IBNR

Adjustment to observed deaths in a given time period to account for deaths that have occurred but have not been reported due to the time lag in reporting systems or errors and incomplete information available from reporting sources regarding deaths. (ASOP No. 48)

IGT

A transfer of public funds between governmental entities (for example, county government to state government or state university hospital to state Medicaid agency). (Medicaid Managed-Care Capitation – Rate Development and Certification)

Illustrated Scales

A scale of nonguaranteed elements currently being illustrated that is not more favorable to the policyholder than the lesser of the disciplined current scale or the currently payable scale.

Illustration Actuary

An actuary who is appointed in accordance with the requirements set forth in the Model.

Immediate Gain Actuarial Cost Methods

An actuarial cost method under which actuarial gains and losses are included as part of the unfunded actuarial accrued liability of the pension plan, rather than as part of the normal cost of the plan.

Impaired Mortality

A mortality assumption that has been adjusted for impairments. (ASOP No. 48)

Impairment

A health factor or condition that tends to increase an insured’s probability of death. (ASOP No. 48)

Implementation

An executable form of the model. Examples of implementation may include, but not be limited to, a computer program, database, spreadsheet or any combination thereof. (Modeling)

Incentive Payments

Incurral Date

The date a claim is determined to be a liability of the organization in accordance with the terms of the health benefit plan. For health benefit plans where the claim must exceed a minimum threshold, for example where there is a deductible or elimination period, the incurral date may be the date claims begin to accumulate toward the threshold. (ASOP No. 5)

Incurred but not Reported (IBNR) Deaths

Adjustment to observed deaths in a given time period to account for deaths that have occurred but have not been reported due to the time lag in reporting systems or errors and incomplete information available from reporting sources regarding deaths. (ASOP No. 48)

Incurred Claims

A death that has taken place, whether known or not known. (Exposure Draft, Proposed ASOP Life Settlements Mortality)

Incurred Deaths

Independent Living Units

Living quarters designed for residents capable of living independently. A resident could receive home health care in the independent living unit, but a resident who needs full-time health care on either a temporary or permanent basis is normally transferred to the health center.

Indeterminate Premium Policies

Life and health insurance policies under which the insurer is obligated to provide coverage for an extended period of time, and under which premiums may vary at the discretion of the insurer. (ASOP No. 10)

Individual

In this standard, the word refers both to individual life insurance and annuity contracts and to individual-type contracts issued under a “group” umbrella of any trust which does not have discretion to select the insurer(s) on behalf of all individual policyholders. (ASOP No. 1)

Individual Aggregate Actuarial Cost Method

A method under which the actuarial present value of each increment of an individual’s projected benefits is allocated on a level basis over the future earnings or service of the individual between the age at which such increment is first recognized and the exit age(s). The portion of this actuarial present value allocated to a valuation year is called the normal cost. The actuarial value of assets is deemed to be assigned to individuals on a reasonable and consistent basis; for example, each individual’s share may be the accumulation of his or her prior normal costs and any prior actuarial gains (losses) allocated to the individual. Actuarial gains (losses) are allocated to individuals in proportion to the assigned actuarial value of assets, or on any other reasonable and consistent basis. The actuarial accrued liability for an individual equals the assigned portion of the actuarial value of assets. (ASOP No. 4)

Individual Level Actuarial Cost Method

A method under which the actuarial present value of each increment of an individual’s projected benefits is allocated on a level basis over the future earnings or service of the individual between the age at which such increment is first recognized and the exit age(s). The portion of this actuarial present value allocated to a valuation year is called the normal cost. Each individual’s portion of the actuarial accrued liability should be determined on a consistent basis, usually as the retrospective accumulation of the individual’s prior actuarial accrued liability and prior normal cost, using the valuation actuarial assumptions. (ASOP No. 4)

Individual Policies

Any policy (or contract) that is defined as an individual policy under state insurance law or by the terms of the policy. Any certificate issued under any other policy that is sold to a passive trust but is marketed to individuals is also defined as an individual policy for purposes of this standard. (ASOP No. 33)

Individual Spread Gain Actuarial Cost Method

A method under which the actuarial present value of each increment of an individual’s projected benefits is allocated on a level basis over the future earnings or service of the individual between the age at which such increment is first recognized and the exit age(s). The portion of this actuarial present value allocated to a valuation year is called the normal cost. The actuarial value of assets is deemed to be assigned to individuals on a reasonable and consistent basis; for example, each individual’s share may be the accumulation of his or her prior normal costs and any prior actuarial gains (losses) allocated to the individual. Actuarial gains (losses) are allocated to individuals in proportion to the assigned actuarial value of assets, or on any other reasonable and consistent basis. The actuarial accrued liability for an individual equals the assigned portion of the actuarial value of assets. (ASOP No. 4)

Inflation

General economic inflation, defined as price changes over the whole of the economy.

Information Date

Initial Assets

The assets allocated to a closed block at its inception. The assets of the closed block may be either of the following: (a) a distinct segment of assets (which may contain either 100% or a specified fraction of each designated asset) associated exclusively with the closed block; or (b) a defined share of a larger segment of assets. Such larger segment may also contain assets associated with participating business sold after the date of conversion. Such defined share will vary from time to time according to the methodology specified in the operating rules. (ASOP No. 33)

The obligations ascribed to the closed block at its inception by the operating rules. (ASOP No. 33)
