<sup>(1)</sup> Refer to Note 2(a) for a description of fair value measurements and the three-tier hierarchy of inputs.

<sup>(2)</sup> 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. When applicable, each Level 3 security is identified on the Schedule of Investments along with the valuation technique utilized.

A reconciliation of Level 3 investments is presented when the Fund has a material amount of Level 3 investments at the beginning or end of the period in relation to the Fund's net assets. Management has determined not to provide a reconciliation and a summary of unobservable inputs as the balance of Level 3 investments was not considered to be material to the Fund's net assets at the beginning or end of the period.

<sup>(f)</sup> Level 3 Investment as described in Note 2(a) in the Notes to Schedule of Investments.

<sup>(h)</sup> Interest-only security. The principal amount shown is a notional amount representing the outstanding principal of the underlying debt obligation(s). Holders of interest-only securities do not receive principal payments on the underlying debt obligation(s).

<sup>(i)</sup> Interest rate is based on the weighted average interest rates of the underlying mortgages within the mortgage pool.

&nbsp;&nbsp;&nbsp;&nbsp;**1.** **ORGANIZATION** 

Lord Abbett Series Fund, Inc. (the "Company") is registered under the Investment Company Act of 1940, as amended (the "1940 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"), Developing Growth Portfolio ("Developing Growth"), Dividend Growth Portfolio ("Dividend 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 1940 Act. Bond Debenture Portfolio also invests in the Lord Abbett Private Credit Fund ("PCF"), which is a non-diversified, closed-end management investment company which elected to be regulated as a business development company under the 1940 Act.

&nbsp;&nbsp;&nbsp;&nbsp;**2.** **SIGNIFICANT ACCOUNTING POLICIES** 

---

| | |
|:---|:---|
| (a) | **Investment Valuation** **-**Under procedures approved by the Funds' Board of Directors (the "Board"), the Board has designated the determination of fair value of the Funds' portfolio investments to Lord, Abbett & Co. LLC ("Lord Abbett") as its valuation designee. Accordingly, Lord Abbett is responsible for, among other things, assessing and managing valuation risks, establishing, applying and testing fair value methodologies, and evaluating pricing services. Lord Abbett has formed a pricing committee (the "Pricing Committee") that performs these responsibilities on behalf of Lord Abbett, administers the pricing and valuation of portfolio investments and ensures that prices utilized reasonably reflect fair value. Among other things, these procedures allow Lord Abbett, subject to Board oversight, 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. When valuing foreign equity securities that meet certain criteria, the Pricing Committee uses a third-party fair valuation service that values such securities to reflect market trading that occurs after the close of the applicable foreign markets of comparable securities or other instruments that correlate to the fair-valued 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 ask prices. 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 ask prices is used. Investments in the PCF are valued at their net asset value ("NAV") each month end. 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. 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. |

---

**Notes to Schedule of Investments (unaudited)(continued)**

---

| |
|:---|
| Forward foreign currency exchange contracts are valued using daily forward exchange rates. Swaps, options and options on 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 observable inputs such as 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 periodically reviews reports that may include fair value determinations made by the Pricing Committee, related market activity, inputs and assumptions, and retrospective comparison of 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. Investments in open-end money market mutual funds are valued at their NAV as of the close of each business day. |
| **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: |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 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).

If applicable, a summary of inputs used in valuing each Fund's investments and other financial instruments as of March 31, 2026 and 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.

**Notes to Schedule of Investments (unaudited)(concluded)**

&nbsp;&nbsp;&nbsp;&nbsp;**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.

&nbsp;&nbsp;&nbsp;&nbsp;**4.** **SECURITIES LENDING AGREEMENT** 

The Funds have established a securities lending agreement with Citibank, N.A. for the lending of securities to qualified brokers in exchange for securities or cash collateral equal to at least the market value of securities loaned, plus interest, if applicable. Cash collateral is invested in an approved money market fund. In accordance with the Funds' securities lending agreement, the market value of securities on loan is determined each day at the close of business and any additional collateral required to cover the value of securities on loan is delivered to the Funds on the next business day. As with other extensions of credit, the Funds may experience a delay in the recovery of their securities or incur a loss should the borrower of the securities breach its agreement with the Funds or the borrower becomes insolvent at a time when the collateral is insufficient to cover the cost of repurchasing securities on loan.

The initial collateral received by the Funds is required to have a value equal to at least 100% of the market value of the securities loaned. The collateral must be marked-to-market daily to cover increases in the market value of the securities loaned (or potentially a decline in the value of the collateral). In general, the risk of borrower default will be borne by Citibank, N.A.; the Funds will bear the risk of loss with respect to the investment of the cash collateral. The advantage of such loans is that the Funds continue to receive income on loaned securities while receiving a portion of any securities lending fees and earning returns on the cash amounts which may be reinvested for the purchase of investments in securities.

As of March 31, 2026, the market value of securities loaned and collateral received were as follows:

---

| | | |
|:---|:---|:---|
| **Funds** | **Market Value of Securities Loaned** | **Collateral Received** |
| Bond Debenture Portfolio | $28409517 | $29347566 |
| Developing Growth Portfolio | 860269 | 813656 |
| Short Duration Income Portfolio | 101117 | 105019 |
| Total Return Portfolio | 784703 | 802926 |
