Methodology and Reference


Methodology and Specifications

Clearly defined and transparent methodologies are the backbone of Platt's price assessment processes. Platt’s methodologies provide detailed descriptions and explanations of how we assess the market value of commodities so that customers and other interested parties understand those processes. In this section, we post documentation by commodity and region for all published price assessments and indices. Select an item from the drop-down list to learn more.


Subscriber Notes / Methodology Updates

Check here for any changes in methodology, specifications or price assessment descriptions that Platts publishes. In this section, we post proposed changes to methodologies for existing price points, new price assessment proposals, requests for feedback on proposed price assessment changes, and proposals to discontinue price assessments or indices. This section also includes announcements of upcoming events, and office closures which may affect the publication of prices, such as public holidays or weather emergencies.


New & Discontinued Price Symbols

Platts uses symbols to identify price assessments and other numeric data delivered via Platts’ real-time, Dispatch and other data services. Once price assessment changes and new third-party data series are announced (see Subscriber Notes), new price symbols will provide the necessary details, including descriptions, frequency, currency, units of measure and other attributes.


Corrections

While Platts has an exceedingly low correction rate for its price assessments, corrections are inevitable given the sheer volume of information we publish. We issue corrections for price assessments as soon as discrepancies are identified, but only when a technical error has affected the price, or when a correction is issued by a third-party data source. Platts does not issue corrections to published price assessments to reflect information that may become available after publication.


Price Symbol and Page Directories

Platts’ symbol directories list Platts’ time-series price codes and related descriptive information grouped by commodity and data category. Page directories provide a page guide to Platts’ real-time news and alert services


Holiday Schedule

The Holiday Calendar is an in-depth annual compilation of the world's regional and national holidays, whose observation will impact the publishing of Platts' assessments, market reports and news wires.


Conversion Tables

The Platts conversion tables feature a wide range of conversions for use in calculations involving oil, electricity and other energy sources.
