The second sentence of the second paragraph of each PL Portfolio Optimization Fund's Principal investment strategies subsection is replaced with the following:

Within the broad asset classes of debt and equity, the fund diversifies its holdings by investing in Underlying Funds that represent a variety of investment styles and security types, including alternative or non-traditional investment strategies. Alternative or non-traditional investment strategies generally are expected to have low to moderate correlation to traditional equity and fixed income investments and, as a result, may offer diversification benefits.

In the same subsection, the following is added as the fourth paragraph:

The portion of the fund invested in alternative or non-traditional investment strategies may be allocated to Underlying Funds that, in turn, invest in equity or debt securities or other instruments, which may include, among others:

• Forward foreign currency contracts;

• Foreign currency options;

• High yield debt securities;

• Swaps (such as interest rate, cross-currency, total return and credit default swaps);

• Futures on securities, indexes, currencies and other investments; and

• Precious metals-related equity securities.

In the same subsection, the first sentence of the current fourth paragraph is replaced with the following:

The fund may also, at any time invest in Underlying Funds that hold other debt or equity securities or other instruments. 

The following is added to each PL Portfolio Optimization Fund's Principal risks from holdings in Underlying Funds subsection:

• Correlation Risk: While the performance of an Underlying Fund that represents an alternative or non-traditional investment strategy is generally expected to have low to moderate correlation with the performance of traditional equity and fixed income investments over long-term periods, the actual performance of such Underlying Fund may be correlated with those traditional investments over short- or long-term periods. Should there be periods when such Underlying Fund's performance is correlated with those traditional investments, any intended diversification effect of including such alternative or non-traditional Underlying Fund as part of an asset allocation strategy may not be achieved, thereby resulting in increased volatility of an asset allocation strategy that includes the Underlying Fund.

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.

• Regulatory Impact Risk: Certain financial instruments are subject to extensive government regulation, which may change frequently and impact a fund significantly.

• Short Exposure Risk: When a fund takes a short position using derivative instruments in anticipation of a decline in the market price (i.e., spot price or spot rate) of the underlying reference asset, such as entering into a derivative contract to sell a currency at a predetermined price for future delivery (forward foreign currency contract) in anticipation of a decline in the market price of the underlying currency, it is subject to the risk that the reference asset will increase in value, resulting in a loss. Such loss is theoretically unlimited. Short positions also may expose the fund to leverage risk.

PL Portfolio Optimization Conservative Fund: Mid-Capitalization Companies Risk and Short Sale Risk are deleted from the Principal risks from holdings in Underlying Funds subsection.

PL Portfolio Optimization Moderate-Conservative Fund: Inflation-Indexed Debt Securities Risk and Short Sale Risk are deleted from the Principal risks from holdings in Underlying Funds subsection.

PL Portfolio Optimization Moderate Fund: Short Sale Risk is deleted from the Principal risks from holdings in Underlying Funds subsection and the following is added:

• High-Yield or "Junk" Securities Risk: High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), potentially less liquid, and subject to a greater risk of loss, that is they are more likely to default than higher rated securities.

PL Portfolio Optimization Aggressive Fund: The following is added to the Principal risks from holdings in Underlying Funds subsection:

• U.S. Government Securities Risk: Not all U.S. government securities are backed or guaranteed by the U.S. government and different U.S. government securities are subject to varying degrees of credit risk. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. 

PL Short Duration Income Fund, PL Income Fund, PL Strategic Income Fund, PL Floating Rate Income Fund, and PL High Income Fund:

Effective October 1, 2012, the Advisor Class Service Plan was terminated and the related 0.25% service fee imposed under that plan was eliminated. All references and information relating to the Advisor Class Service Plan were deleted. For each Fund, the Advisor Share Class column in the Annual fund operating expenses table and expense Examples ("Fee Tables") was updated with the below. All other information in the Fee Tables, including related footnotes, has not changed.

The second sentence of the second paragraph of each PL Portfolio Optimization Fund's Principal investment strategies subsection is replaced with the following:

Within the broad asset classes of debt and equity, the fund diversifies its holdings by investing in Underlying Funds that represent a variety of investment styles and security types, including alternative or non-traditional investment strategies. Alternative or non-traditional investment strategies generally are expected to have low to moderate correlation to traditional equity and fixed income investments and, as a result, may offer diversification benefits.

In the same subsection, the following is added as the fourth paragraph:

The portion of the fund invested in alternative or non-traditional investment strategies may be allocated to Underlying Funds that, in turn, invest in equity or debt securities or other instruments, which may include, among others:

• Forward foreign currency contracts;

• Foreign currency options;

• High yield debt securities;

• Swaps (such as interest rate, cross-currency, total return and credit default swaps);

• Futures on securities, indexes, currencies and other investments; and

• Precious metals-related equity securities.

In the same subsection, the first sentence of the current fourth paragraph is replaced with the following:

The fund may also, at any time invest in Underlying Funds that hold other debt or equity securities or other instruments. 

The following is added to each PL Portfolio Optimization Fund's Principal risks from holdings in Underlying Funds subsection:

• Correlation Risk: While the performance of an Underlying Fund that represents an alternative or non-traditional investment strategy is generally expected to have low to moderate correlation with the performance of traditional equity and fixed income investments over long-term periods, the actual performance of such Underlying Fund may be correlated with those traditional investments over short- or long-term periods. Should there be periods when such Underlying Fund's performance is correlated with those traditional investments, any intended diversification effect of including such alternative or non-traditional Underlying Fund as part of an asset allocation strategy may not be achieved, thereby resulting in increased volatility of an asset allocation strategy that includes the Underlying Fund.

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.

• Regulatory Impact Risk: Certain financial instruments are subject to extensive government regulation, which may change frequently and impact a fund significantly.

• Short Exposure Risk: When a fund takes a short position using derivative instruments in anticipation of a decline in the market price (i.e., spot price or spot rate) of the underlying reference asset, such as entering into a derivative contract to sell a currency at a predetermined price for future delivery (forward foreign currency contract) in anticipation of a decline in the market price of the underlying currency, it is subject to the risk that the reference asset will increase in value, resulting in a loss. Such loss is theoretically unlimited. Short positions also may expose the fund to leverage risk.

PL Portfolio Optimization Conservative Fund: Mid-Capitalization Companies Risk and Short Sale Risk are deleted from the Principal risks from holdings in Underlying Funds subsection.

PL Portfolio Optimization Moderate-Conservative Fund: Inflation-Indexed Debt Securities Risk and Short Sale Risk are deleted from the Principal risks from holdings in Underlying Funds subsection.

PL Portfolio Optimization Moderate Fund: Short Sale Risk is deleted from the Principal risks from holdings in Underlying Funds subsection and the following is added:

• High-Yield or "Junk" Securities Risk: High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), potentially less liquid, and subject to a greater risk of loss, that is they are more likely to default than higher rated securities.

PL Portfolio Optimization Aggressive Fund: The following is added to the Principal risks from holdings in Underlying Funds subsection:

• U.S. Government Securities Risk: Not all U.S. government securities are backed or guaranteed by the U.S. government and different U.S. government securities are subject to varying degrees of credit risk. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. 

PL Short Duration Income Fund, PL Income Fund, PL Strategic Income Fund, PL Floating Rate Income Fund, and PL High Income Fund:

• Short Exposure Risk: When a fund takes a short position using derivative instruments in anticipation of a decline in the market price (i.e., spot price or spot rate) of the underlying reference asset, such as entering into a derivative contract to sell a currency at a predetermined price for future delivery (forward foreign currency contract) in anticipation of a decline in the market price of the underlying currency, it is subject to the risk that the reference asset will increase in value, resulting in a loss. Such loss is theoretically unlimited. Short positions also may expose the fund to leverage risk.

PL Portfolio Optimization Conservative Fund: Mid-Capitalization Companies Risk and Short Sale Risk are deleted from the Principal risks from holdings in Underlying Funds subsection.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.

This supplement revises the Pacific Life Funds Class A, B, C, I, R and Advisor Shares prospectus dated July 1, 2012 as supplemented September 28, 2012 (Prospectus), and must be preceded or accompanied by the Prospectus. The changes within this supplement are effective as of the date of commencement of operations for the PL Currency Strategies Fund, PL Absolute Global Return Fund, and PL Precious Metals Fund (expected to be December 7, 2012), unless otherwise noted. Remember to review the Prospectus for other important information.

Disclosure Changes to the Fund Summaries section

PL Portfolio Optimization Conservative Fund, PL Portfolio Optimization Moderate-Conservative Fund, PL Portfolio Optimization Moderate Fund, PL Portfolio Optimization Moderate-Aggressive Fund and PL Portfolio Optimization Aggressive Fund (the "PL Portfolio Optimization Funds"):

Each PL Portfolio Optimization Fund's Annual fund operating expenses table and expense Examples are replaced with the following:

¹  The expense information has been restated to reflect current fees.

²  The investment adviser has contractually agreed to limit certain "fund operating expenses" incurred by the fund that exceed an annual rate of 0.15% through 6/30/2015, and 0.30% from 7/1/2015 through 6/30/2023. The agreement will terminate: (i) if the investment advisory agreement is terminated, or (ii) upon ninety days' prior written notice by the Pacific Life Funds. The investment adviser may recoup amounts reimbursed in future periods, not to exceed 3 years from the end of the fiscal year in which the reimbursement took place, provided that the recoupment would not cause the fund to exceed the expense cap.

The second sentence of the second paragraph of each PL Portfolio Optimization Fund's Principal investment strategies subsection is replaced with the following:

Within the broad asset classes of debt and equity, the fund diversifies its holdings by investing in Underlying Funds that represent a variety of investment styles and security types, including alternative or non-traditional investment strategies. Alternative or non-traditional investment strategies generally are expected to have low to moderate correlation to traditional equity and fixed income investments and, as a result, may offer diversification benefits.

In the same subsection, the following is added as the fourth paragraph:

The portion of the fund invested in alternative or non-traditional investment strategies may be allocated to Underlying Funds that, in turn, invest in equity or debt securities or other instruments, which may include, among others:

• Forward foreign currency contracts;

• Foreign currency options;

• High yield debt securities;

• Swaps (such as interest rate, cross-currency, total return and credit default swaps);

• Futures on securities, indexes, currencies and other investments; and

• Precious metals-related equity securities.

In the same subsection, the first sentence of the current fourth paragraph is replaced with the following:

The fund may also, at any time invest in Underlying Funds that hold other debt or equity securities or other instruments. 

The following is added to each PL Portfolio Optimization Fund's Principal risks from holdings in Underlying Funds subsection:

• Correlation Risk: While the performance of an Underlying Fund that represents an alternative or non-traditional investment strategy is generally expected to have low to moderate correlation with the performance of traditional equity and fixed income investments over long-term periods, the actual performance of such Underlying Fund may be correlated with those traditional investments over short- or long-term periods. Should there be periods when such Underlying Fund's performance is correlated with those traditional investments, any intended diversification effect of including such alternative or non-traditional Underlying Fund as part of an asset allocation strategy may not be achieved, thereby resulting in increased volatility of an asset allocation strategy that includes the Underlying Fund.

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.

• Regulatory Impact Risk: Certain financial instruments are subject to extensive government regulation, which may change frequently and impact a fund significantly.

• Short Exposure Risk: When a fund takes a short position using derivative instruments in anticipation of a decline in the market price (i.e., spot price or spot rate) of the underlying reference asset, such as entering into a derivative contract to sell a currency at a predetermined price for future delivery (forward foreign currency contract) in anticipation of a decline in the market price of the underlying currency, it is subject to the risk that the reference asset will increase in value, resulting in a loss. Such loss is theoretically unlimited. Short positions also may expose the fund to leverage risk.

PL Portfolio Optimization Moderate-Conservative Fund: Inflation-Indexed Debt Securities Risk and Short Sale Risk are deleted from the Principal risks from holdings in Underlying Funds subsection.

The fund may also, at any time invest in Underlying Funds that hold other debt or equity securities or other instruments. 

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The following is added to each PL Portfolio Optimization Fund's Principal risks from holdings in Underlying Funds subsection:

• Correlation Risk: While the performance of an Underlying Fund that represents an alternative or non-traditional investment strategy is generally expected to have low to moderate correlation with the performance of traditional equity and fixed income investments over long-term periods, the actual performance of such Underlying Fund may be correlated with those traditional investments over short- or long-term periods. Should there be periods when such Underlying Fund's performance is correlated with those traditional investments, any intended diversification effect of including such alternative or non-traditional Underlying Fund as part of an asset allocation strategy may not be achieved, thereby resulting in increased volatility of an asset allocation strategy that includes the Underlying Fund.

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.

• Regulatory Impact Risk: Certain financial instruments are subject to extensive government regulation, which may change frequently and impact a fund significantly.

Such loss is theoretically unlimited. Short positions also may expose the fund to leverage risk.

The second sentence of the second paragraph of each PL Portfolio Optimization Fund's Principal investment strategies subsection is replaced with the following:

Within the broad asset classes of debt and equity, the fund diversifies its holdings by investing in Underlying Funds that represent a variety of investment styles and security types, including alternative or non-traditional investment strategies. Alternative or non-traditional investment strategies generally are expected to have low to moderate correlation to traditional equity and fixed income investments and, as a result, may offer diversification benefits.

In the same subsection, the following is added as the fourth paragraph:

The portion of the fund invested in alternative or non-traditional investment strategies may be allocated to Underlying Funds that, in turn, invest in equity or debt securities or other instruments, which may include, among others:

• Forward foreign currency contracts;

• Foreign currency options;

• High yield debt securities;

• Swaps (such as interest rate, cross-currency, total return and credit default swaps);

• Futures on securities, indexes, currencies and other investments; and

• Precious metals-related equity securities.

In the same subsection, the first sentence of the current fourth paragraph is replaced with the following:

The fund may also, at any time invest in Underlying Funds that hold other debt or equity securities or other instruments. 

The following is added to each PL Portfolio Optimization Fund's Principal risks from holdings in Underlying Funds subsection:

• Correlation Risk: While the performance of an Underlying Fund that represents an alternative or non-traditional investment strategy is generally expected to have low to moderate correlation with the performance of traditional equity and fixed income investments over long-term periods, the actual performance of such Underlying Fund may be correlated with those traditional investments over short- or long-term periods. Should there be periods when such Underlying Fund's performance is correlated with those traditional investments, any intended diversification effect of including such alternative or non-traditional Underlying Fund as part of an asset allocation strategy may not be achieved, thereby resulting in increased volatility of an asset allocation strategy that includes the Underlying Fund.

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.

• Regulatory Impact Risk: Certain financial instruments are subject to extensive government regulation, which may change frequently and impact a fund significantly.

• Short Exposure Risk: When a fund takes a short position using derivative instruments in anticipation of a decline in the market price (i.e., spot price or spot rate) of the underlying reference asset, such as entering into a derivative contract to sell a currency at a predetermined price for future delivery (forward foreign currency contract) in anticipation of a decline in the market price of the underlying currency, it is subject to the risk that the reference asset will increase in value, resulting in a loss. Such loss is theoretically unlimited. Short positions also may expose the fund to leverage risk.

PL Portfolio Optimization Moderate Fund: Short Sale Risk is deleted from the Principal risks from holdings in Underlying Funds subsection and the following is added:

• High-Yield or "Junk" Securities Risk: High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), potentially less liquid, and subject to a greater risk of loss, that is they are more likely to default than higher rated securities.

The investment adviser has contractually agreed to limit certain "fund operating expenses" incurred by the fund that exceed an annual rate of 0.15% through 6/30/2015, and 0.30% from 7/1/2015 through 6/30/2023. The agreement will terminate: (i) if the investment advisory agreement is terminated, or (ii) upon ninety days' prior written notice by the Pacific Life Funds. The investment adviser may recoup amounts reimbursed in future periods, not to exceed 3 years from the end of the fiscal year in which the reimbursement took place, provided that the recoupment would not cause the fund to exceed the expense cap.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The second sentence of the second paragraph of each PL Portfolio Optimization Fund's Principal investment strategies subsection is replaced with the following:

Within the broad asset classes of debt and equity, the fund diversifies its holdings by investing in Underlying Funds that represent a variety of investment styles and security types, including alternative or non-traditional investment strategies. Alternative or non-traditional investment strategies generally are expected to have low to moderate correlation to traditional equity and fixed income investments and, as a result, may offer diversification benefits.

In the same subsection, the following is added as the fourth paragraph:

The portion of the fund invested in alternative or non-traditional investment strategies may be allocated to Underlying Funds that, in turn, invest in equity or debt securities or other instruments, which may include, among others:

• Forward foreign currency contracts;

• Foreign currency options;

• High yield debt securities;

• Swaps (such as interest rate, cross-currency, total return and credit default swaps);

• Futures on securities, indexes, currencies and other investments; and

• Precious metals-related equity securities.

In the same subsection, the first sentence of the current fourth paragraph is replaced with the following:

The fund may also, at any time invest in Underlying Funds that hold other debt or equity securities or other instruments. 

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The following is added to each PL Portfolio Optimization Fund's Principal risks from holdings in Underlying Funds subsection:

• Correlation Risk: While the performance of an Underlying Fund that represents an alternative or non-traditional investment strategy is generally expected to have low to moderate correlation with the performance of traditional equity and fixed income investments over long-term periods, the actual performance of such Underlying Fund may be correlated with those traditional investments over short- or long-term periods. Should there be periods when such Underlying Fund's performance is correlated with those traditional investments, any intended diversification effect of including such alternative or non-traditional Underlying Fund as part of an asset allocation strategy may not be achieved, thereby resulting in increased volatility of an asset allocation strategy that includes the Underlying Fund.

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.

• Regulatory Impact Risk: Certain financial instruments are subject to extensive government regulation, which may change frequently and impact a fund significantly.

• Short Exposure Risk: When a fund takes a short position using derivative instruments in anticipation of a decline in the market price (i.e., spot price or spot rate) of the underlying reference asset, such as entering into a derivative contract to sell a currency at a predetermined price for future delivery (forward foreign currency contract) in anticipation of a decline in the market price of the underlying currency, it is subject to the risk that the reference asset will increase in value, resulting in a loss. Such loss is theoretically unlimited. Short positions also may expose the fund to leverage risk.

PL Portfolio Optimization Moderate Fund: Short Sale Risk is deleted from the Principal risks from holdings in Underlying Funds subsection and the following is added:

• High-Yield or "Junk" Securities Risk: High yield securities are typically issued by companies that are highly leveraged, less creditworthy or financially distressed and are considered to be mostly speculative in nature (high risk), potentially less liquid, and subject to a greater risk of loss, that is they are more likely to default than higher rated securities.

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund.

The investment adviser may recoup amounts reimbursed in future periods, not to exceed 3 years from the end of the fiscal year in which the reimbursement took place, provided that the recoupment would not cause the fund to exceed the expense cap.

The second sentence of the second paragraph of each PL Portfolio Optimization Fund's Principal investment strategies subsection is replaced with the following:

Within the broad asset classes of debt and equity, the fund diversifies its holdings by investing in Underlying Funds that represent a variety of investment styles and security types, including alternative or non-traditional investment strategies. Alternative or non-traditional investment strategies generally are expected to have low to moderate correlation to traditional equity and fixed income investments and, as a result, may offer diversification benefits.

In the same subsection, the following is added as the fourth paragraph:

The portion of the fund invested in alternative or non-traditional investment strategies may be allocated to Underlying Funds that, in turn, invest in equity or debt securities or other instruments, which may include, among others:

• Forward foreign currency contracts;

• Foreign currency options;

• High yield debt securities;

• Swaps (such as interest rate, cross-currency, total return and credit default swaps);

• Futures on securities, indexes, currencies and other investments; and

• Precious metals-related equity securities.

In the same subsection, the first sentence of the current fourth paragraph is replaced with the following:

The fund may also, at any time invest in Underlying Funds that hold other debt or equity securities or other instruments. 

The following is added to each PL Portfolio Optimization Fund's Principal risks from holdings in Underlying Funds subsection:

• Correlation Risk: While the performance of an Underlying Fund that represents an alternative or non-traditional investment strategy is generally expected to have low to moderate correlation with the performance of traditional equity and fixed income investments over long-term periods, the actual performance of such Underlying Fund may be correlated with those traditional investments over short- or long-term periods. Should there be periods when such Underlying Fund's performance is correlated with those traditional investments, any intended diversification effect of including such alternative or non-traditional Underlying Fund as part of an asset allocation strategy may not be achieved, thereby resulting in increased volatility of an asset allocation strategy that includes the Underlying Fund.

• Non-Diversification Risk: An Underlying Fund that is classified as non-diversified may invest a greater percentage of its assets in a single issuer or a fewer number of issuers than a diversified fund. This increases potential price volatility and the risk that its value could go down because of the poor performance of a single investment or a small number of investments.

• Regulatory Impact Risk: Certain financial instruments are subject to extensive government regulation, which may change frequently and impact a fund significantly.

• Short Exposure Risk: When a fund takes a short position using derivative instruments in anticipation of a decline in the market price (i.e., spot price or spot rate) of the underlying reference asset, such as entering into a derivative contract to sell a currency at a predetermined price for future delivery (forward foreign currency contract) in anticipation of a decline in the market price of the underlying currency, it is subject to the risk that the reference asset will increase in value, resulting in a loss. Such loss is theoretically unlimited. Short positions also may expose the fund to leverage risk.

PL Portfolio Optimization Aggressive Fund: The following is added to the Principal risks from holdings in Underlying Funds subsection:

• U.S. Government Securities Risk: Not all U.S. government securities are backed or guaranteed by the U.S. government and different U.S. government securities are subject to varying degrees of credit risk. There is risk that the U.S. government will not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.

The agreement will terminate: (i) if the investment advisory agreement is terminated, or (ii) upon ninety days' prior written notice by the Pacific Life Funds.

[1] The expense information has been restated to reflect current fees.

[2] The investment adviser has contractually agreed to limit certain "fund operating expenses" incurred by the fund that exceed an annual rate of 0.15% through 6/30/2015, and 0.30% from 7/1/2015 through 6/30/2023. The agreement will terminate: (i) if the investment advisory agreement is terminated, or (ii) upon ninety days' prior written notice by the Pacific Life Funds. The investment adviser may recoup amounts reimbursed in future periods, not to exceed 3 years from the end of the fiscal year in which the reimbursement took place, provided that the recoupment would not cause the fund to exceed the expense cap.
