For more information about the SEC's Notice and Access Proxy Rules, please visit: www.sec.gov/spotlight/proxymatters/e-proxy.shtml Check out our FAQs below: Why am I being asked to authorize my proxy? Your vote plays a meaningful role in the governance of ASIF and helps ensure that we have enough participation to formally hold the meeting. Authorizing your proxy ahead of time allows the meeting to proceed as scheduled and helps us avoid additional follow-up outreach. If we don't receive the required number of votes beforehand, we may need to delay the meeting and reconvene at a later date, which can increase both timing and administrative costs. Why am I receiving a notice of internet availability? The Securities and Exchange Commission ("SEC") permits companies to send the enclosed "Notice" instead of a full printed set of proxy materials. The Notice provides instructions on how to view your company's proxy materials, vote online and request a full set of printed materials by mail. There are several advantages to your company sending a notice instead of a full set of materials, including lowering your company's costs and reducing the environmental impact from printing and mailing full sets of proxy materials. How do I view the proxy materials online? Go to www.proxyvote.com and enter your control number to get started. Your control number can be found on the enclosed Notice. What if I prefer to receive a paper copy of the proxy materials? You can easily request a paper copy which will be mailed to you at no cost. Instructions on how to do so can be found in the Get informed before you vote section of the Notice. Can I receive proxy materials for future meetings by e-mail rather than receive a Notice? Yes you can. Go to www.proxyvote.com and make your choice in the Delivery Settings section.
