Transaction Costs

A calculation engine developed by RiskConcile

The PRIIPs regulation requires a complete cost transparency for investment products in their Key Information Document (‘KID’). This includes disclosure of the implicit transaction costs of trading underlying instruments. 

To capture these implicit transaction costs, the regulator imposes the slippage or arrival price methodology. New products, or products for which insufficient data are available, can use the new PRIIPs methodology (half-spread).

With regards to MIFID, the ESMA expects alignment with the PRIIPs methodology for the ex-post transaction costs disclosure to investors. 

The European Supervisory Authorities recently confirmed that the arrival price methodology is there to stay.

Capture both explicit and implicit transaction costs.

Slippage or Arrival Price Methodology

Slippage is the difference between the arrival price and the execution price of a trade. Sourcing arrival prices requires large amounts tick history.

New PRIIPs Methodology

An estimation of the implicit costs can be made. This approximation uses the turnover at the asset-class level and the corresponding half bid-ask spread. This methodology is also known as the half-spread or portfolio turnover methodology.
