      <Desc>Orchestra Music Programs: The BSO's two beloved orchestral ensembles-the Boston Symphony and Boston Pops-offered 405 concerts reaching more than 1.141 million audience members. Internationally recognized as one of the finest orchestras, the BSO is one of the largest orchestral organizations in the world as measured by scope of its operations. Within the U.S., it is the fourth-largest performing arts institution. In 2018-2019, the BSO welcomed 213,790 patrons to Symphony Hall for its winter season, 202,270 for its Holiday and Spring Pops seasons, 194,860 attended a concert at Tanglewood in Lenox, MA. 28,010 attended Youth and Family Concerts and High School Open Rehearsals and 502,150 enjoyed community concerts offered across the Greater Boston region, including the Boston Pops July 4th concert on the Charles River Esplanade. Highlights included: the opening of the new Linde Center for Music and Learning on the grounds of Tanglewood, which houses the Tanglewood Learning Institute and its year-round roster of innovative programming and performance and rehearsal spaces for the Tanglewood Music Center. The Boston Symphony Children's Choir became the newest permanent ensemble within the symphony, enriching and expanding the BSO's repertoire while giving children an extraordinary choral education. The Boston Pops performed its first ever sensory friendly concert designed for families with a child or adult who is impacted by the autism spectrum disorder.</Desc>

        <Desc>Education and Community Programs: Education and community programs are integral to the BSO's mission and are delivered via: 1) The Tanglewood Music Center (TMC), BSO's summer academy for rising professional musicians; and 2) Education and Community Engagement Department programs. The TMC is a bridge from the conservatory to the professional world. Promising young musicians study with some of the world's finest practitioners as they prepare for successful performing careers. In 2019, the TMC provided 141 of the world's most promising young musicians-from 24 states and 12 countries-the opportunity to engage in intensive, performance-oriented work with BSO musicians, resident and guest faculty members, and guest artists. The TMC Fellows studied orchestral and chamber music, with an emphasis on contemporary music, vocal repertoire from art song to opera, composition, and conducting. They presented 26 orchestral, vocal, and chamber concerts throughout the summer, including the week-long Festival of Contemporary Music enjoyed by 11,710 audience members. The TMC also functions as a think tank for faculty, who have the time and talent to explore uncharted directions in composition, conducting, and collaboration to advance and influence the field. Education and community engagement programs reached more than 31,000 students, teachers, and families, many of whom came from low-income households in and around Boston. Highlights included: 1) 16 Youth and Family Concerts and High School Open Rehearsals where 23,775 tickets were distributed and children under age 18 attended Family Concerts for free. 1,534 students from 27 Boston Public Schools received free tickets to Youth Concerts. 2) Approximately 2,150 people attended a Community Chamber Concert, where BSO musicians performed in small ensembles around the region including Framingham, Roxbury, Worcester, and Watertown. 3) Symphony for Our City is a partnership between the BSO and 11 Greater Boston nonprofit organizations serving diverse populations. 372 clients of the nonprofits attended BSO, Pops, and Tanglewood performances. 4) Days in the Arts (DARTS): 368 students participated in a week-long residential summer arts immersion program. Thanks to the BSO's generous tuition subsidies, students from urban, suburban, and rural communities gained confidence as they explored different art forms as creators and audience members.</Desc>

        <Desc>Historic Preservation and Conservation and Facility Rental: The BSO's two main properties, Symphony Hall and Tanglewood, have long and significant histories and both attract visitors from near and far. Symphony Hall's acoustic qualities have earned it a place among the top three concert auditoriums in the world, a fact underscored by the hall's 1999 designation as a National Historic Landmark. Symphony Hall resonates with more than a century of performances by key artists. It is also a key performance venue for a number of ensembles and presenters, including the Handel and Haydn Society, the Celebrity Series of Boston, and the Boston Youth Symphony Orchestra. The hall has a 2625 seat capacity. Located in the Berkshire hills of Lenox, Massachusetts and established in 1936 by then-Music Director Serge Koussevitzky, Tanglewood is the summer home of the BSO. Its performance venues-Koussevitzky Music Shed, Seiji Ozawa Concert Hall, and Linde Center-and 80 ancillary buildings are located on 526 pastoral acres in the Berkshire hills in western Massachusetts. The grounds are open to the public year-round. Tanglewood attracts more than 200,000 visitors annually and presents ten weeks of diverse programming, including BSO, Pops, and Tanglewood Music Center concerts. Built in 1938, the Koussevitzky Music Shed is a seasonal hall open on three sides with 5,121 seats and additional seating for more than 10,000 on the surrounding lawn. BSO concerts are performed in the shed. Opened in 1994, Seiji Ozawa Hall is a brick and wood structure that provides a venue for chamber music performances and serves as the headquarters of the Tanglewood Music Center. It seats 750 audience members on the orchestra level and an additional 450 in the two balconies, as well as hundreds more on the lawn. This year, the BSO completed a $70 million Tanglewood Forever campaign, which included $43 million for facilities and landscape improvements; $23 million in endowment funds to support Tanglewood programs; and $4 million for existing and new learning and community programs.</Desc>

        <Desc>Electronic Media: In addition to creating music for live audiences, the BSO reaches millions who listen via record, radio broadcast, and digital media. Local broadcasts of BSO concerts can be heard on 99.5 Classical New England (a subsidiary of public radio station WGBH) and are available to stream via the WGBH website. During the summer, WAMC Northeast Public Radio broadcasts Friday, Saturday, and Sunday BSO performances at Tanglewood reaching audiences across seven mid-Atlantic and New England states. Online engagement broadened the BSO's reach worldwide: 1.8 million unique users visited the BSO's website. Users streamed 44,000 BSO podcasts and BSO videos were accessed on YouTube 2,500,000 times. The BSO's social media following continues to grow. Social media followers (Facebook, Instagram, Twitter) totaled 467,738 across all BSO brands. 121,823 users accessed archival information on the BSO's online archival portal, collections.bso.org.</Desc>

        <ExplanationTxt>The Orchestra accounts for the effect of any uncertain tax positions based on a "more likely than not" threshold to the recognition of the tax positions being sustained based on the technical merits of the position under scrutiny by the applicable taxing authority. If a tax position or positions are deemed to result in uncertainties of those positions, the unrecognized tax benefit is estimated based on a "cumulative probability assessment" that aggregates the estimated tax liability for all uncertain tax positions. The Orchestra has identified its tax status as a tax exempt entity and its determinations relative to income that is considered related and unrelated as its only significant tax positions; however, the Orchestra has determined that such tax positions do not result in an uncertainty requiring recognition. The Orchestra is not currently under examination by any taxing jurisdiction. Its federal and state income tax returns are generally open for the past three years following the date filed by the appropriate tax authorities.</ExplanationTxt>

        <ExplanationTxt>The Boston Symphony Orchestra has a Conflict of Interest Policy that encompasses all employees and board members. The policy requires that Trustees, Officers, Advisors, Ex-Officio board members, members of a committee with board-delegated powers, senior staff members or any other person with substantial influence over the BSO disclose the existence of any potential or actual conflicts of interest to the Board or to the Executive Committee. The Board or Executive Committee then discusses and votes to determine whether an actual conflict of interest exists. If a conflict exists, the Board or Executive Committee evaluates the particular transaction or arrangement to determine the most reasonable course of action. The individual who disclosed the conflict must leave the Board or Executive Committee meeting during the discussion of, and the vote on, the transaction or arrangement that results in the conflict of interest. Additionally, the policy also requires any staff member that has information about a possible conflict, to report the matter, promptly, to his or her supervisor, the Director of Human Resources, or the Chief Financial Officer. The Director of Human Resources and the Chief Financial Officer will review the circumstances of the possible conflict with other, appropriate, management to make the determination about the most reasonable course of action. A breach of the conflict of interest policy is grounds for disciplinary action, up to and including termination. Additionally, on an annual basis, all Trustees, Officers, Advisors, Ex-Officio Board members, members of a committee with board delegated powers, senior staff members or any person with substantial influence over the BSO is provided with a copy of the policy and must sign a statement affirming that they have received, read, and understand the policy; they must also affirm that they agree to comply with the policy. As part of this Annual Notice of Policy, each individual is required to disclose any potential or actual conflicts of interest in writing. All responses indicating a potential or actual conflict are subject to review by the Board or Executive Committee as described above.</ExplanationTxt>
