Subsequent Events [Abstract] |
Subsequent Events | . Subsequent EventIn February 2022, we were informed that a decision was reached by the arbitration board regarding the transfer pricing matter with the CRA for tax years 2006 through 2011, as discussed in Note 11—Income Taxes above. We are awaiting further details of the results of the arbitration proceedings and the settlement provisions between the United States and Canadian competent authorities. We need to decide whether to accept the decision of the arbitration board or pursue other resolution alternatives, which is expected to occur in the first quarter of 2022.
