Why this pack exists

Invaren — converting DB pension rights into DC — is the most technically complex and politically sensitive part of the WTP transition. Every participant cohort is affected differently. The conversion methodology choice determines winners and losers, impacts intergenerational fairness, and ultimately determines whether the pension fund can defend its decision to DNB and the participant council.

This pack provides a structured, defensible approach to invaren impact assessment. Instead of ad-hoc actuarial memos and board debates, you get production-ready workbooks for scenario modeling, cohort impact analysis, nFTK adequacy testing, and documented go/no-go decision criteria that satisfy both prudential and governance expectations.

What's included

Invaren Scenario Comparison Workbook

Structured comparison of 4 conversion methods: standard historical accrual, VBA reserve attribution, modified hybrid, and member fund preference model. Analyzes 8 dimensions including methodology, capital allocation, compensation mechanism, intergenerational impact, complexity, reversibility, and DNB preference signals.

Cohort Impact Modeling Tool

Models current DB value vs. projected DC value across 12 participant cohorts (active by age band, deferred, retirees). Calculates impact percentage and adequacy status for each cohort. Supports sensitivity analysis on discount rates, return assumptions, and allocation parameters.

nFTK Adequacy Test Framework

Evaluates 15 nFTK elements under current DB regime and new DC regime: dekkingsgraad equivalent, indexation capacity, benefit reduction risk, replacement ratio, intergenerational fairness, and guarantee equivalents. Maps each element to DNB thresholds and risk monitoring requirements.

Go/No-Go Decision Checklist

15-point board-level checklist covering cohort impact validation, compensation design, participant council advice, DNB pre-notification, actuarial sign-off, legal opinion, communication plan, and appeal procedures. Tracks completion and sign-off by responsible parties.

Participant Council Briefing Pack

Executive summary for participant council covering why invaren is needed, which methods are being evaluated, which cohorts are most affected, mitigation measures (compensation, guarantees, transition periods), and decision timelines. Includes FAQ and escalation procedure.

DNB Pre-Notification Template

Formal notification letter covering invaren method choice, cohort-by-cohort impact analysis, nFTK adequacy assessment, go/no-go criteria met, participant council advice (if obtained), and request for DNB feedback. Includes required appendices and data schedules.

Implementation Roadmap & Communication Plan

12-month implementation schedule covering decision approval, systems preparation, participant notification, objection/appeal window, data validation, and execution. Defines communication touchpoints, timing, and escalation procedures for identified risks.

Who this is for

This pack is built for Dutch pension funds executing WTP transitions where invaren is the chosen path. It's essential for funds evaluating multiple conversion methods, funds with diverse cohorts experiencing unequal impact, and funds seeking to strengthen their governance and defensibility of invaren decisions to both DNB and participant councils.

Frequently asked questions

What is invaren and why does WTP require it?

Invaren is the process of converting accumulated defined benefit pension rights (accrued and vested) into defined contribution entitlements. WTP requires invaren because DB pensions are unsustainable under long-term trends (longevity, low interest rates, nFTK volatility). Converting to DC transfers investment and longevity risk to members, allowing the fund to operate sustainably. Invaren is the legal mechanism that preserves accrued value while moving to a new risk-sharing structure.

How do I choose between the 4 invaren methods in the pack?

The pack models 4 methods with different implications for cohort impact, complexity, and DNB defensibility. Standard historical accrual is simplest but may create winners/losers. VBA reserve attribution is actuarially rigorous but complex. Modified hybrid balances complexity and fairness. Member fund preference maximizes choice but requires higher administrative burden. Your choice depends on your fund's actuarial principles, participant demographics, and tolerance for implementation complexity.

What if some cohorts show negative impact? Can we still proceed?

Negative impact for certain cohorts (typically late-career active members and deferred members) is common and expected. The pack helps you design compensation mechanisms (transitional guarantees, supplements, or adjustments) that mitigate impact within acceptable bounds. DNB and the participant council will focus on whether mitigation is proportionate and defensible, not on achieving zero impact for all cohorts.

How does this relate to participant communication?

The pack includes a participant council briefing template and communication plan. You'll use the scenario analysis to explain why invaren is necessary, the cohort impact table to show who is affected and how, and the go/no-go checklist to demonstrate governance rigor. Clear communication with participant councils early in the process is critical to avoiding prolonged conflicts and formal objections.

Does Diletti support implementation beyond the pack?

Absolutely. The pack provides the analytical and governance framework; for invaren-specific data extraction, actuarial modeling, legal structuring, or participant council facilitation, we offer advisory engagements alongside every pack. Contact us to discuss phased support from decision through execution.
