What's great about Mantle?

Our approach to this is different to many of our competitors as it involves no programming language. Most competitor administration platforms are at their heart decades old. The standard approach to benefit calculations was to code these using a programming language. This requires experts in that language and the output was a “black box” calculation that was then inserted back to the platform.

There are a number of obvious problems with this approach not least that the structure of the calculation can’t be “seen” or easily verified. Mantle uses a totally different approach. Our “open architecture” allows for administrators to code up benefits without the need for a programming language. The benefit calculation is constructed within Mantle and is 100% transparent. This simplifies testing, speeds up the on boarding process and reduces cost. It also means that Mantle is Pensions Dashboard ready.’

Mantle is one system, which comprises of:

— Administration
— Actuarial
— Liability modelling

It can be deployed administration only with a unified payroll and accounts capability. This creates efficiency and reduces costs.  The actuarial layer can be enabled meaning that one system can be used to administer the scheme, run actuarial calculations and even model liabilities from the same underlying data. Valuations can be run at the click of a button. The dashboard allows for a complete view of the scheme and how it’s performing. The liability modelling capability runs thousands of plausible future scenarios for the individual liabilities of every member of the scheme, time-stepped at annual intervals.

Mantle is a modern modular cloud-hosted system that solves a number of problems.

How to deliver the most efficient and member friendly administration experience?

How to integrate with actuarial systems?

How to efficiently model liabilities and scenarios?

We designed Mantle to be affordable for schemes with as few as 100 members. We believe small schemes and their members deserve the best products and services just as much as the larger schemes.

The result is a truly unified, modern platform ready to meet the needs of all schemes – that platform is Mantle.
