ATTLAS®
ATTLAS® — Global Tax Lot and Cost-Basis Intelligence
ClearOne’s Active Trader Tax Lot Accounting System, ATTLAS, has evolved into the global standard for institutional tax-lot and cost-basis reporting.
Tax reporting is a universal requirement that drives financial transparency and trust. ATTLAS turns that obligation into an advantage by giving financial institutions real-time, continuous visibility into cost basis, income, and tax positions across every market.
It processes and reconciles data for securities, derivatives, and digital assets within a single, unified global platform. Firms gain immediate insight into exposures, realized gains, and funding impacts across custodians, entities, and jurisdictions.
ATTLAS is built for the era of real-time finance, where compliance and accuracy move together.
Unified Tax Lot Accounting
ATTLAS consolidates positions, transactions, and cost-basis data across multiple entities, accounts, and custodians into a single synchronized framework. It reconciles internal books, external records, and regulatory filings in real time, ensuring that every lot, gain, and adjustment is consistent across systems. This unified structure eliminates manual reconciliation, speeds reporting, and maintains a continuous, regulator-ready level of accuracy.
Regulatory Compliance and Audit Readiness
ATTLAS maintains constant alignment with global cost-basis and tax-lot standards, including those of the IRS, SEC, ESMA, HMRC, MAS, HKMA, and other jurisdictional frameworks. In every market, the firm bears the reporting burden, and errors cost penalties and credibility. ATTLAS reduces that risk through automated accuracy, full lineage, and ongoing audit readiness across all regulatory bodies—making compliance a built-in outcome.
Corporate Actions Automation
ATTLAS automates the tax and accounting effects of mergers, acquisitions, stock splits, and reorganizations. It recalculates cost basis, maintains historical continuity, and applies regulatory rules in real time so every derived position remains accurate and traceable. Firms achieve seamless reporting and complete transparency through complex event chains.
Profit and Loss Optimization
ATTLAS supports configurable tax-lot selection strategies including FIFO, LIFO, Specific Identification, Average Cost, and optimized gain/loss realization. Integrated with margin and treasury systems, it aligns capital efficiency with tax outcomes across asset classes and entities—turning selection from a compliance task into a strategic advantage.
Comprehensive Reporting
ATTLAS produces trade-level, lot-level, and consolidated statements across all regions and currencies. It records pricing exceptions, cancellations, dividend adjustments, and corporate-action effects automatically, generating compliant 1099, 1042-S, FATCA, CRS, and AEOI filings, plus jurisdiction-specific reports aligned with HMRC, ESMA, MAS, IRAS, and ASEAN regulations. Real-time dashboards and standardized templates deliver verified, export-ready data on demand.
Global Differentiation
Unlike regional cost-basis systems designed for single-market compliance, ATTLAS functions as a unified global tax infrastructure. It calculates, reconciles, and reports across jurisdictions, asset classes, and regulatory regimes in real time—providing a consistent, transparent view of tax, income, and gain/loss reporting for traditional, cross-listed, and tokenized assets.
High-Volume Processing Engine
Built for multi-asset, multi-entity environments, it handles millions of transactions daily with verified reconciliation accuracy above 99.99 percent.
Advanced Tax Lot Management
Tracks open and closed positions across equities, fixed income, derivatives, mutual funds, ETFs, REITs, partnerships, and tokenized assets with detailed lot-level lineage.
Automated Cost-Basis Calculation
Automatically applies IRS and international rules; adjusts for wash sales, transfers, substitutions; recalculates historical basis for corporate actions or retroactive filings.
Income and Cash Flow Analytics
Generates position- and lot-level income statements for monthly, quarterly, and yearly reporting, including MTD, QTD, YTD, and estimated annual income.
Cross-System Integration
Connects to books-and-records, OMS, and clearing systems via ISO 20022, FIX, and SFTP. Integrates with digital asset custody and DeFi tax reporting through ClearOS APIs.
Enhanced Data Exchange
Imports and exports tax lots via DTCC’s Cost Basis Reporting System (CBRS) and global counterparts—ensuring full transparency among custodians, brokers, and intermediaries.
Custom Reporting and Analytics
Supports ad-hoc queries, user-defined fields, and custom extracts. Exports directly to Excel, CSV, and major tax software.
Corporate Action Traceability
Links each post-event position to its original transaction and cost basis, allowing regulators and auditors to trace every adjustment end-to-end.
