The Rotary Foundation
In 1917 RI President Arch C Klumph started an "Endowment" fund with an initial donation of $26.50 for doing Good in the world, later transformed into The Rotary Foundation now worth more than $1b.A link HERE is available to take you straight to Rotary.org for the complete rundown of The Rotary Foundation, but for your convenience here below is a brief overview of the information.
There are 3 funds into which donations go, and they are PolioPlus, The Endowment Fund and the Annual Fund. All donations by individuals count towards a Paul Harris Recognition. A club (or another person/member) may donate the $1000 USD in another person's name to be able to present to them this recognition. The levels go from a plain Paul Harris pin right up to and including a 3 Ruby pin with many variations in between.
Another way to donate is to EREY which in plainspeak means Every Rotarian Every Year $100 USD and the Centurion $100 AUD.
There are many other ways of donating which is best researched for you to find the one which suits you best or speak to Foundation Director Derrick Marsden or PDG Geoff James for any further information you require.
