July 2025: Download Model Comparison, Bulk Merge Expansions, and API Enhancements

This release brings powerful bulk merge capabilities, performance upgrades in debug projections, new enhancements to API functionality, and a wide set of fixes across API usage, projections, and debug tools.


New Features

Model Comparison Export

The Model Comparison Page can now be exported directly to PDF for easier sharing and documentation. After comparing your models, select a header in the left-hand navigation and click the Download PDF button.

When the top header is selected, all differences between the models will be included. You can also select a specific entity level (e.g., Company Variables) to export only the differences at that level.

Enhancements

API Reporting Endpoint

The Report API endpoint has been enhanced to support larger file sizes and to prevent request timeouts.

The previous endpoint POST /api/v1/Reports/Workbooks/{id} has been deprecated (but remains functional). It has been replaced by two new endpoints:

  • POST /api/v1/Reports/Workbooks/{workbookId}/Generate
  • GET /api/v1/Reports/Workbooks/Status/{generationId}

These new endpoints offer the following improvements:

  • Support for generating reports larger than 10MB
  • Elimination of 30-second timeout limits

The new POST endpoint supports rowLimit and offset parameters, enabling incremental progress tracking during report generation.

Implementation examples are available in our GitHub repository.

Compare & Merge Enhancements

You can now merge the following entities in bulk when comparing and merging models:

  • Currencies
  • Product Output Groupings
  • Variable Rates
  • Yield Curve Points
  • Model Point Field

Production Models

New API functionality allows you to programmatically add tables to a Production model (restricted to API only). Data tables, Decrement tables, and Scenario tables are supported.

Additional Improvements

  • Model point file validation is no longer required to be completed before running projections. If validation is incomplete, it will continue during the projection run.
  • The HPM projection log view has been expanded to show more content in a resizable window.
  • Projection progress now displays decimal values for more accurate tracking of long-running jobs.
  • The GetDownloadUrl API endpoint now accepts an optional Content-MD5 parameter for file integrity verification.
  • HPM Debug Mode has been further optimized for faster execution.
  • Support has been added for merging decrement table deletions across models.
  • Duplicating a projection template now pre-fills the template description for faster setup.
  • Variable tags in the sidebar are now automatically sorted in alphabetical order.
  • You can now see the associated investment strategy version directly in the projection template view.

Fixes

  • 2D portfolio variables now display expected results in the debug view after successful calculations.
  • Resolved timeout errors (502/504) caused by performance issues during Model Point File validation.
  • File-only data tables now raise appropriate errors when containing duplicate indexes referenced by variables.
  • Text selection now works correctly when double-clicking inside the variable filter.
  • Renaming table structure columns after a projection has been run now works without errors.
  • Invalid Data Type errors in File-only data tables are now being shown.

Life Library Update 2025.05: Beta release of Variable Annuity, Combined Fixed/Indexed Annuity products

This release introduces beta versions of two new products: a Variable Annuity product (includes RILA support) and a combined Fixed/Indexed Annuity product. Additionally, updates include updated Life & Annuity US Stat/Tax Interest Rates, clean up and fixes to asset product calculations, and more.

Variable Annuity product beta release

A new product within the Life Library has been released under beta status which covers Variable Annuities and Registered Indexed Linked Annuities (RILAs). This product offers the following:

  • Tracking of multiple investment accounts and tracking of individual deposits within each investment account
  • Support for GMAB, GMDB and GMWB/GLWB riders
  • Deposit level cashflows and guarantees
  • Fixed account components
  • Deposit specific assumptions and parameters (e.g. partial withdrawal rates, market value adjustments, and surrender charges)
  • Tracking of potential GMWB election dates through the projection, including the use of different lapse rate assumptions for each potential election path

Note that the beta status means features have not yet been fully tested and the models may produce erroneous results in some instances. If you find any issues, please report them to us at support@slopesoftware.com

Combined Fixed/Indexed Annuity product beta release

A new product within the Life Library has been released under beta status which covers a combined product for all Fixed and Indexed annuities. This product is intended to replace the Fixed Annuity and Indexed Annuity products currently in our library. The two legacy products will be sunset sometime (timeframe TBD) after the combined Fixed/Indexed Annuity product is moved out of beta status.

This combined Fixed/Indexed Annuity products offers many new features, including:

  • Easier management of policies with both fixed and indexed components
  • Support for GMAB, GMDB and GMWB/GLWB riders
  • Deposit level tracking of cashflows and guarantees
  • Deposit specific assumptions and parameters (e.g. partial withdrawal rates, market value adjustments, and surrender charges)
  • Tracking of potential GMWB election dates through the projection, including the use of different lapse rate assumptions for each potential election path

Like with the Variable Annuity product, this product is in beta status. If you find any issues, please report them to us at support@slopesoftware.com.

New Workbook

A new workbook has been created to analyze results from the Fixed/Indexed Annuity product. It covers the following:

  • Single policy projected cash flows and policy counts
  • Projected account value rollforward
  • Projected account value for each investment account and deposit
  • GMWB details including projected GMWB elections and details for each projected election date
  • US STAT CARVM reserve details for AG33 and AG35, including inner loop calculations for each timestep of the projection
  • US GAAP ASC 815 (formerly FAS 133) details

Asset Clean Up

Fixes

  • Updated Realized Book Value used in the Realized Gain/Loss for Non-Callable bonds to default to Book Value instead of US STAT reported value to resolve errors that occur when US STAT results are not calculated.
  • Resolved inconsistencies with Default Rate Annual and Default Rate Monthly formulas across asset products by setting their properties to:
    • Output = True
    • Always Calculate = False
  • Fixed Initial Asset Scaling variables in 4 asset products (Asset Backed Security, Collateralized Loan Obligation, Mortgage Backed Security, Stock Option):
    • Set the variable to equal 1 (i.e. do not scale) for reinvestment assets
    • Set Model Point Aggregation Method to None (from First Value) to prevent unnecessary aggregation of this variable
  • Corrected the Default Rate Monthly in the Collateralized Loan Obligation product to properly reflect a conversion from an annual to monthly default rate
  • Removed outdated and irrelevant references in the documentation for Default Rate Annual and Monthly variables that have not applied for quite some time.

Changes

  • Replaced references in the asset products to the product instance name system variable with a new Product Definition Name variable to resolve errors that occur when the product instance name is modified on a projection. This new variable references a new Asset Product Definition Names array whose values correspond to product definition names in the Slope Life Library. 
  • Updated Initial Asset Scaling formulas to reference new Asset Product Definition Names array and to be consistent across all asset products
  • Added more flexibility to management of Default Rate assumptions such that you can now specify separate default tables for each asset product rather than use a single table with an asset product index column. Changes related to this include:
    • Added records in the Standard Assumptions table of the Asset Assumptions table structure to split out each assumption by the Asset Product Name index column rather than use a default across all products.
    • Added a Default Rates Table data table column in the same table as the previous bullet and assigned tables corresponding to the library assumption for each asset type (default rate assumption remains unchanged from before)
    • Default rate product variables in each asset now reference this nested table structure via a new Default Rate Table data table variable 

Other Changes

Fixes

  • Fixed the Indexed Annuity option cost calculations in both the combined Fixed/Indexed Annuity product and the legacy Indexed Annuity product. The fix moves the participation rate outside of the brackets to apply to both the base and cap option costs and not just to the base option. Three variables are affected in each product, found by searching for “option cost”.

Changes

  • Added Life & Annuity US Stat and Tax Interest Rates for 2024 (Life, Annuities, SPIA) and for 2025 (Life) in table structures
    • US STAT Valuation Rates – Life
    • US STAT Valuation Rates – Annuity
    • US STAT Valuation Rates – SPIA
  • Renamed the array options in Indexed Annuity US STAT Valuation Method from AG33 to AG33/AG35 with the release of the combined Fixed/Indexed Annuity product. In that product, one of AG33 (for Fixed) or AG35 (for Indexed) is applied based on the investment account type being valued. In the future, this array name will be renamed to Fixed/Indexed Annuity US STAT Valuation Method for clarity.

Coming Soon

  • Projection result comparison workbook
  • Other asset-related updates
  • Pension Risk Transfer library model

Pension (Governmental) Library Update 2025.03.01: Fixes

Fixes

  • Fixed an issue in the calculation of Product variable “Entry Age 02 – State – Head Count BOP (Actives)” affecting plans using the Misc 2 decrement where the Misc 2 decrement rate should have been subtracted rather than added
  • Fixed an issue where a $0 retiree benefit amount causes Retiree Payment Form Factors to divide by zero. See product variable “In Pay Record 26 – Payment Factor Annuity”.
  • Fixed an issue where providing no Social Security benefit table in table structure “Benefit Formula Table References Not Yet in Pay” causes product variable “Product Variable “Social Security 04.4 Age to start compensation history” to default to 0. The variable now defaults to the value of product variable “Age at Valuation Date” instead of 0

Version 2025.03 of the Slope Governmental Pension Library has been unpublished so our users do not mistakenly utilize these invalid setups. If you require a copy of this version prior to the fixes, please contact support@slopesoftware.com.

June 2025: Dynamic Model Point Variables in High Performance Mode, Compare & Merge Enhancements for Tables, Updated Workbook Editing Layout

New Features

Dynamic Model Point Variables in High Performance Mode

High Performance Mode now supports models with dynamic model point variables. This allows product variables to reference Portfolio or Company variables from prior time periods. See the diagram below and the Dynamic Projection Processing section of this support article for more details.

References to the summarized results of Products within Portfolio and Company variables continue to be supported, as these will have already been calculated.

Coming soon: Support for projections with initial asset scaling and investment in High Performance Mode (HPM).

Enhancements

Table Structure Column Sort Order Now Visible in Governance

When comparing models, users can now clearly see differences in a Table Structure’s column sort order, enabling more reliable and predictable model adjustments.
Note: Sort order changes are not mergeable at this time.

Data Table Column Differences Now Visible in Governance

When comparing models, the following Data Table column differences are now displayed.
Note: These differences are not mergeable at this time.

  • Index Column: Yes/No
  • Index Read Method: Exact Match or Range Lower Bound
  • Sort Order
  • Data Type
  • Dropdown List Array (if applicable)
  • Table Structure Name (if applicable)

New Workbook Editing View

Workbook editing has a new look! Properties, formatting options, and actions are now neatly organized into tabs, so you can make quick adjustments without feeling lost.

A new element bar allows for inserting charts, tables, and other elements on the fly.

Fixes

  • Resolved an intermittent issue where the filter values for some workbook controls were not being populated
  • Added stability around hardware failures to prevent intermittent, inaccurate Product Aggregates on certain larger HPM projections
  • Fixed an issue where adding a model point file to a product using the API would sometimes fail.
  • Saving allocations on models no longer causes intermittent errors.
  • Computations in the profiling workbook are now correctly attributed to their respective variables.
  • Adding a column to a table structure after deleting an array that was used for a dropdown list no longer results in an error
