Expatriate Data Terms

Customized Index — a goods and services index created to meet an organization's special needs.

Efficient Purchaser Index (EPI) — a comparison of the prices of goods and services between the home country and assignment location that assumes familiarity with local brands and shopping in local outlets in the assignment location.

European Union Weighting — method used in a goods and services index that averages the weighting patterns of European Union member countries.

Goods and Services — a representative sample, or market basket, of all items and services purchased in the following categories: food at home (meat, fish, and dairy; groceries; fruits and vegetables); tobacco and alcohol; personal care, furnishings and household operations; clothing; medical care; recreation; transportation (public and private); domestic service; and food away from home. The market basket is priced in both the home country and assignment location to determine cost differences and compute the goods and services index.

International Index — a goods and services index, for highly mobile employees, that has no link to any home-country weighting pattern.

Modified Index — a goods and services index from which full or partial categories of goods and services that are employer provided or protected are removed from the market basket and excluded from the index calculation.
