In 2009, 30% of the bank's capital was acquired by the State General Reserve Fund of the Sultanate of Oman through its subsidiary Bulgarian Acquisition Company II Luxembourg.

[15] Tsvetan Vasilev, the State General Reserve of the Sultanate of Oman, and the depositors of Corporate Commercial Bank appealed the decision before the Supreme Administrative Court of Bulgaria.

[17] The State General Reserve of the Sultanate of Oman lodged a claim against Bulgaria for expropriation and violation of investor rights in breach of the Bulgaria-Oman Bilateral Investment Treaty.

[18] Vasilev, the management, and the depositors of Corporate Commercial Bank have lodged claims before the European Court of Human Rights.

[21] In 2017, Vasilev as well as the NGO "We, the Citizens", which represents thousands of depositors at Corporate Commercial Bank, submitted applications against media mogul Delyan Peevski and Bulgaria's General Prosecutor Sotir Tsatsarov under the US Magnitsky Act as they deem they devised a plan to artificially bankrupt Corporate Commercial Bank, so that its assets could be stolen.

[22] International depositors have submitted a claim under the US Racketeer Influenced and Corrupt Organizations Act in the United States District Court for the Southern District of New York against Delyan Peevski, the Bulgarian National Bank and others: the claimants submit the defendants engaged in fraud to deviate assets from Corporate Commercial Bank.

Corpbank customers were unable to access their money because Bulgaria violated the Directive on deposit guarantee schemes, as established by the Court of Justice of the European Union.

"[28] In addition, Bulgaria's government denied shareholders, including the State General Reserve Fund Oman, the right to bail out the bank.

[19] In March 2016, the Bulgarian government (through the Commission for Illegal Assets Forfeiture (CIAF)) filed a lawsuit against Vasilev as the main shareholder of Corpbank.

[42] The temporary committee released a report within four months after it was constituted and unequivocally put the blame for the failure of Corporate Commercial Bank on Tsvetan Vasilev.

In 2016, Desislava Atanasova argued: "The main objective of the committee was to highlight the whole process, whether this bank was operating normally or as a pyramid, which is undoubtedly proven.

"[44] "With the report of the Temporary Parliamentary Committee assigned with investigating what has happened in Corporate Commercial Bank, several myths have been broken.

[47] Yordan Tsonev, member of the temporary committee from the DPS, also argued: "MRF is motivated to reveal the whole truth about Corporate Commercial Bank.

Corporate Commercial Bank was created, operated and managed by its majority owner Tsvetan Vasilev as a financial pyramid.

[51] Meanwhile, the Organized Crime and Corruption Reporting Project reported that Bulgaria's prosecution destroyed thousands of documents related to the Corporate Commercial Bank case after investigator Boyko Atanasov gave an interview to investigative media Bivol.bg in which he claimed there was a special unit in the prosecution which was "directly subordinate" to General Prosecutor Sotir Tsatsarov, Prime Minister Boyko Borisov and Delyan Peevski and "dealt with concealing crimes and tipoffs against people close to the government, and at the same time, uses signals and tipoffs to blackmail the inconvenient.

"[52][53] In the summer of 2014, Steve Hanke, an American economist at the Johns Hopkins University in Baltimore, Maryland, was also critical of the bank's management.

[54] As subsequent reports evidencing irregularities in the approach of the government towards Corporate Commercial Bank began to emerge, he has refrained from commenting.

In December 2014, he emphasized that if the report based on which Corporate Commercial Bank's license was withdrawn was wrong even "within the range of 5%," then there were many questions "left unanswered.

The NGO's president has referred to the report prepared by the Committee headed by Desislava Atanasova, which allegedly "investigated" the case, as "tendentious and unsubstantiated.

[56][57] The president of the NGO "We, the Citizens" has also drawn attention to the various schemes employed by the government against the interests of the bank's creditors in the insolvency proceedings.

[58] In recent public opinion polls, 70% of the respondents said they believed Corporate Commercial Bank was purposefully bankrupted by the government, so that its assets could be plundered.

[59] In November 2017, the NGO sent a letter to the Bulgarian President asking him for support in their fight for justice against "the corrupt executive and judiciary, the prosecution, and dependent media.

[61] Economist Kolyo Paramov has argued that Corporate Commercial Bank is "a victim of a political plot in which Bulgarian institutions participated.

"[62] Former ambassador and current social activist Ilian Vasilev has stated that Corporate Commercial Bank is "the victim of an attack by Bulgaria's prosecution and Peevski.

Starting from scratch in 2001, it was a pioneer in export financing to Bulgarian energy producers and ammunition manufacturers previously without banking options.

Unlike its rivals, Corpbank also made direct investments in its clients and emerging enterprises in Bulgaria, most notably the country's leading telecom Vivacom, which it bought from creditors in 2012.

According to its experts, the competitiveness of Corpbank is due to a number of factors among which: understanding of the target markets and focus on export oriented companies.

The stable client base is due to the long-term relations with leading companies in the spheres of trade, energy and utility services, construction, etc.

[67] Corpbank conducts its corporate social responsibility by supporting initiatives and projects in the fields of education, healthcare, science, sports, culture, etc.

It is located in front of the Ivan Vazov National Theater and is built with funds provided by the Chairman of the Supervisory Board of Corpbank, Tsvetan Vasilev.
