We have had the benefit of using this tool over the summer. I would say that there are two parts to the calculation. There's the math and the accuracy.
On the math, we ran 2,000 transactions that went through legacy systems and through CARM 2.0. Of the 2,000 transactions or submissions that we ran through, only two had a discrepancy. In terms of a mathematical calculation, they're identical.
In terms of interpretation of the Excise Tax Act and the Customs Act, we're finding significant discrepancies. Our estimates show that in the range of $200 million in discrepancies will be identified by CARM each year. We have a detailed list of recurring errors that are being made. We've already launched dozens of compliance campaigns through which we're contacting businesses and alerting them to these interpretive errors.
I would say that the concerns around calculations fall into two camps—the legislative interpretation of the correct coding and treatment of the acts, and the math. Our experience over the summer shows that the math is identical between CARM 2.0 and legacy, but CARM does have better analytics to flag compliance issues.
