Périodicité de l'opération :
The ILC is calculated as the weighted sum of three indices: - Consumer Price Index, excluding tobacco and rents, published for all households in Metropolitan France and French Overseas Departments (IPCL) - Cost-of-construction (ICC) index - Retail Trades Index, in value, corrected for seasonal variations and calendar effects (ICAVaCD). These three indices are used to calculate the ILC with the following weighting: Quarterly Commercial Lease Index (ILC) = 50% mIPCL + 25% mICC + 25% mICAVaCD. Each of the three indices comprising the ILC is calculated as a mean: - Over 12 consecutive months for consumer prices (mIPC) and the turnover (mICAVaCD), which are monthly indices - Over 4 quarters for the cost of construction, an index calculated on a quarterly basis (mICC). In order to calculate these means, the last month (or quarter) considered corresponds to the last month of the quarter (or to the quarter) of calculation of the ILC. The ILC, like each of its constituent indices, is expressed in relation to the reference 100 in the first quarter of 2008.
