We hold strategic investments primarily in privately held companies, consisting primarily of equity securities without readily determinable fair values, and to a lesser extent, debt securities. These strategic investments are primarily recorded at fair value on a non-recurring basis. The estimation of fair value for these privately held strategic investments requires the use of significant unobservable inputs, such as the issuance of new equity by the company, and as a result, we deem these assets as Level 3 financial instruments within the fair value measurement framework.
