(1) Domain names and Other which includes patents and trademarks are deemed to have indefinite useful lives and are therefore not amortized. The Corporation's classification of certain intangible assets with indefinite useful lives is based on the expectation that these assets will continue to contribute to the Corporation's net cash inflows on an indefinite basis. The determination of these assets as having indefinite useful lives is based on judgment that includes an analysis of relevant factors, including the expected usage of the asset, anticipated renewal of the licenses, the typical life cycle of the asset and anticipated changes in the market demand for the products and services that the asset helps generate.

(2) Technology includes technological assets acquired through acquisitions and internally developed software.
