Proyectos de cumplimiento normativo en Estados Unidos
Ryder Scott tiene experiencia en la evaluación de reservas en todo el mundo. Esto incluye las directrices y reglamentos de información para una variedad de organizaciones y organismos reguladores. Independientemente del lugar del mundo en el que residan los activos de petróleo y gas de una empresa o del lugar en el que ésta desarrolle su actividad, si la empresa ofrece valores para su venta al público en el mercado de Estados Unidos (bolsa), éstos deben ajustarse a las normas de la Comisión de Seguridad e Intercambio de Estados Unidos (SEC). La misión de la SEC es principalmente proteger a los inversores, mantener unos mercados justos, ordenados y eficientes, y facilitar la formación de capital. Para ello, la SEC exige a las empresas que divulguen datos financieros significativos, de modo que todos los inversores tengan acceso a ciertos datos básicos sobre una inversión antes de comprarla y mientras la mantengan. Además, busque los documentos de la SEC en Buscador de la SEC. El público está informado sobre las reservas de petróleo y gas de una empresa mediante la presentación de determinados formularios de la SEC que se ponen a disposición del público, entre los que destacan los siguientes:
- Formulario 10-K
- Un informe anual que ofrece una visión general de la actividad y la situación financiera de una empresa. Las empresas domiciliadas en Estados Unidos utilizan este formulario.
- Formulario 20-F
- Un informe anual que tiene una finalidad similar a la del formulario 10-K. Los emisores privados extranjeros utilizan este formulario.
- Formulario 40-F
- Un informe anual que tiene una finalidad similar a la del formulario 10-K. Las empresas domiciliadas en Canadá utilizan este formulario.
- Formularios S-1, S-3 y S-8
- Formulario de registro de nuevos valores
Ryder Scott goza de una importante y larga tradición en la realización de evaluaciones de reservas que se ajustan a la normativa de la SEC. Esta experiencia queda demostrada por el gran número de referencias a Ryder Scott en estos documentos de acceso público.
