The IANA transition cost ICANN a total of $32 million, according to documentation released today.
The hefty bill was racked up from the announcment of the transition in March 2014 until the end of 2016, according to this presentation (pdf).
A whopping $15 million of the total went on lawyers.
Another $8.3 million went on other third-party services, including lobbying, PR and translation.
More than half of the overall expenses — $17.8 million — was incurred in ICANN’s fiscal 2016, which ended last June.
