Editorial Independence Policy

We subscribe to standards of editorial independence adopted by the Institute for Nonprofit News (INN):

Our organization retains full authority over editorial content to protect the best journalistic and business interests of our organization. We maintain a firewall between news coverage decisions and sources of all revenue. Acceptance of financial support does not constitute implied or actual endorsement of donors or their products, services, or opinions.

We accept gifts, grants, and sponsorships from individuals and organizations for the general support of our activities, but our news judgments are made independently and not on the basis of donor support.

Our organization may consider donations to support the coverage of particular topics, but our organization maintains editorial control of the coverage. We will cede no right of review or influence of editorial content.

Our organization will make public all donors who give a total of $5,000 or more per year. We will accept donations in accordance with INN’s Membership Standards.

Donor Transparency Policy 

We are committed to transparency in every aspect of funding our organization. Accepting financial support does not mean we endorse donors or their products, services, or opinions.

Our news judgments are made independently — not based on or influenced by donors or any revenue source. 

We accept gifts, grants, and sponsorships from individuals, organizations, and foundations to help with our general operations, coverage of specific topics, and special projects. As a nonprofit project that operates as a public trust, we do not pay certain taxes. We may receive funds from standard government programs offered to nonprofits or similar businesses.

We make public all revenue sources and donors who give a total of $5,000 or more per year. We will not accept donations from sources who, as deemed by our executive leadership, present a conflict of interest with our work or compromise our independence.
