ASSET VALUATION: The component age year was not set to a default value when a new section was created. This resulted in an error message when the user moved away from the screen even if they made no changes. This parameter is now initialised but should be reviewed by the user when entering asset valuation data. |

BUDGET OPTIMISATION: Analyses that exceeded the limits for performing budget optimisation using the EBM-32 method (see HDM-4
documentation for more details) did not produce the desired optimisation results. This error has now been fixed. |

Fixed(2.01) |
| KB200034 |
BUDGET OPTIMISATION: The unconstrained and optimised work programmes do not take account of differences in the works and output currencys if the conversion factor between then is not equal to 1. This can lead to incorrect optimisation or incorrect interpretation of the result. A work around to this problem is available. <read more> |

MULTI-YEAR FORWARD PROGRAMMING: The salvage value was not being calculated and included in the analysis. |

| KB200016 |
WORK ITEMS: The preparatory work quantities and costs were incorrectly calculated for resealing, overlay, and inlay operation types. This resulted in the preparatory costs being many times higher than expected, therefore effecting the results of the economic analysis of studies. These errors have now been corrected and it is recommended that studies are re-run to determine the impact of the corrected calculations. |

| KB200015 |
ASSET VALUATION: An omission was found in the Asset Valuation specification which resulted in the asset value of a pavement being incorrectly computed following an improvement standard. The specification has been amended and the software implementation updated accordingly. |

MULTI-CRITERIA ANALYSIS: The multi-criteria analysis did not take account of which criterion was selected as the base criterion. This could lead to incorrect results. |

WORK ITEMS: The works quantity for the maintenance reconstruction work item was being reported as 0 m^2. This has been corrected and the correct area of reconstruction is now reported. |

| KB200032 |
MULTI-CRITERIA ANALYSIS: The results dialog for Multi-criteria Analysis (MCA) did not display the project alternative/section alternative name so it was difficult to interpret the results. The display of the results has been improved to display the name of the alternative in the column header and as a tool-tip. |
