**SSASIM: PIADYNS . id**

Identifies set of PIA policy parameters specified on this row of table, so id value should be unique for each group of rows that has a collection of cal_year values (see below).

Valid values: 1 to 999999999 (nine digits), Integer

Source code: policy.h and policy.cpp

**SSASIM: PIADYNS . notes**

Describes specification of table row in free-form note.

Valid values: any ASCII text (Note: do not copy and paste from a word processor because of the possibility of embedded non-ASCII characters.)

Source code: notes are not read by the model

**SSASIM: PIADYNS . cal_year**

Identifies calendar year during which the PIA policy parameters specified on this table row are in effect. Calendar years for which no row exists have their non-PIA-fraction parameter values calculated by linear interpolation between the closest prior year and closest subsequent year for which table rows have been specified for this id. Non-PIA-fraction parameter values for years following the last specified year are taken to be equal to values in the last specified year.

Valid values: 1992 to (1992+RUN.num_years), Integer

Source code: policy.h and policy.cpp

**SSASIM: PIADYNS . adj_meth12**

Specifies which automatic adjustment method is applied to PIA fractions 1 and 2 (pia_frac_1 and pia_frac_2) for this cal_year. A value of one (1) implies no automatic adjustment of those PIA fractions; missing cal_year values are computed by interpolation and extrapolation in the same manner as non-PIA-fraction parameters (see cal_year for details). A value of two (2) implies automatic adjustment of those PIA fractions using the "price indexing" scheme used in the CSSS plan 2. A value of three (3) implies automatic adjustment of those PIA fractions using the fixed-rate-of-adjustment scheme used in the CSSS plan 3. A value of four (4) implies those PIA fractions are equal to their values in the prior year.

Valid values: 1 to 4, Integer

Source code: policy.h and policy.cpp

**SSASIM: PIADYNS . adj_fact12**

Specifies the automatic multiplicative adjustment factor used for this cal_year when the adj_meth12 is three (3); when adj_meth12 is not three (3) the value of adj_fact12 must be zero. When adj_meth12 is three (3), the PIA-fraction adjustment formula is frac[t] = adj_factor[t] * frac[t-1] for pia_frac_1 and pia_frac_2.

Valid values: 0.0 to 10.0, Real [must be zero when adj_meth12 is not three]

Source code: policy.h and policy.cpp

**SSASIM: PIADYNS . adj_meth34**

Specifies which automatic adjustment method is applied to PIA fractions 3 and 4 (pia_frac_3 and pia_frac_4) for this cal_year. A value of one (1) implies no automatic adjustment of those PIA fractions; missing cal_year values are computed by interpolation and extrapolation in the same manner as non-PIA-fraction parameters (see cal_year for details). A value of two (2) implies automatic adjustment of those PIA fractions using the "price indexing" scheme used in the CSSS plan 2. A value of three (3) implies automatic adjustment of those PIA fractions using the fixed-rate-of-adjustment scheme used in the CSSS plan 3. A value of four (4) implies those PIA fractions are equal to their values in the prior year.

Valid values: 1 to 4, Integer

Source code: policy.h and policy.cpp

**SSASIM: PIADYNS . adj_fact34**

Specifies the automatic multiplicative adjustment factor used for this cal_year when the adj_meth34 is three (3); when adj_meth34 is not three (3) the value of adj_fact34 must be zero. When adj_meth34 is three (3), the PIA-fraction adjustment formula is frac[t] = adj_factor[t] * frac[t-1] for pia_frac_3 and pia_frac_4.

Valid values: 0.0 to 10.0, Real [must be zero when adj_meth34 is not three]

Source code: policy.h and policy.cpp

**SSASIM: PIADYNS . pia_frac_1**

Specifies decimal fraction applied to AIME below first bendpoint in PIA formula. Fraction is expressed as a decimal, not in percentage terms. The prior definition is true only when adj_meth12 is one (1); otherwise, this value is interpreted as a minimum fraction, below which the automatic adjustment method cannot reduce the value of this PIA fraction.

Important note: the value of this pia_frac_1 must be equal to the values of pia_frac_1 in the PIADYNR and PIADYND tables. The values can vary by year, but they must be equal in any given year.

Valid values: 0.0 to 1.2, Real

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdiben.cpp for using the parameter in PIA computations.

**SSASIM: PIADYNS . pia_frac_2**

Specifies decimal fraction applied to AIME between first and second bendpoint in PIA formula. Fraction is expressed as a decimal, not in percentage terms. The prior definition is true only when adj_meth12 is one (1); otherwise, this value is interpreted as a minimum fraction, below which the automatic adjustment method cannot reduce the value of this PIA fraction.

Valid values: 0.0 to 1.0, Real

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdiben.cpp for using the parameter in PIA computations.

**SSASIM: PIADYNS . pia_frac_3**

Specifies decimal fraction applied to AIME between second and third bendpoint in PIA formula. Fraction is expressed as a decimal, not in percentage terms. The prior definition is true only when adj_meth34 is one (1); otherwise, this value is interpreted as a minimum fraction, below which the automatic adjustment method cannot reduce the value of this PIA fraction.

Valid values: 0.0 to 1.0, Real

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdiben.cpp for using the parameter in PIA computations.

**SSASIM: PIADYNS . pia_frac_4**

Specifies decimal fraction applied to AIME above third bendpoint in PIA formula. Fraction is expressed as a decimal, not in percentage terms. The prior definition is true only when adj_meth34 is one (1); otherwise, this value is interpreted as a minimum fraction, below which the automatic adjustment method cannot reduce the value of this PIA fraction.

Valid values: 0.0 to 1.0, Real

**SSASIM: PIADYNS . ep_app_pct**

Specifies the "applicable percentage" for OAI benefit calculation in the "enhanced PIA" formula used in two of the three CSSS reform proposals. The general PIA enhancement factor formula (see Goss-Wade 1/31/02 memo on CSSS reforms, pages 5 and 10) is as follows: PIA_enhancement_factor = 1 + ( applicable_percent * AIME_factor * coverage_factor ). NOTE: the enhanced-PIA rules are applied even when an individual with an uncovered government pension is subject to the WEP reduction in PIA; the WEP reduction is applied afterwards.

Valid values: 0.0 to 100.0, Real

**SSASIM: PIADYNS . adri_pct**

Specifies the aged-dependency-ratio indexing percent for all four SI PIA-formula AIME fractions (pia_frac_?). The aged dependency ratio is defined using the POP.maxage_yng and POP.minage_old parameters.

This adri_pct parameter is used in the following indexing factor (F) formula:

F(t) = 1 + { [R(t-2)/R(t-3)-1] * [adri_pct(t)/100] }

where R denotes the aged dependency ratio. This indexing factor is applied to each of the four SI PIA-formula fractions (Z=pia_frac_?) as follows:

Z(t) = Z(t-1) / F(t).

During the years that this indexing scheme is active (that is, years for which adri_pct is positive), the values of adj_meth12 and adj_meth34 must be either 1 or 4 and the values of pia_frac_1, pia_frac_2, pia_frac_3, and pia_frac_4 must be unchanging. These constraints ensure that no other indexing scheme is active other than the aged-dependency-ratio indexing and that no ad hoc changes to the PIA-formula fractions are being specified for those years.

Valid values: 0 to 1000, Integer
