PORTLAND — A government audit in Canada found Nova Star Cruises spent $40.7 million (Canadian) in its first sailing season between Maine and Nova Scotia in 2014, but the company’s revenues were not revealed.

The spending figures include about $26 million in subsidies from the Nova Scotia government, meaning about 63 percent of the service’s first year was paid for by $21 million in initial subsidies and another $5 million the province gave Nova Star Cruises to close out the season.

The Halifax-based auditing firm KPMG said the purpose of the audit was to confirm that the ferry service used the subsidies for the intended purposes of starting up and operating the daily route between Portland and Yarmouth, Nova Scotia.

Of 1,037 transactions, worth $25.4 million, reviewed by auditors, there were 35 transactions worth $79,265 for which the company was not able to provide supporting documentation.

Nova Scotia Economic Development Minister Michel Samson said during a news conference Thursday about the audit that the results are not a cause for concern, according to the Yarmouth County Vanguard.

The initial subsidy was intended to last seven years and its full expenditure in Year One leaves the parties without a contract.

The company announced Thursday that the vessel had left a dock in Shelburne, Nova Scotia, to travel to less expensive lodgings in Charleston, South Carolina, for the rest of the winter. The ferry’s operators are still pursuing a winter route that could generate off-season revenue for the company.

Nova Scotia officials have said that if the seasonal service between Portland and Nova Scotia continues it would be with Nova Star Cruises and not any other operator.

In releasing the audit numbers, the province attempted to redact the exact line-item costs, but the PDF files it uploaded to its website contained text confirming the company spent $10.5 million in startup costs and $30.2 million on operating costs.

The company previously stated it would use $10.5 million in provincial subsidy for startup costs, and the operating cost totals could also be ascertained from unredacted audit numbers.

Various newspapers in Canada reported government officials said they redacted the line-item totals from the documents to prevent that cost information from becoming available to potential competitors.

A review by the Bangor Daily News found the company paid about $6.3 million for the 528-foot ship, making up the bulk of its startup costs. It spent another 25.6 percent of startup costs on overhead.

Its operating costs were mostly for engine and deck costs, with about 13 percent of operating costs spent on a sales and reservation system.

A spokesman for the company in Maine was not immediately available for comment Friday afternoon.
