Securities accounting that integrates closing and tax logic.
TTL Depot translates portfolio and transaction data into traceable accounting, valuation, and tax results for securities in business assets. From data import to closing — rule-based, reviewable, and auditable.
Bank data shows movements. Not the full logic of business assets.
Securities portfolios in business assets require more than recording purchases, sales, dividends, and interest. For accounting and closing, holdings, acquisition costs, partial disposals, fees, corporate actions, withholding taxes, fund-tax logic, balance-sheet assignment, and period-end valuations must be processed consistently.
In practice, different bank keys, file formats, and document data meet client-specific valuation and booking rules. The result: manual bookings, spreadsheet workarounds, recurring follow-ups, and a history that can only be reconstructed with considerable effort.
TTL Depot maps this process as an end-to-end specialist and data logic.
From portfolio movements to documented accounting and tax results.
TTL Depot consistently separates three layers — so that tax specifics never stay hidden in booking entries, and economic events are never interpreted for tax too early.
Purchase, sale, distribution, redemption, or corporate action.
Addition, disposal, income, expense, reclassification, impairment, or write-up.
Participation gains/losses, Vorabpauschale, partial exemptions, tax valuation adjustments, withholding-tax status, and further on- and off-balance-sheet corrections.
Eight modules. One closing process.
Imports defined bank, broker, and portfolio data, stores the original source, and normalises keys, dates, amounts, and instrument references into a canonical event model.
Known source keys and event patterns are classified by rules. Unclear descriptions can be interpreted technically; final processing stays bound to rules and approvals.
Holdings, additions, partial disposals, and acquisition costs are maintained per portfolio, instrument, tax profile, and balance-sheet assignment.
Corporate actions are broken into structured sub-steps: quantity change, instrument exchange, book-value split, cash component, subscription right, or option.
Market prices, exchange rates, balance-sheet assignment, and valuation rules come together at the reporting date. Accounting valuation and tax deviation are stored separately.
Tax profiles, asset class, fund type, participation information, jurisdiction, and period drive the rule packs. Result: structured tax components and adjustment items.
Semantic booking entries first; a mapping layer translates them into the client-specific chart of accounts or target system.
Holdings, liquidity, tax components, corporate actions, and closing values are reconciled against external sources. Deviations receive category, cause, status, and history.
A structured closing process instead of isolated one-off bookings.
Documents you can hand to the auditor.
Not just booking. A complete processing logic.
Rules first.AI afterwards.
Known events and specialist rules are processed deterministically. Technologies for document interpretation or pattern recognition serve as support. They supply structured candidates, evidence, and confidence — but no unchecked final booking or tax decision.
Concrete specialist questions.
The recommended core scope includes equities, bonds, retail funds/ETFs, standardised derivatives, and defined corporate actions. The specific product scope must be confirmed per data source, rule pack, and project phase.
Yes, balance-sheet assignment is designed as an attribute at mandate or position level. It must not be derived from ISIN or asset class alone and in particular drives valuation logic.
Corporate actions are broken into structured sub-events, e.g. derecognition of the old holding, recognition of the new instrument, book-value split, and recording of the cash component. Special cases may require a specialist review.
No. TTL is a specialised subledger for securities data. The platform delivers structured booking and reporting results for downstream accounting and tax systems.
Corrections are traceable via reversal and rebooking or versioned adjustments. Original event, rule version, and approval are retained.
Yes, in a limited and controlled way, for example for reading documents or unknown bank descriptions. Final specialist processing stays rule-based and reviewable.
