1. ORGANIZATION

Lord Abbett Series Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company and was incorporated under Maryland law in 1989. The Company consists of the following nine portfolios (separately, a “Fund” and collectively, the “Funds”): Bond Debenture Portfolio (“Bond Debenture”), Calibrated Dividend Growth Portfolio (“Calibrated Dividend Growth”), Developing Growth Portfolio (“Developing Growth”), Fundamental Equity Portfolio (“Fundamental Equity”), Growth and Income Portfolio (“Growth and Income”), Growth Opportunities Portfolio (“Growth Opportunities”), Mid Cap Stock Portfolio (“Mid Cap Stock”), Short Duration Income Portfolio (“Short Duration Income”) and Total Return Portfolio (“Total Return”). Each Fund is diversified as defined in the Act.

2. SIGNIFICANT ACCOUNTING POLICIES

(a)	Investment Valuation-Under procedures approved by the Funds’ Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), the Funds’ 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 Funds 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. Each 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 quoted 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 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 may employ 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)	Fair Value Measurements-Fair value is defined as the price that each 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 each Fund’s own assumptions in determining the fair value of investments).

	A summary of inputs used in valuing each Fund’s investments and other financial instruments as of September 30, 2019 and, if applicable, Level 3 rollforwards for the period then ended is included in each 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. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. FEDERAL TAX INFORMATION

It is the policy of each 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.

Each 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 each Fund’s filed U.S. federal tax returns remains open generally three years after the filing of the tax return. The statutes of limitations on each Fund’s, state and local tax returns may remain open for an additional year depending upon the jurisdiction.
