Oct 13 (Reuters) - BlackRock Inc, the world’s largest money manager, reported a 19% rise in third-quarter profit on Wednesday as an improving economy helped boost its assets under management, driving up fee income. Adjusted net income rose to $1.69 billion, or $10.95 per share, in the quarter ended Sept. 30, from $1.42 billion, or $9.22 per share, a year earlier. Analysts on average were expecting the company to report a profit of $9.35 per share, according to IBES data from Refinitiv.
