[2] As of the fiscal year ending June 30, 2015, BWC provides workers' compensation insurance coverage to approximately 253,000 public and private sector employers in the State of Ohio.

[5] In 2005, the OBWC became involved in a massive investment scandal that ultimately contributed to the defeat of the Republican Party leadership of the state government in Ohio.

Thomas Noe, a Republican Party fundraiser and activist was charged with running a criminal enterprise, the theft of $13 million from the fund, and of keeping a second set of books to cover for it.

[citation needed] However, as part of that sale process, OBWC engaged Ennis Knupp to conduct a thorough valuation of its alternative investment holdings.

The Columbus Dispatch subsequently made a request under the Freedom of Information Act to receive the Ennis Knupp valuation report, which included confidential materials that the various private equity firms objected to OBWC disclosing.

[8][9] In the years following the Coingate scandal, BWC has replaced its senior management and investment teams and has been scrutinized heavily by the new Democratic administration in Ohio.

The case was referred to prosecutors for possible charges involving theft of state time and the inspector general urged the BWC to monitor more closely its employees' computer use.

The report follows a decision from Judge Richard McMonagle of the Cuyahoga County Court of Common Pleas that the Ohio BWC violated two state statutes by charging the class excessive premiums.

"[14] On March 20, 2013, Cuyahoga County Common Pleas Judge Richard McMonagle ordered the Ohio Bureau of Workers Compensation to refund $860 million in illegal over-charges to some 270,000 employers.
