37 C.F.R. § 380.21
(a) Minimum fee for eligible Noncommercial Educational Webcasters. Each Noncommercial Educational Webcaster that did not exceed 160,000 total ATH for any individual channel or station for more than one calendar month in the immediately preceding calendar year and does not expect to make total transmissions in excess of 160,000 ATH on any individual channel or station in any calendar month during the applicable calendar year shall pay an annual, nonrefundable minimum fee in the amount set forth in paragraphs (a)(1) through (5) of this section (the “Minimum Fee”) for each of its individual channels, including each of its individual side channels, and each of its individual stations, through which (in each case) it makes Educational Transmissions, for each calendar year it makes Educational Transmissions subject to this subpart. For clarity, each individual stream (e.g., HD radio side channels, different stations owned by a single licensee) will be treated separately and be subject to a separate Minimum Fee. However, all of the streams of Digital Audio Transmissions of music programming by a Noncommercial Educational Webcaster, or by a group of affiliated Noncommercial Educational Webcasters, that are the same or have only immaterial variations (e.g., differences in station identification, acknowledgement of sponsors or occasional substitute programming) shall be treated as part of one channel or station for purposes of this section. For this purpose, two Noncommercial Educational Webcasters shall be considered affiliates if one is controlling, controlled by, or under common control with the other. This principle applies whether the streams are offered from only a single outlet or through multiple outlets (e.g., websites, broadcast radio station simulcasts, aggregators, mobile applications or other online locations where listeners can access music streaming). The Minimum Fee shall constitute the annual per channel or per station royalty for all Educational Transmissions totaling not more than 160,000 ATH in a month on any individual channel or station, and for Ephemeral Recordings to enable such Educational Transmissions. In addition, a Noncommercial Educational Webcaster electing the reporting waiver described in § 380.22(d)(1) shall pay a $100 annual fee (the “Proxy Fee”) to the Collective (for purposes of this subpart, the term “Collective” refers to SoundExchange, Inc.). The Minimum Fee for each year of the royalty period is:
(b) Consequences of unexpectedly exceeding the ATH cap. In the case of a Noncommercial Educational Webcaster eligible to pay royalties under paragraph (a) of this section that unexpectedly makes total transmissions in excess of 160,000 ATH on any individual channel or station in any calendar month during the applicable calendar year:
