WIKIMEDIA FOUNDATION, INC. 
Notes to Consolidated Financial Statements 
June 30, 2024 and 2023 
 10 (Continued) 
The Foundation enters into contracts with its customers that may include promises to transfer multiple 
performance obligations such as API software subscription, professional service hours, and service 
level agreement (SLA) and support. The Foundation generally considers these to be one single 
performance obligation. Determining whether products and services are distinct performance 
obligations that should be accounted for separately or combined as one unit of accounting may require 
judgment.  
The transaction price is determined based on consideration to which the Foundation will be entitled in 
exchange for transferring services to the customer, as stated in the contract. The Foundation has 
determined that the contracts do not contain a significant financing component.  
Revenue is generally recognized ratably over the contract term as the performance obligation is 
satisfied. The Foundation’s contracts typically are non-cancelable and do not contain refund-type 
provisions. The Foundation typically invoices its customers annually and its payment terms provide that 
customers pay within 30 days of invoice. Amounts that have been invoiced are recorded in accounts 
receivable and in deferred revenue (within “Other Liabilities”) or revenue, depending on whether 
transfer of control to customers has occurred. 
Revenue derived from API software subscriptions and professional services  is reported within other 
income, net in the statement of activities. Deferred revenue, revenue, and billings for the years ended 
June 30, 2024 and 2023 are as follows. Deferred revenue is reported within other liabilities in the 
statement of financial position.  
2024 2023
Deferred revenue - beginning balance $ 1,660,000  1,560,000  
Billings 3,820,000  3,320,000  
Less revenue recognized (3,351,250) (3,220,000) 
Deferred revenue - ending balance $ 2,128,750  1,660,000  
 
(n) Leases 
Leases consist of a lease liability for the Foundation’s headquarters in San Francisco. The liability is 
equal to the present value of lease payments, which are fixed. The present value is calculated using a 
risk-free discount rate, determined using a period comparable with that of the lease term. The lease 
term in accordance with ASC 842 does not include options to extend as it is not reasonably certain that 
the option will be exercised. The Foundation determined during the year ended June 30, 2024 not to 
renew the lease.
