The claim reserves are calculated for homogeneous portfolios of insurance contracts via actuarial methods which are well known form literature. The basis of the classic reserving methods is built by two dimensional matrices, the run off – triangles. They are generated via accumulation of claim data.

Details. Two model are estimated in the double chain ladder framework as with the function. In this case the inflation parameter (inflat) is estimated from the incurred triangle (see BF adjustment in the description of the BDCL method in MartinezMiranda, Nielsen and Verrall 2013).The predicted reserve using these estimates is different from the incurred reserve.
The Chain Ladder Method (CLR) is a method for calculating the claims reserve requirement in an insurance company's financial chain ladder method (CLM) is used by insurers to ...
Traditional reserve estimation methodsTraditional reserve estimation methods can be roughly classified into two main groups: geometric and geostatistical methods (Henley, 2000). The geometric methods comprise the block methods (triangle, regular, squares, rectangular, polygonal and irregular or geometric blocks), the methods of profiles ...
This supply uncertainty affects the prediction of economic value from the initial valuation of a mining project through mine planning, design and production scheduling. This book is the first of its kind, presenting stateoftheart stochastic simulation and optimization .
Definitions. Estimation of reserves is done under conditions of uncertainty. The method of estimation is called deterministic if a single best estimate of reserves is made based on known geological, engineering, and economic data. The method of estimation is called .
Section 4: Simulation Techniques to Estimate Confidence Intervals for IBNR Reserves In this section, a step by step guide for employing simulation techniques to calculate confidence intervals and fitting probability distributions to the claim data is presented.
The cutoff grade of valuable components delimits the complex ore reserves suitable for efficient mining. The cutoff grade optimization is conducted to maximize the net present value of products in mining projects. The investigations were realized by using the equivalent grade method, iterated grid ...
Resource Estimation. CIM definitions for mineral resources were used. Mineral resources were estimated at a cutoff grade of g/t Au. Mineral resources were estimated using a gold price of US 1,500 per ounce and an exchange rate of US = C A minimum mining width of four metres was used.

Resource and Reserve Estimates • IFRS has no specific reporting requirements for reserve estimates. • Most mining companies comment on resource/reserve estimates in F/S, MDA or Annual Reports. o Usually based on NI 43101 reports • Reserves often are the basis for depreciation and depletion PricewaterhouseCoopers LLP calculations.
