Running IBNR results with multiple methods… Most health care actuaries use a variety of methods to estimate IBNR and the preferred method may be a combination of methods. For example, lag methods while commonly used, have the highest standard deviations. Thus, the use of a second method is suggested in order to obtain reasonable

Resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods (see below) used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.

ii.) Loss Reserve Triangles The loss reserving triangle is the standard method for maintaining loss data. While the entries vary for different methods, the use of the triangles is always the same. 12 months 24 months 36 months 48 months 60 months 2001 59,500 70,400 71,700 72,000 71,900 2002 64,200 76,700 77,600 77,700 2003 58,400 72,800 73,900

resource estimate is the critical fundamental foundation of all mining projects. All work done must be compliant with the relevant code i.e. SAMREC or JORC etc. Reserve estimates The reserve estimate gives an indication of the viability of the mineral resource. Calculation of the reserves will depend on the mining method, including an estimate on

There are different estimation methods (see below) used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available. A table displaying resource estimation method selection can be found below. Nearest Neighbour Method

· The development of geostatistics as an ore reserve estimation methodology emerged in France in early 1960 from the work of Matheron (1962) and was based on original studies by D.G. Krige functioning the optimal assigning of weights to the neighbouring sample values used in estimating the grade of blocks in South African gold mines.

· In addition for a UPR & PDR reserve estimation exercise the data should additionally consist of: Written, earned & unearned premium by line of business; Financial statements – claim, premium, expense, income statements Quality. Data quality is an important factor for the IBNR reserve estimation process as it directly impacts results obtained.
