The University of Notre Dame says its endowment grew by $1.5 billion during the past year. Notre Dame officials say the school's endowment reached $9.8 billion at the end of June. The university says that includes a 19.7 return on investments during the one-year period. The endowment made some $300 million in spending distributions to the university during that time. Officials say the South Bend school's endowment has nearly tripled since it was at $3.5 billion 10 years ago.
