Consensus agreement from the authority is needed for all decisions, and it has become a model for regional cooperation in Southeast Michigan. In October 2010, the DRCFA awarded a management contract to SMG. It extended the contract for three years in September 2013 and again in June 2017. In 2015, a five-year, $279 million renovation was completed, including a new atrium, ballroom, and meeting spaces, constructed mainly within the former Cobo Arena building. In 2017, in the wake of the 50th anniversary of the 1967 Detroit riot, current mayor Mike Duggan proposed that Cobo Center be renamed due to modern reappraisals of Cobo's tenure as mayor. Cobo had upheld exclusionary covenants against African Americans, and was accused of responding poorly to allegations of harassment and police brutality against African American residents. In 2018, the DRCFA stated that it had already been considering the sale of naming rights to the facility, for the first time in its history. In June 2018, the DRCFA approved a 22-year naming rights agreement with Chemical Bank which took effect on July 1, 2018 (the following month, the bank announced that it would relocate its headquarters to downtown Detroit). The deal would not be publicly announced until February 20, 2019; the parties agreed to delay the official announcement until Chemical finalized and announced its agreement to merge with the Minnesota-based TCF Financial Corporation. A new name for Cobo Center was not formally announced at this time, as the bank wanted to wait until after the completion of the merger. In the meantime, the Chemical Bank branding would appear on advertising and signage at the facility, and a ceremonial bust of Albert Cobo was removed from public display. The Chemical–TCF merger was completed on August 1, 2019, and the combined company took on the TCF name. Cobo Center was officially renamed TCF Center on August 27, 2019. Since 1965, the largest event held at TCF Center is the North American International Auto Show (NAIAS). This event draws thousands of international press and suppliers during its initial five days and has a charity preview party for 11,000 guests before the public opening. Since 1976, the Charity Preview has raised an average of $2.4 million yearly for southeastern Michigan children's charities. After the Charity Preview party, the NAIAS is open to the public for ten days, drawing, on average, 735,000 attendees. The show was originally held in January, but was to move to June beginning in 2020. On March 29, 2020, it was announced that the 2020 NAIAS had been cancelled due to the COVID-19 pandemic and the conversion of TCF Center to a field hospital by FEMA workers.
