Terms of use
The NXS-GRX platform as designed: product lines, access layers, audiences, the user lifecycle and the journeys that run each step. Availability is stated per capability; nothing here is offered as a rating, warning, benchmark, certification or advice. Target service levels are proposals for design review.
NIS outputs are indicator composites with published methodology, not opinions on the creditworthiness of any entity, debt or issuer, and use no rating-category scale (EU Regulation 1060/2009 and equivalents).
NIS indices are not licensed as benchmarks for financial instruments, financial contracts or fund performance; any such use needs a separate licence and an administrator assessment under the EU and UK Benchmarks Regulations and the IOSCO principles.
NIS outputs are Nexus-modelled; they are not official statistics and are not endorsed by any source publisher.
NIS outputs must not be used to evaluate natural persons (creditworthiness, insurance pricing, access to essential services); such uses are high-risk under the EU AI Act Annex III.
