the unsecured inter-bank deposit market,
other unsecured deposit markets, including certificates of deposit and commercial paper, and

a contributor's observations of third party transactions in the markets described in point (a);
committed quotes;

interpolation or extrapolation from transactions data;
adjustments to reflect changes in the credit standing of the contributors and other market participants.
the administrator of an interest rate benchmark shall have in place an independent oversight committee. Details of the membership of that committee shall be made public, along with any declarations of any conflict of interest and the processes for election or nomination of its members;
the oversight committee shall hold no less than one meeting every four months and shall keep minutes of each such meeting;
the oversight committee shall operate with integrity and shall have all of the responsibilities provided for in Article 5(3).

the relative importance that shall be assigned to each criterion used in benchmark calculation, in particular the type of input data used and the type of criterion used to guide judgement so as to ensure the quality and integrity of the benchmark calculation;
criteria that identify the minimum amount of transaction data required for a particular benchmark calculation. If no such threshold is provided for, the reasons why a minimum threshold is not established shall be explained, including setting out the procedures to be used where no transaction data exist;
criteria that address the assessment periods where the submitted data fall below the methodology's recommended transaction data threshold or the requisite administrator's quality standards, including any alternative methods of assessment including theoretical estimation models. Those criteria shall explain the procedures to be used where no transaction data exist;
criteria for timeliness of contributions of input data and the means for such contributions of input data whether electronically, by telephone or otherwise;
criteria and procedures that address assessment periods where one or more contributors submit input data that constitute a significant proportion of the total input data for that benchmark. The administrator shall also define in those criteria and procedures what constitutes a significant proportion for each benchmark calculation;
criteria according to which transaction data may be excluded from a benchmark calculation.
the rationale for adopting a particular methodology, including any price adjustment techniques and a justification of why the time period or window within which input data is accepted is a reliable indicator of physical market values;

concluded and reported transactions;
bids and offers;
other information.
If concluded and reported transactions are not given priority, the reasons should be explained, as required in point 7(b).
employ sufficient measures designed to use input data submitted and considered in a benchmark calculation which are bona fide, meaning that the parties submitting the input data have executed, or are prepared to execute, transactions generating such input data and the concluded transactions were executed at arms-length from each other and particular attention shall be paid to inter-affiliate transactions;
establish and employ procedures to identify anomalous or suspicious transaction data and keep records of decisions to exclude transaction data from the administrator's benchmark calculation process;

employ a system of appropriate measures to ensure that contributors comply with the administrator's applicable quality and integrity standards for input data.
a concise explanation, sufficient to facilitate a benchmark subscriber's or competent authority's ability to understand how the calculation was developed including, at a minimum, the size and liquidity of the physical market being assessed (such as the number and volume of transactions submitted), the range and average volume and range and average of price, and indicative percentages of each type of input data that have been considered in a calculation; terms referring to the pricing methodology shall be included such as transaction-based, spread-based or interpolated or extrapolated; and
a concise explanation of the extent to which, and the basis upon which, any judgement including the exclusions of data which otherwise conformed to the requirements of the relevant methodology for that calculation, basing prices on spreads or interpolation, extrapolation, or weighting bids or offers higher than concluded transactions, if any, was used in any calculation.

Those procedures shall include, to the extent possible, provision for escalation of the inquiry by the administrator within the contributor's company. Controls shall include cross-checking market indicators to validate submitted information.
adopt and have in place explicit internal rules and guidelines for selecting assessors, including their minimum level of training, experience and skills, as well as the process for periodic review of their competence;
