The Trust is a single-purpose trust that does not engage in any business or activity other than voting and holding the Trust&#160;Shares (as defined below) and certain closely related activities, such as distributing cash dividends and other distributions.

Common Stock repurchases are subject to the discretion of the Board and will depend upon MetLife, Inc.&#x2019;s capital position, liquidity, financial strength and credit ratings, general market conditions, the market price of the Common Stock compared to management&#x2019;s assessment of the stock&#x2019;s underlying value, applicable regulatory approvals, and other legal and accounting factors.

As such, these securities are categorized as Level&#160;1 (unadjusted quoted prices in active markets for identical assets) in three-level fair value hierarchy in accordance with fair value measurement guidance. Unrealized investment gains and losses on securities are recorded in the statements of operations and statements of changes in net assets.

Distributions of all other cash dividends shall be made by the Custodian to the Beneficiaries on the first business day following the 30th&#160;day after the Trust receives the dividends. Alternatively, the Trust&#160;Agreement provides that the Trustee may arrange with MetLife, Inc. for the direct payment by MetLife, Inc. of such cash dividends to the Beneficiaries. Historically, MetLife, Inc. has used the latter method. See &#x201c;&#x2014; Receivable from MetLife, Inc. and Dividends Payable to Trust&#160;Beneficiaries.&#x201d; The Trust&#160;Agreement further provides that pending such distribution, cash dividends (unless distributed directly by MetLife, Inc. to Beneficiaries) shall be invested by the Trustee in short-term obligations of or guaranteed by the United States, or any agency or instrumentality thereof, and in certificates of deposit of any bank or trust company having, at the time of the investment, a combined capital and surplus not less than $500,000,000. Dividends or other distributions in Common Stock will be allocated to the Beneficiaries in proportion to their Trust&#160;Interests and held by the Trustee as Trust&#160;Shares. Generally, all other distributions by MetLife, Inc. to its stockholders will be held and distributed by the Trustee to the Custodian and by the Custodian to the Beneficiaries in proportion to their Trust&#160;Interests within 60 days of receipt of such distribution by the Trustee, subject to limited exceptions.

In the event that dividends are undeliverable to the Beneficiaries, MetLife, Inc. retains such dividends until they are claimed by such Beneficiaries or escheated in accordance with applicable state law. Cash dividends that have been declared but are undeliverable to the Beneficiaries and the cash amounts of dividend checks that have not been cashed by the Beneficiaries have been recorded as a receivable from MetLife, Inc. and a liability of the Trust to such Beneficiaries.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Income Tax&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:6pt;text-align:justify;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;As a grantor trust, the Trust is not subject to United States federal income taxes.&lt;/span&gt;&lt;/div&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

Under this program, 3,370,923; 3,727,301; and 3,778,528 Trust Interests were redeemed, which generated net realized investment gains of $226 million, $229 million and $186 million for the years ended December&#160;31, 2025, 2024 and 2023, respectively. Beneficiaries allocated less than 1,000&#160;shares of Common Stock under the Plan are also entitled to purchase in the Purchase and Sale Program additional shares, subject to a minimum of $250 per purchase (or such lesser amount that would cause the Beneficiary to hold the 1,000 maximum number of Trust&#160;Interests). Under this program, 7,705; 10,859; and 17,194 Trust Interests were issued for the years ended December&#160;31, 2025, 2024 and 2023, respectively. The number of Trust&#160;Interests allocated to Beneficiaries will be adjusted for any shares of Common Stock purchased or sold in the Purchase and Sale Program such that the Trust&#160;Interests held by a Beneficiary will always equal the number of shares of Common Stock allocated to the Beneficiary.&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-top:9pt;text-align:justify;text-indent:18pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Beneficiaries may withdraw all, but generally not less than all, of their allocated shares of Common Stock from the Trust at any time by providing written notice to the Custodian. After the passage of sufficient time, unclaimed cash and Common Stock will be remitted as unclaimed property to the state of last known residence of the Beneficiary, as is the case with other types of unclaimed property. The schedule by which unclaimed property escheats varies by state, but is generally within three to five years of abandonment.&lt;/span&gt;&lt;/div&gt;</mpt:PurchaseAndSaleProgramTextBlock>
