Our Treasury function manages our capital at Group level and locally in each region. The allocation of financial resources, in general, and capital, in particular, favors business portfolios with the highest positive impact on our profitability and shareholder value. As a result, Treasury periodically reallocates capital among business portfolios.
Treasury implements our capital strategy, which itself is developed by the Capital and Risk Committee and approved by the Management Board, including the issuance and repurchase of shares. We are committed to maintain our sound capitalization. Overall capital demand and supply are constantly monitored and adjusted, if necessary, to meet the need for capital from various perspectives. These include book equity based on IFRS accounting standards, regulatory capital and economic capital as well as specific capital requirements of rating agencies.
Regional capital plans covering the capital needs of our branches and subsidiaries are prepared on an annual basis and presented to the Group Investment Committee. Most of our subsidiaries are subject to legal and regulatory capital requirements. Local Asset and Liability Committees attend to those needs under the stewardship of regional Treasury teams. Local Asset and Liability Committees further safeguard compliance with requirements such as restrictions on dividends allowable for remittance to Deutsche Bank AG or on the ability of our subsidiaries to make loans or advances to the parent bank. In developing, implementing and testing our capital and liquidity, we take such legal and regulatory requirements into account.
