Tetragon Financial Group Limited (TFG): Performance Report for Quarter Ended 31 March 2009

LONDON - Tetragon Financial Group Limited (TFG) is a Guernsey closed-ended investment company traded on Euronext Amsterdam by NYSE Euronext under the ticker symbol “TFG.”

In this quarterly update, unless otherwise stated, we report on the consolidated business incorporating TFG and Tetragon Financial Group Master Fund Limited.(1) References to “we” are to Polygon Credit Management LP, TFG’s investment manager.

Q1 2009 results at a glance: - Overview: The portfolio continued to face challenges in Q1 2009. In particular, rating agency downgrades of TFG’s investments’ underlying collateral (e.g., senior secured loans) to Caa1/CCC+ or below, coupled with corresponding decreases in the market values of such senior secured loans since 2008 year-end, placed significant and increased pressure on the performance of TFG’s investments. The majority of the Accelerated Loss Reserve (as defined herein) established at 2008 year-end was released in Q1 2009. Consequently, the Accelerated Loss Reserve was increased by approximately $290.0 million to seek to reserve against the impact of further losses arising from, among other things, additional rating agency downgrades. Financial Results: - Net Income: Consolidated Q1 2009 net income was a loss of $(414.3) million, compared with a Q4 2008 net income loss of $(187.2) million. - Cash Receipts: The investment portfolio generated $47.1 million of cash during Q1 2009 or approximately $0.37 per share (calculated using the average number of shares outstanding in TFGMF during the period based on quarter-end holdings). - Earnings per Share: EPS for Q1 2009 was approximately $(3.29) per share compared with EPS of $(1.48) during the prior quarter. - Net Assets and NAV per Share: Consolidated net assets were $723.4 million as of March 31, 2009, or $5.75 per share, down from $9.06 per share as of December 31, 2008. - Leverage: During Q1 2009, TFG repaid all outstanding (and previously defeased) repurchase and total return swap borrowings and as of the end of the quarter, had zero borrowings. As of March 31, 2009, TFG had a cash position of approximately $94.3 million, or approximately $0.75 per outstanding share, compared to a net long cash position of approximately $60.0 million as of the end of 2008. - Dividend: On April 23, 2009, the Board of TFG declared a dividend of $0.03 per share in respect of Q1 2009, which will be payable on May 21, 2009. Please refer to the website (www.tetragoninv.com) for additional information regarding the dividend, including the Optional Stock Dividend Plan. - IRRs: The weighted-average IRR ended the quarter at 10.6%, down approximately 3.2% from the end of Q4 2008. This decrease during the first quarter reflected, among other things, the impact of rating agency downgrades of TFG’s investments’ underlying collateral (e.g., senior secured loans) to Caa1/CCC+ or below, coupled with corresponding low market values of such assets. - Life-to-Date Net Loss Reserves:(2) Excess loss reserves declined in Q1 2009, with approximately $50.3 million of excess loss reserves having been factored into our IRR calculations as of March 31, 2009. At the end of Q4 2008, excess loss reserves were approximately $115.0 million. - Accelerated Loss Reserve: In December 2008, TFG established a balance sheet reserve calculated on a deal-by-deal basis against potential losses arising from, among other things, rating agency downgrades to TFG’s investments’ underlying collateral (the “Accelerated Loss Reserve”).(3) During Q1 2009, TFG’s investment portfolio faced significant and increased pressure from rating agency downgrades, Caa1/CCC+ or below rated underlying collateral, low market values of such collateral and resulting unrealized losses, with approximately $116.0 million of the Accelerated Loss Reserve being released. As a result of such unrealized losses and the increased uncertainty regarding the impact of those influences on the near-term performance of TFG’s investments, TFG increased the Accelerated Loss Reserve in March 2009 by $290.0 million. Consequently, at March 31, 2009, the Accelerated Loss Reserve totaled approximately $315.0 million compared to an initial reserve amount of $141.0 million as of December 31, 2008. - Hurdle Rate: The hurdle rate for Q2 2009 incentive fee has been reset at 3.8247% (Q1: 4.0603%) as per the process outlined in TFG’s 2008 Audited Financial Statements and in accordance with TFG’s Investment management agreement.(4) No incentive fee was paid for Q1 2009. Portfolio Summary: - Portfolio Size: As of the end of Q1 2009, the estimated fair value of the investment portfolio totaled $615.3 million, with look- through exposure to over $17.0 billion of leveraged loans. No new collateralized loan obligation (”CLO”) investments were made during the quarter. - Portfolio Composition: The portfolio currently consists of 61 CLO investments managed by 32 CLO managers.(5) - Collateral Performance: As of the end of Q1 2009, 24 or approximately 40% of our CLO investments were failing their most junior O/C test. (6) As O/C tests are breached, CLO structures may divert excess interest cash flows away from the equity tranche holders, such as TFG, to pay down the CLO’s debt thereby curing the O/C breach through deleveraging. Accordingly, the aforementioned 24 investments have ceased to generate cash flows to TFG or are expected to cease generating cash flows on the next applicable payment date. Once enough debt has been repaid to cure the O/C test breach, however, distributions of excess interest cash flows to equity tranche holders could resume to the extent not precluded due to the investments’ realized or unrealized losses. - Portfolio Credit Quality: As of March 31, 2009, the weighted-average percentage of corporate obligors rated Caa1/CCC+ or below in our 61 CLO investments was 11.4% compared to an approximate 7.8% weighted-average maximum level permitted under the terms of our investments.(7) The weighted-average WARF stood at approximately 2,758. Each of these foregoing statistics represents a weighted-average summary of all of our 61 investments.(8) Each individual investment’s metrics will differ from this average and vary across the portfolio. TFG Investment Weighted-Average Summary Q1 2009 Q4 2008 Q3 2008 Q2 2008 Q1 2008 Caa1/CCC+ or Below Obligors: 11.4% 7.6% 4.9% 4.4% 3.4% WARF: 2,758 2,577 2,490 2,472 2,443 - TFG and Market Default Rate: The lagging 12-month U.S. institutional loan default rate increased to 7.8% by principal amount as of March 31, 2009, according to S&P/LCD, up from 3.8% during 2008. (9) TFG’s lagging 12-month corporate loan default rate increased to 4.0% during the first quarter. (10) The significant pick-up in default rates was accompanied by generally weak post-default secondary market prices, which contributed to significant unrealized losses. Although realized recoveries may be higher than post-default market values, there exists the potential for coverage ratio (e.g., O/C) test breaches as a result of unrealized losses due to these low market values, which would have a negative impact on CLO equity returns. Q1 2009 Q4 2008 Q3 2008 Q2 2008 Q1 2008 TFG Trailing 12-Month Default Rate: (10) 4.0% 2.5% 1.5% 1.3% 0.8% Market Summary: - Loan Market: Secondary loan prices rallied notably during the course of the first quarter of 2009 in the context of limited new issue supply and slowed BWIC activity, driving a +9.8% quarterly return on the S&P/LSTA Leveraged Loan Index. (11) The breadth of first quarter price appreciation, however, was not evenly distributed as market participants began to differentiate loans based on credit quality, ratings and spread, among other factors, with higher quality BB rated loans posting a +13.6% return, single-B rated loans posting a +9.6% return and CCC+ rated loans dropping (7.6%) in the quarter. (12) Primary loan issuance in both the U.S. and Europe remained subdued during Q1 2009. Q1 2009 U.S. institutional leveraged loan volume fell to $3.2 billion, down slightly from $3.3 billion in Q4 2008. (13) Excluding DIP loan issuance, however, institutional loan volume amounted to only $829.0 million, the lowest level on record according to S&P/LSTA. European issuance similarly declined to a low of EUR1.2 billion, down from EUR1.3 billion in Q4 2008. (14) The loan market also saw an increase in amendment activity with issuers looking to modify loan documents to allow for, among other things, debt repurchases and exchanges. - Loan Market (continued): Although these repurchases or exchanges may not directly impair the underlying loans owned by our CLO investments, such actions may negatively impact the O/C and interest reinvestment/diversion tests, as the repurchase or exchange could prompt the rating agencies to temporarily rate such issuers or applicable loans as defaulted (i.e., a “Selective Default”), or permanently downgrade them to defaulted status or Caa1/CCC+ or below. According to S&P/LSTA, 30 issuers implemented repurchase amendments potentially amounting to approximately $5.0 billion in volume during Q1 2009. (15) Despite the generally negative view of corporate issuers conducting such repurchases by the rating agencies, the senior secured loans (TFG’s investments’ underlying collateral) directly affected by repurchases have traded up an average of 25.4% through April 3, 2009 as compared with 11.7% for performing loans broadly.(16) Thus, it would appear that the market may view repurchases (and exchanges) and the associated reduction in debt level and debt service of the applicable issuer as a near-term positive for the implicated loan. - Loan Prepayments: Q1 2009 institutional loan prepayments increased to $21.2 billion, up from $8.7 billion in the fourth quarter of 2008.(17) These levels amounted to a Q1 2009 repayment rate of 3.65%, as compared with 1.45% during Q4 2008.(18) Much of the quarter’s repayment activity was driven by M&A-motivated transactions. As described above, loan repurchases also contributed a notable source of reinvestment capital to institutional loan investors, as leveraged borrowers and their private equity sponsors sought to achieve balance sheet deleveraging. - CLO Issuance: New issue CLO volumes remained weak during the first quarter of 2009, totaling approximately $45.4 billion across 35 transactions.(19) European balance sheet CLOs dominated Q1 2009 issuance representing approximately 91% of total global volumes, with limited U.S. CLO issuance.(20) Given the significant role CLO vehicles have historically played in providing institutional loan financing, the re-emergence of CLO issuance or other forms of similar locked-in, term financing, remains an issue on the horizon, presenting potential refinancing risks for issuers in the future. - CLO Liability Downgrades: Both S&P and Moody’s have completed a previously announced review of their CLO ratings methodology and have retroactively incorporated a more severe stressed analysis in their ratings review. As a result, Moody’s and S&P have downgraded the majority of existing CLO mezzanine debt tranches. Senior debt tranches may also be affected as the rating agencies continue their review process. Such CLO liability downgrades, if significant enough, may result in the restriction of a collateral manager’s discretionary trading abilities, which could in turn impair their ability to manage the portfolio in a manner they would otherwise view as appropriate.

TFG Outlook:

Given the level of uncertainty and negative economic indicators surrounding global macro-economic and financial market conditions, we anticipate that the remainder of 2009 will continue to present a difficult operating environment for TFG. While the recent secondary loan market rally and recovery in certain segments of the capital markets offer glimmers of hope for a deceleration in the pace of economic decline, we believe that below investment grade-rated corporate borrowers, which represent the majority of our investments’ underlying portfolio, will continue to face challenging conditions in 2009. We, therefore, expect continued and increased pressure on TFG’s investments and results of operations in the near future.

During Q1 2009, we saw the dual stress of declining top-line revenues and limited access to capital take a toll on the leveraged loan markets as a large number of issuers defaulted or were downgraded to Caa1/CCC+ or below. We anticipate that this trend will continue in 2009, even as corporate borrowers seek to re-structure operations and balance sheets to cut costs and preserve liquidity. In addition to our concern with rising levels of defaults, Caa1/CCC+ assets, and low recoveries, we believe that longer recovery times and continued downward pressure on the secondary prices of distressed assets, may have a negative effect on the performance of TFG’s investments.

Finally, the risk of event of default (”EOD”) initiations as a result of senior O/C test breaches in CLO transactions has recently been a topic of debate among market participants. Although EOD provisions vary significantly across CLOs and we do not view the EOD risk as significant at this time, the consequences of an EOD when viewed independently of other risks could be substantial. We, therefore, continue to monitor developments on this issue.

As a result of underlying collateral defaults and increasing levels of Caa1/CCC+ or below-rated collateral (with low market values), among other factors, we continue to expect that TFG’s cash flows and net income may be lower and more volatile in 2009 than in prior years. We intend to continue to focus on the preservation of our existing investments during the remainder of the year and expect to evaluate any potential secondary CLO debt and/or equity investments on an opportunistic basis, as we seek to weigh their potential costs and benefits against our near-term goals.

This Performance Report constitutes TFG’s interim management statement as required pursuant to Section 5:25e of the Netherlands Financial Markets Supervision Act (Wet op het financieel toezicht, “FMSA”). Pursuant to Section 5:25e and 5:25m of the FMSA, this report is made public by means of a press release and has been filed with the Netherlands Authority for the Financial Markets (Autoriteit Financiele Marketen) and also made available to the public by way of publication on the TFG website (www.tetragoninv.com).

An investment in TFG involves substantial risks. Please refer to TFG’s website at www.tetragoninv.com for a description of the risks and uncertainties pertaining to an investment in TFG.

(1) TFG invests substantially all its capital through a master fund, Tetragon Financial Group Master Fund Limited (”TFGMF”), in which it holds 100% of the issued shares. Tetragon Financial Group LP (TFGLP), a U.S. “feeder fund”, has previously held an interest in TFGMF and accordingly, received a pro-rata allocation of the performance of TFGMF.

(2) The life-to-date net loss reserve is transaction-specific. It is calculated by subtracting the actual collateral loss for each transaction from the expected collateral loss, where the expected loss is a function of expected collateral size, TFG’s loss assumptions and the length of time the investment has been held.

(3) The Accelerated Loss Reserve like the life-to-date net loss reserve is transaction specific. Whereas the life-to-date net loss reserve is an adjustment embedded in TFG’s modeling assumptions, the Accelerated Loss Reserve is a direct adjustment to the fair value of an investment to account for the potential impact of certain unrealized and realized losses and the cumulative value of such adjustments will be and is evidenced in TFG’s financial statements.

(4) The hurdle rate is reset each quarter using 3M USD LIBOR plus a spread of 2.647858%.

(5) Excludes CDO-squared and ABS CDO transactions which were written off in October 2007. TFG continues to hold the economic rights to

these written-off transactions.

(6) Based on the most recent trustee reports available for our investments as of March 31, 2009.

(7) Excess Caa/CCC+ or below rated assets above the transaction specific permitted maximum holding levels are generally haircut in our

transactions at market value for purposes of the over-collateralization and/or interest reinvestment test ratios.

(8) Weighted by the original USD cost of each investment.

(9) LCD News: “Loan Defaults Surge in 1Q, Capped by Charter, Idearc”, April 1, 2009. Please note that TFG’s investment portfolio includes approximately 23.4% CLOs with primary exposure to European broadly syndicated senior secured loans and such loans are included in the calculation of TFG’s corporate loan default rate.

(10) Please note that the calculation of TFG’s lagging 12-month corporate loan default rate does not include certain underlying investment collateral that due to, among other things, the occurrence of an applicable issuer debt repurchase or exchange was assigned a “Selective Default” rating by one or more of the applicable rating agencies. Such Selected Defaults are included the S&P/LCD lagging 12-month U.S. institutional loan default rate discussed above. TFG’s lagging 12-month corporate loan default rate including such Selective Defaults was 4.3% for the period ending March 31, 2009.
