The RASC Legacy Fund was established for the promotion and advancement of Society objectives. Use of this fund is governed by these guidelines:

• To finance endeavours leading to long-term growth in the capability of the Society to fulfill its objectives;
• To 'top up' special purpose funds which serve the objectives of the Society in the shorter term;
• To provide monies loaned to Centres or to the Society itself for projects that are related to their long-term growth, such as the construction of an observatory or building;
• To add to the principal of the endowment Fund.
