Liability valuation on several bases
Projected benefit cash flows are discounted on funding, accounting, guarantee and buyout bases, so the board sees how the same promises look under each purpose and which assumptions drive the differences.

Spatial financeDonde el capital se encuentra con la amenaza, la exposición y la transición
Actuarial mathematics turns a promise to pay into a number a board can manage: the present value of benefits, the contributions needed to fund them and their sensitivity to rates, inflation and survival. For institutional funds it is the measure of the liability side, and every assumption it rests on is a judgement that must be stated.
Actuarial mathematics applies probability, statistics and financial theory to measure and price contingent risks, particularly in insurance and pensions. It determines reserves and premiums for uncertain future obligations. In capital markets and investment and society and human development, actuarial methods determine whether risks can be insured and at what cost. They help assess accumulation of correlated losses across portfolios and regions. The canonical description is on el bien común CTIM.
Projected benefit cash flows are discounted on funding, accounting, guarantee and buyout bases, so the board sees how the same promises look under each purpose and which assumptions drive the differences.
Base tables are adjusted to scheme experience and combined with improvement models, and the liability is revalued under alternative improvement paths to show longevity sensitivity.
Contributions, expected returns and benefit outgo are projected forward to show how a deficit is closed over the recovery period, and how the path changes under stressed returns or a weaker sponsor.

En los seis pilares, bajo la dirección de Nexus Consortium
Assumptions are tested through experience studies and actual-versus-expected analysis. Independent actuarial review checks methods and results.
| Verificación | Cómo se hace |
|---|---|
| Actual versus expected analysis | Deaths, retirements and withdrawals are compared with what the assumptions implied, and persistent gaps prompt a change of assumption |
| Analysis of surplus | The change in funding between valuations is decomposed into returns, rates, experience and assumption changes, and the residual is reported |
| Sensitivity reporting | Liabilities are restated under shifts in discount rate, inflation and longevity so each assumption’s weight is visible |
| Independent actuarial review | Methods and assumptions are reviewed by an actuary not involved in the valuation, under professional standards |
Historical experience may not reflect emerging or correlated risks. Long-tail liabilities are sensitive to assumptions about future trends.
