Performance Participation Interest Examples


 


The following examples have been provided as
a worked example to illustrate the calculation of the Performance Participation Interest. These examples have been provided for
illustration purposes only


 


		1.	Disbursement Date in respect of the relevant Tranche (Year
1)



 


		•	Disbursement of Tranche = EUR 10,000,000



 


		•	Disbursement Date Market Capitalisation = EUR 160,000,000



 


		•	Disbursement Date Notional Equity Proportion = (EUR 10,000,000) x (2%) x (5 years) / (EUR 160,000,000)
= 0.00625 (or 0.625%)



 


		2.	Maturity Date in respect of the relevant Tranche (Year
5)



 


		(a)	Upside Scenario



 


		•	Maturity Date Market Capitalisation (in relation to the Maturity Date or on any date earlier than
the Maturity Date in the event of a prepayment or an acceleration of all or part of that Tranche) = EUR 200,000,000



 


		•	Performance Participation Interest = 0.00625 x EUR 200,000,000
= EUR 1,250,000



 


		(b)	Downside Scenario



 


		•	Maturity Date Market Capitalisation (in relation to the Maturity Date or on any date earlier than
the Maturity Date in the event of a prepayment or an acceleration of ail or part of that Tranche) = EUR 100,000,000.



 


		•	Performance Participation Interest = 0.00625 x EUR 100,000,000
= FUR 625,000

Schedule G


 


Existing Indebtedness


 


	Source	 	Outstanding amount	 	De-minimis repayment provision
	 	 	 	 	 
	8% option bond due 1 January 2018	 	EUR 4,930,000 (of which EUR 1,500,000 are held by Borrower)	 	N/A
	 	 	 	 	 
	6% subordinated convertible bond due 1 January 2021	 	EUR 83,000	 	Paragraph 4(4) of the terms of the bond states:
	 	 	 	 	 
	 	 	 	 	“Early Redemption for reasons of minimal outstanding Principal Amount. The Issuer may at any time redeem all, but not part of the Bonds at their Principal Amount, together with interest accrued thereon until (but excluding) the date of redemption if at any time the Principal Amount of the Bonds outstanding is below 15% of the initially issued amount of Bonds.  Notice of early redemption shall be given not less than 30 nor more than 60 days before the day fixed in the notice on which any Bonds become due for early redemption.  The Provisions of the preceding paragraph shall apply accordingly.”  
	 	 	 	 	 
	 	 	 	 	The provisions of the preceding paragraph state that such notice will be irrevocable and must state the date of the early redemption and the last day on which Conversion Rights may be exercised by Bondholders.
	 	 	 	 	 
	 	 	 	 	The initially issued amount of the Bonds was 49,990 bonds in a total nominal amount of EUR 4,999,000, so the de minimis threshold is reached when EUR 749,850 or less are outstanding (which is already the case as at the date of this Contract).
	 	 	 	 	 
	 	 	 	 	Defined terms used above have the meaning given to them under the terms and conditions of the 6% subordinated convertible bond due 1 January 2021.

	6% subordinated convertible bond due 1 January 20221	 	EUR 2,663,400	 	Paragraph 4(3) of the terms of the bond states:
	 	 	 	 	 
	 	 	 	 	“Early Redemption for reasons of minimal outstanding Principal Amount.  The Issuer may at any time redeem all, but not part of the Bonds at their Principal Amount, together with interest accrued thereon until (but excluding) the date of redemption if at any time the Principal Amount of the Bonds outstanding is below 15% of the initially issued amount of Bonds, Notice of early redemption shall be given not less than 30 nor more than 60 days before the day fixed in the notice on which any Bonds become due for early redemption. The provisions of the preceding paragraph shall apply accordingly.”
	 	 	 	 	 
	 	 	 	 	The provisions of the preceding paragraph state that such notice will be irrevocable and must state the date of the early redemption and the last day on which Conversion Rights may be exercised by Bondholders.
	 	 	 	 	 
	 	 	 	 	The initially issued amount of the Bonds is EUR 4,999,000. Therefore, the Borrower may repay the convertible bond under the above de-minimis clause once the outstanding amount reaches EUR 749,850 or falls below that amount.
	 	 	 	 	 
	 	 	 	 	Defined terms used above have the meaning given to them under the terms and conditions of the 6% subordinated convertible bond due 1 January 2022.


 


 



1 (1)
includes the following covenant :


 


“Each Bondholder is entitled to declare
due and payable by submitting a notice of termination (Termination Notice”) its entire claims arising from the Bonds and
demand payment of their Principal Amount, plus interest accrued on the Principal Amount until (but excluding) the day of actual
redemption, if


 


the Issuer, for any reason whatsoever, fails
within 30 days after the relevant payment date to pay any amounts due and payable on the Bonds; or


 


the Issuer Exceeds the Permissible Indebtedness
by debt borrowing.


 




    	71



     


    

 


The issuer ‘Exceeds the Permissible Indebtedness’
if by debt borrowing both (i) the Net Financial Indebtedness of the Issuer exceeds EUR 25 million, and (ii) the Net Indebtedness
Quota of the Issuer exceeds 4.0. Exempt are any debt borrowings for the purpose of financing the claims of Bondholders arising
out of these Bonds.


 


“Net Financial Indebtedness’ means
the sum of long-term financial liabilities and short-term financial debt, less cash and cash equivalents.


 


“Net Indebtedness Quota” means
the quotient of Net Financial Indebtedness divided by EBITDA.


 


“EBITDA” means the profit or loss
for the period, adjusted for depreciation and amortization, tax, interest expenses and interest income.


 


The calculation of Net Financial Indebtedness,
Net Indebtedness Quota and EBITDA shall be based on the respective most recent published annual group or interim quarterly financial
reports at the time of the debt borrowing. Insofar as the audited financial report shows Net Financial Indebtedness, Net Indebtedness
Quota and/or EBITDA, the respective calculation shall be binding both for the Issuer and the Bondholders.


 


The Issuer shall not be considered to Exceed
the Permissible Indebtedness if the Net Indebtedness Quota exceeds 4.0 due to a reduction of the EBITDA.”
