Non-GAAP Measures

Westaim
Westaim uses both international financial reporting standards (as issued by the International Accounting Standards Board) (“IFRS”) and non-GAAP measures to assess performance. Westaim cautions readers about non-GAAP measures that do not have a standardized meaning under IFRS and are unlikely to be comparable to similar measures used by other companies.

Book Value Per Share (“BVPS”), Adjusted profit (loss) and comprehensive income (loss) and Adjusted earnings (loss) per share – diluted, excluding unusual items are non-GAAP measures – see section 15 of Westaim’s MD&A for the quarter ended March 31, 2021 for a discussion of these measures including a reconciliation to the Corporation’s IFRS results.

Skyward Specialty
Skyward Specialty uses United States generally accepted accounting principles (“US GAAP”) and non-GAAP measures to assess performance. Please refer Westaim’s MD&A for the quarter ended March 31, 2021 for Skyward Specialty’s non-GAAP measures.

Arena FINCOs and Arena Investors
Arena FINCOs and Arena Investors uses both US GAAP, IFRS and non-GAAP measures to assess performance.

Net Return on the Arena FINCOs investment portfolios is the aggregate of investment income, net of gains (losses) on investments less interest expense, management, asset servicing and incentive fees, and other operating expenses of the Arena FINCOs divided by average carrying values for the Arena FINCOs, for the period.

Gross Return on the Arena FINCOs investment portfolios is the aggregate of investment income, net of gains (losses) on investments less interest expense divided by average carrying values for the Arena FINCOs, for the period.

Realized IRR: Realized calculations are presented net of investment level expenses and gross of fund level fees (e.g. management and incentive fees), which can impact returns significantly.

Current IRR reflects all investment activity, i.e, prior actual cash flows and future projected cash flows (which are discounted as of the reporting date), from the inception of each applicable investment through March 31, 2021. The current IRR may not be representative of the realized IRR upon exit of each investment, which may increase or decrease.

Underwritten IRRs: Investment-level gross underwritten IRR represents the internal rate of return prior to or at the time of making the initial investment as reflected in and supported by loan agreements, including, but not limited to, note purchase agreements and origination agreements. The underwritten IRR is one of many metrics considered by Arena prior to investment and is not typically updated after the initial funding date. The underwritten IRR may be presented as a single percentage or a range. Such gross IRRs are estimated and do not take into account any entity level management fees, incentive allocation and/or any other associated fees, all of which may significantly reduce the net return received attributable to any investment. These underwritten IRRs are not a proxy for investment performance for any strategy or fund; investment performance may be provided upon request. The underwritten IRRs disclosed herein are being presented for the purpose of providing insight into the investment objectives of Arena, detailing anticipated risk and reward characteristics in order to facilitate comparisons with other investments and for establishing a benchmark for future evaluation of Arena’s strategy. The IRRs are also being presented because financially sophisticated investors may find this information useful in determining where Arena’s strategies may fit within their investment portfolios. The IRRs included in this presentation are not intended, and must not be regarded, as a representation, warranty or prediction that any Arena vehicles will achieve any particular return with respect to any particular investment opportunity or for a particular time period, or that Arena and its investors will not incur losses. In evaluating these IRRs, it should be noted that (a) there can be no assurance that Arena will be able to source and consummate investments of the type it is seeking to make and (b) the assumptions underlying the IRRs may prove not to be accurate or not materialize. There can be no assurance that the objective of the investment shown can be met or that substantial losses will be avoided.

All amounts herein are in United States dollars unless otherwise indicated. Certain comparative figures have been reclassified to conform to the presentation of the current year, and certain totals, subtotals and percentages may not reconcile due to rounding.

Important Disclosures

Arena Investors
The following is being provided solely in relation to Arena Investors, LP, its funds, subsidiaries and affiliates:

Returns shown are unaudited. Past performance is not indicative or a reliable indicator of future performance. Actual results may vary.

The information set forth herein does not purport to be complete, is unaudited and subject to change. Arena has no obligation to update or revise such information. Unless otherwise stated, the information contained herein is current as of the date of the presentation.

This document does not constitute investment advice nor is it a recommendation or an offer of investment advisory services or products. No person in any jurisdiction may treat this document as a solicitation or offer of any advisory product or service. A prospective investor must rely solely on the terms and associated disclosures in any final offering memoranda, investment management agreement and associated subscription documents (if any), which would constitute the only basis upon which offerings of any product or service may be made.

Investments in Arena vehicles are speculative in nature and involve risk. There can be no assurance that investment objectives will be achieved and investment results may vary substantially over time. These investments are not intended to be a complete investment program for any investor. There is no secondary market for an investor’s interest in Arena funds and none is expected to develop. Arena’s funds are not registered under the Investment Company Act of 1940 and accordingly are not extensively regulated. Opportunities for redemption and transferability of interests are restricted, so investors may not have access to capital when it is needed. Leverage may be employed in the funds, which can make investment performance volatile. Valuation of the investments may involve uncertainties and the exercise of judgment. An investor should not make an investment unless the investor is prepared to lose all or a substantial portion of its investment. The fees and expenses charged in connection with investments may be higher than the fees and expenses of other investment alternatives and may offset profits, and the performance-based compensation paid to Arena may create an incentive for Arena to make more speculative investments than would otherwise be the case. Arena has total authority and control over its funds and the use of a single advisor applying generally similar investment programs could mean a lack of diversification and, consequently, higher risk. For a comprehensive list of risk factors, an investor must review the risk factors as specified in the related confidential information memorandum for a specific fund or investment management agreement, which will be made available upon request.

The information provided herein should not be considered a recommendation regarding a particular investment. The actual and potential investments discussed herein are meant to be examples of Arena’s investment approach. It should not be assumed that any of the investments discussed herein will prove to be profitable, or that the investment recommendations or decisions made by Arena in the future will be profitable. The particular investments discussed herein are those that most closely represent the current average-sized Arena investment in a particular category (Corporate Private Credit, Real Estate Private Credit, Commercial and Industrial Assets, Structured Finance and Consumer Assets).

In addition, performance of market indices is being provided for the purpose of making general market data available as a point of reference only. We believe there are no known directly comparable indices for the Arena Special Opportunities Strategies composite which
is comprised of the Arena Special Opportunities Fund, LP and Arena Special Opportunities (Offshore) Master, LP (collectively the “Fund”). The Fund’s investments are not limited to the investments listed by the market indices. The Fund may invest in different securities and engage in different trading strategies from the indices. In addition, it should be noted that the sector, industry, stock and country exposures, volatility, risk characteristics and holdings of the Fund differ materially from those of the indices. The indices do not reflect fees and expenses associated with the active management of portfolios. The performance returns of the indices were obtained from Bloomberg and other third-party sources and include the reinvestment of earnings. Although Arena believes these sources to be reliable, it is not responsible for errors or omissions from these sources.

Market indices used: The Standard & Poor’s LSTA Leveraged Loan 100 Index is a capitalization-weighted syndicated loan index that seeks to mirror the performance of the 100 largest syndicated loans in the levered loan market. Leveraged loans are senior secured debt obligations rated below investment grade. The index information provided is for illustrative purposes only. The Fund’s strategy does not track the index and can significantly vary than that of the performance on the indexes provided.
