Facts And Circumstances Test
DURING 2018, AMATEUR RADIO DIGITAL COMMUNICATIONS ("ARDC") RECEIVED A SUBSTANTIAL PART OF ITS SUPPORT FROM THE GENERAL PUBLIC. HOWEVER, AS ARDC DOES NOT RECEIVE A LARGE AMOUNT OF PUBLIC SUPPORT, TWO DONORS' CONTRIBUTIONS OF OVER $7,000 CREATED EXCESS CONTRIBUTIONS AND CAUSED ARDC TO NOT MEET ITS PUBLIC SUPPORT OBLIGATIONS WITHOUT THE 10% FACTS AND CIRCUMSTANCES TEST. DURING 2018, ARDC DID NOT RECEIVE ANY OF ITS INCOME FROM GROSS INVESTMENT INCOME AND IS ENTIRELY SUPPORTED BY CONTRIBUTIONS FROM THE GENERAL PUBLIC, WHICH IT SOLICITS THROUGH ITS WEBSITE. FURTHER, THE MEMBERS OF ARDC'S BOARD OF DIRECTORS REPRESENTS THE BROAD PUBLIC INTERESTS SERVED BY THE MISSION OF THE ORGANIZATION. IT IS FOR THESE REASONS THAT ARDC MEETS ITS PUBLIC SUPPORT OBLIGATION UNDER THE 10% FACTS AND CIRCUMSTANCES TEST, AS A SMALL EXCESS CONTRIBUTION SHOULD NOT DISQUALIFY THE ORGANIZATION FROM REMAINING A 501(C)(3) PUBLIC CHARITY.

FORM 990, PART VI, SECTION A, LINE 4	THE BOARD OF DIRECTORS AMENDED ARDC'S BYLAWS DURING 2019.
FORM 990, PART VI, SECTION B, LINE 11B	THE BOARD WAS GIVEN A DRAFT OF THE 990 TO REVIEW BEFORE SUBMISSION.
FORM 990, PART VI, SECTION B, LINE 12C	ARDC REQUIRES ANNUAL SIGNOFF OF THE CONFLICT OF INTEREST STATEMENT.
FORM 990, PART VI, SECTION C, LINE 19	AMATEUR RADIO DIGITAL COMMUNICATIONS MAKES ALL ITS GOVERNING DOCUMENTS AND FINANCIAL STATEMENTS AVAILABLE TO THE PUBLIC BY REQUEST.
FORM 990, PART X, LINE 15 EXPLANATION OF IP ADDRESSES HELD	EVERY ORGANIZATION, PERSON, OR DEVICE ATTACHED TO THE INTERNET MUST HAVE AN INTERNET PROTOCOL ADDRESS IN ORDER TO FUNCTION AS PART OF THE NETWORK. INITIALLY PLENTIFUL AND FREELY AVAILABLE AT NO CHARGE, IN THE PAST DECADE THESE HAVE BECOME SCARCE AND THEIR AVAILABILITY SUBJECT TO MARKET FORCES. IN THE 1980'S, WHEN THE INTERNET WAS IN ITS INFANCY, INTERESTED PARTIES WERE GIVEN LARGE NUMBERS OF IP ADDRESSES AT NO COST BY THE INTERNET ASSIGNED NUMBERS AUTHORITY [IANA], A US GOVERNMENT CONTRACTOR, WITHOUT RESTRICTION. IT WAS ONLY NECESSARY TO EXPLAIN THAT ONE WANTED A BLOCK OF ADDRESSES TO RESEARCH AND EXPERIMENT WITH THE NEW EVOLVING NETWORK AND THEY WOULD BE MADE AVAILABLE. MOST OF THE PARTICIPANTS WERE RESEARCH UNIVERSITIES AND GOVERNMENT CONTRACTORS, OR THE MILITARY, OR SOME DEDICATED COMMUNICATIONS RESEARCH FIRMS. RESEARCH AND EXPERIMENTATION HAVE LONG BEEN A DRIVING FORCE IN THE FIELD OF AMATEUR ("HAM") RADIO. IN 1981, A SMALL GROUP OF CURIOUS "HAMS" REQUESTED AND RECEIVED A BLOCK OF 16 MILLION SUCH ADDRESSES FOR AMATEUR RADIO DIGITAL COMMUNICATION PURPOSES. THIS SEEMINGLY LARGE QUANTITY WAS IN FACT A COMMON SIZE OF SUCH AN ALLOCATION, DUE IN PART TO THE VAST NUMBER [SOME 4.2 BILLION] OF SUCH ADDRESSES AVAILABLE IN THE INTERNET, LIMITATIONS IN THE INTERNET EQUIPMENT OF THE PERIOD, AND HOW FEW ENTITIES WERE ACTUALLY EXPERIMENTING WITH THE INTERNET. THE ALLOCATION TO THIS GROUP OF AMATEUR RADIO ENTHUSIASTS IS DOCUMENTED IN THE INTERNET ENGINEERING PUBLICATION RFC790 FROM SEPTEMBER 1981, WHERE IT IS DESIGNATED THE AMPRNET. AS THIS GROUP BECAME MORE COHESIVE, IT BECAME KNOWN AS THE AMATEUR RADIO DIGITAL COMMUNICATIONS GROUP, FROM WHICH OUR CURRENT-DAY ORGANIZATION EVOLVED. BECAUSE THE ALLOCATION CAME AT NO COST AND THERE WAS NO DISCERNABLE MARKET FOR THE ADDRESSES AT THE TIME THEY WERE RECEIVED, THE ADDRESSES WERE ASSIGNED NO VALUE ON THE ORGANIZATION'S BALANCE SHEET. FOR MORE THAN 30 YEARS, IT HAS BEEN THE MISSION OF THIS ORGANIZATION TO SUPPORT AMATEUR RADIO RESEARCH AND EXPERIMENTATION WITH DIGITAL NETWORKING BY PROVIDING ADVICE, COORDINATION, AND PERHAPS MOST SIGNIFICANTLY, ASSIGNING IP ADDRESSES TO AMATEUR RADIO OPERATORS ANYWHERE IN THE WORLD WHO WANTED TO WORK WITH DIGITAL COMMUNICATIONS. THESE ASSIGNMENTS HAVE ALWAYS BEEN MADE AT NO CHARGE FROM OUT OF OUR INITIAL ALLOCATION OF 16 MILLION, AND ARE ESSENTIALLY LONG-TERM ZERO-COST LEASES OF THE ADDRESS BLOCKS. AS THE SUPPLY OF INTERNET ADDRESSES IS FINITE (AT MOST 4.2 BILLION) AND THE INTERNET HAS GROWN EXPLOSIVELY OVER THE PAST DECADE OR SO, THERE HAS BEEN A TIGHTENING OF THE SUPPLY OF INTERNET ADDRESSES. TODAY, IN 2019, THEY ARE IN FACT SCARCE. AS A RESULT, A MARKET IN SELLING AND RESELLING ADDRESSES HAS EMERGED. OUR ORGANIZATION, AMATEUR RADIO DIGITAL COMMUNICATIONS [ARDC] HAS RECENTLY BECOME AWARE OF THE MARKET VALUE OF THE ADDRESSES IT HOLDS. NOT LONG AGO, WE CONDUCTED A STUDY OF OUR UTILIZATION OF THOSE ADDRESSES AND CAME TO THE REALIZATION THAT WE HAD MANY MORE THAN ARE NEED TO SUPPORT ARDC USER COMMUNICATIONS. THEREFORE, OUR BOARD OF DIRECTORS HAS UNANIMOUSLY AGREED TO DIVEST ABOUT ONE QUARTER (25%, OR ABOUT 4 MILLION) OF THIS ASSET, AND HAS SOLD IT ON THE OPEN MARKET AND WILL USE THE INCOME TO FUND OUR CONTINUING MISSION OF SUPPORTING RESEARCH IN DIGITAL COMMUNICATIONS THROUGH VARIOUS PROGRAMS OF GRANTS, SUPPORTED RESEARCH PROJECTS, AND SCHOLARSHIPS. THE SALE OCCURRED IN 2019. THE REMAINING 75% (SOME 12 MILLION ADDRESSES) WILL BE RETAINED AND CONTINUE TO BE USED DIRECTLY IN OUR MISSION AS THEY LONG HAVE BEEN.
