Phase 1 of the project, started in March 2013, focused on the exposures of G-SIBs to their largest counterparties and to major risk dimensions. In 2015, Phase 2 will fill a substantial data gap by adding information on G-SIBs' Institution-to-Institution liabilities, their largest funding providers (banks and non-banks) and their funding structure (e.g. use of wholesale funding). The FSB also reviewed a roadmap for Phase 3, when the common template will include granular and comparable Institution-to-Aggregate (I-A) consolidated balance sheet data broken down by country, sector, instrument, currency and maturity. A Quantitative Impact Analysis will test the specification of the template and the related instructions, as well as uncover methodological issues and provide further insights into reporting challenges.
