Performance was driven by a narrow set of technology-focused firms riding high-growth megatrends, fanned by enthusiasm for artificial intelligence. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, stock picks in the United States and Japan detracted from the fund's performance versus the industry index. Positioning in China also hurt. By segment, the primary detractors were picks in the industrial machinery &amp;amp; supplies &amp;amp; components and transaction &amp;amp; payment processing services groups. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The fund's non-benchmark stake in Flywire returned -44% and was the largest individual relative detractor. Other notable relative detractors included overweight positions in SolarEdge Technologies (-82%) and Liberty Broadband (-26%). &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, from a regional standpoint, security selection in Singapore, and stock picks and an overweight in Taiwan, contributed to the fund's performance versus the industry index. By segment, market selection was the primary contributor, especially in semiconductors. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The fund's stake in Nvidia gained 186% and was the top individual relative contributor. Nvidia was the fund's largest holding. An underweight position in Apple (8%) and an overweight in Taiwan Semiconductor (+46%) also notably helped. Taiwan Semiconductor was also among our biggest holdings. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include decreased exposure to China and a higher allocation to the United States and Taiwan. By segment, notable changes in positioning include increased exposure to the semiconductors group. &lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

Performance was driven by a narrow set of technology-focused firms riding high-growth megatrends, fanned by enthusiasm for artificial intelligence. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, stock picking in the United States and picks in emerging markets, primarily in China, detracted from the fund's performance versus the industry index. By segment, market selection was the primary detractor, especially an underweight in pharmaceuticals. Stock selection in health care services also hurt. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The fund's stake in agilon health returned -68% and was the biggest individual relative detractor. This period we increased our position. Holdings in Penumbra (-39%), which was among the fund's biggest holdings this period, and 10x Genomics (-58%) also hurt. All of these detractors were non-benchmark positions. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, from a regional standpoint, an overweight in the United States and an underweight in emerging markets, primarily in China, contributed to the fund's performance versus the industry index. By segment, the biggest contributor to performance versus the index was security selection in biotechnology. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The top individual relative contributor was an overweight in Boston Scientific (+47%), the fund's biggest holding. Other top relative contributors included an overweight in Eli Lilly (+92%) - also among the fund's largest holdings at period end - and a non-index stake in Janux Therapeutics (353%). This period we decreased our investment in Eli Lilly. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include increased exposure to the health care services and health care technology industries. &lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

This move, approved by the Board of Trustees in November 2022, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency.&lt;/span&gt;&lt;/div&gt;

Performance was driven by a narrow set of technology-focused firms riding high-growth megatrends, fanned by enthusiasm for artificial intelligence. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, stock picking and an overweight in the United States and security selection and an underweight in emerging markets, primarily in China, contributed to the fund's performance versus the industry index. By segment, security selection was the primary contributor, especially within semiconductors and interactive media &amp;amp; services. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The top individual relative contributor was an overweight in Nvidia (+189%), the fund's largest holding. Other notable relative contributors included a non-index stake in Meta Platforms (+74%) and an overweight in Taiwan Semiconductor (+52%). Meta Platforms and Taiwan Semiconductor were also among our largest holdings. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, from a regional standpoint, security selection in Europe ex U.K., primarily in Netherlands, and an underweight in Japan detracted from the fund's performance versus the industry index. By segment, the primary detractors from performance versus the index were stock selection and an underweight in technology hardware, storage &amp;amp; peripherals. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The fund's stake in SolarEdge Technologies returned -83% and was the biggest individual relative detractor. This period we increased our investment. Other notable relative detractors included our non-index stake in Farfetch (-70%), which was not held at period end, and an overweight in MongoDB (-20%), which was among the fund's biggest holdings this period. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include increased exposure to Taiwan. By segment, notable changes include higher allocations to the semiconductors and movies &amp;amp; entertainment groups. &lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

This move, approved by the Board of Trustees in November 2022, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency.&lt;/span&gt;&lt;/div&gt;

Performance was driven by a narrow set of technology-focused firms riding high-growth megatrends, fanned by enthusiasm for artificial intelligence. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, security selection and an overweight in the United States and picks and an underweight in emerging markets contributed to the fund's performance versus the industry index. By segment, security selection was the primary contributor, especially within semiconductors.&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The top individual relative contributor was our non-index stake in Nvidia (+194%), which was one of the fund's biggest holdings. This period, we reduced our investment in Nvidia to manage the position size. Other notable relative contributors included Meta Platforms (+76%) and a non-index stake in Arista Networks (+80%). Meta Platforms and Arista Networks were also among the fund's largest holdings. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, from a regional standpoint, underweights in Europe ex U.K. and Japan detracted from the fund's performance versus the industry index. By segment, the primary detractor was an underweight in wireless telecommunication services. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The biggest individual relative detractor was an overweight in Liberty Broadband (-27%), which was among the fund's largest holdings this period. Other notable relative detractors included an overweight in Naver (-24%) - which was a position we established this period - and a non-holding of Tencent Music Entertainment Group, an index component that gained 110%. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include increased exposure to China and Singapore.

This move, approved by the Board of Trustees in November 2022, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies.

Performance was driven by a narrow set of technology-focused firms riding high-growth megatrends, fanned by enthusiasm for artificial intelligence. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, stock picks in Japan and stock selection in emerging markets, primarily in China, detracted from the fund's performance versus the industry index. By segment, security selection was the primary detractor, especially within industrial machinery &amp;amp; supplies &amp;amp; components. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The fund's stake in OPT Machine Vision Tech returned -59% and was the largest individual relative detractor. Positions in Dongguan Yiheda Automation (-48%) and Estun Automation (-42%) also hurt. All of these detractors were non-benchmark positions. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, from a regional standpoint, an overweight in the United States and an underweight in emerging markets, primarily in China, contributed to the fund's performance versus the industry index. By segment, the biggest contributor to performance versus the index was security selection in semiconductors. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The fund's stake in Nvidia gained 187% and was the top individual relative contributor. Nvidia was the fund's top holding. Our positions in Taiwan Semiconductor (+38%) and Teradyne (+38%) notably helped; both were also among our biggest holdings. All of these contributors were non-benchmark holdings.&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include decreased exposure to China and a higher allocation to the United States. By segment, notable changes in positioning include increased exposure to the semiconductor materials &amp;amp; equipment segment.&lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;

This move, approved by the Board of Trustees in November 2022, was deemed in the best interest of shareholders. The new ETF and its former corresponding fund have identical investment objectives and fundamental investment policies and have substantially similar investment strategies. Returns prior to the conversion are those of the former corresponding fund. Fidelity believes that the conversion will provide multiple benefits for investors of the fund, including lower net expenses, additional trading flexibility, increased portfolio holdings transparency and the potential for enhanced tax efficiency.&lt;/span&gt;&lt;/div&gt;

Performance was driven by a narrow set of technology-focused firms riding high-growth megatrends, fanned by enthusiasm for artificial intelligence. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Against this backdrop, an overweight in the United States and an underweight in emerging markets, primarily in China, contributed to the fund's performance versus the industry index. By segment, security selection was the primary contributor, especially within financial exchanges &amp;amp; data. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The fund's non-index stake in MicroStrategy gained 265% and was the top individual relative contributor. Other notable contributors included a non-index stake in Baldwin Insurance (+65%), which was one of the fund's largest holdings, and an overweight in Coinbase Global (+210%). The positions in MicroStrategy and Coinbase Global were established this period. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;In contrast, from a regional standpoint, stock picks in the United States and stock selection and an underweight in Europe ex U.K. detracted from the fund's performance versus the industry index. By segment, the primary detractor was an overweight in transaction &amp;amp; payment processing services. &lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;The fund's non-index stake in Flywire returned -43% and was the biggest individual relative detractor. We increased our investment in Flywire during the period. A non-index stake in dLocal returned -23% and was the second-largest detractor. Both Flywire and dLocal were among the fund's largest holdings this period. Our stake in Worldline (-67%), which was not held at period end, also hurt. &lt;span&gt;&#160;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;&lt;li style="margin:5px 0px 2px 24px;padding:0px;"&gt;&lt;span style="font-family:'Fidelity Sans';font-size:12px;color:#000000;font-style:normal;font-weight:normal;"&gt;&#x2022;&lt;span style="padding-right:10px"&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:'Fidelity Centry Std Light Cond';font-size:13px;color:#000000;font-style:normal;font-weight:normal;"&gt;Notable changes in positioning include increased exposure to the U.K. and a lower allocation to Uruguay. By segment, notable changes include increased exposure to the financial exchanges &amp;amp; data industry and a lower allocation to property &amp;amp; casualty insurance.&lt;/span&gt;&lt;/li&gt;&lt;/ul&gt;
