Overview
Aareal Beteiligungen AG is a German holding company based in Frankfurt am Main and a wholly owned subsidiary of Aareal Bank AG. It has no operating business today, but it is the legal successor to a long line of German mortgage banks. Its most recent operating identity was Corealcredit Bank AG, which was acquired by Aareal Bank in 2014 and renamed Aareal Beteiligungen. Before 2007 the same institution traded as Allgemeine Hypothekenbank Rheinboden AG (AHBR), a name created by the 2001 merger of Allgemeine Hypothekenbank AG (AHB) and Rheinboden Hypothekenbank AG. The older of those two roots, Rheinboden, was founded in Cologne in January 1894 as the Rheinisch-Westfälische Boden-Credit-Bank by a 29-member banking consortium in which A. Schaaffhausen'scher Bankverein played a leading role. For much of the twentieth century Rheinboden was associated with the Cologne private bank Sal. Oppenheim, while AHB, founded in 1962, passed through the orbit of the trade-union-linked Bank für Gemeinwirtschaft and later the BHW group. After the 2001 merger the combined bank, AHBR, ran into the German real estate crisis of 2001/02, suffered derivatives losses and refinancing pressure, and required repeated recapitalisations. In late 2004 the German regulator BaFin classified AHBR as systemically important and demanded further capital; in 2005 a €2.5 billion liquidity shield from five leading German private banks stabilised the Pfandbrief market, and the US investor Lone Star took a majority stake in December 2005. The bank was renamed Corealcredit Bank in 2007 after a strategic realignment, and Aareal Bank acquired it in 2014. Since then the entity has existed as Aareal Beteiligungen AG, a non-operating holding company within the Aareal Bank Group. Aareal Bank itself is a listed German commercial real estate lender headquartered in Wiesbaden, focused on commercial property financing for international investors and on corporate banking for the housing and energy industries.
History
The institution now known as Aareal Beteiligungen AG traces its origins to two German mortgage banks. The older, Rheinboden Hypothekenbank AG, was founded in Cologne in January 1894 as the Rheinisch-Westfälische Boden-Credit-Bank by a 29-member banking consortium; the A. Schaaffhausen'scher Bankverein was a leading participant. It began business the same year and was organised as an Aktiengesellschaft even though the legal-form suffix did not appear in its original name. The short form "Rheinboden" followed the naming convention of other German mortgage banks such as Südboden, Westboden and Centralboden. In 1989 the shareholders resolved to rename the bank Rheinboden Hypothekenbank AG, effective the following year. For decades the bank was within the sphere of influence of the Cologne private bank Sal. Oppenheim, which held shares directly and through other holdings; a group relationship was established in 1971, and from 1992 Sal. Oppenheim itself held the majority. The second root, Allgemeine Hypothekenbank AG (AHB), was founded on 8 March 1962 in Cologne with capital of DM 8 million. Its major shareholders at foundation were the trade-union-owned Bank für Gemeinwirtschaft (BfG) and Allgemeine Finanzberatung Allfina of Cologne. In 1964 the head office moved to Frankfurt am Main, with Cologne becoming a branch, and in 1971 the bank moved into its first own bank building. In 1987 and 1988 the then-major shareholders BfG and Volksfürsorge sold their stakes to the Beteiligungsgesellschaft für Gemeinwirtschaft (BGAG), later renamed Beteiligungsgesellschaft der Gewerkschaften AG. On 1 April 1996 the BHW group took over entrepreneurial leadership of AHB through a voting-pool agreement with BGAG. In the late 1990s AHB became a prominent address in the Jumbo Pfandbrief market, issuing public Pfandbriefe to refinance public-sector financing. In January 1999 it was the first German mortgage bank to issue a euro-denominated Jumbo Pfandbrief; in August 1999 it issued a €5 billion euro Jumbo Pfandbrief; and in April 2000 it issued the first e-Pfandbrief, which could be subscribed via special internet platforms. In 1999 and 2000 AHB also built up its international real estate lending business and opened offices in London, Paris, Madrid and Amsterdam, with New York and Milan following later under the AHBR name. In 1999 AHB acquired 25.1% of Rheinboden's share capital, and by May 2000 it held 87.3%. On 1 July 2001 Rheinboden was merged into AHB, and the combined bank traded as Allgemeine Hypothekenbank Rheinboden AG (AHBR), remaining within the BHW group. It positioned itself as a classic mortgage bank active in public-sector financing and in commercial (national and international) and private real estate financing. However, AHBR ran into difficulty in 2001/02 with the onset of the German real estate crisis, burdens from its derivatives portfolio and higher refinancing costs. Despite repeated recapitalisations by BGAG and BHW it could not recover on its own. When further losses loomed at the end of 2004, BaFin classified AHBR as systemically important and urgently demanded another recapitalisation; BGAG then began a sales process for BHW and AHBR in early 2005. On 25 October 2005 it became public that BHW, which had exercised entrepreneurial leadership over AHBR, would be sold to Deutsche Postbank AG separately from AHBR's risks. The crisis intensified when the Pfandbrief market showed signs of alarm and some securities could no longer be traded. To ensure the liquidity of the Pfandbrief market, AHBR had to be supported under BaFin guidance by a €2.5 billion liquidity shield provided at short notice in equal parts by the five leading German private banks. In December 2005 LSF5 German Investment L.P., an investment fund of the American financial investor Lone Star, took over the majority of AHBR shares, with the buyer largely released from past losses; in January 2006 Lone Star's stake rose to 87.9%. After a fundamental strategic realignment the bank was renamed Corealcredit Bank in 2007. In 2014 Aareal Bank acquired Corealcredit Bank. The entity was subsequently renamed Aareal Beteiligungen AG, based in Frankfurt am Main, and today has no operating business, existing as a wholly owned subsidiary within the Aareal Bank Group. Aareal Bank AG itself is headquartered in Wiesbaden and describes itself as a leading real estate specialist with global reach and local expertise, operating through two strong segments: commercial real estate financing for international investors and corporate banking for the housing and energy industries.
