| H. | Significant market disruptions, such as those caused by pandemics, natural or environmental disasters, war, acts of terrorism, political or regulatory conditions, or other events, can adversely affect local and global markets and normal market operations. Any such disruptions could have an adverse impact on the value of the fund’s investments and fund performance. |
| I. | Operating segments are components of an entity that engage in business activities, have discrete financial information available, and have their operating results regularly reviewed by a chief operating decision maker (“CODM”). The fund is considered a single segment. Vanguard’s chief executive officer, chief investment officer, and chief financial officer, who are also officers of the fund, as well as the fund’s chief financial officer collectively act as the CODM. Vanguard has established various management committees to assist the CODM with overseeing aspects of the fund’s daily operations. Through these committees, the CODM manages the fund’s operations to achieve a single investment objective, as detailed in its prospectus, through the execution of the fund’s investment strategies. When assessing segment performance and making decisions about segment resources, the CODM relies on the fund’s portfolio composition, total returns, expense ratios and changes in net assets which are consistent with the information contained in the fund’s financial statements. Segment assets, liabilities, income, and expenses are also detailed in the accompanying financial statements. |
| J. | Management has determined that no other subsequent events or transactions occurred through the date the financial statements were issued that would require recognition or disclosure in these financial statements. |

Item 11: Statement Regarding Basis for Approval of Investment Advisory Contracts.
Trustees Approve Advisory Arrangement - Mega-Cap Growth Index Fund
A majority of independent trustees of the board of Vanguard Mega Cap Growth Index Fund (Trustees) has approved a restructuring of the fund’s management structure whereby the Vanguard Group, Inc. (Vanguard) will now provide investment advisory services to the fund through its subsidiary, Vanguard Fund Management LLC (VPM). The trustees determined that approving the advisory arrangements was in the best interests of the fund and its shareholders.
The Trustees based their decision upon an evaluation of VPM’s investment staff, fund management process, and performance. This evaluation included information provided by Vanguard’s Oversight and Manager Search team, which is responsible for fund and advisor oversight and product management. The Trustees considered the factors discussed below, among others. However, no single factor determined whether to approve the arrangement. Rather, it was the totality of the circumstances that drove the Trustee’s decisions.
Nature, extent, and quality of services
The Trustees considered the quality of the investment management services to be provided to the fund and took into account the organizational depth and stability of Vanguard and VPM. The Trustees considered that Vanguard has been managing investments for more than four decades. The Strategic Equity Index Management team (SE), now within VPM, adheres to the same sound, disciplined investment management process and has considerable experience, stability and depth. In its management of other Vanguard passive and active equity funds and funds, the team has a track record of consistent performance as a result of its disciplined investment processes. SE has specific expertise and experience managing U.S. style-box, sector, and smart-beta index strategies, effectively navigating index reconstitutions and mitigating transactions costs to deliver tight tracking error while opportunistically seeking to add excess returns through sophisticated trading strategies and superior access to corporate actions.
The Trustees concluded that VPM’s experience, stability, depth, and performance, among other factors, warranted approval of the advisory arrangement.
Investment performance
The Trustees determined that VPM’s Strategic Equity Index Management team, in its management of Vanguard funds, including the fund, has a track record of consistent performance and disciplined investment processes. The Trustees concluded the performance was such that the advisory arrangements warranted approval.
Cost
The Trustees concluded that the fund’s expense ratio will remain below the average expense ratio charged by funds in its peer group and that the fund’s advisory expenses will also continue to be below the peer-group average.
The Trustees do not conduct a profitability analysis of Vanguard in providing investment advisory services through VPM because of Vanguard’s unique structure. Unlike most other mutual fund management companies, Vanguard is owned by the funds it oversees.
The benefit of economies of scale
The Trustees concluded that the fund’s arrangement with Vanguard, and services rendered through VPM, ensure that the fund will realize economies of scale as it grows, with the cost to shareholders declining as fund assets increase.
The Trustees will consider whether to renew the advisory arrangement again after a one-year period.
