solutions, thereby simpl ifying their investment manager relationships. A first example of this approach in action is the successful launch of Mid Cap Fund I, the first fund of a new Mid Cap Fund Series during 2021. Mid Cap Fund I reached its €2.2 billion hard cap after a swift fundraising process with approximately 80% of capital raised from existing Fund Investors. A second example of this approach in action is the launch of NextGen Fund I, the first fund of our new NextGen Fund Series launched in 2021. Antin also offers co-investment opportunities in which a Fund Investor or other investors commit capital to a specific transaction alongside an Antin Fund. Structured through a vehicle managed by Antin, co-investments are used primarily to syndicate larger investments held by Antin Funds, in order to manage the relevant Antin Fund’s exposure to such investment and risks. Co-investments are a means for Fund Investors to gain access to supplementary investment opportunities. Antin’s co investment vehicles do not generate management fees or carried interest. Antin has established a consistent track record of delivering co-investment opportunities, which makes Antin an attractive partner for Fund Investors. To date, total capital raised for co-investments amounts to approximately €4.1 billion across ten Antin Fund portfolio companies in various Antin Funds (1) . Co-investments are included in Antin’s reported AUM figures but excluded from reported fee-paying assets under management (“ FPAUM ”) figures. 1.4.3 Fund administration In 2011, Antin decided to internalise fund administration activities and create a fund administration hub in charge of management control, oversight, fund compliance as well as middle office tasks related to fund administration and business support for all its funds in Luxembourg. For this purpose, AISL 2 (2) , was established in Luxembourg in order to implement the day-to-day administration tasks which have been delegated by the Fund Managers (as defined in Section 1.7 " Regulatory Environment ") to AISL 2. Antin believes that the centralisation of administrative functions within AISL 2 provides numerous benefits, including increased scalability given the shared resources and knowledge which reside within the hub and increased quality of service due to the deep specialisation and enhanced operations.

Source: Company information. Over the medium to long-term, it is Antin’s intention to further grow the share of capital raised from regions outside of Europe. Significant progress towards this goal has already been made over time when comparing Flagship Fund I (2008 vintage) and Mid Cap Fund I (2021 vintage) where the share of capital raised from Europe has decreased from 93% to 55%. Antin believes it is an attractive and credible partner to its Fund Investors. Antin Funds have historically delivered consistent returns across economic cycles, which is a key driver of demand from current and potential Fund Investors. To further develop and grow its Fund Investor base Antin has devised a three-pillar growth strategy. First, Antin aims to retain current Fund Investors by deepening existing relationships through high-quality service. Establishing new relationships requires a long-term perspective and patience. Once established, however, relationships with Fund Investors can last for many years. A loyal investor base provides stability and visibility for subsequent fundraising campaigns as demonstrated by the 85% average re-investment rate achieved by Antin for the Flagship Fund Series. Moreover, many Fund Investors consider themselves to be under-allocated to the infrastructure asset class compared to their own targets. As such, there remains a substantial growth opportunity from existing Fund Investors. This has already been substantiated in prior fundraising campaigns with average commitment size per Fund Investor increasing by 35% between 2015 and 2021. Secondly, Antin sees an opportunity to grow its Fund Investor base by expanding in certain geographies. Whilst its Fund Investor base is well established in Europe thanks to Antin’s roots and history, Antin believes there is a significant opportunity for further expansion in under-penetrated markets, most notably North America and Asia-Pacific. Recognising that proximity to these markets is a key success factor, Antin has recently made various senior hires to reinforce its investor relations capabilities in North America. Further, Antin established an office in Singapore in 2021. The purpose of this office is to enable Antin to better serve Antin’s large and diversified Fund Investor base and establish new relationships across Asia-Pacific. Thirdly, Antin operates a multi-strategy platform, enabling Fund Investors to get access to different infrastructure investment
