Effective February 16, 2018, the Board of BlackRock Income Trust, Inc. appointed Robert Fairbairn as a Class III Board Member to fill the vacancy created by the resignation of a Class III Board Member. The Board has determined that it is desirable for Mr. Fairbairn to stand for election this year to serve out the term of the vacancy to which he was appointed. If Mr. Fairbairn is elected at the meeting, he will serve as a Class III Board Member until the later date of the 2019 annual meeting (when all of the Class III Board Members stand for election) or until his successor is elected and qualifies, or until his death, resignation, retirement or removal.
