Strategy Narrative [Text Block]
Under normal circumstances, this Fund invests at least 80% of its assets in a combination of  (1) derivatives that provide exposure to bonds and (2) bonds.
Pacific Life Fund Advisors LLC (“PLFA”), the investment adviser of the Fund, and Fidelity Diversifying Solutions LLC (“FDS”), sub-adviser to a portion of the Fund, manage the Fund as described further below.
The term “bond” in the Fund’s name refers to debt securities and derivatives that provide exposure to debt securities.
PLFA and FDS normally invest the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at their investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by companies in the Financial sector.
PLFA managed portion:
For the PLFA managed portion of the Fund, PLFA seeks to gain exposure to debt securities using derivatives in a notional amount approximately equal to the Fund’s net assets. Because fewer assets are generally required to gain investment exposure using derivatives than with securities directly, PLFA allocates the remaining assets to FDS to manage as described under the “FDS managed portion.”
These derivatives are total return swap agreements and futures contracts. PLFA seeks to achieve the Fund’s investment goal in this portion of the Fund by gaining exposure to debt securities through total return swap agreements and futures contracts on the Bloomberg US Aggregate Bond Index (the “Index”), a debt securities index that represents the investment grade, U.S. dollar-denominated, fixed rate taxable bond market. PLFA may also enter into total return swap agreements on exchange traded funds (“ETFs”) that seek to track the performance of the Index.
Using derivatives such as total return swap agreements and futures contracts on the Index or total return swap agreements on ETFs that track the performance of the Index is a way to obtain investment exposure to debt securities, as represented by the Index, and seek the returns of the Index without purchasing all of the securities in the Index. PLFA may also invest in U.S. Treasury futures contracts to gain exposure to debt securities that approximate key risk factors and performance attributes of the Index, such as duration.
PLFA will also seek to achieve additional gains above the Index by making specific investment decisions for the Fund as it sees investment opportunities (“incremental alpha”). To seek incremental alpha, PLFA may use futures contracts and swap agreements (including total return swaps, interest rate swaps and credit default swaps) to implement its investment views on risk factors or performance attributes within the debt securities market, as represented by the Index. This could involve, for example, PLFA selling short U.S. Treasury futures contracts to express an investment view for lower duration relative to the Index, or doing the opposite.
FDS managed portion: 
FDS manages its portion of the Fund to seek to contribute to returns in excess of the Index returns (or “alpha”), to earn income to offset the cost of the Fund’s derivatives investments, and to maintain collateral for the Fund’s derivatives exposure.
This portion of the Fund will be invested primarily in investment grade debt securities, including U.S. debt and U.S. dollar-denominated debt issued by foreign entities in developed markets, and repurchase agreements for those securities. Under normal circumstances, this portion of the Fund is expected to maintain an average credit quality of A- or higher and a weighted average duration that is between 0 and 2.75 years. Duration is often used to measure a bond’s sensitivity to interest rates. The longer this portion of the Fund’s duration, the more sensitive it is to interest rate risk. The shorter this portion of the Fund’s duration, the less sensitive it is to interest rate risk.
When selecting investments for this portion of the Fund, FDS evaluates sectors of the bond market and individual securities within these sectors. FDS selects U.S. dollar-denominated bonds from several sectors including: U.S. and foreign developed market government securities (including agencies); investment grade corporate bonds; mortgage-related securities; asset-backed securities; and cash equivalents. 
In addition, FDS may use derivatives, including buying or selling options or futures contracts on a debt security or an index of debt securities, or entering into credit default swaps and interest rate swaps, including options thereon (i.e., swaptions), primarily to manage risks of the debt security investments by increasing or decreasing the exposure to risk factors associated with those investments or as a substitute for investing in the debt securities directly. For example, FDS could use Treasury futures contracts to manage interest rate risk or credit default swaps to manage credit risk of corporate bonds or gain exposure to debt security investments in a certain sector.
This portion of the Fund may also invest in debt securities issued pursuant to Rule 144A under the Securities Act of 1933 (“Rule 144A securities”).
FDS may purchase or sell investments for this portion of the Fund for a variety of reasons, such as to adjust the Fund’s average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.
This portion of the Fund may lend its portfolio holdings to certain financial institutions.

Strategy Narrative [Text Block]
This Fund invests principally in income producing debt instruments. Under normal circumstances, the Fund will invest at least 60% of its assets in investment grade debt instruments, including corporate debt securities, asset-backed securities, mortgage-related securities, U.S. government securities and agency securities. The Fund may invest up to 40% of its assets in non-investment grade (high yield/high risk, sometimes called “junk bonds”) debt instruments and floating rate senior loans. Debt instruments in which the Fund invests may include those denominated in U.S. dollars and issued by foreign entities in developed markets.
The Fund expects to maintain a weighted average duration within two years (plus or minus) of the Bloomberg US Aggregate Bond Index. Duration is often used to measure a bond’s sensitivity to interest rates. The longer a fund’s duration, the more sensitive it is to interest rate risk. The shorter a fund’s duration, the less sensitive it is to interest rate risk. As of December 31, 2024, the duration of the Bloomberg US Aggregate Bond Index was 6.04 years, and the duration of the Fund was 5.81 years.
Fundamental Research Process. Individual investment selection is based on the sub-adviser’s fundamental research process. The sub-adviser’s fundamental research process combines a bottom-up issuer analysis and top-down market assessment. A bottom-up issuer analysis relies upon the sub-adviser’s fundamental research analysis of individual issuers. A top-down market assessment provides a framework for portfolio risk positioning and sector allocations. Once this is determined, the sub-adviser looks for companies that it believes have sustainable competitive positions, strong management teams and the ability to repay or refinance its debt obligations. The sub-adviser performs a credit analysis on each potential issuer and a relative value analysis for each potential investment. When selecting investments, the sub-adviser may invest in instruments that it believes have the potential for capital appreciation.
An investment is generally sold when the issue has realized its price appreciation target, the issue no longer offers relative value, or an adverse change in corporate or sector fundamentals has occurred.
The Fund may lend its portfolio holdings to certain financial institutions.

Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]
Under normal circumstances, this Fund invests at least 80% of its assets in debt securities.
The Fund may invest in debt securities of any maturity and credit quality.
The Fund is divided into two portions, each of which is managed by a different portfolio management team at the Fund’s sub-adviser. Each team uses different investment strategies in seeking to achieve the investment goal of the Fund. Pacific Life Fund Advisors, LLC (“PLFA”) is the Fund’s investment adviser and selected these two strategies, the Core Plus Full Discretion and Core Plus Relative Return strategies, to be utilized by the Fund because of their different approaches to investing in fixed income. PLFA monitors the performance of each strategy on an ongoing basis. PLFA generally allocates the Fund’s assets equally between the two strategies but, subject to PLFA’s discretion, may change the allocation or rebalance as it deems appropriate to meet the Fund’s investment goal at any time without shareholder notice. PLFA allocates assets to each strategy in an effort to increase diversification among securities and investment strategies in seeking to increase the Fund’s potential for investment return while managing its risk and volatility. In addition, PLFA analyzes the risks arising from the investments of each strategy; evaluates the impact of any risk exposures on the Fund’s risk/return objectives; contemplates valuations, investor sentiment and other economic factors; and considers adjustments to strategy allocations as a result. The Fund may deviate from PLFA’s intended strategy allocation due to cash flows and changes to asset values.
The Fund may lend its portfolio holdings to certain financial institutions.
The two portions and their corresponding investment strategies are as follows:
Core Plus Full Discretion portion: This strategy employs an opportunistic style based on a bottom-up value-driven investment process combined with a macroeconomic and credit cycle perspective (the sub-adviser’s framework for identifying improving or deteriorating credit fundamentals). The strategy emphasizes a long-term view of market developments, with the intention to hold securities through a credit cycle as their fundamental credit characteristics improve. The strategy views the entire spectrum of fixed income markets as a global opportunity set from which to choose the most attractive total return opportunities, regardless of the sector.
Fixed income investments for this portion of the Fund may include securities issued by U.S. and foreign corporations and governments, bank loans and collateralized loan obligations (“CLOs”), commercial and residential mortgage-backed securities and other asset-backed securities, convertible securities, securities issued pursuant to Rule 144A under the Securities Act of 1933 (“Rule 144A securities”) and structured notes.
This portion of the Fund will normally invest at least 80% of its assets in investment grade fixed income investments and may invest up to 15% of its assets in fixed income securities that are rated non-investment grade (high yield/high risk, sometimes called “junk bonds”) or, if unrated, are of comparable quality as determined by the sub-adviser.
This portion of the Fund may invest up to 30% of its assets in foreign securities (including emerging markets securities), which includes up to 20% in foreign currency-denominated securities. This portion of the Fund may also invest in obligations of supranational entities without limit (supranational entities are entities designated or supported by national governments to promote economic reconstruction, development or trade amongst nations, such as the World Bank).
This portion of the Fund may use futures contracts, forward commitments and swaps (i.e., derivatives) for hedging and investment purposes.
This portion of the Fund expects to maintain a weighted average effective duration within five years (plus or minus) of the Fund’s benchmark index, the Bloomberg U.S. Aggregate Bond Index. Duration is often used to measure a bond’s sensitivity to interest rates. The longer a fund’s duration, the more sensitive it is to interest rate risk. The shorter a fund’s duration, the less sensitive it is to interest rate risk. As of December 31, 2024, the duration of the Bloomberg US Aggregate Bond Index was 6.04 years, the duration of this portion of the Fund was 6.20 years, and the duration of the Fund was 6.36 years.
When selecting securities to buy or sell for this portion of the Fund, the team considers the financial strength of the issuer, current interest rates, current valuations, the team’s expectations regarding future changes in interest rates and comparisons of the level of risk associated with particular investments with the team’s expectations concerning the potential return of those investments.
Core Plus Relative Return portion: This strategy focuses on the credit cycle as the primary driver of interest rates and credit spreads. The investment process primarily looks at macroeconomic factors in its analyses, and is designed to balance yield with capital preservation. The strategy will generally take on greater risk in stable and improving environments when credit valuations are considered to be undervalued, while emphasizing liquidity and quality through economic downturns. The strategy uses security selection based on fundamental, bottom-up credit analysis as an additional source of added value. The strategy is benchmark-aware, and seeks to outperform the Fund’s benchmark. The strategy also performs risk management analyses relative to the Fund’s benchmark to manage the volatility of this portion of the Fund. Traditional risk analytics (including tracking error) are complemented by forward-looking scenario analyses for a more comprehensive risk picture.
Fixed income investments for this portion of the Fund may include securities issued by U.S. and foreign corporations and governments, securities issued by supranational entities, U.S. government-sponsored agency debenture and pass-through securities, commercial mortgage-backed and other asset-backed securities, and inflation-linked securities. This portion of the Fund
may also invest in Rule 144A securities, structured notes, foreign securities (including those in emerging markets) and mortgage-related securities.
This portion of the Fund will normally invest at least 80% of its assets in investment-grade fixed income securities, and may invest up to 20% of its assets in securities that are rated non-investment grade (high yield/high risk, sometimes called “junk bonds”) or if unrated, are of comparable quality as determined by the sub-adviser. 
This portion of the Fund may use futures contracts, forward commitments and swaps (i.e., derivatives) for hedging and investment purposes.
This portion of the Fund expects to maintain a weighted average effective duration within two years (plus or minus) of the Fund’s benchmark index, the Bloomberg US Aggregate Bond Index. Duration is often used to measure a bond’s sensitivity to interest rates. The longer a fund’s duration, the more sensitive it is to interest rate risk. The shorter a fund’s duration, the less sensitive it is to interest rate risk. As of December 31, 2024, the duration of the Bloomberg US Aggregate Bond Index was 6.04 years, the duration of this portion of the Fund was 6.52 years, and the duration of the Fund was 6.36 years.
When selecting securities for this portion of the Fund, purchase and sale considerations by the team include overall portfolio yield, interest rate sensitivity across different maturities held, fixed-income sector fundamentals and outlook, technical supply/​demand factors, credit risk, cash flow variability, security-specific characteristics, as well as potential currency and liquidity risk. The team also considers economic factors. Individual securities are assessed on a risk/return basis, both on a benchmark-relative and on an absolute return basis, and on their fit within the overall strategy.
Floating Rate Income Portfolio | Floating Rate Income Portfolio  
Prospectus [Line Items]  
Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]
This Fund invests principally in income producing floating rate loans and floating rate debt securities. Under normal
circumstances, this Fund invests at least 80% of its assets in floating rate loans and floating rate debt securities. Floating rate loans and floating rate debt securities are those with interest rates which float, adjust or vary periodically based upon a benchmark indicator, a specified adjustment schedule or prevailing interest rates. Floating rate loans and floating rate debt securities in which the Fund invests consist of senior secured and unsecured floating rate loans, secured and unsecured second lien floating rate loans, and floating rate debt securities of domestic and foreign issuers. Senior floating rate loans and some floating rate debt securities are debt instruments that may have a right to payment that is senior to most other debts of the borrowers. Second lien loans are generally second in line in terms of repayment priority with respect to the pledged collateral. Borrowers may include corporations, partnerships and other entities that operate in a variety of industries and geographic regions. Generally, secured floating rate loans are secured by specific assets of the borrower.
Floating rate loans will generally be purchased from banks or other financial institutions through assignments or participations. A direct interest in a floating rate loan may be acquired directly from the agent of the lender or another lender by assignment or an indirect interest may be acquired as a participation in another lender’s portion of a floating rate loan.
The Fund is expected to invest substantially all of its assets in floating rate loans and other debt instruments that are rated non-investment grade or, if unrated, are of comparable quality as determined by the sub-adviser. The Fund may invest up to 20% of its assets in other types of debt instruments or securities including non-investment grade (high yield/high risk, sometimes called “junk bonds”) debt instruments.
The Fund may invest up to 25% of its assets in U.S. dollar-denominated foreign investments, principally in developed markets.
The sub-adviser normally invests the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at its investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Industrial sector.
Fundamental Research Process. Individual investment selection is based on the sub-adviser’s fundamental research process. The sub-adviser’s fundamental research process combines a bottom-up issuer analysis and top-down market assessment. A bottom-up issuer analysis relies upon the sub-adviser’s fundamental research analysis of individual issuers.

The sub-adviser performs a credit analysis on each potential issuer and a relative value analysis for each
potential investment. When selecting investments, the sub-adviser may invest in instruments that it believes have the potential for capital appreciation.

Strategy Narrative [Text Block]
Under normal circumstances, this Fund invests at least 80% of its assets in non-investment grade (high yield/high risk, sometimes
called “junk bonds”) debt instruments or in instruments with characteristics of non-investment grade debt instruments. The Fund principally invests in instruments that have intermediate to long term to maturity which generally means holdings with final maturities greater than one year. Securities include bonds and notes, which are given a low credit rating, or if unrated are of comparable quality as determined by the sub-adviser, including those of foreign issuers which are denominated in U.S. dollars. Bonds are given a credit rating based on the issuer’s ability to pay the quoted interest rate and maturity value on time. This may give the Fund more credit risk than other bond funds but also gives it the potential for higher income than investment grade bonds.

Inflation Managed Portfolio | Inflation Managed Portfolio  
Prospectus [Line Items]  
Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]
This Fund invests its assets in debt securities. Normally, the Fund focuses on investment in or exposure to inflation-indexed debt securities. It is expected that the amount invested in or exposed to inflation-indexed debt securities (either through cash market purchases, forward commitments or other derivative instruments) normally will be equivalent to at least 80% of the Fund’s net assets. Inflation-indexed debt securities are debt securities whose principal value or coupon payments are periodically adjusted according to an inflation index. If the index measuring inflation falls, the principal value of inflation-indexed debt securities and/or interest payable on such securities tends to fall. Duration management is a fundamental part of the investment strategy for this Fund. Duration is often used to measure a bond’s sensitivity to interest rates. The longer a fund’s duration, the more sensitive it is to interest rate risk. The shorter a fund’s duration, the less sensitive it is to interest rate risk.
The Fund may also invest in debt securities issued by the U.S. government or its agencies and foreign governments in developed countries or their agencies; debt securities issued by U.S. and foreign companies in developed countries; mortgage-related securities; asset-backed securities; convertible securities; commercial paper and other money market instruments; and derivative instruments including forward commitments relating to the previously mentioned securities. The Fund may invest up to 30% of its assets in securities of developed market foreign issuers that are denominated in foreign currencies; however, the Fund will maintain no foreign currency exposure from these securities and currencies by hedging back any foreign currency-denominated investments into U.S. dollars through the use of foreign currency derivatives such as foreign currency futures, options and forward commitments. The Fund may invest beyond the above limit in U.S. dollar-denominated securities of developed market foreign issuers.
The factors that will most influence the Fund’s performance are actual and expected inflation rates, as well as changes in real and nominal interest rates. (A real interest rate is the nominal interest rate less expected inflation.) A decline in real and nominal interest rates may benefit Fund performance, as could an increase in the actual rate of inflation. Conversely, rising real and nominal interest rates, and a decline in actual inflation or expected inflation, may have a negative impact on Fund performance. Total return is made up of coupon income plus any gains or losses in the value of the Fund’s securities.
When selecting securities, the sub-adviser:
•
Decides what duration to maintain. Generally, the sub-adviser expects the Fund’s weighted average duration to be within approximately 3 years (plus or minus) of the duration of the Bloomberg US TIPS Index. As of December 31, 2024, the duration of the Bloomberg US Treasury Inflation Protected Securities (“TIPS”) Index was 6.54 years, and the duration of the Fund was 6.84 years.
​
•
Decides how to allocate among short, intermediate and long duration issues and how much should be invested in various types of instruments.
​
•
Chooses companies to invest in by carrying out a credit analysis of potential investments.
​
The sub-adviser frequently uses futures contracts, forward commitments, swaps and options contracts (i.e., derivatives). Futures contracts are purchased and sold to adjust interest rate exposure (duration) and/or as a substitute for the physical security. Interest rate swaps are used to adjust interest rate exposures and/or as a substitute for the physical security. Credit default swaps are used to manage default risk of an issuer and/or to gain exposure to a portion of the debt market or an individual issuer. Options are primarily purchased to manage interest rate and volatility exposures or are sold to generate income. The Fund may use foreign currency derivatives such as foreign currency futures, options and forward commitments to hedge against fluctuations in currency exchange rates with respect to investments in securities of foreign issuers.
The Fund is also expected to be invested substantially in forward commitments (i.e., securities that are purchased or sold with payment and delivery taking place in the future) on inflation-indexed bonds to gain exposure to the inflation-linked market. The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as sale-buybacks or dollar rolls).
In addition to the strategies described above, the Fund typically uses derivatives as part of a strategy designed to reduce exposure to other risks, and to satisfy issuer diversification requirements.
The sub-adviser may sell a holding when it fails to perform as expected or when other opportunities appear more attractive.
The Fund may lend its portfolio holdings to certain financial institutions.
Intermediate Bond Portfolio | Intermediate Bond Portfolio  
Prospectus [Line Items]  
Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]
Under normal circumstances, this Fund invests at least 80% of its assets in debt securities. These debt securities will be focused
on investment grade intermediate-term debt securities (5 to 10 years to maturity) in order for the Fund to maintain a dollar-weighted average maturity between 4 and 12 years, but may also be invested in long-term debt securities (over 10 years to maturity). These debt securities are comprised of corporate bonds issued by U.S. entities, U.S. treasury obligations and other U.S. government and agency securities, and asset-backed and mortgage-related securities. The Fund may invest a substantial portion of its assets in mortgage-related debt securities in the sub-adviser’s discretion.
The Fund may invest up to 15% of its assets in U.S. dollar-denominated debt securities issued by a foreign corporation or a U.S. affiliate of a foreign corporation or a foreign government or its agencies and instrumentalities. The Fund may focus its investments in one country, in one or more regions, or small groups of countries.
The sub-adviser buys and sells securities and investments for the Fund based on its view of individual securities and market sectors. Taking a long-term approach, the sub-adviser looks for individual fixed income investments that it believes will perform well over a market cycle. The sub-adviser is value oriented and makes decisions to purchase and sell individual securities and instruments after performing a risk/reward analysis that includes an evaluation of interest rate risk, credit risk, duration, liquidity, legal provisions in offering documents (like term to maturity) of the debt security or instrument and the legal structure (such as priority of payments in a multi-class structure) of the debt security.
The Fund may lend its portfolio holdings to certain financial institutions.
Short Duration Bond Portfolio | Short Duration Bond Portfolio  
Prospectus [Line Items]  
Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]
Under normal circumstances, this Fund invests at least 80% of its assets in debt securities (including derivatives on such securities). Normally the Fund will focus on high quality, investment grade securities. Generally, the sub-adviser expects to track the duration of the Bloomberg US 1-3 Year Government/Credit Bond Index (plus or minus a half-year), although the securities held may have short, intermediate, and long terms to maturity (the period of time until final payment is due). As of December 31, 2024, the duration of the Bloomberg US 1-3 Year Government/​Credit Bond Index was 1.77 years, and the duration of the Fund was 1.89 years. Duration is often used to measure a bond’s sensitivity to interest rates. The longer a fund’s duration, the more sensitive it is to interest rate risk. The shorter a fund’s duration, the less sensitive it is to interest rate risk. In addition to making active sector allocation and security selection decisions, the sub-adviser also monitors Fund duration as part of its management of this Fund. The Fund’s average effective maturity will normally not exceed 3 years.
The sub-adviser intends to invest principally in U.S. government and agency securities, mortgage-related securities, asset-backed securities, corporate debt securities and derivatives thereof, money market instruments, and repurchase agreements collateralized by U.S. government securities. The Fund may invest up to 25% of its assets in foreign debt denominated in U.S. dollars.
Within this broad structure, investment decisions reflect the sub-adviser’s outlook for interest rates and the economy as well as the prices, yields, and credit quality of the various securities.
The sub-adviser uses futures contracts and swaps (i.e., derivatives). Futures contracts are purchased and sold to adjust interest rate exposure (duration) and/or as a substitute for the physical security. Foreign currency futures contracts are sold to hedge against currency fluctuations. Credit default swaps are used to protect the value of certain portfolio holdings or to manage the Fund’s overall exposure to changes in credit quality.
The sub-adviser may sell holdings for a variety of reasons, such as to adjust the Fund’s average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.
The Fund may lend its portfolio holdings to certain financial institutions.
Total Return Portfolio | Total Return Portfolio

Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]
Under normal circumstances, this Fund invests at least 80% of its assets in debt instruments, including instruments with characteristics of debt instruments (such as derivatives). The debt instruments in which the Fund principally invests are investment grade debt securities with varying terms to maturity (the period of time until final payment is due). The debt instruments in which the Fund invests include those issued by the U.S. government or its agencies; mortgage-related securities; asset-backed securities; commercial paper and other money market instruments; debt securities issued by foreign governments in developed countries or their agencies; debt securities issued by U.S. and foreign companies in developed countries; and convertible securities and inflation-indexed debt securities.
The Fund may invest up to 20% of its assets in securities of developed market foreign issuers that are denominated in foreign currencies, although the Fund will normally limit its foreign currency exposure from these foreign currency-denominated securities and currencies to 10% of its assets. To maintain this 10% limit, the sub-adviser will hedge back any foreign currency-denominated investments exceeding this 10% limit into U.S. dollars by using foreign currency derivatives such as foreign currency futures, options and forward commitments. The Fund may invest beyond the above limits in U.S. dollar-denominated securities of developed market foreign issuers.
Duration management is a fundamental part of the management strategy for this Fund. Duration is often used to measure a bond’s sensitivity to interest rates. The longer a fund’s duration, the more sensitive it is to interest rate risk. The shorter a fund’s duration, the less sensitive it is to interest rate risk.
When selecting securities, the sub-adviser:
•
Decides what duration to maintain. Generally, the sub-adviser expects the Fund’s weighted average duration to be within approximately 2 years (plus or minus) of the duration of the Bloomberg US Aggregate Bond Index. As of December 31, 2024, the duration of the Bloomberg US Aggregate Bond Index was 6.04 years, and the duration of the Fund was 6.67 years.
​
•
Decides how to allocate among short, intermediate and long duration issues and how much should be invested in various types of instruments.
​
•
Chooses companies to invest in by carrying out a credit analysis of potential investments.
​
The sub-adviser may also invest in derivatives based on debt securities and frequently uses futures contracts, forward commitments, swaps and options contracts (i.e., derivatives). Futures contracts are purchased and sold to adjust interest rate exposure (duration) and/or as a substitute for the physical security.
Foreign currency futures contracts, forward commitments or options are purchased or sold to gain or increase exposure to various currency markets and/or to hedge against currency fluctuations. Interest rate swaps are used to adjust interest rate exposures and/or as a substitute for the physical security. Credit default swaps are used to manage default risk of an issuer and/or to gain exposure to a portion of the debt market or an individual issuer. Options are primarily purchased to manage interest rate and volatility exposures or are sold to generate income.
The sub-adviser may invest in forward commitments (i.e., securities that are purchased or sold with payment and delivery taking place in the future), such as when issued securities, and mortgage TBA (“to be announced”) transactions, which are purchased to gain exposure to the mortgage market. The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as sale-buybacks or dollar rolls).
The sub-adviser may sell a holding when it fails to perform as expected or when other opportunities appear more attractive.
The Fund may lend its portfolio holdings to certain financial institutions.
Emerging Markets Debt Portfolio | Emerging Markets Debt Portfolio  
Prospectus [Line Items]  
Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]
Under normal circumstances, this Fund invests at least 80% of its assets in debt instruments that are economically tied to emerging market countries, which may be represented by instruments such as derivatives. These instruments may be issued by governments (sovereigns), government-guaranteed or majority government-owned entities (quasi-sovereigns), government agencies and instrumentalities and corporate issuers and may be denominated in any currency, including the local currency of the issuer.
The sub-adviser considers emerging market countries for debt purposes to include any country excluding the following developed market countries: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, United Kingdom and United States.
The Fund may invest up to 25% of its assets in issuers that are economically tied to any one emerging market country. The Fund may invest a relatively high percentage of its assets in securities of issuers in a small number of countries or a particular geographic region. However, under normal market conditions, the Fund generally expects to invest in a number of different foreign countries. The Fund considers emerging markets to include frontier markets, which for the purpose of this Fund are considered countries whose markets are in the earlier stage of development and have not yet reached the level of development to be considered an emerging market country.
Duration is often used to measure a bond’s sensitivity to interest rates. The longer a fund’s duration, the more sensitive it is to interest rate risk. The shorter a fund’s duration, the less sensitive it is to interest rate risk. When selecting investments, the sub-adviser decides what duration to maintain. The Fund will normally maintain a weighted average duration of between 2 and 10 years.
The Fund may invest in debt instruments of any credit quality, including, without limit, non-investment grade (high yield/high risk, sometimes called “junk bonds”). The sub-adviser may use forward commitments, options, swaps and futures contracts. Forward commitments, options, swaps and futures contracts may be purchased or sold to gain or increase exposure to various markets, to shift currency exposure from one country to another, for efficient portfolio management purposes and/or to hedge against market fluctuations. These derivatives may also be used to attempt to reduce certain risks, hedge existing positions, adjust certain characteristics of the Fund and gain exposure to particular assets as a substitute for direct investment in the assets.
In selecting investments for the Fund, the sub-adviser follows a portfolio construction process, blending both technical and fundamental considerations. The investment philosophy focuses on total return, is not managed in reference to a benchmark, and invests with an intent to limit potential capital loss through active portfolio management, including asset allocation, credit selection and issuer diversification, and attempts to deliver a superior return adjusted for a minimal level of volatility through the whole market cycle.
The sub-adviser may sell a holding when it fails to perform as expected or when other opportunities appear more attractive.
The Fund may lend its portfolio holdings to certain financial institutions.

Under normal circumstances, this Fund invests at least 80% of its assets in equity securities of companies included in the Fund’s applicable benchmark index, including instruments representative of that index (such as derivatives). The securities in the Fund’s applicable benchmark are those that are included in the S&P 500 Index. The S&P 500 Index is an index of the stocks of approximately 500 large-capitalization companies traded in U.S. stock markets. As of December 31, 2024, the market capitalization range of the S&P 500 Index was approximately $6.1 billion to $3.8 trillion. The Fund principally invests in common stock.
The Fund will generally hold substantially all of the stocks in the index in approximately the same proportions as their weightings in the index. The Fund will not concentrate, except to the same approximate extent as its index may concentrate, in the securities of a particular industry or group of industries (also known as a sector). As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Technology sector. The weightings of the Fund are likely to change over time as the composition of the index changes over time.
The Fund will not deviate from the above noted strategies at any time for any reason. The Fund may become non-diversified, as defined under the Investment Company Act of 1940, as amended (the “1940 Act”), solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the index.
The Fund may lend its portfolio holdings to certain financial institutions.

This Fund invests primarily in domestic and foreign equity securities (including common stock and warrants) selected for
their growth potential. The Fund may invest in companies of any capitalization size, from larger, well-established companies to smaller, emerging growth companies. The Fund normally focuses its investments in a core group of common stocks of companies which are prominent within their industry and which the sub-adviser believes have competitive advantages. As such, the Fund may invest in a smaller number of holdings.
The sub-adviser normally invests the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at its investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Technology sector and Communications sector.
The sub-adviser applies a “bottom up” approach in choosing investments in which it looks for companies with earnings growth potential that may not be recognized by the market at large.
The Fund invests in foreign securities, including in emerging market countries, that are either U.S. dollar or foreign currency-denominated.

Strategy [Heading] Principal Investment Strategies
Strategy Narrative [Text Block]
The Fund seeks to provide capital appreciation through participation in the broad equity markets while hedging overall market exposure relative to traditional long-only equity strategies.
Under normal circumstances, the Fund invests at least 80% of its assets in equity securities. The Fund uses an enhanced index strategy to invest in these equity securities, which primarily consist of common stocks of large capitalization U.S. companies with market capitalizations similar to those within the universe of the S&P 500 Index. Under an enhanced index strategy, not all of the stocks in the S&P 500 Index, the Fund’s primary benchmark, are included in the Fund, and the Fund’s position in an individual stock may be overweighted or underweighted when compared to the index. Sector by sector, the Fund’s weightings are similar to those of the S&P 500 Index. Within each sector, however, the Fund modestly overweights equity securities that it considers undervalued or fairly valued while modestly underweighting or not holding equity securities that appear overvalued.
The sub-adviser normally invests the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at its investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Technology sector.
The Fund will also systematically purchase and sell exchange traded put options and sell exchange traded call options, employing an option overlay known as a “Put/Spread Collar” strategy. The options may be based on the S&P 500 Index or on exchange-traded funds (“ETFs”) that replicate the S&P 500 Index (“S&P 500 ETFs”). The combination of the diversified portfolio of equity securities, the downside protection from the index put options and the income from the index call options is intended to provide the Fund with a portion of the returns associated with equity market investments while exposing investors to less risk than traditional long-only equity strategies. Specifically, the Fund seeks to provide a competitive risk adjusted return over a full market cycle (defined as three to five years) relative to the S&P 500 Index with lower volatility than traditional long-only equity strategies.
The Fund’s options overlay strategy is intended to provide the Fund with downside protection, while foregoing some upside potential. A put option spread seeks to protect the Fund against a decline in price, but only to the extent of the difference between the strike prices of the put option purchased and the put option sold. Entering into put option spreads is typically less expensive than a strategy of only purchasing put options and may benefit the Fund in a flat to upwardly moving market by reducing the cost of the downside protection; the downside protection of the put option spread, however, is limited as compared to just owning a put option. The put option spreads are intended to protect the Fund from market losses of between -5% and -20% (measured by the Fund’s benchmark) on a quarterly basis, meaning that the Fund will generally participate in a loss between 0% and -5% over that quarter if the market decreases to those respective percentages.
The Fund is expected to be protected from losses between -5% and -20%. However, if the market generally moves down below 20%, the Fund would generally participate in the loss of the first 5% plus any loss after the 20% loss in the market. For example, if over a quarter the market (measured by the Fund’s benchmark) were to decrease 25%, the Fund would generally participate in a 10% loss. The sub-adviser intends to maintain this level of downside protection for the Fund on a quarter to quarter basis. The premiums received from selling index call options are intended to substantially offset the cost of the put option spread, but selling the call options also reduces the Fund’s ability to profit from increases in the value of its equity portfolio because in rising markets the call option will cap the upside potential once the market price rises to the option’s strike price. In rising markets, the Fund’s total returns are generally expected to be capped between 3.5% and 5.5% over a quarter (inclusive of dividend). Conditions may vary that could alter this cap. For example, the cap would likely be lower in lower volatility environments and higher in higher volatility environments, reflecting the market pricing of the call options. In addition, the Fund’s actual returns may be higher or lower than the above ranges based on the performance of the Fund’s portfolio of equity securities relative to its benchmark. While the Fund typically constructs the Put/Spread Collar utilizing index options, it may also hedge the position with the use of a short position in S&P 500 Index futures or S&P 500 ETFs.
In addition to the use of the Put/Spread Collar strategy described above, the Fund may use future contracts, primarily futures on indexes, to more effectively gain targeted equity exposure from its cash positions and to hedge the Fund’s portfolio if it is unable to purchase or write the necessary options for its overlay strategy.
There are no assurances that the Fund will successfully implement these hedging strategies; actual returns may vary substantially.
Investment Process — Enhanced Index:
To implement the enhanced index strategy, the sub-adviser employs a three-step process that combines research, valuation and stock selection. The sub-adviser takes an in-depth look at company prospects, which is designed to provide insight into a company’s real growth potential. The research findings allow the sub-adviser to rank the companies in each sector group according to their relative value.
The sub-adviser then buys and sells equity securities for the Fund using the research and valuation rankings as a basis. In general, the sub-adviser buys equity securities that are identified as attractive and considers selling them when they appear less attractive based on the Fund’s process. Along with attractive valuation, the sub-adviser often considers a number of other criteria:
•
catalysts that could trigger a rise in a stock’s price
​
•
impact on the overall risk of the portfolio relative to the S&P 500 Index
​
•
high perceived potential reward compared to perceived potential risk
​
•
possible temporary mispricings caused by apparent market overreactions.
​
Investment Process — Options Overlay Strategy:
To implement the Put/Spread Collar strategy, the sub-adviser utilizes exchange traded equity options based either on the S&P 500 Index or on S&P 500 ETFs. The Put/Spread Collar is constructed by buying a put option at a higher strike price while writing a put option at a relatively lower strike price and simultaneously selling a call option that substantially offsets the cost of the put option spread. The Put/Spread Collar strategy is an actively managed process and is designed to provide a continuous market hedge for the portfolio.

Under normal circumstances, this Fund invests at least 80% of its assets in a combination of  (1) derivatives that provide exposure to the U.S. large-capitalization equity market and (2) bonds.
Pacific Life Fund Advisors LLC (“PLFA”), the investment adviser of the Fund, manages the large-cap portion of the Fund while Fidelity Diversifying Solutions LLC (“FDS”) manages the bond portion of the Fund as sub-adviser to that portion of the Fund.
PLFA and FDS normally invest the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at their investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by companies in the Financial sector.
Large-Cap portion:
The term “large-cap” in the Fund’s name refers to derivative investments used to gain exposure to the U.S. large-capitalization equity market.
For the large-cap portion of the Fund, PLFA seeks to gain exposure to the U.S. large-capitalization equity market using derivatives in a notional amount approximately equal to the Fund’s net assets. Because fewer assets are generally required to gain investment exposure using derivatives than with securities directly, PLFA allocates the remaining assets to the bond portion of the Fund.
These derivatives are total return swap agreements and futures contracts. PLFA seeks to achieve the Fund’s investment goal in this portion of the Fund by gaining exposure to the U.S. large-capitalization equity market through total return swap agreements and futures contracts on the S&P 500 Index (the “Index”), an equity securities index that represents the U.S. large-capitalization equity market.
PLFA generally considers a company to have a large market capitalization or to be a large-cap company if the company has a market capitalization within the range of companies included in the Index, or a comparable index which is generally considered in the financial services industry as representing the large-capitalization segment of the U.S. equity universe. As of December 31, 2024, the market capitalization range of the Index was approximately $6.1 billion to $3.8 trillion.
In seeking to gain exposure to the Index through the use of derivatives, this portion of the Fund will in turn be exposed to the same groups of industries/sectors in the same manner as the
Index, which may include a significant percentage to a single sector. Based upon the composition of the Index as of December 31, 2024, this portion of the Fund will likely be significantly represented by securities of companies in the Technology sector. The exposure of this portion of the Fund to sectors is likely to change over time as the composition of the Index changes over time.
This portion of the Fund will not concentrate, except to the same approximate extent as the Index may concentrate, in the securities of a particular industry or group of industries (also known as a sector). This portion of the Fund may become non-diversified, as defined under the Investment Company Act of 1940, as amended (the “1940 Act”), solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Index.
This portion of the Fund may also invest in futures contracts on other U.S. large-cap indices to gain exposure to the U.S. large-capitalization equity market. Using derivatives such as total return swap agreements and futures contracts is a way to obtain investment exposure to the U.S. large-capitalization equity market, as represented by the particular index, and seek the returns of that index without purchasing all of the securities in the index.
PLFA will also seek to achieve additional gains above the Index by making specific investment decisions for the Fund as it sees investment opportunities (“incremental alpha”). To seek incremental alpha, PLFA may use total return swap agreements and/or futures contracts to implement its investment views on sub-asset classes within the overall U.S. large-capitalization equity market, such as large-cap growth or large-cap value. This could involve, for example, buying total return swap agreements on a large-cap growth index to express a positive view on large-cap growth as a sub-asset class. Another example could be hedging out part of the large-cap growth portion of the Index using derivatives, resulting in an overweight to the large-cap value portion, or doing the opposite.
Bond portion: 
The term “bond” in the Fund’s name refers to debt securities and derivatives that provide exposure to debt securities.
The bond portion of the Fund will be managed by FDS to seek to contribute to returns in excess of the Index returns (or “alpha”), to earn income to offset the cost of the Fund’s derivatives investments, and to maintain collateral for the Fund’s derivatives exposure.
This portion of the Fund will be invested primarily in investment grade debt securities, including U.S. debt and U.S. dollar-denominated debt issued by foreign entities in developed markets, and repurchase agreements for those securities. Under normal circumstances, this portion of the Fund is expected to maintain an average credit quality of A- or higher and a weighted average duration that is between 0 and 2.75 years. Duration is often used to measure a bond’s sensitivity to interest rates. The longer this portion of the Fund’s duration, the more sensitive it is to interest rate risk. The shorter this portion of the Fund’s duration, the less sensitive it is to interest rate risk.
When selecting investments for this portion of the Fund, FDS evaluates sectors of the bond market and individual securities within these sectors. FDS selects U.S. dollar-denominated bonds from several sectors including: U.S. and foreign developed market government securities (including agencies); investment grade corporate bonds; mortgage-related securities; asset-backed securities; and cash equivalents.
In addition, FDS may use derivatives, including buying or selling options or futures contracts on a debt security or an index of debt securities, or entering into credit default swaps and interest rate swaps, including options thereon (i.e., swaptions), primarily to manage risks of the debt security investments by increasing or decreasing the exposure to risk factors associated with those investments or as a substitute for investing in the debt securities directly. For example, FDS could use U.S. Treasury futures contracts to manage interest rate risk or credit default swaps to manage credit risk of corporate bonds or gain exposure to debt security investments in a certain sector.
This portion of the Fund may also invest in debt securities issued pursuant to Rule 144A under the Securities Act of 1933 (“Rule 144A securities”).
FDS may purchase or sell investments for this portion of the Fund for a variety of reasons, such as to adjust the Fund’s average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.
This portion of the Fund may lend its portfolio holdings to certain financial institutions.

Under normal circumstances, this Fund invests at least 80% of its assets in securities of companies with medium market capitalizations. The Fund invests primarily in the common stock of domestic, mid-capitalization (“mid-cap”) companies that the sub-adviser believes offer superior growth prospects.
The sub-adviser generally considers a company to be a mid-cap company if the company has a market capitalization within the range of companies included in the Russell Midcap Growth Index, an index that measures the performance of those companies with higher price-to-book ratios and higher forecasted growth values within the mid-cap segment of the U.S. equity universe. As of December 31, 2024, the market capitalization range for the Russell Midcap Growth Index was approximately $1.7 billion to $168.4 billion. As of December 31, 2024, the weighted average market capitalization of the Fund was approximately $22.1 billion.
The sub-adviser selects most investments from companies included in the Russell Midcap Growth Index.
The sub-adviser implements the Fund’s strategy using a proprietary quantitative model that is designed to construct a portfolio driven by fundamental and technical stock selection variables. The portfolio managers play a role in building, utilizing, testing and modifying the financial algorithms and formulas used in the model.
The sub-adviser then reviews the proposed portfolio trades produced by the model in an effort to ensure that they are based on accurate and current information and, if necessary, makes adjustments to incorporate timely and accurate information prior to executing the trades.
The sub-adviser may sell securities for a variety of reasons, including: (i) identification of deteriorating stock selection factors; (ii) identification of replacement securities with higher perceived value; and (iii) compliance with the Fund’s investment goal, strategies, limitations and other parameters. For the avoidance of doubt, portfolio sell decisions are generally determined by the proprietary quantitative model, but such decisions can be made pursuant to input from the portfolio management team.

Under normal circumstances, this Fund invests at least 80% of its assets in equity securities of mid-capitalization companies. The
sub-adviser generally considers a company to be a mid-capitalization company if the company has a market capitalization within the range of companies included in the Russell Midcap Value Index, which measures the performance of the mid-capitalization value segment of the U.S. equity universe. As of December 31, 2024, the market capitalization range for the Russell Midcap Value Index was approximately $351.6 million to $75.2 billion. As of December 31, 2024, the weighted average market capitalization of the Fund was approximately $24.5 billion.
Under normal market conditions, the Fund invests primarily in common stock of U.S. companies that the sub-adviser identifies as having value characteristics. The Fund may also invest up to 15% of its assets in equity securities of foreign issuers that are U.S. dollar-denominated, including American Depositary Receipts (“ADRs”).
The sub-adviser normally invests the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Financial sector.
In selecting investments for the Fund, the sub-adviser examines various factors in determining the value characteristics of an issuer, including price-to-book-value ratios and price-to-earnings ratios. The sub-adviser also selects securities for the Fund based on a continuous study of trends in industries and companies, including the anticipated stability of earnings.
The sub-adviser may sell a holding when it appreciates to a stated target, it fails to perform as expected or when other opportunities appear more attractive.
The Fund may lend its portfolio holdings to certain financial institutions.

Under normal circumstances, this Fund invests at least 80% of its assets in a combination of  (1) derivatives that provide exposure to the Nasdaq-100 Index® and/or the Nasdaq-100 Total Return® Index (the “Nasdaq-100 Indices”) and (2) bonds.
Pacific Life Fund Advisors LLC (“PLFA”), the investment adviser of the Fund, manages the “QQQ” portion of the Fund while Fidelity Diversifying Solutions LLC (“FDS”) manages the bond portion of the Fund as sub-adviser to that portion of the Fund.
PLFA and FDS normally invest the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at their investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by companies in the Financial sector.
QQQ portion:
The term “QQQ” in the Fund’s name refers to derivative investments used to gain exposure to the Nasdaq-100 Indices, large-cap growth equity indices designed to track the performance of 100 of the largest domestic and international non-financial companies listed on the Nasdaq Stock Market® based upon market capitalization.
For the QQQ portion of the Fund, PLFA seeks to gain exposure to the Nasdaq-100 Indices using derivatives in a notional amount approximately equal to the Fund’s net assets. Because fewer assets are generally required to gain investment exposure using derivatives than with securities directly, PLFA allocates the remaining assets to the bond portion of the Fund.
These derivatives are total return swap agreements and futures contracts. Using derivatives such as total return swap agreements and futures contracts is a way to obtain the return of the Nasdaq-100 Indices that is the economic equivalent of, but does not involve investing in, all of the securities in those indices.
In seeking to gain exposure to the Nasdaq-100 Indices through the use of derivatives, this portion of the Fund will in turn be exposed to the same groups of industries/sectors in the same manner as the Nasdaq-100 Indices, which may include a significant percentage to a single sector. Based upon the composition of the Nasdaq-100 Indices as of December 31, 2024, this portion of the Fund will likely be significantly represented by securities of companies in the Technology sector. The exposure of this portion of the Fund to sectors is likely to change over time as the composition of the Nasdaq-100 Indices changes over time.
This portion of the Fund will not concentrate, except to the same approximate extent as the Nasdaq-100 Indices may concentrate, in the securities of a particular industry or group of industries (also known as a sector). This portion of the Fund may become non-diversified, as defined under the Investment Company Act of 1940, as amended (the “1940 Act”), solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Nasdaq-100 Indices.
Bond portion: 
The term “bond” in the Fund’s name refers to debt securities and derivatives that provide exposure to debt securities.
The bond portion of the Fund will be managed by FDS to seek to contribute to returns in excess of the Nasdaq-100 Indices returns (or “alpha”), to earn income to offset the cost of the Fund’s derivatives investments, and to maintain collateral for the Fund’s derivatives exposure.
This portion of the Fund will be invested primarily in investment grade debt securities, including U.S. debt and U.S. dollar-denominated debt issued by foreign entities in developed markets, and repurchase agreements for those securities. Under normal circumstances, this portion of the Fund is expected to maintain an average credit quality of A- or higher and a weighted average duration that is between 0 and 2.75 years. Duration is often used to measure a bond’s sensitivity to interest rates. The longer this portion of the Fund’s duration, the more sensitive it is to interest rate risk. The shorter this portion of the Fund’s duration, the less sensitive it is to interest rate risk.
When selecting investments for this portion of the Fund, FDS evaluates sectors of the bond market and individual securities within these sectors. FDS selects U.S. dollar-denominated bonds from several sectors including: U.S. and foreign developed market government securities (including agencies); investment grade corporate bonds; mortgage-related securities; asset-backed securities; and cash equivalents. 
In addition, FDS may use derivatives, including buying or selling options or futures contracts on a debt security or an index of debt securities, or entering into credit default swaps and interest rate swaps, including options thereon (i.e., swaptions), primarily to manage risks of the debt security investments by increasing or decreasing the exposure to risk factors associated with those investments or as a substitute for investing in the debt securities directly. For example, FDS could use U.S. Treasury futures contracts to manage interest rate risk or credit default swaps to manage credit risk of corporate bonds or gain exposure to debt security investments in a certain sector.
This portion of the Fund may also invest in debt securities issued pursuant to Rule 144A under the Securities Act of 1933 (“Rule 144A securities”).
FDS may purchase or sell investments for this portion of the Fund for a variety of reasons, such as to adjust the Fund’s average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.

Under normal circumstances, the Fund invests at least 80% of its assets in securities of companies with small market capitalizations, including instruments with characteristics of small-capitalization equity securities (such as derivatives).
The Fund invests mainly in common stocks of small, publicly traded companies. As of December 31, 2024, the weighted average market capitalization of the Fund was approximately $3.6 billion.
This Fund is sub-advised by both Franklin Mutual Advisers, LLC (“Franklin”) and BlackRock Investment Management, LLC (“BlackRock”). Pacific Life Fund Advisors, LLC (“PLFA”) is the Fund’s investment adviser and, subject to the approval of the Trust’s board of trustees, selects the Fund’s sub-advisers and monitors their performance on an ongoing basis. PLFA has selected the Fund’s current sub-advisers because of their different approaches to investing in securities of companies with small market capitalizations. Franklin uses an active management style; BlackRock uses an index management style and seeks to track the performance of the Fund’s index. PLFA allocates the Fund’s assets between Franklin and BlackRock but subject to PLFA’s discretion may change the allocation or rebalance as it deems appropriate to meet the Fund’s investment goal at any time without shareholder notice. PLFA allocates assets to the sub-advisers to increase diversification among securities and investment styles in seeking to increase the Fund’s potential for investment return while managing its risk and volatility. In addition, PLFA analyzes the risks arising from the investments of each strategy; evaluates the impact of any risk exposures on the Fund’s risk/return objectives; contemplates valuations, investor sentiment and other economic factors; and considers adjustments to strategy allocations as a result. The Fund may deviate from PLFA’s intended strategy allocation due to cash flows and changes to asset values.
The sub-advisers normally invest the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at their investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Financial sector.
The Fund may lend its portfolio holdings to certain financial institutions.
Franklin managed portion: Franklin generally considers a company to be a small-capitalization company if it has a market capitalization that is no more than: (1) the largest market capitalization of a company in the Russell 2000 Index as of the most recent month end; or (2) the average of the month end largest market capitalization of a company in the Russell 2000 Index over the prior 12 months, whichever is greater. As of December 31, 2024, those capitalization amounts were (1) $14.7 billion and (2) $28.7 billion, respectively.
Franklin generally invests its portion of the Fund’s assets in common stocks that it believes are currently undervalued and have the potential for capital appreciation. In choosing investments that are undervalued, Franklin focuses on companies that have one or more of the following characteristics.
•
Stock prices that are low relative to current or historical or future earnings, book value, cash flow or sales — all relative to the market, a company’s industry or a company’s earnings history.
​
•
Recent sharp price declines but the potential for good long-term earnings prospects, in the sub-adviser’s opinion.
​
•
Valuable intangibles not reflected in the stock price, such as franchises, distribution networks or market share for particular products or services, underused or understated assets or cash, or patents and trademarks.
​
In addition to price, Franklin, in choosing an investment, may consider a variety of other factors that may identify the issuer as a potential turnaround candidate or takeover target, such as ownership of valuable franchises, trademarks or trade names, control of distribution networks and market share for particular products. Purchase decisions may also be influenced by income, company buy-backs, and insider purchases and sales. Environmental, social and governance (“ESG”) related assessments of companies may also be considered. Franklin does not assess every investment for ESG factors and, when it does, not every ESG factor may be identified or evaluated.
Franklin employs a bottom-up stock selection process.
Franklin may invest up to 25% of its portion of the Fund’s assets in securities of foreign issuers, including American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”), and Global Depositary Receipts (“GDRs”), that may be U.S. dollar or foreign currency-denominated.
Franklin may sell a holding when it appreciates to a stated target, it fails to perform as expected or when other opportunities appear more attractive.
BlackRock managed portion: BlackRock generally considers a company to be a small-capitalization company if the company has a market capitalization within the range of companies included in the Russell 2000 Value Index, which measures the performance of the small-capitalization value segment of the U.S. equity universe. It includes those Russell 2000 Index companies with lower price-to-book ratios and lower forecasted growth values. As of December 31, 2024, the market capitalization range of the Russell 2000 Value Index was approximately $6.1 million to $13.2 billion. This portion of the Fund principally invests in common stock.
This portion of the Fund will generally hold substantially all of the stocks in the index in approximately the same proportions as their weightings in the index. The sub-adviser will utilize a sampling approach to seek to replicate the performance of the Russell 2000 Value Index by investing in a portfolio of securities in the Russell 2000 Value Index that collectively has an investment profile similar to that of the Russell 2000 Value Index. The sampling approach may result in a small part of this portion of the Fund being invested in certain stocks in proportions that are not approximately the same as their index weightings, but which are expected to result in a portfolio that has, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Fund’s index. This portion of the Fund will not concentrate, except to the same approximate extent as the Fund’s applicable benchmark index may concentrate, in the securities of a particular industry or group of industries (also known as a sector).
This portion of the Fund will not deviate from the above noted strategies at any time for any reason.

As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Consumer Non-Cyclical sector.
The sub-adviser focuses on investing the Fund’s assets in the stocks of companies it believes to have above average earnings growth potential compared to other companies (growth companies). Growth companies tend to have stock prices that are high relative to their earnings, dividends, book value, or other financial measures.
The Fund may invest in equity securities and depositary receipts of foreign companies that are U.S. dollar or foreign currency-denominated.
The sub-adviser uses an active bottom-up investment approach to buying and selling investments for the Fund. Investments are selected primarily based on fundamental analysis of individual issuers and their potential in light of their financial condition, and market, economic, political, and regulatory conditions. Factors considered may include analysis of an issuer’s earnings, cash flows, competitive position, and management ability. Quantitative screening tools that systematically evaluate issuers may also be considered.

Pacific Life Fund Advisors LLC (“PLFA”), the investment adviser of the Fund, manages the small-cap portion of the Fund while Fidelity Diversifying Solutions LLC (“FDS”) manages the bond portion of the Fund as sub-adviser to that portion of the Fund.
PLFA and FDS normally invest the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at their investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by companies in the Financial sector.
Small-Cap portion:
The term “small-cap” in the Fund’s name refers to derivative investments used to gain exposure to the U.S. small-capitalization equity market.
For the small-cap portion of the Fund, PLFA seeks to gain exposure to the U.S. small-capitalization equity market using derivatives in a notional amount approximately equal to the Fund’s net assets. Because fewer assets are generally required to gain investment exposure using derivatives than with securities directly, PLFA allocates the remaining assets to the bond portion of the Fund.
These derivatives are total return swap agreements and futures contracts. PLFA seeks to achieve the Fund’s investment goal in this portion of the Fund by gaining exposure to the U.S. small-capitalization equity market through total return swap agreements and futures contracts on the Russell 2000 Index (the “Index”), an equity securities index that represents the U.S. small-capitalization equity market.
PLFA generally considers a company to have a small market capitalization or to be a small-cap company if the company has a market capitalization within the range of companies included in the Index, or a comparable index which is generally considered in the financial services industry as representing the small-capitalization segment of the U.S. equity universe. As of December 31, 2024, the market capitalization range of the Index was approximately $6.1 million to $14.7 billion.
This portion of the Fund may also invest in futures contracts on other U.S. small-cap indices to gain exposure to the U.S. small-capitalization equity market. Using derivatives such as total
return swap agreements and futures contracts is a way to obtain investment exposure to the U.S. small-capitalization equity market, as represented by the particular index, and seek the returns of that index without purchasing all of the securities in the index.
PLFA will also seek to achieve additional gains above the Index by making specific investment decisions for the Fund as it sees investment opportunities (“incremental alpha”). To seek incremental alpha, PLFA may use total return swap agreements and/or futures contracts to implement its investment views on sub-asset classes within the overall U.S. small-capitalization equity market, such as small-cap growth or small-cap value. This could involve, for example, buying total return swap agreements on a small-cap growth index to express a positive view on small-cap growth as a sub-asset class. Another example could be hedging out part of the small-cap growth portion of the Index using derivatives, resulting in an overweight to the small-cap value portion, or doing the opposite.
Bond portion: 
The term “bond” in the Fund’s name refers to debt securities and derivatives that provide exposure to debt securities.
The bond portion of the Fund will be managed by FDS to seek to contribute to returns in excess of the Index returns (or “alpha”), to earn income to offset the cost of the Fund’s derivatives investments, and to maintain collateral for the Fund’s derivatives exposure.
This portion of the Fund will be invested primarily in investment grade debt securities, including U.S. debt and U.S. dollar-denominated debt issued by foreign entities in developed markets, and repurchase agreements for those securities.

Under normal circumstances, the Fund invests at least 80% of its assets in small-capitalization equity securities. The sub-adviser generally considers the following to be small-capitalization companies: (i) companies smaller than the largest 1,000 U.S. companies; (ii) companies representing the bottom 10% of the market capitalization of all U.S. listed companies; and (iii) companies in the Russell 2000 Value Index, which measures the performance of the small-capitalization value segment of the U.S. equity universe. As of December 31, 2024, the market capitalization range of the Russell 2000 Value Index was approximately $6.1 million to $13.2 billion. As of December 31, 2024, the weighted average market capitalization of the Fund was approximately $3.3 billion.
The sub-adviser normally invests the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Financial sector.
The Fund normally invests primarily in the common stock of companies located in the United States. To determine whether a company is a U.S. company, the sub-adviser will consider various factors, including where the company is headquartered, where the company’s principal operations are located, where a majority of the company’s revenues are derived, where the principal trading market is located, the country in which the company was legally organized, and whether the company is in the Russell 2000 Value Index.
In buying and selling securities for the Fund, the sub-adviser uses fundamental analysis of factors such as each issuer’s financial condition and industry position, as well as market and economic conditions. In selecting investments for the Fund, the sub-adviser seeks securities of small-capitalization companies with higher profitability and value characteristics. The sub-adviser defines “profitability” mainly as adjusted cash from operations to book value ratio (though other ratios may be considered). The sub-adviser defines “value characteristics” of an issuer mainly using adjusted book/price ratios (though other price to fundamental ratios may be considered).

Under normal circumstances, this Fund invests at least 80% of its assets in common stock. The sub-adviser focuses primarily on large-capitalization companies, emphasizing a value style of investing. The sub-adviser generally considers a company to be a large-capitalization company if the company has a market capitalization within the range of companies included in the Russell 1000 Value Index, which measures the performance of the large-capitalization value segment of the U.S. equity universe. As of December 31, 2024, the market capitalization range of the Russell 1000 Value Index was approximately $351.6 million to $977.5 billion. As of December 31, 2024, the weighted average market capitalization of the Fund was approximately $260.4 billion.
The Fund may also invest in the equity securities of companies with medium market capitalizations (“mid-capitalization companies”).
In selecting investments for the Fund, the sub-adviser looks for companies whose stock price it believes may not adequately reflect the company’s value. The sub-adviser attempts to purchase the stocks of these undervalued companies and hold each stock until the price has increased to, or is higher than, a level the sub-adviser believes more accurately reflects the fair value of the company. The sub-adviser uses a variety of analytical research tools and techniques to help it make decisions about buying or holding securities of companies that meet its investment criteria and selling the securities of companies that do not.
The sub-adviser normally invests the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at its investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Consumer Non-Cyclical sector.

The sub-adviser may sell a security for several reasons. A security may be sold due to a change in the company’s fundamentals or if the sub-adviser believes the security is no longer attractively valued.

Under normal circumstances, this Fund invests at least 80% of its assets in securities (including American Depositary Receipts (“ADRs”)) of companies whose principal activities are conducted in countries that are generally regarded as emerging market countries.
Companies whose principal activities are conducted in emerging market countries include issuers deemed to be economically tied to an emerging market country. The term “emerging markets” in the Fund’s name refers to those countries that are included in the MSCI Emerging Markets Index, an index that is designed to measure equity market performance of securities in emerging markets, and countries that are classified as an emerging market by MSCI, the World Bank, the International Finance Corporation or the United Nations and its agencies. Emerging market countries are typically less developed economically than industrialized countries and may offer high growth potential as well as considerable investment risk.
The Fund principally invests in common stock and other equity securities. The Fund may invest in companies of all market capitalization sizes as well as both growth and value stocks. The Fund may invest a relatively high percentage of its assets in securities of issuers in a single country, such as China, a small number of countries, or a particular geographic region. However, under normal market conditions, the Fund generally expects to maintain investments in at least six emerging market countries.
The sub-adviser normally invests the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at its investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Technology sector.
The sub-adviser uses both a bottom-up stock selection strategy and a top-down country selection strategy to manage the investments of the Fund.
The sub-adviser uses a quantitative style of management which utilizes proprietary models and market data and research, in combination with a qualitative overlay which incorporates the sub-adviser’s judgment and other non-quantifiable information into the investment process. The sub-adviser’s style of management overall emphasizes fundamentally-based stock and country selection, portfolio construction and implementation. The Fund’s investments are selected by the sub-adviser using fundamental research and a variety of quantitative techniques based on certain investment themes, including Fundamental Mispricings, High Quality Business Models, Sentiment Analysis and Market Themes & Trends, as follows:
•
Fundamental Mispricings seeks to identify high-quality businesses trading at a fair price, which the sub-adviser believes leads to strong performance over the long run.
​
•
High Quality Business Models seeks to identify companies that are generating high-quality revenues with sustainable business models and aligned management incentives.
​
•
Sentiment Analysis seeks to identify stocks experiencing improvements in their overall market sentiment.
​
•
Market Themes and Trends seeks to identify companies positively positioned to benefit from themes and trends in the market and macroeconomic environment.
​
As part of the sub-adviser’s investment selection process, the sub-adviser utilizes proprietary models that assess a wide range of indicators. No one indicator, risk or consideration is determinative in the investment selection process. The sub-adviser may make investment decisions that deviate from those generated by the sub-adviser’s proprietary models, at the discretion of the sub-adviser. In addition, the sub-adviser may, in its discretion, make changes to its quantitative techniques, or use other quantitative techniques based on the sub-adviser’s proprietary research.

Pacific Life Fund Advisors LLC (“PLFA”), the investment adviser of the Fund, manages the international equity portion of the Fund while Fidelity Diversifying Solutions LLC (“FDS”) manages the bond portion of the Fund as sub-adviser to that portion of the Fund.
PLFA and FDS normally invest the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at their investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by companies in the Financial sector.
International Equity portion:
The term “international equity” in the Fund’s name refers to derivative investments used to gain exposure to the international equity markets.
For the international equity portion of the Fund, PLFA seeks to gain exposure to the international equity markets using derivatives in a notional amount approximately equal to the Fund’s net assets. Because fewer assets are generally required to gain investment exposure using derivatives than with securities directly, PLFA allocates the remaining assets to the bond portion of the Fund.
These derivatives are total return swap agreements and futures contracts. PLFA seeks to achieve the Fund’s investment goal in this portion of the Fund by gaining exposure to the international equity markets through total return swap agreements and futures contracts on the MSCI Europe, Australasia and Far East (“EAFE”) Index (the “Index”), an equity securities index that represents the large- and mid-capitalization equity markets across various developed countries, including countries in Europe, Australasia and the Far East, excluding the U.S. and Canada.
This portion of the Fund may also invest in futures contracts on other international equity indices to gain exposure to the international equity markets. Using derivatives such as total return swap agreements and futures contracts is a way to obtain investment exposure to the international equity market, as represented by the particular index, and seek the returns of that index without purchasing all of the securities in the index.
PLFA will also seek to achieve additional gains above the Index by making specific investment decisions for the Fund as it sees investment opportunities (“incremental alpha”). To seek incremental alpha, PLFA may use total return swap agreements and/or futures contracts to implement its investment views on sub-asset classes within the overall international equity markets, such as international growth or international value, or single countries or geographic regions. This could involve, for example, buying total return swap agreements on an international growth index to express a positive view on international growth as a sub-asset class. Another example could be hedging out part of the international growth portion of the Index using derivatives, resulting in an overweight to the international value portion, or doing the opposite.
Bond portion: 
The term “bond” in the Fund’s name refers to debt securities and derivatives that provide exposure to debt securities.
The bond portion of the Fund will be managed by FDS to seek to contribute to returns in excess of the Index returns (or “alpha”), to earn income to offset the cost of the Fund’s derivatives investments, and to maintain collateral for the Fund’s derivatives exposure.
This portion of the Fund will be invested primarily in investment grade debt securities, including U.S. debt and U.S. dollar-denominated debt issued by foreign entities in developed markets, and repurchase agreements for those securities. Under normal circumstances, this portion of the Fund is expected to maintain an average credit quality of A- or higher and a weighted average duration that is between 0 and 2.75 years. Duration is often used to measure a bond’s sensitivity to interest rates. The longer this portion of the Fund’s duration, the more sensitive it is to interest rate risk. The shorter this portion of the Fund’s duration, the less sensitive it is to interest rate risk.
When selecting investments for this portion of the Fund, FDS evaluates sectors of the bond market and individual securities within these sectors. FDS selects U.S. dollar-denominated bonds from several sectors including: U.S. and foreign developed market government securities (including agencies); investment grade corporate bonds; mortgage-related securities; asset-backed securities; and cash equivalents.
In addition, FDS may use derivatives, including buying or selling options or futures contracts on a debt security or an index of debt securities, or entering into credit default swaps and interest rate swaps, including options thereon (i.e., swaptions), primarily to manage risks of the debt security investments by increasing or decreasing the exposure to risk factors associated with those investments or as a substitute for investing in the debt securities directly. For example, FDS could use U.S. Treasury futures contracts to manage interest rate risk or credit default swaps to manage credit risk of corporate bonds or gain exposure to debt security investments in a certain sector.
This portion of the Fund may also invest in debt securities issued pursuant to Rule 144A under the Securities Act of 1933 (“Rule 144A securities”).
FDS may purchase or sell investments for this portion of the Fund for a variety of reasons, such as to adjust the Fund’s average maturity, duration, or credit quality or to shift assets into and out of higher yielding or lower yielding securities or different sectors.
This portion of the Fund may lend its portfolio holdings to certain financial institutions.

The Fund normally invests primarily in common stocks of foreign companies, either directly or through depositary receipts,
that, in the sub-adviser’s opinion, appear to offer above average growth potential and trade at a significant discount to the sub-adviser’s assessment of their intrinsic value. Intrinsic value, according to the sub-adviser, is the value of the company measured, to different extents depending on the type of company, on factors such as, but not limited to, the discounted value of the company’s projected future free cash flows, the company’s ability to earn returns on capital in excess of its cost of capital, private market values of similar companies and the costs to replicate the business. The Fund may invest in common stocks of foreign companies of any size located throughout the world that are U.S. dollar or foreign currency-denominated. The sub-adviser considers foreign companies to include those organized, headquartered or that have at least 50% of their assets or derive at least 50% of their revenues or profits from operations outside of the United States. These companies may be located or have substantial operations in emerging markets, provided that the Fund will not invest more than 15% of its net assets at the time of purchase in common stocks or depositary receipts of companies organized, headquartered or with substantial operations in emerging markets. The Fund may also purchase common stocks of U.S. companies. Any income realized will be incidental to the Fund’s investment goal. Common stocks and depositary receipts are considered equity securities.
The selection of common stocks is made through a process whereby companies are identified and selected as investments by examining quantitative and fundamental aspects of the company. This is a bottom up, fundamental method of analysis. The sub-adviser may decide to sell investments given a variety of circumstances, such as when an investment no longer appears to the sub-adviser to offer the potential for long-term growth of capital, when an investment opportunity arises that the sub-adviser believes is more compelling or to realize gains or limit losses.
The sub-adviser normally invests the Fund’s assets across different groups of industries/sectors, but may invest a significant percentage of the Fund’s assets in issuers in a single sector at its investment discretion in seeking the investment goal of the Fund. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Consumer Non-Cyclical sector.

Strategy Narrative [Text Block]
This Fund is a “fund of funds” that seeks to achieve its investment goal by investing in eligible mutual funds that have an ESG (“environmental, social and governance”) focus or that meet Pacific Life Fund Advisors LLC’s (“PLFA’s”) ESG investment criteria in this section. The underlying funds invest in U.S. and foreign equity and debt instruments and are referred to herein as the “ESG Underlying Funds” because they are eligible underlying funds of the Fund.
Under normal market conditions, the Fund’s exposures to the two broad asset classes of debt and equity are expected to be within the following ranges:
​
Broad Asset Class Allocations
 ​
​
Debt
​ ​
Equity
​
​
30 – 50%​
​ ​
50 – 70%
 ​
PLFA, the investment adviser to the Fund, manages and oversees the Fund through the following multi-step process:
(1) Asset Allocation/Portfolio Construction — PLFA manages the Fund using an approximate 10-year investment horizon. An asset class model (the “Model”) for the Fund is developed that seeks to meet the Fund’s investment goal over this period using both broad asset classes and narrower asset classes. The broad equity asset class includes narrower asset classes such as domestic, developed and emerging market international equities. The broad debt asset class includes narrower asset classes such as investment grade bonds and international debt of developed markets of varying durations.
PLFA then determines the amount of the Fund’s assets to invest in each ESG Underlying Fund in order to obtain the asset class exposures designated by the Model for the Fund.
​
PLFA may adjust the broad asset class allocations to any point within the above ranges, and/or adjust the narrower asset class allocations or the allocations to the ESG Underlying Funds at any time as it deems necessary based on PLFA’s views of market conditions, its outlook for various asset classes or other factors (“dynamic positioning”).
For example, PLFA may engage in dynamic positioning for the Fund by adjusting the Model to reflect a shorter term view of the markets or a particular asset class, to seek to capture upside opportunities or mitigate risk from market events, or for cash management purposes. PLFA would then make the appropriate adjustments to its ESG Underlying Fund allocations to reflect the updated asset class allocations in the Model. This dynamic positioning would be implemented consistent with the Fund’s risk/​return profile and investment goal.
(2) ESG Underlying Fund Oversight — PLFA monitors and evaluates the ESG Underlying Funds on an ongoing basis, including an analysis of the investment risks of the ESG Underlying Funds and their impact on the Fund’s risk/return objectives, to seek to ensure that each current ESG Underlying Fund continues to be appropriate for the Fund’s allocations. PLFA will also monitor the available ESG Underlying Funds and consider substitution of ESG Underlying Funds or the addition of new underlying funds should PLFA determine appropriate for the Fund’s investments.
Investments of the ESG Underlying Funds that invest primarily in equity instruments include large- and mid-capitalization companies; and domestic and foreign stocks (which may be U.S. dollar or foreign currency-denominated), including emerging markets stocks.
Investments of the ESG Underlying Funds that invest primarily in debt instruments include: “green” bonds (securities of companies that develop or provide products or services that seek to provide environmental solutions); investment grade debt securities, including U.S. Government securities and corporate bonds; non-investment grade or “high yield/high risk” debt securities; foreign debt securities of developed markets (which may be U.S. dollar or foreign currency-denominated); and debt instruments of varying duration (short, intermediate and long-term).
Certain ESG Underlying Funds may lend their portfolio securities to generate additional income.
The Fund is expected to be as fully invested as practical, although it may maintain liquidity reserves to meet redemption requests.
PLFA monitors and evaluates various ESG attributes of the ESG Underlying Funds. To be selected for investment, an ESG Underlying Fund must satisfy the following ESG criteria:
i)
An ESG Underlying Fund must meet a minimum ESG rating set by PLFA that is applied to ratings provided by established third party ESG ratings providers. These providers base their ratings on the asset-weighted average of ESG risks of the ESG Underlying Funds’ holdings or an assessment of the resilience of an ESG Underlying Fund’s aggregate holdings to long term ESG risks. These ESG risks may be based on information or analysis that differs from the information or
​
analysis an ESG Underlying Fund uses in its investment process. If the ESG risks for an ESG Underlying Fund’s holdings are high, meaning that the ESG Underlying Fund invests in companies that are not managing their ESG risks well, then that ESG Underlying Fund is less likely to receive a high rating from a third party ESG ratings provider; and
ii)
the ESG Underlying Fund’s principal investment strategies, as disclosed in its prospectus, must refer to ESG criteria in describing the ESG Underlying Fund’s process for selecting investments. The ESG criteria may be determined by an independent third-party data provider or by the investment adviser of the ESG Underlying Fund utilizing an internal framework for considering ESG factors. ESG criteria used by one ESG Underlying Fund in its investment process may differ from or be inconsistent with ESG criteria used by other ESG Underlying Funds in their investment processes.
​
ESG Underlying Funds may include both actively managed funds and passively managed (index) funds. If an ESG Underlying Fund is passively managed, and therefore its investment process seeks to provide investment results that correspond to the returns of its benchmark index, then the fund’s benchmark index must include an ESG investment component. PLFA seeks to gain exposure to a broad range of ESG metrics with its allocations to the ESG Underlying Funds.
PLFA will decide whether to adjust an allocation to an ESG Underlying Fund based upon whether such fund continues to meet the requirements described above. If an ESG Underlying Fund falls below the minimum ESG rating set by PLFA from one or more established third party ESG ratings providers, PLFA would re-evaluate the ESG Underlying Fund and determine whether and when to replace the ESG Underlying Fund. PLFA is under no specific time constraint for implementing such a change.
The Fund may invest a significant portion of its assets in any single ESG Underlying Fund, subject to applicable regulatory limits. PLFA has sole discretion in selecting the ESG Underlying Funds for investment and may adjust the Fund’s allocations to the ESG Underlying Funds and add or remove ESG Underlying Funds as it deems appropriate to meet the Fund’s investment goal.
The current ESG Underlying Funds are managed by:
•
BlackRock Advisors, LLC;
​
•
Calvert Research and Management;
​
•
Dimensional Fund Advisors LP; and
​
•
Fidelity Management & Research Company LLC (sub-advised by Geode Capital Management, LLC).
​
Each ESG Underlying Fund factors ESG criteria into its investment process.
BlackRock:
The ESG Underlying Fund managed by BlackRock Advisors, LLC (“BlackRock”) (the “BlackRock Fund”) seeks to provide long-term capital appreciation while seeking to maintain certain ESG characteristics, climate risk exposure and climate opportunities relative to its benchmark index. Under normal
circumstances, the BlackRock Fund seeks to invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities issued by, or tied economically to, companies in emerging markets and derivatives that have similar economic characteristics to such securities. Specifically, the BlackRock Fund generally seeks to invest in a portfolio of equity securities that, in BlackRock’s view, (i) has an aggregate ESG assessment that is better than the aggregate ESG assessment of its benchmark index, (ii) has an aggregate carbon emissions assessment that is lower than that of its benchmark index, and (iii) in the aggregate, identifies issuers that BlackRock believes are better positioned to capture climate opportunities relative to the issuers in its benchmark index. The BlackRock Fund may invest in other sectors that are not included in such assessments. BlackRock seeks to utilize exclusionary screens in determining the investment universe and to incorporate investment insights related to ESG characteristics in the portfolio construction process. To determine the BlackRock Fund’s investable universe, BlackRock will first seek to screen out certain issuers based on ESG criteria determined by BlackRock. Such screening criteria principally includes: (i) issuers that derive more than zero percent of revenue from the production of controversial weapons; (ii) issuers that derive more than zero percent of revenue from the production of civilian firearms; (iii) issuers that derive more than zero percent of revenue from the production of tobacco-related products; (iv) issuers that derive certain revenue from thermal coal generation, unless such issuers either (a) have made certain commitments to reduce climate impact or (b) derive revenue from alternative energy sources; (v) issuers that derive more than five percent of revenue from thermal coal mining; and (vi) issuers that derive more than five percent of revenue from oil sands extraction. Notwithstanding the foregoing, the BlackRock Fund may invest in green bonds of issuers that exceed the thresholds stated in (iv), (v) and (vi) above. The BlackRock Fund relies on one or more third-party ratings agencies to identify issuers for purposes of the above screening criteria. Third-party rating agencies may base the above screening criteria on an estimate when revenue for a covered business activity is not disclosed by the issuer or publicly available. The BlackRock Fund’s screening criteria is measured at the time of investment and is dependent upon information and data that may be incomplete, inaccurate, unavailable or estimated. Where the BlackRock Fund’s criteria looks solely to third-party ratings or data, issuers are only screened to the extent such ratings or data have been assigned or made available by the third parties. This screening criteria is subject to change over time at BlackRock’s discretion. In addition, the BlackRock Fund may gain indirect exposure (through, including but not limited to, derivatives and investments in other investment companies) to issuers with exposures that are inconsistent with the ESG-related criteria used by BlackRock. The BlackRock Fund then seeks to pursue its investment objective by investing in equity securities in a disciplined manner, by using proprietary return forecast models that incorporate quantitative analysis. These forecast models are designed to identify aspects of mispricing across stocks which the BlackRock Fund can seek to capture by over- and under-weighting particular equities while seeking to control incremental risk. BlackRock then constructs and rebalances the portfolio’s weightings by integrating its investment insights with the model-based optimization process. Certain of the
investment insights relate to ESG characteristics in BlackRock defined categories, including, but not limited to, (i) superior growth characteristics of issuers, (ii) risk mitigation characteristics of issuers, (iii) themes related to social matters and (iv) economic transition, which includes, but is not limited to, environmental considerations. Examples of such ESG characteristics include management quality, governance, controversies at issuers, public health analytics and an issuer’s innovation-oriented research and development. The ESG characteristics utilized in the portfolio construction process may change over time and one or more characteristics may not be relevant to all issuers that are eligible for investment. BlackRock’s ESG research does not attempt to capture all possible ESG characteristics, rather those that in BlackRock’s opinion, can be measured and have an associated investment thesis. Fund management may consider both positive and negative ESG characteristics of an issuer when developing such investment theses. BlackRock determines which ESG characteristics to include in the model and what changes are made in the model over time. ESG-related characteristics are not the sole considerations in the portfolio construction process and BlackRock’s evaluation of ESG characteristics may change over time.
Calvert:
Certain ESG Underlying Funds are managed by Calvert Research and Management (“Calvert”) (the “Calvert Funds”). In selecting investments for the Calvert Funds, Calvert is guided by The Calvert Principles for Responsible Investment which provide a framework for considering environmental, social and governance factors. The Calvert Principles for Responsible Investment seek to identify companies and other issuers that operate in a manner that is consistent with or promote: environmental sustainability and resource efficiency; equitable societies and respect for human rights; and accountable governance and transparency. One of the Calvert Funds, the Calvert Green Bond Fund, invests at least 80% of its assets in “green” bonds, which are bonds of companies that develop or provide products or services that seek to provide environmental solutions and/or support efforts to reduce their own environmental footprint; bonds that support environmental projects; structured securities that are collateralized by assets supporting environmental themes; and securities that, in the opinion of Calvert Research and Management, have no more than a negligible direct environmental impact, which may include securities issued by the U.S. government or its agencies, and U.S. government-sponsored entities. Certain Calvert Funds also may invest in trust preferred securities, taxable municipal obligations and loans.
DFA:
Certain ESG Underlying Funds are managed by Dimensional Fund Advisors LP (“DFA”), namely the DFA Social Fixed Income Portfolio and the DFA U.S. Sustainability Core 1 Portfolio.
The DFA Social Fixed Income Portfolio seeks to maximize total returns through exposure to a broad portfolio of investment grade debt securities of U.S. and non-U.S. corporate and government issuers while excluding securities of corporate and certain non-sovereign government issuers based upon the
DFA Social Fixed Income Portfolio’s social issue screens. DFA expects that the DFA Social Fixed Income Portfolio will primarily invest in the obligations of issuers that are in developed countries.
The DFA Social Fixed Income Portfolio seeks to purchase securities that are consistent with the DFA Social Fixed Income Portfolio’s social issue screens, which are monitored by, or based upon information from, an independent third party. The DFA Social Fixed Income Portfolio seeks to exclude from its investment portfolio securities of those companies that are identified by the DFA Social Fixed Income Portfolio’s social issue screens, as further discussed below. The DFA Social Fixed Income Portfolio’s social issue screens are designed to identify companies that: (1) earn at least 10% of their total annual revenue through the production and/or sale of conventional or nuclear weapons, their weapon systems, or key intended components of these products, or the provision of weapon systems support and service related to nuclear weapons, such as the repair and maintenance of nuclear weapons; (2) have demonstrated complicity in genocide in Sudan, for example, by having ties to the Sudanese military or government, selling or distributing military equipment to a party based in Sudan or operating within Sudan borders, or generating 10% or more of its total assets or revenues in Sudan from the oil, mineral or power sectors; (3) earn at least 10% of their total annual revenue through the production and/or sale of tobacco (this criteria does not cover products designed as an aid to quit smoking), alcoholic beverages as an intoxicating agent (this criteria does not cover packaging such as bottles, cans, corks or caps), or cannabis products; (4) earn at least 10% of their total annual revenue from the ownership or operation of gambling facilities, licensing their brand name to gambling products, or providing support or services to the gambling industry; (5) directly participate in abortions, or develop or manufacture abortive agents or contraceptives; (6) earn at least 10% of their total annual revenue from the retail, distribution or production of pornographic products (this criteria does not cover companies that offer content sharing platforms that are not pornography focused but allow third-party users to upload pornographic content; (7) are involved in the production of landmines, cluster munitions, or key intended components of such weapons; (8) produce firearms (i.e., using an explosive charge as a propellant) intended for civilian use; (9) have had involvement in severe child labor controversies (factors that may be considered for determining severity include, but are not limited to, a history of involvement in child labor-related legal cases, widespread or egregious instances of child labor, resistance to improved practices, and criticism by non-governmental organizations and/or other third-party observers); (10) conduct stem cell research using cells derived from human embryos or fetal tissue, or use fetal cell lines in the development of vaccines or other biopharmaceuticals; (11) operate or manage, or provide staffing services to, for-profit correctional and/or detention facilities (this criteria does not cover provision of maintenance or non-management services, including staffing for such services); (12) have material involvement in severe environmental, social or governance controversies that indicate operations inconsistent with responsible business conduct standards, such as those defined by the United Nations Global Compact Principles and the Organization for Economic Co-operation and Development Guidelines for Multinational
Enterprises; (13) have relatively high carbon intensity or potential emissions from reserves or scaled potential emissions from reserves; and/or (14) have thermal or metallurgical coal reserves.
In addition to excluding securities of corporate issuers based upon the DFA Social Fixed Income Portfolio’s social issue screens, the DFA Social Fixed Income Portfolio also will generally exclude securities of supranational organizations and certain non-sovereign governmental agencies (both U.S. and non-U.S. that may be less sustainable as compared to other similar issuers, based upon considerations 13 and 14. The DFA Social Fixed Income Portfolio’s investments in securities of U.S. and non-U.S. sovereign issuers are not subject to the other screens identified above. DFA, however, considers securities issued by the U.S. Treasury and certain U.S. agencies and instrumentalities that are not subject to the DFA Social Fixed Income Portfolio’s social issue screens identified above to be consistent with the DFA Social Fixed Income Portfolio’s strategy of investing in social investments.
The DFA U.S. Sustainability Core 1 Portfolio is designed to purchase a broad and diverse group of securities of U.S. companies. The DFA U.S. Sustainability Core 1 Portfolio invests in companies of all sizes and seeks to moderately increase the DFA U.S. Sustainability Core 1 Portfolio’s exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the U.S. Universe, while adjusting the composition based on sustainability considerations.
DFA intends to take into account certain sustainability considerations when making investment decisions for the DFA U.S. Sustainability Core 1 Portfolio. Relative to a fund without these considerations that otherwise has the same investment objective, strategies, and policies as the DFA U.S. Sustainability Core 1 Portfolio, the DFA U.S. Sustainability Core 1 Portfolio will generally have excluded, and have less overall weight in, securities of companies that, according to the DFA U.S. Sustainability Core 1 Portfolio’s sustainability considerations, may be less sustainable as compared either to other companies in the DFA U.S. Sustainability Core 1 Portfolio’s investment universe. Similarly, relative to such a fund, the DFA U.S. Sustainability Core 1 Portfolio will generally have more overall weight in securities of companies that, according to the DFA U.S. Sustainability Core 1 Portfolio’s sustainability considerations, may be more sustainable as compared to other companies in the DFA U.S. Sustainability Core 1 Portfolio’s investment universe. In particular, DFA ranks companies (i) relative to the broader equity market based on potential emissions from reserves and scaled potential emissions from reserves and the securities of the worst-ranking companies are generally underweighted or excluded, (ii) relative to the applicable universe of securities based on carbon intensity and the securities of the worst-ranking companies are generally underweighted or excluded and (iii) relative to their sector peers based primarily on carbon intensity, but also considering several other factors, including controversies related to land use and biodiversity, toxic spills and releases, operational waste, and water management, and the securities of the worst-ranking companies are generally underweighted or excluded and the securities of the remaining companies are
generally overweighted or neutral-weighted. In addition, DFA seeks to exclude securities of companies based on sustainability considerations relating to coal, factory farming, palm oil, cluster munitions and landmines, tobacco, child labor, civilian firearms, private prisons, and material involvement in severe environmental, social, or governance controversies that indicate operations inconsistent with responsible business conduct standards (such as those defined by the United Nations Global Compact Principles and the Organization for Economic Co-operation and Development Guidelines for Multinational Enterprises). DFA engages third party service providers to provide research information relating to the DFA U.S. Sustainability Core 1 Portfolio’s sustainability considerations with respect to securities in the DFA U.S. Sustainability Core 1 Portfolio, where information is available from such providers. DFA also may use, or supplement third party service providers’ data with, proprietary research relating to certain sustainability considerations where information is not available or has not been obtained from third party service providers engaged by DFA.
Fidelity/Geode:
The ESG Underlying Funds managed by Fidelity Management & Research Company LLC (“Fidelity”), as sub-advised by Geode Capital Management, LLC (“Geode”) are index funds that seek to provide investment results that correspond to the total return of their respective indexes that represent companies with high ESG performance relative to their sector peers, as rated by independent third parties. These index funds may use index sampling techniques (also known as statistical sampling) based on such factors as capitalization, industry exposures, dividend yield, price-to-earnings (P/E) ratio, price-to-book (P/B) ratio, and earnings growth to attempt to replicate the returns of their respective indexes using a smaller number of securities.
BlackRock, Calvert, DFA, Fidelity, and Geode are not affiliated with the Trust, the Fund or the Fund’s investment adviser. The Fund may invest in any or all of the ESG Underlying Funds managed by these investment advisers and will not necessarily be invested in every ESG Underlying Fund at any particular time. Accordingly, although described in this section, not all ESG Underlying Funds are principal investments of the Fund at any given time.

This Fund is a “fund of funds” that seeks to achieve its investment goal by investing in eligible mutual funds that have an ESG (“environmental, social and governance”) focus or that meet Pacific Life Fund Advisors LLC’s (“PLFA’s”) ESG investment criteria in this section. The underlying funds invest in U.S. and foreign equity and debt instruments and are referred to herein as the “ESG Underlying Funds” because they are eligible underlying funds of the Fund.
Under normal market conditions, the Fund’s exposures to the two broad asset classes of debt and equity are expected to be within the following ranges:
​
Broad Asset Class Allocations
 ​
​
Debt
​ ​
Equity
​
​
15 – 30%​
​ ​
70 – 85%
 ​
PLFA, the investment adviser to the Fund, manages and oversees the Fund through the following multi-step process:
(1) Asset Allocation/Portfolio Construction — PLFA manages the Fund using an approximate 10-year investment horizon. An asset class model (the “Model”) for the Fund is developed that seeks to meet the Fund’s investment goal over this period using both broad asset classes and narrower asset classes. The broad equity asset class includes narrower asset classes such as domestic, developed and emerging market international equities. The broad debt asset class includes narrower asset classes such as investment grade bonds and international debt of developed markets of varying durations.
PLFA then determines the amount of the Fund’s assets to invest in each ESG Underlying Fund in order to obtain the asset class exposures designated by the Model for the Fund.
PLFA may adjust the broad asset class allocations to any point within the above ranges, and/or adjust the narrower asset class allocations or the allocations to the ESG Underlying Funds at any time as it deems necessary based on PLFA’s views of market conditions, its outlook for various asset classes or other factors (“dynamic positioning”).
For example, PLFA may engage in dynamic positioning for the Fund by adjusting the Model to reflect a shorter term view of the markets or a particular asset class, to seek to capture upside opportunities or mitigate risk from market events, or for cash management purposes. PLFA would then make the appropriate adjustments to its ESG Underlying Fund allocations to reflect the updated asset class allocations in the Model. This dynamic positioning would be implemented consistent with the Fund’s risk/​return profile and investment goal.
(2) ESG Underlying Fund Oversight — PLFA monitors and evaluates the ESG Underlying Funds on an ongoing basis, including an analysis of the investment risks of the ESG Underlying Funds and their impact on the Fund’s risk/return objectives, to seek to ensure that each current ESG Underlying Fund continues to be appropriate for the Fund’s allocations. PLFA will also monitor the available ESG Underlying Funds and consider substitution of ESG Underlying Funds or the addition of new underlying funds should PLFA determine appropriate for the Fund’s investments.
Investments of the ESG Underlying Funds that invest primarily in equity instruments include large- and mid-capitalization companies; and domestic and foreign stocks (which may be U.S. dollar or foreign currency-denominated), including emerging markets stocks.
Investments of the ESG Underlying Funds that invest primarily in debt instruments include: “green” bonds (securities of companies that develop or provide products or services that seek to provide environmental solutions); investment grade debt securities, including U.S. Government securities and corporate bonds; non-investment grade or “high yield/high risk” debt securities; foreign debt securities of developed markets (which may be U.S. dollar or foreign currency-denominated); and debt instruments of varying duration (short, intermediate and long-term).
Certain ESG Underlying Funds may lend their portfolio securities to generate additional income.
The Fund is expected to be as fully invested as practical, although it may maintain liquidity reserves to meet redemption requests.
PLFA monitors and evaluates various ESG attributes of the ESG Underlying Funds. To be selected for investment, an ESG Underlying Fund must satisfy the following ESG criteria:
i)
An ESG Underlying Fund must meet a minimum ESG rating set by PLFA that is applied to ratings provided by established third party ESG ratings providers. These providers base their ratings on the asset-weighted average of ESG risks of the ESG Underlying Funds’ holdings or an assessment of the resilience of an ESG Underlying Fund’s aggregate holdings to long term ESG risks. These ESG risks may be based on information or analysis that differs from the information or
​
analysis an ESG Underlying Fund uses in its investment process. If the ESG risks for an ESG Underlying Fund’s holdings are high, meaning that the ESG Underlying Fund invests in companies that are not managing their ESG risks well, then that ESG Underlying Fund is less likely to receive a high rating from a third party ESG ratings provider; and
ii)
the ESG Underlying Fund’s principal investment strategies, as disclosed in its prospectus, must refer to ESG criteria in describing the ESG Underlying Fund’s process for selecting investments. The ESG criteria may be determined by an independent third-party data provider or by the investment adviser of the ESG Underlying Fund utilizing an internal framework for considering ESG factors. ESG criteria used by one ESG Underlying Fund in its investment process may differ from or be inconsistent with ESG criteria used by other ESG Underlying Funds in their investment processes.
​
ESG Underlying Funds may include both actively managed funds and passively managed (index) funds. If an ESG Underlying Fund is passively managed, and therefore its investment process seeks to provide investment results that correspond to the returns of its benchmark index, then the fund’s benchmark index must include an ESG investment component. PLFA seeks to gain exposure to a broad range of ESG metrics with its allocations to the ESG Underlying Funds.
PLFA will decide whether to adjust an allocation to an ESG Underlying Fund based upon whether such fund continues to meet the requirements described above. If an ESG Underlying Fund falls below the minimum ESG rating set by PLFA from one or more established third party ESG ratings providers, PLFA would re-evaluate the ESG Underlying Fund and determine whether and when to replace the ESG Underlying Fund. PLFA is under no specific time constraint for implementing such a change.
The Fund may invest a significant portion of its assets in any single ESG Underlying Fund, subject to applicable regulatory limits. PLFA has sole discretion in selecting the ESG Underlying Funds for investment and may adjust the Fund’s allocations to the ESG Underlying Funds and add or remove ESG Underlying Funds as it deems appropriate to meet the Fund’s investment goal.
The current ESG Underlying Funds are managed by:
•
BlackRock Advisors, LLC;
​
•
Calvert Research and Management;
​
•
Dimensional Fund Advisors LP; and
​
•
Fidelity Management & Research Company LLC (sub-advised by Geode Capital Management, LLC).
​
Each ESG Underlying Fund factors ESG criteria into its investment process.
BlackRock:
The ESG Underlying Fund managed by BlackRock Advisors, LLC (“BlackRock”) (the “BlackRock Fund”) seeks to provide long-term capital appreciation while seeking to maintain certain ESG characteristics, climate risk exposure and climate opportunities relative to its benchmark index. Under normal
circumstances, the BlackRock Fund seeks to invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities issued by, or tied economically to, companies in emerging markets and derivatives that have similar economic characteristics to such securities. Specifically, the BlackRock Fund generally seeks to invest in a portfolio of equity securities that, in BlackRock’s view, (i) has an aggregate ESG assessment that is better than the aggregate ESG assessment of its benchmark index, (ii) has an aggregate carbon emissions assessment that is lower than that of its benchmark index, and (iii) in the aggregate, identifies issuers that BlackRock believes are better positioned to capture climate opportunities relative to the issuers in its benchmark index. The BlackRock Fund may invest in other sectors that are not included in such assessments. BlackRock seeks to utilize exclusionary screens in determining the investment universe and to incorporate investment insights related to ESG characteristics in the portfolio construction process. To determine the BlackRock Fund’s investable universe, BlackRock will first seek to screen out certain issuers based on ESG criteria determined by BlackRock. Such screening criteria principally includes: (i) issuers that derive more than zero percent of revenue from the production of controversial weapons; (ii) issuers that derive more than zero percent of revenue from the production of civilian firearms; (iii) issuers that derive more than zero percent of revenue from the production of tobacco-related products; (iv) issuers that derive certain revenue from thermal coal generation, unless such issuers either (a) have made certain commitments to reduce climate impact or (b) derive revenue from alternative energy sources; (v) issuers that derive more than five percent of revenue from thermal coal mining; and (vi) issuers that derive more than five percent of revenue from oil sands extraction. Notwithstanding the foregoing, the BlackRock Fund may invest in green bonds of issuers that exceed the thresholds stated in (iv), (v) and (vi) above. The BlackRock Fund relies on one or more third-party ratings agencies to identify issuers for purposes of the above screening criteria. Third-party rating agencies may base the above screening criteria on an estimate when revenue for a covered business activity is not disclosed by the issuer or publicly available. The BlackRock Fund’s screening criteria is measured at the time of investment and is dependent upon information and data that may be incomplete, inaccurate, unavailable or estimated. Where the BlackRock Fund’s criteria looks solely to third-party ratings or data, issuers are only screened to the extent such ratings or data have been assigned or made available by the third parties. This screening criteria is subject to change over time at BlackRock’s discretion. In addition, the BlackRock Fund may gain indirect exposure (through, including but not limited to, derivatives and investments in other investment companies) to issuers with exposures that are inconsistent with the ESG-related criteria used by BlackRock. The BlackRock Fund then seeks to pursue its investment objective by investing in equity securities in a disciplined manner, by using proprietary return forecast models that incorporate quantitative analysis. These forecast models are designed to identify aspects of mispricing across stocks which the BlackRock Fund can seek to capture by over- and under-weighting particular equities while seeking to control incremental risk. BlackRock then constructs and rebalances the portfolio’s weightings by integrating its investment insights with the model-based optimization process. Certain of the
investment insights relate to ESG characteristics in BlackRock defined categories, including, but not limited to, (i) superior growth characteristics of issuers, (ii) risk mitigation characteristics of issuers, (iii) themes related to social matters and (iv) economic transition, which includes, but is not limited to, environmental considerations. Examples of such ESG characteristics include management quality, governance, controversies at issuers, public health analytics and an issuer’s innovation-oriented research and development. The ESG characteristics utilized in the portfolio construction process may change over time and one or more characteristics may not be relevant to all issuers that are eligible for investment. BlackRock’s ESG research does not attempt to capture all possible ESG characteristics, rather those that in BlackRock’s opinion, can be measured and have an associated investment thesis. Fund management may consider both positive and negative ESG characteristics of an issuer when developing such investment theses. BlackRock determines which ESG characteristics to include in the model and what changes are made in the model over time. ESG-related characteristics are not the sole considerations in the portfolio construction process and BlackRock’s evaluation of ESG characteristics may change over time.
Calvert:
Certain ESG Underlying Funds are managed by Calvert Research and Management (“Calvert”) (the “Calvert Funds”). In selecting investments for the Calvert Funds, Calvert is guided by The Calvert Principles for Responsible Investment which provide a framework for considering environmental, social and governance factors. The Calvert Principles for Responsible Investment seek to identify companies and other issuers that operate in a manner that is consistent with or promote: environmental sustainability and resource efficiency; equitable societies and respect for human rights; and accountable governance and transparency. One of the Calvert Funds, the Calvert Green Bond Fund, invests at least 80% of its assets in “green” bonds, which are bonds of companies that develop or provide products or services that seek to provide environmental solutions and/or support efforts to reduce their own environmental footprint; bonds that support environmental projects; structured securities that are collateralized by assets supporting environmental themes; and securities that, in the opinion of Calvert Research and Management, have no more than a negligible direct environmental impact, which may include securities issued by the U.S. government or its agencies, and U.S. government-sponsored entities. Certain Calvert Funds also may invest in trust preferred securities, taxable municipal obligations and loans.
DFA:
Certain ESG Underlying Funds are managed by Dimensional Fund Advisors LP (“DFA”), namely the DFA Social Fixed Income Portfolio and the DFA U.S. Sustainability Core 1 Portfolio.
The DFA Social Fixed Income Portfolio seeks to maximize total returns through exposure to a broad portfolio of investment grade debt securities of U.S. and non-U.S. corporate and government issuers while excluding securities of corporate and certain non-sovereign government issuers based upon the
DFA Social Fixed Income Portfolio’s social issue screens. DFA expects that the DFA Social Fixed Income Portfolio will primarily invest in the obligations of issuers that are in developed countries.
The DFA Social Fixed Income Portfolio seeks to purchase securities that are consistent with the DFA Social Fixed Income Portfolio’s social issue screens, which are monitored by, or based upon information from, an independent third party. The DFA Social Fixed Income Portfolio seeks to exclude from its investment portfolio securities of those companies that are identified by the DFA Social Fixed Income Portfolio’s social issue screens, as further discussed below. The DFA Social Fixed Income Portfolio’s social issue screens are designed to identify companies that: (1) earn at least 10% of their total annual revenue through the production and/or sale of conventional or nuclear weapons, their weapon systems, or key intended components of these products, or the provision of weapon systems support and service related to nuclear weapons, such as the repair and maintenance of nuclear weapons; (2) have demonstrated complicity in genocide in Sudan, for example, by having ties to the Sudanese military or government, selling or distributing military equipment to a party based in Sudan or operating within Sudan borders, or generating 10% or more of its total assets or revenues in Sudan from the oil, mineral or power sectors; (3) earn at least 10% of their total annual revenue through the production and/or sale of tobacco (this criteria does not cover products designed as an aid to quit smoking), alcoholic beverages as an intoxicating agent (this criteria does not cover packaging such as bottles, cans, corks or caps), or cannabis products; (4) earn at least 10% of their total annual revenue from the ownership or operation of gambling facilities, licensing their brand name to gambling products, or providing support or services to the gambling industry; (5) directly participate in abortions, or develop or manufacture abortive agents or contraceptives; (6) earn at least 10% of their total annual revenue from the retail, distribution or production of pornographic products (this criteria does not cover companies that offer content sharing platforms that are not pornography focused but allow third-party users to upload pornographic content; (7) are involved in the production of landmines, cluster munitions, or key intended components of such weapons; (8) produce firearms (i.e., using an explosive charge as a propellant) intended for civilian use; (9) have had involvement in severe child labor controversies (factors that may be considered for determining severity include, but are not limited to, a history of involvement in child labor-related legal cases, widespread or egregious instances of child labor, resistance to improved practices, and criticism by non-governmental organizations and/or other third-party observers); (10) conduct stem cell research using cells derived from human embryos or fetal tissue, or use fetal cell lines in the development of vaccines or other biopharmaceuticals; (11) operate or manage, or provide staffing services to, for-profit correctional and/or detention facilities (this criteria does not cover provision of maintenance or non-management services, including staffing for such services); (12) have material involvement in severe environmental, social or governance controversies that indicate operations inconsistent with responsible business conduct standards, such as those defined by the United Nations Global Compact Principles and the Organization for Economic Co-operation and Development Guidelines for Multinational
Enterprises; (13) have relatively high carbon intensity or potential emissions from reserves or scaled potential emissions from reserves; and/or (14) have thermal or metallurgical coal reserves.
In addition to excluding securities of corporate issuers based upon the DFA Social Fixed Income Portfolio’s social issue screens, the DFA Social Fixed Income Portfolio also will generally exclude securities of supranational organizations and certain non-sovereign governmental agencies (both U.S. and non-U.S. that may be less sustainable as compared to other similar issuers, based upon considerations 13 and 14. The DFA Social Fixed Income Portfolio’s investments in securities of U.S. and non-U.S. sovereign issuers are not subject to the other screens identified above. DFA, however, considers securities issued by the U.S. Treasury and certain U.S. agencies and instrumentalities that are not subject to the DFA Social Fixed Income Portfolio’s social issue screens identified above to be consistent with the DFA Social Fixed Income Portfolio’s strategy of investing in social investments.
The DFA U.S. Sustainability Core 1 Portfolio is designed to purchase a broad and diverse group of securities of U.S. companies. The DFA U.S. Sustainability Core 1 Portfolio invests in companies of all sizes and seeks to moderately increase the DFA U.S. Sustainability Core 1 Portfolio’s exposure to smaller capitalization, lower relative price, and higher profitability companies as compared to their representation in the U.S. Universe, while adjusting the composition based on sustainability considerations.
DFA intends to take into account certain sustainability considerations when making investment decisions for the DFA U.S. Sustainability Core 1 Portfolio. Relative to a fund without these considerations that otherwise has the same investment objective, strategies, and policies as the DFA U.S. Sustainability Core 1 Portfolio, the DFA U.S. Sustainability Core 1 Portfolio will generally have excluded, and have less overall weight in, securities of companies that, according to the DFA U.S. Sustainability Core 1 Portfolio’s sustainability considerations, may be less sustainable as compared either to other companies in the DFA U.S. Sustainability Core 1 Portfolio’s investment universe. Similarly, relative to such a fund, the DFA U.S. Sustainability Core 1 Portfolio will generally have more overall weight in securities of companies that, according to the DFA U.S. Sustainability Core 1 Portfolio’s sustainability considerations, may be more sustainable as compared to other companies in the DFA U.S. Sustainability Core 1 Portfolio’s investment universe. In particular, DFA ranks companies (i) relative to the broader equity market based on potential emissions from reserves and scaled potential emissions from reserves and the securities of the worst-ranking companies are generally underweighted or excluded, (ii) relative to the applicable universe of securities based on carbon intensity and the securities of the worst-ranking companies are generally underweighted or excluded and (iii) relative to their sector peers based primarily on carbon intensity, but also considering several other factors, including controversies related to land use and biodiversity, toxic spills and releases, operational waste, and water management, and the securities of the worst-ranking companies are generally underweighted or excluded and the securities of the remaining companies are
generally overweighted or neutral-weighted. In addition, DFA seeks to exclude securities of companies based on sustainability considerations relating to coal, factory farming, palm oil, cluster munitions and landmines, tobacco, child labor, civilian firearms, private prisons, and material involvement in severe environmental, social, or governance controversies that indicate operations inconsistent with responsible business conduct standards (such as those defined by the United Nations Global Compact Principles and the Organization for Economic Co-operation and Development Guidelines for Multinational Enterprises). DFA engages third party service providers to provide research information relating to the DFA U.S. Sustainability Core 1 Portfolio’s sustainability considerations with respect to securities in the DFA U.S. Sustainability Core 1 Portfolio, where information is available from such providers. DFA also may use, or supplement third party service providers’ data with, proprietary research relating to certain sustainability considerations where information is not available or has not been obtained from third party service providers engaged by DFA.
Fidelity/Geode:
The ESG Underlying Funds managed by Fidelity Management & Research Company LLC (“Fidelity”), as sub-advised by Geode Capital Management, LLC (“Geode”) are index funds that seek to provide investment results that correspond to the total return of their respective indexes that represent companies with high ESG performance relative to their sector peers, as rated by independent third parties. These index funds may use index sampling techniques (also known as statistical sampling) based on such factors as capitalization, industry exposures, dividend yield, price-to-earnings (P/E) ratio, price-to-book (P/B) ratio, and earnings growth to attempt to replicate the returns of their respective indexes using a smaller number of securities.
BlackRock, Calvert, DFA, Fidelity, and Geode are not affiliated with the Trust, the Fund or the Fund’s investment adviser. The Fund may invest in any or all of the ESG Underlying Funds managed by these investment advisers and will not necessarily be invested in every ESG Underlying Fund at any particular time. Accordingly, although described in this section, not all ESG Underlying Funds are principal investments of the Fund at any given time.

This Fund is a “fund of funds” that seeks to achieve its investment goal by investing in eligible third-party mutual funds, exchange-traded funds (“ETFs”) and/or variable insurance trusts (the “Balanced Allocation Underlying Funds”). Substantially all of the Balanced Allocation Underlying Funds are advised by American Century Investment Management, Inc. (“American Century”), including through its division Avantis Investors (Avantis Investors and American Century are referred to together in this Prospectus as “Avantis”). Avantis is not affiliated with the Trust, the Fund or the Fund’s investment adviser. PLFA may change any or all of the Balanced Allocation Underlying Funds, including to funds offered by another investment adviser, at any time in its investment discretion.
The Balanced Allocation Underlying Funds invest in U.S. and foreign equity and debt instruments. Under normal market conditions, the Fund’s exposures to the two broad asset classes of debt and equity are expected to be within the following ranges:
​
BROAD ASSET CLASS ALLOCATIONS
 ​
​
Debt
​ ​
Equity
​
​
25 – 50%​
​ ​
50 – 75%
 ​
Pacific Life Fund Advisors LLC (“PLFA”), the investment adviser to the Fund, manages and oversees the Fund through the following multi-step process:
(1) Asset Allocation/Portfolio Construction — PLFA manages the Fund using an approximate 10 year investment horizon. An asset class model (the “Model”) for the Fund is developed that seeks to meet the Fund’s investment goal over this period using both broad asset classes and narrower asset classes. The broad equity asset class includes narrower asset classes such as domestic and developed international equities, which may include small-capitalization, mid-capitalization, and large-capitalization equities that may employ growth and value strategies. The broad debt asset class includes narrower asset classes such as investment grade bonds and international debt of developed markets of varying durations.
PLFA then determines the amount of the Fund’s assets to invest in each Balanced Allocation Underlying Fund in order to obtain the asset class exposures designated by the Model for the Fund.
PLFA may adjust the broad asset class allocations to any point within the above ranges, and/or adjust the narrower asset class allocations or the allocations to the Balanced Allocation Underlying Funds at any time as it deems necessary based on PLFA’s views of market conditions, its outlook for various asset classes or other factors (“dynamic positioning”).
For example, PLFA may engage in dynamic positioning for the Fund by adjusting the Model to reflect a shorter term view of the markets or a particular asset class, to seek to capture upside
opportunities or mitigate risk from market events, or for cash management purposes. PLFA would then make the appropriate adjustments to its Balanced Allocation Underlying Fund allocations to reflect the updated asset class allocations in the Model. This dynamic positioning would be implemented consistent with the Fund’s risk/return profile and investment goal.
(2) Balanced Allocation Underlying Fund Oversight — PLFA monitors and evaluates the Balanced Allocation Underlying Funds on an ongoing basis, including an analysis of the investment risks of the Balanced Allocation Underlying Funds and their impact on the Fund’s risk/return objectives, to seek to ensure that each current Balanced Allocation Underlying Fund continues to be appropriate for the Fund’s allocations. PLFA will also monitor the available Balanced Allocation Underlying Funds and consider substitution of Balanced Allocation Underlying Funds or the addition of new underlying funds should PLFA determine appropriate for the Fund’s investments.
Investments of the Balanced Allocation Underlying Funds that invest primarily in equity instruments include: growth and value stocks; large-, mid- and small-capitalization companies; sector-specific stocks; and domestic and foreign stocks (which may be U.S. dollar or foreign currency-denominated).
Investments of the Balanced Allocation Underlying Funds that invest primarily in debt instruments include: investment grade debt securities, including U.S. Government securities and corporate bonds; foreign debt securities of developed markets (which may be U.S. dollar or foreign currency-denominated); and debt instruments of varying duration (short, intermediate and long-term).
Certain Balanced Allocation Underlying Funds may also use derivatives such as: forward commitments; futures contracts and options on securities, indices, currencies, and other investments; and swaps (including credit default swaps). A Balanced Allocation Underlying Fund may use derivatives generally as a substitute for direct investment in a security, to attempt to hedge or reduce risk, or to seek to enhance investment returns.
Balanced Allocation Underlying Funds may include both actively managed funds and passively managed (index) funds.
The Fund, through the Balanced Allocation Underlying Funds, may invest a large percentage of its assets in issuers located in a single country, a small number of countries, or a particular geographic region.
Certain Balanced Allocation Underlying Funds may lend their portfolio securities to generate additional income.
The Fund is expected to be as fully invested as practical, although it may maintain liquidity reserves to meet redemption requests.
The Fund may invest a significant portion of its assets in any single Balanced Allocation Underlying Fund, subject to applicable regulatory limits. PLFA has sole discretion in selecting the Balanced Allocation Underlying Funds for investment and may adjust the Fund’s allocations to the Balanced Allocation Underlying Funds as it deems appropriate to meet the Fund’s investment goal.
The Fund may lend its holdings of ETFs to certain financial institutions.

PLFA then determines the amount of the Fund’s assets to invest in each Pacific Dynamix Underlying Fund in order to obtain the asset class exposures designated by the Model for the Fund.
PLFA may adjust the broad asset class allocations to any point within the above ranges, and/or adjust the narrower asset class allocations or the allocations to the Pacific Dynamix Underlying Funds at any time as it deems necessary based on PLFA’s views of market conditions, its outlook for various asset classes or other factors (“dynamic positioning”).
For example, PLFA may engage in dynamic positioning for the Fund by adjusting the Model to reflect a shorter term view of the markets or a particular asset class, to seek to capture upside opportunities or mitigate risk from market events, or for cash management purposes. PLFA would then make the appropriate adjustments to its Pacific Dynamix Underlying Fund allocations to reflect the updated asset class allocations in the Model. This dynamic positioning would be implemented consistent with the Fund’s risk/return profile and investment goal.
(2) Manager Oversight —  PLFA monitors and evaluates the Pacific Dynamix Underlying Fund Managers to seek to ensure that each Manager’s investment style and approach continue to be appropriate for the respective Pacific Dynamix Underlying Fund.
(3) Investment Risk Management — PLFA monitors and analyzes the investment risks of the Fund, evaluates their impact on the Fund’s risk/return objectives and considers adjustments to the Fund’s allocations as a result.
The Pacific Dynamix Underlying Funds in which the Fund invests are index funds (including index sampling funds), which means that they seek to match the investment returns of specified stock or bond indices. Some of these Pacific Dynamix Underlying Funds, in order to track the composition of their indices, may become non-diversified under the Investment Company Act of 1940 (“1940 Act”).
Investments of the Pacific Dynamix Underlying Funds that invest primarily in debt instruments include: investment grade debt securities, which may include U.S. Government securities, corporate bonds, mortgage-related securities, and other asset-backed securities; foreign debt securities; debt instruments of varying duration; and high yield/high risk bonds.
Investments of the Pacific Dynamix Underlying Funds that invest primarily in equity instruments include: growth and value stocks; mid- and large-capitalization companies; and domestic and foreign stocks (which may be U.S. dollar or foreign currency-denominated).
The Fund may invest a significant portion of its assets in any single Pacific Dynamix Underlying Fund. PLFA has sole discretion in selecting the Pacific Dynamix Underlying Funds for investment and may adjust the Fund’s allocations to the Pacific Dynamix Underlying Funds, and add or remove Pacific Dynamix Underlying Funds, as it deems appropriate to meet the Fund’s investment goal. The Fund will be as fully invested as practical, although it may maintain liquidity reserves to meet redemption requests.
A Pacific Dynamix Underlying Fund may lend its portfolio holdings to certain financial institutions.

The broad equity asset class includes narrower asset classes such as domestic small-capitalization, mid-capitalization and large-capitalization, growth and value strategies, and international and emerging markets. The broad debt asset class includes narrower asset classes such as investment grade bonds, high yield/high risk bonds, bank loans, international and emerging markets.
PLFA then determines the amount of the Fund’s assets to invest in each Portfolio Optimization Underlying Fund in order to obtain the asset class exposures designated by the Model for the Fund.
PLFA may adjust the broad asset class allocations to any point within the above ranges, and/or adjust the narrower asset class allocations or the allocations to the Portfolio Optimization Underlying Funds, at any time as it deems necessary based on PLFA’s views of market conditions, its outlook for various asset classes or other factors that it determines are relevant in seeking to achieve the Fund’s investment goal (“dynamic positioning”).
For example, PLFA may engage in dynamic positioning for the Fund by adjusting the Model to reflect a shorter term view of the markets or a particular asset class, to seek to capture upside opportunities or mitigate risk from market events, or for cash management purposes. PLFA would then make the appropriate adjustments to the Fund’s Portfolio Optimization Underlying Fund allocations to reflect the updated asset class allocations in the Model. This dynamic positioning would be implemented consistent with the Fund’s risk/return profile and investment goal.
(2) Manager Oversight —  PLFA monitors and evaluates the Portfolio Optimization Underlying Fund Managers to seek to ensure that each Manager’s investment style and approach continue to be appropriate for the respective Portfolio Optimization Underlying Fund.
(3) Investment Risk Management — PLFA monitors and analyzes the investment risks of the Fund, evaluates their impact on the Fund’s risk/return objectives and considers adjustments to the Fund’s allocations as a result.
Investments of the Portfolio Optimization Underlying Funds that invest primarily in debt instruments include: investment grade debt securities, including U.S. Government securities, corporate bonds, mortgage-related securities, and other asset-backed securities; foreign debt securities, including emerging market debt; debt instruments of varying duration; convertible securities; high yield/high risk bonds; and inflation-indexed bonds.
Investments of the Portfolio Optimization Underlying Funds that invest primarily in equity instruments include: growth and value stocks; large-, mid- and small-capitalization companies; stocks of companies with a history of paying dividends; sector-specific stocks; and domestic and foreign stocks, including emerging market stocks (which may be U.S. dollar or foreign currency-denominated).
Certain Portfolio Optimization Underlying Funds may also use derivatives such as: forward commitments; futures contracts and options on securities, indices, currencies and other investments; and swaps (including interest rate, cross-currency, total return and credit default swaps). A Portfolio Optimization Underlying Fund may use derivatives generally as a substitute for direct investment in a security, to attempt to hedge or reduce risk or to seek to enhance investment returns.
The Fund is expected to be as fully invested as practical, although it may maintain liquidity reserves to meet redemption requests.
The Fund may invest a significant portion of its assets in any single Portfolio Optimization Underlying Fund. PLFA has sole discretion in selecting the Portfolio Optimization Underlying Funds for investment and may adjust the Fund’s allocations to the Portfolio Optimization Underlying Funds, and add or remove Portfolio Optimization Underlying Funds, as it deems appropriate to meet the Fund’s investment goal.
A Portfolio Optimization Underlying Fund may lend its portfolio holdings to certain financial institutions.

Strategy Narrative [Text Block]
Under normal circumstances, this Fund invests at least 80% of its assets in corporate bonds. These debt securities are those that are included in the Bloomberg US 1-3 Year Corporate Bond Index (“Corporate Bond Index”) or are those securities that the sub-adviser has determined have economic characteristics that are substantially identical to the economic characteristics of the
debt securities that comprise the Corporate Bond Index. The Corporate Bond Index is designed to measure the performance of the short-term U.S. corporate bond market in that it includes publicly issued corporate U.S. debt securities and U.S. dollar-denominated corporate foreign debt securities that have a remaining maturity of greater than or equal to 1 year and less than 3 years, are rated investment grade, and have $300 million or more of outstanding face value. In addition, the securities must be fixed rate or in its fixed rate term (when it is variable rate debt securities) and non-convertible. The sub-adviser seeks to match the total return of the Corporate Bond Index before taking into account Fund costs (fees and expenses).
The sub-adviser does not intend to purchase all of the securities in the Corporate Bond Index, but rather will utilize a “sampling” methodology. Sampling means that the sub-adviser will select securities that represent a sample of securities in the Corporate Bond Index that have a similar investment profile as the entire Corporate Bond Index in terms of key risk factors, performance attributes and other characteristics. The sub-adviser generally expects the Fund to hold less than the total number of securities in the Corporate Bond Index, but reserves the right to hold as many securities as it believes necessary to meet the Fund’s investment goal. The quantity of holdings in the Fund will be based on a number of factors, including the Fund’s asset size. The Fund will not concentrate, except to the same approximate extent as its index may concentrate in the securities of a particular industry or group of industries. As of December 31, 2024, a significant portion of the Fund is represented by securities of companies in the Financial sector. The weightings of the Fund are likely to change over time as the composition of the index changes over time.
The Fund may invest up to 20% of its assets in corporate bonds of U.S. and foreign issuers that are U.S. dollar-denominated and not currently in the Corporate Bond Index that have a remaining maturity of less than 1 year or greater than or equal to 3 years but less than 4 years, as long as the purchase of such corporate bonds does not cause the weighted average maturity of the Fund to be less than 1 year or greater than or equal to 3 years. Within this 20% limit, up to 10% of the Fund’s assets may be invested in corporate bonds that have a remaining maturity of less than 1 year, and up to 10% of the Fund’s assets may be invested in corporate bonds that have a remaining maturity of greater than or equal to 3 years but less than 4 years.

Under normal circumstances, this Fund invests at least 80% of its assets in non-investment grade (high yield/high risk) debt instruments, including instruments with characteristics of non-investment grade debt instruments (such as derivatives). Non-investment grade (high yield/high risk) debt instruments are sometimes called “junk bonds.” These instruments are those
that are included in the Bloomberg US High-Yield 2% Issuer Capped Bond Index (“High Yield Index”) or have economic characteristics similar to securities included in that index. The sub-adviser seeks to match the total return of the High Yield Index, before taking into account Fund costs (fees and expenses). The High Yield Index is an index that is an issuer constrained version of the Bloomberg US Corporate High-Yield Bond Index which covers the U.S. dollar-denominated, non-investment grade, fixed-rate taxable corporate bond market and limits issuer exposures to a maximum of 2% and redistributes the excess market value index-wide on a pro-rata basis. The High Yield Index represents the securities of the U.S. dollar-denominated non-investment grade bond market.
The sub-adviser does not intend to purchase all of the securities in the High Yield Index, but rather will utilize a “sampling” methodology.
