In a situation when the actuarial liability is less than the actuarial value of a pension fund’s assets, the measure of this value.

A valuation carried out by an actuary on a regular basis, in particular, to test future funding or current solvency of the value of the pension fund’s assets with its liabilities.

The person or entity whose responsibility, as a minimum, is to evaluate present and future pension liabilities in order to determine the financial solvency of the pension plan, following recognised actuarial and accounting methods

Are beds accommodating patients where the principal clinical intent is to do one or more of the following: manage labour (obstetric); cure illness or provide definitive treatment of injury; perform surgery; relieve symptoms of illness or injury (excluding palliative care);reduce severity of illness or injury; protect against exacerbation and/or complication of an illness and/or injury which could threaten life or normal functions; perform diagnostic or therapeutic procedures.

The number of staff employed in hospitals, where the primary focus of activity is on acute care, divided by the number of available beds.

Acute health conditions are characterised by sudden onset and are of finite duration. In addition, they tend to severely restrict the subject’s usual daily activities.

An ad valorem tariff is a charge levied on imports, defined in terms of a fixed percentage of value.

Capacity for evolutionary change.

Adaptation refers to changes in an organism’s structure or habits that help it adjust to its surroundings

Adapted products are products that are less polluting, at the time of their consumption and/or scrapping, than equivalent traditional products. In most cases, such products are more costly, and their production and consumption are usually encouraged by fiscal and other incentives.

The practice of identifying options to adapt to climate change and evaluating them in terms of criteria such as availability, benefits, costs, effectiveness, efficiency, and feasibility.

Is the adjustment made to equation- based projection over the forecasting period. For example, if an equation has under-predicted a variable in recent periods, then an "add factor" may be added to the equation if it is judged that the equation will under-predict over the forecast period as well. In short, add factors are equation- residuals applied over the forecast period.

Additional bonuses to base salary refer to additional payments that teachers may acquire in addition to the amount received on the basis of educational qualification and experience (salary scale). These bonuses may be awarded for teaching in remote areas, for participating in school improvement projects or special activities or for excellence in teaching performance.

The entry of the SEEA asset accounts that records the value of changes in stock level of mineral and energy resources due to new discoveries or reappraisals of the quantity and quality of previously known stocks; natural growth of non-cultivated biological resources.

Additives are non-hydrocarbon substances added to or blended with a product to modify its properties, for example, to improve its combustion characteristics.

Compounds added to or blended with oil products to modify their properties (octane, cetane, cold properties, etc.).

At current prices, the value of an aggregate is identical to the sum of the values of its components.

At current prices, the value of an aggregate is equal to the sum of its components. At constant prices, additivity requires this identity to be preserved for the extrapolated values of the aggregate and its components, when their values in some reference period are extrapolated to some other period using a set of interdependent volume index numbers, or, alternatively, when the values of an aggregate and its components in some period are deflated using a set of interdependent price index numbers based on some other period.

Additivity is a property pertaining to a set of interdependent index numbers related by definition or by accounting constraints under which an aggregate is defined as the sum of its components; additivity requires this identity to be preserved when the values of both an aggregate and its components in some reference period are extrapolated over time using a set of volume index numbers.

Food salt fortified with an adequate amount of iodine (15 ppm and above) to prevent iodine-deficiency disorder, including goitre, in adults and children and mental handicap in children.

Interference that is caused by a transmitter operating in an adjacent channel.

The currency conditions are similar to a foreign interest payment security (FIPS); however, the bonds have a floating interest rate and a put option.

Adjusted disposable income is derived from the disposable income of an institutional unit or sector by adding the value of the social transfers in kind receivable by that unit or sector and by subtracting the value of the social transfers in kind payable by that unit or sector.
