Past performance is not a reliable indicator for future results. All financial investments involve an element of risk. The value of investments may rise and fall so you may get back less than originally invested. Investors should consider the risks, including lower returns, related to currency movements between their investing currency and the portfolio's base currency, if different. Total gross-of-fee returns for the composite (includes both capital appreciation and income) in the currency displayed terms, net of all transaction costs, any withholding taxes and direct expenses, but before management fees, custody and other indirect expenses. The Performance Presentation Report that is attached also reflects the gross and net of fees performance; however, note that the Performance Presentation Report reflects net performance of maximum institutional fees.

Certain types of debt instruments can be more sensitive to these factors and therefore more volatile. In addition, debt instruments entail interest rate risk (as interest rates rise, prices usually fall). At times, and particularly during periods of market turmoil, all or a large portion of segments of the market may not have an active trading market. As a result, it may be difficult to value these investments and it may not be possible to sell a particular investment or type of investment at any particular time or at an acceptable price. The price of an instrument trading at a negative interest rate responds to interest rate changes like other debt instruments; however, an instrument purchased at a negative interest rate is expected to produce a negative return if held to maturity. Despite the portfolio's intention to maintain a unit price of $10, there can be no assurance that a constant per unit price can be maintained as the value of its securities may fluctuate under certain conditions. * Short positions, unlike long positions, lose value if the underlying asset gains value. 1 The Average Quality is a market average (using a linear scale) of securities included in the rating categories. For all securities other than those specifically described below, ratings are assigned to underlying securities utilizing ratings from Dominion Bond Rating Service (DBRS). All ratings are subject to change. MFS has not independently verified benchmark data provided by the vendor which may be different than MFS. 2 Ratings are assigned to underlying securities utilizing ratings from Dominion Bond Rating Service (DBRS). All ratings are subject to change. 3 Prior to 1-Apr-12 net returns are not available because McLean Budden Limited chose not to disclose net returns.

MFS Investment Management has been independently verified for the periods 1-Jan-1988 through 31-Dec-2017. Verification assesses whether (1) the firm has complied with all the composite construction requirements of the GIPS standards on a firm-wide basis and (2) the firm's policies and procedures are designed to calculate and present performance in compliance with the GIPS standards. Verification does not ensure the accuracy of any specific composite presentation. Total Gross-of-fee returns in CAD (includes both capital appreciation and income) are net of transaction costs, withholding taxes and direct expenses, but before management fees, custody and other indirect expenses. Certain institutional accounts hold Canadian trusts subject to custody and other indirect expenses. From 1- Apr-2012 forward, certain accounts may be subject to Fair Valuation as conditions warrant and typical separate accounts utilize 4:00 PM (London Time) foreign exchange rates; retail products will use rates deemed most appropriate for daily NAV per share calculations. Prior to 1-Apr-2012 utilizes 12:00 PM (Eastern Time) foreign exchange rates. The possibility exists for performance dispersion between otherwise similarly managed accounts and also with the benchmark. Net composite returns are prepared by subtracting from the monthly gross returns one-twelfth of the maximum applicable annual institutional separate account fee. Total returns of the benchmark are provided for each period depicted, expressed in CAD. Source of Benchmark Performance: FACTSET. Benchmark returns and benchmark annualized 3-year standard deviation are not examined by independent accountants. 91 Day T-Bill Index - designed to reflect a portfolio of Canadian T-Bills over a 91 day duration. Composite Dispersion is measured by the asset-weighted standard deviation of account returns for all accounts in the composite for the full period. For composites containing less than six accounts for the full period, dispersion is deemed not meaningful. Prior to 1-Jan-2015, the maximum institutional separate account fee charged for this product was 25 bps. The net returns depicted in this report are based upon the historical max in effect for each of the periods depicted. The performance record of the old firm, McLean Budden Limited, is linked to the performance record of the new firm, MFS Investment Management, as of 1-Apr- 2012. Returns from 1-Apr-2012 forward shown on this report are calculated daily based on daily valuation and cash flow data. Monthly returns are calculated from the daily returns using geometric linking. Returns prior to 1-Apr-2012 shown on this report are calculated monthly using the Modified Dietz methodology, which may result in different return figures than those generated daily and linked using daily market values and daily cash flows. Prior to 1-Apr-2012 the minimum asset level for inclusion was two million Canadian dollars for institutional accounts and five hundred thousand Canadian dollars for private equity accounts; an account was eligible for inclusion as of its first full month of performance. Prior to 1-Apr-2012 net returns are not available because McLean Budden Limited chose not to disclose net returns. Because of this, the 2012 net of fees return is shown as n/a. The gross return for 1-Apr-2012 through 31-Dec-2012 is 0.87 and the net return for the same period is 0.68. Prior to 1-Apr-2012 the percentage of firm assets is not available because neither the assets as a percentage of the old firm nor the assets as a percentage of the new firm are relevant.
