Item 2.

Identity and Background.

Subsections (a) and (c)-(f) of Item 2 of the Statement are amended by adding the following paragraph at the end thereof:

“As a result of the Ray Dolby Trust 2015 Share Transfer, as defined in Item 4, the Ray Dolby Trust is no longer a member of the Section 13(d) group and shall cease to be a Reporting Person immediately upon the filing of this Amendment.”

Item 4.

Purpose of Transaction.

Item 4 of the Statement is amended by (i) deleting the last paragraph, and (ii) adding the following paragraphs at the end thereof:

“In the third quarter of the 2015 calendar year, each of the Ray Dolby 2002 Trust A, the Ray Dolby 2002 Trust B, the Ray Dolby 2011 Trust A and the Ray Dolby 2011 Trust B adopted a Rule 10b5-1 trading plan (collectively, the “2015 Trading Plans”). The 2015 Trading Plans were established as part of each such entity’s investment strategies for asset diversification and liquidity over time. The 2015 Trading Plans were adopted during an “open window” in accordance with guidelines specified by Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, and as permitted by the Company’s insider trading policy.

A total of up to 5 million shares of the Class A Common Stock could collectively be sold under all of the 2015 Trading Plans. Each 2015 Trading Plan establishes predetermined trading parameters that, among other things, do not permit the party or parties that adopted the applicable 2015 Trading Plan to exercise subsequent influence over how, when or whether to effect trades thereunder. Pursuant to the terms of each 2015 Trading Plan, sales thereunder are based upon pre-established stock price thresholds, are subject to daily volume limits, were permitted to commence on August 10, 2015, and will continue until the earlier of August 9, 2016 or the sale of the maximum number of shares as set forth in each such 2015 Trading Plan.

On October 28, 2015, the Dagmar Dolby Trust transferred 50,450 shares of Class B Common Stock to each of the Dagmar Dolby 2014 Trust AA and the Dagmar Dolby 2014 Trust BB (such share transfers, collectively, the “2014 GRAT 2015 Annuity Share Corrections”). Each of the Dagmar Dolby 2014 Trust AA and the Dagmar Dolby 2014 Trust BB is a grantor retained annuity trust (“GRAT”) whose trust instrument requires an annual annuity payment to the Dagmar Dolby Trust, and each such share transfer was made pursuant to the terms of each GRAT’s trust instrument to correct an over payment of the first annuity payment on April 27, 2015. No reporting person paid or received any funds or other consideration in connection with the 2014 GRAT 2015 Annuity Share Corrections.

On May 21, 2015, the Dagmar Dolby Trust gifted 26,000 shares of Class A Common Stock to an unaffiliated charitable organization. On October 28, 2015, the Dagmar Dolby Trust gifted (a) 1,310,000 shares of Class A Common Stock to the Dagmar Dolby Fund, a California nonprofit public benefit corporation, and (b) 30,000 shares of Class A Common Stock to a second unaffiliated charitable organization (collectively, the “Dagmar Dolby Trust May/October 2015 Gifts”).

On October 28, 2015, the Ray Dolby Trust transferred the remaining 2,298,300 shares of Class B Common Stock to the Dagmar Dolby Trust. This transfer was made for tax and estate planning purposes (the “Ray Dolby Trust 2015 Share Transfer”).

As a result of the Ray Dolby Trust 2015 Share Transfer, the Ray Dolby Trust is no longer a member of the Section 13(d) group.

Except as described herein, none of the Reporting Persons have present plans or proposals that relate to or would result in any of the actions described in Items 4(a) through (j) of Schedule 13D.”
