Services in the area of property and casualty insurance are provided by BELTIOS P&C GmbH, a separate entity independent from BELTIOS GmbH.

BELTIOS P&C’s main focus is on the classical non-life actuarial areas of

  • Reserving
  • Risk modelling
  • Pricing

as well as the processes and workflows related to these activities. Our clients include primary insurers, reinsurers and captives.
Regulatory regimes such as Solvency II or Swiss Solvency Test (SST) require actuarial valuation and risk modelling to be integrated into risk management as well as accounting and reporting processes. In a constantly changing environment, new challenges keep arising, for instance related to IFRS 17. We at BELTIOS P&C support our clients both on the actuarial side and on the embedding of new processes into the landscape within the actuarial department and beyond.

Similar risk-modelling techniques can be applied to the benefit of medium-sized and large industrial enterprises in order to analyse the existing insurance programme, define the risk appetite and test alternative insurance scenarios for optimisation. A meaningful use of actuarial methods requires a certain amount of claims experience as data basis, i.e. a history of a certain number of individual losses. We assist our customers throughout the entire implementation, starting from the conceptual phase and establishment of data sources and ending with the model calibration and management reports.

Our clients benefit from the comprehensive experience of an established team and our focus on technically sound and customised solutions.


The classical topics of claims reserving, risk modelling and pricing are essential actuarial tasks in the insurance industry. Small and medium-sized companies as well as large insurers and groups increasingly aim to leverage actuarial models to obtain maximum business value added. A key requirement for this to happen is the communication with non-actuarial departments and the embedding of actuarial work into the company’s processes and system landscape.

To overcome the related challenges we offer support in the following areas:

Actuarial claims reserving

Reserve estimation

BELTIOS P&C developed its own web-based software RESTA for actuarial claims reserving. RESTA has been used by BELTIOS P&C’s actuaries on various assignments and is also available to be licenced by our customers.

RESTA’s features include the following:

  • User-friendly, with an intuitive user interface
  • Best-practice actuarial reserving methods such as
    • Chain Ladder
    • Additive Model (based on loss increments relative to exposure)
    • Bornhuetter-Ferguson
    • Tail estimation using curve-fitting
    • Weighting of different methods, by origin period, to obtain the selected estimate
    • A number of result summaries and charts supports the user in the validation and final selection of reserve estimates
  • Variation Analysis and estimation of the premium reserve under Solvency II
  • Reserve uncertainty can be measured analytically under the ultimate and the one-year view. RESTA also includes the simulation-based bootstrap approach which provides a result distribution “to ultimate” and, via the re-reserving method, a distribution of the one-year run-off result.
  • Customer-specific configurations are possible
  • Flexible input and output of data (for instance MS Excel™)
  • Best-practice standards in the areas of auditability, data security, and archiving
  • RESTA supports parallel accessing of models by several users and offers a state-of-the-art role system for different tasks such as modeller and reviewer. It is suitable for large-scale use in a complex organisational environment.
  • Continuous development, also in line with customers‘ requirements
