	12/31/16	12/31/16
Class VC
Actual	$1,000.00	$1,007.50	$4.04
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,021.11	$4.06

^† Net expenses are equal to the Fund’s annualized expense ratio of 0.80%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION 

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Short Duration Income Portfolio (the “Fund”).

The Fund’s investment objective is to seek a high level of income consistent with preservation of capital. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES 

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices. Fixed income securities are valued based on evaluated prices supplied by independent pricing services, which reflect broker/dealer supplied valuations and the independent pricing services’ own electronic data processing techniques. Exchange traded options and futures contracts are valued at the last sale price in the market where they are principally traded. If no sale has occurred, the mean between the most recently quoted bid and asked prices is used. Floating rate loans are valued at the average of bid and ask quotations obtained from dealers in loans on the basis of prices supplied by independent pricing services. Forward foreign currency exchange contracts are valued using daily forward exchange rates.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book

Notes to Financial Statements (continued)

	values, yield curves, broker quotes, observable trading activity, option adjusted spread models and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.
(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remain open for the fiscal years ended December 31, 2014 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending on jurisdiction
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets. Offering costs incurred by the Fund are amortized over a twelve month period beginning at the commencement of operations and are included in the Fund’s Statement of Operations.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on futures contracts and translation of assets and liabilities denominated in foreign currencies on the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions, if any, are included in Net realized loss on futures contracts and foreign currency related transactions on the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Forward Foreign Currency Exchange Contracts–The Fund may enter into forward foreign currency exchange contracts in order to reduce exposure to changes in foreign currency exchange rates on foreign portfolio holdings, or gain or reduce exposure to foreign currency

49

Notes to Financial Statements (continued)

	solely for investment purposes. A forward foreign currency exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated rate. The contracts are valued daily at forward exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on futures contracts and translation of assets and liabilities denominated in foreign currencies in the Fund’s Statement of Operations. The gain (loss) arising from the difference between the U.S. dollar cost of the original contract and the value of the foreign currency in U.S. dollars upon closing of such contracts is included in Net realized gain on futures contracts and foreign currency related transactions in the Fund’s Statement of Operations.
(h)	Futures Contracts–The Fund may purchase and sell futures contracts to enhance returns, to attempt to economically hedge some of its investment risk, or as a substitute position in lieu of holding the underlying asset on which the instrument is based. At the time of entering into a futures transaction, an investor is required to deposit and maintain a specified amount of cash or eligible securities called “initial margin.” Subsequent payments made or received by the Fund called “variation margin” are made on a daily basis as the market price of the futures contract fluctuates. The Fund will record an unrealized gain (loss) based on the amount of variation margin. When a contract is closed, a realized gain (loss) is recorded equal to the difference between the opening and closing value of the contract.
(i)	When-Issued, Forward Transactions or To-Be-Announced (“TBA”) Transactions–The Fund may purchase portfolio securities on a when-issued or forward basis. When-issued, forward transactions or TBA transactions involve a commitment by a fund to purchase securities, with payment and delivery (“settlement”) to take place in the future, in order to secure what is considered to be an advantageous price or yield at the time of entering into the transaction. During the period between purchase and settlement, the fair value of the securities will fluctuate and assets consisting of cash and/or marketable securities (normally short-term U.S. Government or U.S. Government sponsored enterprise securities) marked to market daily in an amount sufficient to make payment at settlement will be segregated at the Fund’s custodian in order to pay for the commitment. At the time the Fund makes the commitment to purchase a security on a when-issued basis, it will record the transaction and reflect the liability for the purchase and fair value of the security in determining its net asset value (“NAV”). The Fund, generally, has the ability to close out a purchase obligation on or before the settlement date rather than take delivery of the security. Under no circumstances will settlement for such securities take place more than 120 days after the purchase date.
(j)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.
(k)	Floating Rate Loans–The Fund may invest in floating rate loans, which usually take the form of loan participations and assignments. Loan participations and assignments are agreements

50

Notes to Financial Statements (continued)

	to make money available to U.S. or foreign corporations, partnerships or other business entities (the “Borrower”) in a specified amount, at a specified rate and within a specified time. A loan is typically originated, negotiated and structured by a U.S. or foreign bank, insurance company or other financial institution (the “Agent”) for a group of loan investors (“Loan Investors”). The Agent typically administers and enforces the loan on behalf of the other Loan Investors in the syndicate and may hold any collateral on behalf of the Loan Investors. Such loan participations and assignments are typically senior, secured and collateralized in nature. The Fund records an investment when the Borrower withdraws money and records interest as earned. These loans pay interest at rates which are periodically reset by reference to a base lending rate plus a spread. These base lending rates are generally the prime rate offered by a designated U.S. bank or London InterBank Offered Rate (“LIBOR”).
	The loans in which the Fund invests may be subject to some restrictions on resale. For example, the Fund may be contractually obligated to receive approval from the Agent and/or Borrower prior to the sale of these investments. The Fund generally has no right to enforce compliance with the terms of the loan agreement with the Borrower. As a result, the Fund assumes the credit risk of the Borrower, the selling participant and any other persons interpositioned between the Fund and the Borrower (“Intermediate Participants”). In the event that the Borrower, selling participant or Intermediate Participants become insolvent or enter into bankruptcy, the Fund may incur certain costs and delays in realizing payment or may suffer a loss of principal and/or interest.
	Unfunded commitments represent the remaining obligation of the Fund to the Borrower. At any point in time, up to the maturity date of the issue, the Borrower may demand the unfunded portion. Until demanded by the Borrower, unfunded commitments are not recognized as an asset on the Statement of Assets and Liabilities. Unrealized appreciation/depreciation on unfunded commitments presented on the Statement of Assets and Liabilities represents mark to market of the unfunded portion of the Fund’s floating rate notes. As of December 31, 2016, the Fund did not have unfunded loan commitments.
(l)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk – for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

• Level 1 – unadjusted quoted prices in active markets for identical investments;

51

Notes to Financial Statements (continued)

•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments and other financial instruments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES 

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.35%
Next $1 billion	.30%
Over $2 billion	.25%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of 0.10% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net operating expenses to an annual rate of .80%. This agreement may be terminated only upon the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS 

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and December 31, 2015 was as follows:

	Year Ended 12/31/2016		Year Ended 12/31/2015
Distributions paid from:
Ordinary income	$	1,192,100	$	510,107
Return of capital		–		9,628
Total distributions paid	$	1,192,100	$	519,735

As of December 31, 2016, the components of accumulated losses on a tax-basis were as follows:

Undistributed ordinary income – net	$	3,150
Total undistributed earnings		3,150
Capital loss carryforwards*		(442,173	)
Temporary differences		(1,016	)
Unrealized losses – net		(612,093	)
Total accumulated losses – net	$	(1,052,132	)

* The capital losses will carryforward indefinitely

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	47,701,244
Gross unrealized gain		209,894
Gross unrealized loss		(821,982	)
Net unrealized security loss	$	(612,088	)

The difference between book-basis and tax-basis unrealized gains (losses) is due to tax treatment of premium amortization, certain securities and wash sales.

53

Notes to Financial Statements (continued)

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Undistributed Net Investment Income		Accumulated Net Realized Loss			Paid-in Capital
	$529,464		$(529,348	)		$(116	)

The permanent differences are attributable to the tax treatment of foreign currency transactions, premium amortization, certain distributions, certain securities, and principal paydown gains and losses.

5. PORTFOLIO SECURITIES TRANSACTIONS   

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

U.S.	Non-U.S.	U.S.	Non-U.S.
Government	Government	Government	Government
Purchases*	Purchases	Sales*	Sales
$4,357,172	$41,824,997	$4,118,233	$15,606,992

* Includes U.S. Government sponsored enterprises securities.

The Fund is permitted to purchase and sell securities (“cross-trade”) from and to other Lord Abbett funds or client accounts pursuant to procedures approved by the Board in compliance with Rule 17a-7 under the Act (the “Rule”). Each cross-trade is executed at a fair market price in compliance with provisions of the Rule. For the period ended December 31, 2016, the Fund engaged in cross-trades purchases of $572,967 and sales of $379,569, which resulted in net realized loss of $(4,833).

6. DISCLOSURES ABOUT DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES   

The Fund entered into forward foreign currency exchange contracts for the fiscal year ended December 31, 2016 (as described in note 2(g)). A forward foreign currency exchange contract reduces the Fund’s exposure to changes in the value of the currency it will deliver (or settle in cash) and increases its exposure to changes in the value of the currency it will receive (or settle in cash) for the duration of the contract. The Fund’s use of forward foreign currency exchange contracts involves the risk that Lord Abbett will not accurately predict currency movements, and the Fund’s returns could be reduced as a result. Forward foreign currency exchange contracts are subject to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of hedged positions, that the U.S. dollar will decline relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time. The Fund’s risk of loss from counterparty credit risk is the unrealized appreciation on forward foreign currency exchange contracts and deposits with brokers as collateral.

The Fund entered into U.S. Treasury futures contracts for the fiscal year ended December 31, 2016 (as described in note 2(h)) to hedge against changes in interest rates. The Fund bears the risk of interest rates moving unexpectedly, in which case the Fund may not achieve the anticipated benefits of the futures contracts and realize a loss. There is minimal counterparty credit risk to the Fund since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees futures against default.

54

Notes to Financial Statements (continued)

As of December 31, 2016, the Fund had the following derivatives at fair value, grouped into appropriate risk categories that illustrate the Funds use of derivative instruments:

Asset Derivatives	Interest Rate Contracts	Foreign Currency Contracts
Forward Foreign Currency Exchange Contracts(1)	–	$964
Futures Contracts(2)	$1,241	–
Liability Derivatives
Futures Contracts(2)	$2,785	–

(1)	Statements of Assets and Liabilities location: Unrealized appreciation on forward foreign currency exchange contracts.
(2)	Statements of Assets and Liabilities location: Includes cumulative unrealized appreciation/depreciation of futures contracts as reported in the Schedule of Investments. Only current day’s variation margin is reported within the Statements of Assets and Liabilities.

Transactions in derivative instruments for the year ended December 31, 2016, were as follows:

	Interest Rate Contracts			Forward Currency Contracts
Net Realized Gain (Loss)(1)
Futures Contracts	$	(59,522	)	$	–
Net Change in Unrealized Appreciation/Depreciation(2)
Forward Foreign Currency Exchange Contracts	$	–		$	964
Futures Contracts		1,936			–
Average Number of Contracts/Notional Amounts*
Forward Foreign Currency Exchange Contracts(3)	$	–		$	6,253
Futures Contracts(4)		51			–

*	Calculated based on the number of contracts or notional amounts for the fiscal year ended December 31, 2016.
(1)	Statements of Operations location: Net realized loss on futures contracts and foreign currency related transactions.
(2)	Statements of Operations location: Net change in unrealized appreciation/depreciation on futures contracts and translation of assets and liabilities denominated in foreign currencies.
(3)	Amount represents notional amounts in U.S. dollars.
(4)	Amount represents number of contracts.

7. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES   

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

8. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

9. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

10. LINE OF CREDIT  

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

56

Notes to Financial Statements (continued)

11. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

12. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

13. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with investing in fixed income securities. The value of an investment will change as interest rates fluctuate and in response to market movements. When interest rates rise, the prices of fixed income securities are likely to decline; when interest rates fall, such prices tend to rise. Longer-term securities are usually more sensitive to interest rate changes. There is also the risk that an issuer of a fixed income security will fail to make timely payments of principal and/or interest to the Fund, a risk that is greater with high-yield bonds (sometimes called “junk bonds”) in which the Fund may substantially invest. Some issuers, particularly of high-yield bonds, may default as to principal and/or interest payments after the Fund purchases its securities. A default, or concerns in the market about an increase in risk of default, may result in losses to the Fund. High-yield bonds are subject to greater price fluctuations, as well as additional risks.

The Fund is subject to the general risks and considerations associated with investing in convertible securities, which have both equity and fixed income risk characteristics. Generally, convertible securities offer lower interest or dividend yields than non-convertible securities of similar quality and less potential for gains or capital appreciation in a rising equity securities market than equity securities. They tend to be more volatile than other fixed income securities, and the markets for convertible securities may be less liquid than markets for stocks or bonds. A significant portion of convertible securities have below investment grade credit ratings and are subject to increased credit and liquidity risks.

The Fund’s investment exposure to foreign (which may include emerging market) companies presents increased market, liquidity, currency, political, information and other risks. The cost of the Fund’s potential use of forward foreign currency exchange contracts varies with factors such as the currencies involved, the length of the contract period and the market conditions prevailing.

The Fund is subject to the risks associated with derivatives, which may be different from and greater than the risks associated with directly investing in securities. Derivatives may be subject to risks such as liquidity risk, leveraging risk, interest rate risk, market risk, and credit risk. Illiquid securities may lower the Fund’s returns since the Fund may be unable to sell these securities at their desired time or price. Derivatives also may involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the value

57

Notes to Financial Statements (concluded)

of the underlying asset, rate or index. Whether the Fund’s use of derivatives is successful will depend on, among other things, the Fund’s ability to correctly forecast market movements, changes in foreign exchange and interest rates, and other factors. If the Fund incorrectly forecasts these and other factors, its performance could suffer. The Fund’s use of derivatives could result in a loss exceeding the amount of the Fund’s investment in these instruments.

The Fund may invest in swap contracts. Swap contracts are bi-lateral agreements between a fund and its counterparty. Each party is exposed to the risk of default by the other. In addition, they may involve a small investment of cash compared to the risk assumed with the result that small changes may produce disproportionate and substantial gains or losses to the Fund.

The Fund may invest in credit default swap contracts. The risks associated with the Fund’s investment in credit default swaps are greater than if the Fund invested directly in the reference obligation because they are subject to illiquidity risk, counterparty risk, and credit risk at both the counterparty and underlying issuer levels.

The Fund may invest in floating rate or adjustable rate senior loans, which are subject to increased credit and liquidity risks. Senior loans are business loans made to borrowers that may be U.S. or foreign corporations, partnerships or other business entities. The senior loans in which the Fund may invest may consist primarily of senior loans that are rated below investment grade or, if unrated, deemed by Lord Abbett to be equivalent to below investment grade securities. Below investment grade senior loans, as in the case of high-yield debt securities, or junk bonds, are usually more credit sensitive than interest rate sensitive, although the value of these instruments may be impacted by broader interest rate swings in the overall fixed income market.

The Fund may invest in mortgage-related securities, including those of such Government sponsored enterprises as Federal Home Loan Mortgage Corporation and Federal National Mortgage Association. In addition, the Fund may invest in non-agency backed and mortgage related securities, which are issued by the private institutions, not by the government-sponsored enterprises. Such securities may be particularly sensitive to changes in economic conditions, including delinquencies and/or defaults, and changes in prevailing interest rates. These changes can affect the value, income and/or liquidity of such positions. When interest rates are declining, the value of these securities with prepayment features may not increase as much as other fixed income securities. Early principal repayment may deprive the Fund of income payments above current markets rates. The prepayment rate also will affect the price and volatility of a mortgage-related security. In addition, securities of government sponsored enterprises are guaranteed with respect to the timely payment of interest and principal by the particular enterprise involved, not by the U.S. Government.

These factors can affect the Fund’s performance.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Short Duration Income Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Short Duration Income Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian, brokers, and agent banks; when replies were not received from brokers and agent banks, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Short Duration Income Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets, and the financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of the Fund’s benchmark; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and the Fund’s benchmark as of the trailing one-year period ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the period. The Board also considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds

65

Approval of Advisory Contract (continued)

overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was equal to the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible

66

Approval of Advisory Contract (concluded)

benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

Director, President and Chief Executive Officer

For the fiscal year ended December 31, 2016, the Fund returned 4.26%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the Bloomberg Barclays U.S. Universal Index,¹ which returned 3.91% over the same period.

Yields on longer-dated Treasury bonds were relatively flat, rising only slightly over the 12-month period ended December 31, 2016, while the yield on shorter-dated two-year Treasury notes increased 0.18% over

the same period, leading to a slight flattening of the Treasury yield curve. Corporate credit spreads narrowed over the 12-month period, particularly within lower-rated, investment grade debt. Consumer prices rose at a moderate pace, with the Consumer Price Index (CPI) rising 2.1% over the 12-month period ended December 31, 2016. Meanwhile, the employment picture continued to improve as the unemployment rate remained steady at 4.7%, with 156,000 jobs added in December 2016; employment growth has averaged 165,000 per month,

1

over the last three months. This compares with an unemployment rate of 5.0% a year earlier and a recent high of 10.0% in October 2009. In December, the U.S. Federal Reserve (Fed) raised its target for short-term interest rates 0.25%, to a range of 0.50% - 0.75%, as economic data continued to suggest a strengthening domestic economy.

Spreads on investment grade corporates tightened from January 2016 to December 2016, while spreads on high yield corporates narrowed much more significantly. In the 12-month period ended December 2016, high yield corporates comfortably outperformed the investment grade segment of the fixed income market, including both investment grade corporates and Treasuries.

Security selection within the corporate bond allocation was a significant

contributor to performance of the Fund relative to the benchmark during the period. Within the investment grade corporate sector, the Fund concentrated on ‘BBB’ rated bonds, which outperformed higher-rated issues. The Fund’s overweight to high yield corporate bonds also contributed to relative performance.

The Fund’s sector allocation related to the sovereign issues of both developed countries and emerging markets detracted from relative performance, as sovereign debt outperformed the broad fixed income market.

The Fund’s portfolio is actively managed and, therefore, its holdings and the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹ The Bloomberg Barclays U.S. Universal Index represents the union of the U.S. Aggregate Index, the U.S High Yield Corporate Index, the 144A Index, the Eurodollar Index, the Emerging Markets Index, and the non-ERISA portion of the CMBS Index. Municipal debt, private placements, and non-dollar-denominated issues are excluded from the Universal Index. The only constituent of the index that includes floating-rate debt is the Emerging Markets Index.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may

be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities. Because the Fund’s portfolio is actively managed and may change significantly, the Fund may no longer own the securities described above or may have otherwise changed their positions in the securities. For more recent information about the Fund’s portfolio holdings, please visit www.lordabbett.com.

A Note about Risk: See Notes to Financial Statements for a discussion of investment risks. For a more detailed discussion of the risks associated with each Fund, please see the Fund’s prospectus.

Mutual funds are not insured by the FDIC, are not deposits or other obligations of, or guaranteed by,

banks, and are subject to investment risks including possible loss of principal amount invested.

The Fund serves as an underlying investment vehicle for variable annuity contracts and variable life insurance policies.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in both the Bloomberg Barclays U.S. Universal Index and the Bloomberg Barclays U.S. Aggregate Bond Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. The line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During the period, expenses of the Fund were waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

 

	Average Annual Total Returns for the Periods Ended December 31, 2016
	1 Year	5 Years	Life of Class

¹ Performance for each unmanaged index does not reflect any fees or expenses. The performance of each index is not necessarily representative of the Fund’s performance. Performance for each index began on May 1, 2010.

² The Class VC shares commenced operations on April 16, 2010. Performance for the Class began on May 1, 2010.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Hypothetical (5% Return Before Expenses)	$1,000.00	$1,021.92	$3.25

† Net expenses are equal to the Fund’s annualized expense ratio of 0.64%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION   

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (“the Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Total Return Portfolio (the “Fund”).

The Fund’s investment objective is to seek income and capital appreciation to produce a high total return. The Fund has Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES   

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices. Fixed income securities are valued based on evaluated prices supplied by independent pricing services, which reflect broker/dealer supplied valuations and the independent pricing services’ own electronic data processing techniques. Exchange traded options and futures contracts are valued at the last sale price in the market where they are principally traded. If no sale has occurred, the mean between the most recently quoted bid and asked prices is used.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values, yield curves, broker quotes, observable trading activity, option adjusted spread models

34

Notes to Financial Statements (continued)

	and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.
(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Foreign Transactions–The books and records of the Fund are maintained in U.S. dollars and transactions denominated in foreign currencies are recorded in the Fund’s records at the rate prevailing when earned or recorded. Asset and liability accounts that are denominated in foreign currencies are adjusted daily to reflect current exchange rates and any unrealized gain (loss) is included in Net change in unrealized appreciation/depreciation on futures contracts in the Fund’s Statement of Operations. The resultant exchange gains and losses upon settlement of such transactions are included in Net realized gain on futures contracts in the Fund’s Statement of Operations. The Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in market prices of the securities.
(g)	Futures Contracts–The Fund may purchase and sell futures contracts to enhance returns, to attempt to economically hedge some of its investment risk, or as a substitute position in lieu of holding the underlying asset on which the instrument is based. At the time of entering into a futures transaction, an investor is required to deposit and maintain a specified amount of cash or eligible securities called “initial margin.” Subsequent payments made or received by the Fund called “variation margin” are made on a daily basis as the market price of the futures

35

Notes to Financial Statements (continued)

	contract fluctuates. The Fund will record an unrealized gain (loss) based on the amount of variation margin. When a contract is closed, a realized gain (loss) is recorded equal to the difference between the opening and closing value of the contract.
(h)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.
(i)	When-Issued, Forward Transactions or To-Be-Announced (“TBA”) Transactions–The Fund may purchase portfolio securities on a when-issued or forward basis. When-issued, forward transactions or TBA transactions involve a commitment by a fund to purchase securities, with payment and delivery (“settlement”) to take place in the future, in order to secure what is considered to be an advantageous price or yield at the time of entering into the transaction. During the period between purchase and settlement, the fair value of the securities will fluctuate and assets consisting of cash and/or marketable securities (normally short-term U.S. Government or U.S. Government sponsored enterprise securities) marked to market daily in an amount sufficient to make payment at settlement will be segregated at the Fund’s custodian in order to pay for the commitment. At the time the Fund makes the commitment to purchase a security on a when-issued basis, it will record the transaction and reflect the liability for the purchase and fair value of the security in determining its net asset value (“NAV”). The Fund, generally, has the ability to close out a purchase obligation on or before the settlement date rather than take delivery of the security. Under no circumstances will settlement for such securities take place more than 120 days after the purchase date.
(j)	Mortgage Dollar Rolls–The Fund may enter into mortgage dollar rolls in which a fund sells mortgage-backed securities for delivery in the current month and simultaneously contracts with the same counterparty to repurchase similar (same type, coupon and maturity) but not identical securities on a specified future date. During the roll period, the Fund loses the right to receive principal (including prepayments of principal) and interest paid on the securities sold.
(k)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources

36

Notes to Financial Statements (continued)

independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

•	Level 1 –	unadjusted quoted prices in active markets for identical investments;
•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES   

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.45%
Next $1 billion	.40%
Over $2 billion	.35%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of .20% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of ..04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses to an annual rate of .64%. This agreement may be terminated only by the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract

owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS   

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended		Year Ended
	12/31/2016		12/31/2015
Distributions paid from:
Ordinary income	$	13,372,681	$	11,074,615
Total distributions paid	$	13,372,681	$	11,074,615

As of December 31, 2016, the components of accumulated losses on a tax-basis were as follows:

Undistributed ordinary income – net	$	10,357
Total undistributed earnings		10,357
Temporary differences		(4,583,145	)
Unrealized losses – net		(5,323,918	)
Total accumulated losses – net	$	(9,896,706	)

At the Fund’s election, certain losses incurred within the taxable year (Qualified Late-Year Losses) are deemed to arise on the first business day of the Fund’s next taxable year. The Fund incurred and will elect to defer post-October capital losses of $4,556,475 during fiscal 2016.

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	506,017,693
Gross unrealized gain		3,490,073
Gross unrealized loss		(8,716,881	)
Net unrealized security loss	$	(5,226,808	)

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to the tax treatment of premium amortization and wash sales.

Notes to Financial Statements (continued)

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Distributions in	Accumulated
Excess of Net	Net Realized
Investment Income	Loss
$2,539,091	$(2,539,091	)

The permanent differences are attributable to the tax treatment of premium amortization, principal paydown gains and losses, certain securities and certain distributions.

5. PORTFOLIO SECURITIES TRANSACTIONS   

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

U.S.		Non-U.S.	U.S.		Non-U.S.
Government		Government	Government		Government
Purchases	*	Purchases	Sales	*	Sales
$1,945,905,931		$171,972,548	$1,874,649,460		$120,243,092

* Includes U.S. Government sponsored enterprises securities.

The Fund is permitted to purchase and sell securities ( “cross-trade”) from and to other Lord Abbett funds or client accounts pursuant to procedures approved by the Board in compliance with Rule 17a-7 under the Act (the “Rule”). Each cross-trade is executed at a fair market price in compliance with provisions of the Rule. For the period ended December 31, 2016, the Fund engaged in cross-trades purchases of $813,952 and sales of $474,154, which resulted in net realized gain of $27,926.

6. DISCLOSURES ABOUT DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES   

The Fund entered into U.S. Treasury futures contracts for the fiscal year ended December 31, 2016 (as described in note 2(g)) to hedge against changes in interest rates. The Fund bears the risk of interest rates moving unexpectedly, in which case the Fund may not achieve the anticipated benefits of the futures contracts and realize a loss. There is minimal counterparty credit risk to the Fund since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees futures against default.

As of December 31, 2016, the Fund had futures contracts with unrealized appreciation of $54,863 and depreciation of $44,674 which is included in the Schedule of Investments. Only current day’s variation margin is reported within the Fund’s Statement of Assets and Liabilities. Net realized loss of $(109,574) and net change in unrealized appreciation of $23,366 are included on the Statement of Operations related to futures contracts under the captions Net realized gain on futures contracts and Net change in unrealized appreciation/depreciation on futures contracts, respectively. The average number of futures contracts throughout the period was 366.

7. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES   

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net

39

Notes to Financial Statements (continued)

settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty:

		Gross Amounts	Net Amounts of
		Offset in the	Assets Presented
	Gross Amounts of	Statement of Assets	in the Statement of
Description	Recognized Assets	and Liabilities	Assets and Liabilities
Repurchase Agreement	$658,414	$ –	$658,414
Total	$658,414	$ –	$658,414

	Net Amounts
	of Assets	Amounts Not Offset in the
	Presented in	Statement of Assets and Liabilities
	the Statement		Cash	Securities
	of Assets and	Financial	Collateral	Collateral	Net
Counterparty	Liabilities	Instruments	Received(a)	Received(a)	Amount(b)
Fixed Income Clearing Corp.	$658,414	$          –	$          –	$(658,414)	$              –
Total	$658,414	$          –	$          –	$(658,414)	$              –

(a)	Collateral disclosed is limited to an amount not to exceed 100% of the net amount of assets presented in the Statement of Assets and Liabilities, for each respective counterparty.
(b)	Net amount represents the amount owed to the Fund by the counterparty as of December 31, 2016.

8. DIRECTORS’ REMUNERATION   

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

9. EXPENSE REDUCTIONS   

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

10. LINE OF CREDIT   

The Fund and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) entered into a syndicated line of credit facility with various lenders for $550 million (the “Facility”), whereas State Street Bank and Trust Company (“SSB”) participates as a lender and as agent for the lenders. The Facility is to be used for temporary or emergency purposes as an additional source of liquidity to satisfy redemptions. The Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million,

40

Notes to Financial Statements (continued)

or $350 million, based on past borrowings and likelihood of future borrowings. The Facility will continue through August 28, 2017.

During the fiscal year ended December 31, 2016, the Fund did not utilize the Facility.

11. INTERFUND LENDING PROGRAM   

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

12. CUSTODIAN AND ACCOUNTING AGENT   

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

13. INVESTMENT RISKS   

The Fund is subject to the general risks and considerations associated with investing in fixed income securities. The value of an investment will change as interest rates fluctuate in response to market movements. When interest rates rise, the prices of fixed income securities are likely to decline; when interest rates fall, such prices tend to rise.

The Fund may invest a significant portion of its assets in asset backed securities and mortgage related securities, including those of such government sponsored enterprises as Federal Home Loan Mortgage Corporation and Federal National Mortgage Association. In addition, the Fund may invest in non-agency asset backed and mortgage related securities, which are issued by private institutions, not by government-sponsored enterprises. Such securities may be particularly sensitive to changes in economic conditions, including delinquencies and/or defaults, and changes in prevailing interest rates. These changes can affect the value, income and/or liquidity of such positions. When interest rates are declining, the value of these securities with prepayment features may not increase as much as other fixed income securities. Early principal repayment may deprive the Fund of income payments above current market rates. The prepayment rate also will affect the price and volatility of these securities. In addition, securities of government sponsored enterprises are guaranteed with respect to the timely payment of interest and principal by the particular enterprises involved, not by the U.S. Government.

The lower-rated or high-yield bonds (also known as “junk” bonds) in which the Fund may invest are subject to greater price fluctuations, as well as additional risks.

The Fund is subject to the risks associated with derivatives, which may be different from and greater than the risks associated with directly investing in securities. Derivatives may be subject to risks such as liquidity risk, leveraging risk, interest rate risk, market risk, and credit risk. Illiquid securities may lower the Fund’s returns since the Fund may be unable to sell these securities at their desired time or price. Derivatives also may involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative may not correlate perfectly with the value

41

Notes to Financial Statements (concluded)

of the underlying asset, rate or index. Whether the Fund’s use of derivatives is successful will depend on, among other things, the Fund’s ability to correctly forecast market movements, changes in foreign exchange and interest rates, and other factors. If the Fund incorrectly forecasts these and other factors, its performance could suffer.

The Fund’s investment exposure to foreign (which may include emerging market) companies presents increased market, liquidity, currency, political, information and other risks. The cost of the Fund’s use of forward foreign currency exchange contracts varies with factors such as the currencies involved, the length of the contract period and the market conditions prevailing. The Fund’s exposure to inflation-linked investments, such as Treasury Inflation Protected Securities, may be vulnerable to changes in expectations of inflation or interest rates.

The Fund may invest in floating rate or adjustable rate senior loans, which are subject to increased credit and liquidity risks. Senior loans are business loans made to borrowers that may be U.S. or foreign corporations, partnerships or other business entities. The senior loans in which the Fund invests may consist primarily of senior loans that are rated below investment grade or, if unrated, deemed by Lord Abbett to be equivalent to below investment grade securities. Below investment grade senior loans, as in the case of high-yield debt securities, or junk bonds, are usually more credit sensitive than interest rate sensitive, although the value of these instruments may be impacted by broader interest rate swings in the overall fixed income market.

These factors can affect the Fund’s performance.

14. SUMMARY OF CAPITAL TRANSACTIONS

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Total Return Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Total Return Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Total Return Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was below the median of the performance peer group for the one-year, three-year and five-year periods. The Board also observed that the Fund’s investment performance was above the investment

49

Approval of Advisory Contract (continued)

performance of the two benchmarks for the one-year, three-year and five-year periods. The Board considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was below the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was reasonable and supported the continuation of the Agreement.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than

50

Approval of Advisory Contract (concluded)

investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

For the fiscal year ended December 31, 2016, the Fund returned 17.02%, reflecting performance at the net asset value (NAV) of Class VC shares, with all distributions reinvested, compared to its benchmark, the Russell 2500™ Index,¹ which returned 17.59% over the same period.

Domestic equity markets (as represented by the S&P 500^® Index²) returned 11.96% over the past year. Despite this general move higher, there were significant bouts of volatility within U.S. stock markets, including their worst start to a calendar year on record.

Crude oil prices played a significant role in the increased market volatility, as Brent oil prices fluctuated sharply throughout the fiscal year. In December, the Organization of Petroleum Exporting Countries agreed to reduce oil production effective 2017. Furthermore, global markets were affected by the devaluation of China’s currency and weak economic data out of the region. The Chinese economy advanced at an annual rate of 6.7% in the third quarter of 2016, a slower pace than in recent years.

1

Geopolitical events also contributed to volatility in global markets. The United Kingdom’s referendum in June to leave the European Union (“Brexit”) was a surprise that caused a sell-off in global markets.

In contrast to the equity market volatility, the U.S. economy continued to expand during the trailing 12-month period. The Federal Reserve (Fed) raised target rates for the second time in 12 months in December, from 0.25%–0.50% to 0.50%–0.75%. U.S. gross domestic product (GDP) grew at a 3.2% pace during the third quarter, a significant increase over the second quarter. The U.S. Bureau of Economic Analysis stated that during the third-quarter personal consumption and federal government spending increased, quarter over quarter. In addition to GDP growth, the U.S. unemployment rate remained relatively steady throughout the period, finishing at 4.6% in November.

The U.S. presidential election took an unexpected turn as Donald J. Trump was elected president, in contrast to indications from poll numbers before the election. Markets rallied on improved clarity in the U.S. political agenda, with the House and Senate also under Republican control.

Security selection in the consumer discretionary sector, as well as security selection and an underweight in the industrials sector, were main detractors from the Fund’s relative performance during the period. Within the consumer discretionary sector, SeaWorld Entertainment Inc., a theme park and

entertainment company, detracted most. Shares of SeaWorld Entertainment fell as the company missed consensus revenue and earnings expectations, largely due to a miss in expected attendance in the second quarter of 2016. AMC Networks Inc., an owner and operator of entertainment businesses and assets, also detracted. Shares of AMC Networks suffered as increased competition and lower-than-expected new show viewership belabored the company.

Within the industrials sector, Snap-On, Inc., a manufacturer of diagnostic and repair solutions, detracted from performance. Snap-On posted strong fourth quarter earnings but faced headwinds from a soft commercial and industrial production market.

Conversely, security selection in the health care and energy sectors contributed to the Fund’s performance relative to the benchmark. Within the health care sector, ExamWorks Group, Inc., a provider of independent medical examinations and medical-related services, contributed most. Shares of ExamWorks increased following the announcement that the company would be acquired by Leonard Green & Partners, L.P. HealthSouth Corp., an owner and operator of inpatient rehabilitation hospitals, also contributed. HealthSouth beat consensus first quarter earnings expectations due to strong growth and free cash flow.

Within the energy sector, Rice Energy, Inc., an independent natural gas and oil

2

company, contributed most. Shares of Rice Energy rose due to increased production and a reduction in costs.

The Fund’s portfolio is actively managed and, therefore, its holdings and

the weightings of a particular issuer or particular sector as a percentage of portfolio assets are subject to change. Sectors may include many industries.

¹ The Russell 2500™ Index is a market cap weighted index that includes the smallest 2,500 companies covered in the Russell 3000^® universe of United States-based listed equities.

² The S&P 500^® Index is widely regarded as the standard for measuring large cap U.S. stock market performance and includes a representative sample of leading companies in leading industries.

Unless otherwise specified, indexes reflect total return, with all dividends reinvested. Indexes are unmanaged, do not reflect the deduction of fees or expenses, and are not available for direct investment.

Important Performance and Other Information

Performance data quoted in the following pages reflect past performance and are no guarantee of future results. Current performance may be higher or lower than the performance quoted. The investment return and principal value of an investment in the Funds will fluctuate so that shares, on any given day or when redeemed, may be worth more or less than their original cost. You can obtain performance data current to the most recent month end by calling Lord Abbett at 888-522-2388 or referring to www.lordabbett.com.

During certain periods shown, expense waivers and reimbursements were in place. Without such expense

waivers and reimbursements, the Funds’ returns would have been lower.

The annual commentary above discusses the views of the Fund’s management and various portfolio holdings of the Funds as of December 31, 2016. These views and portfolio holdings may have changed after this date. Information provided in the commentary is not a recommendation to buy or sell securities.

Investment Comparison

Below is a comparison of a $10,000 investment in Class VC shares with the same investment in the Russell 2500™ Index and the Russell 2500™ Value Index, assuming reinvestment of all dividends and distributions. The Fund’s shares are sold only to insurance company separate accounts that fund certain variable annuity and variable life contracts. The line graph comparison does not reflect the sales charges or other expenses of these contracts. If those sales charges and expenses were reflected, returns would be lower. The graph and performance table below do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. During the period, expenses of the Fund were waived or reimbursed by Lord Abbett; without such waiver or reimbursement of expenses, the Fund’s returns would have been lower. Past performance is no guarantee of future results.

Expense Example

As a shareholder of the Fund, you incur ongoing costs, including management fees; expenses related to the Fund’s services arrangements with certain insurance companies; and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (July 1, 2016 through December 31, 2016).

The Example reflects only expenses that are deducted from the assets of the Fund. Fees and expenses, including sales charges applicable to the various insurance products that invest in the Fund, are not reflected in this Example. If such fees and expenses were reflected in the Example, the total expenses shown would be higher. Fees and expenses regarding such variable insurance products are separately described in the prospectus related to those products.

Actual Expenses

The first line of the table on the following page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 7/1/16 – 12/31/16” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

5

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning	Ending	Expenses
	Account	Account	Paid During
	Value	Value	Period†
			7/1/16-
	7/1/16	12/31/16	12/31/16

Actual	$1,000.00	$1,110.20	$5.83
Hypothetical (5% Return Before Expenses)	$1,000.00	$1,019.61	$5.58

^† Net expenses are equal to the Fund’s annualized expense ratio of 1.10%, multiplied by the average account value over the period, multiplied by 184/366 (to reflect one-half year period).

Notes to Financial Statements

1. ORGANIZATION  

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a diversified, open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of thirteen separate portfolios. This report covers Value Opportunities Portfolio (the “Fund”).

The Fund’s investment objective is long-term capital appreciation. The Fund offers Variable Contract class shares (“Class VC Shares”), which are currently issued and redeemed only in connection with investments in, and payments under, variable annuity contracts and variable life insurance policies issued by life insurance and insurance-related companies.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a)	Investment Valuation–Under procedures approved by the Fund’s Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Fund to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities actively traded on any recognized U.S. or non-U.S. exchange or on The NASDAQ Stock Market LLC are valued at the last sale price or official closing price on the exchange or system on which they are principally traded. Events occurring after the close of trading on non-U.S. exchanges may result in adjustments to the valuation of foreign securities to reflect their fair value as of the close of regular trading on the New York Stock Exchange. The Fund may utilize an independent fair valuation service in adjusting the valuations of foreign securities. Unlisted equity securities are valued at the last quoted sale price or, if no sale price is available, at the mean between the most recently quoted bid and asked prices.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use related or comparable assets or liabilities, recent transactions, market multiples, book values and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.

16

Notes to Financial Statements (continued)

(b)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statement of Operations. Withholding taxes on foreign dividends have been provided for in accordance with the applicable country’s tax rules and rates.
(d)	Income Taxes–It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.
	The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s filed U.S. federal tax returns remains open for the fiscal years ended December 31, 2013 through December 31, 2016. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the funds within the Company on a pro rata basis by relative net assets.
(f)	Repurchase Agreements–The Fund may enter into repurchase agreements with respect to securities. A repurchase agreement is a transaction in which a fund acquires a security and simultaneously commits to resell that security to the seller (a bank or securities dealer) at an agreed-upon price on an agreed-upon date. The Fund requires at all times that the repurchase agreement be collateralized by cash, or by securities of the U.S. Government, its agencies, its instrumentalities, or U.S. Government sponsored enterprises having a value equal to, or in excess of, the value of the repurchase agreement (including accrued interest). If the seller of the agreement defaults on its obligation to repurchase the underlying securities at a time when the fair value of these securities has declined, the Fund may incur a loss upon disposition of the securities.
(g)	Fair Value Measurements–Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk—for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances.

17

Notes to Financial Statements (continued)

The three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

•	Level 1 –	unadjusted quoted prices in active markets for identical investments;
•	Level 2 –	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2016 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the fiscal year then ended is included in the Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES  

Management Fee

The Company has a management agreement with Lord Abbett, pursuant to which Lord Abbett supplies the Fund with investment management services and executive and other personnel, provides office space and pays for ordinary and necessary office and clerical expenses relating to research and statistical work and supervision of the Fund’s investment portfolio.

The management fee is based on the Fund’s average daily net assets at the following annual rate:

First $1 billion	.75%
Next $1 billion	.70%
Over $2 billion	.65%

For the fiscal year ended December 31, 2016, the effective management fee, net of waivers, was at an annualized rate of .00% of the Fund’s average daily net assets.

In addition, Lord Abbett provides certain administrative services to the Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of the Fund’s average daily net assets.

During the fiscal year ended December 31, 2016 and continuing through April 30, 2017, Lord Abbett has contractually agreed to waive its fees and reimburse expenses to the extent necessary to limit total net annual operating expenses to an annual rate of 1.10%. This agreement may be terminated only upon the approval of the Board.

The Company, on behalf of the Fund, has entered into services arrangements with certain insurance companies. Under these arrangements, certain insurance companies will be compensated up to .25% of the average daily net asset value (“NAV”) of the Fund’s Class VC Shares held in the insurance company’s separate account to service and maintain the Variable Contract owners’ accounts. This amount is included in Non 12b-1 service fees on the Statement of Operations. The Fund may also compensate certain insurance companies, third-party administrators and other entities for providing recordkeeping, sub-transfer agency and other

18

Notes to Financial Statements (continued)

administrative services to the Fund. This amount is included in Shareholder servicing on the Statement of Operations.

Two Directors and certain of the Company’s officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared and paid at least semi-annually. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions that exceed earnings and profits for tax purposes are reported as a tax return of capital.

The tax character of distributions paid during the fiscal years ended December 31, 2016 and 2015 was as follows:

	Year Ended		Year Ended
	12/31/2016		12/31/2015
Distributions paid from:
Ordinary income	$	898	$	39
Net long-term capital gains		23,703		13,001
Total distributions paid	$	24,601	$	13,040

As of December 31, 2016, the components of accumulated gains on a tax-basis were as follows:

Undistributed ordinary income – net	$	293
Total undistributed earnings		293
Temporary differences		(889	)
Unrealized gains – net		70,064
Total accumulated gains – net	$	69,468

At the Fund’s election, certain losses incurred within the taxable year (Qualified Late-Year Losses) are deemed to arise on the first business day of the Fund’s next taxable year. The Fund’s incurred and will elect to defer post-October capital losses of $848 during fiscal 2016.

As of December 31, 2016, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

Tax cost	$	368,670
Gross unrealized gain		75,567
Gross unrealized loss		(5,503	)
Net unrealized security gain	$	70,064

The difference between book-basis and tax-basis unrealized gains (losses) is attributable to wash sales.

19

Notes to Financial Statements (continued)

Permanent items identified during the fiscal year ended December 31, 2016 have been reclassified among the components of net assets based on their tax basis treatment as follows:

Undistributed Net Investment Income			Accumulated Net Realized Loss		Paid-in Capital
	$ (1	)		$ 47		$ (46	)

The permanent differences are attributable to the tax treatment of certain distributions, certain securities, and net investment losses.

5. PORTFOLIO SECURITIES TRANSACTIONS  

Purchases and sales of investment securities (excluding short-term investments) for the fiscal year ended December 31, 2016 were as follows:

Purchases	Sales
$176,377	$167,667

There were no purchases or sales of U.S. Government securities for the fiscal year ended December 31, 2016.

6. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosures intended to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. The following tables illustrate gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Fund’s accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between the Fund and the applicable counterparty. As of December 31, 2016, the Fund did not have assets or liabilities subject to the FASB disclosure requirements.

7. DIRECTORS’ REMUNERATION  

The Company’s officers and two Directors, who are associated with Lord Abbett, do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statement of Operations and in Directors’ fees payable on the Statement of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

20

Notes to Financial Statements (concluded)

8. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund’s expenses.

9. INTERFUND LENDING PROGRAM  

On July 26, 2016, the U.S. Securities and Exchange Commission issued an exemptive order (“SEC exemptive order”) which permits certain registered open-end management investment companies managed by Lord Abbett, including the Fund, to participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the fiscal year ended December 31, 2016, the Fund did not participate as a borrower or lender in the Interfund Lending Program.

10. CUSTODIAN AND ACCOUNTING AGENT  

State Street Bank and Trust Company (“SSB”) is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating the Fund’s NAV.

11. INVESTMENT RISKS  

The Fund is subject to the general risks and considerations associated with equity investing, as well as the particular risks associated with value stocks. The value of an investment will fluctuate in response to movements in the equity securities market in general and to the changing prospects of individual companies in which the Fund invests. Small and mid-sized company stocks, in which the Fund invests, may perform differently than the market as a whole and other types of stocks, such as large-company and growth stocks. This is because different types of stocks tend to shift in and out of favor depending on market and economic conditions. The market may fail to recognize the intrinsic value of particular value stocks for a long time. In addition, if the Fund’s assessment of a company’s value or prospects for exceeding earnings expectations or market conditions is wrong, the Fund could suffer losses or produce poor performance relative to other funds, even in a rising market.

Due to the Fund’s investment exposure to foreign companies and American Depositary Receipts, the Fund may experience increased market, liquidity, currency, political, information and other risks.

These factors can affect the Fund’s performance.

12. SUMMARY OF CAPITAL TRANSACTIONS  

Transactions in shares of capital stock were as follows:

	Year Ended			Year Ended
	December 31, 2016			December 31, 2015
Shares sold		–			185
Reinvestment of distributions		1,199			695
Shares reacquired		(389	)		(863	)

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Lord Abbett Series Fund, Inc. and the Shareholders of Value Opportunities Portfolio:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of the Value Opportunities Portfolio, one of the portfolios constituting the Lord Abbett Series Fund, Inc. (the “Fund”) as of December 31, 2016, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016, by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Value Opportunities Portfolio of the Lord Abbett Series Fund, Inc. as of December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

Approval of Advisory Contract

The Board, including all of the Directors who are not interested persons of the Fund or of Lord Abbett (the “Independent Board Members”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to the Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the review of the portfolio management team conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Board Members also met with their independent legal counsel in a private session at which no representatives of management were present.

The materials received by the Board included, but were not limited to: (1) information provided by Morningstar Associates, LLC (“Morningstar”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Morningstar, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of two appropriate benchmarks; (2) information provided by Morningstar regarding the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to the Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that the Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance. The Board reviewed the Fund’s investment performance in relation to that of the performance peer group and two appropriate benchmarks as of various periods ended August 31, 2016. The Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-year, three-year and five-year periods. The Board also considered Lord Abbett’s performance and reputation generally, the performance of other Lord

28

Approval of Advisory Contract (continued)

Abbett-managed funds overseen by the Board and the willingness of Lord Abbett to take steps intended to improve performance when necessary. After reviewing these and related factors, the Board concluded that the Fund’s investment performance was reasonable and supported the continuation of the Agreement.

Lord Abbett’s Personnel and Methods. The Board considered the qualifications of the personnel providing investment management services to the Fund, in light of its investment objective and discipline. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including the Fund’s transfer agent and custodian.

Expenses. The Board considered the expense level of the Fund and the expense levels of the expense peer group. It also considered how the expense levels of the Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. The Board observed that the overall expense level of the Fund was above the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of the Fund was not unreasonable in light of the Fund’s small size.

Profitability. The Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether the Fund was profitable to Lord Abbett in connection with the operation of the Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and excluding marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to the Fund was not excessive.

Economies of Scale. The Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that the existing management fee schedule, with its breakpoints in the levels of the management fee, in conjunction with a proposed expense limitation agreement adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett. The Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board observed that

29

Approval of Advisory Contract (concluded)

the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of the Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Fund. The Board also took into consideration the investment research that Lord Abbett receives as a result of Fund brokerage transactions.

Alternative Arrangements. The Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of the Fund and its shareholders and voted unanimously to approve the continuation of the Agreement. In considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.

SOX Code of Ethics dated June, 2003

THE LORD ABBETT FAMILY OF FUNDS

SARBANES-OXLEY CODE OF ETHICS

FOR THE PRINCIPAL EXECUTIVE OFFICER

AND SENIOR FINANCIAL OFFICERS

I.Covered Officers/Purpose of the Code

The Lord Abbett Family of Funds’ code of ethics (the “Code”) for the investment companies within the complex (collectively, “Funds” and each individually a “Fund”), applies to each Fund’s Principal Executive Officer and Senior Financial Officers (the “Covered Officers”, each of whom is set forth in Exhibit A) for the purpose of promoting:

· honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

· full, fair, accurate, timely and understandable disclosure in reports and documents that a registrant files with, or submits to, the SEC and in other public communications made by the Funds;

· compliance with applicable laws and governmental rules and regulations;

· the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

· accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

II. Covered Officers Should Handle Ethically Any Actual and Apparent Conflicts of Interest

Overview. A “conflict of interest” occurs when a Covered Officer’s private interest interferes with the interests of, or his/her service to, a Fund. For example, a conflict of interest would arise if a Covered Officer, or a member of his/her family, receives improper personal benefits as a result of his/her position with a Fund.

Certain conflicts of interest arise out of the relationships between Covered Officers and a Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940 and the Investment Advisers Act of 1940. For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as “affiliated persons” of the investment adviser to each of the Funds. The compliance programs and procedures of Lord, Abbett & Co. LLC (“Lord Abbett”) are designed to prevent, or identify and correct, violations of such requirements. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

June, 2003

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between each of the Funds and Lord Abbett of which the Covered Officers are also members. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for a Fund or for Lord Abbett, or for both), be involved in establishing policies and implementing decisions which will have different effects on Lord Abbett and each of the Funds. The participation of the Covered Officers in such activities is inherent in the contractual relationship between each of the Funds and Lord Abbett and is consistent with the performance by the Covered Officers of their duties as officers of one or more Funds and, if addressed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, will be deemed to have been handled ethically. In addition, it is recognized by the Boards of Directors/Trustees of the Funds that the Covered Officers are also officers of the other Lord Abbett investment companies covered by this and by a separate code of ethics.

Other conflicts of interest are covered by this Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. In reading the following examples of conflicts of interest under this Code, Covered Officers should keep in mind that such a list cannot ever be exhaustive by covering every possible scenario. It follows that the overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of a Fund.

*         *         *         *

Each Covered Officer must:

· not use his/her personal influence or personal relationships improperly to influence investment decisions or financial reporting by a Fund whereby the Covered Officer would benefit personally to the detriment of the Fund; and

· not cause a Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit the Fund.

There are some potential conflict of interest situations that should be discussed with Lord Abbett’s General Counsel if material. Examples of these include:

· service as a director on the board of any public company;

· any direct ownership interest in, or any consulting or employment relationship with, any of the Funds’ service providers, other than Lord Abbett or any affiliated person of Lord Abbett;

· a direct or indirect financial interest in commissions, transaction charges or spreads paid by a Fund for effecting portfolio transactions or for selling or redeeming shares, other than an interest arising from the Covered Officer’s employment, such as compensation or as a member of Lord Abbett.

June, 2003

III.Disclosure & Compliance

· Each Covered Officer should familiarize him/herself with the disclosure requirements generally applicable to the Funds;

· each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about a Fund to others, whether within or outside Lord Abbett or a Fund, including to a Fund’s independent directors/trustees and auditors, and to governmental regulators and self-regulatory organizations;

· each Covered Officer should, to the extent appropriate within his/her area of responsibility, consult with other officers and employees of the Funds and Lord Abbett with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Funds file with, or submit to, the SEC and in other public communications made by the Funds; and

· it is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

IV.Reporting and Accountability

Each Covered Officer must:

· upon adoption of the Code, affirm in writing to the Audit Committee (the “Committee”) of a Fund that he/she has received, read, and understands the Code;

· annually thereafter affirm to the Committee that he/she has complied with the requirements of the Code;

· report at least annually such affiliations or other relationships related to conflicts of interest as covered by the Funds’ Annual Directors & Officers Questionnaire;

· not retaliate against any employee or member of Lord Abbett for reports of potential violations that are made in good faith; and

· notify Lord Abbett’s General Counsel promptly if he/she alleges any violation of this Code. Failure to do so is itself a violation of this Code.

Lord Abbett’s General Counsel is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation. The General Counsel may consult, as appropriate, with the Committee, and/or counsel to the Independent Directors, and is encouraged to do so. However, any approvals or waivers sought by the Covered Persons will be considered by the Committee.

June, 2003

Each of the Funds will follow these procedures in investigating and enforcing this Code:

· Lord Abbett’s General Counsel will take all appropriate action to investigate any potential violations reported to him;

· if, after such investigation, the General Counsel believes that no violation has occurred, the General Counsel is not required to take any further action, but he shall discuss with the Committee at its next regularly scheduled meeting his investigation and conclusion;

· any matter that the General Counsel believes is a violation will be reported to the Committee;

· if the Committee concurs that a violation has occurred, it will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of Lord Abbett; or a recommendation to dismiss the Covered Officer;

· the Committee will be responsible for granting waivers, as appropriate; and

· any changes to or waivers of this Code will, to the extent required, be disclosed as provided by SEC rules.

V.Other Policies and Procedures

This Code shall be the sole code of ethics adopted by the Funds for purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Funds, the Funds’ adviser, principal underwriter, or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superceded by this Code to the extent that they overlap or conflict with the provisions of this Code. The Funds’ and Lord Abbett’s codes of ethics under Rule 17j-1 under the Investment Company Act are separate requirements applying to the Covered Officers and others, and are not part of this Code.

VI.Amendments

Except as to the individuals listed in Exhibit A, this Code may not be amended except in written form, which is specifically approved or ratified by a majority vote of a Fund’s independent directors/trustees.

VII.Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as

June, 2003

otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Committee and its counsel.

VIII.Internal Use

The Code is intended solely for the internal use by each of the Funds and does not constitute an admission, by or on behalf of any Fund, as to any fact, circumstance, or legal conclusion.
