An Unusual Tax Situation

We can see that Air Canada received a tax benefit of CA$1.3b. It's always a bit noteworthy when a company is paid by the tax man, rather than paying the tax man. The receipt of a tax benefit is obviously a good thing, on its own. However, the devil in the detail is that these kind of benefits only impact in the year they are booked, and are often one-off in nature. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal.

That might leave you wondering what analysts are forecasting in terms of future profitability. Luckily, you can click here to see an interactive graph depicting future profitability, based on their estimates.

Our Take On Air Canada's Profit Performance

In its most recent report, Air Canada disclosed a tax benefit, as we discussed above. Given that sort of benefit is not recurring, it's safe to say the statutory profit overstates its underlying profitability quite significantly.

At the end of the day, it's essential to consider more than just the factors above, if you want to understand the company properly. In light of this, if you'd like to do more analysis on the company, it's vital to be informed of the risks involved.
