<u>In the section entitled</u> *<u>Control Persons of Sub-Advisers,</u>* <u>the disclosure pertaining to DIFA for the SCEF,</u> <u>on page 77, is deleted in its entirety and replaced with the following:</u>

*Nomura Investments Fund Advisers ("NIFA"), 100 Independence, 610 Market Street, Philadelphia, Pennsylvania, 19106:* NIFA is a series of Nomura Investment Management Business Trust ("NIMBT"), which is a Delaware statutory trust. NIMBT is a subsidiary of Nomura Holding America Inc. ("NHA"). NHA is a wholly owned subsidiary of Nomura Holdings, Inc., a publicly traded Japanese company.

<u>In the section disclosing Portfolio Manager Compensation, the disclosure pertaining to DIFA, on page 96,</u> <u>is deleted in its entirety and replaced with the following:</u> 

*Nomura Investments Fund Advisers ("NIFA").* Each portfolio manager's compensation consists of a combination of base salary, an incentive profit-share tied to performance and long-term equity. Salaries are determined by a comparison to industry data prepared by third parties to ensure that portfolio manager salaries are in line with salaries paid at peer investment advisory firms.

Each named portfolio manager is eligible to receive an annual cash bonus. The bonus pool is determined by the revenues associated with the products a portfolio manager manages. Various members of the team have the ability to earn a percentage of the bonus pool with the most senior contributor generally having the largest share. The pool is allotted based on subjective factors (50%) and objective factors (50%). The primary objective factor is the one-, three- and five-year performance of the funds managed relative to the performance of the appropriate Morningstar, Inc. peer groups and the performance of institutional composites relative to the appropriate indexes. Three- and five-year performance is weighted more heavily, and there is no objective award for a fund whose performance falls below the 50th percentile for a given period of time.

Individual allocations of the bonus pool are based on individual performance measurements, both objective and subjective, as determined by senior management.

Portfolio managers participate in retention programs for alignment of interest purposes.

<sup>●</sup>

A portion of a portfolio manager's retained profit-share may be notionally exposed to the return of certain funds within Nomura Asset Management ("Nomura") pursuant to the terms of a Notional Investment Plan. The retained amount will vest in equal tranches over a designated period after the date of investment.

<sup>●</sup>

A portion of a portfolio manager's retained profit-share may be invested in a Nomura retained equity plan. Subject to vesting conditions, vesting and release of the shares occurs in a designated period after the date of investment.

In addition, portfolio managers may also participate in benefit plans and programs available generally to all similarly situated employees.

**IV. UPDATES TO PROXY VOTING GUIDELINES**

Effective July 3, 2025, the description of GuideStone Capital Management's LLC proxy voting guidelines in "Appendix C - Description of GuideStone Capital Management, LLC's Proxy Voting Guidelines" are deleted in their entirety and replaced with the following:

**Appendix C — Description of GuideStone Capital Management, LLC's Proxy Voting Guidelines**

Provided below is a description of the proxy voting guidelines of GuideStone Capital Management, LLC (the "Adviser").

**GENERAL PROXY VOTING GUIDELINES** 

The Adviser has adopted general guidelines for voting proxies as summarized below. In keeping with its fiduciary obligations, the Adviser reviews all proposals, even those that may be considered to be routine matters. Although these guidelines are to be followed as a general policy, in all cases each proxy and proposal (including both management and shareholder proposals) will be considered based on the relevant facts and circumstances on a case-by-case basis. The Adviser may deviate from the general policies and procedures when it determines that the particular facts and circumstances warrant such deviation to protect the best interests of the Funds and Fund shareholders. These guidelines cannot provide an exhaustive list of all the issues that may arise, nor can the Adviser anticipate all future situations. Corporate governance issues are diverse and continually evolving, and the Adviser devotes significant time and resources to monitor these changes.

**THE ADVISER'S PROXY VOTING GUIDELINES**

These guidelines have been reviewed by various members of the Adviser's organization, including portfolio management and the Adviser's officers.

In general, the Adviser will cast proxy votes FOR proposals that the Adviser reasonably believes encourage alignment of corporate actions with the Funds' faith-based investing policy guidelines, in accordance with GuideStone Financial Resources stated policy, ("FBI policy") so as to allow a Fund to continue to hold companies' securities that the Adviser believes offer financial benefits to the Fund, and the Adviser will cast proxy votes AGAINST proposals having the opposite effect, or where the Adviser does not have adequate objective facts available to it to make a reasonably informed decision as to whether the proposal is in the best interest of the Fund.

The following guidelines reflect what the Adviser believes to be good corporate governance and behavior:

**Board of Directors:** The election of directors and an independent board are key to good corporate governance. Directors are expected to be competent individuals, and they should be accountable and responsive to shareholders. The Adviser supports independent boards of directors, and believes that boards should be sufficiently independent from management to ensure effective supervision of management, that board composition should ensure that boards are appropriately sized and that directors add value through specific skills. The Adviser believes that key committees such as audit, nominating and compensation committees should be comprised of independent directors. The Adviser believes that directors should be sufficiently responsive to investor input, and accountable to shareholders, including through transparency of the company's governance practices and regular board elections.

v

------

In evaluating its vote for directors, the Adviser will consider the individual's qualifications, his or her ability to devote sufficient time to the board and his or her independence from management, as well as the overall composition of the board. As it relates to the composition of a board, the Adviser will consider current best practices and governance structures. Consideration will be given to the different qualifications and expertise of each director and the relevance of their experience to the company's operations, how representative the board is of the company's operations and other factors deemed relevant to that specific situation. Additionally, the Adviser will consider withholding votes from directors chairing or serving on committees which in its view have not been sufficiently responsive to shareholder concerns.

The Adviser will generally vote for director nominees, except under certain circumstances, including but not limited to those addressed herein. The Adviser will generally vote against management efforts to classify a board and will generally support proposals to declassify the board of directors. The Adviser will consider voting against or withholding votes from directors who have attended less than 75% of meetings without a valid reason. The Adviser will generally vote against or withhold from the directors, members of the governance committee or the full board if the company's governing documents impose undue restrictions on shareholders' ability to amend the bylaws. The Adviser will generally vote against or withhold from members of the audit committee if the company shows evidence of problematic audit-related practices, including poor accounting practices that rise to a level of serious concern*.* The Adviser will vote case-by-case on proposals on director and officer indemnification, liability protection and exculpation and will consider the stated rationale for the proposed change. In control situations, the Adviser will consider the specific circumstances of the situation. In general, the Adviser will focus on the protection of minority shareholder rights, and the history of the exercise of control by the controlling shareholder(s).

In the event of a contested election, the Adviser will review a number of factors in making a decision, including management's track record, the company's financial performance, qualifications of candidates on both slates and the strategic plan of the dissidents and/or shareholder nominees.

**Audit-Related:** The Adviser will closely scrutinize the independence, role and performance of auditors. On a case-by-case basis, the Adviser will examine proposals relating to non-audit services and non-audit fees, and proposals related to auditor indemnification and limitation of liability. The Adviser will vote against or withhold from members of an audit committee in situations where there is persuasive evidence that the audit committee entered into an inappropriate indemnification agreement with its auditor that limits the ability of the company, or its shareholders, to pursue legitimate legal recourse against the audit firm. The Adviser will vote against the ratification of auditors when there is clear and compelling evidence of a lack of independence, accounting irregularities or negligence attributable to the auditors.

**Shareholder Rights and Defenses:** The Adviser will vote case-by-case on advance notice proposals, giving support to those proposals which allow shareholders to submit proposals/nominations as close to the meeting date as reasonably possible. The Adviser will vote against proposals giving the board exclusive authority to amend the bylaws, and vote case-by-case on proposals giving the board the ability to amend the bylaws in addition to shareholders. The Adviser will generally vote for proposals to opt out of control share acquisition statutes unless doing so would enable the completion of a takeover that would be detrimental to shareholders, vote against proposals to amend the charter to include control share acquisition provisions and vote for proposals to restore voting rights to the control shares. The Adviser will generally vote for proposals to adopt anti-greenmail charter or bylaw amendments or otherwise restrict a company's ability to make greenmail payments and will vote case-by-case on anti-greenmail proposals when they are bundled with other charter or bylaw amendments.

The Adviser generally supports proposals that require shareholder rights plans ("poison pills") to be subject to a shareholder vote. The Adviser will closely evaluate shareholder rights plans, including management proposals to ratify a shareholder rights plan, on a case-by-case basis, to determine whether or not they warrant support. The

vi

------

Adviser will vote case-by-case on proposals regarding proxy voting mechanics, taking into consideration whether implementation of the proposal is likely to enhance or protect shareholder rights. Specific issues covered under the policy include, but are not limited to, confidential voting of individual proxies and ballots, confidentiality of running vote tallies and the treatment of abstentions and/or broker non-votes in the company's vote-counting methodology. While a variety of factors may be considered in each analysis, the guiding principles are transparency, consistency and fairness in the proxy voting process. The Adviser will generally vote against proposals to require a supermajority shareholder vote. The Adviser will vote case-by-case on proposals to adopt fair price provisions, evaluating factors such as the vote required to approve the proposed acquisition, the vote required to repeal the fair price provision and the mechanism for determining the fair price. The Adviser will generally vote against fair price provisions with shareholder vote requirements greater than a majority of disinterested shares. The Adviser will review a company's proposal to reincorporate to a different state on a case-by-case basis taking into consideration financial and corporate governance concerns, including reason for incorporation, comparison of company's governance practices and provisions prior to and following reincorporation and comparison of corporation laws of original state and destination state. The Adviser will support reincorporation when the economic factors outweigh any neutral or negative governance changes. The Adviser will generally support strong rights for shareholders as it relates to calling special meetings and acting by written consent.

**Capital/Restructuring:** The Adviser realizes that a company's financing decisions have a significant impact on its shareholders, particularly when they involve the issuance of additional shares of common or preferred stock or the assumption of additional debt. The Adviser will carefully review, on a case-by-case basis, proposals by companies to increase authorized shares and the purpose for the increase. The Adviser will generally not vote in favor of dual-class capital structures unless the company discloses a compelling reason for the dual-class structure, such as the intention to use the new class for financing purposes with minimal or no dilution to current shareholders in both the short and long term. The Adviser will vote on a case-by-case basis on proposals to increase the number of authorized shares of preferred stock that are used for general corporate purposes, but will generally vote against the issuance of preferred shares if the company discloses no specific use for the shares. The Adviser will review proposals seeking preemptive rights on a case-by-case basis, taking into consideration the size of the company, the shareholder base and the liquidity of the stock.

**Management and Director Compensation:** A company's equity-based compensation plan should be in alignment with the performance of the company, with emphasis on long-term shareholder value. The Adviser evaluates plans on a case-by-case basis by considering several factors to determine whether the plan is fair and reasonable. The Adviser will generally oppose plans that have the potential to be excessively dilutive and will almost always oppose plans that are structured to allow the repricing of underwater options or plans that have an automatic share replenishment ("evergreen") feature. The Adviser will generally support employee stock option plans in which the purchase price is at least 85% of fair market value, the offering period is 27 months or less and when potential dilution is 10% or less.

Severance compensation arrangements will be reviewed on a case-by-case basis, although the Adviser will generally oppose "golden parachutes" that are considered excessive or include tax gross-ups.

The Adviser will generally support holding say-on-pay votes annually. The Adviser will consider ISS's analysis of the plan, the alignment of pay and performance, the overall structure of the plan, the metrics used to judge performance and management performance. The Adviser will generally seek strong disclosure of the basis and rationale for pay decisions. Any discretionary elements of the compensation plan will be reviewed on the basis of sound judgement. Repricing of compensation awards, retroactive adjustments favoring management or any other provision or practice deemed to be egregious and present a significant risk to investors will lead to strong consideration of a vote against the compensation decision.

vii

------

**Social and Environmental Issues:** The Adviser believes that environmental and social issues can have significant impact on a company's performance over time. Companies may face significant financial, legal and reputational risks resulting from environmental and social practices, or negligent oversight of environmental and social issues. Appropriate oversight and handling of such issues can benefit corporate culture and performance over time.

The Adviser will generally vote case-by-case, examining whether implementation of the proposal is likely to enhance or protect shareholder value, while seeking to encourage alignment of corporate actions with the FBI policy.

The Adviser will generally vote case-by-case on proposals seeking a company's endorsement of principles that support a particular public policy position. The Adviser will consider whether the principles align with its Christian values, whether the principles is in the best interest of shareholders and whether endorsing the set of principles may require a company to take a stand on an issue that is beyond its own control and may limit its flexibility with respect to future developments.

The Adviser will generally vote against proposals restricting a company from making charitable contributions. The Adviser will generally vote case-by-case on proposals requesting a report on company or company supplier labor and/or human rights standards and policies, unless such information is already publicly disclosed, and will generally vote case-by-case on proposals requesting that a company conduct an assessment of the human rights risks in its operations or in its supply chain, or report on its human rights risk assessment process. The Adviser will generally vote for shareholder proposals seeking to limit the sale of tobacco, alcohol, gambling services, tetrahydrocannabinol (THC) products and conscious altering products and will vote for shareholder proposals that seek a review of a company's involvement with pornography. The Adviser will vote for resolutions supporting stronger governance in healthcare companies, vote for proposals increasing transparency of lending practices and vote for proposals asking for reports on company policies related to the sale of mature-rated video games. The Adviser will vote on shareholder proposals that address sanctity of life issues in a manner consistent with the biblical principles of the Southern Baptist Convention on abortion and sanctity of life issues. The Adviser will generally vote in support of resolutions that foster a culture of respect for people who hold diverse religious and ideological viewpoints in all aspects of their business.
